Loading Controls Dynamically problem on ASP.Net 2.0

Hi Folks,

If you load your controls dynamically on asp.net 2.0 web site,you will face a problem that all handlers of server side controls doesn't work and not fire on the server side.

Even you try to put a break point on your server side handler,it will not fire,this is not because of a problem on any of your user controls or your code has something wrong.

the problem is : if you try to write the same line of code on asp.net 1.1 web application this problem will not happen at all,and if you tru to load the same controls on asp.net 2.0 web site the problem will happen.

The solution and Tip for this problem,is to just give an ID for your user control which will be loaded dyamiccly,and the problem will not happen.

This the code which run on asp.net 1.1 perfectly and doesnt run on asp.net website :

C#:
PlaceHolderID.Controls.Clear();
Control c = Page.LoadControl(”UCPath”);
PlaceHolderID.Controls.Add(c);

The Solution :
C#
PlaceHolderID.Controls.Clear();
Control c = Page.LoadControl(”UCPat”);
c.ID = “IDForYourControl“;
PlaceHolderID.Controls.Add(c);

Hope this helps.

WCF Security Limitations

Hi Folks,

i discovered some points which you have to take it in your consideration if you are working to deisgn a WCF solution,specially the security issues with WCF :

1) You can't apply Message Level security with WCF Streaming which is used to pass Large binary data between the service and WCF Clients.

2) In Case you want to apply WCF Streaming on your WCf Host,you have to change your security level from message to transport level.

3) Maximum received message size to a WCF service is 64 KB;if the message exceeds this limit size the WCF runtime will throw an exception.

Note : if you want to increase the Max. Message Size,on the Bindings properties you can change/increase the message size as per your request.


Hope this Tips helps WCF Architect and Developrs :)

Implementing a WCF Service with High Performance

Hi Folks,

WCF gives the developer the tools to provide high performance for your WCF Service,once of the key features to provide high performance WCF Service caled "Service Throttling";this concept simply provide you the values you want to set to manage the following:

1) Maximum Concurrent sessions.
2) Maximum Concurrent Calls.
3) Maximum Concurrent Instances.

These values should be set on the host app of the service,and the admin has to monitor the server which host WCF Services to monitor the perfomance of the running WCF services.

To Implement Service throttling on your service,you have to write this code before open the serviceHost Object :

// Required for the ServiceThrottlingBehavior class
using System.ServiceModel.Description;
…
ServiceHost host = new ServiceHost(…);
ServiceThrottlingBehavior throttleBehavior = new ServiceThrottlingBehavior();
throttleBehavior.MaxConcurrentCalls = 40;
throttleBehavior.MaxConcurrentInstances = 20;
throttleBehavior.MaxConcurrentSessions = 20;
host.Description.Behaviors.Add(throttleBehavior);
host.Open();

Note : that we set these values before open the servicehost object.

Take care of the following Tips :
1) Default Concurrent Instances is Int32.Max = 21474836467
2) Default Concurrent Calls is 16
3) Default Concurrent Calls is 10


Hope this helps for WCF developers :)

Reliable Sessions on WCF

Hi folks,

WCF give a greate feature called Reliable Session,when you enable the reliable sessions on your service and your clients,you give your clients a very great advantage which is the client app can sends messages to the Service without waiting for the service reply.

One will ask ? what's the harm for the client app to wait for Service reply ? if the service is busy,and client will wait and blocked until getting the response fro mthe service.and if you put a timeout for your bindings,then excpetion will be thrown against your client.

another point,in cases like client wants to invoke the serivce and doesnt want to wait,you will use the OneWay operation attribute on your service but this will lead to the blocking of your client until getting the response.to avoid this just enable the reliable sessions property on your bindings on the service and the client.

Note : mark your serivce as ConcurrencyMode.Multiple attribute will not avoid the client blocking,but it will change the way of the serivce how it deals with the incoming messages since the default mode for all services is single threaded.


Hope this tips helps........... :)

OneWay Operation in WCF

Hi Folks,

This post is showing one of the key important features available on WCF as a unified Communication platform,as a .net developer you can read this post and understand the changes and theu pdates that have been done on the WCF.

Simply,WCF is to create WCF Services,these services can be consumed or used by client app.

if you are familiar with Web services,you can understand the idea of this post wich is the OneWay Operation in WCF.

simply Operation is your service or function in your service;since your service can have more than operation .

What does "OneWay operation WCF " ? it means when the client try to consuem oyur service,it doesnt need to wait to get the respornse of the service.

this is cool,this means that it gives the same behavior of the asynchronous call on Web Services;but since we have more than 1 way to implement Asynch Call in the WCF;this one of the options.

How to mark your operation as a OneWay Service

[OperationContract(IsOneWay = true)]
void MyOperation(string id);

Cons :

The OneWay Operation has to be Void and you cant return any value or even valyes by ref or out parameters.


Tip : in case you choose your operation as a oneway operation,dont forget to put the Receive and Ope Time out properties on the Binding Information of the WCF service.

Managing your WCF Service Context & State

Hi Folks,

when you create a host for your service,this host manage the context of the service and its states,for this reason,you have to take care how can you configure your host to keep your service under control without any issues regarding the security or performance.

One point regarding the Service performance which is the Service Context:did u ask your self if 1000 Clients call your service ? how manay instances will be created from your service ?

To answer this question,you have to know which mode are your setting your service to work with.

1) Per Session Mode :

How to Implement : Mark your service class with this attribute

C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]

Answer : 1000 sessions will be created.

2) Per Call Mode :

How to Implement : Mark your service class with this attribute

C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]

Answer : Per call the host will create an instance for your service.
This mode give better performance incase the client still opened and not active rather than the prev. mode.

3) Single Mode :

How to Implement : Mark your service class with this attribute

C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]


Answer : 1 instance and all clients can share data between them.

Hope this helps.

Breaking and Non-Breaking change on WCF service

Hi Folks,

In this post i want to mention and differentiate between 2 types of changes on any WCF service.

when you are developing a wcf servive,the changes might occur,and before any change you have to test and examine does this change will affect the service clients ?

The changes you have done on a WCF Service,it will affect the client anyway,but the type of the change it might break the client which yield to the client will not work OR it might yield to the client can continues working in a healthy way.

NON Breaking Changes:
Implicit or Explict security checks,change on the logic of the function,add extra binding configuration...etc

Breaking Changes:
Change Method paramaters , Add new paramaeters,change return types,delete methods.

Any Change which will break the client,you have to inform the client owner with the change you have done,to keep the client working.

Hope this helps.

Recover SQL 2005 DB passwords

Hi Folks,

I got an urgent request of one of my friends asking for a solution to recover SQL 2005 DB passwords,the situation was as follows:

He took a backup of SQL 2005 DB and set the password option on SQL 2005,and when he tried to restore the DB,SQL 2005 request the password which he forgot it.

My First question was: did he protect the bak file from SQL 2005 or not ? after i got that he protect the DB from SQL 2005,i started to search for third party solution to fix this problem since this DB contains very sensitive information.

I found a third party to recover the SQL 2005 user accounts passwords ,try it now :
http://www.safe-install.com/programs/sql-password.html

The security hole which i discovered that this program can't recover the SQL server passwords if the SQL Engine was configured to use only Windows Authentication Mode; and this is considered as an important security point when we use MS Products with Windows Authentication mode ONLY.

From this post,you have to take care of your SQL installation which mode is an appropriate to your organization.
Hope this helps.

In case you put the password on the bak file,then no way to do any kind of restore to this DB;see more on this article : http://mssqltips.com/tip.asp?tip=1108

.Net 3.0 & .Net 2.0 Design Tips

On the above figure it shows the following:

1) New Technologies coming with .net 3.0 Framework (CF,WF,PF,CardSpace).

2) The Base of .Net Framework 3.0 working on the .Net Framework 2.0,this means any application on 2.0 will not have any interoperability issues or problem to work on .net 3.0 unlike the shift between .net 1.0 to 2.0.

3) Move from Web services to WCF :
-System.ServiceModel is the namespace which provides the whole funcaitonality of WCF.
-Implementing the interface and the implementaiton clsses to implement a WCF service.
(Service Contract,Operation Contract,DataContract)
- Binding information on the web.config,Transport protocol,Endpoints information.

- using svcUtil tool to create proxy classes and clients to your service.

-Integration with COM+,WS,MSMQ,.Net Remoting....etc with WCF

4 Tenets of Service Orientation

Hi Folks,

This post is to show and describe the 4 tenets of SOA and how is it implemented in WCF Technology in a way,how can WCF to avoid the wellknown pitfalls of using current technologies such as (WSE):

1) Boundaries are explicit :
Applications is communicating to each other by sending and receiving messages to each other.

2) Services are autonomous: you can't control any service out of your organization boundaries.
Your solution should be loosly coupled ,so it can tolerate these changes and continue running if one or more services are un available.


3) Services share schema,contracts not classes or types: simply each service publish the schema of the data which will be exchanged between the service and clients and how can be binded to the clients,these information is used by clients to consume the published services.


4)Compatability is based on policy:Schemas and contracts exposed by the service is define the "Shape" of the service.

if you familiar with WS Enhancements,it has its specification on WS-Security,WS-Interoperability....etc which has been encapsulted into the WCF unified platform.

Deploy WSS 3.0 Web Part

Hi Folks,

This post i will explain how can you dpeloy a wss 3.0 webpart to your shareporint server.

the steps as follows:

1) on your class library,open project properties.
2) select signing tab.
3) check sign assembly check box and select new,and give your snk file a proper name , Close and save.

You will notice that a new snk file has been added to your solution which is used to sign your assembly and give it a strong name.

4) Dont forget to build the dll to be signed with the created strong file name.
5) add your strong name assemly to the GAC using VS command line

GacUtil -i MyAssembly.dll

You can check that the file assemly has been imported to GAC y navigating to :
C:\Windows\assembly

you will find your dll,this means that your string name dll has been imported successfully to GAC (Global Assembly Cache)

6) Right click on your srong name assembly and select properties,and copy the public token.

7) Create a manafiset file in your project "Manifest.xml"

8) Paste the public token you have saved to the PublickKeyToken attribute under safeControls element in Manifest.xml file.

9) Manifest.xml file should be Content file on the build action property on VS.

on the above steps,your web part is ready to be packaged up to the shareporint server,to create the cab file of this webpart do the following:

10) add a new project, Cab Project.
11) add the primary output / content files to the Cab Project.
12) Build the CaB Project.
13) after building the CAB Project,Rename it to wsp (SharePoint solution file).
14) Take this file (wsp) and insert it using SBS admin tools :
stsadmin -c addsolution -filename MyWebPartCab.wsp

15) On Solution Management on SharePoint Central administration site, you will see the imported solution file which oyu have did on the previous step.

16) Select the solution and click on Deploy Button.


Now you have finished deploying your webpart and you can add it to any web application in your WSS Sites.

DataContract Vs. Service Contract

Hi All,
In WCF,Some new terminolgies are come up for .Net Developers,but not for COM,DCOM developers,Since the developers who are familiar with developing Dist. Application used to divide their code to interface and implementations.

The same concept is exist on WCF Tech.,Since the devleopers should divide his servce to :
1- Data 2- Operations.

**Data represented by creating DataContract which expose the data which will be transefered /consumend from the serive to its clients.

**Operations which is the functions provided by this service.

To write an operation on WCF,you have to write it as an interface,This interface contains the "Signature" of the methods tagged by ServiceContract attribute,and all methods signature will be impelemtned on this interface tagged with OperationContract attribute.

and to implement these serivce contract you have to create a class which implement the interface and the actual implementation will be on that class.


Code Below show How to create a Service Contract:

[ServiceContract]
Public Interface IEmpOperations
{
[OperationContract]
Decimal Get EmpSal(int EmpId);

}

Class MyEmp: IEmpOperations
{
Decimal Get EmpSal()
{
// Implementation of this method.
}
}

Hope now you can differentiate between Data Contract,Service Contract and OperationContract.

DataContract attribute in WCF

Hi Folks,
This is the First post of WCF in my blog,i was little busy with Team System Blogging :),anyway,let's assure one of the first important aspects of WCF programming which is "Contract First" Approach,This approach let the developer or Architect to design his service before starting developing it.
First thing you will do when you create a WCF is creating the Data Contract,which is the Contract that specifies the data will be exchanged between the service and it clients,suppose we need to create a WCF serice which expose Employee Data,The Data Contract will be as follows:

namespace Emp
{

[DataContract]
Class Employee
{
[DataMember]
int EmpId;

[DataMember]
string EmpName;

[DataMember]
string DeptName;
}
}

DataMember attribute you have to put it on each data member in the class in case you want to serialize and deserialize this member which is used on passing or retireving data from this data contract.

DataContract Attribute can be applied on :
1) Classes.
2) Enumerations.
3) Structures.


Hope This helps.

MS Process Editor Bug !!

Hi All,

This post i will show a bug in MS Process Editor, When you try to customize the Process (Workitems Types,Iteration,.....etc) when you try to create a new project with it,you will get an error,this error will be customized based on the customized portion in yur process:
1) Iteration Error or
2)Tasks Error or
3)Work Type Error.

if you want to produce this error ,Do the following:


1) Open Your process.


2) Delete and modify the existing iterations.


3) Upload your Modified Process.


4) Try to create a project using this Process Template,and you will get this error :


Click on the Log File,The first exception is :


---begin Exception entry---Time: 2007-05-30 11:50:22ZModule: Work Item TrackingEvent Description: TF26214: Cannot save the work item. Fields with errors: Iteration Path,IterationIDException Type: Microsoft.TeamFoundation.WorkItemTracking.Client.ValidationExceptionException Message: TF26202: Validation failed. Field 'Iteration Path' not supported.Stack Trace: at Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItem.PreValidate() at Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItem.PreBatchSave() at Microsoft.TeamFoundation.WorkItemTracking.Client.BatchSaveHelper.BatchSave(WorkItem[] items)--- end Exception entry ---





The Fix for this problem, The Editor doesn't change the other files which use the old values and when the TFS try to create the project it searchs for the old values which is not exist on the updated xml file.

This error usually happens on the "workitems.xml" which conatains a default tasks for each project,if you see the below work item :



Iteration 0"/>







Iteration value is wrong which makes this problem happen when you create new project in the TFS.


You might face the problem with Other customized items on the TFS.


Hope this helps.

when you try to deply AJAX ASP.Net application make sure ofthe following :



1) on IIS,the web site select asp.net 2.0.

2) on IIS,Make sure the Execute Permssion under Home Directory tab is Scripts Only.

3) AJAX Runtime should be installed on the production since it doesn't contains the extedability dlls used by ajax such as System.Web.Extensions.dll.

Enable ATLAS/AJAX on your ASP.Net 2.0 Application

Hi Folks,

In This post i want to change the type of my posts by submitting ASP.NET post instead of long period of TS posts ;),I will describe the steps you need to enable AJAX on an Existing ASP.Net 2.0 application not a new ASP.NET AJAX Enable Application.

In Case you want to enable AJAX on your existing asp.net 2.0 application,first you have to install ajax 1.0 extensions from asp.net website,the download link:
http://ajax.asp.net/default.aspx?tabid=47

Then after install it,do the following steps :

1) Add reference to ajax control kit DLL file to your project "AjaxControlToolkit.dll",you can find it once you install the Toolkit on the Sample Website on the installation path.

2) Very Important : Change your web.config since your project will not work,copy & paste the sections from the existing web.config file.

you can get a sample web.config by creating new ASP.NET AJAX Enabled WebSite.

With above 2 steps,your project will run without any errors,proceed to the following to drag & Drop AJAX Controls visually.

3) On Toolbox window,add new tab,name it AJAX Control.

4) Open the created tab and right click on the tab,and select Choose Items from the context menu.

5) Borwse to the location of "AjaxControlToolkit.dll".

Now,you have all AJAX Controls on the toolbox on VS 2005........... ENJOY !!!!!!!!!!!!!!


NOTE : Script manager should be added on the Top of each page you are using AJAX Controls or you can put it once on Master Page.


Enjoy with building Rich Internet Application RIA :)


This steps is valid only on AJAX v1.0 with VS 2005 ONLY,and doesnt consider using Orcas since it has AJAX as a built in features.

1)TFS proxy server should be installed for every remote office for oyur development team.

2)TFS Proxy installation is different than TFS installation and you can found it in the Proxy folder in the installation DVD.

CacheLimit = (Availble Space + Cache Size)* Percent

Assuming the cache Limit pecent =50 %
The Equation is : CacheLimit = (Availble Space + Cahce Size)* 50/100

6)Cache Cleanup will start to run and free space in the TFS Proxy when :

Available Space is qual to Cache Limit

Delete Project from TFS

Hi Folks,

This post is to how can you delete a project from TFS ?

1) Open C:\Program Files\Microsoft Visual Studio 8\Common7\IDE Folder
2) Open command line and open this path .
3) on the command line write the following command :

TFSDeleteProject /server:YOUR_TFS_SERVER Project_Name

Note :
You must be connected to Team Foundation Server before using TFSDeleteProject.

Use TFSDeleteProject to delete a team project from Team System when the project is no longer needed on the Team Foundation Server.

When you run TFSDeleteProject, the system places the source control data in a deleted state in the operational store. It does not actually remove the data from the database, nor does it reclaim the disk space. Also, the system does not remove the warehouse data originating from the team project.


Hope this helps.

Customzing Process Templete in TFS

Hi Folks,

one of the most important features on Team System is the ability to customize the existing methodologies (Agile & CMMI) and add your own methodology.

To customize the process document; do the following :

1) Download any of the Existing process documents methodologies.
2) Add or delete any docuemtns you dont want;for example (Project Management folder;Requirements folder).

Before uploading your new methodology there's small Tricks :

1) You have to give your methodology a uniques name;O.W. you will get this message "Do you want to overwrite Agile Software Development Methodology" if you download it;this is because this name is taken from ProcessDocument.xml.
You have to edit node in this xml file to your methodology name.

2) Any Documents you will add or remove under Sharepoint services folder, you have to update corresponding xml file "wssTasks.xml" and remove the XML nodes o add your own with the same format on that XML.

HOPE THIS HELPS.

BUG in VS 2003 with MSSCCI 1.2 Provider in TFS

Dear All,

I'd like to share with you a problem on VS 2003 ONLY and not in VS 2005.

The bug as follows; if you install MSSCCI 1.2 Provider for TFS in VS 2003,you can't switch to VSS as a source control.

This problem will affect you because you can't open any project binded to VSS as a source control;it takes TFS as a default source control even if you change it from the TOOL-> Source Control Menu in VS 2003.

NOTE : This problem ONLY exist in VS 2003 and i tried in VS 2005 and its working fine.

I submitted this to VS Product Team as a bug;for now;to solve the problem;you have these options :

1) Either to change in the registry of your machine (I DONT RECOMMEND THAT).
2) Use Third party tools "SCP Selector" , here is the download url :

Arabic Problem when Export Data to Excel

Hi Folks,

I faced a problem when you are trying to export arabic data binded in a datagrid or gridview in asp.net 1.x or 2.0 in VS.Net.

The problem is the arabic data is exported as a un-recognized letters "@@@???#######",since my system is arabic enabled and i can write arabic in my machine.

I checked my code for export to excel,the data is being streamed in a right format but when its appearing in excel it shows as un-recognized letters.

NOTE : YOU HAVE TO CHECK THAT YOUR OFFICE IS SUPPORTING ARABIC BY Open :
START MENU-> OFFICE->OFFICE TOOLS-> LANGUAGE SETTINGS.

The problem exists in office 2003 or even in office 2007.

If you want to see export data to excel in C#,refer to my earlier post :
http://moustafa-arafa.blogspot.com/2007/04/export-more-than-1-grid-in-excel-file.html

The problem wasn't in to put the character set of the response to UTF-8 or Windows-1256,the problem was when Response.End() is called it throw an exception because the thread has been aborted,simply what you have to do is just replace Response.End()
line by below line :

HttpContext.Current.ApplicationInstance.CompleteRequest();

/* FULL CODE TO EXPORT TO SUPPORT ARABIC *************//////

Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";//You can set UTF-8 or windows-1256 but this will not solve
this.EnableViewState = false;
StringWriter oStringWriter = new StringWriter();
HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);

MyDGrid.RenderControl(oHtmlTextWriter);

Response.Write(oStringWriter.ToString());

Response.Flush();
HttpContext.Current.ApplicationInstance.CompleteRequest();

if you used to write this query in sql 2000 db:

select top 5 * from Customers where customerId=110

if you want to do the same with Oracle DB (8i or later),write it like this :

select * from Customers where customerId=110 and rownum<6

rownum<6,do the same of Top 5 and return TOP 5 records

if you have Oracle DB earlier than 8i you have to write the following :

SELECT *
FROM Customers a
WHERE 5 >= (SELECT COUNT(DISTINCT Revenue)
FROM Customers b
WHERE b.Revenue>= a.Revenue)



This is Today Tip,Enjoy .Netting :)

Export Data List to Excel

Hi Folks,

This post is very tricky because it shows a trick about exporting datalist data to excel.

if you have a dtagrid and you want to export its data to excel,by few lines of code you can export its data to an excel file....here is the code :

/******************* BEGIN CODE ***********************************************/
Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.ClearControls(DataGridView);
DataGridView.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.Flush();
Response.End();

/*****************************************************************************/

the important thing here,is to export a datalist which contains a composite controls like a datagrid inside a datalist this code will not work,
simply to solve the problem,comment this line of code in export function :

//this.ClearControls(DataGridView);

then simply all child controls in the datalist will be export to Excel.........


Happy .Netting :)

Problem when uploading large files in asp.net

Dear Folks,

This is an important trick for all web developers and asp.net experts as well,one of my dear firends asked me for a problem he faced when uploading files in asp.net web application,after justify the problem and make sure that the problem not from any other thing,the problem was he was getting [Request Time Out] when he's trying to upload large file size........the solution for this problem is :

.Net Framework by default deny upload any file which exceed than 4mb for a security reason to prohibit denial of service attack.

simply put this attribute on oyur web.config :



maxRequestLenght change the max. size from 4mb to 8mb

you can change it to whatever you want to limit the max file size.
