'AntiXssLibrary' or one of its dependencies. There is not enough space on the disk. (Exception from HRESULT: 0x80070070)

Hi Folks,

If you got the error message from MS CRM 4.0 which is running on a VM on your test or production Hyper-V manager server, After i checked the the error message on the server, the error message which was :

"'AntiXssLibrary' or one of its dependencies. There is not enough space on the disk. (Exception from HRESULT: 0x80070070)"

Just trun off your VM, Then expand desk space allocated for the VM will fix the issue.

Hope this tip helps.

Access denied when try to sign your project in VS 2008

Hi Folks,

If you are facing a problem that you can't sign your project using VS 2008, this is not because there is a problem in VS 2008 but this is because the User Access control (UAC) feature in Vista. The User Access Control enabled in your system, you have to disable it to enable signing to your assembly in VS 2008.

OR

If you can't publish your project using ClickOnce deployment in VS 2008 and your are getting an error message : "publish aborted, can't create a default certificate"

The cause for above 2 errors messages are because of the UAC is enabled.

To do/fix this:
1) Open Run windows in Vista: Accessories -> Run.
2) Type MSCONFIG command.
3) select tools tab, select Disable UAC and click on Luanch button.
4) Reboot your system (Important).

Once you reboot your system, open your project and you will be able to sign your assembly.

Hope it helps.

My first SQL azure Application on the Cloud !!!

Hi Folks,

Few months ago, i worked with Azure Services, and since i'm interested to develop applications over the cloud which extensively use SQL Server as a backend, i used BLOBS to store my data... actually it wasn't that easy to use, but the product was still in beta in that time.

Recently, I have some time to develop and start using SQL Azure services, A big start by allowing us to create the Database over the website, then all other operations ( CRUD ) for the Database design and object model can be done using ADO.Net classes.

C# Code for connecting and creating a table over the cloud:

SqlConnectionStringBuilder connString2Builder;
connString2Builder = new SqlConnectionStringBuilder();
connString2Builder.DataSource = "MyServer.ctp.database.windows.net"; // check your profile to know server name.
connString2Builder.InitialCatalog = "YourDB"; // you can create your own their.
connString2Builder.Encrypt = true;
connString2Builder.TrustServerCertificate = true;
connString2Builder.UserID = "myUserName";
connString2Builder.Password = "myPassword";

// Connect to the sample database and perform various operations
using (SqlConnection conn = new SqlConnection(connString2Builder.ToString()))
{
using (SqlCommand command = conn.CreateCommand())
{
conn.Open();

// Create a table
command.CommandText = "CREATE TABLE MostafaTable(Col1 int primary key, Col2 varchar(20))";
command.ExecuteNonQuery();

// Insert sample records
command.CommandText = "INSERT INTO MostafaTable(col1, col2) values (1, 'string 1'), (2, 'string 2'), (3, 'string 3')";
int rowsAdded = command.ExecuteNonQuery();

// Query the table and print the results
command.CommandText = "SELECT * FROM MostafaTable";

using (SqlDataReader reader = command.ExecuteReader())
{
// Loop over the results
while (reader.Read())
{
Console.WriteLine("Col1: {0}, Col2: {1}",
reader["Col1"].ToString().Trim(),
reader["Col2"].ToString().Trim());
}
}
}
}

SortedSet <T> new collection type in .Net 4.0 beta 1

Hi folks,

This post based on my readings in .Net 4.0 beta 1, one of the new enhancements in .Net 4.0 is SortedSet<T> collection type, which implements red-black sorting algorithm with complexity O(log n) for the entire list.

Red-Black tree is an efficient sorting algorithm and using this collection will help alot from performance of sorting large sets in the run time.

C# code:

var mySet=new SortedSet <int>() {3,2,7,23,12,879,345,122,98};
foreach(int x in mySet)
{
Console.WriteLine(x);
}

// output: sorted list.

Exception when implement function overloading in WCF

Hi Folks,

If you tried to develop a simple WCF function, and you tried to write in your WCF 2 overloading functions in WCF, you will not be able to deploy your serivce and the clients will get an exceptions.

The solution: give Aliases to the overloaded functions in the WCF service.

Code :


public interface IMyWCFSvc
{
[OperationContract(Name="GetCustomerById")]
string GetCustomerInfo( int CustId);

[OperationContract(Name="GetCustomerByEmail")]
string GetCustomerInfo( string CustomerEmail);
}

The proxy when you reference to your serivce, will create 2 methods with the Alias names and not with the actual overloaded name in C# code.

Hope this helps.

Error when trying to connect to or download PerformancePoint designer

Hi all,

I was getting an error message when i'm trying to connect to Performance point server, and the error message wasn't descriptive at all, this is the error message :

" ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of http://ServerName/DesignerInstall/ resulted in exception. Following failure messages were detected: + Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
COMPONENT STORE TRANSACTION FAILURE SUMMARY No transaction error was detected.
"
If you don't have performance point server on your machine and you are not able to download it below shows how can you do this.

To do this, get the download from your server, this is the path:

C:\Program Files\Microsoft Office PerformancePoint Server\3.0\Monitoring\DesignerInstall

Take 3.0 folder, and install the designer on your desktop.

After installation, you will have another problem, you can't connect to your server because you didn't install it from the browser, to fix this do the following:














Replace localhost:4000 with your server name and click ok.

Then you can click on Refresh to get all the contenct on your designer.

Hope it helps.

How to control which Silverlight version does your application run on ?

Hi Folks,

I have been asked from one of my colleagues that he developed a Silverlight 2.0 and he doesn't want to upgrade his application to Silverlight 3.0.

To control which Silverlight version your application will run on: simply open the page which contains the Silverlight object (default.htm or default.aspx) and check the Silverlight object, you will find the following:

- minRuntimeVersion: used to control the version of the Silverlight that your application will run on at minimum.

For example: if you built your application on version 2.0, the client will not be prompted to install version 3.0 when visiting your website if he has version 2.0 and this attribute is set to use version 3.0.

autoUpgrade: when it is true, the application will be upgraded to the newest Silverlight version automatically. If it is false, noting will happen.

Some use cases for different situation:

- - Before shipping your application make sure that make autoUpgrade to false, unless you developed some features which requires the client to upgrade his Silverlight version to the newest one.

- - Set the value of minRuntimeVersion to the version you test your application on, and make sure this is the minimum version you want to make your application is running with no issues.
