How to build your DB on MS SQL Azure

Hi Folks,

I would like to share with you some tips for how to move your on-premise DB to MS SQL Azure on the cloud.

First, To be able to connect to SQL Azure Prepare your environment with the following:

1) Install MS SQL 2008 R2 on your machine - Nov CTP, having any other version of SQL 2008 will not give you the full functionality like working with object browser in SQL Server 2008 R2.

Tips :

a) Before installing SQL 2008 R2, please check your exisiting environment by using SQL Server upgrade advisor (it is a part of SQL 2008 R2).

b) Using your credientials in SQL Azure, you will be able to connect using SQL 2008 R2 with no issues and you will be able to navigate through your objects in the DB.

1) How to move your on premise Database to SQL Azure on the cloud:

1) Script your DB from your server.
2) There is some changes you have to do it on the script before executing it on the SQL Azure DB.

Tip: 1) Remove any reference to the file group such as : ON [PRIMARY] on your script.

Then when you remove the reference, you will be able to execute the script using SQL Management Studio and when you refresh the server you will be able to see your new created objects.

Hope this helps.

Cannot open a closed file error in asp.net ajax / SharePoint Site

Hi Folks,

I was developing a webpart in sharepoint ( consider it as a asp.net usercontrol for ASP.Net Developers) and in the webpart i was uploading a document using AsyncFileUpload control in AJAX Toolkit.

And it was working fine, but for some files i was getting this error : "Cannot open a closed file" and i was thinking that the problem from the file or it is a code behind issue.

I figure out the problem was because of the file size threshold in the web.config, the default web.config is:

<httpruntime maxrequestlength="51200" />

I added this attribute:

<httpruntime maxrequestlength="51200" requestLengthDiskThreshold="4096" />

The resolution for the problem is: Set the length disk threshold to 4M ( or any other number in KB as per your application business rule) because by default the value is 80K.

Hope this helps.

Happy SharePointing.... or .Netting :)

If you are trying to open your sharepoint 2007 site one day and you got this error message with yellow asp.net page:

"Retrieving the COM class factory for component with CLSID {BDEADEE2-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa."

The fix for this problem is to do iisreset for your IIS webserver and this will resolve the error.

Installing SharePoint 2010 on Windows 7 Tip

If you are planning to install sharepoint 2010 on Windows 7, here is an excellent article in MSDN, just follow the steps and you will end up successfully installing SharePoint 2010 beta on windows 7.


My Tip is: even if you follow the steps, and run the SharePoint Configuration wizard, the wizard might be failed , what you have to do is just to re-run it and it is going to work. the problem for that when you run in low of memory and the exception is saying failed provisioning central administration website.

Installing SharePoint 2010

Hi Folks,

I'd like to share with all of you how to install SharePoint 2010 on your current platform and to remove any dilemma or milestones you might face or heard from others.

First Question : How can i install SharePoint 2010 on my 32 bit machine ?
Now, you can use either VM Ware Workstation (requires License) or Virtual Box (Free).
Till Today, MS Virtual PC doesn't support to build your 64 bit machine on a your host 32 bit machine.

Now, you don't have any problem to build a VM using either of these software.

I used Virtual Box, and this is my first experience with it, easy and you can use your experience with VPC with it.

[Updated 6/12/09]: VMWare Server is also free, you can try it and its performance is better than Virtual Box.

Once you build and start your VM, here is the steps you have to do:
1- Mount your Windows 2008 R2 64 bit to your VM software.
2- After installing Windows, Install all the updates before start installing the SharePoint 2010.

3- I Prefer to install Office 2010 before installing SharePoint 2010 since you are going to use it with SharePoint.

4- Run Your SharePoint installer and click on install your software prerequisities, this step will go with no errors as mentioned on other posts.

5- The installer will prompt you to run SharePoint Products and configuration wizard, At the end, you will get a failure message : "Failed to create sample data".
FYI: SharePoint is working without installing the hotfix, To download the hotfix:


After installing the hotfix, restart the machine and run the SharePoint configuration wizard again to fix un-provisioned services-WCF.

** Some Other Error cases - Differ from one installation to another:

a) If you got this error :"failed to register sharepoint services", open stsadm tool and type this command:

stsadm -o spsearch -action stop

Then re-run the configuration wizard.

b) If you get this error message :"failed to register sharepoint services- search service" - step 5 in the configuration wizard.

Open the command prompt and type : regedit and navigate to the following key and delete it:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web ServerExtensions\14.0\WSS\Services\Microsoft.SharePoint. Search.Administration.SPSearchService

6- Done, Start exploring your sharepoint 2010 instance.

Hope this helps.

The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again.


"The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again." This error message in sharepoint 2007 you will get it because of different actions you may perform on the site level:

-If you are trying to check out a document in Document library.
-If you are trying to add some columns in a custom list in sharepoint.
-If you are trying to call update() method in the object mode.
-And other actions....

The reason behind this error is when you enable anonymous access to a site with other authentication method such as basic authentication.

The solution or workaround for this problem is to open the central admin, then :
- Select application management.
- Under SharePoint Web Application Management, select Web Application general settings.
- Select your web application first.
- Under web page security validation turn it off.
- Reset your IIS.

Hope this helps.
