Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

Custom SSIS Data Flow Component Not Showing in Toolbox or GAC

Hello - I have created a very simple data flow component for SSIS (Actually, I am following this example:  http://www.microsoft.com/downloads/details.aspx?familyid=1C2A7DD2-3EC3-4641-9407-A5A337BEA7D3&displaylang=en).  However, when I register the DLL to the GAC, I am unable to find the assembly in C:\Windows\Assembly - even though the GACUTIL says "Assembly Registered Successfully".  Furthermore, after copying the DLL to the PipelineComponents folder for SSIS (C:\Program Files (x86)\Microsoft SQL Server\100\DTS\PipelineComponents), it does not show in the "Choose Items . . ." dialog box of SSIS.   I am running SQL Server 2008 Dev edition, Visual Studio 2010 with .NET 4.0, and Windows 7 Enterprise 64-bit edition.  Any assistance/thoughts would be appreciated. Thanks!

About the Aggregate Function MIN

Hi all, I am using the select statement with MAX(id), MIN(id), COUNT(*) of a very big table and it is returning me the value in less than a second. But surprisingly if i am using aggregate function MIN(id) in a seperate select statement it is taking upto 90 Seconds. Here are the 2 statements I am running SELECT MAX(ID),MIN(ID),COUNT(*) FROM A TABLE  -- Time consuming for this:  less than a Second. SELECT MIN(ID)FROM A TABLE  -- Time consuming for this:  Upto 90 Seconds. Please clarify how it work internally when we call the select statement with Aggregate functions?  chinna

Writing to a custom sink

Hi all,I'm using a modified version of Stephen Toub's secure channel to add compression to the sink along with encryption. Thanks to Stephen I have a very good base to build my sink on and I had no problem adding compression to the sink. Now I want to have compression feature enabled only if the user asks for it. I did'nt know how to send client request to the server. I know that I should write the boolean to the stream on the client side and read it on the server side but it should be done only once.Can anybody show me how or direct me to a sample on the web?Thanks in advance.

SSIS custom task calling web services response errors.

Hi             I have some code within a .Net 3.5 library which call a web service.  The web proxy class was created using WSDL command line tool.  Also the library is wrapped within .Net console, for testing the library works, and SQL Server Integration Services custom task, which is intended to use so that it will be part of the ETL process.    If I run the SSIS custom task and console application on a Windows XP everything works as expected.    However I am currently facing a problem where the response from the web service is not being interpreted correctly when running within the SSIS custom task on windows server 2008 R2, whereas the response from the web service is correctly understood when running the library within console application on the same server.    Has anyone come across this problem before or know any issues with SSIS and .Net libraries which call web services?

Custom SSIS task inteface building issue


Hi all,

I'm tying to use the class foundation that SSIS provides to build interfaces like those of built in tasks

I tried to follow this tutorial


I added a Display text property to my task in order to display it when the task is fired, every thing goes well

except three  issues

1. The display value is not persisted( when I change it from the GUI inteface. It is only persisted if it is updated from the BIDS properties grid)

2. The buttons OK, Cancel, Help are not displayed at the buttom of the interface such in the rest of built in tasks, should I add them programmatically and  if it is the case how  do I to persist properties values when user clicks OK.

3. Some cells in the properties grid shows a combo box like those configuring  connection managers. For example one can expand the combo box and selects <New Connection...>  

Or when one property grid cell get the focus then ellipses button appears when he/she clicks then the OpenDialogResult opens up

Or if one selects some properties grid cells then the properties grid changes by

Reading AND Writing Access 2 databases with SSIS


I went for a job interview this morning, and one of the scenarios that the IT manager (a former programmer) told me about was the following .... If anyone could give me any pointers that I can email him pointers to tomorrow (Wednesday 22nd) it may just help tip his decision in my direction. So there's beer in it if you answer a relevent answer, and I get the job.

Old systems using Access 2 databases. These systems are not due to be updated any time soon.

New systems need access to that data, so each night he exports information using SSIS. However, he needs to also write data back, and more often than just overnight.

However, when he connects to the database, using ODBC connections I think, he says that the app (SSIS) opens the tables / database exclusively, even if he selects the option NOT to open it exclusively.

Any ideas, suggestions or comments ?
