  I downloaded the VS Studio Team System Extensiblity Kit and I am using the TeamFoundationServerFactory .GetServer method to get the team foundation server.

• .NET Development Where is mscorcfg.msc(beta 2)?

  I've installed dotnetfx from vwd.img and now I don't know where to find mscorcfg utility.I'm using windows xp(sp2) What's wrong with configuration utilities looks like they are trying to "shed some pounds" from the framework download (since Java is about half the size) i believe that my mscorcfg came with .NET 1.1 which was a critical hotfix for SP2 via WinUpdate - there does not appear to be one associated with the full beta SDK install (2.0.50215)...haven't installed the final release, yet (from 10/27/05) conceivably, you should be able to copy the mscorcfg.msc file from one machine to another (elimin ...Show All

• Windows Forms How to determine if DataGridView rows are accessible?

  Is there  a 100% accurate way to determine if cells of a DataGridView are accessible before trying to access them I have master/detail DataGridViews bound to a dataset. My code, which tries to access cells of the detail grid during SelectionChanges of the master grid sometimes  throws NullReferenceExceptions saying the detail grid columns don't exist. I want to prevent this from happening. I have tried the overly complicated condition below to block access to the detail grid's AuthorID column, when doing so would throw the exception, but it still fails. Also, I would rather not resort to wrapping try/catch b ...Show All

• SQL Server Secure .NET 1.1 application from users

  Hi all. I am developing an distributed VB.NET 1.1 application with a TripleDES capable socket layer for communication with my server app. I need to secure the distributed app from the users within the organization I am developing it for (a franchise). I do not wish to store any encryption keys in the source code as these would be obvious to any seasoned hacker through decompilation of my binaries (even with obfuscation). I have decided to use the windows DPAPI (under machine storage mode) to secure manually entered (at installation) encryption layer keys in the registry. The salt values for this DPAPI mode also need to be secured, ...Show All

• Windows Forms Filtering Parent row values based upon existing child value

  Hello everyone, here's my situation: I have two tables: PURCHASE and PURCHASE_LINE with a one to many relationship between PURCHASE and PURCHASE_LINE. I also have two data grids--one for each table. Both datagrids are bound to the same DataViewManager. Here's my problem: I want the user to be able to filter by items on a purchase, meaning only purchases that contain a certain item in the PURCHASE_LINE table will be displayed. I tried doing this by setting the RowFilter for the PURCHASE_LINE table but this will still allow all purchases to be displayed. I'm at a loss of what to do and any help would be much appreciated! ...Show All

• Windows Forms Refreshing a data source

  I've added a BindingSource control to my form, and set its DataSource to my project data source. When I add fields to a view in the SQL Server 2000 database behind the data source, I can't get the new fields to appear in the view, even if I refresh the data source.

How can I get the data source to refresh I would have to look at the project and Remote Desktop is not behaving nice and i don't feel like logging the user off to get rdc to work. Thank ...Show All
