• Visual Studio 2008 (Pre-release) Why ItemsControl.GroupStyle is ObservableCollection?

  It tried. <ListBox.GroupStyle> <GroupStyle HeaderTemplate="{StaticResource groupingHeaderTemplate}"/> <x:Static Member="GroupStyle.Default"/> </ListBox.GroupStyle> The result seems to use only groupingHeaderTemplate. What is the reason why GroupStyle-Property is ObservableCollection I was not able to find the sample that seemed to become a reason. It is an ObservableCollection so that when you add a GroupStyle, the ListBox gets notified and recomputes the layout with the new GroupStyle taken into account. Many of the samples wouldn't work without this, because the ListBox would never know that there was a new GroupStyle. When you have two GroupStyles in the collection, t ...Show All

I want to create a parameter within the report that is populated by the global list to help filter which work items are returned. Are global lists stored in the SQL database so I can automatically populate the report parameter with the available options The values of global lists will be placed in the data warehouse as the values are used by work items.

• Visual Studio Team System Installing TFS 180 Day trial - SQL schema doesn't match

  I had a working Team Foundation Server Workgroup Edition with TFS SP1 installed. I uninstalled the entire workgroup edition, then tried to install the TFS (RTM) 180 Day trial (not workgroup edition). Now I get an error during install that the SQL database schema doesn't match what is expected ("TFS SQL Server databases exist and their schema does not match the version expected by Setup") and the setup cannot continue. How do I downgrade the database to match what is expected. Or should I try slipstreaming the SP1 install into the 180 RTM trial. I don't know what is causing the problem: 1) Is it because I'm trying to go from Workgroup to the normal edition 2) Or is it due to the fact that I installed SP1, it upgraded the ...Show All

• Architecture Problems with Owner Draw Menus in an out of process ActiveX Document Server

  My Document Server is written with C++ MFC and built using VS .NET 2003 and is targetted to WinXP and newer. I’ve now run out of ideas on how to resolve my owner draw problem when an OLE container attempts to render my shared menus. Everything is fine when the keyboard is used to activate the menubar items. This is because the container is using WM_NCPAINT etc to create a real screen drawing context. This context is then passed through to the in place frame of my server where it will succeed in drawing the menu items ( WM_DRAWITEM ) When the menu bar item is clicked on with the mouse, however, the container make use of WM_PRINT, WM_PRINTCLIENT to render to a memory HDC. When this HDC is passed to my out of process serve ...Show All
