• Visual Studio Team System Can we ignore files from source control ?

  Hello All ! I'm now having a solution with several DLLs and a web site for which I generate the xml documentation file. By default, when I build all the xml fils are built in the bin folder and are added to the source control. Personnaly, I think that these files should not be in the source control and so I was manually doing an "Undo Pending Changes" on each of these files. Two questions : Is there a way to say to the source control to ignore all the ".xml" file in the bin fodler If these files are stored in the source control, for a reason I cannot explain there is then an error : MSB3021 when I try to build on ...Show All

• Software Development for Windows Vista streamline video/direct3d switching

  My apologies for posting two somewhat related topics so close together. What I am trying to accomplish is a program that plays a video in fullscreen then immediately switches to a full screen direct3d. It will be something like, the video is of a ball moving a certain distance, video ends and program switches to direct3d mode where the user draws a line estimating the distance the ball traveled. I pretty much have these two seperate stages programmed as seperated programs. But my question is how to integrate them. I want the transition to be smooth, which no flickering or obvious changing or switching in and out of video modes. How shou ...Show All

• SQL Server How to change default script generation options in SQL 2005 tools or VS 2005

  Ok, this has been driving me crazy in both SQL Management Studio and VS 2005 Server Explorer. How do you change the default script generation options When I right-click a stored procedure, table, etc. in the SQL Management Studio's Object Explorer, or in the VS 2005 Server Explorer and choose to generate a create script for that object it does not prompt me for any scripting options (like do I want to script dependant objects (where my answer is a resounding NO! but the default that ships with the tools is yes)). I wouldn't mind complaining that I should be able to select multiple items in these tools and generate scripts for all selected ...Show All

• SQL Server Newbie needs help with timestamp calculation

  I'm a newbie, so please be gentle I have a table that has a timestamp column that I can reference, e.g., SELECT * FROM mytable WHERE RECORDTIME < {TS '2006-05-01 00:00:00.000' } This type of selection works.

• Windows Forms WM_QUERYENDSESSION and differences between Win2000 & 2003

  From a locked workstation, if the next user would supply a different set of credentials to login than the user currently logged in, windows prompts you by asking if you would like to logoff the currently logged in user. If you say yes to this and you're in Windows 2000 Server, the WM_QUERYENDSESSION event fires with the lparam set to ENDSESSION_LOGOFF = 0x80000000. If you would do the same thing in Windows 2003 Server, the WM_QUERYENDSESSION event fires but the lparam is set to zero.
