• SQL Server SSAS 2005 Writeback Table

  Hi, there, I have a relational writeback table in my database. I can writeback to the writeback table, but, the date and time in the audit trail (writeback table) is not correct. It is not showing the current date and time when writeback is performed. Any ideas Thank you. Regards, Yong Hwee Hi, Thomas, Thank you for testing the writeback.

• SQL Server Change "Output Alias" on synchronous component programatically

  Wanted to enquire how this is done. Tried doing it in the setUsageType method I have overwritten but only allows description to be changed. Basically need to change "Name". Best option would be to change it instantly when a user selects a column from the inputs in the custom component, ie. it changes the Output Alias to a desired value. (Input tab in advanced editor) All this is being done in a custom component which I would like to be synchronous, can achieve a similar result asynchronously. Thanks If you change the name is setUsageType you see a change in debug mode but eventually it does not change the column name (strangely description can be changed however), basically cha ...Show All

• Visual Studio VS Integration - adding items to project output groups

  Hi all, I've got a simple 'MSBuild project file in VS customization' mission: Two projects (a web project and a class library). Class library references a third-party library consisting of some dlls and some other files which has to be in the same directory as dll files for the library to work correctly. Web project references the class library. Third-party library files has been placed into lib folder of the class library VS project. Because "Copy to output directory" cannot be used on these files (finally they has to be in bin directory, not in bin\lib directory), I've created new ItemGroup called LibFile, put the library files into this ItemGroup and to copy these files to output directory I modified AfterBuild target like thi ...Show All

• Smart Device Development Is DirectDraw supported by Windows CE?

  I have a fast graphics API to support WinMobile 2003+ and I also want to support fast graphics on generic Windows CE devices (non-WinMobile). Should I be using DirectDraw for this If so, should it be provided by the hardware vendor as part of their CE operating system or can i just redistribute DirectDraw on my own. If so, where can I get this redistributable package I'm new to using DirectX. Thanks, George I need to use whatever facility is most portable to all versions of CE. It sounds like GAPI is (although I've heard it was deprecated in favor of DirectX ) Where can I find the best doc on GAPI And as for copying gx.dll, where can i find the portable version of this DLL Is is 100% ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Completely confused

  I recently downloaded XNA and took the video tutorials I could find, but every one of them seemed to have a diffrent version then mine. I found the XNA tutorial microsoft provided, and started following it. Right in the middle of it when I first started coding, it began to get very confusing. His coding was much diffrent then mine, and he was pasting in new coding. I began to fool around with it trying to make it as close to his as I can, but I just got more confused. What are the best tutorials up to date for an complete new person to game designing I recommend watching a few C# videos first to learn how to use the interface and basic programming stuff. Once you have a good grasp on basic C# programming, ...Show All

• Visual Studio AddIn loads only once

  I have written a a small AddIn and packed it up in a .vsi file. When i install the vsi and start the IDE, everything is fine. After Closing and re-opening the IDE, the AddIn Buttons have vanished, but the AddIn still appears in the AddIn manager. Deleting the files under "myDocuments\Visual Studio 2005\Addins", starting the IDE again, closing it and installing the AddIn will bring it back for exactly one run of the IDE. This behavior seems pretty strange to me and i have absolutely no clue whats causing it. Any help is appreciated calavera See my article: INFO: Visual Studio .NET Add-In Commands Disappear On Next Session. http://www.mztools.com/resources_vsnet_addins.htm ...Show All
