• .NET Development Simple problem with retrieving data

• Visual Basic Word border problem (declaration

  I want to set: WordApp.Selection.Borders = wdBorderBottom But problem is, that it says that wdBorderBottom is not declared. How can I declare it where are you obtaining the code from Of course if you get an error stating that the variable is not declared, then you need to declare it of course in order for it to work but I am guessing (unsure) that you are using COM Interop to access Word instance If so, you need to give it the correct parameters/properties/values etc... would help if you can supply where you are obtaining the code from so we can help ...Show All

• Visual Studio 2008 (Pre-release) linq ready for production??

Is there a version of LINQ that works appropiartly with C# 2.0 And is LINQ ready to be used in a huge project or it is yet just a CTP Best Regards Joseph AFAIK C# 3.0 Language constructions are base of LINQ so you cannot use LINQ with C ...Show All

• SQL Server Incremental update of dimension?

  With the fact table one can use the "process incremental" option to add new factdata without having access to all the old data. Is it possible to do something similar with dimensions I.e. add new dimension members without having to store all the old ones for rereading with "process update" The process option UI and documentation seems to agree that it can't be done. However a quick googling found some microsoft paper promising incremental updates to dimensions as well, leaving me slightly confused. Thanks - that was exactly what I was looking for. Oddly enough the options mentioned in your document doesn't correspond to those in the help here: http://msdn2.microsoft.com/en-us/library/m ...Show All

• Visual Basic DateTimePicker

  I want to add a date time picker to a toolbar. What is the best way. I know I can just drop it on there, but it would cover up everything else I add to the toolbar Thanks Brian Hi, I think you may try to put a Button in the Toolbar, and put a Calendar control invisible. After the user click the button, you can show the calendar control. If you still have any concern, please feel free to post here. Best regards, Peter Huang ...Show All

We a have a standby/readonly DB from logshipping for hot standby and we would like to make a copy of this standby/readonly DB into a read/write DB in the same server for daily testing. Thanks in advance! Now I see the issue at hand here, sorry. Because of the "slave" database's state in your log shipping topology you cannot perform a backup. I will research if someone else doesnt have a quick answer for you. Derek ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Vista Compatibility

  Looking for any hints on when a Vista version will be released. (Note that I'm in the middle of installing the same version as everyone else is right now, but the web site says it won't be out for a bit). I really don't want to put a third OS on my system just so I can run xna express. (I've already got Vista Ultimate 32 and 64 bit on here - starting to get crowded) Dan The compatibility issues are due to VS compatibility so if you get VS SP1 and the VS Vista patch (in beta) then a lot of us are sucessfully running on Vista. The only problem I am seeing is the the VS Version selector app (which is what is run when you open a .sln file) doesn't work at all and I am having to open VS and ...Show All

• Visual C# Task List Comments in Closed Documents

  Hello I have flaged several lines of code with the TODO marker. The problem is that they dont show up in the task list unless the document is open, is there a way to view all tasks even if the document is closed   -Jacob Blumberg TaylorMichaelL wrote: The desired feature has not been added as of Orcas beta 1. Therefore you probably won't see it until post-Orcas. Still it isn't rocket science. You could create a simple add-in to do the same thing. The biggest issue (beyond parsing the various source languages) is keeping the task list in sync with the files. If the file isn't open in the editor then file modifications aren't tracked (that is a good th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. persistent backbuffer OR renderTarget (on 360) possible?

  I want to disable backbuffer clear. Though I have removed the Clear from my draw func it still gets cleared to black on Xbox360. Run the same thing on PC and the mystery clear doesn't happen (stuff I'm drawing correctly smears across the screen). I also tried to workaround w/ ResolveBackBuffer to a texture and draw this back at the beginning of each frame but thats not working for me either. In this case my Draw() looks like: Draw Backing Texture using Quad Draw new items ResolveBackBuffer -> Backing Texture I even tried double buffering the backing texture w/ no luck. Thirdly, I tried RenderTargets, but they also seemed to be getting cleared each frame as well! I would think there's gotta be a way for rendertarget contents ...Show All
