• Software Development for Windows Vista Drivers signing question.

  Hi all! My product installs a boot-start filter-driver, but uses co-installer for its setup. I have successfully signed this driver using MS recommendations, but I have a number of questions and I would be very happy if someone could help me clarify them: 1. For LOGO certification - is it obligatory to install filter-driver through .inf file or I can use co-installer 2. Shall I generate .inf and .cat files if I use 'co-installer' way 3. MS docs say that .cat files must be signed with a cross-certificate. But what about .sys-files inside the driver package What certificate should I use - from Verisign or the cross-certificate 4. In case of '.inf-file' installation scheme, are the sign rules similar for device drivers and for filter-drivers ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Trends in Managed Game Development

  Hello all I'm just starting developing games and am wondering which language / envirronment to write them in. At the moment for experimenting using Direct3D I'm using C#, with Visual Studio 2005 (.NET), and mucking around with DirectX 9, and XNA (the XNA game studio express). I've always figured that the professional game devs use unmanaged C++, but is that changing now with the additional support for managed DirectX So, in short: If I want to make a game using DirectX, what language / environment should I use to make it Thanks =) -Cabbeh Lots of game shops use Visual C++ and Visual Studio. Don't let the .NET scare ya, it's still plenty easy to crank out unmanaged c ...Show All

• .NET Development Best/fastest way to save a large DataTable a database?

  Hey, Whats the best way to save a rather large DataTable to a database It consists of roughly 60 columns and 15 thousand records (6MB of raw text).

• SQL Server Date Range filter

  Hi guys, I need to filter result in MDX query by passed Start Date and EndDate I come up with following solution Without specifics on what you're doing, it's hard to suggest a specific course of action. (What is the full query, what tool, etc.). Some suggestions on how to proceed: Validate that your filter "set" is in fact correct. I'd look at the the specifics behind the selection, date formatting, etc to ensure it's still being properly parse. Try (in the MDX) creatng a dynamic set, then referencing the set in the where statement. At a minimum, it'll make what you're trying to do easier to understand and test. Depending on your front end tool, consider putting the "WHERE" into the pages (axis 2 ...Show All

• Visual Studio Team System Sharepoint sites for TFS disappeared

  Hi Today I noticed a big problem with our TFS test server, the SharePoint sites for all the team projects are gone. The sharepoint sites haven't been visited for a few weeks due to the summer holidays, but they were certainly not deleted on purpose. This is not a big problem however, as these were only sample sites. The big problem is that it's not possible to create new team projects, I have tried both repairing and reinstalling SharePoint, but this doesn't seem to help. I would prefer not to set up everything all over again, so if anyone can help me get back on track I'd be very happy. Would you be able to post the error that you are getting on project creation from the logs Also - shot in the dark this one, but could one of th ...Show All

• Visual C++ atof rounding error

  Hello, While using visual studio 2005 I noticed an odd rounding error where 0.0355 gets converted to 0.0349 when atof("0.0355") * 100000.0 is done.
