• Game Technologies: DirectX, XNA, XACT, etc. Difference between Update() and Draw()?

  This may sound a little basic. Fundamentally, I'd like to know why there are two methods and not just one What would happen if you put all your logic code into the Draw() method for example, or all your drawing code into the Update() method Because GameComponents can change things in each other, and it would be annoying if a component changes something in another gamecomponent that has already drawn what it just changed. ...Show All

• .NET Development [C#]Binary registry values to file...

  Hello, and thanks for taking the time to look at this post... I would like to know if anyone has any suggestions for me as to how I could write the values I pull from the registry, of type binary, to a file using C#. To explain what I am doing, the program creates a file in which it writes all data it pulls from the registry, the keys and the values, in order to create a valid *.reg file that can be kept as a backup for the user. No problems with any other value types so far, the problem with the binary is that it needs to be correctly written in the following format... 00, 00, 00, 01, 00, 00, 00, 01,\ ...adding the comma's and backslash for each line doesnt really come into it, its how do I break down the bytes from the returned byte arra ...Show All

• Visual Studio Team System Mapping a new Team Project to a non-root source control folder

  There are three source control binding options when creating a new Team Project: Create a new root folder $/MyTeamProject Create a new root folder $/MyTeamProject from a branch Do not map source control yet However, if you pick option #3, when you double-click on the Source Control node you're prompted to create, you guessed it, a root folder $/MyTeamProject. Is it possible to map a new Team Project to an existing, non-root source control folder One of our potential customers has a lot of existing source with a specific folder layout, and they aren't very happy about having to change their source layout to this "every team project has a root folder" arrangement.

• Visual Studio Modify WCF Guidance Package

  I need to modify some custom pages in WCF service factory. I installed a copy of service factory code from the installer in sourcecode directory. From other posts in this forum, I understand that I need to change the GUID and manifest file. This may be a stupid question, but do I still need to change the GUID in WCF Guidance Package.xml It looks like the name there is already changed to "CustomWCFGuidancePackage". And besides that, anything else I need to change I just want to make sure my custom package won't corrupt anything in the original one. Thanks! Thanks for the link. I read from Don Smith's blog about recipe runner and he confirmed on Service Factory's forum that it will be available ...Show All

• Visual C++ VC8 CRT merge modules with instanced MSI install

  I've got a unique situation: the installer for our product is MSI based. Having recently switched to VC8, I've been tasked with getting the runtime DLLs included with our install. I've successfully applied the CRT merge modules, however I am having a problem... Our installer is capable of installing multiple instances of our product on the same machine. Suppose I install two instances of the product. Everything works great. As soon as I uninstall the second instance, the first instance is broken because the VC8 CRT was removed from the GAC -- it appears that it wasn't reference counted. I'm wondering what (if any) comments the MSFT folks have on this. Thanks, Aaron Klotz Our problem turned out to be overwr ...Show All
