• Game Technologies: DirectX, XNA, XACT, etc. Decompilable?

  How easily can the games compiled with XNA be decompiled I know .NET and C# can be easily decompiled, so I'm just wondering. Looks like decompiling will not be an issue at first Q: How exactly can I share my 360 game to other 360 users Will my game only be available to people with the XNA “Creators Club” subscription Will it be available to all 360 users that have an Xbox Live account A: There is currently no supported way to share binaries on the Xbox 360. Currently, there are four requirements that must be met in order to share a game targeting Xbox 360 which is developed with XNA Game Studio Express.

• Visual Studio Packages for Express Editions

  I have built the BasicPackage sample and it works great in Visual Studio both with the Experimental hive and full.  I exported the registry keys and tested it both ways and it works great. I then updated the .reg files  and altered them to write out to VCSExpress. VCSExpress is failing to load these giving the infamous "Package Load Failure" message. - I know the dll is registered correctly (it didn't move between the tests) - I know the registry entires are valid (only the base key I write to changed) - I ran "vscexpress.exe /setup" but it returns immediately, unlike devenv.exe - I ran "vscexpress.exe /log" yet it appears to do nothing, unlike devenv.exe   I understand that most of the extensiblity ...Show All

• Visual Studio Express Editions DSN's user ID & password for SQL Server

  Hi, I setup a DSN which uses SQL as data source and chooses "With SQL Server authentication using a login ID and password entered by the user" option. The user ID and password are set in the DSN. I'd like to know how to connect the SQL Server through the DSN (ODBC connection) at runtime, without enter or hard code the user ID and password again as the users shouldn't know the user ID and password of the SQL Server. How to use or get the user ID and password has been set with the DSN Thanks, ybc   Did I say anything about doing that I don't think so. I encrypt the connection string and save the encrypted string. I have several algorithms for doing this including saving an encrypted key in the program and decrypting ...Show All
