• Game Technologies: DirectX, XNA, XACT, etc. Mouse Input / Events

  I just downloaded the "Simple Input" tutorial that details steps for handling mouse and keyboard input in XNA GSE. I ran the program and it seems to handle mouse input fairly well. I notice that the mouse "events" are being detected using the Mouse.GetState() method of the Microsoft.Xna.Framework.Input.Mouse class from the XNA framework. The Mouse.GetState() method is being called in the Update method of their custom class InputManager.cs (which inherits/overrides Update() method in Microsoft.Xna.Framework.GameComponent). Questions: Is it possible that the state could change more than once between subsequent calls to Update() For instance if the user clicks the left mouse button quickly. If so is it possib ...Show All

• .NET Development Serialization & Reflection

  Hi All, Do you know that if you serialize, through the automatic .NET serialization mechanism, a class from an assembly named One and try to restore it from the same assembly renamed to Two you get an exception The reason is quite obvious but I am trying to work around to this issue. I mean, if one day I will change the name to one of my DLL the customers will never be able to deserialize their files How can I avoid this Thanks a lot, Alberto Hi Alberto, that wont help either. That enum is used to say how detailed the assembly name will be when serialized. Assembly name is needed to maintain uniqueness of types. The only solution is to ship your data ...Show All

• SQL Server Flat File Connection manager throws error when a column gets added to the flat file

  Hi, I have a situation where a tab limited text file is used to populate a sql server table. The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away  where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS ...Show All

• Visual C++ VS 2005 SE Compiler Errors with VS 6.0 Source Files

  Hello Folks, I recently installed VS 2005 SE and Service Patch 1 to upgrade a Win32 application that was previously compiled with VS 6.0. I tried a raw build to identify the broken code errors and got the expected <strstrea.h> file not found error.

In addition I got a bunch of warnings WINVER not defined.
