• Game Technologies: DirectX, XNA, XACT, etc. MDX: Assigns a new mesh causes auto Dispose()

  I'm going through the Software skinning method as a learning exercise & I'm at the GenerateSkinnedMesh step, when I had to do this: meshContainer.MeshData.Mesh = newMesh What I'm finding out is that MDX calls Dispose() for the Mesh that's there before assigning the newMesh to it. 1) This is a problem because that Mesh is being kept around in the OriginalMesh property for later use & SHOULD NOT be Dispose'd of, and 2) Is there a way to turn off this behavior If not, MDX is being pretty presumptuous here. This was reported to me recently internally as well, and it's something I'm looking at for th ...Show All

• Visual C# Differneces between c++ and c#!?

  I'm quite new in programing and i started learning c++ but i want to know what are the differences between c++ and c#! (because all examples and learning lessons, from msdn Visual Studio 2005, are written in c#) I know this is a stupid question for all of you but i heard about c# only in Visual Studio. I really need an answer to this question because i don't know what lenguage to learn! Thanks  C# is a newer language with a Java-like syntax and feel to it. C++ is more complex and while much of the syntax is similar to C#, some parts are radically different - I'm thinking especially of C++/CLI vs C# and handli ...Show All

• .NET Development Custom Applicationexception question

  I have just created an exception class with a base class of system.applicationexception.  The question I have is what is the best way to use them. For example, say I had a class to read a csv file, the possible exceptions I could see occuring are 'invalid data','error opening file','Error reading from file'.  I am sure there are more but this will do for this example. Now would I have one exception class that can return all of these errors, and if so how do I diferentiate between them in my catch, or would i have an exception class for each of the possible exceptions with a description related to that occurence ('error reading ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Multiple render targets

  As mentioned in an earlier thread, I'm rendering the results of DrawText operations to textures, and then rendering these textures to the screen. However, I just noticed that this is causing problems when multisampling, making the text corrupted and producing this error message: Direct3D9: (ERROR) :MultiSampleType between DepthStencil Buffer and RenderTarget must match.

• Visual Studio On Demand Report with Push Mode

  Hi I work in Push mode (create a dataset with VS2003 and push this dataset to the Crystal report), with On Demand Subreport, placed in the Detail section of the report. When I click on a Detail Subreport, how is it possible to know the fields identifying the detail corresponding, to be able to seek, in the database, the corresponding data using this identifier (to push them in the on demand subreport) Thanks Hi GGus Maybe what I've done helps you:    1.

• Visual Studio Team System Why doesn't a 'failed' web test 'fail' a load test?

  I setup a simple web test and then added a validation rule on it that said to Fail the test if a certain error message occurred on the page. I ran the web test by itself an it 'failed' due to the error message showing up (I pre-setup the system to always show this error message). I then created a simple load test to run this web test in. I setup the load test to run for 1 minute -- once the load test ran it ran through 20 or so of my transactions -- however, when you view the details for the transactions (or tests) it shows 20 were run and 20 were successful -- no errors were generated at all for this test. I ran the webtest again a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Mesh draw not respecting depth

  Hello! I've created a small sample, drawing a few Box's with the Mesh class, just to get the feeling of DirectX. Unfortunally, the objects that appear on top - being most visible - are the one's that are rendered at the end, and not the one's that are farther away from the camera. Im sure i've missed something, but can't seem to find out what (Guess that's because its such a newbie question... ) Well, thanks for your atention. I can post the code if its of any use. Have you use any of the tutorials as starting point The first 3 tutorials don’t activate the z-buffer. Anyway you should check if you have set EnableAutoDepthStenc ...Show All

• .NET Development XP Home vs XP x64

  I have seen a range of comments here from people with an Athlon 64 processor but only having Windows XP Home installed. First some bad news, Microsoft has EOLed XP Home, they recoment moving to XP Pro or XP Pro x64. x64 was RTM back in Mar 31, 05 so its not quite a year old in the market place, so its not going to be as rich for drivers. I have an Audigy 2 card, drivers for x64 are available, I have a Webcam Live Ultra, drivers are late, Everything else is OK Microsoft's Intelipoint and Intelikey dont work. etc. Games works OK, so moving to x64 is relatively painless for a consumer, but bear in mind, XP x64 is not being promoted ...Show All
