getting straight to the point, my program compiles fine.. it shows 0 errors and 0 warnings... but when i run my program, it just crashes.. u know the usual dialog box with buttons like send dont send and debug.. .. here's the code..

}

this is my program.. and i'm pretty sure i'v gone wrong with linking the files or something.. i'v included all the includes and lib files.. is there anything else i need to do.. i remember my professor in college doing something like going to project>settings>links and adding some lib files there like winmm.lib d3dx9.lib etc.. pls help.....

Which version of directx sdk are you using? the most recent ones only support Visual Studio 2005 and above.

i'm using aug 2008 release.. and visual studio 6.. so upgrading to a higher version of vs is the solution??

Perhaps.
You could also add breakpoints in you program to see exactly where (and why) it crashes.

Okay

VS 6.0 has been unsupported for directx development since like 2003. I mean, .NET 2002 and 2003 isnt even supported any more...

Read the section right at the bottom of the page here

http://www.toymaker.info/Games/html/directx_9_0c.html

It has a workaround for the 2004 SDK and Visual Studio 6.

alright.. i downloaded visual studio 2008 express edition... still that above program won't work.. this is what i get when i run the program....

1>------ Build started: Project: initializedx, Configuration: Debug Win32 ------
1>Embedding manifest...
1>The system cannot find the path specified.
1>Project : error PRJ0002 : Error result 1 returned from 'C:\WINDOWS\system32\cmd.exe'.

any help??

Have you registered the paths and environment variables correcltly with visual studio

and how exactly do i do that?? after installing i went to tools>options>VC++ directories and added the dx sdk includes and library files.. i did not do anything apart from this.. do i need to do something else??

Yeah you need to add the path to the directX sdk as an environment variable i think

alright...BINGO!!!...got it to work.. thx a lot jbennet..

was it the environent variable?

I had that issue a while ago trying to get an older version if the DXSDK working with VC#.NET 2003 and NET 1.1. Seems it doesnt always register it properley.
