I type the following scentence, but it doesn't show 100, but a random number.



DXUTTRACE( "NumFace: %d\n", 100 );

I find some information.



#define DXUTTRACE				  DXUTOutputDebugString

#define DXUTOutputDebugString DXUTOutputDebugStringW



VOID WINAPI DXUTOutputDebugStringW( LPCWSTR strMsg, ... )

{

#if defined(DEBUG) || defined(_DEBUG)

    WCHAR strBuffer[512];

    va_list args;

    va_start(args, strMsg);

    swprintf_s( strBuffer, 512, strMsg, args );

    strBuffer[511] = L'\0';

    va_end(args);

    OutputDebugString( strBuffer );

#else

    UNREFERENCED_PARAMETER( strMsg );

#endif

}

So the function could format message, why do it give wrong result?

What number does it show? Does the number change between runs of your application?

The console maybe joke with me.

How can it compile, if first argument is LPCWSTR, but you are passing LPCSTR ?

Does it work correctly if you call DXUTTRACE at the start of your application? If so, at what point does it go wrong? It's possible that there's stack corruption or similar.

Yes, I think stack corruption exists. the address of args is wrong after va_start().
I can't solve it now.

I have tried a almost empty projection, and invoked DXUTTRACT at the first line in WinMain. But the error is the same as before.
All samples in DXSDK take the same phenomenon.
