Screen Shot

again :-)

HRESULT hr;
IDirect3DSurface9* screenshot; 

hr =  pDevice->CreateRenderTarget(			 		
                                 oDirectX9.GetBackBufferWidth(),
                                 oDirectX9.GetBackBufferHeight(),
                                 oDirectX9.GetBackBufferFormat(),
                                 D3DMULTISAMPLE_NONE,
                                 0,
                                 false,				
			         &screenshot,			
	 	                 NULL						
                                 );


hr = pDevice->GetRenderTarget( 
				1,
                                 &screenshot				
			     );


hr = D3DXSaveSurfaceToFile( ".\\shot.bmp", D3DXIFF_BMP, 
                               screenshot, NULL, NULL );

SAFE_RELEASE( screenshot );

Maybe another ".", I don't know anything about dx so thats my only guess. N/M I have a second guess, shouldn't you be allocating the surface somewhere? You declare it then you just start using it it looks like. Maybe the createrendertarget function is how you allocate it? What does is that function actualy doing?

Is this all the code in this area?

edit: hmm, your second post looks better, does it work now?

Hey here''s a code which i found and works:

SaveScreenShot( char *fileName, _D3DXIMAGE_FILEFORMAT ImgFormat)
{
	HRESULT hr;	
	
	//The front buffer used to get the screenshot	
	LPDIRECT3DSURFACE9 buffer = NULL; 
	
	
	// Create a surface for the screenshot to be rendered to	
	if( FAILED( hr = mpD3DDevice->CreateOffscreenPlainSurface( 
		mD3DPParameters.BackBufferWidth,
		mD3DPParameters.BackBufferHeight,	
		D3DFMT_A8R8G8B8, D3DPOOL_SCRATCH, &buffer, NULL ) ) )		
		return false;	
	
	// Write the front buffer to the surface 	
	if( FAILED( hr = mpD3DDevice->GetFrontBufferData( 0, buffer ) ) )
		{			
			mGCLog.Error("Cannot Acquire front buffer...");			
			buffer->Release();			
			
			return false;		
		}	
				
	D3DXSaveSurfaceToFile( fileName, ImgFormat, buffer, NULL, NULL );	
	
	// Cleanup	
	buffer->Release();		
	return true;
}
 

hope it helps!

It may be overkill if you''ve got your method sorted out by now, but:
Designing a Screen Shot System (here on GDnet)

also,
Sweet Snippets: Generating a Screenshot in DirectX 8.1 (also here on GDnet; I know it''s for DX8.1, but it may still be applicable)

Helo

Thank you very much for help. DivineLight code seem to work, but
I can only get a totaly black screen shot or some pixel mess
if I use D3DPOOL_DEFAULT insted of SCRETCH. I tryed everything and
I still get totaly black picture.

Any ideas?

D3DXSaveSurfaceToFile will fail because D3DX cannot lock nondynamic surfaces located in video memory?
try making the surface dynamic
