my code will not enter this if statement for some reason if (SUCCEEDED (IDirect3DDevice9_UpdateSurface( pDirect3DDevice, lpD3DRenderTarget , NULL, lpD3DTempSurface,NULL))) { }


	LPDIRECT3DSURFACE9	lpD3DRenderTarget = NULL;
	LPDIRECT3DSURFACE9	lpD3DTempSurface = NULL;
	D3DLOCKED_RECT		d3dLockedRect;
	D3DSURFACE_DESC		d3dDesc;
	LPDIRECT3DSURFACE9 lpD3DFrontBuffer = NULL;

IDirect3DDevice9_GetRenderTarget( pDirect3DDevice, 0, &lpD3DRenderTarget );

if (SUCCEEDED( IDirect3DSurface9_GetDesc( lpD3DRenderTarget, &d3dDesc )))
{
IDirect3DDevice9_CreateOffscreenPlainSurface( pDirect3DDevice, d3dDesc.Width, d3dDesc.Height,D3DFMT_A8R8G8B8, D3DPOOL_SCRATCH, &lpD3DTempSurface, NULL);

    if (SUCCEEDED (IDirect3DDevice9_UpdateSurface( pDirect3DDevice, lpD3DRenderTarget , NULL, lpD3DTempSurface,NULL)))
    {
    }
}

Install the debug runtimes and read the Documentation, and you'll find out that:

Quote:
This function has the following restrictions.
The source surface must have been created with D3DPOOL_SYSTEMMEM.
The destination surface must have been created with D3DPOOL_DEFAULT.

You probably want StretchRect, and you'll want the temp surface in D3DPOOL_DEFAULT.

when i do

IDirect3DDevice9_GetRenderTarget( pDirect3DDevice, 0, &lpD3DRenderTarget );if (SUCCEEDED( IDirect3DSurface9_GetDesc( lpD3DRenderTarget, &d3dDesc ))){IDirect3DDevice9_CreateOffscreenPlainSurface( pDirect3DDevice, d3dDesc.Width, d3dDesc.Height,D3DFMT_A8R8G8B8, D3DPOOL_DEFAULT, &lpD3DTempSurface, NULL);   if (SUCCEEDED (IDirect3DDevice9_StretchRect(pDirect3DDevice,lpD3DRenderTarget,NULL,lpD3DTempSurface,NULL,0)))    {    }}

i get the same , not going into the

if (SUCCEEDED (IDirect3DDevice9_StretchRect(pDirect3DDevice,lpD3DRenderTarget,NULL,lpD3DTempSurface,NULL,0)))
{
}

if statement

That'll give you useful debug output, telling you what's wrong. Also, what is the return value? Checking with SUCCEEDED narrows it down to one of 2 billion (Well, 2,147,483,647) possible error codes...
