uWidth

It could fail because the filename passed was incorrect or because the resources passed were incorrect

Example

This code has been taken from the example program, source file SaveAsBitmap.cpp.


//
//	We set a maximum width just to be sure...
const UINT uMaxWidth = 600;
HDC hdcWindow = ::GetDC( hwndParent );
HDC hdcDraw = ::CreateCompatibleDC( hdcWindow );

UINT uHeight = 0;
if( QHTM_GetHTMLHeight( hdcDraw, pcszHTMLFilename, NULL, QHTM_SOURCE_FILENAME, uMaxWidth, &uHeight ) )
{
	//
	//	Now we have a width and a height...
	HGDIOBJ hbmp = ::CreateCompatibleBitmap( hdcWindow, uMaxWidth, uHeight );
	if( hbmp )
	{

		//
		//	Select the bitmap and render the HTML onto it.
		hbmp = ::SelectObject( hdcDraw, hbmp );
		if( QHTM_RenderHTML( hdcDraw, pcszHTMLFilename, NULL, QHTM_SOURCE_FILENAME, uMaxWidth ) )
		{
			//
			//	Deselect the bitmap
			hbmp = ::SelectObject( hdcDraw, hbmp );
			SaveBitmapAsFile( hbmp, pcszBMPFilename );
		}
	}
	(void)::DeleteObject( hbmp );
}

(void)::ReleaseDC( hwndParent, hdcWindow );

(void)::DeleteDC( hdcDraw );
(void)::SetCursor( hOld );
