Parameters

hdc

Device context use for drawing.

pcsz

Name of resource, name of file or HTML content. Meaning depends on uSource.

hInst

Instance handle to be used when loading from resources.

uSource

QHTM_SOURCE_TEXT - pcsz is the HTML text to use. hInst is ignored.
QHTM_SOURCE_RESOURCE - pcsz is the name of a resource and hInst is the instance handle to use.
QHTM_SOURCE_FILENAME - pcsz is the name of a file to load. hInst is ignored.

prc

non-zero if it succeeds.

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

Example


//
//	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 );
		const RECT rc = { 0, 0, uMaxWidth, uMacHeight };
		if( QHTM_RenderHTMLRect( hdcDraw, pcszHTMLFilename, NULL, QHTM_SOURCE_FILENAME, &rc ) )
		{
			//
			//	Deselect the bitmap
			hbmp = ::SelectObject( hdcDraw, hbmp );
			SaveBitmapAsFile( hbmp, pcszBMPFilename );
		}
	}
	(void)::DeleteObject( hbmp );
}

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

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