You can find the source as part of this post here: http://www.codemonkeycodes.com/2010/01/11/ithumbnailprovider-re-visited/

It doesn’t have the source for the PreviewPane though, if you need that, let me know and I’ll see what I can do.

Hi Jeremy,

I am a newbie to Win Prog. I am trying to create a thumbnail and preview for a Custom doc as a part of my project. I was wondering if you could share your Ithumbnailprovider Impl. Would be really helpful. TIA.

Paul, I’m glad you ( and Dan ) found this helpful. It really pleases me that people are still finding this article helpful even a year after I wrote it

Thanks Jeremy! After trying numerous samples to try and get this to work, yours was the first one that actually did – and was very easy to use to boot!

One thing to note for people trying to use this, if it works the result is a completely blank icon (instead of the default blank page icon). I think it was you and Dan having a conversation on another page I found, and a slight variation on your suggested “Hello World” implementation of GetThumbnail is this:

*phbmp = NULL; *pdwAlpha = WTSAT_UNKNOWN;


	ULONG_PTR token;

	GdiplusStartupInput input;

	if (Ok == GdiplusStartup(&token, &input, NULL))

	{

		//gcImage.LogBuffer();

		Bitmap * pBitmap = new Bitmap(188, 141);

		if( pBitmap )

		{

			Graphics xGraphics( pBitmap );

			Font xFont( L"Arial", 12, FontStyleRegular, UnitPoint );

			SolidBrush xBrush( Color( 0, 0, 0) );

			xGraphics.DrawString(L"Hello!", 6, &xFont, PointF(0.0f,0.0f), &xBrush );

			Color color(255, 0, 0);

			pBitmap->GetHBITMAP(color, phbmp);

		}

	}
	GdiplusShutdown(token);
	if( *phbmp != NULL )

		return NOERROR;

return E_NOTIMPL;

Not forgetting to add #include “Gdiplus.h” and link to “gdiplus.lib”.

Interestingly, Dan works at the same company as myself, and sits a few desks away – yet we discovered this page separately and for different purposes.

Ralfn,

Have you tried this on Windows 7? According to Microsoft, it “shouldn’t be written managed”. When is it you set your IStream to null?

I successfully implemented a ThumbnailProvider in C# by setting all references to IStream to null and calling GC.Collect after the image has been gathered from the stream. Works like a charm.

Hi Jeremy,

Congratulations on sticking with P90x. I tried that…and I lasted 3 days, but I swear I may get back into it. Hmm..I am also 30 something and divorced and a geek…but I did play D&D when I was a teen…and I totally would play it again if I had the chance But alas I am too too busy.
