Not sure. There are probably numerous different approaches. "I've seen more information on a frickin' sticky note!" - Dave Kreskowiak

You could create a GraphicsPath object from the mouse points defining the outline and then use Graphics::SetClip() to set the clipping region to the GraphicsPath in the destination Graphics object before drawing the bitmap.

Or you can use this constructor: Bitmap(HINSTANCE, const WCHAR *) e.g. Gdiplus::Bitmap bitmap(hInst, MAKEINTRESOURCEW(IDB_BITMAP)); Mark -- modified at 0:02 Friday 22nd June, 2007 Fixed Typo "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder

Thanks a lot for helping me so much~:rose:

"The C++ / CLI is for managed and mixed-mode C++ programming only " says the sticky post at the top of the forum. If you read that post, you'll see that it's for exactly what the name says - managed C++ and C++/CLI. This is C++ that uses the .NET framework. The visual C++ forum is for straight C++ questions.

Im not sure but I think I saw like your answer some time ago and I answered to its question with an example(I think it was with CListCtrl) search on the Search comments.:) WhiteSky

Chen-XuNuo wrote: What I want to ask is that when I call the SetPixel function,a dot appear in where I click the mouse,and I want to change the size of the dot. I had a feeling that's what you meant. You can't change the size of a screen pixel. The size of one pixel on the screen is detemined by the video resolution set for the monitor. All the pixels for a given resolution are the same size. That said, you can only go so small. For bigger "dots" you need to draw a cluster of pixels. An easy way to do this is in Windows GDI is to use a pen with a thickness the desired size. I'm not sure what's going wrong with your MoveTo/LineTo code. You'll need to post an example of how you set up the DC and make the calls so we can better help you.
