RichEdit background

Does anyone know if it is possible to put a background image behind a RichEdit control or a CRichEditView derived window.
I know how to change the background color, but need to place a bitmap behind the control.  Do I need the bitmap in a window behind the RichEdit one?

I need to make it look like the text is being typed over an image.

Unfortunately, that won't work. If you're using CRichEditView, you're using RichEdit 1.0.  RichEdit 1.0 doesn't draw transparent text. You can't handle it's erase background, and you can't subclass it's painting to convince it to do so.

You're just out of luck.

RichEdit 2.0 can help you do what you want, but it is not yet supported by MFC.

I tried that, I also tried overriding OnDraw, OnPaint, neither work.  I'll look more into RichEdit 2.0. Thanks

You'll find that you can simply override PreCreateWindow or Create to have it create the new class.  You'll also need to loadlibrary RICHEDIT20 instead of calling AfxInitRichEdit().

Depending on how aggressively you use the class, thogh, you might need to do more than override the creation and hcange the initialization--it's possible that you'll need to start from scratch. This much work can make the notion of haivng a background bitmap a little bit too expensive--and you you might want to reconsider that feature for your application.
