How to get CEdit to scroll properly?

Question

I have a CEdit control that's used to display a diagnostics output.
Sometimes the data overflows the screen size, so naturally I set the Vertical Scroll property to true (MFC dialog editor).

But then, when I tried to scroll the text that was in the window before isn't cleared and the new text is written over it.

The result is a big mess of everything I have scrolled past.

I've looked for a draw background property or something similar that will erase everything in the window while scrolling (before redrawing the new data).

Any suggestions?

Answer 1

I think you might want to set Auto VScroll and Multiline to true, and Auto HScroll to false.

Answer 2

I tested this with VS2005, which ships with MFC 8.0. I couldn't replicate your problem.

I added one CEdit and one CRichEditCtrl to a dialog based app. Changed properties Multiline, Auto VSCroll and Vertical Scroll to true. Used SetWindowText-method to put loooooong string of text to both of them. I started the app and text scrolled just fine.

What did you do differently?

Just to be sure. You didn't use the SetCaretPos-method, did you? There was some note about that in the MSDN page. Here's the Knowledge Base article.
