Have you tried setPenBkMode(id, OPAQUE) ?
This is supposed to cause the text to use the current background color. Of
course you have to use spaces to clear to end-of-line.

2. RE: Writing text in colors
Thanks for your ideas everyone. I'm not sure I know how to relate the
C++ code to Euphoria and specially Win32Lib. i tried setPenBkMode() but
it doesn't really help. The setWindowBackColor() & setText() combo seems
best as setText writes the whole area, and setWindowBackColor gives me
the background I want. I have reduced the amount I write as a help
measure and so far it looks OK. No getDC... failures in a while, but it
always takes time. ...
Can't help wondering if there is a Windows resource freeing process in
the background that can't keep up if you write too much too quickly?
Anyway, thanks.
