No, I'm not sure. There isn't any property to set to change the background color, but you can asign raw RTF to the control using the .SelRTF property. According to the help file, it supports the \cb# RTF code, which changes the background color of text after that code. It doesn't work. It seems to completely ignore it. The \cf# RTF code (Change Foreground) works like a champ.

At this point, I'm ready to scrap the RichText box, and go with ANY other solution that will give me the ability to display text with different foreground and background colors, and allow scrolling up and down through the text, and allow the user to highlight text with the mouse. I'm considering making my own control using picture boxes, etc... Maybe one picture box per letter, or one per background color change on a line, or something like that.. and have code to handle scrolling them with a scroll bar on the right side, making ones at the top disapear with new ones coming in at the bottom... I don't know. It's just raw ideas right now, and I'm afraid it might be too slow.

>>I'm trying to add a line to a RichText box using the .SelRTF property. I've gotton foreground color (\cf#) to work, but I can't seem to make background color (\cb#) to work at all. No matter what I try, the backgroud color of the text added just stays white. Here's the RTF string I'm adding:
>>
>> rtbDisplay.SelRTF = "{\rtf1\ansi" + ;
>> "\deff0\deftab720" + ;
>> "{\fonttbl{\f0\fmodern Fixedsys;}}" + ;
>> "{\colortbl\red0\green0\blue255;\red0\green127\blue0;}" + ;
>> "\cf0\cb1 This is a test\'0D\'0A" + ;
>> "}"
>>
>>It seems to completely ignore the \cb1. And if I use rtbDisplay.SaveFile "c:\temp\temp.rtf", the \cb gets striped out completely. HELP!!! :)
