RichEdit coloring & hang-up problems

[Sathyadharan]

This app is meant to catch particular "chat line" which contains the few "string(s)" & beeps/flashes once found!

Everything was working fine when i used native edit box. But i wanted to highlight the "chat line" containing the string. So started using richedit control. (few functions were used from the posted forums here.. thnx to them all)

When using the richedit control, i started having few bugs

1. I have to use 3 @CRLF to enter a "blank line" between two lines, except at one place where i need just 2 @CRLF. I duno y.

2. "Randomly" sometimes the Richedit control hangs for a moment. At tht time, "no blank lines" are entered in the richedit between two lines. Samething happens when i hold the vertical or horizontal scroll bar for a while (intentionally preventing the update of richedit) & release it.

3. After working on other windows/apps for a while, and when i shift the focus back to this app, i see tht the whole background color of the richedit control becomes grey & i cannot see any text entered into the control till 1. a new line is entered into richedit programmatically or 2. manually selecting whole of the text of richedit.

4. When i mouse click the richedit control anywhere else except at the default - last character position of the last line ==> the next new line is colored black. This happens only for tht single new line, after tht i see the code running smoothly.

5. "Randomly" sometimes this part of the code malfunctions

for $j=UBound($exploded)-1 to 0 step -1
    if stringinstr($exploded[$j], $oldlasttext)>0 Then
ExitLoop
    EndIf
next

causing $j=-1 at the end of the loop.!!!

Need help.. i tried my best..

thnx
