Hello there, I'm trying to first count the number of lines in a GUI edit control, and then replace the topmost line if there is over 6 lines.

Here is my code:

Code:
 
gui,submit,nohide
stringreplace,test,status,`r`n,,A
  result := errorlevel
  if result > 6    ; more than 6 lines, out of space, erase the top line
  {
    parsing := status
    status =
    pastfirstline = false
    loop, parse, status             
    {
      if a_loopfield = `n
        pastfirstline = true
      if pastfirstline = true
        status .= a_loopfield
    }
  }


The problem is that the script doesn't seem to recognize `r`n as a new line (so the result is never higher than 6), if I check the script's variable debugger, the result seems to be 0 found each time. I've tried lots of things in place of `r`n but can't seem to get it to work.

Are you sure there is actually a new line character that you are looking for in your Edit control? A normal multi-line edit control will wrap text onto multiple lines, even if there are no newline characters at all in it...

How/why are you limiting to 6 lines (are you trying to for the text to fit on your gui or something like that?)

Nvm I figured it out. I was missing the "UseErrorLevel" switch in the last parameter. And yeah its so I can fit the right amount of messages into a small edit control.

Thanks sin_tax
