I am trying to get data from a gui edit box then input a common value at the beginning of every line. The problem I have is that each entry ends with a carriage return, so I end up with a blank line at the end of my list.

Like this.
    server1
    server2
    server3
    -->blank line<--


Her is my code.
Code:
GuiControlGet,servers,,Edit1,
loop, parse, servers, `n, `r
  newservers .= "`n" grid "," a_loopfield ","


This is what I get.
    grid1,server1,
    grid1,server2,
    grid1,server3,
    grid1,,


This is what I want.
    grid1,server1,
    grid1,server2,
    grid1,server3,


How can I get it to ignore or delete a blank line?

Any help?

At this point I would settle for editing the string. I thought I could do it with StringReplace, but I can't figure it out.

you should wait at least a day before bumping your topic. This community is still small enough that there is not always an expert/helper logged in.

Code:

GuiControlGet,servers,,Edit1,
loop, parse, servers, `n, `r
  If (A_LoopField)
    newservers .= "`n" grid "," a_loopfield ","


untested

  newservers .= (( A_Index = 1 ) ? "" : "`n" ) grid "," a_loopfield ","
}
