Hi there!
I use this code to check if an instance is already open but, everytime I click on the program I get a warning about the opened instance but every new instance doesn`t close and it remains opened.

How Can I do to close every new instance?   :o

Many thanks!

`detects if a form is alread open, run it twice to see the effect

Declare findwindow as "FindWindowA" of "user32"
  Classname as string
  Windowname as string
  result as integer
end declare

object myform as form
  center
  caption="myform"
end object

detect

myform.showmodal

sub detect
  findwindow.classname="TForm1"
  findwindow.windowname="myform"
  findwindow.execute
  if findwindow.result>0 then
    showmessage "This window is already open"
  end if
end sub

Something like this??

best regards


Declare findwindow as "FindWindowA" of "user32"
Classname as string
Windowname as string
result as integer
end declare

declare setfocus as "SetForegroundWindow" of user32

Turns out the problem was the SetWinDelay instruction. From the docs: Although a delay of -1 (no delay at all) is allowed, it is recommended.In my case i am calling my applicaton.exe multiple times.I want to check whether another instance is running or not.Could not close the previous instance of this script. Keep Waiting? Hey all, I'm getting this error, and googling it seems to be of no help.
