FindWindow function in delphi

Asked by tirbanqs in Delphi Programming

Tags: Borland, Delphi, 6

Hi guys, I have this code:
-----------
procedure TForm1.Button1Click(Sender: TObject);
var
  H: THandle;
begin
  H := FindWindow(nil, 'TestExe');
  if H = 0 then
    //executes a code to popup a form(DLL) in a different handle.

----------
It will check if the 'TestExe' is already running so that it will have a single instance only.
When i close the 'TestExe' then click again the button to popup the form(DLL),
the condition "FindWindow" returns a value greater than 0. So the form will not show anymore...

Any idea on how to do this? Thanks in advanceStart Free Trial
