I have written two applications in Delphi 5.0 and I need to have one of them launching the other if certain conditions are met inside the program. How can I do this?

Thanks a lot in advance !!!

hello,

you should use code below. this code executes your app. SW_Shownormal is the parameter about your app. window.

Well you could use ShellExecute or CreateProcess methods for special situations (i.e. you should create a process if you want to have control on the execution of the program you've ran - even find if it's continuing or when it ends etc) but winexec is cool if it's enough, because it's practical.

cheers !!!

var
apppath:string
success:boolean;

   apppath:='c:\myotherapp.exe';

   if fileexists(apppath) then
      begin
        success:=WinExec(PChar(dosya),  SW_SHOWNORMAL);
        if (success<>0) and (success<>ERROR_BAD_FORMAT) and (success<>ERROR_FILE_NOT_FOUND) and                         (success<>ERROR_PATH_NOT_FOUND) then
          begin
            // ok, my app did execute
          end
        else
          begin
            if success=0 then
               Showmessage('')
            else
               Showmessage('error= '+inttostr(int64(success)));
          end;
      end //if filexistz
   else
      Showmessage('apppath is not valid');

well, everyone has an answer, no? sorry because there's a small mistake in mine: the "dosya" is to be "apppath"
