Hi!

Maybe it's an easy question, but anyway... how can i run a program when my application starts?

That program could be a com, exe or a batch (.bat) file.

Thank you

Use  WinExec for simple execution:

procedure TForm1.Button1Click(Sender: TObject);
begin
     if (WinExec('C:\Progra~1\GrIP\GripInit.exe', SW_SHOWNORMAL)<32) then
        MessageDlg('You dont have GripInit.exe',mtError,[mbOK],0);
end;

Change to Form Show event if you want the program executed when your program run.

Hope this helps :)

For cobramania:

Hi! Your answer is excellent and i'll evaluate it, but i'd like to ask you something else. How can I run a program with patameters, for example: "arj.exe x archive.arj" ?

Thank you

Hi, try the following:

uses shellapi;
.......
procedure TForm1.Button1Click(Sender: TObject);
begin
     ShellExecute(0, 'open', PChar(arj.exe), pchar('x archive.arj'), nil, SW_NORMAL);
end;

Hi, since i thought you don't need any paramater so i pasted the previous code....
Here's the complete code of mine with the parameter:

procedure TForm1.Button1Click(Sender: TObject);
begin
     if (WinExec('C:\Progra~1\GrIP\GripInit.exe -ge -ke', SW_SHOWNORMAL)<32) then
        MessageDlg('You dont have GripInit.exe',mtError,[mbOK],0);
end;

take a look at the "-ge" and "-ke" parameters

Hope this helps :)

I don't know what operating system you are programming for.
The WinExec function is available just for compatibility to the 16-bit systems!!
To start a program, use - like mentiones before - ShellExecute oder
CrateProcess.
I found out, that ShellExecute is more stabel, when you change the OS.
Running at win9x, Win NT 4.0 won't start the programm and creates an ACCESS_DENIED ERROR
