can an indicator execute an external program?

Hi

I'm fairly new to this and I don't know the MT4 limitations.

Can I run an external '.exe' or '.bat' file from within an indicator (or other)??

If so could you point me to an example??

thank you.

See http://forum.mql4.com/16121#109022 and also the link in that post http://support.microsoft.com/kb/238245

I have used ShellExecute successfully many times.

You have every function in the Windows API.

Thank you - that should solve this issue
