Hi all,

I start a process using ShellExecuteEx and I get the process handle.

I also need the process ID, how can I get it ?

Thanks in advance,
Dansk.

Good catch, this was an easy one.

More challenging :
How can I get the process Id from its handle on systems prior to winXP sp1 ?

Thanks in advance,
Dansk.

Do you really need to use ShellExecuteEx? If you use CreateProcess, it
returns the process ID as one of the elements of lpProcessInformation.

On NT-based systems use the ZwQueryInformationProcess native API

see: www.catch22.net/tuts/tips2.asp for an example
