Shell

[Peter Lameijn]

An asynchronous shell (hShell = Shell ("calc.exe") should return a process handle in hShell if succesfull. But if I pass hShell to GetProcessTimes, I get an error 6 "Invalid handle". Is the returnvalue from shell a Windows process handle?

[Andy Anderson]

No, the return of the Shell function is the instance handle. To get the
process handle try this:


Declare Function OpenProcess Lib "kernel32" _
(ByVal dwDesiredAccess&, ByVal bInheritHandle&, ByVal dwProcessId&) As Long


Y& = SHELL(PATH$, X)

Z& = OpenProcess(PROCESS_QUERY_INFORMATION + PROCESS_TERMINATE, False, Y&)

Thanks! That does it. I now have one other question: how to get the handle of the main window of this process? (I now use findwindow, but that way, if someone starts another instance of the program, I could get the wrong handle...)
