Windows Run

when I type in windows Run window this command: rundll32.exe user32.exe,exitwindows the Win Session is immediately terminated... but the question is:
Can I execute a call in a DLL function with 1 on more arguments???

Ex. rundll32.exe kernel32.dll,_lcreat is a function with 2 arguments: String filename & Long attributes...
What is the syntax of the run command for thi call???

Thanks a lot to all... :)

Declare Function ExitWindows Lib "user32" Alias "ExitWindows" (ByVal dwReserved As Long, ByVal uReturnCode As Long) As Long

Declare Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long

You can find this in the API Text Viewer packaged with VB.

The first one's arguments don't seem very usefull, but you can pass the following uFlags constants to the second function:
Const EWX_LOGOFF = 0
Const EWX_SHUTDOWN = 1
Const EWX_REBOOT = 2
Const EWX_FORCE = 4

Don't know how to type this in the run box though :)

VB Code:

Private Const EWX_LogOff As Long = 0
    Private Const EWX_SHUTDOWN As Long = 1
    Private Const EWX_REBOOT As Long = 2
    Private Const EWX_FORCE As Long = 4
    Private Const EWX_POWEROFF As Long = 8
