P/Invoke Problem....

Why does the following cause an EntryPointNotFo undException when I do
ExitWindows(0,0 ); ?

static extern bool ExitWindows(ulo ng dwReserved, uint uReserved);

P/Invoke Problem....

A guess:

"bool" is not the same thing as WIN32 "BOOL". Try
declaring the function as returning an int32...

Because there's no Win32 function called ExitWindows - it's just a
macro defined to call ExitWindowsEx. From Winuser.h:

#define ExitWindows(dwR eserved, Code) ExitWindowsEx(E WX_LOGOFF,
0xFFFFFFFF)

Re: P/Invoke Problem....

Yes, I finally just ended up setting the EntryPoint to ExitWindowsEx and all
was ok.

Sure do wish the sdk documentation would differentiate between macros and
actual functions so that I didn't have to go look at the headers all the
time.

Thanks for the help!
