    Thanks a bunch! I even asked a bunch of windows programmers at work and no one could tell me how. DotNet programmers seem to only know the interface, not the underlying language anymore...

    Here is my implimentation of the same code.. 
    #! perl -slw
use strict;
use Win32::API;
my $hProcess = getCurrentProcess();
my $cnt=getProcessHandleCount($hProcess);
print "handle count=$cnt\n";

###############
sub getCurrentProcess{
    my $GetCurrentProcess = new Win32::API("Kernel32", "GetCurrentProc
+ess", [], 'N') || return $^E;
    my $hProcess=$GetCurrentProcess->Call();
    return $hProcess;
    }
###############
sub getProcessHandleCount{
    my $hProcess = shift;
    print "hProcess=$hProcess\n";
    my $GetProcessHandleCount = new Win32::API("Kernel32", "GetProcess
+HandleCount", ['N','P'], 'N') || return $^E;
    my $rtn=' 'x12;
    my $ok=$GetProcessHandleCount->Call( $hProcess,$rtn);
    my $count=unpack("II", $rtn);
    return $count;
    }
