Brethern --

Knowing that super search is my friend, I found this node that addresses this very issue.

So I go and download the appropriate DLL referenced in the article and looking at the documentation for Win32::API to import functions from DLLs and come up with the following code: 

use Win32::API;

my $idleTrackerInitHandle = Win32::API->new(
        "C:\\Perl\\dvl\\itunes\\IdleTrac.dll", "int IdleTrackerInit()"
    );
my $result = $idleTrackerInitHandle->Call();


#my $idleTrackerInitHandle = Win32::API->new(
#        "IdleTrac", "int IdleTrackerInit()"
#    );
#my $result = $idleTrackerInitHandle->Call();

#$function = Win32::API->new(
 #     'IdleTrac, 'int idleTrackerInitHandle-()',
 # );
 # $return = $function->Call();

[download]
Where the DLL is in the same dir as the script, in windows/system, windows/system32, etc...

And the result I get is always: Can't call method "Call" on an undefined value at C:\Perl\dvl\itunes\GetIdleTime.pl line 6, <DATA> line 164.

I have never tried importing functions from a DLL before but when I tried the samples on the Win32::API doc pages, those worked fine. I tried the above code and a bunch more (passing parameters, etc) but cannot get it to work.

Does anyone know what I am doing wrong?

Many thanks,
mdog
