The PFGAPI is an ActiveX EXE COM object written in Visual Basic 6. As such, it can be used in conjunction
with any programming language that supports COM objects. The examples that will follow
demonstrate using the API functions in VB6. Sample code demonstrating its use in
other programming languages will be available separately.

Subject: Win32::API problems
I am trying to access the method
Connect, in the PGFAPI.exe unsuccessfully.
The code is what follows:
#!/usr/bin/perl
use Win32::API;
use
Win32::Process;
#first I check that I am able to create the
process:
Win32::Process::Create($obj, "C:\\Program
Files\\PFG\\PFGAPI\\PFGAPI.exe",
"pddfg",
0,
NORMAL_PRIORITY_CLASS,
".");
my $pid = $obj->GetProcessID();
print "pid
: $pid\n";
#up here everything works fine. It returns a
PID
#now I try to call the API method
Connect:
$obj = new Win32::API('C:\\Program
Files\\PFG\\PFGAPI\\PFGAPI.exe', 'Connect()', 'PPPPP', 'V');
$answer =
$obj->Call(Ale, 444, 765, 11.123.45.95,
2000);
if(not defined $obj) {print "It is not
working, sorry...";}
The error says:
Can't call method "Call" on an undefined value
at...
Anybody can help? Which can be the reason of not
being able to define the object $obj?
