WIN32::API on .net

[negvon]

When I run this perl code from command line it works

my $in = pack("a150", "A445326990330502736465X161900Q7011150Z07607");

my $res = Win32::API->Import('XYZ32', 'xyz',PPP,N);

my $out = pack("a150", "\0") or die $!;

$res = xyz($in, $out, 0);

print "res = $res\n";
print "out = $out\n";

When I call this small program from .net / C#
it fails

It seems like xyz need to write to $out but fails to access $out memory
We have set full permission and both program run
under user administrator

Hi, welcome to the forums.

This is a tricky one. Do you get any error codes/message when the program fails? anything in the system log?

First, i have tried by convertint the perl with perl2bat
and run the perl as xyz.bat - works
called from C# - no error

Than tried PerlNet, convert it to xyz.exe - works
called from C# got error message that problem to
access $out memory (the xyz.dll is writing back to this var space) . It seems some security issue with .net
We tried to configure all with full permission but didnt helped
