Add-In with Perl (perlctrl)

[Danor]

Hello,
I'm working with EA 9.3 and would like to create a Add-In based on Perl. With perlctrl (I've got the PerlDevKit) I'm able to create a .dll out of my perl code.

Up to now I've created a file which contains a EA_Connect function and created me a .dll file. Registered it and added an entry in the EA  egistry, so that EA finds it. Unfortunately EA won't start up anymore, unless I delete the registry entry again. Any idea what I could have done wrong ?

Looking forward for some help   Thanks

the EA_Connect function :

Code: [Select]

sub EA_Connect {
  my $repo = $_[0];
  return "";
}

the method declaration for perlctrl:

Code: [Select]

...
EA_Connect => {
RetType             =>  VT_BSTR,
TotalParams         =>  3,
NumOptionalParams   =>  3,
ParamList           =>[ ParamName1 => VT_DISPATCH,
ParamName2 => VT_BSTR,
ParamName3 => VT_BSTR],
},
...

the perctrl call :
perctrl myadd.pl
what creates a myadd.dll . Maybe I've missed some important settings ?

I'm no perl expert, but have a look at this thread: http://www.sparxsystems.com/cgi-bin/yabb/YaBB.cgi?num=1364378966. Honestly though perl and java are very different, I doubt you'll get this working.

Best regards,
Günther

Thanks for the replies.

I got your perl plugin. I first added the dll file which comes with it, what worked without problems.
Second I created a new dll out of the EaControl, after registering this I have the old Problem ? Do you have an idea what I could have done wrong ?

Not really. You need to put in lots of print statements (write to a file) in order to find out where the bug is buried.
