Re: Import a DLL from C# to Perl

With this code I was able to call the dll from a C code

There are a couple of alternative approaches you could consider.
If you can achieve what you want in C code, then you should be able do the same in Perl, using Inline::C.
OTOH, if the wrapper code that you have is C++, then maybe Inline::CPP would be better.

If this is just about utilizing user32.dll's MessageBoxA function, then the Inline::C cookbook contains this example.

I've nothing against Win32::API - it's just that I've never managed to bring myself to persevere with it.
I'm therefore unable to provide any help with that particular module.

Cheers,
Rob

If this is just about utilizing user32.dll's MessageBoxA function, then the Inline::C cookbook contains this example. Win32 can also do that: `use Win32;; Win32::MsgBox( "Hi, from perl\nWhat can I do for you today?", MB_ICONQ +UESTION );;` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

I tried using Inline::C and Inline::CPP and I get the same result. Looks like Perl doesn't have access to something from the C# enviroment. And it is not about the MessageBox, I'm just using it as an example.	[reply]

I tried using Inline::C and Inline::CPP and I get the same result According to what I found on StackOverflow the error is simply that a file cannot be found. When you run the perl script, is it running in the exact same shell that successfully runs the C/C#/C++ programs ? I'm thinking that the success you experience with the C/C#/C++ programs will depend upon certain environment variables being set correctly ... and that the failure you experience when running the perl script arises because one or more of those environment variables is no longer set (or has been altered).

No, not the same shell. My C++ and C# code were build with VS. The C code that I could run as a test I used DEV-C++.	[reply]
