Hi Monks,

I'm trying to import a simple messagebox from C# to Perl. To do so I wrapped my C# dll through a C++ code. C# code:

namespace ManagerCSharp
{
    public static class ManagedClassTest
    {
        public static void ShowValue(ref int value)
        {
            DialogResult result = MessageBox.Show("C# Message Box", "C
+# Message Box", MessageBoxButtons.OKCancel);
            if (result == DialogResult.OK)
                value = 1;
            else
                value = 2;
            return;
        }
    }
}

C++ wrapper: 
public ref class CSharpClass
{
public:
    void ShowCSharpMessageBox(int *value)
    {
        ManagerCSharp::ManagedClassTest::ShowValue(*value);
        return;
    }
}

__declspec(dllexport) void __stdcall ShowMessageBox2(int *value)
{
    CSharpClass myCSharp;
    myCSharp.ShowCSharpMessageBox(value);
}

[download]

With this code I was able to call the dll from a C code. But when I try to call from Perl I get this error:

System.IO.FileNotFoundException: Could not load file or assembly 'ManagerCSharp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The specified module could not be found.

in CSharpClass..ctor()

in ShowMessageBox2(Int32* value)

 My Perl code is: 
use strict;
use Win32::API;

Win32::API->Import('ManagedCPP.dll', 'void __stdcall ShowMessageBox2(i
+nt *value);');

my $result;
ShowMessageBox2(\$result);

I have all the relevant files on the same folder.
