Help Whit Dll import

[Raedon]

Hi all, im a new user of Autoit, usually i use C# but this time y need use Autoit.

I have a question about how to use a Custome DLL made in C#, Here is the code of this DLL

namespace Math
{
    public class AddClass 
    {
        public static long Add(long i, long j) 
        { 
            return (i + j);
        }
    }
}

Now, i saw in the Function Reference of autoit, how to use DLLCall

DllCall ( "dll", "return type", "function" [, "type1", param1 [, "type n", param n]] )

In my case this go this way; DllCall ( "Math", "long", "Add" , "long", "$i" , "long", "$j )

Its this ok? i mean, the sintax? and other think, how i invoke later the Add Function?

Thanks.

You can't do that. DLL that you make will not export any function.

C# compilers compile differently. Code within that dll file needs to be 'interpreted' (wrong term) before you would be able to use it (you need CPU instructions). That is the job of imported function, in your case _CorDllMain from mscoree.dll.

Short version, no exported function = no DllCall() ability

Autoit working on the C++6 Executable file

cdecl

By default, AutoIt uses the 'stdcall' calling method. To use the 'cdecl' method place ':cdecl' after the return type.

DllCall("SQLite.dll", "int:cdecl", "sqlite3_open", "str", $sDatabase_Filename , "long*", 0).

Example Here

Look at the Autoit_RichEditCtrl.cpp

I follow this example on who to export a funtion of a c# dll to use it on c++ proyects

http://www.codeproject.com/KB/dotnet/DllExport.aspx?fid=356836&select=2574834&fr=1#xx2574834xx

Now, how i do to call the Add function prevosly posted??

$result = DllCall ( "Math.dll", "long", "Add" , "long", 5 , "long", 4 )

Thanks.

Could you show Math.dll?
