Hi all,
Anyone using Visual basic dll for interfacing to MT4? How to call it?
Am getting frustated, or is it have to be C++ dll could only run in MT expert / script?
please advise...

Thanks in advance.

vb code (cFunction.cls) -> cFunction.dll

Public Function MergeChar(sFirstChar As String, sSecondChar As String) As String
    MergeChar = sFirstChar & sSecondChar
End Function

mt4 code

  string a;
  string b;
  string c;
   a="one";
   b="two";
   c=MergeChar(a,b);
   Alert(a,":",b,":",c,"working");

I tried visual basic to make a MT compatible DLL but it failed!
I think the only language the MT support is c++.
