Hello,

I am trying to use Pinvoke to use a Win 32 Visual C++ 6.0 dll in a .net
C# application.

This is the original function signature.


BOOL __stdcall GetXMLString(
       const char* strInputFileName,
       const char* strPassword,
       char* strOutput,
       char* strErrorMessage)


  This is the signature i am using :


[DllImport("C:\\STLKit.dll", CharSet = CharSet.Ansi)]
    public static extern bool GetXMLString(
              [In][MarshalAs(UnmanagedType.LPTStr)]string
strInputFileName,
              [In][MarshalAs(UnmanagedType.LPTStr)]string strPassword,
              StringBuilder strOutput,
              StringBuilder strErrorMessage);


The problem is that ONLY the first character of the string
strInputFileName is being passed to the function.
Do I need to allocate memory for the strInputFileName ?


Any response would be highly appreciated.


Thanks,
Anirudh

Get rid of the attributes, you don't need them and in this case the
MarshalAs is incorrect.
