sorry my mistake

i am using windows XP professional with visual studio 2010 professional
i am using vc++ for developing application.

this is IDL file i use

C#

// File Example1.idl
[
   // A unique identifier that distinguishes this interface from other interfaces.
   uuid(00000001-EAF3-4A7A-A0F2-BCE4C30DA77E),

   // This is version 1.0 of this interface.
   version(1.0)
]
interface Example1 // The interface is named Example1
{
   // A function that takes a zero-terminated string.
   void Output(
      [in, string] const char* szOutput);

   void Output2([out,retval] char *ptrx);

}

Solution 2

problem solved

here is new IDL with changes

C#

void Output(
      [in, string] unsigned char* szOutput,[out,retval,size_is(100)] unsigned char *ptrx);

   void get_file(
        [in,out] long *total , [in,out] long *pack , [out,retval,size_is(5000)] unsigned char* data );
