Call VB ActiveX dll from C language

The scenario is simple - a screen displays a list of data. Click an item on the list to display an scanned image. A document id is passed to determine which image to display. IBM imaging software displays the image.

Problem is: IBM imaging software uses ActiveX VB dll to display image and screen is written in J. D. Edwards which is a low level C language, so I must call the VB dll from C language. I'm using MS Studio 6. I wonder if this is possible?????

I have the following so far. When I click the screen, it goes through the program and does nothing. I have tried to debug this by adding some dll's into the Program Settings with no success. A window pops up showing the Disassembly, breakpoints are not recognized and I can't display any field values.

Any help is very much appreciated ... Jim

// code from header

#include <windows.h>
typedef (*PFNJDE2CM)( LPCSTR ); // VB dll to call receives one string parm

#ifndef DATASTRUCTURE_D550413M
#define DATASTRUCTURE_D550413M

typedef struct tagDSD550413M
{
  char              szDOCNAME[9];      // string parm is passed into this header
} DSD550413M, *LPDSD550413M;  // and stored in this struct

#define IDERRszDOCNAME_2                          1L

#endif

......
// code from .c
#define B550413M_c
#include <B550413M.h>   // this is header above

{
   int nResult = 0;
   PFNJDE2CM lpJDE2CM;
   HINSTANCE hLibrary;

   hLibrary = LoadLibrary("c:\\JDE2CM.dll.dll"); // this is VB dll

   if(hLibrary != NULL)
   {
        // gets the address of the function inside the VB dll
        lpJDE2CM = (PFNJDE2CM) GetProcAddress (hLibrary, "DllGetClassObject");

            if(!lpJDE2CM)
      FreeLibrary(hLibrary);
            else
           {
               // call the VB dll function
                const char *docid = 0;          
      docid = lpDS->szDOCNAME;    
      nResult = lpJDE2CM(docid);    
           }
}

   return (ER_SUCCESS);
}
