Hello Experts...
Did any one hear about Mapinfo?.

Well.... The provide the following file: "mapinfow.h"

It looks something like this...

class DMapInfo : public COleDispatchDriver
{
// Attributes
public:

// Operations
public:
     // method 'QueryInterface' not emitted because of invalid return type
     // method 'AddRef' not emitted because of invalid return type
     // method 'Release' not emitted because of invalid return type
     LPDISPATCH GetApplication();
     LPDISPATCH GetParent();
     CString GetName();
     CString GetFullName();
     CString GetVersion();
     BOOL GetVisible();
     void SetVisible(BOOL bNewValue);
     long GetLastErrorCode();
     void SetLastErrorCode(long nNewValue);
     CString GetLastErrorMessage();
     LPDISPATCH GetMBApplications();
     void Do(LPCTSTR command);
     CString Eval(LPCTSTR expression);
     void RunCommand(LPCTSTR command);
     void RunMenuCommand(short id);
     LPUNKNOWN DataObject(long windowID);
     void SetCallback(LPDISPATCH callbackobject);
};

There are some other classes defined...
The problem is that they are classes derived from MFC....
And I am not using (And I refuse to :-) MFC.

Can any one tell me how to create an object like this but not using MFC?....

Thankks

You can use the #import directive to import the type library, doesn't require MFC, and the generated wrapper classes are much better IMO. However, you need to be proficient with exception handling.

#import "typelibrary.tlb/dll/whatever" rename_namespace("nsMyTypeLib")

try {
  nsMyTypeLib::IMapInfoPtr pMI; // Interface name + "Ptr"
  pMI.CreateInstance(__uuidof(MapInfo/* Co Class Name */));
  pMI->Method();
}
catch (_com_error ce) {
  ce.ReportError(); // or whatever to handle the error
}
