How to use P\Invoke in VB.Net

I have number of C++ API's and I want to access them using P\Invoke in VB.Net.Following are the C wrapper written for some of the API's.Can anybody tell me how to use P\Invoke to access these methods in VB.Net.

In wrapper.h:

typedef void * VERIFY_HANDLE;
extern VERIFY_HANDLE Verify_Create();
extern void VERIFY_SetVerified(VERIFY_HANDLE, bool);
extern bool VERIFY_GetVerified(VERIFY_HANDLE);
/* etc, etc */

In wrapper.c:

#include "wrapper.h"
#include "Verify.h"
VERIFY_HANDLE Verify_Create() { return (VERIFY_HANDLE) new Verify(); }
void SetVerified(VERIFY_HANDLE h, bool b) { ((Verify *)h)->SetVerified(b); }
bool GetVerified(VERIFY_HANDLE h) { return ((Verify *)h)->GetVerified();  }
Solution

  • The free P/Invoke Interop Assistant can create Vb.Net P/Invoke code automatically from that C header file.
