  Hi Y'all,

  can someone help me convert the next few lines of code from c++ to c#?

  I've given it a try myself but my program keeps crashing when I use my c# code. I think the difficulty lies in converting the different datatypes. Help is greatly appreciated.

  Here's tha code:

  BOOL EXAPI
  SetCallback(
        WORD  wPortNumber,
     BOOL (CALLBACK* lpfnCallbackProc)(WORD, ULONG, INT, LPCALLBACKDATA, LPVOID),
     LPVOID   lpParam,
     BOOL  bDoCoInitialize = FALSE
     );
  
  
  
  
  
  

  BOOL CALLBACK EXPORT CallbackProc(WORD wPortAddress, ULONG ulIPAddress, INT cCommand, LPCALLBACKDATA lpData, LPVOID lpParam)
  {
    return TRUE;
  }
  
  
  

  // Definitions for callback functions
  typedef struct tagBLOCKELEMENT {
   DWORD dwStructSize;    // structure size
   LONG nType;      // data type (see constants below)
   LPVOID lpData;      // pointer to data
  } BLOCKELEMENT, *PBLOCKELEMENT, FAR *LPBLOCKELEMENT;
  
  
  
  
  

  typedef struct tagCALLBACKDATA {
   DWORD   dwStructSize;  // structure size
   LONG   nStartNo;   // start number of data block
   LONG   nNumberOfElements;  // number of data elements
   LONG   nBlockMode;   // mode of block operation
   LPBLOCKELEMENT lpDataBlock;  // pointer to data block
  } CALLBACKDATA, *PCALLBACKDATA, FAR *LPCALLBACKDATA;
  
  
  
  
  
  
  
  
  
  

  Thanks in advance everyone.
