Very Computer

Hello everybody,

I am using eVC to develop an application for PocketPC.I am using SQLServer
CE as my device database.I am loading a bitmap onto my device.I want to save
the same to the database with 'image' datatype.

These are the declarations i am giving in the header file.

ULONG m_cRef;
void* m_pBuffer;
ULONG m_cBufSize;
ULONG m_iPos;

#define SAFE_RELEASE(pIUnknown) if(pIUnknown) (pIUnknown)->Release();
void operator void* const() { return m_pBuffer; };

STDMETHODIMP_(ULONG) AddRef(void);
STDMETHODIMP_(ULONG) Release(void);
STDMETHODIMP QueryInterface(REFIID riid, LPVOID *ppv);
STDMETHODIMP Read(void __RPC_FAR *pv, ULONG cb, ULONG __RPC_FAR *pcbRead);
STDMETHODIMP Write(const void __RPC_FAR *pv,ULONG cb,ULONG __RPC_FAR
*pcbWritten);

typedef struct tagDBOBJECT {  DWORD dwFlags;
                                                     IID iid;
                                               } DBOBJECT;

when i compiled i am getting the following error.

error C2549: user-defined conversion cannot specify a return type
error C2801: 'operator user-defined conversion' must be a <Unknown> member
error C2549: user-defined conversion cannot specify a return type
error C2801: 'operator user-defined conversion' must be a <Unknown> member

Do i need to include any  more header files to do this?

These are the header files i am including in my cpp file.

#define UNICODE
#define DBINITCONSTANTS
#define INITGID

#include <windows.h>
#include <stdio.h>
#include <stddef.h>
#include <iostream.h>
#include <oledberr.h>
#include <oledb.h>

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

This is the code in the saveBmp() function for saving the bitmap

IAccessor* pIAccessor = NULL;
ICommandText* pICommandText = NULL;
ICommandProperties* pICommandProperties = NULL;
IRowsetChange* pIRowsetChange = NULL;
IRowset* pIRowset = NULL;
DBBINDING rgBindings[cBindings];

struct BLOBDATA
{
DBSTATUS dwStatus;
DWORD dwLength;
ISequentialStream* pISeqStream;

Quote:};

These are the errors

 error C2065: 'DBBINDING' : undeclared identifier
 error C2146: syntax error : missing ';' before identifier 'rgBindings'
 error C2065: 'rgBindings' : undeclared identifier

 error C2065: 'pIRowsetChange' : undeclared identifier
 error C2065: 'IRowset' : undeclared identifier
 error C2106: '=' : left operand must be l-value

What might be the problem?Can anybody help me in this reagrd.

Thanking you,
