[解决办法]
#define LOAD_BITMAP(hbmp, bid) \
(hbmp) = LoadBitmap(hInst, MAKEINTRESOURCE(bid));

#define SET_BITMAP(hbmp, cid) \
SendMessage(cid, BM_SETIMAGE, (WPARAM) IMAGE_BITMAP, \
(LPARAM) (HANDLE) hbmp);


使用方法:
HINSTANCE hInst = _Module.GetResourceInstance();
LOAD_BITMAP(m_hClearBmp, IDB_CLEAR);

SET_BITMAP(m_hClearBmp, m_btnClearCust.m_hWnd);
