在Main中GetMessage,或用MFC直接注冊(cè)這個(gè)消息(手動(dòng)加):
h文件中聲明消息處理涵數(shù):
afx_msg LRESULT OnProcess(WPARAM wParam, LPARAM lParam);
在cpp文件的消息映射中加上:
ON_MESSAGE(WM_DBNOTIFICATION,OnProcess)
關(guān)加上實(shí)現(xiàn)代碼:前提是EDB數(shù)據(jù)庫(kù)必須打開(kāi),可監(jiān)聽(tīng)聯(lián)系人,來(lái)電數(shù)據(jù)庫(kù)的變化.
LRESULT CMainFrame::OnProcess(WPARAM wParam, LPARAM lParam)
{

pNotification = (CENOTIFICATION*)lParam;

相對(duì)于CEDB,則是CEDB_EXNOTIFICATION.這個(gè)消息不適用短信數(shù)據(jù)庫(kù)(cemail.vol),
