c++ MFC和处理windows消息

Question

Windows消息的消息映射中需要什么代码?

调用函数的代码:

SendMessage(GRID_WM_UPDATECELL,(WPARAM)1,(LPARAM)&sDisp);

函数:

LRESULT CNJAGridCtrl::OnUpdateCell(WPARAM wParam, LPARAM lParam)
{
}

Answer 1

消息映射行应为

ON_MESSAGE(GRID_WM_UPDATECELL, OnUpdateCell) 

，函数签名应该是

LRESULT CNJAGridCtrl::OnUpdateCell(WPARAM wParam, LPARAM lParam);
