SendMessage() to a tabbed dialog
-
I created a tabbed dialog (with 2 tabs) without property sheets. I created a menu on the main dialog that I want to associate with one of the tabs of the tabbed dialog. I want to convert temperature on the embedded dialog to a celsius value when selecting the option from the menu. I have an error when using the SendMessage function. The commented statements are different ways I have attempted to send a message but they are incorrect. A pointer references each embedded dialog. Following this function are excerpts from my code (main dialog file, embedded dialog file). Does anyone have any suggestions? void CMotionAnalyzerDlg::OnTemperatureCelsius() { /* linking error ASSERT(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL));*/ //m_dPointer[0]->SendMessage(WM_MENU_CELSIUS,0,0); /* errorC2664: caanot convert parameter 1 from _3DSEmbeddedDialog* to UINT */ //SendMessage(m_dPointer[0], WM_MENU_CELSIUS); /* errorC2664: caanot convert parameter 1 from HWND to UINT */ //SendMessage(m_dPointer[0]->m_hWnd, WM_MENU_CELSIUS); } --------------------------------------------------------------------------------------- //MAIN DIALOG HEADER FILE class CMotionAnalyzerDlg : public CDialog { public: ...

This means that tabbed window you are talking about, is not considered as window, thats why

You need to modify this to,
::SendMessage(m_dPointer[0]->m_hWnd, WM_MENU_CELSIUS,0,0);
But, again it should be valid window.. p.s. Its better to divide problem in small sub problem. Nobody like to read such huge code, like me( posted without using
