After that you have a member variable which contains the text of the edit control. Use the class wizard to add a member variable from type 'value' to your edit control. If the flag has been set, the system stops the message loop, clears the dialog box, and uses the value in nResUlt as the value returned from the function that created the dialog box.In addition there are three ways to get or set text from or to an edit control. The system checks the flag before trying to retrieve the next message from the application queue. Instead, it sets a flag and allows the dialog application to return control to the system. The EndDialog function does not immediately clear the dialog box. If the application calls this function during WM_INTDIALOG message processing, the dialog box is cleared before the display and input focus are set. The dialog box application can call the EndDialog function at any time even during WM_INITDIALOG message processing. This function cannot be used for other purposes. The application calls the EndDialog function from within the dialog application. Note: The dialog box created by the DialogBox, DialogBoxParam, DialogBoxlndirect and DialogBoxlndirectParam functions must be cleared by the EndDialog function. If you want to get error information, please call GetLastError function. Return value: If the function call succeeds, the return value is non-zero if the function call fails, the return value is zero. NResult: Specify the value returned to the application from the dialog box function creation. HDlg: indicates the dialog window to be cleared. Windows CE: This function will not send WM_NCDESTROY message.įunction function: This function clears a modal dialog box and makes the system suspend any processing of the dialog box.įunction prototype: BOOL EndDialog(HWND hDlg,int nResult) If this window is a child window without WS_EX_NOPARENTNOTIFY style, the WM_PARENTNOTIFY message will be sent to its parent window when the window is destroyed.
GETWINDOWTEXT MFC WINDOWS
Note: A thread cannot use this function to destroy windows created by other threads. If you want to get more error information, please call GetLastError function. Return value: If the function succeeds, the return value is non-zero: If the function fails, the return value is zero. HWnd: the handle of the window to be destroyed. This function also destroys the menu of the window, clears the message queue of the thread, destroys the timer related to the window procedure, releases the window's ownership of the clipboard, and interrupts the viewing chain of the clipboard.įunction prototype: BOOL DestroyWindow( HWND hWnd//handle to window to destroy) This function invalidates the window and removes its keyboard focus by sending WM_DESTROY and WM_NCDESTROY messages. The application must use the DestroyWindow function to destroy the window.įunction function: destroy the specified window. The system displays the icon of the window instead of the window, and displays the window title under the icon. Note: The window size is minimized to an icon and moved to the icon area of the screen. Return value: If the function succeeds, the return value is non-zero if the function fails, the return value is zero. HWnd: the handle of the window to be minimized. Note: CDialog::CloseWindow() just minimizes the dialogĭetailed explanation of related functions:įunction function: This function minimizes the specified window, but does not destroy the window.įunction prototype: BOOL CloseWindow(HWND hWnd)
