Create a dialog-based WIN32 application (ii)--button app, New Subform

You can find the form created in the previous section, click OK and cancel two buttons without any reaction. Now let's add the ability to exit the dialog box for them.

6. First define the macro replacement as follows:

7. The function (Dlg_oncommand) that invokes the response message in the callback function (DLG_PROC) is as follows:

8, because Handle_wm_command is defined in the Windowsx.h header file, add its reference.

9. Next, define the message response function (Dlg_oncommand) that you just called, as follows:

Where Idok and Idcancel are the corresponding identifiers for button OK and cancel respectively.

10. Press F5 Start Debugging, then click OK or Cancel button to see the new dialog will be closed.

Here we show how to create a new subform.

11, first in Solution Explorer or Resources View right-click Add Resource, select dialog. and find the new dialog in the resources View, right-propertise modify the relevant content.

12. Click and press DELETE to delete the useless OK and Cancel buttons in the new sub-dialog box. Remember to delete or comment out the associated code for the deleted control when the Reasource.h or. cpp file exists.

13. Open Toolbox (ctrl+alt+x) in view, add the static test control to the new subform, modify the contents of the control, and adjust both to the appropriate size.

14. Find the button in the previous dialog and modify its propertise.

15. Switch to the. cpp file, modify the called message response function (Dlg_oncommand), call Dialogboxparam in the Idnew case, and write the callback function (NEWDLG_PROC) of the Child dialog box.

16. Press F5 Start Debugging, then click the New button to see the New sub-dialog box that you just created.
