    Question child windows of group boxes and static controls

    i'm creating a program using a tab control. each tab loads a different static control that contains it's own buttons, text boxes, etc. how do i get the events from a button that is a child of a static box or a group box? i'm not using a dialog box, i'm using a regular window.
    any help would be appreciated.

    You are looking to tell the control where to send its msg's. This is the wndproc function

    If you created the controls on the fly then you will specify the parents HWND, msg's will be sent to its callback.

    If you registered a WNDCLASS then you will specify the wndproc as a member ie

    WinClassMyApp.lpfnWndProc=(WNDPROC)MyAppsCallback;

    Else each will have its own msg handler loop and callback.

    Question

    do you have any examples of this? i have petzold book, but it doesn't give an explanation of how to use a callback function for a child window such as a groupbox.
    also, i have another question. i created radio buttons and text boxes as children of my groupbox controls... will the events of these radio buttons and text boxes be sent to their parent (the groupbox) or can a group box do that sort of thing. i pretty much just need to know if it's possible to do it the way i am and if i should be going about it another way. another way that i thought of would be to just create the child window controls as children of my main window and just position them over the tab control and have them all created and destroyed on the fly. right now, i have them as children of a static control and am only creating and destroying the static controls on the fly.

    If I understand you have a main dlg / window with a TAB ctrl on it.
    You want to change to different sets of ctls as the user changes TAB's.

    Is each set of ctrls the same each time? So if the user clicks the 1st TAB will they always see the same ctrls?

    If so create them as seperate dialogs in the resource editor. Create them on init of the main window with CreateDialog(). You can specify where the msg's are sent with the DLGPROC param.

    the msg loop is
    Code:
    if (FALSE == IsDialogMessage(hDlg, &msg))
    {
            TranslateMessage(&msg) ;
    	DispatchMessage(&msg) ;
    }
    Use ShowWindow() to hide the ones not needed and SetWindowPos() to 'paste' the active dlg over the top of the TAB ctrl. (Find its client rect on the main window / dlg)
    If the TAB ctrl moves then use SetWindowPos() again.
    If the user changes TAB's hide the active dlg and show the new one. ShowWindow()
