GetActiveWindow

iayd

Hi, There are many dialog boxes in my project. I want to know that which one is active at a certain time. For example;

    CDlg1 \* dlg1;   // A global object for the dialog box.
dlg1= new CDlg1;
dlg1->Create(IDD\_DIALOG1,this);

CWnd * wnd;
wnd = (CDialog*)GetActiveWindow();
if(wnd == dlg1)
wnd->DestroyWindow();

I wrote this code to close the window. How can I know that which wnidow is active? Thanks

You can use GetFocus() Or GetForeGroundWindow() functions.

Since you're creating your child dialogs by passing your main dialog as parent, call GetTopWindow() by passing parent window handle. It will give you the top most window of your application. Regards, Jijo.

These are not working in my situations.I think the problem is not about GetActiveWindow(). The problem is that when I want to know if this window (active window) is the same window with the dialog box that I created before, it couldn't compare them. This part has problem I think;

if(dlg == wnd)

Thanks. That solved the problem.

Use window handles instead of MFC objects to compare. Since MFC window objects are just wrappers around window handles. if( wnd.GetSafeHwnd() == dlg1.GetSafeHwnd() ) ;;//...
