How to Initialize contents of a dialog?


In MFC, the contents of a dialog are initialized if they are
associated with their corresponding data members. This is
done through "UpdateData(FALSE)" function. The control data
is transferred to the data members through "UpdateData(TRUE)".

In WIN32, the dialog data in controls can be initialized
during WM_INITDIALOG call. The control data can be updated
to the dialog members using apppropriate "SendMessage"
