DefBtn.exe Creates Default Border Around a Push Button


The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1


DefBtn.exe is a sample that demonstrates the correct message sequence to change the status of a push button from the "normal" state to the "default" state. The default push button receives a message when the ENTER key is choosen in a dialog box, no matter which control currently has the focus.

In the DefBtn.exe sample, when a numeral button is pressed ("1", "2", or "3") the corresponding number button ("one", "two", or "three") becomes the default button.

For a button to be correctly activated by using an accelerator, it is necessary to subclass the button to process the focus messages. This is caused by the fact that accelerators bypass some steps in the message flow.
