The dialog box cannot respond to keyboard messages.

This is a strange thing. After looking for reasons for a long time, the final discovery is crazy.

Phenomenon: the dialog box cannot be closed by pressing ESC or returning to the car (I have not processed the pretransplantemessage). I can use Spy ++ to view it. The dialog box cannot receive any Keyboard Message.

Cause: tab stop is set in the property of a control in the dialog box. ws_tabstop is added in the RC file.

Solution: remove the tab stop style! Alas, really! # $ %! $ %! $ % ^ @ # % &*! % $!

 

It seems that each rowCodeYou have to think about it before adding it, just like processing the message of MFC. In the end, if you want to return true or false, you may encounter problems if you do not want to know it clearly.
