How to SetFocus to a CButton so that the border and focus dotted line are visible?

Answer 1

By calling UpdateWindow, the button is being redrawn before the focus change can take effect. The Invalidate should be sufficient by itself, the window will get repainted when everything settles down.

Answer 2

This draws the thick border around the button:

static_cast<CButton*>(GetDlgItem(IDC_BUTTON1))->SetButtonStyle(BS_DEFPUSHBUTTON);

A more elegant way to do this would be to define a CButton member variable in CbuttonfocusDlg and associate it to the IDC_BUTTON1 control, and then calling

this->m_myButton.SetButtonStyle(BS_DEFPUSHBUTTON);

This makes the button to which I'm setting the focus the default button, but note that when the focus goes to a control (inside the dialog) that is not a button, the default button is once more the original default button set in the dialog resource, in this case the "Ok" button.

Answer 3

Use WM_NEXTDLGCTL.
