If you need to apply the currently selected Visual Manager to an existing dialog box (form view or property page), you must make the following changes in the source code:

1. Change the parent (base) class name: you must make the following replacements in .h and .cpp files:

CDialog-CBCGPDialog.

CPropertySheet-CBCGPPropertySheet.

CPropertyPage-CBCGPPropertyPage.

CFormView-CBCGPFormView.

two。 Call EnableVisualManager in the constructor of the dialog class (as far as the property sheet is concerned, calling this method only in the class constructor derived from CBCGPPropertySheet is sufficient: all pages are automatically themed).

3. If some controls on the dialog box are already associated with control member variables, such as CButton or CEdit, you must replace the class name of MFC with the appropriate library name. If the control does not have member variables, it automatically sets the theme.

4. If the dialog box contains list boxes or combo box controls, you must change their style to owner-draw + "Has strings" and add CBCGPListBox / CBCGPComboBox variables to those controls (due to Windows limitations, the mentioned style cannot be changed after the list / combo box has been created), so we cannot make this change.

For example, if you perform all the above steps on the following MFC dialog box:

The result will be:
