I have a custom control that defines several notification messages but these are not displayed in the Class Wizard in Visual Studio 2022. See the empty listbox "Messages" in this screen capture of Class Wizard:
How does the Class Wizard know which messages are available for a certain control in a dialog or CFormView??
I want to handle messages..

If you select other standard controls on that form view, does Class Wizard show anything for them?
I'm surprised you're not at least seeing COMMAND and UPDATE_COMMAND_UI messages showing.
If you select other standard controls on that form view, Class Wizard DOES show messages for them!
So how does Class Wizard know which messages are available for a certain control??
should I delete the .vs subdirectory to clean up Class Wizard?
is something important contained in .vs folder???
I derived a class from CFormView and added some controls to the form. This what the form looks like in the resource editor -
This is what Class Wizard shows for the form --
The usual control messages also appear for the other controls added to the form
Also, does deleting .vs folder help??
I suspect Class Wizard only "knows" about the common Windows controls, so that may be why you're not seeing anything for a custom control - though that's only my guessing. I don't recall ever reading of any mechanism to have it handle custom controls. You may just have to resort to adding the handlers manually.
I agree - but my problem is for a custom control: how do I define notification messages so Class Wizard recognizes them?
