Where can I put the MFC Control initialization code

Question

I am writing an MFC CEdit control and I need to add the initialization code after populating the m_hwnd control.

What function can I override or what message can I process for this?

I tried with OnCreate but it seems to work only for dialogs

EDIT: The thing I initialize is the cue edit banner

thanks

Answer 1

Following the prompt of Mark Ransom, I finally found a better function to implement my initialization. Although overloading CWnd :: SubclassWindow is a good idea, this function is not virtual and will require a call from a subclass pointer. Calling SubclassWindow from CWnd * will not work.

I found the function CWnd :: PreSubclassWindow . It is virtual and is called immediately before SubclassWindow. Since m_hwnd is really there, this is a good place to write the code I need. In addition, this function is virtual and is automatically called a wireframe, so I don’t have to worry about having a good pointer type

OnCreate does not work if the control is in the dialog box, because the control is created before it is subclassed into your window class - this happens in the DoDataExchange dialog box.

You can override CWnd :: SubclassWindow and call the base method before your own code.

Depending on what you initialize, you can override OnPaint() or add the initialization code to OnInitDialog() in the Dialog class that contains the control.
