If you want to do stuff like that, subclass the picturebox and handle WM_PAINT. Don't write picture box painting code inside dialog WM_PAINT handler.

Add WM_PAINT and this function OnPaint
You can use handle dc(CPaint dc(this)
dc.line..
dc.textout

Hi Engineer Masood,
I m not sure because i dont test this suggestion but
I think you can derived from one class that you need and then insert wm_paint in the derived class

Hi!
I have made menu item dynamically, by CWnd::InsertMenu
I don't know how to add command handlers to new items, which
I create dynamically.
Can you help me?
Thanks.

Just add WM_COMMAND handlers using the id of the menu you created. Keep track of the ids.

The problem is that I don't know the ID of my command at compile-time.
I'm reading menu data from database and building menu dynamically at run-time.
So event handlers must be set at run-time also.

|
|
You can override OnCommand and handle the menu events. For more info look up OnCommand in MSDN.

you can use ON_COMMAND_RANGE(id, idLast, memberFxn) to handle a rande of id's.

Hi!
I have the following problem:
I'm making dynamic menu this way:
CMenu* MainMenu = m_pMainWnd->GetMenu();
MainMenu->InsertMenu(-1, MF_BYPOSITION, 1, TEXT("&My menu"));
But after the program does this, the menu appears only after I
change something in my window, for example move mouse over menu.
The command: m_pMainWnd->UpdateWindow(); doesn't help.
So, what should I do?
Thanks for any help!
