How to create controls that have a 3D border at run time by using MFC in Visual C++ (132243)

MORE INFORMATION

The new extended-window style WS_EX_CLIENTEDGE specifies that a window is to have a 3D border. All controls created by the dialog manager are created with that style automatically added. To create a control at run time that has a 3D border, you have to add that style yourself.

Because WS_EX_CLIENTEDGE is an extended style, you cannot use the Create() member function to create a control. You must call CreateEx(), and pass the appropriate Windows class name as well. For example, to create an edit control at run time, you could use this code:

   m_Edit.Create(WS_CHILD | WS_BORDER | WS_VISIBLE,
                 CRect(10,10,100,100),pParent,nID);
				

Here m_Edit is a CEdit object, pParent is a pointer to a parent window, and nID is an ID of an edit control. To add a 3D border, create control by using this code:

   m_Edit.CreateEx(WS_EX_CLIENTEDGE,"EDIT","",
                   WS_CHILD | WS_BORDER | WS_VISIBLE,
                   10,10,100,100,pParent->GetSafeHwnd(),(HMENU)nID);
				

Note While Visual C++ versions 2.2 and above define WS_EX_CLIENTEDGE in WINUSER.H, Visual C++ version 2.1 does not. Therefore, if you're using version 2.1, you must include the following definition in your code:

   #define WS_EX_CLIENTEDGE        0x00000200L
				

If you're using Visual C++ versions 2.2 and above, the WS_EX_CLIENTEDGE constant is automatically defined when you include AFXWIN.. Therefore, no additional work is necessary.

Keep in mind that the WS_EX_CLIENTEDGE style applies to any window, not just controls. In Visual C++ versions 2.2 and above, MFC automatically adds WS_EX_CLIENTEDGE for frames and views but not for CWnd-based windows or controls.

To create other standard controls, you have to specify their pre-defined Windows class name: BUTTON, COMBOBOX, LISTBOX, SCROLLBAR, or STATIC.
