Normally, edit controls in a dialog box use one common global data segment per dialog box. If the dialog box has style DS_LOCALEDIT, edit controls use the data segment pointed to by the hInstance used to create the dialog box. Edit controls created with CreateWindow() use the data segment pointed to by hInstance.

The GLBEDIT sample shows how to change hInstance to point to a new global object. Multiple controls of any type can use the same memory object.

To find the effected portions of the code, search for WM_CREATE in the MainWndProc.
