How to use the VC 5.0 implementation toolbar and its properties to control the VC 5.0-style toolbar with a flat appearance, with a "handle" on the left, you can drag this "handle" to move the toolbar with the mouse. The toolbar has a divider (as shown in Figure 1). When the mouse moves on the toolbar, the corresponding button on the toolbar highlights. The enhanced toolbar Cenhancetoolbar, which is discussed herein is derived from the CToolbar class, and is a supplement and extension of the CToolbar class. If you don't care if there is any "handle" in the toolbar, it is very simple to generate a flat toolbar. You only need to add a sentence in the cmainframe's oncreate () function (you must add a function of the toolbar, because the MFC is generated when generating the toolbar): //mainfrm.cpp int CMAINFRAME: ONCREATE (... {... if (! M_wndtoolbar.create (this) // !m_wndtoolbar.loadtoolbar(idr_mainframe) {trace0 ("failed to create toolbar / n"); return -1; // fail To create} m_wndtoolbar.modifystyle (0, tbstyle_flat); // Setting toolbar is flat format ...} If your computer is installed 4.71.1712.3 version of ComctL32.dll (this dynamic library is issued with IE 4.0 ), It is better, your toolbar will automatically draw the separation line. You can move this toolbar through the non-button area of the mouse drag toolbar. The toolbar in GetRight is like this. If you have to get better (more "professional") toolbar, then please do it step by step. 1. Add a new class, this article is called the Cenhancetoolbar class, derived from the CToolbar class. 2. Add a member variable and function to the CENHANCETOOLBAR class and set its access attributes according to your needs.

Similarly, this operation is also required when the button status changes (press or release).
