() First sorts the messages by byte, calls the OnCommand () message response function for the WM_COMMAND message, and calls the OnNotify () message response function for the WM_NOTIFY message. Any missed messages will be standard messages. The onwndmsg () function searches the message image of the class to find a handler function that can handle any window message. If the onwndmsg () function cannot find such a handler function, it returns the messag
for the Cplaytoolbar class to handle the 3 button command events itself, it is necessary to transfer the route from the Cplaydialog class to its child window toolbar so that the Cplaytoolbar class gets the chance to handle it. The action is to overload the OnCommand virtual functions of Cplaytoolbar and Cplaydialog, and the cplaydialog code is as follows:1BOOL Cplaydialog::oncommand (WPARAM WPARAM, LPARAM

Wince Edit Control copy/paste
Author: Lai yuping (aulyp@163.com)
In Windows CE, when you write an MFC program, the Edit Control is frequently used. However, by default, the content you input on the control does not support copying and pasting, there is no right-click menu, which is very inconvenient. I found no detailed information on Google. I can only read the help documentation of E. In fact, it is not difficult to implement it. The following is the step, share it with you.

, in this way, the system sends you the set function when the Set message is available. Here is the _ afxcbtfilterhook function), so that each time you create a window, this function modifies the window function to afxwndproc. Why? It is compatible with mfc2.5 to accommodate new 3D controls.
V,MFC message flowThe starting point of a message is the afxwndproc function. All messages are sent to afxwndproc, and they are routed from afxwndproc to their respective message response functions again. Ho
Midp2.0 introduces three layout policies:Choice. text_wrap_on: the part that exceeds the limit is displayed in the next row.Choice. text_wrap_off: the part that exceeds the limit is ignored.Choice. text_wrap_default: Default policy, same as choice. text_wrap_on
The setfitpolicy and getfitpolicy methods can be used to set and obtain the current layout policy.

The order in which messages are processed in the MFC Application1. afxwndproc () This function is used to receive messages, locate the cwnd object to which the message belongs, and then call afxcallwndproc.

Same as MFC.
First, define a MSGMAP_ENTRY structure and a dim collection:
Struct MSGMAP_ENTRY {
UINT nMessage;
LONG (* pfn) (HWND, UINT, WPARAM, LPARAM );
};
# Define dim (x) (sizeof (x)/sizeof (x [0])
Note that the second element of MSGMAP_ENTRY, pfn, is a function pointer.

Next, organize the two arrays _ messageEntries [] and _ commandEntries [] to remove
