The VC view class program can receive onkeydown messages, but on the dialog it needs to PreTranslateMessage handle the key messages.And the System Key ALT,F10 also need special treatment.or directly on the code:BOOL Ctestdlg::P retranslatemessage (msg* pMsg){Todo:add your specialized code here and/or call the base classCString str;CString STRMSG;int valid_down=0;static int shift=0;int capital=0;static int ctrl=0;static int alt=0;static int f10=0;Short

Create a dialog box-based project in VC and compile and run the project successfully. I am so happy with the project I just created. Suddenly a whim, pressed a return key, the project flash and gone. Compile and run again. Press the ESC key, and the project will flash away.Why is this true? The CDialog has the default "ENTER" and "ESC" keys.To solve this problem, press ENTER and ESC to close the project. The correct solution is to trigger the PreTranslateMessage message and intercept the message

the MFC message path, in this way, all message events of MFC can be located at will, and the processing process of MFC can be tracked and analyzed from any site. You can even start from the PumpMessage base camp and keep track of the entire process. The Startup Process of the dialog box is very simple. After the program enters the WinMain function, it will call the DoModal function of the dialog box and then enter the RunModalLoop function. The message loop starts here. Limited space, I will no

Afxgetthread ()-> pumpmessage () // pump message, but quit on wm_quit{Afxpostquitmessage (0 );Return-1;}...} While (: peekmessage (PMSG, null, pm_noremove ));}...} Here, afxgetthread ()-> pumpmessage () is the base camp of MFC message processing. All the messages in the MFC program start from here. After many path transformations, they go through the mountains and go straight to the Windows kernel, return to the MFC field, and find the final desti

Mediator (mediator) mode (mediator) defines an object that encapsulates how a series of objects interact so that objects do not need to be explicitly referenced to each other, which makes them more loosely coupled, and allows us to change the interaction of multiple objects independently. The structure diagram is as follows: With a chat room example, a chat room can be a lot of members, members can join different discussion groups, chat room is an intermediary, the members of the discussio

In VC6.0, you can do this by adding the splash component and then providing the function in the project invocation component. But there is no such component in the VS2008 (I have been looking for a long time, I did not find it, and there is no relevant information on the Internet). After reviewing the relevant information summarized as follows: 1, you need to add a special Class C Splashwnd. The code is as follows: SplashWnd.h #ifndef _splash_header _ #define_SPLASH_HEADER_ #pragmaonce #include

Afxpretranslatemessage ( (Pstate->m_msgcur))) {:: TranslateMessage ( (Pstate->m_msgcur));::D Ispatchmessage ( (Pstate->m_msgcur));} return TRUE;}This code is similar to the Win32 code we often write.Afxpretranslatemessage ( (Pstate->m_msgcur)BOOL afxinternalpretranslatemessage (msg* pMsg) {//assert_valid (this); CWinThread *pthread = Afxgetthread (); if (pThread) {//If th

Add a CToolTipCtrl type member to the class of the dialog box and initialize it as follows, where appropriate:M_tooltipctrl.create (this);M_tooltipctrl.addtool (GetDlgItem (Idc_button1), _t ("This is the ToolTip");M_tooltipctrl.setmaxtipwidth (123);M_tooltipctrl.activate (TRUE);2.
