For me, it was really hard to get a working code for Win32 API, since I don't code in MFC. The only help I was able to get wasWin32.hlpWhich contains every

Review Win32 API and win32api A friend said that the print window function should be added to a project developed by VC ++ 6.0 to help write code for its call. Of course, I don't want to touch this old IDE, and I don't like the clumsy and unclear encapsulation of MFC. So I decided to use a pure Win32 API and then simpl

Controls created with the CreateWindow function, if you want to switch with the TAP key, the simplest way is: the main window has ws_ex_controlparent extension properties, the control has ws_tapstop properties.Then the most important thing is to make a judgment when dealing with the message loop : 1 while(GetMessage (msg, NULL,0,0))2 {3 if(! IsDialogMessage (hwnd, AMP;MSG))//Not the HWND, not the message.4 {5TranslateMessage (msg);6DispatchMessage (msg);7 }8 9}

This blog mainly describes how to use Win32 API to compile a system tray. The following functions are implemented: Display prompt box, bubble, and context menu. Implementation System The main function used in the system tray is shell_policyicon, And the struct used is policyicondata. After running, we can see our tray in the taskbar. When we move the mouse over the tray icon, right-click the context menu, w

We continue to Win32 the topic of debugging APIs. In this chapter, we will learn how to modify the debugger. Theory: In the previous chapter, we learned how to load the process being debugged and how to handle events that occurred in the process. For practical purposes, our program should have the ability to modify the program being debugged. There are several API functions for this purpose. ReadProcessM

Qt sends messages to Win32 very easily, but it is very complicated to obtain Windows messages. Finally, I thought of a method that is not perfect, but it is also the only way that I can achieve it now, the basic principle is to use VC to compile an mfc dll, which creates a transparent form and uses this DLL to obtain Win32 API messages. The source code has been
