Answer 1

Using Spy++Spy++ (SPYXX.EXE) is a Win32-based utility that gives you a graphical view of the system抯 processes, threads, windows, and window messages. With Spy++, you can: ?Display a graphical tree of relationships among system objects, including processes, threads, and windows.
?Search for specified windows, threads, processes, or messages.
?View the properties of selected windows, threads, processes, or messages.
?Select a window, thread, process, or message directly from the view.
?Use the Finder Tool to select a window by mouse positioning.?Set message options using complex message log selection parameters.Tip   While using Spy++, in many instances you can click the right mouse button to display a pop-up menu of frequently used commands. The commands available depend on where the pointer is. For example, if you click while pointing at an entry in the window view and the selected window is visible, the pop-up Highlight menu item will cause the border of the selected window to flash so that the window can be easily located on the screen.看到怎么用了 谢谢刺客

}晕倒用SPY++看不到WM_KEYDOWN  消息只有WM_KEYUP+一个虚拟键值

Answer 4

顶，你可以在重载proc中，对三个消息，都用outputdebugstr，来看看那个有信息输出，这样就可以看出那个消息相应了

Answer 5

我加了几行程序         case WM_KEYDOWN:
 MessageBox(hwnd,"keydown","weixin",0);
break;
case WM_KEYUP:
MessageBox(hwnd,"keyup","weixin",0);
break; case WM_CHAR:
char szChar[20];
sprintf(szChar,"char is %d",wParam);
//MessageBox(hwnd,szChar,"weixin",0);
break;证明  三个消息都有！！
SPY++还是不会用吧仔细读说明去
