为何向主线程发送一条消息，主线程却没有响应。

Question

我在CMainFrame中
ON_COMMAND_RANGE(0,0xFFFF, OnCommandRange)捕获所有的WM_COMMAND消息，
结果诸如ID_APP_ABOUT,ID_FILE_NEW等命令消息都被捕捉了，主线程CWinApp没有处理。
我在自己的OnCommandRange（)函数最后加入
const MSG *pMsg=GetCurrentMessage();
afxGetApp()->PostThreadMessage(pMsg->message,pMsg->wParam,pMsg->lParam);
将帮助消息传给主线程，但依然没有效果。为何啊？

Answer 1

呵呵，是有点怪，帮不上了，只好帮你up,gz一下了

Answer 2

主线程应该用ON_THREAD_MESSAGE声明把

Answer 3

主线程是这样的：
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
//{{AFX_MSG_MAP(CMainFrame)
ON_WM_CREATE()
ON_MESSAGE(WM_OUTBAR_NOTIFY,OnListGroupNotify)
//}}AFX_MSG_MAP
ON_UPDATE_COMMAND_UI_RANGE(0,0xFFFF,OnUpdateCommandUIRange)
ON_COMMAND_RANGE(0,0xFFFF, OnCommandRange)
END_MESSAGE_MAP()

Answer 4

sorry 发错了：是这样的才对：
BEGIN_MESSAGE_MAP(CBiomApp, CWinApp)
//{{AFX_MSG_MAP(CBiomApp)
ON_COMMAND(ID_APP_ABOUT, OnAppAbout)
// NOTE - the ClassWizard will add and remove mapping macros here.
//    DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
// Standard file based document commands
ON_COMMAND(ID_FILE_NEW, CWinApp::OnFileNew)
ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)
// Standard print setup command
ON_COMMAND(ID_FILE_PRINT_SETUP, CWinApp::OnFilePrintSetup)
END_MESSAGE_MAP()

Answer 5

我在自己的OnCommandRange（)函数最后加入
const MSG *pMsg=GetCurrentMessage();
afxGetApp()->PostThreadMessage(pMsg->message,pMsg->wParam,pMsg->lParam);

Answer 7

你在app中用ON_THREAD_MESSAGE宏试试。

Answer 8

老兄，你是向主线程PostThreadMessage
主线程应该用ON_THREAD_MESSAGE声明这个消息才行啊

Answer 9

奇怪，不应该这样。
既然是截获所有Command消息，直接重载CMainFrame::OnCommand()吧：
WORD wNotifyCode = HIWORD(wParam); // notification code 
WORD wID = LOWORD(wParam);         // item, control, or accelerator identifier 
HWND hwndCtl = (HWND) lParam;      // handle of control 
注意把不处理的Command消息留给基类处理。

Answer 10

在MDI中不行在SDI和Dialog中是可以的!

Answer 11

你再试试app类的PreTranslateMessage，看能不能收到你发出的消息。

Answer 12

try this:
_AFX_THREAD_STATE* pThreadState=AfxGetThreadState();
MSG& msg = pThreadState->m_lastSentMsg;
PostThreadMessage(msg, msg.wParam, msg.lParam);
