我建立了一个不可见的主窗口，应用程序显示为托盘图标，
但无法响应右键菜单中的快捷键：我得主窗口重载了DefWindowProc，响应了托盘消息，但快捷键消息如何传递？
请各位大侠指条明路！
自当临贴涕淋，不胜感激！LRESULT CMain::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
// TODO: Add your specialized code here and/or call the base class
if (message == pnid.uCallbackMessage)
return OnSysTray(wParam, lParam);
return CWnd::DefWindowProc(message, wParam, lParam);
}

The WM_KEYDOWN message is posted to the window with the keyboard focus when a nonsystem key is pressed. A nonsystem key is a key that is pressed when the ALT key is not pressed. A window receives this message through its WindowProc function. LRESULT CALLBACK WindowProc(
HWND hwnd, // handle to window
UINT uMsg, // WM_KEYDOWN
WPARAM wParam, // virtual-key code
LPARAM lParam // key data
);
Parameters
wParam
Specifies the virtual-key code of the nonsystem key.
lParam
Specifies the repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown in the following table. Value Description
0–15 Specifies the repeat count for the current message. The value is the number of times the keystroke is autorepeated as a result of the user holding down the key. If the keystroke is held long enough, multiple messages are sent. However, the repeat count is not cumulative.
16–23 Specifies the scan code. The value depends on the original equipment manufacturer (OEM).
24 Specifies whether the key is an extended key, such as the right-hand ALT and CTRL keys that appear on an enhanced 101- or 102-key keyboard. The value is 1 if it is an extended key; otherwise, it is 0.
25–28 Reserved; do not use.
29 Specifies the context code. The value is always 0 for a WM_KEYDOWN message.
30 Specifies the previous key state. The value is 1 if the key is down before the message is sent, or it is zero if the key is up.
31 Specifies the transition state. The value is always zero for a WM_KEYDOWN message.
Return Values
An application should return zero if it processes this message. Res
If the F10 key is pressed, the DefWindowProc function sets an internal flag. When DefWindowProc receives the WM_KEYUP message, the function checks whether the internal flag is set and, if so, sends a WM_SYSCOMMAND message to the top-level window. The wParam parameter of the message is set to SC_KEYMENU. Because of the autorepeat feature, more than one WM_KEYDOWN message may be posted before a WM_KEYUP message is posted. The previous key state (bit 30) can be used to determine whether the WM_KEYDOWN message indicates the first down transition or a repeated down transition. For enhanced 101- and 102-key keyboards, extended keys are the right ALT and CTRL keys on the main section of the keyboard; the INS, DEL, HOME, END, PAGE UP, PAGE DOWN, and arrow keys in the clusters to the left of the numeric keypad; and the divide (/) and ENTER keys in the numeric keypad. Other keyboards may support the extended-key bit in the lParam parameter. Windows 2000: Applications must pass wParam to TranslateMessage without altering it at all.Requirements
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Header: Declared in Winuser.h; include Windows.h.
The WM_SYSKEYDOWN message is posted to the window with the keyboard focus when the user presses the F10 key (which activates the menu bar) or holds down the ALT key and then presses another key. It also occurs when no window currently has the keyboard focus; in this case, the WM_SYSKEYDOWN message is sent to the active window. The window that receives the message can distinguish between these two contexts by checking the context code in the lParam parameter. A window receives this message through its WindowProc function. LRESULT CALLBACK WindowProc(
HWND hwnd, // handle to window
UINT uMsg, // WM_SYSKEYDOWN
WPARAM wParam, // virtual-key code
LPARAM lParam // key data
);
Parameters
wParam
Specifies the virtual-key code of the key being pressed.
lParam
Specifies the repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown in the following table. Value Description
0–15 Specifies the repeat count for the current message. The value is the number of times the keystroke is autorepeated as a result of the user holding down the key. If the keystroke is held long enough, multiple messages are sent. However, the repeat count is not cumulative.
16–23 Specifies the scan code. The value depends on the original equipment manufacturer (OEM).
24 Specifies whether the key is an extended key, such as the right-hand ALT and CTRL keys that appear on an enhanced 101- or 102-key keyboard. The value is 1 if it is an extended key; otherwise, it is 0.
25–28 Reserved; do not use.
29 Specifies the context code. The value is 1 if the ALT key is down while the key is pressed; it is 0 if the WM_SYSKEYDOWN message is posted to the active window because no window has the keyboard focus.
30 Specifies the previous key state. The value is 1 if the key is down before the message is sent, or it is 0 if the key is up.
31 Specifies the transition state. The value is always 0 for a WM_SYSKEYDOWN message.
Return Values
An application should return zero if it processes this message. Res
The DefWindowProc function examines the specified key and generates a WM_SYSCOMMAND message if the key is either TAB or ENTER. When the context code is zero, the message can be passed to the TranslateAccelerator function, which will handle it as though it were a normal key message instead of a character-key message. This allows accelerator keys to be used with the active window even if the active window does not have the keyboard focus. Because of automatic repeat, more than one WM_SYSKEYDOWN message may occur before a WM_SYSKEYUP message is sent. The previous key state (bit 30) can be used to determine whether the WM_SYSKEYDOWN message indicates the first down transition or a repeated down transition. For enhanced 101- and 102-key keyboards, enhanced keys are the right ALT and CTRL keys on the main section of the keyboard; the INS, DEL, HOME, END, PAGE UP, PAGE DOWN, and arrow keys in the clusters to the left of the numeric keypad; and the divide (/) and ENTER keys in the numeric keypad. Other keyboards may support the extended-key bit in the lParam parameter.This message is also sent whenever the user presses the F10 key without the ALT key. Requirements
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.

}
}你要的话，可以把这个例子发给你。
zhdleo(叮东) 的程序和我差不多，只不过我得菜单用的是API做的。
在托盘响应右键，弹出菜单时，必须要激活当前的窗口，
我的主窗口时隐藏的，可以用SetForegroundWindow()函数；
不知道有什么通用的方法；if(uMouseMsg==WM_RBUTTONDOWN) //鼠标右键弹出菜单。
{
AfxGetMainWnd()->SetForegroundWindow(); //弹出Popup菜单
///////////增加
SetForegroundWindow()//////////////
CMenu menu;
menu.LoadMenu(IDR_TRAYMENU);
CMenu* pPopup=menu.GetSubMenu(0);
CPoint Point;
GetCursorPos(&Point);
pPopup->TrackPopupMenu(TPM_LEFTALIGN,Point.x,Point.y,AfxGetMainWnd(),NULL );
AfxGetMainWnd()->PostMessage(WM_NULL, 0, 0);
}另外AfxGetMainWnd()->PostMessage(WM_NULL, 0, 0);
发送空消息不知道有什么用，我在测试中删掉，也没出什么错。讨论一下再给分。。
不知道有什么通用的方法；"?
这个问题原来有帖子：
好象是ShowWindow(SW_HIDE);我的办法是移动程序界面出可视区域。
