编程隐藏其他程序的托盘图标

[DDGG]

有一个软件，运行时会在任务条右下角显示托盘图标，但是它自己又没有选项可以设置不显示。
有没有办法通过编程实现隐藏其他程序的托盘图标呢？

我目前想到的办法是用CreateProcess加载该软件，然后用CreateRemoteThread调用LoadLibrary函数为该进程装入一个DLL，在DLL里替换掉这个进程的Shell_NotifyIcon函数，让它什么也不干。

有人写过类似的代码么？可否给个例子，谢谢！

嗯，这个我比较擅长。

	HWND hWnd = FindWindow(_T("Shell_TrayWnd"), NULL);
	if (hWnd == NULL) return FALSE;
	hWnd = FindWindowEx(hWnd, NULL, _T("TrayNotifyWnd"), NULL);
	if (hWnd == NULL) return FALSE;
	::EnableWindow(hWnd, bShow);    // 托盘区禁用，防音量打开
	hWnd = FindWindowEx(hWnd, NULL, _T("SysPager"), NULL);
	if (hWnd == NULL) return FALSE;
	hWnd = FindWindowEx(hWnd, NULL, _T("ToolbarWindow32"), NULL);
	if (hWnd == NULL) return FALSE;

	DWORD dwProcessID;
	GetWindowThreadProcessId(hWnd, &dwProcessID);
	HANDLE hProcess = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_READ | PROCESS_VM_WRITE,
								  FALSE, dwProcessID);
	if (hProcess == NULL) return FALSE;

	int nItemCount = (int)SendMessage(hWnd, TB_BUTTONCOUNT, 0, 0);
	PVOID pvData = VirtualAllocEx(hProcess, NULL, sizeof(TBBUTTON),
								  MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
	if (pvData == NULL || nItemCount < 1)

		{
			SendMessage(hWnd, TB_HIDEBUTTON, bi.idCommand, !bShow);
		}
	}
	VirtualFreeEx(hProcess, pvData, 0, MEM_RELEASE);
	CloseHandle(hProcess);

	// 刷新托盘
	::SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);
	return TRUE;
}

需要自己修改一下。
这是我在一个工程里隐藏图标的，不过，我排除了音量、卡巴等图标。
自己看着修改一下，就可以调用了。

要隐藏指定程序的托盘图标，只需要修改下面代码：通过比较类名来区别。

 // 排除，if (bi.fsState & TBSTATE_HIDDEN)可判状态
        if (StrCmp(szClassName, _T("Connections Tray")) == 0 ||
                StrCmp(szClassName, _T("SystemTray_Main")) == 0 ||
                StrCmp(szClassName, _T("#32770")) == 0 ||
                StrCmp(szClassName, _T("AVP.Tray")) == 0)
        {
            continue;
        }
