突然想到又添加一个把“疯狂刷新”的托盘图标都隐藏的功能。于是百度了半天才弄到一个还可以的实现功能。


(添加uses CommCtrl;)

procedure HideAllTrace;
var TBHWND: HWND;
    i, count: Integer;
    PID, PRC: THandle;
    Buff: PChar;
    Info: _TBBUTTON;
    R: Cardinal;
    S: array[0..1024] of char;
begin
    TBHWND := GetSysTrayWnd;
    if TBHWND = 0 then exit;

    GetWindowThreadProcessId(TBHWND, @PID);
    PRC := OpenProcess(PROCESS_VM_OPERATION or PROCESS_VM_READ or PROCESS_VM_WRITE, False, PID);
    Buff := VirtualAllocEx(PRC, nil, 4096, MEM_RESERVE or MEM_COMMIT, PAGE_READWRITE);
    count := SendMessage(TBHWND, TB_BUTTONCOUNT, 0, 0); //托盘中button的个数,不一定是图标的个数,有些button是隐藏的。
    for i := 0 to count - 1 do
    begin
        FillChar(Info, SizeOf(Info), 0);
        WriteProcessMemory(PRC, Buff, @Info, SizeOf(Info), R); //消息使用的内存空间必须在Shell之内,所以利用ReadProcessMemoery和WriteProcessMemory。
        SendMessage(TBHWND, TB_GETBUTTON, i, Integer(Buff));
        ReadProcessMemory(PRC, Buff, @Info, SizeOf(Info), R);

        SendMessage(TBHWND, TB_GETBUTTONTEXT, Info.idCommand, Integer(Integer(@Buff[0]) + SizeOf(Info)));
        ReadProcessMemory(PRC, Pointer(Integer(@Buff[0]) + SizeOf(Info)), @S[0], SizeOf(S), R);
        if pos('疯狂刷新', StrPas(S)) > 0 then //如果button的TEXT中包含'疯狂刷新'
            SendMessage(TBHWND, TB_DELETEBUTTON, i, 0); //删除
    end;
    VirtualFreeEx(PRC, Buff, 0, MEM_RELEASE);
    CloseHandle(PRC);
end;

但终因这个功能太猥亵,有点你木马或恶意软件而没有添加到辅助工具里。
