如何把键盘上的windows键屏蔽掉（windowsxp下，98下）

Question

不小心碰到就出开始菜单，不利于输入。

Answer 1

试试 ：function LowLevelKeyboardProc(nCode:integer;WParam:WPARAM;LParam:LPARAM):LRESULT;stdcall;
type
KBDLLHOOKSTRUCT=record
    vkCode:DWORD;
    scanCode:DWORD;
    flags:DWORD;
    time:DWord;
    dwExtraInfo:dword;
end;
var
   fFlag:BOOL;
   p:^KBDLLHOOKSTRUCT;
begin
   result:=0;
   fFlag := false;
   p:=Pointer(LPARAM);
   if (ncode=HC_ACTION) then
   begin
   case wparam of
    WM_KEYDOWN,
    WM_SYSKEYDOWN,
    WM_KEYUP,
    WM_SYSKEYUP:
    fFlag :=(p.vkCode = VK_Lwin) or (p.vkCode = VK_Rwin)or (p.vkCode = VK_apps);
    end;
    end;
    if fFlag = true then
       Result:=1;
    if ncode <> 0 then
       Result := CallNextHookEX(0,ncode,wparam,lparam);
end;
调用：procedure TForm1.Button1Click(Sender: TObject);
const
    WH_KEYBOARD_LL=13;
begin
  setwindowshookexw(WH_KEYBOARD_LL,LowlevelKeyboardproc,hinstance,0);
end;

设置敏感健：resgisterHotKey(handle,GlobalAddAtom(Pchar(UserDefineHotKey))-$C000,
               MOD_win ,//要不就是MOD_Windows,记不清了
               nil);消息响应函数：procedure WMhotKeyhandel(var msg:Tmessage);message Wm_HotKey;begin  if msg.lpararmLo=Mod_win then
   .....end;释放敏感健：
 unregisterhotkey(handle,GlobalAddAtom(Pchar(UserDefineHotKey))-$C000);
 deleteAtom(GlobalAddAtom(Pchar(UserDefineHotKey))-$C000);
