Windows 10周年版显示触摸键盘(TabTip.exe)
Windows 10周年版显示触摸键盘(TabTip.exe)
提问于 2016-08-04 17:46:58
在Windows 8和Windows 10周年更新之前，可以通过启动显示触摸键盘
C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe它不再适用于Windows 10周年更新；TabTip.exe进程正在运行，但没有显示键盘。
有办法以编程方式显示吗？
更新
我找到了一个解决办法-假鼠标点击触摸键盘图标在系统托盘。以下是Delphi中的代码
// Find tray icon window
function FindTrayButtonWindow: THandle;
var
ShellTrayWnd: THandle;
TrayNotifyWnd: THandle;
begin
Result := 0;
ShellTrayWnd := FindWindow('Shell_TrayWnd', nil);
if ShellTrayWnd > 0 then
begin
TrayNotifyWnd := FindWindowEx(ShellTrayWnd, 0, 'TrayNotifyWnd', nil);
if TrayNotifyWnd > 0 then
begin
Result := FindWindowEx(TrayNotifyWnd, 0, 'TIPBand', nil);
end;
end;
end;
// Post mouse click messages to it
TrayButtonWindow := FindTrayButtonWindow;
if TrayButtonWindow > 0 then
begin
PostMessage(TrayButtonWindow, WM_LBUTTONDOWN, MK_LBUTTON, $00010001);
PostMessage(TrayButtonWindow, WM_LBUTTONUP, 0, $00010001);
end;更新2
我发现的另一件事是，在启动TabTip.exe时，设置此注册表项将恢复旧的功能，显示触摸键盘。

好的，我反向设计了资源管理器当用户按下系统托盘中的按钮时所做的事情。
基本上，它创建一个没有文档化的接口ITipInvocation的实例，并调用它的Toggle(HWND)方法，将桌面窗口作为参数传递。顾名思义，该方法根据当前状态显示或隐藏键盘。
请注意，资源管理器在每次单击按钮时都会创建ITipInvocation实例。因此，我认为不应该缓存实例。我还注意到，资源管理器从不对获取的实例调用Release()。我不太熟悉COM，但这看起来像个bug。
我在Windows8.1、Windows 10和Windows 10周年版中测试了这一点，它运行得很好。在C中，这里有一个很小的例子，它显然缺少一些错误检查。
#include <initguid.h>
#include <Objbase.h>
#pragma hdrstop
// 4ce576fa-83dc-4F88-951c-9d0782b4e376
DEFINE_GUID(CLSID_UIHostNoLaunch,
0x4CE576FA, 0x83DC, 0x4f88, 0x95, 0x1C, 0x9D, 0x07, 0x82, 0xB4, 0xE3, 0x76);
// 37c994e7_432b_4834_a2f7_dce1f13b834b
DEFINE_GUID(IID_ITipInvocation,
0x37c994e7, 0x432b, 0x4834, 0xa2, 0xf7, 0xdc, 0xe1, 0xf1, 0x3b, 0x83, 0x4b);
struct ITipInvocation : IUnknown
{
virtual HRESULT STDMETHODCALLTYPE Toggle(HWND wnd) = 0;
};
int WinMain(HINSTANCE hInst, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
HRESULT hr;
hr = CoInitialize(0);
ITipInvocation* tip;
hr = CoCreateInstance(CLSID_UIHostNoLaunch, 0, CLSCTX_INPROC_HANDLER | CLSCTX_LOCAL_SERVER, IID_ITipInvocation, (void**)&tip);
tip->Toggle(GetDesktopWindow());
tip->Release();
return 0;
}下面也是C#版本：
class Program
{
static void Main(string[] args)
{
var uiHostNoLaunch = new UIHostNoLaunch();
var tipInvocation = (ITipInvocation)uiHostNoLaunch;
tipInvocation.Toggle(GetDesktopWindow());
Marshal.ReleaseComObject(uiHostNoLaunch);
}
[ComImport, Guid("4ce576fa-83dc-4F88-951c-9d0782b4e376")]
class UIHostNoLaunch
{
}
[ComImport, Guid("37c994e7-432b-4834-a2f7-dce1f13b834b")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface ITipInvocation
{
void Toggle(IntPtr hwnd);
}
[DllImport("user32.dll", SetLastError = false)]
static extern IntPtr GetDesktopWindow();
}更新： per @EugeneK注释，我认为tabtip.exe是所讨论的COM组件的COM服务器，所以如果您的代码获得了REGDB_E_CLASSNOTREG，它可能会运行tabtip.exe并再试一次。

我也有同样的问题。这花了我很多时间和头痛，但多亏阿列克谢和托文，我终于让它在101709胜利。能见度检查是很困难的。也许OSKlib Nuget可以被更新。让我总结一下完整的润肤液(当然，我的代码现在有一些不必要的行)：

我找到的唯一可行的解决方案是发送PostMessage，就像您在回答1中提到的那样。
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
private static extern IntPtr FindWindow(string sClassName, string sAppName);
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string lclassName, string windowTitle);
[DllImport("User32.Dll", EntryPoint = "PostMessageA")]
static extern bool PostMessage(IntPtr hWnd, uint msg, int wParam, int lParam);
var trayWnd = FindWindow("Shell_TrayWnd", null);
var nullIntPtr = new IntPtr(0);
if (trayWnd != nullIntPtr)
{
var trayNotifyWnd = FindWindowEx(trayWnd, nullIntPtr, "TrayNotifyWnd", null);
if (trayNotifyWnd != nullIntPtr)
{
var tIPBandWnd = FindWindowEx(trayNotifyWnd, nullIntPtr, "TIPBand", null);
if (tIPBandWnd != nullIntPtr)
{
PostMessage(tIPBandWnd, (UInt32)WMessages.WM_LBUTTONDOWN, 1, 65537);
PostMessage(tIPBandWnd, (UInt32)WMessages.WM_LBUTTONUP, 1, 65537);
}
}
}
public enum WMessages : int
{
WM_LBUTTONDOWN = 0x201,
WM_LBUTTONUP = 0x202,
WM_KEYDOWN = 0x100,
WM_KEYUP = 0x101,
WH_KEYBOARD_LL = 13,
WH_MOUSE_LL = 14,
