[英]c# Windows 10 virtual keyboard issues
I have developed ac# code snippet to determine if the virtual (on-screen) keyboard was showing or not. 我已经开发了ac#代码段,以确定是否显示了虚拟(屏幕上)键盘。
The code below worked fine in Windows 7, 8 and 8.1, but in Windows 10, the IsKeyboardVisible
always returns true
... 下面的代码在Windows 7、8和8.1中工作正常,但是在Windows 10中, IsKeyboardVisible
始终返回true
...
public static bool IsKeyboardVisible() {
Process keyboardProc;
UInt32 WS_DISABLED = 0x8000000;
UInt32 WS_VISIBLE = 0X94000000;
int GWL_STYLE = -16;
IntPtr keyboardHandle = GetKeyboardWindowHandle();
bool visible = false;
if (keyboardHandle != IntPtr.Zero) {
UInt32 style = GetWindowLong(keyboardHandle, GWL_STYLE);
// in Win10, this always returns "true", i.e. WS_DISABLED is
//
//visible = ((style & WS_DISABLED) != WS_DISABLED);
// UPDATE: I found this code helping here
visible = (style == WS_VISIBLE);
}
return visible;
}
I used a tutorial on SO, but it's a while ago so sorry for not crediting the author. 我使用了关于SO的教程,但是前一阵子很抱歉,我不相信作者。
Does anyone know about a working code snippet for all recent Windows versions, so I don't have to check the actual OS to switch on the version...? 有谁知道所有最新Windows版本的工作代码段,因此我不必检查实际的操作系统即可打开该版本...?
UPDATE 更新
I found the original post here , which allowed me to correct the code. 我在这里找到了原始帖子 ,这使我可以更正代码。 So now my problem is the same old Win10 issue - I can't show the virtual keyboard using 所以现在我的问题是相同的旧Win10问题-我无法使用
string progFiles = @"C:\Program Files\Common Files\Microsoft Shared\ink";
string keyboardPath = Path.Combine(progFiles, "TabTip.exe");
keyboardProc = Process.Start(keyboardPath);
... Again, is there any "all-platform" code I can use, or what is the suggested approach for Win10? ...同样,我可以使用任何“全平台”代码,或者Win10的建议方法是什么?
UPDATE 2 I found out about issues running a 32-bit application on a 64-bit os. 更新2我发现有关在64位操作系统上运行32位应用程序的问题。 That being said, the error occurs whether I try to run osk.exe
in the System32
or the "sysWOW64` folder... Is there any other way than making a 64-bit release??? 话虽如此,无论我尝试在System32
还是sysWOW64`文件夹中运行osk.exe
,都会发生错误...除了制作64位版本之外,还有其他方法吗???
After much digging about TabTip.exe
, osk.exe
and x86 and x64 compatibility issues, I found a solution by searching the osk.exe
on my system and trying to run each of them. 在深入研究TabTip.exe
, osk.exe
以及x86和x64兼容性问题之后,我找到了一个解决方案,方法是在系统上搜索osk.exe
并尝试运行它们。 I found 4 version the following folders: 我在以下文件夹中找到了4版本:
C:\\Windows\\System32
C:\\Windows\\SysWOW64
C:\\Windows\\WinSxS\\amd64_microsoft...
C:\\Windows\\WinSxS\\wow64_microsoft...
It appears the one in C:\\Windows\\WinSxS\\amd64_microsoft...
works fine (not the other three though)... 似乎在C:\\Windows\\WinSxS\\amd64_microsoft...
工作正常(尽管不是其他三个)...
Given the "amd64_...." folder might not be the same on different machines (I actually checked and they don't match, I didn't search whether this depends on the machine, the windows build or anything else...). 鉴于“ amd64 _....”文件夹在不同的计算机上可能不相同(我实际上检查了它们,但它们不匹配,因此我没有搜索这是否取决于计算机,Windows构建或其他任何内容... )。
So basically I did a small routine to look into WinSxS
folder and returning the very firs occurrence of osk.exe
, which works just fine. 因此,基本上,我做了一个小例程来查看WinSxS
文件夹并返回osk.exe
出现,效果很好。 I also made the code working on a 32-bit OS using a simple OS-architecture test: 我还使用简单的OS体系结构测试使代码在32位OS上工作:
string OSKpath64 = getOskPath(@"C:\Windows\WinSxS");
if (string.IsNullOrWhiteSpace(OSKpath64)) {
OSKpath64 = "osk.exe";
}
string OSKpath32 = @"C:\Windows\System32\osk.exe";
if (!File.Exists(OSKpath32)) {
OSKpath32 = @"osk.exe";
}
System.Diagnostics.Process.Start((Environment.Is64BitOperatingSystem) ? OSKpath64 : OSKpath32);
UPDATE: The confusion with one working and one non-working version within the WinSxS
folder made me nervous. 更新: WinSxS
文件夹中对一个可用版本和一个不可用版本的困惑使我感到紧张。 It works just fine because the amd_..
folder is alphabetically before wow64_...
. 由于amd_..
文件夹按字母顺序在wow64_...
之前, wow64_...
它可以正常工作。
I therefore suggest to add a test in the getOskPath
method to return the first native 64-bit osk.exe
(not the emulated one). 因此,我建议在getOskPath
方法中添加一个测试以返回第一个本机64位osk.exe
(而不是模拟的)。
Using the IsWin64Emulator
method found here , the method looks like this: 使用此处找到的IsWin64Emulator
方法 ,该方法如下所示:
static string getOskPath(string dir) {
string path = Path.Combine(dir, "osk.exe");
if (File.Exists(path)) {
Process p = System.Diagnostics.Process.Start(path);
if (p.IsWin64Emulator()) {
path = string.Empty;
}
p.Kill();
return path;
}
DirectoryInfo di = new DirectoryInfo(dir);
foreach (DirectoryInfo subDir in di.GetDirectories().Reverse()) {
path = getOskPath(Path.Combine(dir, subDir.Name));
if (!string.IsNullOrWhiteSpace(path)) {
return path;
}
}
return string.Empty;
}
Same problem with me, I try all answer here, but it not work. 我遇到了同样的问题,我在这里尝试所有答案,但是没有用。 After finding solution with google, this is is ok. 用Google找到解决方案后,就可以了。
// Step 1: For Load On-Screen Keyboard
