In Windows 8 and Windows 10 before Anniversary update it was possible to show touch keyboard by starting
It no longer works in Windows 10 Anniversary update; the
TabTip.exe process is running, but the keyboard is not shown.
Is there a way to show it programmatically?
UPDATE
I found a workaround - fake mouse click on touch keyboard icon in system tray. Here is code in Delphi
UPDATE 2
Another thing I found is that setting this registry key restores old functionality when starting TabTip.exe shows touch keyboard

OK, I reverse engineered what explorer does when the user presses that button in the system tray.
Basically it creates an instance of an undocumented interface
ITipInvocation and calls its Toggle(HWND) method, passing desktop window as an argument. As the name suggests, the method either shows or hides the keyboard depending on its current state.
Please note that explorer creates an instance of
ITipInvocation on every button click. So I believe the instance should not be cached. I also noticed that explorer never calls Release() on the obtained instance. I'm not too familiar with COM, but this looks like a bug.
I tested this in Windows 8.1, Windows 10 & Windows 10 Anniversary Edition and it works perfectly. Here's a minimal example in C that obviously lacks some error checks.
Here's the C# version as well:
Update: per @EugeneK comments, I believe that torvintorvin
tabtip.exe is the COM server for the COM component in question, so if your code gets REGDB_E_CLASSNOTREG , it should probably run tabtip.exe and try again.

The only solution I've found to work is by sending PostMessage as you've mentioned in answer 1. Here's the C# version of it in case someone needs it.

I detect 4 situations when trying to open Touch Keyboard on Windows 10 Anniversary Update
1 - nothing to do
2+3 - activating via COM
4 - most interesting scenario. In some devices starting TabTip process opens touch keyboard, on some - not. So we must start TabTip process, wait for appearing window 'IPTIP_Main_Window', check it for visibility and activate it via COM if nessesary.
I make small library for my project, you can use it - osklib

I had the same problem too. It took me much time and headache, but Thanks to Alexei and Torvin I finally got it working on Win 10 1709. Visibility check was the difficulty. Maybe The OSKlib Nuget could be updated. Let me sum up the complete sulotion (For sure my code has some unnecessary lines now):

There is still some mystery about how the touch keyboard is set visible by Windows 10 Anniversary Update. I'm actually having the exact same issue and here are the lastest infos i've found :
Please note that this registry value is the 'Show touch keyboard on desktop mode if there is no attached keyboard' option in Windows parameters > touch
So far tested on 4 different computers and i'm unable to get something working fine on all..

The problem seems to be with setting of Windows OS. I have faced same issue with the app I was developing. With Windows 8 and 10 (before update) code that called keyboard worked fine, but after update failed to work. After reading this article, I did following:

Implementing the IValueProvider/ITextProvider in your control is a correct way to achieve this, as described here: https://stackoverflow.com/a/43886052/1184950

The following code will always work since it uses latest MS Api
I put it into a dll (Needed for a Delphi project) but it is a plain C Also useful for obtaining the keyboard size and adjusting application layout

In Win10 Ver 1803, DesktopMode, there is no reliable way to
toggle the 'Touch Keyboard' on|off [ ITipInvocation.Toggle() ]; nor can you reliably discover if it's 'up' ( on screen ) [ IFrameworkInputPane.Location() ]; both routines fail randomly.
Instead, ensure that 'TabTIP.EXE' and '..InputApp.EXE'
only run when the keyboard is 'up' ( on screen ).
To toggle the keyboard on and off ( from X.CPP in Jeff-Relf.Me/X.ZIP ):

Laptop is a Dell 5510, similar to XPS 15. I updated all drivers and firmwares using Dell support site downloads. Also Windows 10 is fully updated.
The issue is that after resuming from sleep the keyboard doesn't work. If I have an external keyboard connected it works normally but the laptop keyboard doesn't. One thing I noticed is that the keyboard backlight works and the keys to change the screen brightness still work, also using the function key works because it toggles the brightness keys. I tried reinstalling all the chipset drivers and the bios. Also uninstalled the USB Root device and restarted. In device manager unselected the 'allow windows to turn off this device to save power' as indicated in other forums. No luck with anything here. Everytime after resuming from sleep, keyboard won't work. Suggestions? Comments are closed.
