Calling the on-screen keyboard using a button in C#

Question

I am creating a windows application using C#, where in a button on the GUI when clicked, should display the on-screen keyboard.

Would appreciate if any help is granted. thanks.

Also, since I am mostly using Emgu Cv library for the rest of my app, Can we simply use it for calling the On-screen keyboard?

`Process.Start("osk.exe");` should work on all Windows systems. — Cody Gray - on strike, Jan 10 '12 at 08:20
@CodyGray unfortunately not working when building for x86 (I am forced due to GeckoFx) — oo_dev, May 26 '20 at 07:07

In C#, you can simply write the following line of code to invoke the on-screen keyboard application that comes with Windows:

System.Diagnostics.Process.Start("osk.exe");

On Windows 10 you need to change Build settings to perform target in x64 like @Hassan Rahman said – john.kernel Jun 28 '18 at 07:23

For Windows 10 x64, You have set the project build to x64 as shown in image.

Process process = Process.Start(new ProcessStartInfo(
            ((Environment.GetFolderPath(Environment.SpecialFolder.System) + @"\osk.exe"))));
