Sending keys in Windows 10 IoT

0 votes

So, I developed a capacitive I2C keyboard for a Raspberry Pi 2 with Windows 10 IoT, so when my I2C controller detects a keystroke I need to send a key to the current page.

In windows forms I have used:

SendKeys.Send("{ENTER}");

How can I send keys?

Sorry, but it is not allowed in UWP due to some APIs restriction to be called only by user interaction. 

Instead, you can programmatically write text to the textboxes like:

// To simulate key 'A' and 'B'
Textbox1.Text += 'A';
Textbox1.Text += 'B';

// To simulate backspace if Textbox contains any character
if (Textbox1.Text.Length > 0)
{
    Textbox1.Text = Textbox1.Text.Remove(Textbox1.Text.Length - 1);
}

Problem with this snippet is, you can't simulate special key like ALT, CTRL, F1-F12, Shift and WinKey.
