How to send scandinavian letters using SendInput

Question

I'm trying to create a virtual keyboard, which simulates keyboard using the SendInput method like this:

        public static void SendKeyDown(System.Windows.Forms.Keys key)
        {
            INPUT k = new INPUT();
            k.type = (int)InputType.INPUT_KEYBOARD;
            k.ki.wVk = (short)key;
            k.ki.dwFlags = (int)KEYEVENTF.KEYDOWN;
            k.ki.dwExtraInfo = GetMessageExtraInfo();

            SendInput(1, new INPUT[] { k }, Marshal.SizeOf(k));
        }

But I cannot find the scandinavian letters Ä,Ö and Å from the Keys -enumeration. How can I send these letters using the SendInput method?

Answer 1

You can send Unicode characters using KEYEVENTF_UNICODE.

k.type = (int)InputType.INPUT_KEYBOARD;
k.ki.wScan = 'ö';
k.ki.wVk = 0;
k.ki.dwFlags = (int)KEYEVENTF.UNICODE | (int)KEYEVENTF.KEYDOWN;
k.ki.dwExtraInfo = GetMessageExtraInfo();

This is more portable than your solution of using Oem3 et al, whose assigned character would vary according to the culture of the platform on which your application is executing.

(Rest of P/Invoke signatures can be found in my other answer.)

Answer 2

Found solution myself:

Oem3 = ö, Oem7 = ä, Oem6 = å
