How to make a function for keystrokes

[Mikelin]

I have the following code, all I am trying to do is to pass down a keystroke to this function so that it does the keystroke. How do I use a variable of some kind in the function? I know a char doesn't work.

thanks!


void send(char a)
{
INPUT ip;
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = 0;
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;

//Press the "V" key
ip.ki.wVk = a;
ip.ki.dwFlags = 0; // 0 for key press
SendInput(1, &ip, sizeof(INPUT));

// Release the "V" key
ip.ki.wVk = a;
ip.ki.dwFlags = KEYEVENTF_KEYUP;
SendInput(1, &ip, sizeof(INPUT));

}

I know, it's not the direct answer to your question. Hope you can find it out with autoit

Please use code tags.

ip.ki.wVk = a;

requires a virtual key code, not a character.

Luckily for us, the virtual key code for the character 'A' is the same as the ASCII code for 'A'.

Thus, all you need to do is make the character uppercase through the use of the toupper function.
