SendKeys to another application's form

Question

I created a Process. That one has a MainWindow I want to SendKeys.Send("+F") (CTRL+F) to, but I don't know how to do this.

So how is this done?

Answer 1

For Ctrl key you need to precede the key code with ^. something like:

SendKeys.Send("^F");

Answer 2

You'll need something like the following to set focus to an external window:

public class Form1 : Form
{
    [DllImport("user32.dll")]
    static extern bool SetForegroundWindow(IntPtr hWnd);

    private void button1_Click(object sender, EventArgs e)
    {
        Process[] process = Process.GetProcessesByName("notepad");

        if (process.Length > 0)
            SetForegroundWindow(process[0].MainWindowHandle);
    }
}
