Failing to send key presses to a running process in C#
- by Waffles
I'm using the following code to put the focus on a window (in this case, a notepad window), and sending some key presses to it everytime button 2 is clicked. However, when I press button 2, nothing happens. Can anyone tell my why my sendkeys command is failing?
public partial class Form1 : Form
{
[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
private Process s;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.s = new Process();
s.StartInfo.FileName = "notepad";
s.Start();
s.WaitForInputIdle();
}
private void button2_Click(object sender, EventArgs e)
{
ShowWindow(s.MainWindowHandle, 1);
SendKeys.SendWait("Hello");
}
}
