Hi,

You can use FunctionKeys as shortcuts in your windows application. Just write a KeyDown event for your control and then you match the pressed key

For e.g

C#

if (e.KeyValue >= 112 && e.KeyValue <= 123)
{
MessageBox.Show("You pressed F" + (e.KeyValue - 111).ToString());
} 

or

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
 if (e.KeyCode == Keys.Enter)
  { MessageBox.Show("Enter key pressed"); }
}

Hope this helps !! :)

Hi,
In your form Load event, try it like this:

C#

private void Form1_Load(object sender, EventArgs e)
{
     this.Focus();
     this.KeyPreview = true;
     this.KeyDown += new KeyEventHandler(Form1_KeyDown);
}

void Form1_KeyDown(object sender, KeyEventArgs e)
{
  // Your logic goes here
}

Hope this helps !!
