Question

I’ve seen a lot of times, programas that have something like textbox that is used to get/save the path of something… There’s a button on it and when you click on it opens a prompt for you to select the directory, you know ?
How Could I do that?
I have to read a file.txt, and I need my application to open this file.txt, how I open this “prompt” ? Then I need to save a destination path the same way… Is it actually a textboxor something else?

Thanks

You need to add an OpenFileDialog to your form (MSDN has more info)

This sample should explain it better than I could!

private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = "c:\\" ;
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
openFileDialog1.FilterIndex = 2 ;
openFileDialog1.RestoreDirectory = true ;

if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = openFileDialog1.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}
}
