Opening a form from another

Question

I have some form with a menu when I'm pressing new button I want to show another form. (not a child form!) I have two forms: frmMain and frmSecond How to show the frmSecond?

In frmMain add this method to receive the string: internal void ReceiveString(string s) { // put code in here to save and/or display the string somewhere for example textBox1.Text = s; } In frmSecond add this code to transmit the string (.NET 2.0 or later assumed): frmMain main = (frmMain)Application.OpenForms[frmMain]; main.ReceiveString(someString);

Great! Thank you

Try: frmSecond f2 = new frmSecond(); f2.Show(); If you want frmSecond to maintain input focus until it is closed use ShowDialog() instead of Show().
