I am using VS2010 and I programm in c#.
My application is almost finished and I want to protect it with a 30 days time trail.
I made a little example with just a menuStrip and one menu-item called
"Product Registration". When the user clicks on this item another form called
RegForm appears, where the user can enter a valid serial-number into
a textbox called textBox1 that's on the RegForm. When the user clicks on the
close-button then the validation of the serial-number has to begin.
This is al I got:
public partial class Form1 : Form
RegForm frmRegister = new RegForm();
private void registerProductToolStripMenuItem_Click(object sender, EventArgs e)
if (frmRegister.ShowDialog() == System.Windows.Forms.DialogResult.OK)
Who knows the answer and is willing to help me?
