Hey! I'm dynamicly creating listboxes in my program and i want to do something with them in another method but it gives me the NullReferenceException exception. What should i do? public void newTabButton_Click(object sender, EventArgs e) { TextBox textBoxJan = new TextBox(); textBoxJan.KeyDown += new KeyEventHandler(textBoxJan_KeyDown); ListBox LBJan = new ListBox(); tabControl1.TabPages.Add(tabPage); tabPage.Controls.Add(LBJan); tabPage.Controls.Add(textBoxJan); } public ListBox LBJan; public Label sumLabel; public void textBoxJan_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { if (sender is TextBox) { TextBox textBoxJan = (TextBox)sender; LBJan.Items.Add(textBoxJan.Text) } } }

Hello! So i'm writing a program that tests your math knowledge. I am a begginer in programming and i need help with a problem. How can i repeat a method 10 times. This is how my method that i want to repeat looks like: public static void Deljenje () { Random numGen = new Random(); int num01 = numGen.Next(1, 21); int num02 = numGen.Next(1, 11); Console.WriteLine(num01 + "/" + num02); int answer = Convert.ToInt32(Console.ReadLine()); if (answer == num01 / num02) { Console.WriteLine("Bravo!"); } else { int responseIndex = numGen.Next(1, 4); switch (responseIndex) { default: Console.WriteLine("To pa ni prav!"); break; case 1: Console.WriteLine("Bolj se potrudi!"); break; case 2: Console.WriteLine("Poskusi znova!"); break; } } } Ps. just ignore the values in Console.Writeline - s. i'm slovenian Thanks
