Hello i guess so. but they should have a diffrent NameSpace ;)

Hello, here is another ,its much easier but its only when you are using (RichTextBox). add your items to the ComboBox (1,2,3,4,5) it actually means 1x,2x,3x,4x,5x. Code: private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { richTextBox1.ZoomFactor = float.Parse(comboBox1.Text); } try it Regards Hamza

Hello, actually i dont think its the best. at the texbox's Properties change the "ShortcutsEnabled" to "False" or at runtime txtTrial.ShortcutsEnabled = false; this will prevent the user from copying or pasting
