Four Enhanced Textbox Functions!

This code is 4 functions written by myself, to enhance the TextBox and RichTextBox controls. The 4 functions allow you to:Get the line the user's cursor is onGet the total number of lines in the textboxGet the text on the line that the user is onMass remove any number of characters from the textbox!Works great for parsers, or general applications that use multiline textboxes!!Please vote for me! :)
