Examples

The following code example demonstrates how to use the ScrollBars enumeration.To run the example, paste the following code in a form. Call the SetFourDifferentScrollBars method in the form's constructor or Load event-handling method.

   // Declare four textboxes.
internal:
   System::Windows::Forms::TextBox^ vertical;
   System::Windows::Forms::TextBox^ horizontal;
   System::Windows::Forms::TextBox^ both;
