Changing a Control's Font Size at Runtime in VB.NET

If you have a control that is using a font with size 8.25 (which was defined at design-time), then at runtime you want to change it to a different size (such as 12), you cannot simply say:

ctrl.Font.Size = 12 (this will not work - Property Size is Read-Only)

However, you can replace the whole font:

ctrl.Font = new Font(ctrl.Font.FontFamily, 12, ctrl.Font.Style)

For more info and examples in C#, see: http://bytes.com/forum/thread261450.html
