  Wrong answer. The right to left property doest have anything to do with the entered values and the allow only numeric values propertie doest exist in visual studio 2005

  Hi Kent,
  
  I just wanted to confirm that you shouldn't use RightToLeft property in the TB if you need to right-align your digits.
  This property is intended for right-to-left languages, like Arabic, Hebrew, Urdu and Farsi.

  Register an "Validating" event on TextBox and check in the eventHandler if the value entered is a double. If no, set eventarg "cancel" on true

  I believe it's the way its done. Create a TextBox and set its RightToLeft property on Yes. Allow only numeric enter values (and ".")

  You want it to LOOK the same like the textbox in calculator - then you need RightToLeft property.
  Of course VS doesn't have "allow numeric values" property, you have to validate entered values yourself.
  
  So if you have VS 2005, so it's better you use MaskedTextBox control and properly set it's Mask-property.
