Are there system-wide enums for such things as the Text Alignment Property?

I'm creating my own textbox activex (... I know, I know everybody has done that). When I add the Alignment property with the wizard, for example, it assigns an integer type. I can change the interface to a more standard drop-down box in the object browser with the following code:
Code:
Public Enum myAlignment
  [Left Justify]
  [Right Justify]
  [Center]
End Enum

Public Property Get Alignment() As myAlignment
But I'm wondering if there is a system enum such as "vbTextAlignment" that I should use instead. This way if VB10 adds new constants to the property (say, [Justified]) I don't have to go back and change my code.

(Aside: Furthermore, by making two activeX controls, I have to be sure that the Public Enums dont conflict. Hence, I have enums "myTextBoxAlignment" and "myLabelAlignment" in two separate activex controls that define the exact same list of constants... messy)

Any help would be appreciated,
Jeff
