change the value of user Variables in autocad2010

[zhangxinhua789]

HEllo, I want to ask a question of Parametric Drawing about  .net API。

    I define a user Variables in autocad2010(such as variableaa=10),I want to use the variable to drive the dimension of a line。

   Now I want to change the value of  variableaa  through  .net API，can you tell me how to change the value of  variableaa  through .net API? can you tell me the code?

thank you very much!

I think the class "AcDbAssocVariables 、AcDbAssoc2dConstraintGroup、AcExplicitConstraint"  is helpful，but I don't know how to use them。
