Parametric Constraints

hi how to create constraints (vertical, horizontal, angular, dimensional) using vba and vb dot net

Parametric Constraints are part of Associative Framework, which does not exposed to outside as COM API. Therefore, you cannot manipulate it with AutoCAD VBA, or VB.NET (or other .NET language, for that matter) via COM API. 

However, there is .NET API available since AutoCAD 2011, and this discussion thread may be of help.
