AutoCAD .NET :: How To Set Color Index And Layer Of Newly Created Dimension Style

I'm having a bit of a problem struggling with creating new dimension style using vee bee dot net, in AutoCAD 2010 environment. I am particularly trying to figure out how to set the newly created dimension style to color white, and to assign it a specific layer (for example, a layer called "test"). What the code syntax is to accomplish this?

I post the code below for what I have done thus far:

Public Shared Sub addDimensionStyle(ByVal strDimStyle As String)
Dim acDb As Database = HostApplicationServices.WorkingDatabase
Using acTrans As Transaction = acDb.TransactionManager.StartTransaction()
Dim dimTbl As DimStyleTable = acDb.DimStyleTableId.GetObject(OpenMode.ForWrite)
Dim dimTblRec As DimStyleTableRecord = Nothing
