This particular example is interesting in that we actually have a carnivorous way to get and set double formatted data by decimal as well as a more generic and simple way as string. It is obviously more difficult to calculate or aggregate values from a string representation value such as 6'-4" compared to 76.00 but sometimes the string representation is exactly what you need.
The sample code below demonstrates ho a variable initiated as a DB.Parameter is used to get and set the value from or to a string. The get will retrieve a value of 7'-0" or similarly you can set a value by entering 7'-0"...
Add the following snippet to the clsPara class to access the string values of a double formatted parameter:
''' <summary> ''' This property will return the string structured value for a double rather than a decimal ''' </summary> ''' <value></value> ''' <returns>A String</returns> ''' <remarks></remarks> Public Property DoubleValueAsString As String Get If m_parameter.StorageType = DB.StorageType.Double Then Try ' Returns the human readable string representation of a double Return m_parameter.AsValueString Catch ex As Exception Return "" End Try Else Return "" End If End Get Set(ByVal value As String) If m_parameter.StorageType = DB.StorageType.Double Then Try ' Sets the human readable string representation of a double (7'-0" or 150mm) m_parameter.SetValueString(value) Catch End Try End If End Set End Property
