' AddCustomProperty
'
' Abstract - This function creates a custom property
' for the shape that is passed in as a parameter.
'
' Parameters
' vsoShape Reference to the Shape object
'
' strLocalRowName Specifies the local name for the row.
' This name will appear in the Custom
' properties dialog for users running
' in developer mode.
'
' strRowNameU Specifies the universal name (NameU)
' for the Custom Property row to be
' created.
'
' strLabelName Specifies the label for the Custom
' Property.
'
' vsoPropType Specifies the type of the value of
' the Custom Property. Not all VisCellVals
' constants are valid for this parameter.
' Only constants that start with visPropType make
' sense in this context.
'
' strFormat Specifies the format of the
' Custom Property.
'
' strPrompt Specifies the prompt for the
' Custom Property.
'
' blnAskOnDrop Specifies the value of the
' Ask On Drop check box of the
' Custom Property.
'
' blnHidden Specifies the value of the
' Hidden check box of the Custom Property.
'
' strSortKey Specifies the value of the
' Sort key of the Custom Property.
'
' Return Value True if successful, False otherwise.
