Hi Adil,

Please take a look at the Data Types Used by Excel article in MSDN. Available data types are listed in the spreadsheet.

i. Use defensive Programming.
ii. Use Object in the Arguments of the Function. Object get any type in dotnet.
iii. Define variable of type ADXExcelRef.
iv. Set variable to Object.
v. the function demonstrate this is:

Public Shared Function Sequence(ByVal arg As Object) As String

Dim str As String = vbNullString
Dim rng As ADXExcelRef

Dim TopColumnValue As String = vbNullString
Dim TopLeftColumnValue As String = vbNullString
Dim CurrentColumnVAlue As String = vbNullString

Try

If TypeOf arg Is ADXExcelRef Then

rng = CType(arg, ADXExcelRef)

If rng IsNot Nothing Then

... TO DO...


End If

End If

Catch ex As Exception
MsgBox(ex.Message.ToString)
End Try

Return str

End Function
