I want to pass optional arguments to build up varios strings, is this
possible?
look at arrTBL(1,3) in the code below:
=============== =============== =============
Public Function arrTBL(Optional ByVal DataSetName As String = "") As
String(,)
Dim DSN As String = DataSetName
arrTBL(1, 1) = "UP_" & Session("mCallC entreID") & "_Results_Daily "
arrTBL(1, 2) = "DailyCallS t"
arrTBL(1, 3) = "INSERT INTO " & arrTBL(1, 1) & "SELECT " & DSN &
".field1 FROM " & DSN & ";"
End function
=============== =============== =============== =
I would like to be able to do this, but the other arrays dont like it,
too many arguments etc..
Is there a way round this? 3 4787
Winshent,
VB.NET is trying to recursively call your routine, rather then treat arrTBL
as a variable.
To avoid the ambiguity this is causing I would define a variable for the
return value, use this value, then return it.
Something like: Public Function arrTBL(Optional ByVal DataSetName As String = "") As String(,)
Dim value(1,3) As String
Dim DSN As String = DataSetName
value(1, 1) = "UP_" & Session("mCallC entreID") & "_Results_Daily "
value(1, 2) = "DailyCallS t"
value(1, 3) = "INSERT INTO " & value(1, 1) & "SELECT " & DSN & ".field1 FROM " & DSN & ";"
Return value
End function
NOTE: The optional parameter has nothing to do with it, try the following:
Public Function arrTBL(ByVal x As Integer, ByVal y As Integer) As
String(,)
arrTBL(1,1) = "Hello!"
End Function
"arrTBL(1,1 )" is treated as a recursive call so you get an error about
"Expression is a value and therefore cannot be the target of an assignment".
Hope this helps

Whinshent,
I can do it in this way, the other way I did not try.
\\\
Dim DSN As String = "whatever"
Dim arrTbl As New ArrayList
arrTbl.Add(New ArrayList)
DirectCast(arrT bl(0), ArrayList).Add( "UP_" & "mCallCentr eID" _
& "_Results_Daily ")
DirectCast(arrT bl(0), ArrayList).Add( "DailyCallS t")
DirectCast(arrT bl(0), ArrayList).Add( "INSERT INTO " & _
DirectCast(arrT bl(0), ArrayList)(0).T oString & _
"SELECT " & DSN & ".field1 FROM " & DSN & ";")
MessageBox.Show (DirectCast(arr Tbl(0), ArrayList)(2).T oString)

I hope this helps?

Jay, i have used your method and it seems to have worked nicely..
Thanks to you both for responding.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
