Hi,

This might be a really basic question, so apologies in advance!!

I've got a function that needs to return 3 values (Outputs from a stored
procedure), but I can only seem to retrieve 1 of the values on my ASP page.
Is it possible to do this using my code below? I've managed to return all 3
values as a string...

Return CInt(sqlParam30.Value) & "|" & CInt(sqlParam31.Value) & "|" &
CInt(sqlParam32.Value)

....but I don't really want to have to manipulate the string on the
receiving page.

Here's my code:

code extract -----------------------

Dim sqlParam30 As SqlParameter = New SqlParameter("@intCustomerID",
SqlDbType.Int, 4)
sqlParam30.Direction = ParameterDirection.Output
myCommand.Parameters.Add(sqlParam30)

Dim sqlParam31 As SqlParameter = New SqlParameter("@intInvoiceID",
SqlDbType.Int, 4)
sqlParam31.Direction = ParameterDirection.Output
myCommand.Parameters.Add(sqlParam31)

Dim sqlParam32 As SqlParameter = New SqlParameter("@intDeliveryID",
SqlDbType.Int, 4)
sqlParam32.Direction = ParameterDirection.Output
myCommand.Parameters.Add(sqlParam32)

'## Open the connection and execute the Command
MyConnection.Open()
myCommand.ExecuteNonQuery()
MyConnection.Close()

'## Return the ID's
Return (sqlParam30.Value)
Return (sqlParam31.Value)
Return (sqlParam32.Value)

end extract ---------------------------

Regards,

Jason

one solution is to pass in the variables byRef and set them in the
function

e.g.
dim int1 as int32
dim int2 as int32

myFunc(int1, int2)

function myFunc(byRef parm1 as int32, byRef parm2 as int32)
parm1 = 3
parm2 = 7
end function

You can create a class with 3 fields, 1 for each value, in that way you
can handle each value...

You could do it by=20

1 - Defining an enum and returning that enum

Enum myReturnValues
Value1 as Integer
Value2 as Integer
Value3 as Integer
End Enum

Function YourFunction() as myReturnValues

2- Return an array

Function YourFunction() as Integer()

3 - By using ByRef Values

Sub YourFunction (ByRef Val1, ByRef Val2, ByRef Val3)

Sorry, where I said "Enum" I meant Structure

So:

Structure myReturnValues
Value1 as Integer
Value2 as Integer
Value3 as Integer
End Structure

You've got 3 basic options:

    - Use globally scoped variables
    - Pass in a struct Type with 3 fields
    - Pass fields in ByRef

Bear in mind with the first option that I mentioned, that you should
always try to minimize variable scoping so that would be the least
desirable.
