i don't know the following code, anyone help!~ (vb)

 If (Not ID.IndexOf("\") = -1) Then
                    arrID = Split(ID, "\")

                    If UBound(arrID) > 0 Then
                        m_DebugID = arrUserID(UBound(arrID))
                        Session("ID") = m_DebugID

uBound?

Hi,

UBound function Returns the highest available subscript for the indicated dimension of an array.

Parameters:

      Array

          Required. Array of any data type. The array in which you want to find the highest possible subscript of a dimension.

     Rank

         Optional. Integer. The dimension for which the highest possible subscript is to be returned. Use 1 for the first dimension, 2 for the second, and so on. If Rank is omitted, 1           is assumed.

Return Value:

          Integer. The highest value the subscript for the specified dimension can contain. If Array has only one element, UBound returns 0. If Array has no elements, for example if             it is a zero-length string, UBound returns -1.

for my coding provided on the first post.

here is different cases, what is the result of Session("ID")??

case 1:

if i set ID="aaaa\bbb";

what is the result of Session("ID")?

is Session("ID")="bbb"?

case 2:

if i set ID="aaaa\bbb\ccc";

what is the result of Session("ID")?

is Session("ID")="ccc"?

ubound to return the highest subscript that means the highest index of array it returns????

If (Not ID.IndexOf("\") = -1) Then
                    arrID = Split(ID, "\")

                    If UBound(arrID) > 0 Then
                        m_DebugID = arrUserID(UBound(arrID))
                        Session("ID") = m_DebugID

anyone answer me?

Hi,

As others mentioned, The function UBound returns the highest available subscript for the indicated dimension of an array.

If arrays like below.

Dim arrayTest1 As String() = New String() {"a", "b", "c"}
Dim arrayTest2 As String() = New String() {"1", "2", "3", "4"}

Then UBound(arrayTest1) is 2, UBound(arrayTest1) is 3. If we get value by the subscript.  arrayTest1(UBound(arrayTest1)) is "c" and arrayTest2(UBound(arrayTest2)) is "4".

Hope this helps. Thanks.

 

Best Regards!
