  Problem with Array

  Feb 09, 2012 05:22 PM|LINK

  Hello Everyone and thanks for your help in advance.  I am trying to load an array from a dataview using the following code:

        

  Public Queue As String() = Nothing

          Dim Patients As DataView

          Dim Patient As DataRowView

          Dim QueueCounter As Integer = 0

          For Each Patient In Patients

                  Queue(QueueCounter) = Trim(Patient("Ins1CertNmbr").ToString)                

                  QueueCounter = QueueCounter + 1  

           Next

  However, I am receiving an error message of not set to an object.  I ahve verified that the datacolumn is not NULL, so that is not the issue.  I'm not sure why this error is happening.

  You need to initialize the Queue array. Currently you've set it to Nothing.

  Along the lines of what Metal said, you can set the string array to your dataview count -1. Something like (providing the dataview is filled already);

  Dim Queue(Patients.Count - 1) As String

  Dim label1 As New Label

  dim c as integer

  c=0

  For Each Patient In Patients

  label1.ID = "Label"& c.ToString

  label1.text= Trim(Patient("Ins1CertNmbr").ToString)  

  c=c+1

  Next

  Here you can get the value by refering the text property of

  label0.text

  label1.text

  label2.text so on....

  try.
