Albeit new to VB.NET, I've done this several times before, but today
I've run into an interesting problem. I am trying to loop through a
datareader and display the data in a spreadsheet. So far, I only get 1
row to display. (I know it has multiple rows)
Here's the code for the loop:
xlRow = "4"
With reader
.Read()
Do While .HasRows
xlSheet.Cells(x lRow, 1) = .Item("emp_name ")
xlSheet.Cells(x lRow, 2) = .Item("dt_filed ")
xlSheet.Cells(x lRow, 3) = .Item("dt_check ")
xlSheet.Cells(x lRow, 4) = .Item("g_type")
xlSheet.Cells(x lRow, 5) = .Item("g_desc")
xlSheet.Cells(x lRow, 6) = .Item("totPay")
xlSheet.Cells(x lRow, 7) = .Item("dept")
xlSheet.Cells(x lRow, 8) = .Item("union_na me")
xlRow = xlRow + 1
.NextResult()
Loop
End With
reader.Close()
I appreciate any help.

tjonsek,
The NextResult method moves to the next result when you are executing
multiple sql statements.
You probably want something like:
With reader
Do While .Read()
xlSheet.Cells(x lRow, 1) = .Item("emp_name ")
xlSheet.Cells(x lRow, 2) = .Item("dt_filed ")
xlSheet.Cells(x lRow, 3) = .Item("dt_check ")
xlSheet.Cells(x lRow, 4) = .Item("g_type")
xlSheet.Cells(x lRow, 5) = .Item("g_desc")
xlSheet.Cells(x lRow, 6) = .Item("totPay")
xlSheet.Cells(x lRow, 7) = .Item("dept")
xlSheet.Cells(x lRow, 8) = .Item("union_na me")
xlRow = xlRow + 1
Loop
End With
reader.Close()

Let me explain what Kerry did so that you will understand it.
DataReaders moves to the next record everytime you call the Read method.
In your code you have used
Do While .HasRows
Well, the DataReader will keep having Rows, and it will go in an endless
loop
Do this instead
If .HasRows Then
Do While .Read
bla bla bla
Loop
End If

Great. Thanks so much. I've been an ASP coder for a long time, finally
convincing everyone here to switch to .NET, but it's up to me to teach
myself. I'm not familiar with datareaders and only just started
utilizing them. What you said Cyril made sense. Thanks, both of you.

I have 2 dropdowns that are exactly the same and I don't want to re-read

Is there a way to do something like below where I read the data, bind to
depCity1 and then bind to destCity2. I find that the second one always
is blank. I assume this is because the DataReader is read-forward only.

Hi all,
the question I want to ask if the conversion of a DataReader to a Table
looping through the DataReader is better than using the Fill Method of
the DataAdapter... I'm asking because internally the DataAdapter uses
the DataReader... so whats the deal of writing a method that converts a
DataReader into a DataTable ?
Thanks!

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
