DataBinding Problem: Index was outside the bounds of the array

Let me preface this with I no very little about basic, im more of a c++ / C# guy myself.

Assuming you are sure there is a populated table in your dataset

Well since its a public variable (i assume that scopes it global) why pass it around in the function calls?
Since the functions would then use the one passedto them instead of the globally scoped one.

Plusyou also passed the object byval, not by reference.... that would also imply you were working on a copy.


so:

 

I'm trying to bind a datatable to my datalist and I keep getting this error.

I've never had this problem before and I've created a simple program to
make sure it's not the server. The problem I'm having is probably related
to the fact that I created my dataset as a public variable and then I made
changes to it in another subroutine. Any advice would be much appreciated.

Here's some pseudocode
'public variable
Dim objdataset as DataSet

Sub buttonClick( , )
'open the database
' fill the dataset
' Send the dataset to DoMore()
DoMore(objDataSet)
Try
DataList1.DataSource=objDataSet.Tables(0)
DataList1.DataBind
Catch
' Error: Index was outside the bounds of the array
End Try
End Sub

sub DoMore(byVal objDataSet as DataSet)
' add rows to the 1st datatable in objDataSet

End sub

 

Thanks but that wasn't the problem
It was a good idea to clean up my
code a bit though. You were right
all I needed was a global variable.

Turned out the problem was in my
function that I call inside my DataList
I have a function that formats image
tags for me if I give it the URL of the
images. The problem was in the code
for that function. The array was set
for four elements and I looped to the
fifth element.

I wish there was a way to avoid setting
the dimensions of an array before you
add elements to it. I can do it but the
trick I use is to first add all of the elements
to a string and then Split the string into
elements of an array. It works but it isn't
very efficient. Any ideas on how to do it?

 

You can use an ArrayList http://abstractvb.com/code.asp?A=1030

The ArrayList will allow you to call '.Add', which I think is what you want to do.

if you want to cast that back to an array just do

Dim myArray() As String

ArrayList.ToArray(myArray)
