Hi
I can't get the MSDN's example for Listbox to work.The example is below. I
get an error in Listbox's sub ListBox1_SelectedValueChanged at row
textBox1.Text = ListBox1.SelectedValue and it happens after the line
ListBox1.ValueMember = "ShortName" is run. The error says Cast from type
'USState' to type 'String' is not valid.
I don't know why the code doesn't work, can anyone please explain what I have to do to make it work.
Thank's
Fia

Hello.
I've read my text book and it tells me how to use stored procedures but it doesn't tell me what they are, how to create them and how to use the values returned. I've looked through the MSDN and maybe I'm typing in the wrong things cause I cant find the information I want. Can anyone help?
What I am after is:-
1. How can I create stored procedures in Access 2003?
2. What do I do with them in VB.NET 2003
A table I have in a data base is called Houses. It contains a house address, phone number etc. How could I use a stored procedure to find a certain address or to find the next auto-number for my primary key field.
Many Thanks
The FOZ

Access doesn't support real stored procedures. It can only handle single statement stored queries, which it called a stored procedure.
A real stored procedure is a set of SQL instructions that manipulates a database, tables, rows, or fields. They can be used to do anything in a database, but especially to perform simplex to very complex database lookups, updates, inserts, or deletes. Stored procedures can return no data, single values, a dataset (records), or multiple datasets (multiple sets of records).

Use "Horizontal Rule" from the HTML section from your toolbox 
or just insert an HR tag in your HTML code as follows
<HR style="Z-INDEX: 108; LEFT: 16px; POSITION: absolute; TOP: 256px" width="100%" SIZE="1">

if you want it not for web but for desktop apps then either use a Group control or a Label control that's been collapsed.
otherwise you could go the complex route and physically draw one using System.Drawing namespace.
hope this helps.

You'll have to get on Adobe's Developer site and look for an Illustrator SDK.
IIRC, Adobe charged $ to subscribe to their Dev site though.
