VS 2008 CheckedListBox Retriving Content?

Jun 2, 2012

I know this is an easy answer but I'm having trouble finding it online.

I'd like to get the content of a CheckedListBox1 (or ListBox) by specifying a position on the list. For example, retrive the content of the 3rd item on the list?

I know CheckedListBox1.text will retrive the current highlighted content on the list.

I thought CheckedListBox1.SelectedItems(2).text or CheckedListBox1.SelectedItems(2) was the solution, but it doesn't work.

Add An SQL Database File Using VS 2005 Getting Error Message Saying Version Of Database Server Not Supported?

May 18, 2009

I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?

Connecting To Database Error

Feb 5, 2009

i am building my first VB.net application with a connection to an Access database. Now, this works fine when I debug, however when I deploy the application I get the error saying "Could not find file", which I assume means i have got one of the publishing settings wrong? I don't think it is a code error because it works when I debug, but if anyone wants to see part of it please let me know.

Error In .NET Database Project

Jun 17, 2009

I'm building a vb.net database program and have run into a small problem that I have not been able to figure out.Imports System.Data Public Class Form1

[Code]...

the line "dataAdapter.Fill(dataSet,"Address") " will cause an error when the program is run. "Syntax error in query. Incomplete Query Clause." is the error shown. If I comment that line out the program runs perfectly. Everything that I have seen (and gone by as a tutorial for Database work) has shown that line of code working fine. have I missed something?

Error Message With Using Database?

Mar 31, 2010

I have this application that updates information to a database. I had it working but whether I have deleted or changed something accidentally I don't know. This is the error that appears:

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.InvalidCastException: Conversion from string "SBS-resources" to type 'Integer' is not valid. ---> System.FormatException: Input string was not in a correct format.

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

I deployed the application and when running the setup file i got the following error :
