I have a combobox populated with 1300+ names. I want to make it easier for my data entry clerk to enter the last name, and it pulls from the list.
I found the following link:
http://support.microsoft.com/default.aspx?scid=kb;en-us;320107[^]
This knowledgebase article lists some code that doesn't work the way I need it. The code searches in the list for a name that matches and if so, it selects it. If not, it allows the client to type in a new name.
I need code to select only from the list and if you type something not on the list and backspace to retype, it picks up again.
Does anyone have some code suggestions or enhancements to this code that might help?
Any suggestions are appreciated.

For anyone who is interested, I found some good advise and samples that I used from gotdotnet.com. Here is the link:

Hi all,
Im having a bit of trouble displaying data from a field into a textbox. I should mention that this is a web application that is doing a select statement and then populating the data into a textbox. The problem is that one of the fields has spaces in it.
If i try to display the data into a text box using this code:
My Label
Only the first word of the sentence is coming up. Is there a reason for this and a way around it? Any help would be greatly appreciated. Thanks

Your question really belongs in the ASP.NET Forum since it really has nothing to do with VB/VB.NET.
Only the first word is showing up because once objRS() is evaluated, the HTML becomes:
<input TYPE=text NAME=txtield_nameF SIZE=50 VALUE=Whatever objRS returned here>
You might want to type enclosing the objRS() code in quotes:
<input TYPE=text NAME=txtield_nameF SIZE=50 VALUE="Whatever objRS returned here">
But, then again, I'm no expert in ASP...

Hi there can anyone provide me with code or example project that will allow me Logon Via a remote database or txt file e.g. Server sits in London and the Client sits in Edinburgh, I wont to enter a Username and Password in Edinburgh and the credentials are verified from a database or txt file in London.
Iam using VB.NET
Thanks in advance.
Knowledge is Knowledge but finding Knowledge is a more powerful Knowledge.

Once the Username and Password has been verified from a database or txt file the logon form will close and allow you to continue with app.

Once again, what is the client logging into? An SQL Server, Windows Server, Linux box, what?

I think you thinking too deep, once i type in a username and password they are sent via TCP/IP or other method to the server(PC) were the usernames and passwords are stored if there is a match then the logon form will close.

Actually, you're not thinking deep enough. Are you connecting to a WebService, HTTP site, SQL Server, or are you going to be writing the Authentication Service for the server machine?
Each method has a radically different method of connection and communication. So, YES, it DOES matter!

If I cant explain it this time then forget it. Imagine 2 PCs on a LAN - PC1 has a text file containing a list of usernames and passwords with some sort off server app that reads that text file, PC2 has some sort of client app installed which has 2 text boxes one for Username and one for Password and a login button, when you enter a username and password and click login its send the username and password to PC1’s server app that app then reads the text file to see if the username and password exists the answer is then sent to PC’2 client app and a message box pops up says “User Found” or “User not Found”.

And that application is __________?
Is this server application something you wrote or something someone else wrote and your trying to call it?

Finally! An answer we can use! I asked you a couple of posts ago:
are you going to be writing the Authentication Service
for the server machine?
and you never answered the question. Up until now, you never said if it was a component that some else wrote and your trying to use or if it was a component that you want to write. So, yes, your going to write both the server and the client pieces.
There's a bunch of different ways you can do this. But, what is going to work for you could be complicated by the path to the authentication server.
If your going to go over the Internet, you're undoubtedly going to go through a couple of firewalls, in which case a Web Service would be your best bet to get through those walls.
If your staying inside the company network, you could also run into firewalls that will can block you, especially between cities/sites like you are. Again, a Web Service would work, but .NET Remoting is also a possbility if your network won't prevent you from doing this. .NET Remoting will at least let you pick the ports you want to use, whereas WebServices run over standard HTTP.
Try reading Remoting and XML Web Services in Visual Basic .NET[^] for an introduction to both and see what you think.

You have described IIS on the server side, and any web browser on the client side.

Uhhhh.... WHAT?

e.g. Server sits in London and the Client sits in Edinburgh, I wont to enter a Username and Password in Edinburgh and the credentials are verified from a database or txt file in London.
That sounded to me like he was describing an ASP.NET application. IIS for the server and a webbrowser for the client.
I think I hit reply on the wrong post.

i had downloaded "Instrumentation Widgets 3.0", added it as reference and set it as component in my vb.net web application.However the component appears in the toolbox in disabled form,how do i enable it?
Instrumentation Widgets is written in c#, windows based application.

Will it work in a Web Form? Or is it for Windows Forms applications only?

actually...i'm new to this domain....though it is written in windows form application,cldnt i make it work in web form based application?this is my query?

Nope. It must be completely rewritten to work in a web page. Since the browser environment is very restricted and communication with whatever your monitoring is slow, there's little chance, if any, of this ever happening.
