Well, you'd use a hashtable, I guess, or build it into a resource file.

Select * from mytable where theword LIKE '%word%'

I think you need to buy a really basic book and work through it. A C# book first, then a SQL one.

I've been searching google thoroughly and haven't yet found anything that does what I need it to do, so I thought I'd ask here. Most of what is out there is software to create (display) a barcode. I want to actually scan the code and convert it to something I can use against my product database.

I have a web application. I want to be able to have the user scan a barcode and then have the scanned code picked up and used by the website. I understand this will require an activeX control. A windows application is not an option. It also needs to support a variety of scanning devices as we don't know what our clients will use to scan the barcodes.

I am not opposed to purchasing a third party solution.

If you have ever done something like this please point me in the direction of example code or third party vendors.

Thanks

I haven't worked with any devices like that for many years but back then the devices actually convert the bar code to a byte sequence which is what they output. You would use the specification for the device to determine the format of the data. Then you have to read from the device using whatever connection it has to the PC. (COM port, USB, etc.)

After further searching I found that Microsoft has their own managed library that handles the device drivers. I think I will see if I can make it work in an activex control.

AJAX New development question.

Hello All,

I am about to start a new web project and would like some advice on the best way to achive my goal.

I want to have a gridview control that displays database information. Lets say all customers from a customer table. Now say the database table (customer) is updated by another user, lets say an new customer is added. I want that new customer to be displayed to all other users with the page open. Without them having to refresh the page.

Can I do this using AJAX?

Can I fire an event when the data access layer method updates the database (say AddCustomer()), and then have each page listing for the update?

Is this possible?

Any help or a point in the right direction will be greatly appriciated.

Thank you in advance

Chris

No. AJAX means your page sends messages to the server, you can do this by polling the server with AJAX, but you'll use a lot of network traffic, you can't fire a message from the server to the client.

Can I not hold the customer data object in the cache? Then have AJAX point to it, so when it is updated it filters over to all the pages?

If I where to add a clock using AJAX it would have to do regular checks with the server!

What cache ? Do you know what AJAX is ?

AJAX doesn't point to anything, except the server it makes calls to.

Correct. That is your only option.

I am binding a Generic List List<products> to an ASP DataGrid and have no problem with the string properties of the Product property items:

<asp:boundfield datafield="ShortName" headertext="Short Name" sortexpression="Program">

The problem I am having is how to bind the Integer properties (fields) to the DataGrid:

<asp: boundfield="" datafield="???????????" headertext="My Integer" ...<br="" mode="hold">
How do I do this?

Thanks,

Steve

Hi group,

I'm using a listbox and the datasource is a collection of the objects.

My code is:

lisbox.Datasource = collection

it's ok.

I'd like to get the object selected in listbox, but i'm not getting.

How I do it?

Sorry my bad English.

Thanks,

Go,

colVOLEndereco = objBLLEndereco.fnListar

If colVOLEndereco.Count > 0 Then
lstEnderecos.DataSource = colVOLEndereco
lstEnderecos.DataTextField = "pstrNome"
lstEnderecos.DataValueField = "pstrIDEndereco"
lstEnderecos.DataBind()
end if
End Sub

Sub Two() - Called on postback

Dim colVOLEndereco As Collection

colVOLEndereco = lstEnderecos.SelectedItem

End sub

In sub two, the object selected isn't got. I'd like to put the selected object in colVOLEndereco.

OK?

Is "Sub One()" called during every page load?

You probably only want to call "Sub One()" only on the initial page load, or when the collection has changed.

How are you "filtering" your gridview? Are you passing parameters to a sql query? Or are you trying to use the dataview filter? Try posting your code if you need help.

I didn't get any requirements for the signature
