What's not working about it? Please be more specific in your postings so that we don't have to read your entire code to find out - that ultimately benefits us all 
I presume you do have a line similar to Do While Not rst.EOF to match the closing Loop statement? Good.
Be wary of compound or statements like this:
if isnull(rst("reportMonth"))= true or len(rst("reportMonth"))=0 then
because you may find that BOTH sides of the or may be evaluated before the result of the If is resolved. It could be that either the LHS or RHS of the or is throwing an exception?

Good morning to everyone!
I have created an Udp Class to handle UDP communication (using the UdpClient class provided by the Framework).
To correctly handle the receival of data I have created a new thread (this is also shown in the many examples found on the internet). My problem is: if I try to assign the data received to a textbox (for example) an exception is raised since the window (the textbox) was created in a different thread. This is not a big problem (the exception is raised only at design time and not at runtime) but I'd like to know if there is a way to avoid this problem.
Thank you!

Hi im fairly new to VB.NET or programming for that matter. I was wondering how I could pass data from one form to the other with additional data from a database.
Here's the case...I've a web app that displays various company department in which when i click on my view button it shows the machines that are assigned to them. Now here is my problem...every machine displayed on my datagrid has a detail link which i would hopefully like to show the details of the machine including serial number, date of purchase, supplier, product ID etc. Only...im not sure how to do it. Logically i think i would have to use a primary key ("Prodict ID") then use it as reference on what the other lbl boxes would display.
Could someone please give me a headstart on how to go about doing this. Thanx for all your help and suggestions!

Create the corresponding object variables in the second form,
pass as a parameter to that form before loading the form,
Perform the related operations on 'ON-LOAD' event

On-Load....oh Page_Load. Yeah I've figured then pass each label as a parameter. Wow thanx! This'l be one hell of a query...

You can pass the product ID on the URL to a page that calls a stored procedure to get the details for that one product.

Woah ur also post here at VB.NET. U must really be good!

Kampai!!!

LOL - actually, I've never used VB.NET, and I doubt I ever will. But I know enough about the framework, and questions like this one are really language neutral, so I keep an eye out here as well.

I'm not sure how you mean ? I would be inclined to turn all those labels into a control. I'd also be inclined to have a class which defines one of these objects and can read it's properties from the database when passed an ID for either a constructor or a static create method. Then your control sets each label, one by one ( the only way it can be done ), getting the properties from a class. The class fills those properties from a database call. And all your main page does is pass an ID off to the control.
Sorry, does that sound confusing ? Let me know if you need more info.

Yeah...had to read your post bout 3 times LOL!. But that was exactly wat i was looking for. I was searching for a quick way which sets all labels automaticaly without having to set them one by one. Thanx chris!

I'm making some application, and I'm using a collection of objects to handle the data, the objects inside the collection has some other collections as parameters, I'd like to know if there's a way to create a databind to a datagrid of some information contained in the objects inside my collections, any help will be greatly appreciated.

Here are some hints that may help you solve your problem.
When you create a class that with several Set/Get Properties defined and then create an array of objects of that class then you can set your datasource to your and the datagrid shold have complete access to all the properties of your class or you can add a DataGridTableStyle to your datagrid and add DataGridTextBoxColumn for some of the properties of your class.
Since you can populate a main datagrid then you can populate another datagrid that show the collections that are inside your first collection.
Hope this makes sense.

Hey sorry about the late answer, actually I couldn't make it work binding the objects so i had to find an alternate way, but actually if you have a reference about this I'd really appreciate if you could pass it to me, cause I'm still interested about this.
thanks

Hi all
I want to learn VB.Net. If anybody know the website addresss for vb.net tutorial which is best for beginners.
Thanks

I recommend this site, and learning C# instead. However, MSDN has heaps of info on both, and so does this site.

Hi I don't know at what level you are looking for but there is this website that gives you an over view of vb.net. This website gives you a basic idea I am beginner and I tried many websites and books and found this reasonable.
check it out www.startvbdotnet.com.
Good luck

I have connected up my database but when I preview Dataset in the OLEDataSet Adapter tool in VB, it shows no data and says 0 rows. I know it's connected because it is able to show the table headers.
It's choking on the line: OleDbDataAdapter1.Fill(DataSet11.Pub_Points) with the error: "An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll" (which I suspect is a rather useless message for the purpose of debugging).
DataSet11.Pub_Points is the only option Datasource available in the DataSource property of the control.

Hi there can anyone help me please, I can export a 'Dataset' to XML but can anyone tell me how to export a Datagrid please... I use VB.NET

Considering a DataGrid isn't serializable and doesn't contain any "data", what you want doesn't make any sense. What exactly are you trying to do?

ok re-wording this.
1. this is a web application.
2. there are 2 pages. page1.aspx and page2.aspx
3. I'm using sql server.
I am using 1 table in the server to collect all the data. When the user logs in they are taken to the first page(page1.aspx) here they are asked to input some of the data. The application creates a new record with a unique identifier called form_id. The user inputs the data and is then taken to page2.aspx. Here the user is to update the new record they just created but i can't seem to be able to tell the application to go to the database and retrieve the last record entered.

i don't understand at all dude, you really need to explicit your question more than this, and use more context word. what is a page ? what do you try to do ? what is the relation with the database and your program ? what database do you use ? etc...
