I'm trying to make a application where the user can add a treenode to a treeview, and then after that they can add items to a listbox, making those items bound to that treenode? I need to do this for each node they create but I don't know how... I've been googling and reading tutorials on "DataSets", but it's always stuff about online databases

I have 2 applications.
1. THE application
2. Updater
When my app starts it will check if it's the right version with a webservice, if not then it downloads new files and runs the updater. The updater will copy paste the new files overwriting the old ones.At the moment, I am using a xml file to transfer information from the app to the updater like the where the updater has to copy the files to.However, I would like to get rid of this xml file and send this information to the process directly.

I have a form set up that allows the user to do many things to manipulate items. One of the things they can do is replace an item with another. To do so, what I have them do is click the Replace button on the main form. This calls the show of a choose replacement form where there is a grid view containing the replacement options and a Replace and Cancel button. When the user selects a product from the grid, and clicks the replace button, I want the item's ID to be sent back to the main form to be used in the replacement sub.This is what I have:
Main form:
Form Load:
AddHandler replaceComponentForm.Replace, AddressOf Me.Replace
ReplaceButton.Click[code].....
The problem is the events don't seem to be reaching the main form. The replacement form closes, but Replace does not get called in the main form.

When changing selecteditems (the items themselves, not which ones are selected) in a multiselect listbox, sometimes the operation does not happen and items are deselected. Here is a simple example of what I mean, just a form with a multiselect listbox.

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("item at index 0")

Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.

Working with a listbox to send email and I have the ff code -
Dim EmailAddressFrom As String
EmailAddressTo = lstbxEmailAddress.SelectedValue.ToString()
MessageBox.Show("To Address is ", EmailAddressTo)
When I run this, in my message box, I get -
"System.Data.DatarowView" as the title of my message box "To Address is " And when hit F8 to continue debugging I get the ff error msg - "The specified string is not in the form required for an e-mail address."

I've pretty much just started in playing with Visual Basic Studio 2010 and have been using this site for lots of answers so thought I'd join up and harass more directlyI've been trying to move items between two lists, one is databound to a bindingsource, the other isn't. I found out that you can't really move items from databound lists, but you can remove from the datasource instead. This works fine until I want to move the item back - it fills a blank line with seemingly no data.

My application runs on a "server" machine and provides files (10megs - 100megs each) to 8 other computers. Currently this is done using a standard shared folder on all 8 computers and the server simply copies the file to \ComputerNameSharedFolder - and everything is great.However, due to new policies we need to remove all shared folders, so using a simple \ComputerNameSharedFolder is no longer feasible. Therefore I need to find a way for my application to be able to share these files in a safe, secure, and compliant way.There has been talk of using sFTP which would require each system to have an sFTP server running at all times (controlled by the application somehow), or also SSL was talked about as it can be integrated into the application easily, etc...

I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox. I have the DisplayMember set to FirstName, and obviously only display the First Name of the contact in the ListBox. Is there an easy way to change it so that it displays the First and Last names? I can't change the binding because I need it to get the ID of the record selected.Here's the basis of my code...

I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

I have a table in my database. I have an import routine which reads rows from and XML file. It first loops through my existing table to see if the row exists using a date and store code column as a unique id. It all works fine until this senario occurs.First file is read in and a new row is added for 01/03/2011, store code 100. The second file is read in which also has a row with 01/03/2011, store code 100. But when I loop through it does not find the row I just added so it adds it again.The only solution I can think of is to re-populate the local table everytime I add a new row but this will have a massive amount of over heads.If I add a row to an existing dataset surely if I loop through that dataset I should come across it.

If i build the app and puts it on another computer and tries to connect to the db it says it can't find the file who where referencing to MySQL.Data??
Shouldn't that reference dll follow with the program in the programs exe or something?

I am working in vb2008. How to store Class/Structure instance data into a database as single objects.
SomeClass
.name
.address
.age
.etc
Say I have a hundred instances of "SomeClass" stored with data. Is there a way that I can store each of my hundred instances as a hundred objects to a hundred Access database records. I am trying to avoid having to mirror my class structure into a datatable and treat each instance as a single object which can be stored into a single database column name.
