I am working on making a Windows based application within Visual Basic 2008 Express that could potentially be used for a music school as a project. This application is connected and bound to a Microsoft Access database. Within this application I have a form for adding a new appointment reservation. This form has a combo box that the user can select the lesson type (eg. "I want a piano lesson"). Upon being changed, a list box would be populated with the names of all instructors that have that selection as either their primary or secondary talent.So, my database is bound, the query is written (correctly...i hope), and I don't know how to 1) select the table column that I want displayed in the list box and 2) actually display the query results within the list box. Is this making sense? Probably not, bu

I have this code to return a list of fund sources for our organization.
Dim FundSourceList As New List(Of FundSource)
Dim fs As New FundSource
If results.Count > 0 Then[code].....
The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.
For Each FundSource In FundSources
Debug.Print(FundSource.FundDescription)
Next
So I change the code to this. I moved the creation of the fs variable inside the loop.
Dim results = From result In dsResult.Tables(0) Select result
Dim FundSourceList As New List(Of FundSource)
If results.Count > 0 Then[code]....
This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again?

I do however have a slight background with VBA particularly with MS Access, so I am not completely lost.I am recreating my Access database application in VB.net.I created a new project and added an Access database through the wizard, which automatically created a dataset for the database. On one of my forms I have, esentially, a search form. What I want to happen is have a text box, and as I start typing display a search result from my customers table in the list box under it. So for example, I type "A" and all customer names that start with "A" are displayed in the list box.I continue typing with a "p" (full string is now "Ap"), then all customer names that start with "Ap" are displayed and so on...
I did search on my own first before posting this and found a few tips but cant really get it to work the way I want. This is what I have...

The item in red is where i get an error. it sucessfully builds and i open the find form enter a last name that I know is in the customers table, but I get the error "Cannot find Column ["whatever name i typed inthe text box"].So first of all is this the correct way of going about what I want to achieve?If so how can I get it to work?BTW the next step for the user would be to double click the customer in the list box they are searching for to open the customer Details form for that customer, so I would need an ID or Index attached to that item to be able to open that record in another form.

In a program I am writing (in VB.NET, 2008), I have 2 classes, "Receipt" and "Group", each with similar properties, both implementing a custom interface entitled "IIDUser". In my program, I have a number of lists of "Receipt" and "Group", declared like:Friend receipts as List(Of Receipt)
I have written a few functions that apply equally to managing both lists of receipts and groups, declared like this one:Friend Function getNextAvailableUserLabel(ByRef theList As IList(Of IIDUser), ByVal startLabel As Short) As Short
Then called like this:getNextAvailableUserLabel(receipts, s)
I did all this in an attempt for interface-based polymorphism, as I thought writing 2 identical functions (except for that one would be for lists of receipts while the other for lists of groups) would be bad practice (and waste time). However, I get an "InvalidCastException" during runtime. It is explained, "Unable to cast object of type 'System.Collections.Generic.List`1[Receipt_Sorter_v2.Receipt]' to

I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
How do you carry out a query from a criteria e.g name entered by the user from a textbox. and then display the query results in a list box..

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
