How on specific behaviour can be created in a custom class. I want to be able to create a custom class (a kind of list) where I can access the items by their index (this is the easy part), but also by a string that would describe them. Here is an example:
MyClass(1).SomeProperty = "NewValue"
MyClass("Item1").SomeProperty = "NewValue"
You can see this kind of behaviour in dataset for example where you can select a table by its name or by its index like this :
DataSet.Tables("MyTable").Rows...
DataSet.Tables(1).Rows...
How can I create a custom class that will behave like this?

I've tried many things in the past, but with no succses.
I have a list of File_Name, File_Date.
I need to check this list sometimes against a file name and sometimes against both a filename and a file date.
I've been doing a for each loop and checking each value, I've tried a hash table keyed on file_name which is much faster, however I also need to check to see if the file_name and File_Date combination exist.
Is it possible to have a list that I can do a quick search on using either the filename or both the filename and filedate.

I have been trying to figure out how to get my code to work. (It was a homework assignment which has already been turned in but I am determined to get this code to work.)I have a text box titled txtSearch and btnClick.I need to search a list box for a city name and then have it displayed in a message box. If there is not a match then I need to display an alternative message box stating there is no match. City is in the list box starting at 16.The text needs to be case insensitive.I am only getting the message "That is not a valid city." for any entry that I type into my txtSearch even though I know it should be a match.
Here is what I have for code
Private Sub btnFind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click
' Declare variables to find text on txtSearch when button clicked
Dim length As Integer = txtSearch.TextLength
Dim value As String = txtSearch.Text.ToUpper

View 1 RepliesI think my question is a little more complicated than I can fit in the title. Say I have a data class for contacts:
Public Class Contact
Public Property Name As String
Public Property Phone As String
[Code].....
I have a List(Of Contact) object with several different contacts. How would I search the List for the contents of one of the properties and return the resulting Contact object?
Following is the format of the data stored in my arraylist.
A-Amsterdam
B- Brussels
C-Canada
so and so forth. I wan to search my array list by passing just the first few characters till '-' So if i have something like AA-Test then i want to pass just 'AA' to check if it exists or not.
I know that i can use contains or binarysearch but it does not serve my purpose as they both compare objects.
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...

(I basically got this online and not even sure its the correct usage.

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.
