I have been practicing making small programs in a feeble attempt to learn something, but have hit a brick wall. I can not find out how to accomplish the seemingly simple task of searching a list box(containing names of music files) based off the parameters entered in a text box.

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 have a MyList (List Of Longs) in which I need the check a specific relation between any two members of that list, if the relation-check returns true I need to delete checked member.I was used to do something like that with 2 For Next Loops, is there a better way. Would it even work that way with Lists?What is happening when an Item is removed from the List that has not been called by the outer For-Next yet? [code]

View 1 RepliesHow can I search for files and list them in a listbox? And how can I search for only ex. jpg or png's?
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.
What I am trying to do is search through a list of file names looking for files with the same File name the following code is run from a button on the form The code seem to work ok up to the Array the line marked with ### is the line that the code stops at run time.

So I have an excel app with a drop down list and it contains many values. Is there a way I can just search through that drop down list in vb.net? I can't seem to find where these values that populate the drop down list even come from So I thought just searching through it is easier?

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

I 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 know I would put this code in the keypress event of my test box, but just until I get it working I attached it to a button to search. (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.
I've taken a few vb courses a few years ago but I've been wanting to write a script that will search my harddrive(C:) for any ".dda" extention and list the location to a listbox.
