VS 2010 Searching A Listbox?
Jan 17, 2012
I have a listbox with multiple items:
Quote:
The Sopranos (Season 5) Boxset (DVD)
Braveheart (DVD)
MTV The City - Complete Second Season 2 (DVD)
I have a TextBox where a user enters a search:
The Sopranos Season 5 Since ListBox.FindString() wants a String and not a RegEx, I can't use a Regular Expression. (right?) So, if TextBox.Text = "The Sopranos Season 5", then ListBox.FindString(TextBox.Text) will not find my entry with "The Sopranos (Season 5) Boxset (DVD)".

I know the sort of a thread is already here, but I have a different question. I have ListBox1 and TextBox1 and the Items of ListBox1 are:California
Chicago Washington and as I start typing the text into the TextBox1 (TextBox1_TextChanged), then it will select the first Item in ListBox1,that is closest to the text in TextBox1:
For example:
If I type "A" to the TextBox1, it will select California (California)
If I type "C" to the TextBox1, it will select again California (California)
If I type "CH" to the TextBox1, it will select the Chicago (Chicago)
AND!!! If I type "SH" to the TextBox1, it will select the Washington (Washington)
so it won't only search the first letters, but it will even search the letters in the middle of the text, too.

Right now im using
If ListBox1.FindStringExact(TextBox2.Text) = "0" Then
Label2.Text = "yes"
GoTo procheck
[Code]....
and it searches the first item in the listbox correctly but nothing else. Im assuming im going to need to loop through the listbox somehow?

I will include a link to a copy of my source Code. The Problem is that I have to create a user management system. I have almost all my features working but there are one or two I can't get working. When the program loads a text file is read and the program lists the first name of everyone in the text file into a list box. I want to be able to get so that when you click a name in the list box, the persons information will be displayed in the text boxes to the left. And also when you edit those text boxes you can click the button for modify current and it will modify that persons data. The other problem I'm having is being able to search that text file for the users e-mail and return the first names of people who have that e-mail into the listbox.

I have a code to search for specified text in all listbox items. Here it is:
ListBox2.Items.Clear()
For Each item In ListBox1.Items
If item.ToString.Contains(TextBoxDropDown1.Text) Then
[code]....
This works fine. But if I have search for this:
"My Search"
I wont find this:

Is there any way to search for text of any casing, and if so how can I adapt my code to do this.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.
Public Class Form1
Dim colors() As String = IO.File.ReadAllLines("colors.txt")
Dim IsCrayolaAnswer As Boolean = IsCrayola(colors)

I want to search for a specific string within a text file, however instead of hard coding these string values into the system is there any way I can have them within an external file such as a text file and have these values that are to be searched in there and then pull them from there?

I've been trying to figure this out lately by looping a richtextboxfinds code replacing the integer with a value -1 than the integer before it after the starting string in that code. But for some reason I can't get it to loop through my text upwards.
It loops down through the text fine, however i'm not satisfied with that loop either, it seems a bit buggy.
[Code]...
The down search seems to take 2 clicks on my button handler to actually change the selected text that it finds, and then I used the code for an upward search, it would search one more down upon pressing my "search up" button, before not doing anything after that on the next click. So i'd assume something is wrong with the down search function as well.

I am trying to search and XML file for a variable on a specific node. Following a tut I can setup a search for the node correctly and it returns its name - but it doesn't find any values for any children of that node.

ListBox1.Items.Add(dv(index)("Skill_Name").ToString() & " " & dv(index)("Faster_2").ToString())

I need to search a keyword put in a text box. In my case, I want to search records by the month name. I would want a command button that displays results according to the keyword typed in a text box. Now I tried two methods, one with a text box, one with a query. Both Do search, but the fields return empty.
Heres the code for my form where the datagrid is:
vb.net
Public Class Form6
Private Sub Pay_CalculatorBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Pay_CalculatorBindingNavigatorSaveItem.Click
Me.Validate()

I am coding on Visual Basic 2010 and need some My Access database table has following information:
FirstName
LastName
PhoneNumber
Basically what I am trying to do is create a Search function where the user will enter a First and Last Name in the search boxes and upon hitting the ''Search'' button the program will look through the database and check if the records exists.
If the record does exist then I want the Phone number to appear in a separate textbox which is named txtPhoneN. I have included the code I use to connect to the Database. I have already managed code the part to Add new record to the database.

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True

I'm trying to implement a way for users to specify which files they want to backup by typing in file extension into a listbox.But I'm a but iffy on how exactly to do this.
This is what I have so far:
Dim n as integer Dim extensions(n) as string for each fe as string in listbox1.items
Here I want to add *.txt or *.docx from the listbox as a string in the array above whilst incrementing n by 1 for each new string next How exactly do I do this?

I have 2 Access databases;
Db 1 & Db 2, On the form is a list box which is data bound to DB1 'MainName', and a bunch of textboxs which populate from the record selected from db1 in the listbox.
In DB1 the 1st column is called 'MainName' and in DB2 the 1st column is also called 'MainName'
Now what im looking at is when the item in the listbox is changed, the record in the second database which has the same String in the 'MainName' column is also selected.
The route to take that i can see is having both databases added to the project , and have the listbox apply a filter on database 2 based on the selected item.
(im using 2 separate databases as when my project updates the DB1 also updates, but DB2 contains the users own strings so i don't want that to update as it would lose all there saved strings.I dont know much about lookup tables etc but they must all be in the same database right? so that rules them out, due to the update issue.)
