VS 2010 - Searching ListBox Using TextBox?
Apr 1, 2011
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.

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)".

Quite simple but I'm having the hardest times trying to write something that'll do what I want. I have 1 listbox with 3 pre-defined strings each in their own index. I'm trying to search through a textbox to see if any of the strings in my listbox were found. So far I have no compatible code so I seek help from the professionals.

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.

This works fine. But if I have search for this:

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

i am working in a project and what i want to do is to have a search drop down list and text box. Lets say i have a gridview with all my results from database. In gridview i can see Name, Surname, country, phone number. From the drop down list i want to select the column in which i want to make my search. For example, from 3 choices(name, surname or country) i will select country. Then i have to type a country name in text box and the search engine will make the search for the country column. For example if i will type "U.K" in text box as a result i want all the people(name,surname,country) WHERE COUNTRY = U.K.

The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.
The highlighted part of my code is the text closed in quotation marks.
"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True
End If
This code is under my dgv cell click event. Here is a screenshot for the column header where I found the error. [URL]

im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox
textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text
For Each item As Object In listarrays.Items
If item.ToString = Me.TextBox1.Text Then
[code].....
use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?

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'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 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:

Public Class Form6
Private Sub Pay_CalculatorBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Pay_CalculatorBindingNavigatorSaveItem.Click

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.
