VS 2010 Searching Up Through Richtextbox (not Down)?
May 27, 2011
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 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)".

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 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 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.
I get this error:

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.

I have a program that appends text to a richtextbox.I do it like this :RichTextBox1.AppendText("[" & Now.ToLongTimeString & "] <" & Username & "> : Hello World !" & vbNewLine)
I know the username.Now, I searched google to color the username (the text between '<' & '>').It works, for the first line at least.As soon as I add another line, only the first line stays colored.How would I do that so it colors every line?

I've developed a MySQL chat app that I have in my program. It works perfectly, however all of the text is the same color. I use a silver-on-black scheme. I'd like to do 1 of 2 things, whichever one is.. er.. "more possible". The first option would be simple - alternate each row's back color. So that one row would be silver-on-black, the next row would be black-on-silver, and so on alternating. Each row is separated by a "vbCrLf". The second option would be to merely bold or turn to white the info text. Here's the format of the chat messages: [{time} - {user}] {message}. I would want [{time} - {user}] to be bold and white. Are either of those 2 options possible? Well, I know they're possible

When setting the selection of a RichTextBox, the selected text is highlighted even though I set the HideSelection property to True. Once the RTB loses focus then the selected text is no longer highlighted. Programatically setting the focus to another control doesn't hide the selection, only physically clicking another control will hide it. So is there a way I can make the RTB not show the selection right from the start?

I'm trying to make a way for them to export orders to a .rtf file. In order to preserve formatting (bold, underline, etc.), I'm creating a RichTextBox (through code) and formatting the text appropriately. To save the output, I'm simply using the RichTextBox.SaveFile method. Now, to list all of the products that were sold in the order, I'm deriving the information from a ListView. The ListView contains the product name, product price, and quantity sold of that product. I cannot find a way to list the output in a table-like structure, so I tried making a DataGridView and pasting it onto the RichTextBox. Unfortunately, this didn't work at all, so I was wondering if anyone had any ideas as to what I can do. I can't simply use Tabs to space out the information because it doesn't get formatted nicely.

I've decided to come back to working on an old program of mine, and it's been coming along nicely, but there's this one thing that I can't get working.I have formatting options (Bold, Underline, Italics, Strikethrough) available on my program, and they all work properly. I'm giving users the ability to export all of their text from a single page on the program to a .rtf file. However, the problem I'm experiencing is that each page has numerous RichTextBoxes on it, so I cannot simply use a RichTextBox1.SaveFile() command or something similar. I want to compile all of the text (including formatting) from all of the RichTextBoxes and put it on a single .rtf file. Currently, I'm getting the text from the RichTextBoxes using the RichTextBox1.Text command; unfortunately, that only gives me plain text without formatting. So, what I'm wondering is: how can I get the formatted text from a RichTextBox? Is there any command?
