VS 2010 Get The Text Between Two Strings?
Sep 28, 2011
I guess my question has two parts:
1. My program has to read text out of a text file. I use some HTML tags to preserve the formatting. For example, I might have the line "this is a <b> line </b> of <b> text </b>" where "line" and "text" are bold. How do I make it so the string prints to a RichtextBox, but only "line" and "text" are bold? I would use a RichTextbox.SaveFile method, but the program works by reading a group of richtextboxes in a flowlayoutpanel and appending them to a single text file.
2. How would I extract the text from between two strings? For instance, I have created special tags for use in my program. These tags tell the program where to add controls. Say my string was:
"[IMG= "dog.jpg" /] this is a picture of a dog. [IMG= "cat.jpg"] this is a picture of a cat."
For each occurrence of the string "[IMG=", I would need it to find the corresponding "/]" and extract the text between the two. I could maybe do something with a substring function. I don't know.

Ok, so say the string is: <a href "[URL]">abc</a> And I just want to get the text "abc" from between the <a href "[URL]"> and the </a>. How would I do so? I dont think I can use the split function, can I?

First it might sound like an ordinary task but keep reading it isn't. I can't figure out how to find a phrase in a text file, and replace it with something else. Tried lots of things but always ending up with empty hands.
Suppose there's a text file in this order:
valueabc=6000.0000
valuettt=200.0000
valuexyz=7000.0000
I want to;
1) Find the phrase (e.g. valueabc) by scanning the whole text,
2) Replace the number that starts after "=" and ends before ".", namely "6000" in the middle with any number value i want.
I don't need the parts before "=" and after ".", only the number in the middle.

I am making a gradient colored text tool for a game I play where they use a 3 digit number as an RGB color code before text. Making gradients by hand is tedious, as to do a gradient you type one letter at a time with an RGB code that changes by 1 in front of each letter.
example: "^090H^190e^290l^390l^490o" Would be a color gradient for Hello
I have a user input text into a text box and choose up to 6 colors. The colors then are assigned RGB values, only instead of 0-255 they are 0-9. (So they look like this 000=black 999=white 090=green, etc.)
I have figured out how to do this, but now I need to place the RGB values in front of the users text while only changing one of the RGB numbers at a time.
So if the color values are 090 and 900:
"090 190 290 390 490 590 690 790 890 990 980 970 960 950 940 930 920 910 900" is what I would like generated with the users text spaced evenly between.
I have no idea as to how I would go about putting three digit color codes between the users text or how to change the color codes one number at a time. I could try to do this on my own but it would be sloppy and probably a lot more code than needed (I have a feeling I should be using a loop or something like 'for each')... It's been awhile since I opened VB!

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.

Is there an easy way to find a certain string within a string and then return the strings that you find as an array?I have written this:
Public Function FindStrings(ByVal strSourceString As String, ByVal strStartString As String, ByVal strEndString As String) As String()
Dim StringStartposition As Integer
Dim StringEndPosition As Integer
Dim Currentposition As Integer = 1

Here's the weird problem I am trying to solve but cannot get my mind around it. In a text box 1, the user enters 2 or more strings separated by comma. then in text box 2, the user enter 1 or more strings separated by comma. The output then puts the strings from text box 2 between the strings in text box 1
Example:
TextBox1 = visual basic, java, perl
TextBox2 = is better, compared to

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I have string which is:
document1.txtdocument2.txtdocument3.txt
What I would like to do is split it so it shows in a listbox as
document1.txt
document2.txt
document3.txt
I have come up with a solution which may work. Its preety over complicated too me but this is the only way I could think of?
What I need help on is a code so that after every ".txt" it will place a "/" so the string will look like this:
document1.txt/document2.txt/document3.txt/
Then I would use this code to split the string:
Dim I3() As String
I3 = I.Split("/")
For g = 0 To I3.Length - 1
ListBox1.Items.Add(I3(g))

how I can select the text in a textbox/richtextbox that is between two designated strings? Like, for instance, lets say "<b>" is the first string, and "</b>" is the second. The text entered in the textbox is "<b>hello world!</b>". How would I get it to programmatically select the "hello world"?
Also, I would like to know of a way to select the text between the two strings and the strings themselves, so that, inputting "Hello <b>world! I'm</b> awesome!", "<b>world! I'm</b>" would be selected.

I am looking for a control to load text strings into. I want to be able to use different font sizes and perhaps font styles for each text string. I also want to be able to select each text string. I am using a rich text box to obtain the formatting I need but I don't know how to set this up so that I can select each test string independantly. Alternatively I coulg put them into a DataGridView and get rid of the lines but this would look to structured as the cell width is contant for each cell in the DataGridView.

before you see any of this, you will have made a text file (dont ask how)
the text file will contain html with an unknown number of lines
(the user will click a button to add a new line to the file, so the number of lines depends on the user
each line will look like this:<a href="www.link.com"> text </a>[URL].. is just a place taker for what the user would have written there as well as "text"

I am reading a text file in which has three colums of information i.e.
00100 25690 21586
23510 25694 24856
25896 45478 52897
58745 59687 12364
I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.

Is there a way to use strings in Enums like the example below:
Enum myEnum
val1 = "some string 1"
val2 = "some string 2"
val3 = "some string etc"
End Enum
It seems like you can only use integers for the underlying values.

I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False
ToolStripStatusLabel1.Image = My.Resources.pic_Add_Warning
ToolStripStatusLabel1.ForeColor = Color.Red

I am trying to write login page code for the login button but can't find how to find a string in a .txt file. The only code I have managed to find on the subject is opening up the text file with the
FileOpen(1, "File location", OpenMode.Output) code, but even this would be best removed as it would open the text file containing all usernames and passwords within the file.I need the system to search for a specific string within a file ( Usernames___Passwords.txt (159bytes)Number of downloads: 134), and with that string find the password associated with it (in my attached example the letters/words after the apostrophe) but stopping at the end of the line.
