I want to search a string (which contains html source of webpage)and get all text that strinh holds, like:
TC83886783380753647814458
TC27072318654272127623234
...
so, i want to find all text that is located in code between "serviceid=" and "&" (example how it would look in html source/in string: serviceid=TC27072318654272127623234&)
so the result would be only text in that format (starting with TC and 23 numbers following it)
I think i could do it by parsing a string somehow
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:

I want to make a list of strings from the text of a search field. I want to make anything that is in double quotes be split out.
ex. sample' "string's are, more "text" making" 12.34,hello"pineapple sundays
Produces
sample'
string's are, more_ //underscore shown to display space
text
making
[Code]....
The format I need is a group of numbers in a text file and it looks like this and it will always look like this:xxxx x xxxxxxxx xxxxxxxxx x xxxxxxxxxxx xxxx x
The problem is that it can be anywhere in a text file so I cannot search by a particular line.
How can I search for this type of string format in a text file?
So I am trying to create a Win App to make copying files using Robocopy easier and eventually other tasks. Basically what I have so far is a Button that calls the Sub Robcopy_EXE. There is a tab on the form with 100 check boxes, one for each terminal, that will be designated by the user and a check box to determine if you want a detailed report or not from Robocopy. I also have a text box for the user to input the first 3 octets of the site IP Address. The check boxes and Input field are used to create string "Terminal_input" which is what runs Robocopy in CMD. Robocopy logs its progress to a text file that I have labeled "Status.txt". That is as far as I have gotten.

I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.
A huge bonus would be if it could count the number of occurrences inside the string!
I want to search for a string entered in a column of a datagridview in a text file.If this string exists in the file then allow the user to enter it otherwise dont allow the user to enter the string.Also,since I am reading data from the database into the datagridview, I have not added columns to the datagridview using edit columns option. How do I do this in vb.net.I tried doing something like this:

I am trying to use the Word Selection object to search for a text string and VB always crashes. I found a piece of code on the web but I cannot get it to work at all. I have many other apps written which work fine withsearching Word docs. The code is as follows:

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.
I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I want to take a string from a text box and split each letter of the string into an array. Then, I want to take the first item in the array(the first letter of the string)and capitalize it. Once I've done all that, I want to combine the array and convert it back to the original string it was, except I want the first letter to be capitalized(I've already placed this into a variable.)
Here's what I've come up with so far:

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

View 3 RepliesI have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time.

Private Sub displayOut(ByVal Channel As Object, Optional ByVal User As String = "", _

I have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.
