Is there any function similar to string range in vb.net 2.0? What I am try to achieve here is to extract some text from a string with unknown length. eg. given string = text text text mytext1 text text text text mytext2 text text text text expected string = mytext1 text text text text mytext2 So I have the indexes for "mytext1" and "mytext2". I am looking for a way to get the text that wrapped in between those two strings or indexes.

View 1 RepliesI 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.

View 1 RepliesI have a string which I have pulled out of a text file as shown below,[code]and I would like to split it up and get the numbers into individual string() arrays.

View 3 RepliesI'm working on a way to authenticate users in my app, and what I've come up with is the following method.To write to a database, the user must have an account in SQL server 2008. However, I still want people to be able to view the application if they don't have access, but only read, they can't sync any changes. This is working well, as I have a string array hard coded containing approved users:
Dim Users() As String = {"BWANG", "EDASALLA", "ERICHARDSON", "HALONZO", "JCHAPMAN", "SKIM", "PMACK"}
The one problem with hardcoding is that if I need to ever add a user later on, I'd have to release an update to the program. (which isn't hard as I already have updating built into the app, and users can still download updates even if they can't sync.)
What I'd like to do, is use an encrypted .dat file that contains the user names, and store that with the application, so that i could always be added to, and only one file would need to be downloaded.
I have code in place to encrpt and decrypt the .dat file (called users.dat) and this code works for single text entries in the file. I need to figure out how to load a list however into the array in place.
Imports System
Imports System.IO
Dim userfile as String = "C:users.dat"
Dim Users() As String = Data.Decrypt(File.ReadAllLines(path))
Basically each line in the file will have an encrypted user name, and i want it to decrypt each line and store it back into that authorized user list.

I have a feeling it is an easy one, but for the life of me i cant figure it out. My project at the moment is to grab content from a website and use it in some way (havent worked out this part yet, still trying to get the data).
Currently, i have grabbed the whole website and written it to a text file.. No dramas there. Then i read each line until i find a certain string... Again, no dramas. MY problem is; after reading and finding the certain string, i want the program to grab whatever "characters" there are until it reads a certain string again, and then put those characters into a string for later use.
so for example:
READ WEBSITE...
CREATE TXT FILE...

Ive figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

I have a text file (CSV) approx 100k lines (8Mb). I want to search the entire file for a particular string eg, "apple" and for all lines containing the string to be printed in a text box. have successfully done this using streamReader to parse the CSV and check each element against the search word eg. apple. This has proven to be very very slow and I have read that the "ReadAllLines" method is much faster.
View 8 RepliesI have two text boxes on my form. Textbox1 and Textbox2. Textbox1 will contain information. I want to code my button to read textbox 1 and put it into a string or some way for the app to read the textbox and store the information into it's memory.Then I want to be able to read that string into the second part of my application.
a). read the textbox into a string using a streamreader and then use a streamwriter to write the data into a string?
b). save the textbox to a .txt file then use the openfiledialog to read the text file into a string to use?
