I can do it via the webbrowser with getElementsByTagName but i just cant for the life of me work out how i split the returned html into either an indexed array or just use inStr or Split function to split this into seperate value, But if i have a csv file with 20 links i dont want to have to load every page into a webbrowser control just to use getElementsByTagName.
Now it all works fine and retrieves the source code from the page. I have only extracted part of the code which is relevant to the retrieving html to try to shorten this post.

I'm using WinPcap to capture incoming data. Basically I'm dealing with a continuous stream of incoming data, either as byte array or as memorystream (pieces up to 64kb).
I need to check this data to see if there's a certain url and then extract it.
The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?

How do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?

What am I doing wrong or do I use a incorrect way to extract text from an array? Using += takes up a lot of computing power when it reaches like 50000 characters so I want a method with much better performance

View 1 RepliesI have a question about how to get a button to check for a textbox contents, and then compare that with data in my fairly simple database (It's meant as a login procedure).
Here's my database:
It has 2 values, 1 for the manager and 1 for the Admin
Here's my Login screen:
Now...
Everything works just fine, all the code is correct so all the buttons work. For the program i'm making, there's 3 types of users, 1 user who can only change how much money a customer owes the company, 1 user that can add new customers and other little things and one Admin who can change pin numbers and manage backups and stuff like that. For the last 2, i need pin-number/password protection obviously.
The user should enter the pin and then press ok, after which the ok button checks if the pin number the user entered, corresponds to either identifier 1 or 2 (5566 or 6655 for now) and if correct, show the user the next form.
I need to extract specific data from a database. With starting point in this data, I will collect information on the internet. After the information is collected I need to check if this information is already stored in the database, and if not, then add it. This action is being repeated about 500-50000 times each time the procedure is being executed. (not often)
The approach I'm taking seemes sleazy and ineffecient and I was hoping you could point out some places where I might be able to optimize it. I've two open connections at the same time. The first I use to extract data, and it stays open throughout the whole session. The second connection is being used first to check if an entry already exist and if not, to add the data.
The reason I am using two connections is due to the fact that I got a reader bound to the first one, so it is rendered unavailable.
I was thinking that maybe checking if the data existed, and adding it if not, maybe could be contracted into one command execution instead of two. I don't know if it would be possible to do this with one connection only as well, as it seemes more proper.
I am trying to create a web-method to check whether a string contains a word which is in a list of 'not allowed' words. This list will be updated from time to time.

Something is wrong with this function. It verifies the first word of string. After that it doesn't return anything.

When people use if statements on booleans, they either do this
if booleanStatement = true then
if booleanStatement then
I know that they both accomplish the same thing, but is one better than the other? Outside of 'good programming etiquette'
