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
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?

This illustrates a series of bytes that I've received from a socket and assigned into a byte array (frameData). How do I extract the ascii string from frameData if FrameData.Length is 79 bytes long and I need to extract the byte locations whose begin -frameData(26) and end frameData(44) are given by the arrows I've drawn?

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
I have been puzzling over this for about 2 days now but to no avail.All i am trying to do is retrieve all the "<a href = "myLink.php">MyLink</a>"
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.

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.

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
View 7 Replies[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
