View 7 RepliesBasically this is my problem, showing the results of a string. I am making a program for a customer and he wants to be able to extract a string or set of emails from a large group of text. In this case he wants to be able to copy a webpage and extract all the emails out of the webpage. The problem i am having is showing the results of the List(of string) Function. So far, I can copy the page, paste the content to a textbox and then i have a function that is supposed to filter out the emails and paste or Show them in a list box.
I dont know why but no matter what I do I always get this error:
Error1Value of type 'System.Collections.Generic.List(Of String)' cannot be converted to 'String'.
This happens when I try to output the return results to a textbox or list box.
Here is the code for the whole program:

I'm trying to create a small program, which I think will be helpful to others(in here). My aim is to convert the English text shown in screen to Malayalam. English-to-Malayalam conversion is not a problem. But the problem is, how to extract the text from the screen. In most of the converter/translator, the text needs to be copied or written down in the translator tool. But my program will cut off that part. That is, simply move the program window (having a rectangle hollow portion) to the English word that needs to be converted. And upon pressing a button (or autodetect), the English word is converted to Malayalam.
So, my question is how to extract the English text(or words) from the screen (which is seen through the hollow portion of the window.
Here's a screenshot of what I'm trying to do.

My program uses the serial port to receive characters as a string, then it should extract the integers from this string. This seems fairly simple, but so far has been a very tedious job.
My string is called txt. The problem is that there's no telling how many characters / integers txt will hold at any given moment. For instance, it may equal "4" or "4 5 6 7" or "P 0 1 2 3 4 5 6...255" - with spaces included. I need to reference every number within this string to use as data. I've tried the following:
dim c as new char
dim n as new integer
dim i = 1

This is my second post on this topic. I included all the code this time. In calculate click event the value is zero and I don't understand where I went wrong. My work is due tomorrow, if anyone can tell me why I can not extract the price from the string. What this program is doing is taking items from the stockListBox and adding them to the shoppingList Box then extracting the price from the shoppingListBox and adding the prices together.t a note- in public class I changed the string and seperated the price from the item, not sure if I was suppose to do that.lso, everything works except the calculate event.

I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

I m trying to write a program that is mostly dynamic. This program enables the user to read in several inputs (temperature, pressure .) and perform calculations on those inputs. After that the program sends an integer to an analogue output port. The program automatically determines the number and type of the inputs. It also creates something called a variable handle for each input.This is then saved to an array input_handler(0,x). That array is sized this way input_handler(0 to 1 , 0 to 9)
0= handle (integer)
1= value (integer)
The program dynamically creates a button for every input. There also is a button for every mathematical operator. This way the user can create a function by pressing buttons.This function will be saved to a string. That string will look something like this input_handler(1,0)+ input_handler(1,4)/ input_handler(1,3)Well now Im stuck with a string and VB will obviously just print out that string instead of calculating anything. Is there any conversion I can perform so that string becomes the actual array values?

View 10 RepliesI am using an API (WSUS) that will give me an XML fragment that I need to work with. Essentially, I need to go through the fragment element by element, identify what type of element it is, and then put that element into the datagridview. The goal is to have a column with a human readable interpretation of the element, plus that actual element itself in a hidden column for further processing. So, using the below XML, I want the DGV to have column that says "Begin Or Group" and a hidden column with "<lar:Or>".
I can get an xmltextreader to loop through the elements just fine, but I can't figure out a way to return just the current element in XML. I've tried ReadString, Value, ToString, and a bunch of other stuff but just cannot seem to figure it out.
Here's an example fragment:

I realize this may be a simple request, but I am fairly new to VB so even the simplest tasks are sometimes over my head. Basically, what I need is a function that will take a URL from one of the text boxes on my form, and extract a certain piece of text from that URL. The problem, for me, lies in the fact that the text in question isn't always in the same position, character wise, every time. Basically, the URL looks something like this:
url...randomNumbers rarely seems to be the same amount of characters each time, however the randomNumbersINeed always appear after the second underscore and end right before the third underscore, no matter the amount of randonNumbers that appears before hand.The process I am working on does the following:
1. Takes the raw URL that I have pasted into a text box on the form.
2. Declares that text as a string.
3. Extracts randomNumbersINeed from that string
4. Assigns or declares randomNumbersINeed as a string
5. Appends that string to a .txt file.
I can do steps 1, 2, 4, and 5 with no problem, in fact I've already got those set up in my code ready to go. I just need a function that could extract the numbers from the URL.Could someone help me out here or point me in the right direction?

What I am trying to do, using the above example, is to look for anywhere in the list where a date(e.g Mon24) is followed by lines containing KL ####, and to extract the date and the KL #### for writting to a database.

I'm trying to identify a specific string within a text file, and then extra a couple of bits of information that follow from that.

These are made from brightly coloured. I want to be able to find where it says "Tech Manual", and then assign "Freya Plumes", "30201" and "1" to variables for manipulating and exporting to another file. There will be many instances from the same text file with similar information, so I'd need the extracted strings popped into an array for later referencing.
