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 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:

Basically 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've been having problems extracting the value of a Regex in a String. I have a string with several regex expressions and I need to get the value of each expression's match. The thing is though, it's not returning the last match correctly. For example:
Regex Pattern: I play (S+.*?) and (S+.*?)
String: I play the guitar and the bass The program is returning the value of the first expression as "the guitar" but it's returning the value of the second expression as "the" instead of "the bass".
I have a string that looks like this:
var expression = @"Args("token1") + Args("token2")";
I want to retrieve a collection of strings that are enclosed in Args("") in the expression.
How would I do this in C# or VB.NET?

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?
