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?
I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places. Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed. If they are not both in the table a suitable message is displayed
Dim town(1 To 5) As String
Dim Dist(1 To 5, 1 To 5) As Integer
Dim First As Integer

I think the best way forward is pass a parameter to the function findnumber.
I have an array of filenames, and an array of files in a directory. I use a for loop in a for loop to check if those files are in that directory. Look at the below code to illustrate my problem. [code]
I am teaching myself VB with the use of a basics book, but I can't seem to find help for my project in the book.I am working on a project in which I have to open data from a csv file and use it to make graphs and analysis. The data is displayed in such a manner:
row 1: column titles row 2: units row 3-100: data
what I want to do is create arrays for each column in the csv, populated with the data.
I was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:
Does anyone know of a way that you can get the string that is held at this reference point (its the contents of a registry value that corresponds to a string - see this thread for more info [URL]

I think I've seen C# (or maybe C++) code use lines like this but I cant find any way of getting the value from the DLL in VB.NET
I have some code that is extracting tracked changes from a document. The trouble is its very slow, taking around 60 seconds to capture each tracked change. I originally thought that pagination was slowing down the code (its quite a large word document). However I have turned that off but its made no difference to the speed of the function.
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:
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.

Many types of credit cards have the same format. This format is XXXX-XXXX-XXXX-XXXX, where X is a digit.The dashes are embedded into the string containing the card number.Create a console application to * Declare String variables Partl, Part2, Part3, Part4, and InputString. * Read a credit number consisting of 16 digits only, no hyphens, into InputString.* Write the statement(s) to extract each four-digit segment into Partl, Part2, Part3, and Part4* Display the four parts.This is what I have, and I cannot figure out what I'm doing wrong because there is an error when it runs.

what is the command line to single out certain parts of text from a string only..for example string = "Hellodullardtomboy".what is the command to capture only the word "DULL" between "hello" and "ardtomboy" only.
I am trying to extract numbers from string text. e.g. 1 day (8 hours)' I need the one and the eight integers pulled out I would like to extract then store each number separately for use later. I am aware of techniques to count string text, but not pulling certain information from it.
lets say webpage has 2 strings named sampleObj="sample1" and sampleObj="sample2" Even though sampleObj remains the same the text inside, however, changes.How would you loop inside page and get sampleObj text each time? I tried Regular Expressions and GetElementsByTagName but no luck.
basically i have heap loads of text in a sting.I want to be able to extract text between two point in my string.So say for example want to be able to extract the text between the two brackets.

However a coworker and I are wanting to build a separate program instead of just running simple scripts.I'm running into the following problem:I am not sure how to program visual studio 2010 to the extent that when we paste in predictable text structures that it will take only certain items out of the text, assign them to variables that we can call later.Example:We log into a lot of UBRs for testing and the structure is basically thus:
I 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.
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: Entire Program Code: Imports System.Text.RegularExpressions Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load [Code] .....
I have tried almost everything I could do, I am relatively new to string functions so that is my main problem.
I have a text file I'm trying to pull specific data from to make a report in excel and am wanting to know if my code can be improved or if I have something wrong. If it's apparent to anyone that I should be doing something elThis code does work but, very slow. These reports take up to 20 minutes for about 100 files so I am wanting to decrease the time somehow. I have attached the whole sub in a text file, it's about 900 lines long so don't think I should post all of it. This is one part that seems to take the longest:Partial code that reads the text into a string, then each line is read to find whether it holds the data or not. Inside this while loop, I am checking numerous lines to see what they hold and extract specific items. First I verify it's a interface by checking for "line protocol".
Dim str As StreamReader = File.OpenText(filefound) While (str.Peek <> -1) If txtLine.Contains("line protocol") = True Then 'Found an interface,

For example, if I have one array with the values:[bt1, bt2, bt3, bt4, bt5....] witch is the name of each control.Is possible someting similar this? :
'array Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces 'Need to output names 'adapter.Name' to another array for faster access. 'Iteration, slower
