VS 2010 Extracting Text From <label> Tag?
Oct 29, 2010
I'm trying to extract the text between: <label for=field_1> and </label> I have captured the HTML into a string using the webbrowser control, and am using the following function to try and get the text within the tag:Public Function midReturn(ByVal first As String, ByVal last As String, ByVal total As String) As String
[Code]...
However, this code will not work, if I use <label for=field_1> as the first string and </label> as the second.

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.

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,

I'm trying to implement Bandwidth Total calculation into my little desktop monitoring program using 2 *.txt files. Everything else is working great except for the writing/reading part of it. I had put this together originally without the intention of bandwidth monitoring, but I've decided it would be a good thing to have.I want to have 2 monitoring types: Windows Session Bandwidth Total & All-Time Bandwidth Total (since the program was 1st run on the machine). The counter is on a Timer (2nd of 2), and I want it to write and add the label values each second into the file, then when Form3 is opened, to read the text file and show the results.

I'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?

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?

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I am trying to extract text from an htm file (output.htm) to write into an SQL database.
I used "pdftotxt" to re-write the original pdf document into an htm file, in 'raw' format, and end up with lines like this:

Off
0330
0329

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.
It seems like a huge task that is way beyond my limited capabilities, so I would be very grateful for some sample code in VBasic.

I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.

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.
Example snippet from text file:
>Date 5.3: Tech Manual {30201}
Freya Plumes (30201) - 1
mu
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.

I am trying to extract text from a .pptx file. I am able to extract from all other shapes except a shape that is identified as a msoPicture to right click on this shape in powerpoint and ungroup it, but when I try to do this from code it tell me that the ungroup method only applied to group shapes.I did some research and found out that the msopicture shape comes from a .emf file but I don't have the least idea how to ungroup this shape or get the text from it through code.NB: When I right click on the shape in powerpoint and select ungroup a message box pops up saying "This is an imported picture, not a group. Do you want to convert it to a Microsoft Office drawing object?". But I cannot seem to find a way in code to convert this shape to Ms Office drawing object.
