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 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:
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.
Now it is really hard to find manually all those statement which starts with "copy ".I would like to create another new text file with all those statements which starts with "Copy".
Im trying to get certain text from a webpage and display it in a textbox. In the image below , i want to disply all the text after "Filename:" in a textbox as highlighted below.
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:
Sun20 Off 0330 0329
[Code]....
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.
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'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 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.
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.
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.
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.
1. allow the user to specify a folder in which to find a specific text files,
2. to read a few specific numbers within each of those few text files, (eg. in txt file A, #A = '1', in txt file B, #B = '2', etc)
3. place those numbers into multiple comboboxes, (eg '1' into CB1, '2' into CB2, etc)
4. allow the user to change the number from the combobox drop down list, (eg CB1 change to '2', CB2 change to '1', etc)
5. Click to overwrite the old numbers in the text file with the new numbers and save the text files
My main problem is no. 2, how do I read a specific string in the text file and display it in the combobox?(Win XP, MS Visual Basic 2008 Express Edition with sp1)
I'm trying to extract the text fields inbetween the code but the text is always changing so I'm not sure how to keep this dynamic. In put them in to the proper text boxes.
So text box 1 might be Date: then it pulls the date.
and there are multiple listings. so I need it to loop until the end of </table>
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.
[code]The two parts I've coloured red change, I need to grab the first part which is the link but I'm not sure how to do this. I've used regex before and it doesn't look possible to use it on this on this, there's about 25 of these in the source.
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 have been working lately on a program who extracts URl Source codes!The program does work with most of URL but not for MEdiafire URL!When i check the source code from the web browser i can see there is some code missing;y tried diferrent types of Encoding.

I'm brand new to visual basic and I've been given an exercise to extract data from a text file. I can get the lines of data to read in and can get the names out using the following code. How can I extract the department i.e. sales and finance also using the mid and instr functions? I also need to be able to list list the people by department using a dropdown combo box.
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.
Need a bit of help with HTML Agility Pack!Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.
Dim htmldoc As HtmlDocument = New HtmlDocument htmldoc.LoadHtml(html) Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")
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".
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 am trying to test bit 7 (87654321) in the byte DB2 to check if its true. The below code does not seem to be working:
If DB2 And &H40 = &H40 Then Label1.Visible = True If DB2 And &H40 = &H0 Then Label1.Visible = False TextBox6.Text = Hex(DB2 and &h40)
I do see the value of DB2 changing from &h00 to &h40 in the textbox, but when evaluating in the two if statements, it never evaluates to true (for testing, the only possible values for DB2 right now are &h00 and &h40)
I have two collections that I am comparing to a thrid collection. Both collections have 147 values in them. I am wondering how I get the results of the comparisons in a text document concatinated to look like this:
Output from Collection A Comparison Collection B results
Repeat the above two line until all results have been written to the text file. Currently the program runs and the document is not created. Here is the code:
Dim sb As New System.Text.StringBuilder Dim ordersCount As Integer = &H3E8 Dim i As Integer
