Extracting Text From Htm File?
Aug 21, 2009
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.

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 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 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?

But I cant think of a way to do it, the only thing I can think is to try and grab the text on the line after each "+CMGR:"

I have one text file with few thousand lines of information. Out of few thousand lines, few hundred lines are something like:
Copy "\server1C$abc.msi" C:windowsinstaller1abc.msi
Copy "D: empxyz.msi" c:windowsinstallermissing.msi
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".

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.

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.

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,
