VB: Searching For Text Within All PDF Files And Returning Results Of PDF Files Where Text Are Found On
Jun 20, 2011
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

I have been taking a class in Visual Basic and am currently working on my final project which I am having some trouble with. I am using Visual Basic 2010 express The project is to create an application that will store data in a text file, specifically, Last Name, First Name, Customer Number, Address, City, State, ZIP Code, Telephone Number, Account Balance, and Date of Last Payment. I have gotten everything done except the ability to search the file by Last Name or Customer Number. I have no idea how to go about this? I was thinking of ways to use indexof or Readline to be able to search the data, but I'm not familiar enough with the code to come up with a good solution. Below is a picture of how my form looks..As you can see, I'm currently using 2 separate forms to get the data from the user. Here is the code for Form1 which is the "Customer Accounts" form in the picture.
Imports System.IO
Public Class Form1
Public customerFile As StreamWriter ' Object variable
Public customerFile1 As StreamReader ' Object variable
Public strFile As String
[Code]...
There isn't enough room to post the code for my secondary form, but you get the idea. I would like to be able to enter a search term in the textbox on the bottom right of the form, and either search the data as its displayed in the listbox, or search the actual file? I was thinking that the results would be displayed in a messagebox?

I need to scan all files on our solution (aspx, js, ascx, etc). Our solution contains 22 projects all in all. What I need to accomplish is to search for all files which contains "img=" in its content (not filename containing "img") I don't want to do this manually of course (opening and checking files one by one). How I can do this faster.

I'm trying to create a folder search operation. The folder will have several text files (.txt), and user will specify the folder path and a search string, and the program will search the exact string within the text files which are located in the specified folder, and show the files. So far I've done nothing. I don't know how I can do folder operations with vb.net. a link to reading material.

Simply put, I have a text file full of reg values. I want to search the text file for X number of reg values. I want to then, have those values and their dword values (whole line + next 3 to 4 lines in the file) listed in either another text file or an Excel spreadsheet. Regardless of the format, I would like to have the values sectioned off for each of the values searched (probably tables of some sort).[code]...

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata
[CODE]...
Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.

I have a problem which I have tried to solve in several ways, and by searching the Internet for various terms, searching through books and Visual Basic instructional videos, but none have yielded the correct results. My goal is as follows:
1. Create a Database listing job names, job numbers, and a link to the file about the job.
2. Create a form with 2 text boxes, a search button, a box to display results, and a preview panel.
The two above steps have been completed. The following is where I get stuck
3. I want to search for either the job name, and/or the job number, have VB search through the database and return the results in the results box.
4. On clicking on one of the results in the result box, the preview panel will show a preview of the file.
Notes:
i) The files being linked top are Microsoft Excel files.
ii) The box I have used for the results currently is a listbox, though I've no idea if this is the correct choice for what I want to do.
iii) The database I created is an *.xml database created in Visual Basic. I am a fair beginner to VB, learning as I go, but I'm stumped as to how to achieve this so any pointers on how to achieve points 3 or 4

My app is a Bible Reader. At load up I can choose Genesis Ch1 and its entirety pops into a rtb. I enter a word to search for like 'God' and hit the SEARCH button. The results I get are initially what I want. I get the verse 1:1 In the beginning God created the heaven and the earth. But then the app replaces the script with other words containing God, but all jumbled up. Here is the code I am using: Private Sub ToolStripButton2Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton2Search.Click Dim stSearch As String stSearch = Me.ToolStripButton2Search.Text For Each Line As String In File.ReadAllLines(Path.Combine(Application.StartupPath, "Bible VersionsKJV 1611King James Version of the Holy Bible.txt")) If Line.Contains(Me.ToolStripTextBox1.Text) Then Me.RichTextBoxViewer.Text = (Line) End If Next LineBryn Ryver

i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like
Dim strTest As String
strTest = File.ReadAllText("ae.txt")
Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.

I'm doing a project where we are re-creating a very old system.The client wants the same base functionality and some improvements.One of the things I'm currently working on is the note-system. These are used as flags of some sort, but are also used as a comment field for some products or client profiles.In the old system you could write the text and save it like you would get in a .txt file. They want the new one to be able to do word formatting such as:
Different font sizes (Only some parts of the text)
Different font colours (Only some parts of the text)
Underlining of words
Bolding
Italics
Tab-spaces
Those are the specs they want. What I need to know is the following:
1) How do I do that?
2) Currently they store all these files on the server as text files and the database have paths that refers to each file. I want to be able to save a text file with that formatting to the HDD of the server like in the old system.
3) If possible I would like to save that text to the database with the formatting.

With regard to RichText, obviously information is contained somehow with regard to the text colour, font, size as so on and as it supports more than the ASCII character set such as Unicode characters and so on.
Now I know that Microsoft Word .doc and .docx files contain such information.
My question: How to extract just the rich text information only and ignore all the formatting
information such as bold, underline, italic and so on. How can this be achieved with VB.Net
What I am thinking of here, is, imagine a CSV ( comma separated value ) file but in Rich Text Format.
In relation to this, does Notepad only support a limited character set, i.e. ASCII only?

I am building a vb.net application with VS2010. The aim of the application is to change sln. files from VS2005/2008 versions into VS2010.I am using a Form with 2 text boxes and 2 buttons. When I click the 1st button it reveals the sln file in the text box. Then i have a 'convert' button that I want to use to 'convert' the file that appears in the first text box. I have come quite far with the source code but am just a bit puzzled as to how i can retrieve the VS2005 sln files and to get the 'convert' button to display the text in the 2nd text box.[code]

I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location

I'm trying to make a small database out of text boxes and text files, something where sql would be overkill, not to mention beyond my experience. I want to be able to write the contents of the text boxes to a file.txt (the easy part) then being able to retrieve them back out into individual text boxes. How would I pull this one off?

I'm fairly new to VB.NET, and I'm working on a text editor with a tabbed interface. I deal with large text files. Should I have each tab / text document open up in a new thread or a process? I basically want the entire application to always run fast as the text editor is just one part of it. If I have several large text files open I don't want the rest of the application slowing down a bit.

I can search all the images with .jpg extension and pass it to the fancybox gallery , The issue is i just want the images of particular productid for instance if a product has 5 images , and they are saved as (productid_imagenumber.jpg) , therefore a product with productid 99 will be saved as 99_1.jpg , 99_2.jpg similarly 99_5.jpg,I can pass the productID but i cant find a away just to get the images of that productID , instead of getting all the images which is done by the function below:
Dim directory As DirectoryInfo = New System.IO.DirectoryInfo("C:Images")
Dim allImages() = directory.GetFiles("*.jpg", SearchOption.AllDirectories)
Dim strContent As String = ""
For Each image As FileInfo In allImages

I'm creating an app that has check boxes that will define a search. The files all reside in one folder. I've looked at some tutorials that use io.directory.getfiles and I can get this to work. But what I think i want to use is: io.path.getfilename because I don't need the path (though I'm about ready to make an exception).
When should I use io.path.getfilename and can I use that method to do a search? I can't figure that out. I would think it would react as io.directory does but I am incorrect.....
Here is the code. Its short becasue I'm just figuring things out first:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim afiles() As String
[Code]....
The commented out line is what I can't get to work and I'm thinking that is what I need to work.
