Using Text Files In VB?
Jul 22, 2011
I have a combobox with several countries in it, Canada, USA and France for example. For each city I have a text file which contains another list of cities for each country. When you chose a country I want to show this txt file of cities in another combobox. It appears I can run this in the VB2010 enviornment but when I go to publish it I get unhandled error messages. Below is a code snipet..
Private Sub btnAccept_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAccept.Click
If ComboBox1.SelectedIndex = 0 Then

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.

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 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 am a beginner in vb 10 (vb.net). I am trying to create a text file "something.txt" and write a long string to the file. My string contains formatting chars newline and carriage return, which I want to keep.
I tried:
FileToSave.Write("test" & Chr(10) & Chr(13) & "test2", RichTextBoxStreamType.RichText)
using the System.IO.StreamWriter method but the line feeds and carriage returns are lost and all the text is just streamed together with no formatting.
Where 'FileToSave' is the path and name of the file. Note: I know I can use the vbnewline instead of chr(x) but this is not the issue.

An application I am developing creates a directory and text file within the directory. A button is then coded to add a text string to text file. An error is issued stating the file cannot be written to as the is open to another process. This suggests the file needs to be closed before it can be written to.
