Creating A Series Of Text Files?
Jun 27, 2011
I am trying to write a program that writes information from texts boxes to a text file on the users hard drive. I would like to create a new text file if one already exists, for example if text1.text exists, it creates a new text file called text2.text, then if text2.text exists it creates text3.text and so on. Here is what I have so far:
[Code]...
I've tried fooling around with if statements to create a new file but it doesn't seem to be working. Additionally, How can I write to a new line in a text file. For example there are 4 text boxes and each string from each text box gets its own line.

I have a series of text files in multipule diffrent sub directories. I found the following functions on the Internet:
CODE:
The functions will make a direcotry tree in my debug window, that looks something like this:
CODE:
What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.
Something like this:
CODE:
Any ideas on how to acomplish this?

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.

what i am doing is downloading headers from a web server using a tcpclient which works great the headers describe diffrent files and there are hundreads per file, if i download the headers and write them to a text file using a streamwriter it works great, but i need the headers to be in a text file depending on the name of the file in the header, so i need them grouped together, i am now using streamwriter to write the headers to seperate textfiles depending on the filename in the header but it is reallllyyyy slow for some reason, im not sure if it is because it has to load each file then write to it? i only have to append the new header to the end of the text file i dont have to open it up and read through it.

I have a series of files in different folders. Is there any way to open these files automatically search for lines containing fullBod and delete them completely? Then, close the file and save the changes? This tool should be able to process several files at once in a directory. clock [t= 83] SetSwitch [figure= fullBod switch= walk_across state= 01]

Ok, so today I wasted a bit of time looking for ways to use a text file to save login information. Basically, there are two fields, username and password, and two buttons, sign up and log in. When you click the log in button, I want it to verify the information entered in the fields, and when you click sign up, I want it to add the information to the file. It doesn't seem that difficult, but I'm have a lot of trouble finding a way to do it. I would be very grateful if I could find assistance with this on these forums.
P.S. If it was my decision it would obviously be using a database, but for this particular program I need to be using text files.

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.

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 am attempting to add code to an existing script that will add the log messages to the log txt file in order to determine which loops are running in the script. But all I get is either a blank log file or only one line which I believe is the last loop that ran and not a concatination of the loops that ran which I know is more than one.
How do I create a log file that will continualy grow?
These log calls are placed in each of my loops (I am just showing 2 as an example.)
log ("in loop 1")
log ("in loop 2")
etc

I am planning on sending some of my friends and colleagues a copy of a program that I made. For this program I was going to include a .zip file of some extras for them to look at. Is there a way in VB.NET to create a .zip folder, copy things from the program's resources into the .zip folder, and then later on be able to unpack them? PS - The purpose of this is to copy items from the resources into the .zip folder so that I can send everything in one program.

I recently started having problems when creating new schema (xsd) files inside Visual Studio 2008. When I create a new schema file, the only file that is created is the xsd file itself. Neither the designer.vb or xsc files are created, which of course makes it unusable. The problem seems to be caused by the fact that the CustomTool property in the property grid is missing. If I change the CustomTool property to MSDataSetGenerator, then it immediately runs and creates the missing files noted above. How do I reassociate the CustomTool with Schema files?

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 am using Visual Studios 2005 and I am creating an application for our IT Security.Part of the program is for documents and procedures. What I am trying to do is automatically create a menu based on the folders and files. So far I have it taking into account the base folder and one subfolder level and files within it, but I want it to automatically also take into account any subfolders and files that may be added at a later date without having to replicate the code below for each new level. My code is as follows, it is very messy as I am not a programmer.
