VS 2008 Writing Text Boxes To Files / Formatting And Headers?
May 29, 2011
I'm working on my very first VB 2008 Express program, having a little bit of experience with VB 6.For my first VB 2008 program, I'm starting out simple. I have two text boxes, named Title and Director.You input text into each text box.I also have a button named GENERATE, which generates a text file named c.est.txt and stores the text box material.[cod]I know how to do this with VB 6, but not with VB 2008, and my research hasn't come up with an explanation of how to format this correctly.So how do I revise this code so that there is a line for each text box string, how do I get rid of the System.Windows.Forms.TextBox stuff and replace it with my own headers, and how do I double-space between lines?

I'm getting a problem when writing text files using StreamWriter. The files read fine and they write fine if I'm not overwriting an existing file. They also write ok as long as I'm not writing over a file that only has one digit at the end of the name. For some reason when there are 2 digits at the end it crashes when I'm trying to save over an already existing text file. Here's my code.
StringForTextFile = "C:" & Folder4PS & "" & IDCodewDashOrN & "Series" & Series & "ScreenNumber" & ScreenNumber & ".txt"
LblTesting.Visible = True ' Testing
LblTesting.Text = "StringForTextFile = " & StringForTextFile
[code]....
above but 've tried all the different Encoding possibilites. Unicode, UTF32, UTF8, UTF7 as well as without those parameters listed where the close parentheses is right after StringForTextFile. I get the same result. If I'm writing a new text file that doesn't exist, then no problem or if I'm writing over an existing text file but it has 0 to 9 at the end then I'm ok but if I'm writing over an existing file and there is 10 or above(haven't tried triple digits or all values) then my application crashes. You see the test label in the code above because I was looking at exactly what file it was trying to overwrite and it is just as it should be.
Should I be using a different procedure? An example of a string that would cause a crash for the string StringForTextFile would be:
C:Name of My AppSeries1ScreenNumber10.txt
If it was being written for the first time then no problem or if the 10 at the end was 0 to 9 then no problem also. I've also tried and originally had it set up where there wasn't an If File.Exists(StringForTextFile) = True Then statement. It just always used the same code whether writing or overwriting and I wasn't having a problem that I remember. For some reason I started having a problem recently and I put the alternate methods of writing in.

Problem 1: I am running into a problem with my program that when UAC is active on Vistaaccess to C: and Program Files is not allowed. My program writes text files as a user types. Is there a safe place to write files to that may be some sort of standard instead of throwing files all over the place? Like maybe somewhere in the user's default folder's or something?

How do I start writing a program that has 6 text boxes. A person would enter a member number if they have one, number of movies rented at $1.80 a piece. A Text box should then display Total Rental Price, and if a member number was entered, a 10% discount is given (the total of the discount shows up in another text box) and after there discount is applied the Amount Due is displayed in yet another Text Box.
My boxes are named:
memberNumberBox
moviesRentedBox
rentalPriceBox = $1.80
totalPriceBox
discountBox
amountDueBox
This is all supposed to happed when the customer clicks on a calculation button named: Button1
This is what I have so far, but I don't even know if this is correct, as I am getting 1 error relating to a name not being declared. Please help and clue me in to where to start!
Public Class Bonanza
Private Sub memberNumberBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles memberNumberBox.TextChanged

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

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 am having difficulty writing to cvs files. My application is a text parser that scans a txt file, removes punctuation, and then stores the individual words in another txt file for later analysis. My end aim is to process txt for semantic similarities. I'm very new to this so my code is very chunky But I'd really like to pull each sentence from txt file, put into an array, and then place each array item into a CSV file with commas between words.

I am witting an app that will generate batch files to do an unattended installation of a share point 2007 farm. I already have a batch file I use and it's pretty big. I copied and pasted the content into my application, and I'm using the System.IO.StreamWriter to write to the batch file from the winform. [code]As you can probably guess, I'm doing all of this in my mainform code window. There are maybe 3 or 4 batch files that will be generated based on the selections made on the form. For example, I'm generating a batch file to create the OU, Group and service accounts the farm will use in active directory, I'm creating a batch file for all of the variables that will be used for the additional batch files created, etc. How can I split this up? is there a way to create the batch files without having to actually copy, paste my existing batch file content into the mainform code window? I'm using file.writeline on each line of the pasted content by the way.

I have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.

I have created a code in VB.NET to read data from text files. Data is read from a list of files, where each file is changed using a for loop. Data is written to a new text files. Each file is read one by one and written in the same way. Now, my speed of execution is very slow. I am using a Quadcore processor with only 20-30% of CPU utilization when my code runs. Is there anyway I can increase the speed of reading and writing? To read only 125 files it takes 10 minutes or more, which is very slow indeed, because in the end I need to read thousands of files and write them. Each file is approxiamately 30-50kb.
Here is my code.
Public Sub ReadRMRDataFileIntoTextFiles()

Dim customerids As Collections.Generic.List(Of String)

I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

So i wrote a script which does a few things and richtextbox2 is updated as follows:
a = 27,130,000,000
b = 2,930,000,000
c = 4,290,000,000
Problem is, when i copy the contents of richtextbox2 to the clipboard using "clipboard.settext(richtextbox2.text)" and then open up note page, and paste the clipboard contents, it is wrapped wrongly and i get the following in note pad:"a = 27,130,000,000 b = 2,930,000,000 c = 4,290,000,000"
I am using "system.envoronment.newline" in my code to start a new line.

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

My application creates a file by writing to System.AppDomain.CurrentDomain.BaseDirectory() & "data/" & filename...Now this works fine usually, but I just added a setup utility to the app, so now it installs to the program files directory. It installs correctly and creates the data folder, however when it tries to write the file it gets an exception "unauthorized access".

if this is not the right area to be posting this. I couldn't find an area dedicated to discussion about IDE features.Somehow one of my .vb files is not showing the nice formatting that is default in VS2008, such as the text colors, etc. how I can get this back? I don't know what to search for, as I don't know what its actually called. On the left you see what I want, and on the right you see what I have right now.
