I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
View 17 RepliesI'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:

Basically, I'm creating an application which takes a list of words in .txt format, such like this:
Abc
Def
Ghi
Jkl
mno
What I want to be able to do is modify the words, one by one, so that I end with
Abc1
Def1
Ghi1
Jkl1
mno1
or whatever the user wants.
I created this app in C++ to get the logic, since I am more confident with that
I have a text file with thousands of entries of 11 digit numbers. With a button click I need to import the data into my form in a texybox, read the first entry, run an algorithm and place the result as a new line in another textbox. Then move to the second entry and so on.
I am able to read the data from the file and place into a textbox but I am having trouble with reading each entry line by line and running the algorithm.The algorithm that needs to be ran consists of reading each character one at a time for each line and is as follows:
ENTRY example: 12358458754
The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first character and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of the "odds" which were summed then multiplied by 3.The total result needs to then be divided by 10 and the remainder needs to be subtracted from 10. It should be something like this: (10 - ((sumOdds * 3) + sumEvens) mod 10))
I must use streamreader to read text file line by line into array.

Dim numbersarray() As Double

To read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim FILE_NAME As String = "C:UsersOwnerDocuments est.txt"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim TextLine As String

what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.

I'm storing a multi-line text file (in .dir format) in the directory the user chooses, and what I need to do, is when they import it (which my program can already do) I need it to find the end of the file (line) and then read that line, that line will be a number which corresponds with a number system.

how to read text from a listbox line by line and put current line in a label?
View 3 Repliesa user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I have a textfile wich my app will have to read.The textfile will be like this
Hello=Bye
SeeYou=SeeYa
GoodMorning=GoodAfternoon
And so on, each line in the textfile will consist of two words seperated by a = Now I want to load this textfile and then be able to use each line and have a name for the word on either side of the = and then do something with line 1 word 1 and then do something with line 1 word 2 (word 1 beeing the first word before the = and two beeing the one after the =)
For example I have a strint containing text with more than 1 line. For example:
"Hello How Are You"
I want to read a specific line of the string, if I choose to read line 1 of the string in a messagebox then the word "How" will probably pop up.
