arrays saving to file that if new user account is added name and email address is saved. if in the future multiple users login in whe name and email address will match correct users.
here is what i got so far....

I'm looking to be able to save and load the content from multiple structured arrays and variables into/from an encrypted file, is there any reliable source of information or tutorial that I'd be able to use for this? I've never written a program in visual basic that writes to/reads from a file.
I'm using microsoft visual studio 2008.
Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
[Code]...
So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
trying to save users names and passwords from input boxes and save it as arrays in text file that in future multiple users will log in with their names and passwords
have this code so far but doesnt realy save the user info to file, dont even create file.
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code].....
lads, I'm having problems with saving user input to text file. Need use the streamWritter to write users names and passwords to text file I gues the arrays would work out but the code is mess and I'm stock with this:
[code]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim file As System.IO.StreamWriter
[Code].....
I'm trying to solve a problem I'm having with writing in a text file using 2 arraysthe first array is the normal text, line by line.g.
dim arrCode as string()
arrcode(0) = "This is the first line"
arrcode(1) = "The second line etc."
[code].....
I've been making a program whereby users names and numbers must be stored in external files. At the moment I can get the names to read and write to a file with these lines:
Imports System.IO
Public Class frmDefaultMenu
Private Sub frmDefaultMenu_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
Where each line has a name, a seaparator (,) and then the corresponding number.
When the program loads I would like it to be able to access that file, and store all the names into an array named ExistingUsers() and all the Numbers into an array called ExistingNumbers(), and then when a new name is added in the textbox, it is assigned the number "100" and placed at the end of the array, then when the application quits OR straight away, the external files are updated.
I have been trying to find out how to do this for days now, so I am finally asking how. I am newish to programming. Here is my problem.
I am trying to extract x,y,z coordinates from a text file arranged as such:
x,y,z
x,y,z
x,y,z
etc.
I need to be able to extract the x column into an array, the y into an array, and the z into an array. I learned how to pull it into a string, and how to split for every line, but i don't know how to split after each comma and separate them.
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)

View 4 RepliesEven a primer on just reading/writing to a text file would be golden. The array confuses me further, but understanding the data is primary.
Basically, we're writing a program to manage inventory for a bar. Fields and a few lines are below. The delimiter is "||"
So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.

I'm trying to read data from a text file with multiple records and fields separated by tabs to store into arrays, which I later want to output into a textbox on the form. The problem is that with the code I've written, when I debug it it exits the sub procedure when it enters the first loop where the parser is reading the text file. There are no error messages, it just exits? I'm not even sure if what I've written is possible. Here's what I've written so far:

I would like to be able to read data from a text file, be able to edit it and save the new edits to that file over writing the old ones.

View 2 RepliesI need to know how to code a windows application program that will make it possible for customers to place orders online. Customers will have access to menu using a combobox,containing items available. The text file contains all menu items and the price of each item, as well as number of orders for each item. The file is created with a notepad containing 5 menu items.the first line contains the name of the item,second line contains the price and the third contains total number of orders which initially is 0. So far so good i know how to check if the file exists or not,and populating the the combobox, but ther's an instruction where i have ensure that the number of menu items does not exceed 100, and if so,should display an error message.and should validate to ensure that the total number of orders is>0,if not,re display the input box with a suitable message. Then on the save(menustrip),should write the whole textfile from arrays in memory,clear the combobox,display the message. Also has a process payment button where it should read through the arrays with a for next loop,then shouold write function called amount due,which recieves the total orders as a single data type,where the value for amount due is calculated as total orders*price.CAN SOMEONE PLEASE HELP ME OUT SINCE IM A BEGINNER IN VB2005.
View 1 RepliesI have learnt how to create a basic random word generator. I now want to take this further but I would like to know if what I am thinking of is possible. I am in the process of wanting to create a random name/word generator which reads/loads an array from a text file. think this part I will be Ok with as there are some vids and tutorials about. However, I wish for the text file to have multiple arrays and then dependant on the day and time of the day, only a string from the current time array is loaded. Does that make sense and is it possible? I am happy to spend time learning how to do this but only if it is possible.
View 3 RepliesI have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
I have two different 2-dimensional arrays. I assume the setting i need to save them to is a string setting, as is the cast with regular integer arrays. The first 2-d array I need to save is an integer, the second a decimal.
Let's say the settings are called my.settings.2darray1 and my.settings.2darray2
Let's also say the arrays are:
vb
dim 2darray1(50, 99) as integer dim 2darray2(50, 99) as decimal
What would the code be to load each array and save each array?
I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.
Dim comp(maxsize) as ccircuits[globally declared]
Const maxsize = 50

I'm currently making a program that will be used to practice German. It reads from textfiles that have English words (noted by # prefix) and German words (noted by $ prefix). An example of this:
#hello $hallo
#good $gut
#evening $abends
The way it currently works is it loads a text file, finds all # and splits to an array called "English" and finds all $ and splits it to an array called "German" What I want it to now do is feed the "English" entries into textboxes on the left, and "German" onto textboxes on the right so I can then match them out and make a sort of memory game out of it. Unfortunately, I don't know how I would loop an array through multiple textboxes. Conveniently, the textboxes on the left have even numbers, and the ones on the right have odd. Is there a way to possibly find all evenly numbered textboxes and loop "English" array entries into them, and the same for "German"? I've realised this has now gotten a little convoluted, but hopefully somebody understands. I can screenshot the form for better explanation, and copy my existing source code if anybody wants it.
