File I/O And Registry :: Opening A Text File Into Multiple Text Boxes Using Loops And Arrays

May 20, 2009

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.

Read And Write From One Text File To Two Arrays?

Apr 10, 2010

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.

Set X,y,z Values From Text File Into Separate Arrays

Nov 7, 2011

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.

Reading And Writing Text File Data With Arrays?

May 3, 2009

Even 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.

how to write and update existing data.

UID||BREWERY||NAME||SIZE||FORMAT||SEASONAL||PRICE||CASECOST||CASEQTY||BREWERYLOCATION||BREWSTYLE||ST YLE||ABV||CLASS
A0101.12B||Abita Brewing Company||Abita Amber||12

Reading From Text File With Parser And Storing Into Arrays (VB)

Jun 13, 2011

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:

Aug 26, 2010

I 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.

Random Name Generator Loading Multiple Arrays From Text File

Jul 27, 2011

I 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.

File I/O And Registry :: Reading Text And Splitting To Arrays Then Echoing To Textboxes

Mar 1, 2010

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.

VB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?

May 9, 2010

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.

The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

Passing Arrays Through Fortran Dll From App Turning To Single Element Arrays?

Feb 2, 2010

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

The arrays should be used to generate all output and calculate the costs. I have gotten the program working perfect, but I cant get it so the program only reads the txt file once.
