Putting One .txt File Information Into Multiple Different Arrays?
Jun 10, 2011
i'm having issues where I can't figure out how to take a text file that was provided for my homework assignment, and put the information within it into 3 different arrays.The .txt file looks like so:tc.Amanda/Ashley have to be in the same array as well as 4/2, 166/20.This is what I've come up with for the snippet of code, and so far, it hasn't really been working right.
Dim namearray(MaxItems), rankarray1990(MaxItems), rankarray2009(MaxItems) As String
Dim Numitems As Integer
Dim sr As System.IO.StreamReader
I am developing a game and I want an options window to be used so that the user enters data into this and it carries to the main window instead of being lost. I tried it with my recent program , guess the color , but it did not work the way I thought. I thought that I could assign it to a string in a textbox to a variable and it would carry into the main window...
I want this to happen: The user begins the program by clicking shortcut User clicks options in the toolbar A new window comes onto the screen
In this window the user will select a map size then click ok the verify , radiobuttons used in this example... Back to the main screen after clicking ok User clicks new on toolbar to begin game Game is then playing...
Form1 <<< Form 2 game screen 3x3 button end turn
Form 1 New game is begun form 2 appears 3x3 button is pressed* variable is used to change map (there is only one map for now)* form2 closes and form1 shows End turn is clicked
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
I'm trying to grab information entered in textboxes. I'm trying to grab a name, an age, and a movie title from three separate textboxes, and put them into a single label like this:
"Name" is "age," her favourite film is "movie title."
after clicking the "Show" button.
I know it's a click event for the show button, but I can't quite figure out how to make the concatenated message.
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 have an online database, and I have a program to insert information into database and to login using the information in the database, now I am wondering how to take something from a database and display it in a label, lets say if I log in with my username and password I want it to display my e-mail address from the database in a label, this is the code that I have for the register:
Imports MySql.Data.MySqlClient Imports System.Data.SqlClient Public Class Form2
I Have a complex Class Structure that holds a large amount of data in the form of multiple nested arrays that I want to save to a file and retrieve everytime I use my program.. How do I do this? I am using VB10 Express.
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.
I need to add this line to a text file that is going to have other information added to it several times. I also need to add this line and have the number change every time the additional data is added.
I know how to load a txt file into a single text box, but im having trouble loading a text file with multiple output information into multiple text boxes using commas to separate the information.
I am trying to get the information inputted from multiple textboxes to save to a single text file.
Here's what I got. Private Sub btn_done_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_done.Click Dim FILE_NAME As String = "C:UsersTrevorDocumentsDraftAC est.txt" Dim i As Integer Dim aryText(2) As String [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.
I'm trying to get information from a text box into an array. I've tried everything that I can think of from assigning it to a local variable then into the array, to assigning it straight to the array, but I can't manage to loop it all together and achieve functionality.
I have to write an application that has the user input data in 3 separate text-boxes and press "OK" to save it. The user can repeat this as many times as they want.I then need the application to show the information inputted in each of the 3 separate arrays. Now I was told this can either be done by using a print page or by having another form show the information. I was told having another form would work best. I guess my question(s) are: is it possible to show the information from all 3 arrays in another form? Also, is there a link to any code that can help me out in listing information from a
I am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30} Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.
I'm new to this, so sorry if my question has been asked before. I have searched but have not been able to find, or perhaps recognise, an answer. I am using visual studio 2008 and creating an app in vb.net.
I have 4 arrays named:- account1 account2 account3 account4. They all have 4 elements.I want to assign values to the elements in the arrays in an efficient manner. I thought two for next loops would do it. [code]....
I have two listview in a separate form, basically what i want to do is whenever I select a row in my first listview the items in that selected row will be copied in my second listview which is empty.
I want to go to a class.vb file that has a function from an aspx page and I want to return mutiple arrays. Is that possible? If so, how would I call it from the aspx page and how would I return it?
I'm trying to find out a way to search multiple arrays for a specific value. I looked through here, yahoo, google and msdn and couldn't find anything specific to what I'm looking for. Don't have any sample code as I'm not quite sure where to start.
2)The program needs to access particular chunks(for example (0,20) to (50,20)
3)The program will open multiple files and process each into it's own 2D array (400,20)
What I have right now is code capable of creating the array, but no way to store the array so that I can open a new file and process that data into another large array. Someone mentioned the generics List(of T) might be a good way to store each new array as you could use the Add function. I have done some research on the List(of T) class but I'm not totally convinced that is the way to go. I'm just looking for some direction as I've just started on .net this year.
I am having trouble getting data from a text file to go into an array that I will make a parallel array for searching for data. I am not certain if it is how I state the while statement or how I stated the transfer to the array that is causing me problems. Here is my code.
Dim InfilePro As IO.StreamReader Dim InfileProNumber As IO.StreamReader Dim InfilePrice As IO.StreamReader
but it gave this error and in the details box it had this:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I have the following code... in an MDI application. [code] Various lines of code which put data into the Myinstance and then save the instance into the ArrayList.I have buttons which run procedures and functions in the formchild and also in the Class1. I need it so you can jump between formchild instances, and when you do so and click a button on that form, it will run the Class1 code but using the data in the arraylist and myinstance that was set previously by the selected formchild. Then if you switch to another child it uses data from this form. Can this be done by declaring the arraylist with more dimensions and then refer to the records with the index of the selected form instance, e.g.Selected Child is index(3)
I have created an MDIparent form and a MDIchild. There is a button on the parent which makes multiple 'clones' of the child form, each time its clicked.I also want (maybe with a module) a set of variables, and array of a structure but these are available to each copy of the child, but each copy's variables, arraylist etc contain its own data?Therefore if you select child1 the variables and array will have different data to child2, child3...etc...
Basically i have a 500 line javascript file i made that runs in grease monkey (a add on for firefox ) I'm using vb.net to "compile" this script depending on certain check boxes.
So for example. (this is part of my script)
#RegionCapsEnforcer var array=document.evaluate("//*[contains(@class, 'postbody')]", document, null, 6, null);
[Code]....
and so on. So if chkCapsEnforcer was not checked it would skip that part and go to chkRevealUrl and if that was checked would get that bit. Then once it has gone through all the checkboxes it would write the enabled bits to a text file.
