I am making an application that requires a sequential search to search the arrays. The search searches the user's input in the array,and if found, then it's valid, else it's invalid. I have initialized the array and done the sequential search, but apparently even the wrong input is coming out to be valid.
'initialize an array

i am coding an application where I want to populate an array with the contents of a sequential file that is already populated as salary.txt in the debug folder. Basically, I want to copy the contents of that file to an array so that I may use a code to go with the intSubscript of the array. Right now it functions as just an array for this purpose, but I want to populate the array with the sequential file first. All attempts to do this, with stream writer etc and readline, I am just getting the first item in the file. I have tried to loop it and still only the first is accessable. Driving me batty, turning to the masses for guidence.[code]
I'm new to VB and my book doesn't explain sequential searches very well. I need help with the application I'm creating for school. My application has to allow the user to enter a number and then it will verify if the number is valid by searching through the list of arrays I provided.The question:Create an application that allows the user to enter a charge account number. The application should determine whether the number is valid by comparing it to the numbers in the following list: (see code)The list of numbers should be stored in an array. A sequential search should be used to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message indicating the number is valid. If the user enters a number that is not in the array , the program should display a message indicating the number is invalid.

I basically want to do what you can do for controls like the textbox where adding a new textbox automatically autonumbers itself based on the existing textboxes(e.g. textbox1,textbox2, textbox3) except for an array or some other comparable instrument.
I am trying to copy the values to another sheet but not in any sequence eg.A1,B2,C4,D7 ........and so on. I am trying this slick way of doing it by the code below ( found on the web) without success so far but I got a feeling I am close to the solution. I am new to any kind of Programming. This is my first attempt. (so a chuckle or two is ok after seeing my "difficult" problem)

getting started with creating an index search for parallel arrays. When the user enters the specific "code", and presses enter, the information in the other arrays should be displayed based on its matching index. I'm pretty sure I use "For i = " but I'm lost. I have my arrays set up like this:
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.
As a continuation of my other thread, "Finding A Pattern without a string Array (http:[url]....)", I would like to continue asking questions about enhancing a scanner with a few things:
1. Here is my code for finding signatures in a file:

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 ?
My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

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 statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "

I was wondering if anyone knows a built in method ( LINQ say or a LAMBDA expression or other way ) that you can compare2 arrays - collections that would be valid for an equivalent 3rd array - collection which is a combination of the 1st two.
My teacher as asked me to allow a user to input three pieces of information about a DVD (the ID, the title and the running time) and for the program to add that data to a sequential file. My textbook fails to explain it and I am at a loss as to where my book from last semester is located at the moment.
1. What is a sequential file?
2. How do I display information from it into a messge box?
First... does the array subscript have to be sequential? (0,1,2,3,4) Or could I pull the system date and use that? i.e. dim Beer() could have Beer(33939) for today, and then not record anything for three weeks and the next entry would be Beer(33960), etc.Along the same lines, and pointless if the answer above is yes...I'm writing a prog to handle inventory for a bar. The bar has 230 different beers at the moment. Could I create a 2-dimensional array using a product number, date for the subscript?
i.e. - for received data... recBeer(a,b)recBeer(229,33939) = 48(Meaning 48 bottles of beer #229 arrived on date 33939)SO... a is the product, b is the date. Any searches for (229,*) would provide me with the complete history of that product being received. any searches for (*,33939) would tell me all of what was received on that date.Will that work?(And yes, I'm stuck with a flat file to make this work. Much rather have a db involved.)
I have a working piece of code that checks that 4 out of 5 random numbers are in sequence. The numbers correspond to 5 dice rolls. I'm trying to learn VB and I think the code can be improved since it's so cumbersome. The sub checks to see if any of the numbers are duplicated and reassigns one of the duplicates to an arbitrary "11" which is outside of the 1-6 range of a single dice roll. Then the values are inserted in an array and sorted and the sequence check takes place. score of 30 is assigned if 4 of 5 of the (sorted) numbers are in order. If not in order, a score of 0 is set.
Code follows: Private Sub OtherScores4() 'Check if any of the rolls are duplicated and reset one of the die to arbitrary "11". If Dice1 = Dice2 Then Dice1 = 11 End If If Dice1 = Dice3 Then Dice1 = 11 [Code] .....
I am suppose to create a module level array name Product and populate a list box with the contents of a file (ItemInfo.txt) The file contains the Item ID and price of the item. (Line 1 is an item, Line 2 is a price for Line 1, Line 3 is an item, Line 4 is a price for Line 3, and so on.) The problem i'm having is when i populated the list box, I only wanted to populate the list box with the items, not everyline from the file. I guess I wanted to put elements [0], [2], [4], [6], and [8] from the Product array in the list box, but I am putting everything in there. What am I missing?here is my code so far:
' Name: Glovers Project ' Purpose: Displays the price of an item ' Programmer: <Paul J. Williams> on <February 27, 2010>
My project uses an MS Access Database, and amongst other things records the current cost of a series of categories which are regularly updated, thereby erasing the previous entry. However, I need to retain all previous costs to produce a history graph for given periods. I have considered importing an Excel spreadsheet, but having a functioning database it seems sensible to use it.
I am working on a program in Visual Basic that incorporates using a sequential access file for a ballot type program. Each type the user clicks the save vote button, the amount of votes gets stored.
What I am trying to do is in my access file is to display the number of votes as an actual number. The way my program is written right now, the name of the candidate appears as many times as the vote was saved.
for example, if perez was voted for 4 times, in the access file perez is displayed on 4 different lines. How do I display the actual number of how many time they were voted for. I'm thinking using a counter variable, but not really sure how to really implement it in. this is what i have so far.
I'm working on my graduation project and within it i need a function gives me random dates since 2008,01,01 untill now. I want the dates to show up random not sequential.. how can I do this ????
I am making c++ write a file to a folder of my choice in which it prints out my scores from a math test that c++ gives me. The problem is vb is kicking an error out

I need to test if each key is being pressed in a specific order. At the moment, I'm just doing a test between 'Escape' and 'F12.'
All works well, until I get to F11. If I enable F11 by itself, it works fine. But if I run it in sequential order, it never fires.
Each button, with the exception of one, is disabled by default. So I have a separate method that checks, when that key is pressed, if the button is enabled and if it is, it disables it and the enables the next button.
VB.NET
Private Sub DisableEnable(ByVal btn As Button, ByVal btn1 As Button) If btn.Enabled Then btn.Enabled = False
This is part of the last coding that codeorder helped me with. I didn't include this in the last post because I thought this was something that I was going to be able to do. Unfortunately, it is not working properly. In addition to the controls being removed, the control rows after the removed row should be changed so it's still in sequential order. Private Sub PictureBoxRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim RowRemove As String = CType(sender, PictureBox).Name.Replace("PictureBoxRemove", "")
Working on my major project for my last year of school worth 30% and am having issues with getting screen elements (buttons, labels, picture boxes, etc.) to update before or during a sequential sub program or function.
For example, I have a series of picture boxes that require to be clicked on to activate certain commands. Here is the code for one of the picture boxes, picX3Y0, when it has been clicked on:
If picX3Y0.ImageLocation <> imageFolder + hiddenImages(3, 0) + ".png" And imagesSelected < 2 Then If x1 = -1 Then x1 = 3
Is there an easy way to read in a comma deliminated file in VB 2010. In VB 6.0 you could read the file in directly to variables. It appears this has been removed in 2010.
