I just learned basic arrays, I'm writing a program the allows Professor Carver to display a grade based on the number of possible points he enters in the inputbox (strMax). Then the user enters the points he earned in the textbox (dblPoints)
Then I solve the percentage. dblResults = dblPoints/CDbl(strMax) The first step is to store the minimum percentage points in one dimensional array. I did that. The second step is to store the grades in one dimensional array. I did that. The arrays should be parallel arrays. Having trouble with it It then should display the corresponding grade from the strGrades array Not done. I'm having trouble to display arrays in that are parallel.
Haveing troubles with an assignment. I am writting code that will allow user to enter a score and the program returns a grade based on the score entered. I can get it to work using "IF" statements but want to use code for ranges. My "IF" code is as follows.......
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.

Those are the two arrays now when i try array.sort(strflavor,decamountsold) or array.sort(decamountsold,strflavor) they are not arraigned properly. I am trying to get them to sort by which flavor sold the least and which flavor sold the most. However when i sort them, the flavors are not matching up with the decimal values.
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:
In Visual Basic 2005 is it possible to parallel sort three or maybe four arrays? I have a function that is trying to accomplish this but it only parallel sorts the second array with the Array that it is being sorted with. Here is the code
Sub ParallelListBoxSort(ByVal byList As ListBox, ByVal otherLists() As ListBox) Dim ii As Integer = 0 Dim a As Integer = otherLists.Length
[Code]....
'listToArray' is just a function that converts a list to an 1-Dimensional array and 'setArrayToListCollection' just puts the array back into the appropriated list.
Ive been working on a checkbook application for my visual basic class and I'm a little stumped..
To preface, the values I need to mess with include:
transaction type (checking or deposit) DTP check number ("dep" if deposit)
[Code].....
Below is the Change I need to make to my program...
"You will create a set of either collections or arrays (your choice but use just one or the other--don't mix them) scoped at the form/module level. These structures will store all of the input data needed for your checkbook transactions except for the running balance which will continue to be stored in a single module-scoped variable. That is, every input that users made in Assignment 3 will be stored in one of these arrays but you will not store any calculated values. You will not store the transaction type but will store "Dep" or a number in the check number array which will also indicate the transaction type. The Record button will add the current sale's data to these structures using either ReDim for the arrays or an appropriate technique for the collections. (You must ReDim your arrays so that the have just enough space for the data that is in them. Declaring the arrays with a large size with no facility to resize them is not allowed. Don't forget to use the ReDim Preserve syntax to retain the existing array contents when you resize them.)"
I don't know if I make a single array for all the values or if I create a separate one for each. If its a separate one for each I don't understand why an array is needed.
I posted earlier about making a form with an inventory menu I realized i wasnt doing it the wrong way I am suppose to use 3 parallel arrays for Inventory Name, Quantity on hand, and Price. And then Im suppose to make four buttons recieve, ship, value, and print and it suppose to update the new quantity on hand text box this homework is really getting on my nerves Ive been tryin to do it for 2 weeks this is what i have
The exercise prior to this one had us use two parallel arrays that store a letter grade (A, B, C, D, F) and the minimum points needed for each grade. The user input the points earned by the student and the program shows their letter grade. It took a minute, but I got that one done, and it does what it's supposed to do.This exercise has us modify that exercise to ask for the (via InputBox in MainForm Load event) total points possible. The grade is then determined by percentage of the total points possible. For instance, if x is the user input, an "A" would be 90% of x.
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.
I have to write a program using 2 parallel arrays representing grade point and grades. The grade points range from 0 to 500, however, we are only to use the minimum points per each letter grade in " points " array. This is shown in the code below. You then enter a number from 1 to 500, representing the grade points, and in turn it spits out your letter grade.My problem is this. When I enter a number, say 200, I get a letter " D " grade instead of an " F " grade. It appears that every number range I enter gives me one letter grade less than what it is supposed to be. Also, any number 450 to 500, representing an " A " grade does not even register in my Grades Label.
I have a service that scans network folders using a parallel.for method. However recently I am finding if I stop the service then while windows says the service is stopped the process is still running in task manager. However it is at 0 cpu and the memory does not change. If I try and end the task (even a force in command prompt) it just says access denied and i have to reboot the server. What would be the best way to make sure everything terminates? I thought of adding a global Boolean that in the stop procedure it turns true and part of my parallel code will check for that and call s.stop.
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 ?
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. "
Private Sub states_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load state(0) = "Alabama"
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.

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
im using tasks parallel library in .net 4.0 i want to have the ability to specify a task for each core independant of the other cores. usually in TPL, i create a task and i tell it to run in parallel, i have no control over the number of threads created nor can i control the number of cores to participate in the parallel task. also, i cant specify each particular core a different task.i'd like to know how to achieve this in TPL if it is possible.
I have been reading up on the parallel programming and even now still a little confused on the whole concepts. Lets say I have a single project with about 5 classes that interact and have local variables in methods and variables accessible to all methods in a single class and even 1 or 2 variables accessible to all classes accessed through instantiation. Now using threads I know that global variables would be overridden by multiple threads if there were no locking applied but local variables to a method/function do not, right?
So if I ran the project multiple times meaning as a new process, the methods and variables would be thread safe right and no data corruption occurs? So to implement parallel programming using the task factory, if I created a project that basically creates tasks and each task is basically running an instance of another project, then shouldn't the variables and data be thread safe and safe from corruption? But what if I had the output files and they named by Output & datetime.now.tostring, would there be conflict issues and I ask this knowing that I have seen this happen when trying it. [Code]
Private Sub error_out(ByVal line As Integer, ByVal err_col As Integer, ByVal err_msg As String) Dim ln = t_erori.Rows.Add

I suspect this is because it's trying to add the same row twice. How can i make this work ? Or what else method could I use to do this ?
I need this datatable because my app is writing some results in there, but any other method to store the results that works with parallel.for would be ok.
I have a class written in C#. In it I want to run a certain function in parallel on a list. After it completes on each item I would like to update a progress bar. However, I get very odd behavior from my program. It executes the event and reaches my sub but never proceeds to actually execute any code. Instead it just freezes. (I've mixed vb.net and c#. It will be rewritten at some point)[code]So for some reason I get it to enter progressBar Counter on each item in the list but it never exists. Instead it just keeps the form frozen.
Im trying to learn how to use a Parallel.For loop. Ive got a big for loop, that i need to run parallel, and am trying to use a Parallel.For loop for the first time. When I try using this code, I get that it cant be called using these arguments. The old way to write this would be:[code]I dont need to return anything to the for loop, Im just trying to iterate m, running in parallel. Where am I going wrong?
