I'm new to Visual basic (which will be obvious from my question) and am writing program that does various calculations, then displays the results in a list box. the results, however, are all concatenated, end don't each appear on a new line. I tried adding a carriage return/line feed at the end buit the compiler rejected it.
I can't find any examples of creating a list box, and adding multiple entries (one for each time a loop is performed), nor of how to use columns to make the resulting display cosmetically pleasing.
Public Class Projectile_Motion
02 Dim initialHeight As Double ' Holds beginning height
03 Dim initialVelocity As Double ' holds velocity
04 Dim time As Double ' holds time
05 Dim heightVal As Double ' holds height at different intrvals in time

I'm using this code to search a msacces db and display the data in a listview.The Search is fired after the text_changed event of a textbox. So each character is a search and also each backspace(here's where the real pain is) it will search. When I use backspace its very very slow! When I use 100 or even a 1000 records no problem but this db has 10.000 + records.Whitch event can I use to solve this problem or how can I adjust the code for faster search? ALs o when I test on a windows7 system, dualcore, 2gb memory, when I press a key it will take time before I see the character in the textboxs? Its a new system and only runs this program.I use a texbox to enter for example an artist name and a combobox where the user can choose to search on artis, title, genre etc. [code]

View 5 Repliesi have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

View 1 RepliesI have written a small program to allow our employees to submit work orders. I want to have each computer on our network to be able to open the program, run it, and have the files (which are actually jpeg's of the form) saved on the server. This part works fine.
I have it loaded on the server and have tried to run it from several computers. While the program does run ok, it does not load the My.Settings items that are on the server. On each computer the program has, or appears to have its own set of my.settings.
If I go to the form in the program that allows me to add items to my.settings, and make changes they are saved, but when I go to the next computer they are not there. It only reflects the my.settings that were put directly in during program construction. (opened my.setting, clicked on the setting and added them there)
My question is,, how to get the program to stay on the server when running it so that the settings are there no matter which pc is running it? This is a windows forms program, I am using Visual Basic 2010 Express.
I am trying to come up with a way to store 3 pieces of information for each employee in the company on a daily basis. So for instance:
Day 1: Joe, 8, 80
Day 2: Sam, 10, 90
Day 3: Bill, 5, 40
Day 4: Bob, 8, 40
Day 5: Sue, 2, 50
I am very new to collections and most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
This is what I have so far.
VB

Dim iDays As Integer = NumberDaysPerMonth(Date.Now)
Dim DayNumber(iDays) As Integer
Dim EmployeeRecords As List(Of String) = New List(Of String)
For i = 1 To DayNumber.Count - 1

Your Form should use text boxes to input the employee name and the euro amount of the sales and also use text boxes to display the results of the calculations. Provide buttons for Calculate, Clear, and Exit. Display a message to the user for any bad input data.Hints - You need to declare module-level constants, declare variables, carry out calculations and use try/catch to handle any exceptions that may occur.
I want to make an application that allows the manager of the company whether the employees are truly active: screenshot and a "timer" to measure the time of the activity of the employee Can be controlled using the mouse or keyboard while the application is not active, but in execution.Is it possible in vb.net to know if the user of the machine is using the mouse or keyboard? My idea is to set a "Timer" which triggers automatically after the connection of the employee and every 10 seconds the application checks whether the mouse position has changed or a letter is entered on the keyboard except the"Timer" Will Be stopped until have a new mouse position or activity on the keyboard. But the problem is: is the application able to know the position of the mouse or to capture all keyboard input even if the application n 'is not active(not in the foreground)?

This is the Project that i have to make. Create a project that will input an employees sales and calculate the gross pay, deductions, and net pay. Each employee will receive a base pay of $900 plus a sale commission of 6% of sales.
After calculating the net pay, calculate the budget amount for each category based on the percentages given in the tables below:
Your Form should use text boxes to input the employees name and the amount of the sales and also use text boxes to display the results of the calculations. Provide buttons for Calculate, Clear, and Exit. Display a message to the user for any bad input data. Now i want to know for constants its going to be : commission sale, deductions and everything in Budget? I am also guessing that for the gross pay its going to be the" Gross pay = base pay * Commission" ?
Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

I'm an instructor trying to use data from a .txt file to list the grades in a list box. I just want to grab the data from a .txt file, list the total amount of grades in a list box, the mean (avg) and the standard deviation.
View 5 RepliesI am rewriting an old app that uses Linq. One part intrigued me...The code get the ID of a row from a datagridview.Then the code executes a LINQ that in the where-part make a selection based on the ID (which is the PK) to return a single object using .Take(1).SingleOrDefault Then this object is added to the dbcontext.Employees.DeleteOnSubmit() method and finally the Submitchanges is executed...I added a watch to the Log property of the datacontext, and lo and behold, when the delete query is executed, it uses ALL properties of the object in its where query. It should use the EmployeeID only since its the PK.
My question is, is it impossible using LINQ to execute a simple "delete from employees where employeeID = 1" That is basically what the above LINQ code does. But I dont want to to excute a select statement first, and I dont want it to delete by all columns, only by the id column, which an indexed PK.Any LINQ gurus wanna share some insight on this?
