Creating A Program For Which Will Calculate The Time Taken For A User To Make A Number Keystrokes?
Feb 18, 2012
I am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.
Public Class Form1
Dim dteStart, dteFinish As Date
Dim span As TimeSpan

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I need to calculate the location of intersections between multiple date ranges, and the number of overlapping intersections. Then I need to show which date/time ranges overlap each of those intersecting sections. It is slightly more complicated than that so I'll do my best to explain by providing an example. I am working in VB.Net, but C# examples are acceptable as well as I work in both.
We have several high risk tasks that involve the same system. Below I have three example jobs named HR1/2/3/4 with start and end date/times.
HR1 {1/6/2010 10:00 - 1/6/2010 15:00}
HR2 {1/6/2010 11:00 - 1/6/2010 18:00}
HR3 {1/6/2010 12:00 - 1/6/2010 14:00}

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

I want to create an application that able to calculate the total time the user (i.e. myself) spent on a particular application, for example Firefox. And this application should display warning message if the user spent a lot of time on Firefox (for example 1 hour or more)Reason: I'm a VB.NET developer. During my working hours, my main tool is Visual Studio and I suppose to do coding. But I need Firefox occasionally to access internet (particularly SO and other sites) to find solutions for my programming problems. The problem is I addicted to SO and SO sucks my time for hours until I have forgotten that I suppose to continue coding and not browsing the SO site.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
Quote:
Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click
Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")

I'm trying to capture 4 keystrokes from the user and store them in an array. Once the 4 keystrokes have been entered, I would like to make it so the user can no longer enter anything, or at least have it show up on the screen.
Here's the logic I have so far:
For count As Integer = 0 To 3
Select Case e.KeyCode
Case Keys.D1
recOrder(count) = 1
[Code]...
What I wanted this code to do was to count the number of key presses and what keys were pressed, and compare that array to a predetermined array.Edit: I forgot to mention that even though the array has been filled with key presses, when the user hits a key, the screen still updates. Also, this code is in a Keydown event.

if you want to make program to calculate the result of brackets math question , as 6+(9+(5-(1+(2+1)))) , and you made 2 buttons representing ")" and "(" , and you want when the user clicks on the "(" button it just applies that the number before it to be stored in a place like a label such that the program calculates numbers after it and then calculate the produced number and the label number , something will disallow you that the questions with many brackets as the mentioned one above 6+(9+(5-(1+(2+1)))) will for example store 6 and plus sign in a label but after that 6 will be placed by 9 because there is another bracket after 9 , so the question will be calculated false , more clarification for my question is the way brackets are made in the windows calculator so i want a coding idea to make the brackets like in the windows calculator

Write a complete Visual Basic program to do the following: Joe's Pizza Palace needs an application to calculate the number of slicesa pizza of any size can be divided into.
The application should do the following:
Allow the user to enter the diameter of the pizza, in inches.
Calculate the number of slices that can be cut from a pizza that size.
Display a message that indicates the number of slices.
To calculate the number of slices that can be cut from the pizza, you must know these facts:
Each slice should have an area of 14.125 inches.
To calculate the number of slices, divide the area of the pizza by 14.125.
The area of the pizza is calculated with the formula: Area = π r2
Note: The π is pi which is equal to 3.14159.The r is the radius of the pizza. Divide the diameter
by 2 to get the radius.
Form:
The application should be done form-based. You may design your own form. It must have the following:
a label indicating that it is Joe's Pizza Palace
a field with label to enter the size (diameter) of the pizza
a field with label to display the number of slices
buttons to calculate the number of slices and to exit the application
Output:
Use the following test data to determine if the application is calculating properly:
Diameter of Pizza Number of Slices
22 inches 27
15 inches 13
12 inches 8
Requirements:
Name the project Pizza.
Be sure to include your name included in a comment
No credit is given for a program that will not execute.
All rules of academic integrity should be applied as stated in the syllabus.

I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

I was trying to make a program which displays two chars A and B on the screen. Using the WASD keys, it lets you move the A char around and using the arrow keys it lets you move the B char around.
I wrote the following:
Module Module1
Dim Box_A(1), Box_B(1) As Byte
Dim Allow_Draw As Boolean
[Code].....
When I run the program, if I press any of the WASD or arrow keys the corresponding char doesn't move. To make it move, I have to hold down any of its keys for a bit after which I can move the char just by pressing its keys. But then, I have to do the same for the other char.
So, if I want to move B I have to hold any of the arrow keys for a bit. Then I can easily move B just by pressing any arrow key once. Then to move A I have to hold any of the WASD keys for a bit and then I can move A just by pressing any WASD key once.
Is there any way I make make each of the char move just by pressing its ket once?
