Code For Dividing A Stopwatch Result By 60 Program 2008?
Feb 22, 2010
I have a stopwatch in my program. I start the stopwatch with the start button I created. When I stop it it gives the results of the time in a label that I have named labelTime. I have a Calculate button I have created. I also have a label I have named calcResult. I want to click the Calculate button and divide the stopwatch result (labelTime) by 60. I want the results of this calculation to be displayed in the label calcResult. I keep getting errors saying labelTime is a string value. I believe I will need my calcResult to be a Decimal.
I'm trying to do this division and the result to be displayed on a eight decimal number.
Dim r1 As Integer Dim r2 As Double r1 = Val(TextBox16.Text) r2 = r1 / 60 TextBox18.Text = FormatNumber(r2, 8)
The value or R1 on this case is 273.4 but it varies according with the result obtained so I can not allocate a constant number to r1. The problem is the result that I am getting is 4,55000000 instead of 4.5566666
I am using a background worker, it runs fine but it does not shows the result. i am using jmcilhinney source to work it out.. have a look.
VB Imports System.ComponentModelImports System.Text.RegularExpressionsImports System.NetImports System.IO Public Class WorkDialogue Private _result As Long = 0L Public ReadOnly Property Result() As Long Get Return Me._result End Get End Property Private Sub
[CODE]...
And the button codding in other form:
VB Using dialogue As New WorkDialogue dialogue.ShowDialog()TextBox2.Text = dialogue.Result.ToString() End Using
If at all possible, how can my app detect the number, physical location, and size/resolution of monitors in use so as to define the program's parameters? Secondly, I have created a stopwatch variable ("Count"). I can't seem to get it to function properly unless using full seconds. In the following code, I have tried to use a fraction of a second (like .5) and using "count.elapsed.milliseconds = 500" and the program doesn't act like the code is even there...
Code: Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick If count.Elapsed.Seconds = 1 Then Run() End If End Sub
What is the proper way of working with percentages and DataGridView and dividing by zero..In my code I am attempting to divide two numbers, sometimes one of the numbers is zero..Then I need to add a column to my datagrid, I think i need it to be decimal? So i can sort it later. I had it as a string and everything worked fine excpet i couldnt sort properly.[code]If I change column to Double it handles it fine, then i am not sure how to read the value as a percentage?
I am writing a Windows Forms Application using Visual Studio 2008 Pro .NET version 3.5 with STRICT and EXPLICIT options both ON.
I am having trouble using ".Start()" and ".Stop()" for my stopwatch method from other methods. I have tried several different methods of writing the line that calls the start and stop, but none work, and VS keeps sending me in circles with its correction suggestions.
Form Level vb Imports System.Diagnostics Class Level
[Code]....
and promptly gives me the same error with no options for correcting it. The same thing happens for the stop command.
I'm having trouble with a Stopwatch one one of the user's machines. I'm using the Stopwatch class to track time elapsed on one of my applications, and it seems to work fine on everyone else's machine, but on one machine it goes really slow. It's probably 1/3 or 1/4 of the actual time elapsed.
Here's the
I'm using the timer to update the textbox that displays the time elapsed of the stopwatch every second.
Partial Public Class Private WithEvents breakTimer As New Timer Private breakSW As New Stopwatch
UInt32 a; int k = 0; a = 0x9E3779B9; a += (UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24));
After above code is ran, "a" contains "228452386" But the following same code in VB.Net results in "Arithmetic operation resulted in an overflow". Basically the last statement is returning value "1868983913" so the runtime error is generated.
Dim a As UInt32 Dim k As Integer = 0 a = &H9E3779B9UI a += CUInt(AscW(url(k + 0)) + (AscW(url(k + 1)) << 8) + (AscW(url(k + 2)) << 16) + (AscW(url(k + 3)) << 24))
note the variable "url" in above code could be any string and it is same for both codes.
EDIT:When I run the following statements in both C# and VB.Net than they both return same value
Both statements return value "1868983913" for "url" "info:microsoft.com". But when I run complete statement with a += ..then VB.Net gives error while C# returns value "228452386".
As of right now I am getting no compile errors with my code, everything runs they way it is supposed to go except for one minor detail. I have a private function named MonthlyPayment() that does a calculation for a loan. The calculation runs as expected and I get the correct results by typing in Console.WriteLine(MonthlyPayment()) but it is not in currency format. To fix this I set FinPayment equal to MonthlyPayment [FinPayment = MonthlyPayment()] and typed in Console.WriteLine(FinPayment.ToString("C")), But this just gives me NaN as a result.
Here is my full code: ' The following code was created for McBride Financial Services to use to amoritize loans. ' This console code will calculate and display the monthly payment amount to fully amortize a loan. ' This console will prompt the user to input values for the loan amount, the term length, and the rate. Module Module1 'Declares strings used for user input values [Code] .....
One the click of a button the stopwatch starts, then on the click of a second button the stopwatch stops then states either in a msgbox the time taken between the two button clicks.
I am trying to create an application for a wire company that sells spools of wire for $100 each. The normal delivery charge is $10 per spool. Rush delivery costs $15 per spool. The user should enter the number of spools ordered in a text box, and check Rush Delivery box if rush delivery is desired. When the Calculate Total button is clicked, an input box should appear asking the user to enter the number of spools currently in stock. If the user has ordered more spools than are in stock, a portion of the order is back-ordered. For example, if the user orders 200 spools and there are only 150 spools in stock, then 150 spools are ready to ship and 50 spools are back-ordered.
Attached is the code with comments on what each function is supposed to do. I dont know why but the form always returns zero.
'Declare variables
Public intNumberofSpools As Integer Public intBackOrder As Integer
I have a fairly small double and a fairly large double. When I divide the large one by the small one and display it with Console.WriteLine, it always shows exponential notation. Can I display the non exponential notation form?
How easy it is to "split" a bitmap into separate parts?Here is a bitmap that was generated by a program - the red pixels that you see are purely red, there are no other colours.I want to know if the left side is "redder" than the right side. (Actually I want to be more precise than that (but I can figure that out on my own))So, I think that "splitting" the bitmap up into sections like this: would be the best way to do it then I can count the red pixels in each section.Here is the part of the code snippet that produced the bitmap you see above:I think I might be able to modify this easily to count pixels, if I know how to split the bitmap into section thingies.

1. Doctor Start Time 2. Doctor End Time 3. Doctor Appointment Duration
I want a 4th combo Box that will Start from Doctor's Start Time upto Doctor's End Time with the interval of Appointment Duration eg. Suppose the Start time is 08:00 and End Time 10:00 with 24 hr clock the appointment duration is 30 mins then the 4th comboBox should Display

I am trying to format a Function Code so that it returns a 4 digit result no matter the entry by the user (i.e. they enter 540, stores 0540 in the database). While looking online, I've found the format function, but when I use it, it returns 540, regardless if I enter 540 or 0540. [Code]
im trying to learn how to made stuff with currency.For example:I divide 10.000$ by 12 Months, rounding with 2 decimals i have 833,33 $.If i multiply 833,33 $ * 12 i got 9999,96 $, so there is 0.04 of possible loss. Rounding the 9999.96 with 2 decimals of presition i got 10.000 $ but that's what i don't want since 0.04 is a loss.Im using SQL Compact 4.0 as database, the price_month table is decimal(18,2)
Here is my code:
Dim price as Decimal = 10000 Dim pricemonth as Decimal = Math.round((price/12),2) ' 833.33 Console.Writeline(pricemonth*12) ' 9999.96 Console.Writeline(Math.round((pricemonth*12),2)) ' 10000
I've came across to quite an unusual problem with dividing integers with double variable. I've created For loop where to sum-integer interval -double is added. When sum reaches certain number text is displayed as showed below:
I was wondering how I can make textbox1 get divided by textbox2 at the click of button1. The number will go into textbox 3. I was also wondering how I can make the number round up or down. I also want all three text boxes to only accept numbers.show me the code in an easy to read format.
I've read a lot of different questions on SO about multithreaded applications and how to split work up between them, but none really seem to fit what I need for this. Here's how my program currently basically works:
Module Module1 'string X declared out here Sub Main()
[Code]....
This is only a rough outline of what actually happens in my code by the way.
My problem being that if multiple threads start running Main2(), they're dealing with the same X value as in the other threads. The loop inside of main2 executes multiple times per millisecond, so I can't just stagger the loops. There is often duplication of work done.
How can I properly divide up the work so that the two threads running simultaneously never have the same work to run?
vb Private Function calcArea() As Decimal Dim height As Decimal Dim width As Decimal ' assigns user input from the two text boxes to the two variables Decimal.TryParse(heightTextBox.Text, height) Decimal.TryParse(widthTextBox.Text, width)
[Code]...
All I did is change the multiply symbol to a divide symbol and now when I try to divide the two Decimal variables Visual Studio says, "Option strict on disallows conversions from 'Decimal' to 'Long'." Not sure where this conversion is happening.I know I'm missing something simple (once again) so if anyone has any advice please let me know.
