Program For The Calculation Of Bicycle Gears?
Jan 30, 2010
I am having trouble with a program for the calculation of bicycle gears. you are required to enter the wheel radius the the teeth on the front sprocket followed by the teeth on the rear sprocket. On the first entry of the rear sprocket number, the program will calculate the effictive radiusand display it in a label. If there are subsequent entries of sizes for the rear sprocket then the effective radius is calculated as before as well as the ratio between the current and previous radius.

allow the user to enter a stock transaction and determine the stockbroker's commission. Each transaction includes the following data: the stock name, price per share, number of shares involved, and the stock broker's name. Assume price per share = P. The stockbroker's commission is computed in the following manner: If the P (price per share) is less than or equal to $50, the commission rate is $0.19 per share, if P is greater than $50, thecommission rate is $0.26 per share. If the number of shares sold is less than 150, the commission is 1.5 times the rate per share. Display the results in a message box, including the total commission earned.

I just need help with my Pizza Program in calculations. It keeps on adding on top of the original calculations. I did try to set the variables to 0, but that really didn't work out since the price that is shown turns out to be 0.

I'm setting up a quote calculation program for my business.I'm just a beginner with Visual Basic (2010 Express) and am finding it very interesting.I already did some reading and followed the tutorials but I'm getting stuck with my program now.
[Code]...
Make it possible for users to enter necessary data in the "new quote" screen. The data needs to be written into the database table of "new quote"Make it possible for users to lookup previously made quotes in the "open quote" screen. I want them to be able to select a quote based on "quotenumber" or "customername".They then must be able to select a quote, which will open a new window with all quote information from the tables. This information needs to be editable and savable to the databaseGenerate a PDF of a "finished" quote and mail it as attachment to a customerthe "customer information" table contains information for the quote concering address and name of customer. I want this so that users can select a customer in the "quote screen" and all other data will be filled in automatically. I also want that users
can give in a new customer in the quote screen and that that customer will be saved in the "customer information" table.point 4 is also applicable for the "material information table".

I've got a requirement where I need to calculate a value, however also refer to this value when calculating it. So I've got for example[code]...
I can see how this can be achieved in excel using Circular Reference, however I'm not sure how I go about it when using VB.Net. Is there a similar method to create a Circular Reference as in excel or any other way I can possibly work out the TotalValue?

I am making a quote calculation program with Visual Basic. Per quote there can be multiple parts/products.
What I want now:
1) insert productinformation (dimensions, quantity etc.) in one form
2) write this data into a table or something
The program then needs to calculate prices etc. but first it is important to get the data right for the calculation.
What I am thinking of myself is putting the data into textboxes and then let this data be transported to a table and have one product per line in that table. from this it can be calculated

With a Time value in my program. Basically, I am importing a travel Time from a database e.g. 3:45 so it takes 3 hrs and 45 minutes to get from a to b. I then want to double this - 3:45 * 2 = 7:30, and then want to multiply it by a cost e.g. travel is charged at 25 per hour. so it would be total travel time = 7:30. Travel cost = 25. Total Travel Cost = 7:30 * 25. In the access db, it is stored as a text field, and then imported in vb as a string.

I am using Microsoft Visual Studio 2008 with VB.NET, and in class we were assigned this project: A procedure should calculate a 2% price increase on all red shirts, but a 1% price increase on all other items. In addition to calculating the price increase, the procedure also should calculate the new price. You can use the variables strItemColr, strItem, decOrigPrice, decIncrease, and decNewPrice. Format the original price, price increase, and new price in the lblOriginal, lblIncrease, and lblNewPrice controls, respectively.

I have two money fields in a SQL database called TotalClaimed and PartialSettlementAmountRecd.They are declared as Decimals like so:
Public PartialSettlementAmountRecd As Decimal
Public TotalClaimed As Decimal
They both output the repsective amounts perfectly. I need to do a calculation on them, by subtracting PartialSettlementAmountRecd from TotalClaimed. I have tried the following, but it just outputs a random number, not the amount I require.
Dim NewSettAmount As Decimal = (ClaimDetail.TotalClaimed) - (ClaimDetail.PartialSettlementAmountRecd)
Response.Write("New Settlement Amount: £" & NewSettAmount)

I found this thread in regards to calculating CRC16 on an array.... however, it does not work probably because it was written for VB6 and not .NET. [URL] Does anyone know of a built-in function in .NET to calculate CRC16? If not, is there a way I can adapt the above VB code example to work with Visual Studio 2010?

I'm writing a financial calculator. I know that my calculations are more precise when Decimal format is used. But when I calculate 314/365, the answer given by VB is 0.8602814581, where as the real answer is 0.8602739726. This ends up affecting my calculations quite a bit.

I have an array of characters. Depending on the number selected (between 1 and 30), the program selects random characters and concatonates them into a string. Kind of like how I think a password generator would work.I want to update a progress bar to show how the operation is going, but I need to reserve 20% of the progress bar for some actions before this, and the last 10% for the actions that follow it. So there is 70% available to use. My question is:If I set the progress bar to 20% and do the following math: 70/NumOfChars, then use a for loop to add the result of this to the progress bar (pb+=result), why does the total progress NOT EQUAL 90%!

I'm trying to work on code where I enter number of hours into a textbox (txtHours) and then EITHER you press a button (cmdPay) and then the income for the week is calculated and shows up in a second text box (txtPay) OR txtPay does the calculation itself, everytime a number is typed into txtHours.
Currently, my code is trying to do the former, because I have NO idea how to even approach the second option.My problem I am having with my code, is I don't know how to properly dim my parameters, since my "button_click" code keeps coming up with this error:Argument not specified for parameter...
