Unable To Do Gridview Calculation
Mar 15, 2012
I am having some problem with calculation in datagridview. i have 3 columns in datagridview which are Date,location,Payment. What i want to do now is i want to calculate the total of the payment and my total is a textfield out side the data gridview under the payment field with the label total. This payment is for a specific person who books a photo shoot.suppose when customer 1st comes in the store he pays 30 pounds and second time he pays 20 pounds so total should come up as 50.every time customer comes total for that particular customer should change.

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

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...
Public Function PayTotal(ByVal cnthours As Double, ByVal standpay As Double, ByVal overpay As Double) As Double
