VS 2008 - The Program Keeping A Running Total?
Dec 9, 2010
I'm about to pull my hair out with this program. I need the following program to keep a running total of the total amount due by a customer for books bought. The exercise required the use of a BookSale class with 3 attributes(a quantity,price,and total due) and 2 behaviors(a default constructor and method that keeps a running total). Here is the code for the class:
[code]...
My problem lies in the program keeping a running total. The total due is displayed fine for each quantity and price but not the whole running total. For example,if I enter 1 as quantity and 2 as price and click the Add to Sale button,the Total Due value,which is $2.00,is displayed. However,if I change the quantity to 2 and price to 4,which comes out to $8.00,the $8.00 is not added to the existing $2.00. I feel like I'm missing something elementary and it's driving me crazy. I would work on it some more but it's already after 4 AM here and I need to get some sleep.BTW,this exercise is from a college textbook. However,this isn't an assignment that is due. I just got bored and decided to work on a chapter we didn't have time to get to.

I'm looking for suggestions on keeping a program that is running on a network updated. Installation consists of 15 users, each have the program on their local pc, but they all access same date from sql server. I am looking for a clean method that would allow me to update one folder on the network and for each computer to get updated when they run the program and the programs sees a later ver on that folder on the network. (Obviously I can do this inside the program itself since it won't allow being overwritten while opened.)

Anyway I am writing a program to allow the user to enter:
-size of pizza which is a combo box (CmbSize)
-type (thin crust or standard) of pizza which is a combo box (CmbType)
-pizza choice (spicy chicken, maryland etc) using a checked listed box (ChkdListChoice)
The problem I have that will probably be simple to a lot of you who are using this language frequently is that I simply want keep a running subtotal of the users choice. So for example the user chooses 8" Spicy Chicken - 3.50, then they press the BtnAddToOrder button to output it to the Textbox (TxtPizzaChoi). When the user adds the next pizza I simply want the previous pizza price to be added to this one giving a new subtotal. I have not made the price change if the user changes the size to 12" spicy chicken, the price is still 3.50, simply because I think this could make it more difficult to me and I don't have lots of time to work on this. My declarations are not all in use and i may not need them by the way.
Heres the code:
Public Class PizzaChoices
Dim price As Decimal
Dim topping As Decimal

I am trying to keep track of the total number of discounts given (whole numbers) I keep getting .75 after the first discount, and it adds .75 for every trans action after that. I have tried to pick it apart but I just don't see it. You can follow by tracking the comments that relate to the summary. I know that is an Integer but the book has it declared as a decimal so I went with it.
Public Class BookSaleForm
'Declare module level variables
Private QuantitySumInteger, SaleCountInteger As Integer
Private DIscountSumDecimal, DiscountedPriceSumDecimal As Decimal
Const DISCOUNT_RATE_Decimal As Decimal = 0.15D
[Code] .....

The pay rates for the project are:
a. Level 1 - $10.00
b. Level 2 - $12.00
c. Level 3 - $14.00
d. Level 4 - $16.00
e. Benefit Deduction Rate - 0.10
f. Overtime Factor - 1.5
For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.
When the Calculate button is clicked:
a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.
1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.
2. If the user chooses to continue processing, the focus must be set to the Hours text box.
3. If the user chooses to quit, the program must close immediately.
b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.
1. The pay rate is determined by which Job Grade radio button is checked.
2. For hours less than or equal to 40, the total pay is the hours times the pay rate.
3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.
4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.
5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal
places.
6. The focus must be set to the Hours text box.
Why i get an error when i try to run this code
Code:
Also the message box, both yes and no close the program.....

I've created a program that pulls item prices from a database. The problem I'm having right now is that I'd like to display a running total, as the program currently only displays the list of items and their prices.

For my Visual BASIC class we were asked to create a project to compute your checking account balance.Included in the project should be three radio buttons (deposit,check, and service charge), one text box (the amount),and a read only text box which will show the new balance. The balance should be calculated by adding deposits and subtracting checks and service charges; Each of these must return an updated balance. If there is not enough money to cover a check,do not deduct the check amount, but charge a service charge of ten dollars. The problem I have continually run into is keeping a running balance without using do or for loops. Here is a copy of the code i have come up with which will display only what I enter into the amount text box and put it into the balance read only text box; it will not accumulate.
Code:
Private DepositTotalDecimal, CheckTotalDecimal, ServiceChargeTotalDecimal, BalanceDecimal, AmountDecimal As Decimal
Private DepositCountInteger, CheckCountInteger, ServiceChargeCountInteger As Integer
Private Sub PrintButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintButton.Click[code]....

Had this issue I was wondering about. This is what it actually DOES then Ill say what I want it to DO. It grabs the word from a notepad I have saved in the directory, and brings it forward onto a form in designated area's and after whomever is done with the word and definition. It'll tell you how many times it's been looked up. Problem is the count applies NOT to the individual words as I'd have liked but EVERY word that has been searched for in the session.: Here's a snip-it
[Code]...
how to get the count to apply for each word individually. Either just within the session or, if possible, keep a constant running total of searched words.

I am using Visaul Studio 2010 to build a Windows Forms application to maintain a table in an SQL Server 2008 database. The table is named CASHBOOK and here are the further details:
DATE | DESCRIPTION | DEBIT | CREDIT | BALANCE
--------|----------------|---------|-----------|---------
1/1/2011| CASH BALANCE | | | 5000
1/1/2011| SALES | 2500 | | 7500
2/1/2011| PURCHASE | | 3000 | 4500
2/1/2011| RENT | | 4000 | 500
2/1/2011| SALES | 5000 | | 5500
I can use CASHBOOKTABLEADAPTER.INSERT(...) to insert appropriately, but my problem is how do I update the BALANCE column?

I want my program to use the Appacctivate with a process ID because, the window title of the program I am going to work with is changing.
I tried several thing, but I just can't seem to be able to get the processID of any running applications. I googlet it, and there a several code's out there, but I get a Null Reference Error, with all of them.
which gets the ProcessID of a running program? I tried it with process.getprocessbyname ("myApplication") , dunno whether I was on a godd trail, or is there a far easyer way, even for activating windows without the processID.

When you click a button, the program should start op everytime your computer starts, but it must be in the background, so that you wont notice it.

1) Is it possible to allow a vb 2008 program to run at computer startup. Meaning, one the computer is turned on, it will load up with all the other startup programs so that it is ready to use.
2) I also would like to know if it is possible to have the program minimize down to the tray where all start up programs usually appear. So that instead of it cluttering up the task bar it will be in the tray and when they clcik or double click it, it will open back up.
