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

how to get running total(adding numbers).
View 1 RepliesHad 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'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 maintaining a Accounting program.. I have a Cash Book Table in SQLserver Databse...field are DATE DESCRIPTION DR CR RT(Running Total is empty record). When in Insert a transaction into that Table the Running Total should give the correct balance for example :

1/1/2011 Cash Balance 5000 5000
1/1/2011 Purchase 2000 3000

I have managed a listbox with two columns (the items and their quantities). I am trying to sum up all the qtys together for a grand total, but cannot manage. I tried with listviewitem.contains and listviewitem. items. Now I'm lost.
View 3 RepliesIve got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.
Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.
I thought of two ways to do this, but I don't have a clue on what to do.
1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..
[CODE]...........
But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.
2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.
Here's a quick flow on what im trying to accomplish to make things.
Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
