I'm new to forums as well as new to VB 2008. I'm in process of making a order calculator which will total any values you selected in combo boxes/checkboxes and then display it in a selected area. There are 3 things that I want to achieve: 1. Be able to add another total to an existing total (currently I'm able to see only one total when I hit "Calculate" button)2. Display how many orders I have made so far (new total counts as one order)3. Be able to add up checkboxes selected to an overall total. (when I try to add up one checkbox with another it seems to be stuck on 1.5 pounds which I assigned for each "side order")
View 4 RepliesI have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.
View 9 RepliesI need my program to output and input a customer ID and sales amount multiple times. I need it to display both outputs, customer ID and sales amount, on mulltiple lines. It also will need to accumulate the sales amount and then display the total sales. it should look something like that.[code...]
I think that I was supposed to use a messagebox but wrote the program a different way. the form.vb was already locked, but I added two text boxs. Not sure if I did this right because I need to enter multiple sales for one customer ID.[code...]
Im having a bit of trouble with my program. I have a few items that are selected by checkbox to add to a Textbox but the problem Im having is if I dont uncheck the textbox the checkboxes just make the total keep adding up. So if I have an item selected and I want to add another one by clicking its checkbox it adds the other ones to the total again and thats not what I want to do.
Dim num1 As Integer = 100
Dim num2 As Integer = 500
Dim num3 As Integer = 200
Dim num4 As Integer = 80

every time i select an item from the listbox (just 1 at a time), it'll add that item's price to the total. but for some reason it's not doing it. can someone check out my code and see what's wrong with it? i'm getting the item price as the total (what I want it to do is add onto the total)

My program takes a checkboxed item and depending on the serial number that is present on the item on the invoice, subtracts one from the amount list I have the following in a listview on a details page which I added with the following
[Code]...
Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2. if that makes sense.
the code to use to add an accumulator so I can total up the items in my shopping cart?

so i need to make a program that adds the values between 1-100 to total up to 5050 but with that being said im not sure how i would code that. since its supposed to add all the numbers from 1-100 like 1 + 2+3+4+5+6+7+8+9+10= 55 and im supposed to make the program do that until 100
View 33 RepliesI'm having some major issues with this little booger. I will supply what I've tried, but let me explain what it should do first.
Upon the text change event, if the item number is found in the DB, it should add it to the list. Then, take the 7th sub item, and place it on a label. Each time a new item is added, the cost's should add together to give me a total. Simple enough right ?
CODE:
This is a huge mess, I'm very tired and not real sure how to do it. But the item is adding twice for some reason, sometimes after I've added it one time (appears twice) and add it again, it might add 4 times, or 5. And when two items are in there, the cost displayed on lblPrice is 4x as much as it should be. Can anyone point out where I'm all screwed up, and maybe suggest a different way to go about it ?
The first would be, how would I go about making each index in a list box an integer or decimal value? For example, If I wanted the 1st (or 0) index to = 300 and the next one (1) = 400. The next question that I have is that, if I had two or more list boxes with each index as a certain value as listed above, how would I go about adding up the total for each index that is selected?

View 3 RepliesI have a sql SELECT statement in vb.net. I have this line of code to calculate a specific percentage of the Net Total:ROUND(Invoices.NetT*'" + txtOnGoing.Text + "'/100,2) As Commission 'txtOnGoing is a text box which pre populates a certain number e.g '10'... this means 10% of the NetT column..The above code works fine, now I want to add the "Commission" Column and display the Total in a text box. Does anyone know how to do this? I know I can use the SUM operator but because the Commission column isnt a column that actually exists in the table I dont know how I could do this.

I have a datagridview on a form and what I need to do is loop through the dgv and get a total of how many X's are in each individual column and then display the total in a Label. Here is the form and some information. I know how to get the sum of numbers in a column but not how to do this.
There are 28 columns Column Names are Day1, Day2, Day3 etc (so I know to use a for loop but can't figure it out) The total needs to go in the label at the bottom of each column,again they are Label28, Label29, Label30 right on up to Label56. I will continue working on it

I learned about this query 2 days ago:-
SELECT SUM(DTotal) AS Monthly FROM bdailytotal
but how I'm going to view the total value of the summation? I had been searching for this but most of the answers I get is for PHP. Can someone show me how to assign that total value to a variable in VB.NET?
Or teach me how to assign that total value to another table.
