View 7 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.

I can print the current page number with the use of a static variable. How do I find out the total number of pages? Is there any particular variable in which this number is saved and can be replaced automatically later on just before printing commences by some internal procedure?
View 2 RepliesI'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

Ive 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
I dont know how to get the program to do the total calculation after i delete an item from the listbox. Basically i have 2 forms. One is the shopping item list and the other is the shopping cart.

I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part:
Ignore the second if I was desperate xD
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code].....
And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?

View 2 RepliesI am trying to add up numbers in a listbox.I know how to add them up and make them display on a messagebox but what I cant do is add the numbers in one listbox and then add the numbers in another listbox and subtract the total of the numbers from 2nd listbox from the total of the 1st BUT instead of displaying them on a message box how would I output those results into a label?This is the code I have for outputting the totals of a listbox onto a message box:
------------
Dim intTotal As Integer = 0 'Running
Dim intX As Integer = 0 ' Index Position
For intX = 0 To lstDebitsBalance.Items.Count - 1

btw the name of the second listbox I want to sum up is lstCreditsBalance
I am trying to create a textbox that will display the total duration of all video files in a listbox. I am not using the windows media player in the project, I just want to show total duration of the listbox items. I have tried looking for snippets because I'm new to programming and I have also tried my luck at creating a class with no success. If anyone could show me some sample code or tell me what it will take to accomplish my goal it would be greatly apperciated. I am coding with Visual Basic 2010 express.
View 1 Repliesas seen in picture I have in "TextBox1" some numbers and I would like to have a detailed information on "TextBox2" (marked with red) when I pressed the "Process" button about them. In other words, I want the application to tell me how many numbers in total are inside "TextBox 1" and also to tell me if there are some duplicated numbers if it finds some of course?

View 6 RepliesThe 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.
