Adding Total On TextChange Event
Sep 30, 2011
I'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 ?

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")

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)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim total, grandtotal As Decimal
If lbSelect.SelectedIndex = 0 Then
total = 10

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?

I have four forms only. The first one is the main menu, that contains three buttons, the first and second buttons go to form2 and form3;Button 3 should open a new form (4) and to write there just the total price.
In Form2: DataGrideView that contains a table made by MS Access 2007. That table contains only two columns and three rows. When you select the item, the price of that item should be saved to be added to the other selected items
In Form3: ComboBox that contains another table also made by Access2007. The same thing, the table contains two columns and the selected item has a price that should be summed with the first selection in Form2.
My Questions are:
1. What I did by adding data from MSAccess2007, is it right?First: View -> server explorer -> Browse(my database) -> Test Connection --> OK ...Second: Data Sources --> Add new database --> etc Third: I dragged one table and put it inside Form2, then the another table to Form3.Is that all right? <--- This is my first question.
2. Now, is, what I have done in step 1, enough to pick up the price of the selected item(s)?if not, what is the code that I have to write to make this connection, and where?
3. As I said, when I click on Button3 in Form1, Form4 should appear and give me the grand total. How I can write a code that makes this summation, and where?

I have a class project that I have been working on for a while, and I can't figure out how to add each cost from lstCosts together to show a total cost of the selected workshops in lblTotalCost. Using the current loop that I have, it only adds the last cost in lstCosts. Is there a way to add the indexes together?
Code:
Public Class Form1
' The registration fee for each workshop
Const intSTRESS As Integer = 595 ' handling stress
Const intMANAGEMENT As Integer = 695 ' time management
Const intSKILLS As Integer = 995 ' supervision skills

I'm trying to display the total extraction progress of a zip file as below. This gives me the total file size of all uncompressed files in the zip:
For Each backup In zip
TotalSize = backup.UncompressedSize + TotalSize
Next
I'm then using this to get the current bytes transfered:
TranferTotal = e.BytesTransferred + TranferTotal
The problem is this value resets after each file is extracted from the zip. I was expecting the above to "tally up" the total so I could use it for the progress bar but it seems to still reset after each item? Also, I'm using a global varible for the transfer total, if there a better method to transfer this information to the StepEntryProgress? The reason I'm doing this is because the DotNetZip Library does not support multiple extraction in this way, so I need to tally up in this way.
Code:
Imports Ionic.Zip
Imports System.Threading
Imports System.ComponentModel
Public Class Form1
Dim TotalSize = 0

When I utilize AddHandler in VB to add my own method to the Click event :
AddHandler Button.Click, AddressOf myButton_Click
I see that my code executes last - after other event handlers for the Button_Click event. Is there a way to insert my event handler in front of other events so that it executes first?

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 am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.
Here is the code:
Imports Microsoft
Imports Microsoft.Win32
Imports Microsoft.Win32.Registry
Imports System.Collections

In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?

When the user clicks a cell in a new row (the row headed by the *) I am populating a column with an integer that is incremented in the "DefaultValuesNeeded" event. However, when the user clicks off the row (having done nothing to the row), what event gets fired? I need to decrement my counter but can't locate an appropriate place to do it.
