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 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.

Dim sqlx As OleDbCommand = New OleDbCommand
[Code]......
I get an error saying "No value given for one or more required parameters." when I try to run my program on this line "Dim rdr As OleDbDataReader = sqlx.ExecuteReader()"

I've got a list of System.Drawing.RectangleF objects that all overlap the same RectangleF object.In my picture below, the 3 overlapping rectangles would be the pink, yellow, and red rectangles.My main rectangle in question is the light blue rectangle.
Second Image: I know that with RectangleF objects I can use the Intersect() method that will return me another RectangleF object representing the overlap. But as far as I can tell, this only really works when comparing two rectangles.
My question is: How could I determine the TOTAL area/percentage (i.e. the combined total overlap of the red, yellow, and pink rectangles when compared to the light blue rectangle - but it would need to be smart enough to not count the area in which the red and yellow overlaps twice, and same for the pink and yellow)?
NOTE: The green lines represent the area I'm looking for, just the total area of the blue rectangle that is not visible.
UPDATE: I've added a 2nd image to further demonstrate what I'm looking for. In the second image, the presence of the burgundy rectangle should have no affect on the total percent covered because that area is already covered by the yellow and green rectangles.

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

The program is for calculating an amount of fruit. I have a label saying the name of the fruit, a textbox to enter a value of 0-99 and another textbox with ReadOnly which will show the price.
A little picture here:[URL]
As you can see, the Fruit1 Etc... Is only the fruit name.
The Text box wich indicate 1-99 means the number of fruit.
The Textbox with Cash on it, means the total price.
The Calculate button, when I will push it, all the total price from all the fruit will be added together to form a total price which will be indicated in the total price textbox under the Calculate button.
When I will enter the number of fruit, if I enter 99, it give me a price.
When I will enter 60, I want that the 60 are multiplied by (let say) 0,10$
I just like to know how I can do this... Its really bothering e and I don't want to calculate all the things and make 99 line for 1 fruit cause it will be long.
The code I was using was:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text = "99" Then
TextBox2.text = "10.00$"
Elseif TextBox1.Text = "98" Then
TextBox2.Text = "9,90$"
EndIf
End Sub
Until the the number of the fruit in the code reach 0. So its very long.

I have successfully written this interest calculation, although it is based on the ppmt function and adding up the interest from each payment. This is quite a long looping process.. And it is not accurate because of the rounding of each payment. I was wondering if someone knows if there is a formula I can use, or if the pmt function is capable of this? (e.g. Mortgage payment - total interest payable over 30 years at 5% ( principle and interest repayments))?

I have a class assignment where i have to calculate the total cost of a parking garage from hours but i have to do it with a method function. So this might be a stupid question but can you read the user input values from a textbox in the function itself or do they have to be read in and recalled from the Private Sub Button1_Click section?

Now my programm is finish and have full function, but.... it is sooo slowly with dataset/datatable/query-creater. Before I used DataContext like:
PUBLIC CLASS Main
Private db As New KontoauszugSQLDataContext
.
.
.
Privat Sub LaufendeSumme ()
[Code].....
This works much faster. May be something wrong with System or is this normal? I think it must be quicker to get a queryresult with dataset/datatable/query-creater then with the DataContext version and its update.

I want to create an application that able to calculate the total time the user (i.e. myself) spent on a particular application, for example Firefox. And this application should display warning message if the user spent a lot of time on Firefox (for example 1 hour or more)Reason: I'm a VB.NET developer. During my working hours, my main tool is Visual Studio and I suppose to do coding. But I need Firefox occasionally to access internet (particularly SO and other sites) to find solutions for my programming problems. The problem is I addicted to SO and SO sucks my time for hours until I have forgotten that I suppose to continue coding and not browsing the SO site.
