VS 2010 Wage Calculator Error For New VB2010 Student?
Dec 21, 2010
I'm having an issue trying to get a wage calculator to recognize an overtime formula. The calculator has to have the overall function of figuring the gross pay, Federal Tax Withheld (15%), and the net pay based on the hourly wage and hours worked for the week. The issue I am having is the wage * 1.5 entry (underlined) where it sates it is not an array or a method and cannot have an argument list. If anyone can take a look at this for me and guide me as to why this error keeps coming up and what I can do to make sure it doesn

I have created a class called Student, with five private variables: [code] My main form is divided into a number of different sub procedures. In one of them, I used a streamreader to take the first name, last name, and phone numbers of a list of records in a text file called PersonalInfo.txt. It seems to work just fine. [code] I have another, separate sub procedure in which I read a different text file containing the "averages" for the students. The first average from Averages.txt belongs with the first student in PersonalInfo.txt. The second average goes with the second student.. How do I add the student average information to the properties of the student records created in the previous sub procedure? [code] I realize why this wouldn't work, but I can't figure out how I could use my counter to reference a specific student.

I am writing an app in VB2010. My code parses a text file, assigns data to variables My??, and then attempts to store this data in an access 2010 (actually access 2007 format) table. Yet, whenever my code gets to MyRow.Item("Artist") = MyArtist I get an error 5 'Artist' does not belong to Table MyTable, but the field/column does exist in the table as do all the others.
01Dim tbl As DataTable = New DataTable(MyTable)
02tbl.Rows.Add()
03Dim lastRow As Integer = tbl.Rows.Count - 1

I have written the below code for a payroll calculator. When I run the program, it gives me my own error message box no matter if my number of hours fall within the 5-60 hours range as I have stipulated. Is there something wrong with my code? (well, obviously there is something wrong--I just cant find it!)
CODE:
'This program calculates the Gross and Net Pay as well as the Tax Deduction amount of an employee's wages when given the input of Employee Name, Tax Rate, Hours Worked, and Hourly Pay Rate.

I'm basically trying to do a small report card project. I only need to pull 5 Students with each student having 5 Test Scores a piece. The full Code of what I have for the submit button is below. I have actually 3 questions.
1. I always seem to have trouble with them unless I initialize them when I dim them. Is there a better way than below
2. The below code works really well for Student 1 and all 5 test scores. Rather than do that code 5 times though, what is the best way for me to basically state that IF dblStudent1(intMax) = 4 Then Change dblStudent1(intMax) to dblStudent2(intMax) etc.
3. Would this be better suited towards a multidimensional array ?
Private Sub btnEnterGrades_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterGrades.Click
Dim strStudentNames() As String = {" ", " ", " ", " ", " "} ' Holds the 5 Students Names
Dim intMax As Integer = (4) ' Place Holder for Student Number

I am working on a mortgage payment calculator that has three user input textboxes (amount, interest, term). The interest input is a MaskedTextBox masked to (00.0). The issue I have is that if the MaskedTextBox is has no user input when the calculate button is selected then I get the error "FormatException was not handled" "Input string was not in the correct format", I highlighted the section in the code below. I'm quite positive the error stems from the MasketTextBox mask of 00.0, the decimal I believe causes the issue when no other data is entered.

I can't get the loop to work. The calculator is suppose to show how far someone goes for each hour increment (i.e. if they punch in 3 hours, it should show a number for 1 hour, 2 hours and 3 hours; if they punch in 10 hours it should show a number for 1 hour, 2 hours, 3 hours....etc. up to ten hours, etc.) I can't get it to show anything except for the total number of hours traveled and total distance.

I'm doing a simple calculator program calculating Pennies, Nickels, Dimes and Quarters. I made a Try-Catch statement so that if the user enters letters into the text boxes, they get an error message. However, if the user leaves one field blank, the error message still pops up. What's the code so that I can get Visual Basic to recognize that an empty field is the same as 0 so that that message doesn't pop up? [Code]. What do I need to add to it to get that Error Message to stop showing when the user doesn't enter a value into one of the text boxes?

I'm new in the programming area and I'm having trouble making a calculator. My question is: How do I make the calculator work using only the keyboard, without the need of mouse.
I tried this:

Me.KeyPreview = True
End Sub
Private Sub FlowLayoutPanel1_KeyDown(ByVal sender As Object, ByVal e
As System.Windows.Forms.KeyEventArgs) Handles RESULTADO.KeyDown

It only works on the text box called Result. I want to know how do I make work in the whole Class, and if it is possible, to make it work on two different Classes without writing twice the same code.

I want to make a game statistics calculator. For this I choose to make a XML database with the base stats of the characters.
I've made a small XML file in the VS2010 project with 1 class stats and made a list to 10 levels (to lazy atm to write all 85).
the XML looks like this:
<BASIC_CHARACTER_STATS>
<Levels>
<level id="1">1</level>
[Code]....
On the Form1.vb I've to combo boxes, 1 to display class names and 1 for levels.
Also have some Labels to display i.e. the base_STR number. But after trying random stuff to get it linked and closed VB to restart again because it was messed up too much
