I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I am creating a form that calculates QB Ratings but its not coming out right. The formula is found here
My code:
Dim a, b, c, d As Integer
a = (Comp.Text / Att.Text * 100 - 30) / 20
b = (Yards.Text / Att.Text - 3) * 0.25
c = Tds.Text / Att.Text * 20
d = 2.375 - (Int.Text / Att.Text * 25)
Rating.Text = "QB Rating:" & ((a + b + c + d) / 6) * 100
Number set 1:
22 complete
36 Attempt
2 touchdowns
0 Interceptions
229 yards
It should come out 98.0 but comes out 100
Number set 2:

VISUAL BASIC 2008. Program Description: Create a program that calculates the amount of quarters, dimes, nickels, and pennies are needed from an amount of change (entered in pennies). The program should use the largest coins possible (for example, fifty cents should use two quarters, not five dimes, fifty pennies, etc.)
I don't want the code already written out, I need somebody to walk me through making a code. Also, this is my first class dealing with computer programming so all we've learned so far is declaring variables and how to label objects, the simple stuff. I'm at a loss at how to start because a quarter is worth 25 but the program is supposed to show how many quarters once a user enters the amount in cents.
Create an application that calculates the total cost of a stay in a hotel in the North Carolina mountains. The application should accept the following in terms of input:Month of Check in Length of Stay (in Nights) Number of Persons Room Service Charges Phone Charges Other Charges If the check in occurs in November-March the rate is $89/night. April-August is $99/night and September-October is $109/night. $10/night should be added if more than 2 people are in the room. More than 4 people are not allowed in the room, and a traveler can only request 1 room. A 15% tax should be added to the room rate and 10% tax added to all room service and other charges. No tax will be added for phone charges.
The program should use a function to calculate the total charges for the visitor's stay and output it to a label. There should be buttons or menus to calculate the total, clear the form, and exit the application.At least one of the button should call a sub procedure which performs its function. I don't understand how to set this program up and I'm not sure what it means.

[URL]...The link above is a thread showing the application I'm working on. (2008 Pro)I have since created an MDI Parent form which holds my 16 camera forms. What I am having trouble with is dividing the MDIParent's Width and Height by 4, to display 4 equal height/width camera forms within it.
I've tried all the available properties (Rectangle, ClientArea, etc) and none seem to calculate correctly.Using Me.Width and Me.Height ALMOST worked, but again, it was about an inch too skinny and short.
What do I need to do in order to retrieve the exact size of the MDIParent's Client Area?
I am building a program that calculates the number of books by points.Ex: 1-3 books read are worth 10 points, 4-6 are worth 15 and > 6 are worth 20. The issue I'm having is getting it to calculate the the first 3 books, the 2nd 3 books and then the > 6.Ex: User inputs 8 books read. It should display 115 in the label.
1. I'm using an If statement (should I be)
2. Could I use a decimal for the > 6?
Ex: intTotalNumberOfBooks = (intTotalNumberOfBooks * intFirst3Books) *#D

I am working in Visual Basic 2008 and am trying to create an application that calculates body mass index. I have the entire form complete as well as much of the source code, but I am having trouble creating the code for input validation. On the form I have a text box for entering weight and a text box for entering height, which are both used to calculate the body mass index. Therefore, both text boxes input information cannot be negative or an illegal character ( $, @, !...) The input validation is supposed to present a Message Box that displays something along the lines of "Please enter numeric values" when input values are illegal characters "Please enter a positive number" when input values are negative "Invalid Entry" when input values equal 0

View 1 RepliesThe hotel has 8 floors and 30 rooms on each floor. Create an application that calculates the occupancy rate for each floor, and the overall occupancy rate for the hotel. The occupancy rate is the percentage of rooms occupied, and may be calculated by dividing the number of rooms occupied by the number of rooms.When the user clicks the "Complete Report" button, a loop should execute and iterate 8 times. Each time the loop iterates, it should display an input box for one of the hotel's floors. The input box should ask the user to enter the number of rooms occupied on that floor. As the user enters a value for each floor, the loop should calculate the occupancy rate for that floor, and display the information for that floor in the list box. When the number of occupied rooms has been entered for all the floors, the application should display the total number of rooms occupied and the overall occupnacy rate of the hotel.I have some of the code but I'm not sure which way to go now!

The program is a hotel occupancy form The Hotel has eight floors and 30 rooms oneach floor. I'm supposed to create aapplication that calculates the occupancy rate for the hotel. Theoccupancy rate is the percentage of rooms occupied, and may becalculated by dividing the number of rooms occupied by the number ofrooms. For example, if 18 rooms on the first floor are occupied, the occupancyrate is: 18/30 = .6 or 60%. The form has two out labels called totalrooms occupied and overall occupancy rate that holds two output text boxes todisplay the numbers
its only three buttons Calculate report,close, and exit Its obvious what the exit buttons issupposed to do the clear button should clear all the controls on the floor
Now the complete report button is supposedto loop and iterate eight times. Each time the loop iterates, it should displaya input box for one of the hotel floor. The input box should ask the user asksthe user the user to enter the number of rooms occupied on each floor. As theuser enters a value for each floor, the loop should calculate the occupancyrate for that floor and display the information for that floor in a list box.When the number of occupied rooms has been entered for all floors theapplication should display total number of rooms occupied an overall occupancyrate for the hotel. (the hotel has a total of 240 rooms total)
