Sentinel Controlled Do While Loop?
Oct 20, 2009
I have an issue with my DO While loop (it has to be a DO While loop). It is supposed to loop until a value of -99999 is entered for the value of previousReadiing. The program works, and it will stop after -99999 is entered, but only after it goes through the rest of the loop.How do I get this to end rather than have to finish through the other input statements and calculating again?This is homework so I don't want the answer, but can I get a nudge in the right direction please?

Here is the problem I am working on. It asks me to use the method CalculateCharges, but I don't fully understand how to do this or how it works. I would be grateful for any input.
Lab Problem III
A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours.
The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Develop a console program that calculate and displays the charges for each customer who parked a car in this garage yesterday.
You should input hours parked for each customer. The program should display the charge for the current customer. The program should use the method CalculateCharges to determine the charge for each customer.
The program should input as Double the hours parked by each customer. The program should continue asking for new customer until sentinel value is entered for hours parked.

I would like to show a form... example: Form13.Show()However, I would like to have the Opacity of the form controlled by the user and I am having trouble figuring out the coding. Ideally I will have a track bar to choose the level of opacity and a "Show" button for the user to click. But I am trying to tackle one issue at a time. I am using VB 2008 Express edition if it makes a difference.

I'm rather new to programming in general, but I have written a rather useful program for the company I work for. What I am trying to do is control the way a dialog box is displayed. I want a dialog box to pop up at certain times like 7:00 PM, 8:00 PM, etc.

Both combos load fine by do not intereact with eachothers meaning combo1 doen't filter out combo2's information.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I have written a function that gets the alexa ranking of a given url, now this function works perfectly but I want to loop through a ListView of urls and grab the alexa rank of each item (url) with my function.The code works great if I put a MessageBox in the loop to test that the function is returning a value but when I remove the MessageBox the loop does not work.I need it to loop through adding each result without a MessageBox stop in each loop.
vb
For Each Item In ListView1.Items
Dim result As Integer
result = GetAlexaRank(Item.Text)

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

I'm slowly learning about loops. I have a couple of questions
1) When a condition is being tested.. what does that mean? I don't understand the "condition" word.
2) What is the difference between a loop that never ends and a loop that ends?
I have the code for the loop that ends and the loop that never ends. I can see the difference in the code, but I don't understand what is making it different. Here is the code below.
