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 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?

I have developed a program, which will be installed by several users. How can I protect it, so, once installed, the users can use them on the installed pc, but not others. before, what I did is: create a web service, when the user use it, they need verify the account by the web service. however, it needs the user always be online, which is not applicable to this case.
View 1 RepliesWhen my program first launches, it generates a GUID which is then saved to the registry and compared to an online database when an internet connection is detected. If it is a valid registry key, another registry value is saved stating that it is valid. Is there a way to protect these 2 registry entries from being changed?
View 6 RepliesOK, so, I made a program that locks the computer with a password, to help you protect data from other people. It's quite simple, you open the program, it shows up in full screen, "To access this computer please type in the password"....etc.
BUT, I want it to have a "Guard". To make it act like a screen saver does. That's my plan: So, you typed in the password, and close the program. And then, if you didn't move your mouse, or press a key, or you're not watching a movie, for more than 6 minutes, I want it to automatically launch the program. Until now, I've just put in Form2.Show in the Form1's (which is the password-protect program) FormClosing class. I also made the Form2 on Full Screen, and it's opacity to 0%. That's where you will move your mouse. I made all the code until now, but I need code for making it act like a screen saver.
I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I have created an excel 2003 file using visual basic 2010 express edition with access as backend. The excel is created using a select into query. I would need help to protect this excel file once it generated using visual basic 2010 so that the users cannot edit the same.
View 1 RepliesHere are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?
I am making a fake virus program as a joke and would like to know how to disable all of the keys except for the shift and enter keys.(these will exit the program)

I have a lot of keyboard keys stored in different formats. For example, "Up" may be stored as a string, as a decimal (200) or as hex (C8). I need to convert all of this different representations to strings so they can be easily understood by the user, and then back again when I save them.When I capture the key press using the KeyDown event, I can grab the decimal value from KeyEventArgs.KeyCode, which can easily be converted to hex if needed.

I've encountered another minor problem with using vs 2010...how do you assign shortcut keys? I've read you just click in the shortcut keys option then press the buttons you want to be your shortcuts- this however just acts like I'm pressing the shortcut keys for vs. for instance alt x, which I want to be exit, takes me to debug. Typing alt + x in manually gives me an error saying what I've put in is invalid.
