I am a C# programmer with about 4 years development experience. I currently busy with an Equipment Management System. I want to add a Vehicle Tracking feature on the system. I have done a couple of searches on the net, but the results I get are not specific.
Can anyone plz tell me what Hardware and software I need to use GPS on my windows application.I would most propably appreciate a list of all hardware and software necessary for my application to work, and possibly a step-by-step guidelines.
Programming is not a skill, it's an art.

Book are generally used to hide information in, especially the kind of book you are talking about. So the answers are in the book, not somewhere else.

Your question makes totally no sense. It also beggars belief. Without telling us what the book is, what can we possibly tell you about it ?
If the book has questions and no answers, it's kind of useless. If it has source code listings and you want to download them, do a google.

I'd give a 95% chance that the questions are designed to make you think about the chapter you read, and the answers are not listed because it's assumed you know them, because they are in the pages you just read.

very thanks for your reply but can u help me to answer some questions like that . or give me the idea
Create class SavingsAccount. Use static variable annualInterestRate to store the interest rate for all account holders. Each object of the class contains a
private instance variable savingsBalance indicating the amount the saver currently has on deposit. Provide method CalculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should be added to savingsBalance. Provide a static method ModifyInterestRate that sets the annualInterestRate to a new value. Write a driver program to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest and print the new balances for each of the savers. Then set the annualInterestRate to 5% and calculate the next month’s interest and print the new balances for each of the savers.

What is the book ? Can you do NONE of this ? If so, I suggest either the book is useless, or programming is just not for you.

Is there a method in the .NET framework that I can call to get the window with the current focus. All I've been able to find on the net is this:
// Return the handle of the window that has the focus.
[DllImport("user32.dll")]
public static extern IntPtr GetFocus();
This isn't built into System.Window.Forms?

No, it is, by definition a PInvoke call to load a function out of user32.dll and call it.

Yeah, I just think it's strange that it's not built into the framework. Wonder what their reasoning was...

Hi,
Being relatively new to C#/.Net I am having problems finding a simple solution to the following scenario:
I have a table with many fields including FirstName, LastName, MemberID and EmailAddress. I need to display a checkedlistbox with all the FirstName + LastName's BUT I need to only pass the relative selected EmailAddress to another table. I don't want to show the EmailAddress in the checkedlistbox.
I can populate the listbox as well as retrieve the selections without problem but is there a way to "hide" the EmailAddress in the checkedlistbox but retrieve it when selected?
Thanks,
Glen Harvy

A listbox item has .Tag right? If so, store the e-mail address in the tag, item.Tag = "mmmm@bacon.com";
You can store pretty much anything in the tag, so when your populating the list, just put it in the tag for that item.
|

|

Thanks for that - I've used the tag for this purpose before but forgot it.
It doesn't seem possible however to ".Add.Tag" so I will need to bind the listbox to a dataset which is what I didn't want to do <sigh>.

Try this when your adding an item:
ListViewItem item = new ListViewItem(stuff);
item.Tag = whatever

Hi,
I made a calculator which calculates measurements. The application asks you for example "how much is 200 centimeters in meters".
Because these calculations could have broken numbers i am forced to use doubles.
But when i type the answer, it keeps saying its wrong.
Suppose an answer is 0,0009. But when i look in the array which holds all the answers i see 0,0009000000000000012.
How can i solve this?
Thanks in advance!

"Double" stores values in base-2 representation. Like you cannot exactly represented 1/3 in decimal notation, you cannot represent 1/10 in base-2 representation. That means you always have rounding errors when using double.
Never compare two floating point numbers for equality, but instead consider two numbers to be equal if Math.Abs(value1 - value2) < 0.00000000001.
Alternatively, you might use the type "decimal" which stores numbers in base-10 representation.

Hi,
Thank you very much guys!
Didn't know there was an alternative type for double except for float.
But decimal did the trick!

I like to create (or download) a program that can let the user open several PDFs and print those on an installed printer. I don’t have to preview the PDFs.
If I have 5 documents and like to print 10 copies of those, the program should send 50 printing jobs to the printer.

How can we convert a byte array to stream or stream to array of byte? So How can we change the size of stream? Can we change the stream lenght(or size) bigger?
I thank you very much for your answers.
