If you mean that you want to write a service in C# there are many articles around to help you.

This makes no sense; please clarify.

Google finds lots of articles on this, including one here[^] on CodeProject.

You can use other installers for your service. I use Wix for mine.

For error codes look here[^] and work your way through the links.
As for the different types of exceptions that can be thrown start here[^] and here[^] and as you work through the MSDN site you should be able to find more.

Get ALL Error Type in C#?
where in msdn?

I gave you three links to use as starting points, the first gives links to ALL system error codes and the other two give information on Runtime Exceptions and the other on Derived Classes of System.Exception show some initiative and look through the links I provided as well as searching the MSDN site for yourself.

There's probably more than 10,000 error messages possible in the .NET Framework. There is no method that will give you a list of all of those messages.

Hi!
I have an interesting problem. I have an application that contains two textboxes. The user enters his StartTime in one textbox and his EndTime in the other.
I have a calculation method that calculated the total Hours between these two variables. The problem I am having is that when the user inserts the starttime say 8:00 and finish time say 7:00 you will get a -1 hour.
How can I prevent users from entering negative values??
My method looks like this:
private void CalculateHoursWorked()
{
string startTime = Convert.ToDateTime(txtStartTime.Text).ToShortTimeString();
DateTime startDate = Convert.ToDateTime(startTime);
string endTime = Convert.ToDateTime(txtEndTime.Text).ToShortTimeString();
DateTime endDate = Convert.ToDateTime(endTime);
TimeSpan ts = endDate.Subtract(startDate);
HoursWorked = ts.Hours.ToString();
MinutesWorked = ts.Minutes.ToString();
}

First: you should use dateTimePicker(s) instead of text boxes
(a masked textBox could do the job but => more work)
As for negative result create a function to swap dates. Something like:
private void SwapDates(){
if(start.CompareTo(end)<0)
{
DateTime tmp = start;
start=end;
end=tmp;
}
}

You should check if the time is negative. If so show an error that clearly explains that negative time is not allowed and why the time the user entererd was negative. Then highlight one of the times in red

I am very new to C# I have taken two classes on Java. But they were not the best classes. I am wanting to learn as much as I can about linking up Access Databases to Combo boxes in C#. I am wanting to create a database that I can select an item using a combo box then * a number input in a different text box and have it display in a different text box.
So for instance I would select in the combo box a food name. Then in my 1st text box I would put a number this would then * buy number of calories that is linked to the food name. And display the results in the last text box.
food Q total
Any suggestion on this or links that would give visual examples of how to get this to work?

What are you trying to say using * instead of words? In this context, * means a placeholder to select all records, or to multiply two numbers. Neither has much value in describing what you're trying to accomplish. Please elaborate.

When I used * I mean multiply. Sorry about that.

If you have taken Java classes, why are you trying to write code in C#?

The reply is not really relevant to my question. But since you seem to be interested I want to learn this language.

I am able now to get my data from the column in my database that I want into my combo box. However I want one thing to display in the combo box and when that item is selected I would like the value from a different column but same row to show up in a text box. I can get this to work sometimes I just don't understand how it is working. I am using data binding and I would like a tutorial that walks me through how this works.
Now that I have my combo box displaying the data I want from my database and that I have my text box displaying the correct data from my database when an item is selected in the combo box. I would like to take the number showing in my text box and multiply it by a number I input in a text box I will call "quantity". Then have the calculation show up in a separate text box called "total".
Do you have any advice on this or examples?

The combobox shows the selection now, if I understand you correctly, so you are able to access the data you wanted. And if I recall, you have an associated value of calories displayed in the textbox. Is that correct? Now you want to enter a quantity of the item in another box, multiply them, and display the total calories. Have I got that right?
Since a textbox only holds text data, the first thing you'll need to do is cast their contents to numeric values:
Int32 Cals = System.Convert.ToInt32(txtCals.Text);<br />
Int32 Qty = System.Convert.ToInt32(txtQuantity.Text);
Then you need to perform the calculation and convert the result to text to store it in the result textbox:
txtResult.Text = System.Convert.ToString(Cals * Qty);
I make no guarantees, since I'm new to C# and .Net, but I believe this will get you on your way again. Let me get a few chapters ahead of you and I might be able to help with the database part.

That is right I will give this a try thanks. Do you know of any good C# help sites that might have videos or code examples?

As a matter of fact, I do! You're already a member.
Spend a bunch of time in the Articles section here; there's a lot of excellent code examples, many with clear, informative explanations. I haven't seen any better resource.
