Sorry, but I can't help you there - I assumed from your original post that "read-only from a users perspective" meant it did not include paste! As I have never tried to implement that you are better off getting help from someone who has.
Another option might be to look at existing Terminal emulators which it may be possible to modify to your needs (ie rip out the serial port bit) as these would include some colour control, probably via ANSI escape sequences. Never tried them, but I know they do exist in commercial and open source variants.
All those who believe in psycho kinesis, raise my hand.

Yep, no problem. Thanks for your help anyway.
Just to note: I am not actually wanting to implement paste - just select and copy (over multiple lines or only parts of lines, as with a TextBox)... sorry if the mention of paste added confusion.
As mentioned, looking at existing Terminal Emulators, I can't find anyone that's even considered this. They tend to use a standard RichTextBox and there's nothing in there to handle what happens when it flows over the character limit (I assume that if they've even thought about it, they just think it's unlikely to ever happen - with a limit of 2147483647 chars, it works out to a few months at 10 lines per second with 100 chars per line (maybe I'm just being fussy by worrying about it?) (actually, I still don't know what behaviour to expect when it overflows... if you set a MaxLength manually, it's ignored for programmatic input - it only stops manual input after that amount))
Regarding ANSI colour - I've already written all that myself. The current version of my app uses a RichTextBox (as with everything else I've seen), so it's not holding up my development work - I just want to avoid possible future problems.

Woo! No-one is going to scroll back through 2Gb of text - it would take all week!
Why not just append it to a log file and show the last 200 lines or so? Then at least you are limited by just the disk space, rather then the virtual memory and the chars in a rich text box?

Of course you're quite right noone will scroll back through that much. My plan is to limit it to approx 20000 lines though (200 is way too little for the kind of thing I'll be outputting).
Regardless, it doesn't change the need to elegantly handle dropping off the old data and displaying the new.
If I come up with an elegant solution, I'll be sure to post it here on CodeProject for others who have also spent their time looking for such a thing.

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.

What do you want to use?

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.

I wanna to get all "Exception" in C# ?

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.
