I hope he's not, as the index of the first character in a string is 0.

I don't know how that happened, I distinctly remember typing a 0.
At least I remember thinking I should type a 0, it was late, I was tired. What can I say.

One last try.
Does this:
int lineCount = 3;
string baseText = "Sending File.... ";
for (int i = 0; i < lineCount; i++)
{
textBoxConsole.AppendText(string.Format("{0} Line {1} of 3" + Environment.NewLine, baseText, i + 1));
}
do what you want? Or at least give you some ideas.

Then why do you insist on wanting to know the index position of something that does not exist.
asquaredtech wrote: My question is why the the index of the string counts the "\"s and the length does not.
It doesn't. They both operate on the same sequence of characters.
Okay, here:
string s = "Hello\r\nWorld"
s.Length == 12
s[0]=='H'
s[1]=='e'
s[2]=='l'
s[3]=='l'
s[4]=='o'
s[5]==the return character
s[6]==the newline character
s[7]=='W'
s[8]=='o'
s[9]=='r'
s[10]=='l'
s[11]=='d'
As you can see, there are 12 indexes and the string length is 12. They are the same. The indexes start at 0 (as they always do in C#)
asquaredtech wrote: All I want to do is overwrite an existing string of text with a new string of text. I have it working other than the fact that the string counts the "\"s when referring to the index of the string.
Gosh! Then lets look at your actual problem rather than go around in circles about string lengths and indexes.

Then look at the original post and answer the question instead of putting worthless comments in. You're contributing to the confusion.
I wonder if anybody has tried the sample in my original post if they are just guessing what it does.

It would be better if you posted part of the code that you are actually using, instead of posting some other code that does not quite do the same as what your actual code does.
The code that you posted does not do what you say that it does. Instead it will put the string "Sending File....\r\nLine 1 of 3Line 1 of 3Line 1 of 3Line 1 of 3" in the text box. The Remove call will not change the string at all, as it doesn't assign the result back to the Text property.
If you want to keep part of the string, use the Substring method to get that, and concatenate with the new string:
textBoxConsole.Text = "Sending File....\r\n";
int len = textBoxConsole.Text.Length;
for (int i = 1; i <= 3; i++) {
textBoxConsole.Text = textBoxConsole.Text.Substring(0, len) + "Line 1 of 3";
}

The code in the application is very similar, except that it calls methods from other files that return strings. These methods communicate with microprocessors and other peripherals. This is code I have made simple and have been debugging with the same problem, remember keep it simple?
Actually the code will put the string:
"Sending File....\rLine 1 of 3"
the remove command removes the "\n" because the text string has indexes for the "\" even though they are not counted separately in the text.Length.
I will try the code you provided, it looks like the best recommendation thus far.
Thanks.

If you want to make a simpler code to demonstrate the problem, you have to make a code that actually does demonstrate the problem. The code that you posted didn't do that.
asquaredtech wrote: Actually the code will put the string:
"Sending File....\rLine 1 of 3"
No, it wont. As I explained, if the code would have assigned the result of the Remove call to the Text property it would have produced that result, but the code doesn't do that.
asquaredtech wrote: the remove command removes the "\n" because the text string has indexes for the "\" even though they are not counted separately in the text.Length.
No, it would remove the '\n' character because you are sending the wrong index to the method. The string does not contain indexes for the escape characters used to specify the string literal.

I am a noob working a webpage, i wanna pass multiple values from a select box in a query string so that a report may be generated any one can help me please. So basically, if the user enters only one value, only 1 report is queried if they entered more than 1 then more than one report is generated one after another. this is the code i already have, it only make one query to the database now. I want the reports to be created one below the other.... and so on.

What do you mean report here?? Is it a crystal report? I dont see any report binding code.
I would appreciate if you elaborate your requirement.
Cheers,

i am cheap, can't afford crystal, lol. I wanna create a form that grabs data from a database and insert it in my layout, the problem i am having is that i want to grab multiple records from the database and display it. Three per page.

Instead create a usercontrol (which should have your forms' controls) to bind the data, and put a for loop for number of querystring items, and call the usercontrol and bind the data.
That should solve your problem.

I am used to C++ more than C#.
In C++ you have header files and you have the ability to declare states. For example, you can declare a series of unsigned integers to be for a variety of different states to later use in switch statements or if-then statements.
Since C# does not have the same sort of structure with header files, how would I impliment a simular functionality in C#?
The reason why I want to use UINT is because you can do that super cool bit-wise and and or with them. Remember those good ol' days? You could define four different conditions like this:
UINT state_001 2
UINT state_002 4
UINT state_003 8
UINT state_004 16
Then a variable can be any one state or any combination of states. To assign a variable a particular state, you do a bitwise and to the variable. To see if the variable was set to any of the states, you do a bitwise or.
How would that look like in Visual C#?

It would look good, and a lil' bit more readable than C++.

Use an enum with the [Flags] attribute set for a bitfield. Here's a snippet from MSDN:
// A bit field or flag enumeration of harvesting seasons.
[Flags]
public enum Seasons
{
None = 0,
Summer = 1,
Autumn = 2,
Winter = 4,
Spring = 8,
All = Summer | Autumn | Winter | Spring
}
Hope this helps!

Xarzu wrote: How would that look like in Visual C#?
It would look better.
You use an enum, which gives it more structure. This will also give you the possible values to use right in the intellisense, so you don't have to wade through loads of header files to find out which constants you can use.
[Flags]
public enum Feeling {
Happy = 1,
Hungry = 2,
Free = 4,
Cold = 8
}
The Flags attribute enables you to perform bitwise operations on the enum values:
Feeling xarzu = Feeling.Happy | Feeling.Hungry;
if ((xarzu & Feeling.Happy) != 0) MessageBox.Show("Xarzu is happy.");
The data type that the enum uses by default is int, as that's the most efficient type. You can specify a different type like an uint if you like, but there is rarely any reason for that.

No-one is going to read all of this, or do your homework for you. How about you tell us which line is not doing what you expect ? Have you spent some time in the debugger to see where the code is not following the logic you hoped for ?

Hi,
The Viterbi algorithm is an interesting one, IMO its working is best explained and understood using
several graphics, rather than code. Anyway it is beyond the scope of a forum like this one, you would
better look it up in a specialized book, such as a digital communications course.
Once you fully understand the allgorithm, I suggest you take a really really simple test case,
and work it out by hand, then run it through the program you want debugged, and compare the results
step by step. Don't expect too much help from this forum, unless you prove you understand and really
tried, but got stuck at a very specific point.
