I have a serial ports list. I declared it like this:
<br />
private List<SerialPort> lstSerialPorts;<br />
<br />
for (int i = 1; i<=cont; i++)<br />
{<br />
SerialPort tempPort = new SerialPort("COM" + cont.ToString(), 2400);<br />
lstSerialPorts.Add(tempPort);<br />
lstSerialPörts[i].DataReceived += SerialDataReceivedEventHandler(TEST_FUNCTION);<br />
}<br />
My TEST_FUNCTION is empty so far:
<br />
<br />
void TEST_FUNCTION(object sender, SerialDataReceivedEventArgs e)<br />
{<br />
throw new NotImplementedException();<br />
}<br />
As you can see, all serial ports have the same handler function. How could I check which serial port triggered the TEST_FUNCTION? It would be great something like this:
<br />
void TEST_FUNCTION(object sender, SerialDataReceivedEventArgs e)<br />
{<br />
Console.WriteLine("This function was triggered by: {0}",anUnknownVariable);<br />
}<br />
Parameter "e" does not have any useful property or function
Any help would be apreciated and excuse me about my English if I made a mistake

You've looked at the e parameter - now try the other one!
The clue is in the name 'sender'. Cast it to a SerialPort from object and you now have the object that raised the event.

Use the sender object, cast it to SerialPort and you will get the object who triggered the function.

If 'e' is not a lot of use, have you considered looking at 'sender', by any chance?
If you expand it in the debugger, you may find it is a SerialPort object.

Thx a lot guys

I know your proble is solved but something I noticed in the code and wondered if it was correct.
Should new SerialPort("COM" + cont.ToString()
be new SerialPort("COM" + i.ToString()?
Good of you to thank the guys. Not everyone does.

I want my application to programatically download a file from skydrive.live.com,
but I encountered a problem:
Microsoft uses script for file download that makes it impossible to download the file using WebClient (at least as far as I know). Could somebody help to find a workaround on how to download the file?
The microsoft's script is:
Download
var $SelfPage = new function()
{
var _download = 'http\x3a\x2f\x2f5odcbq.bay.livefilestore.com\x2fy1pi19dAInfgawlhjDTcs2sbdCJEkvL7jzsz8SVx9qA-EiQwX-ZPeg-DCt63IEoNWu7USu9uUA-j9FkUosBKqU-3Q\x2fApskaita_1.1_beta_update.exe';
var _demote = 'http\x3a\x2f\x2f5odcbq.bay.livefilestore.com\x2fy1pi19dAInfgawlhjDTcs2sbdCJEkvL7jzsz8SVx9qA-EiQwX-ZPeg-DCt63IEoNWu7USu9uUA-j9FkUosBKqU-3Q\x2fApskaita_1.1_beta_update.exe';
var _dirty = false;
this.MarkDirty = function() { _dirty = true; }
this.Download = function()
{
if (_dirty)
{
_dirty = false;
window.location = _demote;
}
else
{
window.location = _download;
}
}
}

 Hi I don't know if anyone could help me. I'm beginner on C# programing and I have an assignment to finish and i don't know how to finish!!!
I started creating a program with a menu with options to creates a new file and read the new file. The files that I create have an boundary limits(not less than 125 and no more than 350 characters in number) and after creating and saving the file there is an option to go to main menu. This is the part that I've done. Now I have to after writting on the new file create an option to encript and save the file and when opening the file it should have another option to go back to plain text format(decrypt). The encryption should be represented as numbers grouped in pairs, and it should create alternate numbers(written twice). for some single letters ( the most common ones a,e,o,r,t), also using null characters I have to include some mechanism for introduce spaces!!! I really apreciate if anyone could help me with some suggestions,
Thanks

I would encrypt using built in encryption classes like Rijndael-Managed, what is it you want to do, exactly?

I'm on my first year of C# i've learnt all the basic but I don't know how to encrypt or decrypt any message, that is my biggest problem. Really I don't know how to convert characters to integers,
Thanks for your help

Probably because it's so simple:
char c = 'a' ;
int i = c ;
System.Console.WriteLine ( i ) ;
c = (char) i ;
I'd be interested in hearing more about this simple encryption process.

The Convert class is evil; don't use it.

Mostly. The only member of Convert I use is ChangeType and that only in extreme circumstances.

What do you have against it?

I'll have to check my code at some point. I could've sworn I found places where I had to use the convert class instead of casting before.

Please do.
I've found ChangeType to be useful when I don't know the destination type at compile time and even generics won't help; it's rare. One example I have is loading a DataTable from a CSV file. Otherwise, if you know the destination type, just use it.
I ran a little test and found int.Parse to be 3% quicker than Convert.ToInt32 (ToInt32 requires an additional method invocation), which isn't much, but as it supports my position I'll consider it significant.

It was string to int conversion I was thinking of, although why int foo = (int)"1" fails but int foo = (int)'1'; does not is a question I'm afraid to ask.

It gives the ASCII value (Unicode code point / whatever) of the character, which I assumed is what he wanted.

This part is not particularly clear.
Does it mean that if your scheme decides that the letter 'a' = the number 4, then it should be written as 44 "(written twice)", or does it mean something else?
Do you understand what it means? Because if not you should go back to the assignment setter for clarification. Make sure that you fully understand the problem before posting here.
You should also make some attempt at writing some code, so that you can demonstrate to people here that you are trying and not just asking someone else to write your assignment for you.
To get you started:
Research how to get a character from a string.
Research how to convert a char to an int
Good luck!
