LOL! 5 - but I think it went "whooosh" with the OP.

Does anyone know how to determine 'dirty' state of a Castle ActiveRecord?
If I have an ActiveRecord class called Note, and I have a List<note>, how to I determine which notes have been changed?

Hello All --
I am trying to watch a folder for any changes to it. I am integrating my code with a CAD application to make modifications to a model depending on the changes occuring in the watched folder. So, to watch a folder I make use of filesystemwatcher. But when I do that, there are some problems occuring with CAD Application. Without filesystemwatcher this works perfectly fine. Now I use timer to see any changes in that folder. Searching over the net, many told that there are some bugs in filesystemwatcher. Does anybody have the code that is behind FileSystemWatcher ?
Thanks,
Thomas.

How is the FileSystemWatching affecting the application? Unless you are modifying the files in some way there should be no issues, it simply notifies you of a change.

Hi,
I'm not aware of any bugs in FileSystemWatcher class. There are a few things you may need to know about it though:
- one file operation may result in several FSW chanes being triggered; e.g. a big write may touch several sectors and clusters; more info is here: FileSystemWatcher - Pure Chaos (Part 1 of 2)[^]
- there is no "file operation done" signal; so if your app needs to read a newly written file, a simple write event isn't sufficient. A common solution is to use another (small) file as a signal: watch for file B being created; create big file A; when done create small file B causing a signal.

Be aware that some applications strangely create an empty file first, and a few moments later on they open it for writing and write the contents. FileSystemWatcher is very fast, and you may happen to move the file away when it is still empty - if the other application then tries to open it for writing, that application could be stupid enough to cause an exception. Try to create your own watcher class by encapsulating FileSystemWatcher and dealing with empty files and files still being written by the other application, and some more strange things specific of that CAD application.

I thank everybody for dropping in and letting me know the various aspects. I still couldnt figure out why the trouble is happening. I can successfully watch a folder and get the file changed/created/deleted notifications, but when I try opening a file in UG(Unigraphics CAD App) (The next line in code is opening a file in a CAD Application) it throws out an error "Attempt to read or write protected memory." Hence I am forced to use timer. But timer is not a true solution. Probably I can send in the code and a small file to be opened in CAD, but I am dubious, whether somebody will have the CAD App.
Code : C#
CAD APP: UG NX 5
Thanks and Cheers
Thomas

hi
how can i replace "\\" with "\".
because i am using,
String.Replace("\\","\");
but it does not work.
thanx
|
|
|
|
|
That is because C# reads a '\' character as a special saying "The next character is a character to replace with something".
use
String.Replace ("\\\\", "\\");or
String.Replace(@"\\", @"\");

Normally, you don't need to:
Console.WriteLine("\\");
will output \. You have to do extra work to switch the escaping functionality off (using @ before the string):
Console.WriteLine(@"\\");
will output \\. If you are still having problems, please post extra code so we can see what is going on better.

thanks, but this is not work

The code I added does work, I checked it, and it is part of the language specification!
If you want to output \ you need to use "\\" or @"\"
If you want to output \\ you need to use "\\\\" or @"\\"
The @ character switches the escaping off. If you are still having problems, I suggest you post more of your code, something else might be happening!

Is that your actual code?
working example...
string s = @"some\\text";
s = s.Replace(@"\\", @"\");

Actually i am using xml file. In my xml file contains following text:
\u092A\u094B\u0937\u093E\u0939\u093E\u0930
and i want to convert in correspponding letter through httpUtility.htmlEncode().
when i put above code in htmlEncode function, it works properly.
when i retrieve this in C# as string it shows like:
\\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930. so this is not convert.
please guide me.

If you are simply looking at the value in the debugger, then those extra back-slashes aren't really there, don't worry about them.

i WANT TO RETRIEVE EQUIVALENT VALUE OF THE GIVEN STRING.
THE ABOVE CODE VALUE IN SEE IN HINDI IS "POSHAHAR".

And ears......
It turns out the code I posted demonstrating the difference between
Console.WriteLine("\\");
Console.WriteLine(@"\\");
doesn't work. There goes ~10 years of .net experience perhaps I should go back to asking people to switch it off and on again for a living

that is not informative at all. if you want a good answer, then provide quality information to begin with. Don't say "it does not work", specify what kind of problem there is (compilation error, run-time error, ...) and be specific (error number, exception message, line number, etc).

this is my string: \u092A\u094B\u0937\u093E\u0939\u093E\u0930
i used this code:
string unicodeString = HttpUtility.HtmlEncode("\u092A\u094B\u0937\u093E\u0939\u093E\u0930");
MessageBox.Show(unicodeString);
it gives me answer correct as "POSHAHAR" IN HINDI FONT.
BUT if we use above text as string it gives
string unicodeString = HttpUtility.HtmlEncode(above_code);
MessageBox.Show(unicodeString);
the string takes value in this form: "\\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930";
so, it can't work.
then my problem is , how am i replace "\\" instead of "\".

It is not as you said: in C# each string is unicode and something like "\u092A" is an escape sequence that mean "the unicode character with the code 0x092A. In other words, it is not a sequence of characters, but a single one.
