You can effectively think of .NET 3 as a service pack, in that it builds on .NET 2. This means that Vista comes with .NET 2 by dint of the fact that .NET 3 is installed.

Hey all,
I currently developing an application where i need to "keep an eye" on certain files on any given folder...
I am doing the following:
System.IO.FileSystemWatcher watcher = new System.IO.FileSystemWatcher();
watcher.Path = @path;
watcher.NotifyFilter = System.IO.NotifyFilters.CreationTime;
watcher.IncludeSubdirectories = true;
watcher.Filter = ".txt";
watcher.EnableRaisingEvents = true;
watcher.Created+=new System.IO.FileSystemEventHandler(watcher_Created);
watcher.Deleted +=new System.IO.FileSystemEventHandler(watcher_Deleted);
// the events handlers
watcher_Created(object sender, System.IO.FileSystemEventArgs e)
{
MessageBox.Show("File Created: "+ e.Name);
System.IO.File.Delete(e.FullPath);
}
watcher_Deleted(object sender, System.IO.FileSystemEventArgs e)
{
MessageBox.Show("File Deleted: "+ e.Name);
}
However it seems that i am missing something here because I am creating a file in the given path but the events are not been triggered... What am i missing?
Oh, i would also i like to know if a file is renamed how can i changed it back and if it is deleted how can i restore it?
Thanks all!

You are missing in this line. your are notifying only the Creation time, but not file name !!! 
Try this one
mywatcher.NotifyFilter = NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.FileName | NotifyFilters.LastAccess ;
This will work.. and let me know when done !!!!
Good luck

Thanks for replying but it seems that i am doing something terribly wrong because it is not working yet and to make sure i modified the notifier like this:
watcher.NotifyFilter = System.IO.NotifyFilters.CreationTime | System.IO.NotifyFilters.FileName |
System.IO.NotifyFilters.Attributes | System.IO.NotifyFilters.Size | System.IO.NotifyFilters.Security|
System.IO.NotifyFilters.LastAccess | System.IO.NotifyFilters.LastWrite;
but no luck yet, maybe i need to add something else?
What do you think?

I found what i was doing wrong .... on my desperation to get it to work i added: Watcher.BeginInit() when the form loaded, but once i removed that line it worked well... now any tip on how to restore it the files to what they were before any changes were made... like if renamed restore the file and if delete it restore it as well...
I think a better question would be how can i backup an entire folder or how to store these files into a database without causing perfomance issues?

I have the code to retrieve a list of files/folders from an ftp-site and I have the code to extract an icon from a local file but can I get the icon from a file on an ftp-server?
Is there a way to get the standard icon used by the local system for say ".rar"-files without actually having the file?

You'll have to use p/invoke for this. The corresponding win32 function is SHGetFileInfo[^].
You don't need an actual file, a file name alone will do.

Hello,
I'm new in C# programming and I have a question.
I want to delete a row from a table using a button.
The row i want to delete must have the same information that the selected cell in a grid view.
How can i do that?
Thanks.
|
|
|
|
|
All you need is a stored procedure that takes as a parameter the ID of the row you wish to delete. Obtain the ID from the selected row in the grid.
only two letters away from being an asset
|
|
|
|
|
write CommandText = "delete from <tablename> where <row identity=""> = " + >gridview selected item<
hope it will help

Hi All,
Slim pickings for this topic on MSDN [1, 2]. [2] does not really apply, but it was a keyword hit ("SelectedItemChanged"). Does any one know how to receive this notification? I'm not receiving it.
What I done so far: Hightlight the TreeView in Design Mode, and then switching to Events: no SelectedItemChanged available. I tried the following (TreeView control name is ObjectTree):
private void ObjectTree_SelectedItemChanged(object sender, EventArgs e)
{
...
}Sorry about another beginner question. I have no idea what to do with (from [1]):
public static readonly RoutedEvent SelectedItemChangedEvent Pasting it into the code resulted in compile errors. The Microsoft Wiki[^] is looking more appealing every day.

Hi Jeff,
I don't know, I haven't had much experience with TreeView, but I noticed your [1] ref is
on .NET 3.0 suggesting SelectedItemChangedEvent does not exist on 2.0 (assuming that's
what you use), which confuses me since 3.0 is said to be identical to 2.0 except for
extra modules (WPF, WCF, ...).
RoutedEvent is unknown to me; it too requires .NET 3.0

Huh? A rainbow...
So it starts off really hard, then eases out. And as time goes by you slowly forget everything you already learned?
My current favourite word is: PIE!
Good ol' pie, it's been a while.

Yep. It invites you for a long journey, but you will never reach the end (remember,
that's where the pot of waffles and pie is). I can't remember the part about forgetting
everything though.
