I'm trying to watch a file from my XP-Pro workstation to either a Win2000 or
a NT4 machine and everytime I try to set the path property to something such
as \\PDC1\cdrive\ I get a system.nullExce ption error.
Anyone have any ideas? Does this work? It works just fine on my local
machine: "c:\abc\def \"
Thanks. Jon Lea 6 3034
First question: Do you have permissions to that share?

Thanks for the reply. I have permission to the share: I'm able to save a
file to that share from within Word. I'm using the following code:
void FileWatcher::Se tFile(String* fullPathName)
{
FileInfo* fi = new FileInfo(fullPa thName);
m_watcher->Path = fi->DirectoryNam e;
m_watcher->EnableRaisingE vents = true;
m_watcher->Filter = fi->Name;
}
and the exact exception is:
A "System.NullRef erenceException " occured.
Object reference not set to an instance of an object.
and it occurs on this line:
m_watcher->Path = fi->DirectoryNam e;
and fi->DirectoryNam e returns \\Pdc1\cdrive\.
I was doing some searching on the net about the FileSystemWatch er and found
this link: http://msdn.microsoft.com/library/de...t4machines.asp
It sounds like FileSystemWatch er has a few problems with network file
watching.
Thanks again and let me know what you think. Jon.

Michael - I think I've solved my problem - its amazing what a day makes.
Apparently the FileInfo class drops the last "\" on network files and has it
for local drives. I added some code to make sure the last "\" is on the
directory name before asssigning it to the path property and things seem to
work now. So I can use my XP-Pro workstation to watch files on the NT4
server and also on another Win2000 workstation. I'm in the process of
testing it with a Win2000 workstation going to the NT4 server.
Thanks for the help. Jon.

I had also made some other changes in my attempt to fix things up when I
stumbled upon this so I don't know if this was the only/real culprit. A

How do I prevent the FileSystemWatcher event to keep firing while the file
is being created? When copying a file to the watched folder, the event
fires a dozen or more times! Also, the documentation states that if more
than one file is copied to the folder at the same time, a cache will queue
them up for processing, but when I drop 3 files into this folder, only the
1st (sometimes the first two) cause the event to fire.
