I've written the following code. It works fine for creating, deleting and renaming files. However when I set a file to read only, or modify the file (i.e open it in notepad and change the contents) nothing happens (it doesn't hit the change breakpoint)
I have the following
VB.NET
Private fsw As FileSystemWatcher
Public Sub WatchFiles(ByVal tblMappings As DataSet)
Can someone please help me create a very very simplistic sample page as the chat page included is too coomplete. something as simple as detecting a change in the database and displaying the word "change" on screen in realtime for any client connected.and I tried creating a global.asax file into which I added in the line mentioned in the link above, but it does not seem to like the word "Setup" in the line [code]
Imports System.IO Public Class Blah Public Sub New() InitializeComponent()
[code]....
When I run it and save changes to a file on my C drive, the code works great, except it executes the watcher_Changed() method four times. The changeType is "4" every time.
is it possible to get the name of the process that caused the change in the filesystem?i want to do this programmatically [ie, i can't use any external 3rd party tools like handle]
I want to be able to isolate an area of my desktop (similar to a screen capture snip) and evaluate if it is changing. In this particalr case it is an appliacation I have (not mine) that flashes an icon upon completion
What I want to do is make a small app that will detect change when I am away and perhaps perform a specific action (the action is not relevant really - i can take care of that) Again,this is NOT hugely important, but if someone has an idea or has seen an app that does this, it would be useful for me...
I put this in the VB.NET forum because I write 75% of my code in VB.... so I chose this instead of a general area !!
I've been attempting to determine if a notebook's lid has been closed when the power setting is set to "Do Nothing."I was able to get this to work by trapping the WM_POWERBROADCAST message, but it would only work when the computer when to sleep. I've tested this on many different notebooks and the results vary. Even when changing the power settings correctly, the results were fairly inconsistent.So I posted this question in General Developer and penegate offered a possible solution.[code] I'm thinking that maybe the message I'm trapping isn't correct, but I'm not 100% sure. When I Google that message, nothing comes up. Two links appear. The one on VBF and some German site. Nothing's on MSDN.
I've been using 'GetScrollInfo' to find the position of the scrollbar on a ListView and I can detect when it hits the bottom of the list. Is there anyway I can raise an event when the scrollbar changes? At the moment I have it working by using a timer but I would rather if possible create an event to fire my routine.
We can watch the file action by FileSystemWatcher but it give us to only create,rename,delete or replace action report, can we get file access action ? for example when user double click any file? or when run any application?
I have a FileSystemWatcher and whenever a file is changed/created it is uploading the file for me to an FTP. My problem is that it keeps uploading the same file 3 times.
I have to create a windows service which Monitors a specified folder for new files and does someprocessing on it and moves it to other location. I started with using FileSystem Watcher. But my boss doesn't like FileSystemWatcher and wants me to use polling on Timer or any other mechanism other than File System Watcher.
I'm using FileSystemWatcher to monitor a file on a windows server which links into a news ticker on our desktops. The ticker watches the file and updates accordingly. I've successfully got the ticker to watch for a creation and deletion which is great but the changed function doesn't seem to trigger. Out of interest, I tried this function on the network drive AND a local disk with the same results.
I've upped the buffer but I can't see what else I can do to change it! In the short term, we can probably live with just deleting and recreating the file with any changes that are required, but it would be nice if the ticker would just watch for file changes.
I have a filesystemwatcher that watches a certain folder.. Now i use system.thread.sleep to be sure that the file is completely copied to the folder that i watch..But this is not a good way!
I know there is a way to check if the file is open or used by another process, but i dont know the code..
I have a filesystemwatcher that checks for any changes on the files in a directory, it will then copy them to a new directory. I am getting an error saying that "could not find file C: TMPEFD.tmp", so basically when i edit the[code]...
I am making a file monitoring tool, what's the best approach in doing that and it returned that I should use filesystemwatcher, others suggested a polling program.
Here's my the current scenario:
My server path (local): C:FilServer
List of folder to monitor for created event: C:FilServerAB_Incoming - zip files C:FilServerAC_Incoming - xml and tif files
List of folder to monito for deleted event: C:FilServerAB_Outgoing - zip files C:FilServerAC_Outgoing - xml and tif files
When the folder raises event, the detected file will be following this routine:
Move the file to d:ackup and copy to e:source[date][time] and write sumary log.
I am working on a file access monitor wrapped up in a VB .Net Class. The ileSystemWatcher is working and my log file shows files when they are accessed. However, I am having trouble returning who or what accessed the files. For example....system services and processes should return something like NT-ATHORITYSYSTEM while a network share being accessed by another computer should return DOMAINUSERNAME and finally a process running in the background via "Switch User" should be returned as DOMAINSOMEOTHERUSER ....anybody have any ideas? I have searched high and low and have found nothing but other people asking the same question and people saying how it is not possible. the Sysinternals Process Monitor is able to output the correct results and its documentation states it was created using NET API however I can not find any references to any such API calls or combination of such. Should I be using something else other than the FileSystemWatcher? My code is below
I'm using FileSystemWatcher in an application.it monitors the files in a folder, then do some processing. I monitor FileCreate, Change, Rename, Delete event.the problem is: when I copy some images to that folder, it fired the create event, but the file is not actually ready, so, when I load the file in the event handler, it failed.how can deal with this correctly?
I created a VB Windows service with a FileSystemWatcher (VS 2005). When someone places an XML file into a folder, I want the service to read it, then move it to another folder. I do the move with this type of command:
Below is the part code I currently use to write to a file, Try Using sWriter As New IO.StreamWriter("C:Tmp.txt", False) sWriter.Write(m_Buffer.ToString) : sWriter.Flush() End Using Return True Catch ex As IOException End Try
But some time this results in error Access to the path 'C:Tmp.txt' is denied
My question is, Is there a safe way of detecting File access permissions, without handling exceptions, I mean if I can some how check before opening a file for any filehandle opened for it.
I am reading file with text contents on it.sample dictionary.txt contents:
aa abaca abroad apple
Snippet A:
Dim path as String = Server.MapPath("dictionary.txt"); Dim dictionary() as String = {} Try
[code]....
Basically, I want to make sure that I can handle/prevent this error.Does Snippet B, solves the problem, if not is there other way so that I can prevent this error.BTW, this a web application and I am expecting multiple users.
I have a vb .net application where the user can choose a directory into which an excel file is written. If the user selects a system directory (yes, my users do this, don't ask me why) then a System.Runtime.InteropServices.COMException is thrown at runtime. I am handling this exception telling the user to please select another directory.
I have my application watching my desktop, pictures, music, and document folders.[code]What would I need to put into logrename() in order for it to automatically upload the renamed file onto my server?
I can't seem to get a FileSystemWatcher to work, this is what I currently do.
Private Sub FileSystemWatcher1_Changed(sender As System.Object, e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Changed MsgBox("Directory has changed") End Sub
I have the filesystemwatcher path in my desktop. But when I create, re-name or delete something in the desktop it dosn't do anything, not even giving an error. I filter FileName, DirectoryName and LastWrite (the defaults).
The FileSystemWatcher have the EnableRaisingEvents set to true. So don't really know what the problem is.
I've tried google without any luck, all I found was people having problem that the FileSystemWatcher executed twice.
So do I have to do anything more on the code to get it to work?
I have a FileSystemWatcher in my project and when Created new file, i can get MD5 value of the new file, but sometimes error occurred while getting MD5 value, my code is like this
Private Sub FileSystemWatcher_Changed(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles SystemScanner.Changed Try
[code]....
That error is "Access Denied", i think function must be wait for done the progress, how can resolve this problem ?
I have a FileSystemWatcher monitoring a folder, and when many files are cut and pasted into the folder, the GUI freezes, as the 'Changed' event is fired over and over. Any way to deal with this?
I've been trying to get filesystemwatcher to work in my application with no luck. I've been able to modify the example on MSDN and have it work very well, but not when I try to use it in my own program. [Code]
If you compare it to the example, there really is very little difference, at least to me. "loadlist" is the equivalent of "main" in the example, "watchfile" is the equivalent of "run", and "OnChanged" is the same as in the example, but performing different actions. Right now its not doing anything. If I remove "Shared" from the subs then it works if the file changes once, but after that it does nothing. (I must admit I don't really know what making a sub "Shared" does).
I have a FileSystemWatcher tool on my form Watching 'C:' and i am now the FileCreated Code
Private Sub FileSystemWatcher1_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created Dim Name As String
So, I've got a text boxes which loads up a content from a XML file, usually a numbers I want a button, so when I will change the numbers on the text box, the data in file will change as well, in other words a save button That's how the data is being taken from a file
[code]...
Those EditPaths, Playa2 etc are making up a path to a file
