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.
View 5 RepliesI have a variable number of usercontrol on a form Each time the user interact with one of the controls, I need to update a global state on the form.Each time I write a new control, I added a call to the Update function, but don't like it. I may add a new control and forget to write the call. Worse, I are repeating the call many times.
It does not look good.I changed all the user control to inherit from a class in which I coded a LostFocus event, updating the global state each time the used abandon the control, but it does not work if the user does not migrate to another control, and the updating is not interactive meanwhile the user is editing the control.
[Code]...
but none of them fires after the user had interacted without losing focus; or I are wrong?
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)
[code]....
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?
View 8 RepliesI 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..

View 4 RepliesI 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
View 3 RepliesI'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 am going to handle an event to write all files in a directory to a text file.But only the last file's context is saved successfully, I think that because of overwriting.

I want my program to be able to create a '.txt' file when it is run for the first time, with the date and time the program was accessed, and to be able to add new 'logs' of program history every time it is accessed. What i mean is that i want my program to be able to create a '.txt' file, and then fill in the dates and times when the program is opened.
View 7 RepliesBut i've a problem, everytime i hit the button "Save Settings" in my form/application it will re-save the settings to ini file, causing duplicate entries :(
Does anyone knows how can i avoid it to happen?
And, how can i retrieve a setting from the ini file to a textbox or messagebox or something?
(before anyone start saying me to use .xml, i was reading and i prefer the .ini files to what i'm doing)
So I have an application which uses MSSQL server as datasource. Is there anyways I can avoid using any database server and use a local file as datasource ?

View 6 RepliesI created a background thread that constantly scans a specified folder for any .xls files that are created or modified. These files come from a vba macro in outlook that will automatically save the attachments of the mails in the this folder. This will update the modified date/time, or at least it seems to.
For Each fi In aryFi
fidate = System.IO.File.GetLastWriteTime(path & fi.ToString)
fidate1 = System.IO.File.GetCreationTime(path & fi.ToString)

Everytime I check to the code, the fidate and fidate1 variables are indeed the correct dates/times of the file it's currently checking. It almost never gets inside the elseif block at runtime though.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?
I need to add this line to a text file that is going to have other information added to it several times. I also need to add this line and have the number change every time the additional data is added.
View 6 Replies.NET masters!Im working on a VB.net file management program that copies 100,000s of small images (20 - 300 KB).At least it tries to. When doing large multi-hour operations I start getting exceptions with the"Insufficient system resources exist to complete the requested service." error message.In a few cases the computer has then crashed.After a lot of debugging, finally with livekd kernal dump I can see that the System PTEs in the Kernel Mem are getting very low.I can monitor the PTE's in realtime with Performance Monitor with the Memory/Free System Page Table Entries.After an hour or so the PTE's start dropping in what appears to be linear fashion as the program keeps copying.Im sure it is the copy function causing the problem, as when i let the code run but with the copy routine commented out, the free PTEs stopped going down.Behaviour is identical with both of these calls. System. IO. File.Copy(strFileSource, strFileDest, bOverwriteFile) My.Computer. FileSystem. CopyFile (strFileSource, strFileDest, bOverwriteFile)If I stop & close the program, PTEs do not seem to rebound at all. If I start the program again, the PTEs again start going down.SO: What is up with File.Copy? Why is it using and not releasing all these PTE's? Seems this memory should be free after the copy.How can I change my code to avoid running up the PTEs?The test computer is Windows XP sp2 with 500MB ram. (also been testing with 1.5 G ram)Ive found some helpful documents on PTEs, which discuss system configuration via registry settings. But this is not really an option for me as this is a commercial product that others will be using on their own computers.Detection, Analysis, and Corrective Actions for Low Page Table [code]

View 5 RepliesI have been having problems with creating a download list of files for a downloader and was getting unexplained "File Does Not Exist" returns. My .avi files were returning found but but .exe and .txt files were getting the not exists.
I have now found by pulling in the whole directory and examining the file contents that my .exe files are showing ".exe.exe". My .txt files are showing ".txt.rtf". Wow, browsing the file directory in Server 2008 only shows a single extension. I don't see an option to display the extension as a column, just the "type". My directory looks like this:
Name Type
File1.exe Application
File2.txt Rich Text Document
File3.avi AVI File
I had renamed some of these files, maybe I just cannot rename files. I will try using originals ans see if I am ok. Maybe I need to rename the offending files without the displayed extensions. Is this just something weird with the server browser?
