FileSystemWatcher - Multiple Zip Files?
Sep 13, 2010I am in the process of writing a windows service that will be replacing a vbscript that runs via a scheduled task currently. It currently runs on 350 kiosk machines in 350 different locations.Here is what the vbscript currently does:
1. The machine receives a ZIP file in the RECEIVE directory. Configuration_09122010_1234.zip. This file contains software configuration files that need to be copied to specified folders on the machine and to another machine on the local LAN where this kiosk is located.
2. The zip file is extracted to a folder with the same name as the zip file.Inside the zip file is an instruction file (.txt) and files that are referenced in the instruction file.
3. Opens the instruction file and performs the instructions in the file. Example: (this would copy pricingfile1.dbf to \mymachinecapplication1pricing, and then execute softwaresoftwarepatch1.exe which is located in \mymachinecpatches)
pricingfile1.dbf, \mymachinecapplication1pricing, copy
softwarepatch1.exe, \mymachinecpatches, run
4. Once all of the actions in the instructions file are completed, the folder where the zip file was extracted is deleted and the zip file is renamed to configuration_09122010_1234.zip.applied to show that it was processed by the script. Also, because the script is a scheduled task, this ensures that the file is not applied more than 1 time.
So I have started writing the service using the FileSystemWatcher. Basically I look in the receive folder for any file that looks like Configuration_MMddyyyy_*.zip and unzip it to a folder of the same name.
1. I have been doing some reading about the FileSystemWatcher Created event.I read an article about how the Created event fires as soon as the first byte is written but doesn't necessarily mean that the complete file has arrived at the machine. A post I read involved a .csv file and it mentioned that you try to open the file and catch any errors - if you cannot open the file, it hasn't arrived yet. This makes sense to me but I don't know what the equivalent would be to a zip file. It's not the same as opening a txt or csv file.
2. There are times that we send more than 1 configuration file in the same day, or even, at the same time. Above I mentioned the name was Configuration_<date>_1234.zip. The 1234 is a sequence number, always incremented. The idea is for 1234 to be applied before 1235 and 1236. So if I had 2 files sent *at the same time* and I want them to apply in order, how would I do this? I thought about when I am applying 1 file to stop looking for changes until after the apply process is completed, but then I *think* I would miss any file that arrived while I EnableRaisingEvents = false?
FileSystemWatcher And Locked Image Files?
Apr 13, 2012I have a filesystemwatcher waiting for .jpg files to arrive from the camera.he file system watcher invokes a delegate (it works but is that the proper way to handle it?) sub that does a couple of things:1. Adds the just arrived file name to a table2. Attempts to display the image in a picturebox on the form. When it displays the image it imprints some information on the image that the user has entered on the screen. I use a file stream to retrieve the image.The problem is, I'm getting a file in use orror on the "Img = ystem.Drawing.Image.FromStream(fs)"statement. Not all the time. Sometimes I can add three or four files to the folder in rapid succession with no issue. But then out of the blue the error will occur. Sometimes it's there to stay but other times it will go away and allow me to add morefiles.
View 2 RepliesFileSystemWatcher And Save Excel Files
Aug 21, 2011I am trying to write an app that monitora a folder, and subfolders, amd makes a copy of any file that gets saved there, (or renamed, moved etc). Filesystemwatcher does a pretty good job of it, untili someone saves an Excel spreadsheet. Excel does about 9 different file system operations just to save the file. What happens is I get events for tempo files being saved, then renamed, or deleted in a very quick succession. All I want is the final spreadsheet, but these changes happen so quickly is causes my app to crash. Anybiody have any thoughts on how to hendle this?

Will FileSystemWatcher Process Multiple Files At Once?
Jun 1, 2009I have a Windows service that is watching a folder for files that will be placed there.(Created in Visual Studio 2005.)The files each represent a transaction, and the transactions have to be kept in order.As I process each file (transaction), I want to forward it to someone else.(The someone else wants them kept in order.)It looks like I can't paste multiple files into a folder simultaneously and still be sure that they will be processed in the order of the original date and time they were created.Nor can I be sure that they would be read in name order.(FileSystemWatcher would grab them in any old order it chose.)So I think I will have to move the files into the folder one at a time, in the proper sequence.But I'm wondering if I could get into a "racing" situation.
When FileSystemWatcher detects a file in a folder, it creates a new thread for your event handler to operate on.If it detects a second file while still processing the first file, would it then create yet another thread?If that is the case, then if File1.xml takes longer to process than File2.xml, it seems like File2.xml might finish first, resulting in my transactions getting out of order.In my own experiments,I have not seen evidence that multiple files are really processed simultaneously.I write messages to a log file as I process each transaction, and I never see messages from File1.xml's processing intermingled with File2.xml's messages.This seems to be true even when I paste both files into the folder simultaneously.it only keeps one event-handling thread going at a time, and queues up the events as they come, processing them on that single thread.Otherwise, I'll have to do something to ensure they are kept in order.

Filter Files From A Directory Listing?
Mar 15, 2011I need to write a process which filters out 'old/dead' job files from a directory (actually two directories). This process needs to 'read' a number pattern (in a fixed position) off the filenames (for which there will almost certainly be duplicates), and having then 'got a list' of unique number patterns, give these to a function (which I already have) which will give a boolean, from which I can decide to either delete those files whose name contain this particular number pattern or not - this is intended to be run each night (windows task scheduler). Example directory content is:

I know I can get a listing using Directory.GetFiles(dirpath, "SUB_*.xml") but am stuck on how to go about the rest.
