Apr 23, 2010In the following code as you see I am defining myFile inside the timer sub; which of course is not a good idea. The FilePath is derived in form load before the timer kicks in. How can I declare myFile globally so it can be used in timer sub as well as in form load?

View 5 RepliesEquivalent For [Field: NonSerialize] (object Cloning)?
Mar 3, 2009I am attempting to deep clone many of my objects via serialization. Most of it works fine, except when the original object has event handlers for their events. Then the holders of the event handlers are being cloned as well. Anyways, from web browsing it appears the right way is avoid cloning the events. However, you cannot put <NonSerialized> in front of an event declaration, but the C guys seem to get around this by writing [field: NonSerialize] (I guess directing the program to the underlying field, over my head). What is the VB .Net code equivalent to this, as I can't find it?

View 9 RepliesOrder By Fileinfo Extension And Name?
Nov 30, 2011I'm using this query:
Dim FilesDirsQuery = From file In
_directory.EnumerateFileSystemInfos()
Select file.Name, file.Extension
It gets all files and directories in the _directory. But how to order the query by extension and name?
So I found that I have to use this to order by extension:
Dim FilesDirsQuery = From f In
_directory.EnumerateFileSystemInfos()
Select f.Name, f.Extension Order By Function(f As IO.FileInfo)
Return f.Extension
End Function
And I have to use "ThenBy", but it can't be used in my example. So I tried:
FilesDirsQuery.OrderBy(Function(f As IO.FileInfo)
Return f.Extension
End Function).ThenBy(..)
But it say's that my nested function doesn't have a compatible delegate. So what should I do?
Access Pen Drive (MP3 Player) Via FileInfo?
May 13, 2009I've got a Samsung Q1 attached to my computer, and I was hoping to use the FileInfo / DirectoryInfo objects to access the file on the device, however what I right click on a file in windows explorer I get a location of COMPUTER/Q1/DATACASTS/mine.mp3, and when I feed this into the DirectoryInfo object I get "Invalid network drive"
Something tells me I'm going about this the wrong way ... Is there a differant object I shoud use, or is my location string incorrect in format
C# - Filepath With System.IO.FileInfo When Used With Log4net In A Wpf App?
Mar 19, 2012I have used log4net in winforms before. First time using with a wpf console app. The console shows up and the console appender works exactly as in the winforms app. However in winforms I never had to give the full path to the log4net xml file. It is located in the same place where all the cs files are. (the default place where VS 2010 puts all its source files. So
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo("log4config.xml"));
works in a winforms app's Program.cs->main() but for the wpf version where I have my own Startup class with my own Main() (instead of the autogenerated and hidden main()) I have to change the line to look like this
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"c:fullpathlog4config.xml"));
This took me quite a while to nail down so I thought it may be worthwhile to figure why this is so. Anyone know ? I am using log4net ver 1.2.10.0. The log4net dll and xml both have copy to local = true in winforms and wpf.

View 5 RepliesSystem.IO. FileInfo Performance Loss?
Mar 9, 2009I'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!

View 10 RepliesAsp.net - Why Is FileInfo Showing An Extra File Extension
Sep 6, 2009I 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?

View 2 RepliesVS 2008 Attachment Class Combined With FileInfo
Oct 29, 2010OK I am working on a windows service that monitors specific directories and checks to see if a file is changed. If a file is changed, it is attached to an email and sent to an admin.
The way I solve the problem...
I create a FileInfo object to do the following:
-I check to see if the file has an extension that is allowed to be attached
-I check to see if the file is under a max size to be attached
I create an Attachment object to do the following:
-attach the file to an email
I then send the email. The problem with this is when I edit the file after it is successfully attached the first time, I CANNOT save changes to that file. I get an error message saying that it is being used and cannot change it. My solution to this problem is to call the "dispose()" method of the attachment class. When i do this, I can edit the file all I want to and the first attachment works but after that the "dispose()" method always throws an exception and the file is never attached to the email when the file is edited again. Why is this happening?
File Copied With FileInfo Not Able To Be Read By Shelled Program?
Jul 3, 20112 - Saves the server XML file it into a folder separate from the root folder of the application.3 - Deletes the local XML file in the root folder of the application.4 - Copies the server XML file to the local folder of the application.5 - Opens the application.6 - Closes the updater.Now when the application opens, it reads this XML file in the local folder. When I run it stand alone, it works fine and can find this XML file. However, my problem is when the application is opened by the updater, it can't read the XML file in the local folder. I check for this file doing File.Exists(XMLfilename) and it returns false but like I said, if I close the application and reopen it it works fine.
I'm thinking that for some reason the updater is "locking" this file so my other process can't read it? I can't close the process before I open the original application so I'm not sure what's happening here. My Update Folder is the users ApplicationData folder and the root directory of the application is in the Program Files folder.
This is my code in the updater:
Dim ImageDir As DirectoryInfo
