Is there anyway to reliably know when a large file has completely finished copying to a particular folder? For example, Computer1 copies a large file to Server1Share1. On Server1Share1, I want to do something AFTER the file is done copying, without Computer1 intervention.

I'm trying to browse for a large file and copy it with a background worker but get the folling error:"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."

I'm using "My.Computer.FileSystem.CopyDirectory(...)" to copy large directories (30-50gb) from one mapped share folder to another. Using "FileInfo.length" to add up all file and subfolder sizes, determines the 'origin directory' size just fine. However, if I use the same method for determining the size of the 'destination directory', mid copy, it returns the full file size, despite the copy not yet being complete.I'm at a loss as to why, as this method works fine in testing, going from a local PC t

How do you recommend I copy large files over the LAN (>20GB)Currently I am using File.Copy.Another question I have is how can I implement this class to be self contained, meaning that it would report progress to the object that called it? or do I have to define a delegate in the calling object?
Code:
Public Class cCopier
Private Delegate Function CopyProgressRoutine(ByVal totalFileSize As Int64, ByVal totalBytesTransferred As Int64, ByVal streamSize As Int64, ByVal streamBytesTransferred As Int64, ByVal dwStreamNumber As Int32, ByVal dwCallbackReason As Int32, ByVal hSourceFile As Int32, ByVal hDestinationFile As Int32, ByVal lpData As Int32) As Int32

I have a requirement that users be connected via the LAN for a small service I am writing. Simply check My.Computer.Network.IsAvailable isn't enough because that will detect any network (e.g. wifi). I need to check whether or the user is LAN connected (and can therefore connect to an Oracle DB)

I have researched the Internet and found more than a few potential solutions, but I keep getting errors on a Windows 7 machine. Here's the scoop. I have an application written in VB.NET that launches a console application. The console application will run independently of my VB.NET app, so the user can close and restart the VB.NET app and potentially start a second session of the console app from the same installation.

VS2008 SP1, Winforms solution, VB.NET, compiling for x86 and .NET v2 I have about a dozen projects in the solution, with a couple of Windows forms projects and some class libraries. If I rebuild the solution, it clears out and recompiles all the projects, as you'd expect... and then disappears without trace or error message. Since I'm reconnecting to VSS 2005 over HTTP across the internet, it takes all month to start back up with everything loaded, so it's incredibly irritating. The compiled application itself works fine, and normal build and run after changes also works fine.
EDIT: Just to clarify, No add-ins except Refactor! (I know, I guess I ought to try uninstalling it to see if it's that, but it's just too useful! - I will see if there's an update though). And no custom build steps. It's just a vanilla Winforms app, with references between the projects (and some references to COM dlls for interop).

I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

View 4 RepliesI am working on server side application of FB login.Having converted the example here:[URL]..To VB, and using System.Net.WebRequest.Create to retrieve the responses I am now able to get a text string including the access_token and the expiry time in the following format: access_token=ACCESS&expires=2577
Obviously I can split this into an array and split the parts to get the access_token But, on the FB Developers example above, they do it with PHP like so: $params['access_token'];Is there a VB.net way of doing this? This seems more reliable to me than teh aforementioned splitting idea, ie, if FB change the output format.

So, I have a task where I need to basically copy about 600,000 PDFs, some of which can be 5-6 MBs from one network fileshare to another network fileshare on another pc.Now, I crawled through the directories, sub-directories etc etc and created what I call a Filename/Filepath Database lookup table. This table contains the name and the unc fileshare path of each file which comes in handy.I have used Multi-threading and File.Copy to "copy" the files and I getting about 45K files per 4 hours which I need to be significantly faster then that and I am seeing performance degrade over time

View 15 RepliesI have the following code where I make an copy of my database that I use. the code executes 100% but the problem I have is I'm not able to access my database afterward.I get a "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." and so if I restart the application it all works fine again.I'm certain the reason is because I can only access that database using a specific account name and password which is not account I'm logged in with.What i want to try is to default that database mdb to the point where no user is accessing it, or to reassign the the only account name that can access it to that database mdb. I've tried playing around with file security but had no luck.

I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

View 5 RepliesI have added two images as a resource in my project. I'd need to copy these images to a certain folder when the program is started. I'm not familiar about using resources, so far I have managed to set a picturebox to show one of these images like this:
Dim res() As String = GetType(Form1).Assembly.GetManifestResourceNames()
pBoxTest.Image = New System.Drawing.Bitmap( _
GetType(Form1).Assembly.GetManifestResourceStream(res(0)))
But I don't know how to get the url of that image so that I could copy it from it's url to another place.If I now try to find out the location of that picturebox's image I get an empty string: MsgBox(pBoxTest.ImageLocation)This should work in any computer where the program is run so of course I can not just hardcode the path of this resource.
