How To Tell System Copy Source To Destination If Possible
Mar 30, 2011
I'm trying to copy a file, using System.Copy. The destination, if it exists, should be overwritten. I had been using a single line of code for about a month, without problems : IO.File.Copy(SourceFile, DestFile, True)But problems started about a week ago, when I started more advanced checks. Partially locked files fail to copy, and the destination gets deleted. Locked files, on the other hand, work correctly: they just trigger a file in use exception.So I added this line before launching the copy:Using TestForAccess As New IO.FileStream(SourceFile, IO.FileMode.Open, IO. FileAccess. Read, IO.FileShare.None) : End Using..This was supposed to launch an error if the file was in use. But it is to sensitive. Some files (such as thunderbird's abook.mab) trigger an error in this added code, whereas they copied fine before (and you can copy them in explorer).My question basically is: How do I tell the system: copy source to destination if possible; if not, don't break destination?

I want to copy a file from a UNC path (ex: \comnamedirnamefilename.txt) to a local destination (c:outputdir)
I have no compile errors, but when I run it, it throws an exception (System.IO.DirectoryNotFoundException). I'm absolutely sure the destination existst (it's referencing the destination directory). I've tried doing it with system.io.file.copy(source,dest)and my.computer.filesystem.copyfile(source,dest). Same result either way.

I'm trying to convert a DTS package to an SSIS Package. My package contains a Data Flow task that pumps data from an OLE DB connection to a Flat File destination.The data in the flat file needs to be arranged in a certain way (eg: spacing), So how do I do that? Is there any data trasformation tool that will help me achieve this? If so how would it be done?THE DTS CODE (to put things in perspective)
sLineItem = Space(10)
sLineItem = sLineItem & Space(10)
sLineItem = sLineItem & Space(10)[code].....

I have VS 2005 installed in my sytem fyi.We have two databases, say source database and destination database. The databases is in Oracle. Now we need to pull data from Source database, manipulate it and push it into the destination database on daily basis.We are planning to use VB .Net for this and would like to know if this is feasible. Using windows forms through VB .NET, is it possible to create a exe and schedule the exe on nightly basis to pull the data from source to destination.how to do this as for manipulation of data, there is no intermediate database for us?

I am looking for an open source .net DMS. I know in the post below there are some c++ but am not familiar with it so that would be much help.I found this post but is was asked back in 2009 so there might have been some progress or additions to this? Open Source Document Management System in .net? The reason for open source is that I would like to be able to integrate it into something else later on. I would also need it to be a desktop based system and not web based.

But I get error's when the index is out of range. in Delphi it works fine.
Added one line to convert..

May i specify a general path to my USB giving it a name or anything similar?

In my program I allow the user to copy a file from one folder to another. If the file already exists in the target folder I want it to be overwritten.
All that works just fine - I'm not asking how to copy files.
But here's an example
Source file is:-
\SomeMachinesomeFolderfile.xyz
Target is:-
P:file.xyz
This might at first look like two separate files but in this case P: is mapped to \SomeMachinesomeFolder so the source and the target are actually the same file and the file copy will obviously fail.
Of course I want it to fail but my problem is that the windows generic error message seen by the user is not very helpful. It says something simple like "... can't be copied because it's busy". If the user isn't very bright he doesn't realize he's selected the same file both as source and target and he doesn't understand why it's busy.
What I want to do is detect in advance that the source and the target are the same file and display a more meaningful message to the user and not even bother trying to copy.
So, is there a way to detect that
\SomeMachinesomeFolderfile.xyz
and
P:file.xyz
are actually the same file?

.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]

I'm trying to move a lot of pictures from FOLDER A to another, FOLDER B. However, some of the pictures already exists in the FOLDER B. This stops my program saying it cannot copy the pictures over because they already exist. I'm trying to make it so any pictures from FOLDER A will copy over the pictures in FOLDER B if they are similar in name. Like... Folder A's pictures will just replaced the Folder B pictures if they have the same name. I was told to use the System.IO.File.Copy tool. Here is my code.

I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
[code]....
I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.
