Windows explorer program

P: n/a
im writing a c# console application that copies files chosen from the windows
explorer. I chose the files i want to copy and then from the (right key) menu
chose my program.
the program starts fine but passes an error that the file(s) are in use ny
another user. This other user must be the windows explorer. Any workarounds
to free the files from the windows explorer?

Are you trying to copy files from Windows Explorer? I take it you have
created your own menu item to the Context Menu that Windows Explorer uses.
I'd be interested to learn how you did that!

Anyway, on to your problem: Are you creating a copy of the file before you
try to do anything else with it? What part of your program passes the error?
Is it the actual copy method? Are you using System.IO.File or something else?
Have you tried cloning the file?

You might need to show some code for us to help you better.

I have added my application to the context menu of windows explorer.
I wrote a short windows program which inserted the menuitem into the
register (guess you could edit the register manually)
Then i right-click on the files i want to copy and choose my program from
the context menu.
I tried IO.File and IO.FileInfo but both give the same error message that
the file is in use by another process.
I also have a Windows version of the application in which i can use two
different ways of getting the files onto a ListBox from which i submit the
copy for each file: first by the OpenFileDialog and secondly by dragdrop the
files from windows explorer. The first way works fine but the second way
gives the same error as the console application. Even if i clse windows
explorer before the submitting the copy, the error is the same.

The copy code i simply:

FileInfo fi = new FileInfo(filein);
fi.CopyTo(fileout, true);

or with File it was:

File.Copy(filein, fileout, true);

Jape,

I know this sounds silly, but your filein and fileout *do* have separate
paths, don't they?

Otherwise, I don't know what to suggest.

Have you included your code in a try...catch to see what the exact error
message is? I'm guessing that error would be "the file(s) are in use by
another user" or something to that effect.

You could use the code below to find out exactly what type of error you are
getting. This should help you narrow it down.

try {
File.Copy(filein, @"C:\Temp\" + filein, true);
} catch (System.IO.DirectoryNotFoundException err) {
MessageBox.Show(err.Message);
} catch (System.ArgumentException err) {
MessageBox.Show(err.Message);
} catch (System.UnauthorizedAccessException err) {
MessageBox.Show(err.Message);
} catch (System.NotSupportedException err) {
MessageBox.Show(err.Message);
} catch (System.IO.IOException err) {
MessageBox.Show(err.Message);
} catch (System.IO.PathTooLongException err) {
MessageBox.Show(err.Message);
} catch (System.ArgumentNullException err) {
MessageBox.Show(err.Message);
} catch (System.IO.FileNotFoundException err) {
MessageBox.Show(err.Message);
}

I'm not sure what FileShare mode FileInfo and CopyTo use by default. If the
explorer keeps the (selected) file open, you will be denied access unless a
FileShare mode that allows the file to already be open by another process is
used. You may need to open (FileInfo.Open) the input file with a FileShare
including Read access.

I found out a new "feature" in the problem. The means of the application is
to copy files form a development server to seversl production servers. Our
main development server is a w2000 based server. We also have another
development-server which is a w2003 server.
From the w2003 server the copying works fine so it seems that the problem
exists only on the w2000 server. Unfotunately its our main dev-server and
wont be upgraded for some time to w2003 or w2008.
Oh, and the error message is: System.IO.IOException: The process cannot
access the file '\\SERVERX\jtest1\testi4.asp' because it is being used by
another process.

And this SERVERX is the w2000 server.
