File copy with progress

[Johnny Jörgensen]

Using File.Copy in the System.IO namespace, it's easy to copy one or more
files.

But I wonder: Is it possible to get windows to display its File Copy
Progress dialog at the same time - or alternatively get callbacks with the
progress?

Same goes for deleting files...

Cheers,
Johnny J.

This can be achieved by means of a call to the Shell function
ShFileOperation . You can do this from your .Net program by means of Platform
Invoke. The declaration, along with some sample code, can be found at
pinvoke.net:

Thanks a lot, Alberto, I'll look into that.

Yes, using P/Invoke with SHFileOperation API is the long and risky way
to write the whole code error-free, that's why My namespace in VB.NET
provides a well-wrapper for this:

My.Computer.Fil eSystem.CopyFil e("source","des t", _
True,FileIO.UIC ancelOption.DoN othing)

The third parameter, which is "showUI", lets you to view native dialog
while copying is in progress.

http://msdn.microsoft.com/en-us/libr...yf(VS.80).aspx

Though yours is cross-post, you can call the same function in C# by
referencing it to Microsoft.Visua lBasic.dll from .NET tab in "Add
Reference" menu with the following code:

using Microsoft.Visua lBasic.Devices;

Computer copyfile = new Computer();
//Pass parameters below including showUI
copyfile.FileSy stem.CopyFile(. ..);

Hope this helps,

Minor correction related to code above from myself, use that instead:

My.Computer.Fil eSystem.CopyFil e _
("C:\source.txt ", _
"C:\folder\dest .txt",
Microsoft.Visua lBasic.FileIO.U IOption.AllDial ogs, _
FileIO.UICancel Option.DoNothin g)

In addition to the other replies:

Wrapper around 'CopyFileEx' using the progress callback (suitable for
copying single files):
