Preserve date modified of files downloaded off of FTP

[Coding Camel]

Hi, i'm wondering if there is any way to preserve the date modified of files downloaded off of an FTP server using My.Computer.Network.Downloadfile

I know you could zip and unzip the file, but it sounds like a lot of trouble.

That is information is not part of the ftp transfer. Do a ftp request for GetDateTimestamp afterwards and use the FileInfo class to set LastWriteTime for the local file.
For Ftp clients that does preserve the date stamp, and display command sequences, you may see they do a MDTM after the RETR. Core Ftp is one such client where you can see this.

Okay, cool. I already have the file's lastwritetime info, so all I have to do is use the fileinfo class.

Uhhh, how would I set the lastwritetime with fileinfo? Do you have any examples?

 

[JohnH]

Here's an example: FileSystemInfo.LastWriteTime Property (System.IO)
You create the FileInfo object and set the property value.

Trying to figure out where i'd put this though.

That's easy, when you have downloaded the file and received the Date value, then you can set it for the local file.

I know this, but the only sub classes of Filesysteminfo are Equals and Reference Equals, how would I target something such as

("C:\TestFolder\" & File)

 

[JohnH]

Create the FileInfo object: FileInfo Constructor (System.IO)
Then set its LastWriteTime property.

object.property = value

                    Dim filez As String
                    filez = ("C:\PATHTOPLACE\" & File)

There is no property value for any files that I have declared.

Have a closer look at the code sample for FileInfo class, link in previous post. Understand that you need a FileInfo object.

Post got deleted? Anyways, I got the file property working. I didn't see that example part =) I am wondering if there is anyway to open a msgbox whenever Network.Downloadfile completes.

No, it was a different topic, so it was split to a new thread: http://www.vbdotnetforums.com/net-sockets/57256-download-multiple-ftp-files.html
