FolderItem length without user dialog

Getting Started
1

I have the following code in a Method on a Window:

fiFile = GetFolderItem(oLrC.Path)
if fiFile.Exists then
lblFileLocated.Text = kCheckMark
tfFileSize.Text = fiFile.Length.ToString
end if

Since I haven’t executed a ShowOpenFileDialog it returns 0.

Is there a way to get the file size without going through a dialog?

thanks

Is the file “cloud” based and needs to be downloaded, whcih the open file dialog would be doing for you?

3

You could use binarystream to open the file & report the length from that.

It is on Dropbox right now but I need to code to work on a local disk. I’m just testing now.

Great, I’ll have to research how to do this but I’m sure it’s documented.

Thanks

If it is on dropbox, and is online only, the file will exist but be 0 bytes locally. Download the file locally through dropbox and try again.

Also are you pointing to a “bundle” eg an app on macOS. These are folders and would be 0 bytes

FWIW, I don’t see this. I am using Dropbox on File Provider. Online-only files showing the “Not Downloaded” icon in Finder correctly report their size. This is visible via ls -l in Terminal and FolderItem.Length in Xojo. It of course hasn’t been downloaded, but it does have the metadata for length that it is providing via the File Provider API.

Consider using a shell command..

dir *.log > filelist.txt

After that, a text file will exist containing file names and length.

You can open that and read line by line.

Var F As new FolderItem(SpecialFolder.Desktop.Child("MyPicture.jpg"))

Messagebox(F.Length.ToString)

This will work.The file must exist though for the messagebox to work…No need for a FileOpenDialog.

Is your app sandboxed? If yes, macOS will not grand you access unless you select the file with a fileopendialog.
