File Copy with log file

[Widget]

Hi,

I'm trying to copy files and folder from one location to other and provide a log file of files copied. The copy code works fine, just not sure how to get it to a text file. Can someone point me in the right direction? Thanks

StatusDlg.Show(MB_ICONNONE, false);
--copy = File.Copy("E:\\genesis\\backups\\*.*", "Z:\\backup\\genesis", true, true, false, true, nil);

-- Check to see if the File.Copy action failed by getting it's error code.
error = Application.GetLastError();
StatusDlg.Hide();

-- If it failed (not equal to 0), display a dialog informing the user.
if error ~= 0 then
    result = Dialog.Message("Error", "There was an error backing up the files. Please try again.", MB_OK, MB_ICONEXCLAMATION, MB_DEFBUTTON1);
else
    Dialog.TimedMessage("Notice", "Files Copied.", 5000, MB_ICONINFORMATION);
end

You can use a CallbackFunction - the last of the arguments passed to File.Copy() - to retrieve the info about which files are being copied, and write this into a text file for logging purposes.

Ulrich im not sure I follow. How do I do a callback?

It is documented in the help file.

Hi,

Still trying to work out this callback function. Below is what I have some what figured out. I get a "Error: attempt to index global 'arg' (a nil value)."
Any suggestions? Thanks

function callfunction(Source, Destination, Copied, Total, FileCopied, FileTotal)
	
   local nFilePer  = Math.Round(arg[5] * 100 / arg[6]);
   local nTotalPer = Math.Round(arg[3] * 100 / arg[4]);
    
  Progress.SetCurrentPos("Progress1", nFilePer);
  Progress.SetCurrentPos("Progress2", nTotalPer);
  Label.SetText("Label4", Copied);
  TextFile.WriteFromString("C:\\Backup_log.txt", Copied, false);
   
end

File.Copy("C:\\ACTS\\*.*", "C:\\ACTS2\\", true, true, false, true, callfunction);
