Hidden files attribute Error

[mikzik]

-- read attribute from dummy file
attrib = File.GetAttributes(_SourceDrive.."\\pagefile.txt");

-- read and create ISO format of AccessDate
strAccessDate = attrib.AccessDateISO;

-- display AccessDate in format  2007-09-14T11:34:54
Dialog.Message("", strAccessDate);

This work fine, but if I change pagefile.txt to pagefile.sys which is hidden and system file
I get error mesage:

Error
On Next, Line 9: attempt to index global `attrib'(a nil vaule)

For some reason it cant read attributes from hidden files!
Any Hint?

This is a "known" issue.

I use FSO to get around this -- here's my "fso" file -- it has some functions that are "swapable" with the stock ones (takes the same paraeters, and returns the same data) It needs my BitWise Plugin

-- SUF's LUA objects (file.) don't handle hidden/system files very well
-- this wraps those items with fso objects.

function FSOFileThere( cFile ) 
	local bFileThere = false;
	--dbgout("Testing for file",cFile);
	if not Empty( cFile ) then
		local oFSO = luacom.CreateObject("scripting.filesystemobject");
		if oFSO then
			local cDrive = JustDrive( cFile );
			if not Empty(cDrive) then
				--dbgout("Getting status for drive",cDrive);
				local oDrv = oFSO:GetDrive( cDrive ) ;
				if oDrv then
					if oDrv.IsReady then
						bFileThere = oFSO:FileExists(cFile) ;
					end
				else
					bFileThere = File.DoesExist( cFile );
				end		
			end
			oDrv = nil;
			oFSO = nil;
			collectgarbage();
		else
			bFileThere = File.DoesExist( cFile );
		end
	end -- empty()
	return bFileThere;
end

function FSOFileVersion( cFile ) 
	local cVersion = "";
	if File.IsThere(cFile) then
		local oFSO = luacom.CreateObject("scripting.filesystemobject");
		if oFSO then
			cVersion = oFSO:GetFileVersion(cFile) ;
			oFSO = nil;
			collectgarbage();
		else
			cVersion = File.VersionInfo( cFile );

	end
	return cVersion;

wow, I will need time to analise this
Thanks

Get the bitwise plugin & put that code into a lua file and add it into your project.
then use File.Info() just like you'd use File.GetAttributes()
