Check Resource file-s integrity during App runtime

[Eagle]

Here's an example functionality that assists with ensuring resources
essential to correct running of your App are present and 'correct'

--[[Example function to check App runtime resource files whenever called-exit if 'anomolies'.
	modify to suit as allways. May Not be practicle if App Runs from Optical Media and-or
	many-large rescource files, however for smaller Apps any 'OnShow' delays are minimal,
	depending on what you wish to target. ]]


function APP_TERM()

Window.Hide(Application.GetWndHandle());
Folder.SetCurrent(_TempFolder);
--perform any cleanup or other actions here

if bShowAPPEndmess then
	--example display strings(could be allocated on Startup Actions)
	local strNoAppStart = " - This Application Will Not Continue -";
	local strNoAppBod = "Application must be properly Installed\r\n This Application will now Close";
	Dialog.TimedMessage(strNoAppStart, strNoAppBod, 8000, MB_ICONINFORMATION);
end
Window.Close(Application.GetWndHandle(), CLOSEWND_TERMINATE);

end


--SREsources
function EnumResources()

local bRescVerif = true;

--[[set your table-s structure to suit- one example method only here,based on crc values,
	pre-determined for a runtime rescourse location, (must be in order to work)]]

local tResIm = {12345678, yada yada, etc, etc, etc}; --for simplicity: numeric order of id values
local tRBins = File.Find(AppRescoureFolderpath, "\\*.*", false, false, nil, nil); --recurse off for example.
if (tRBins) then
	if (Table.Count(tRBins) >= 5) then
		Table.Sort(tRBins, nil);
		for n, bin in tRBins do
			if false then break end
			if (File.GetCRC(bin) ~= tResIm[n]) then
			bRescVerif = false;		
			end		
		end
	else
	bRescVerif = false;		
	end	
end
if (not bRescVerif) or (tRBins == nil) then
	bShowAPPEndmess = true; -- show a timed message or not.
	APP_TERM();
end

end
--EREsources


--the call (best placed on the 'OnPreLoad' event for each page of App) and OnStartup actions 

EnumResources(); --could add target paramaters to expand functionality etc.
