[Closed] FilePreOpen FilePreMerge Filename

if file doesn’t exist it will not be loaded or merged.
you can use #filePreOpenProcess which tells the filename to be loaded, but there is no solution anyway to interrupt the loading or merging process.
if you want to check anything about a file before loading(merging) make your own loading interface.

I understand, I have made my own loading interface already, but is it possible to replace the default one by script? I need to replace both, from the menu and from drag and drop.

I am not sure if this time I understand what you need to do and so if this code will be helpful, but I am hopping I got it right.

(
   	global PreOpenProcess, PreMerge
   	
   	fn PreOpenProcess = format "OPEN: %
" ((callbacks.notificationParam())[2])
   	fn PreMerge = format "MERGE: %
" sysInfo.currentdir
   	
   	callbacks.removeScripts id:#ID_0X5DD9E10A0X2925901
   	callbacks.addscript #filePreOpenProcess "PreOpenProcess()" id:#ID_0X5DD9E10A0X2925901	
   	callbacks.addScript #filePreMerge "PreMerge()" id:#ID_0X5DD9E10A0X2925901
   )

Merge doesn’t work with Drag&Drop.

Thank you, Jorge and Denis.
So here is what I need to do:
I want to replace the way max opens files.

this is just a piece of code, in fact there is a lot more:

(			
			f = getOpenFileName caption: "Open File" filename: project_path types:"Max(*.max)"
			if f!=undefined then 
			(	
				local _verify = false
				_verify = loadMaxFile f useFileUnits:true quiet:true \
					missingExtFilesAction:#logmsg missingExtFilesList:&missingExtFiles \
					missingDLLsAction:#logmsg missingDLLsList:&missingDLLs \
					missingXRefsAction:#logmsg missingXRefsList:&missingXRefs
					if _verify==false then
					(
						(dotNetClass "System.IO.File").WriteAllLines (CMF) #(f, (1998 + (maxVersion())[1]/1000) as string) 	
					)
					else
					(
						redrawviews()	
						try(destroydialog ARConverting) catch()
						if missingDLLs.count>0 do
						(	
							clearplugins()
						)	
					)
			)
)

I would like to open max files in silent mode, verifying many things – network location, missing plugins etc.
I made this script and it’s working now smooth.
I just need now to replace the default opening/merging with mine.
I will try to play with your code, but I see I can’t use it to open in silent mode
