Hello,

Using macOS Mojave Version 10.14.2 on Mac mini (Late 2014), 3 GHz Intel Core i7, 16 GB 1600 MHz DDR3 with Xojo Version 2018 Release 4
I have read this... https://nug.xojo.narkive.com/5iB1iodb/show-me-in-the-finder

and I have tried the following...

dim ae As AppleEvent
ae=newAppleEvent("misc", "slct", "MACS")
ae.folderitemparam("----") = app.gf

if not ae.send then
MsgBox "Finder not running."

else
ae = newAppleEvent("misc", "actv", "MACS")   // the folderitem is not highlighted in its parent folder
'ae=newAppleEvent("misc", "mvis", "MACS")   // the folderitem is not highlighted in its parent folder

if not ae.send then
MsgBox "Finder not running."
else
'MsgBox "Finder is running."   // if this is uncommented the msgbox is displayed indicating "Finder is running."
ae.folderitemparam("----") = app.gf
'MsgBox app.gf.name   // if this is uncommented the msgbox is displayed indicating the correct app.gf.name
end if

'app.gf.Parent.launch   // if this is uncommented the correct app.gf.Parent is launched
end if

Any help/suggestions as to why the folderitem is not highlighted in its parent folder?

Thanks.

Lennox

const cocoa = "Cocoa.framework"
  
  declare function NSClassFromString lib cocoa (name as CFStringRef) as Ptr
  declare function sharedWorkspace lib cocoa selector "sharedWorkspace" (id as Ptr) as Ptr
  declare function selectFile lib Cocoa selector "selectFile:inFileViewerRootedAtPath:" (id as Ptr, fullPath as CFStringRef, rootedAtPath as CFStringRef) as Boolean
  
  dim ws as Ptr = NSClassFromString( "NSWorkspace" )
  dim sws as Ptr = sharedWorkspace( ws )
  
  dim path as String = "/full/path/to/file"
  
  if NOT selectFile( sws, path, path ) then
    beep //Error
  end if

Didn't I read somewhere that AppleEvent processing was now restricted in someway with Mojave for "Security" reasons?

That link you posted is over 9 years old

https://docs.xojo.com/AppleEvent

In order to use AppleEvents on newer versions of macOS (Mojave and later) you will need to include the NSAppleEventsUsageDescription key in your plist file.

10 seconds of research goes a long way

Thanks Dave, wasn't aware that AppleEvent processing is now restricted in someway with Mojave for "Security" reasons.

So, is there another way to show a folderitems in the finder?

Thanks again.

updated my response

Hi Dave,

I don't know what is meant by "updated by response", kindly explain.

Thanks.

Lennox

@Lennox J — Yes, you can use declares. It is not complicated but long. Just give me some time

@Lennox J Hi Dave,

I don't know what is meant by "updated by response", kindly explain.

Thanks.

I mean I added more to my response since you read it.... including a possible solution

Thanks Stéphane Mons, works well.

Will try Dave's suggestion/method later.

Thanks again Stéphane & Dave.
