Sometimes you want to be able to sort things in the same fashion as the Finder. This method when used as the comparison function for the Arry.Sort( delegate) form of sorting will do that

Public Function CompareLikeFinder(firstString as string, secondString as String) as integer
  #If targetMacOS
    // // 
    // // typedef NS_CLOSED_ENUM(NSInteger, NSComparisonResult) {
    // // NSOrderedAscending = -1L,
    // // NSOrderedSame,
    // // NSOrderedDescending
    // // };
    // 
    // // this gives us "Finder like" comparisons
    
    // -[NSString localizedStandardCompare:].

Sometimes its useful to be able to be able to tell your user if they need to enable full keyboard access

You can tell if its enabled with this method

Public Function FullKeyboardAccessEnabled() as Boolean
  #If TargetMacOS
    Try
      Declare Function NSClassFromString Lib "Cocoa" (name As CFStringRef) As Ptr
      Declare Function GetSharedApplication Lib "AppKit" Selector "sharedApplication" (target As Ptr) As Ptr
      Declare Function IsFullKeyboardAccessEnabled Lib "AppKit" Selector "isFullKeyboardAccessEnabled" (target As Ptr) As Boolean
      
      Dim AppClass As Ptr = NSClassFromString("NSApplication")
      If AppClass <Nil Then
        Dim AppObject As Ptr = GetSharedApplication(AppClass)
        If AppObject <Nil Then
          Return IsFullKeyboardAccessEnabled(AppObject)
        End If
      End If
    Catch Err As RuntimeException
      Return False
    End Try
  #endif
  
  
  // windows & linux can tab to EVERY control anyway
  return true
End Function

macOS adopted an interesting behaviour some time ago where when you opened a new window in an application. It would default to opening a new tab in the window instead of opening a new window.

If your application could not deal with this and the user had the preference in System Preferences > Dock > Prefer Tabs when opening documents set to Always then it could cause your app issues.… Read the rest

This has probably been posted in the forums. Its just not always easy to find.

Declare Function NSClassFromString Lib "Cocoa" (name As CFStringRef) As Ptr
Declare Function sharedWorkspace Lib "AppKit" selector "sharedWorkspace" ( obj As ptr ) As ptr
Declare Function selectFile Lib "AppKit" selector "selectFile:inFileViewerRootedAtPath:" ( obj As ptr, fPath As CFStringRef, rootFullPath As CFStringRef ) As Boolean
Dim workspace As ptr = sharedWorkspace( NSClassFromString( "NSWorkspace" ) )

Call selectFile( workspace, f.NativePath,
