    I figured this would be easy..

     

    I'm working on an app that needs to read data from a com port - this I have code for. I'm having trouble finding something (that actually works), that can "simulate" data being sent to the port so that it can be read from the app. Simulation is needed because I'm remoting to the machine in question and I'd rather avoid having to (or for someone else to) go to where the machine is to connect a device that might not even be suitable. 

     

    I have come across this: https://www.aggsoft.com/com-port-emulator.htm, however I'm unable to work out exactly how it is supposed to emulate (when clicking "Start", it prevents anything else from accessing the port) or it's just not suitable anyway.

     

    I used to work on apps over 20 years ago (using Delphi 3) that did this kind of thing, but we had the luxury of having the actual hardware with us. That's about how long it has been since I've done this kind of thing.

    Best way, 1- Export SDK from Delphi IDE Tools->Options->SDK Manager select SDK and export and import it in the new Delphi IDE

    That the export option exists had slipped my mind.. I'll update my article; thanks!

    I upgraded Xcode to 12, my iPhone to iOS 14

    You'll find you won't be able to debug with a device that has iOS 14.0. Deploying will work; just not debugging.

    Going back to SDK 13.6 does not help so I guess this has to do with Xcode.

    Because Delphi does not import the iOS 13.6 SDK correctly, either (as well as iOS 14.0). Use iOS 13.5 SDK if you can - it comes with Xcode 11.5. I wrote about it here:

    I expect you'd need to patch the TBaseWebViewDelegate.AuthenticateForHost method in FMX.WebBrowser.Delegate.Cocoa unit, and pass the username and password instead of using TDialogServiceAsync.InputQuery.

     

    I'd recommend submitting a feature request in the Quality Portal for an OnAuthenticate (or similarly named) event to make this easier.

    I've already answered your email, but for the benefit of others:

     

    On iOS, you can check what the user has authorized with: 
      TCLLocationManager.OCClass.authorizationStatus

    which will return one of the following values: 

      kCLAuthorizationStatusAuthorized = 3;  // User has authorized location services ("always" on iOS 8+)
  kCLAuthorizationStatusDenied = 2; // User denied authorization for your app, or they turned off location services in the device settings, or the device is in airplane mode
  kCLAuthorizationStatusNotDetermined = 0; // App is yet to request permission for location services
  kCLAuthorizationStatusRestricted = 1; // User is unable to authorize location services due to restrictions such as parental controls
  kCLAuthorizationStatusAuthorizedAlways  = kCLAuthorizationStatusAuthorized ; // See kCLAuthorizationStatusAuthorized
  kCLAuthorizationStatusAuthorizedWhenInUse = 4; // User has authorized location services only when the app is in use 
     
    (from iOSapi.CoreLocation unit)
     
    If your app needs location services and the status is kCLAuthorizationStatusDenied, you could present a message asking if they would like to change the settings, and if they do, execute OpenSettings: 
    uses
  Macapi.Helpers, iOSapi.Foundation, iOSapi.UIKit, iOSapi.Helpers;

function UIApplicationOpenSettingsURLString: NSString;
begin
  Result := CocoaNSStringConst(libUIKit, 'UIApplicationOpenSettingsURLString');
end;

procedure OpenSettings;
begin
  TiOSHelper.SharedApplication.openURL(TNSURL.Wrap(TNSURL.OCClass.URLWithString(UIApplicationOpenSettingsURLString)));
end;

    This will take them to the Settings app, and show the settings specific to your app (there may be a little delay in it changing to the settings for the app)

    You appear to have 2 certificates on the Mac that are the same. Perhaps one is expired. To check this, on the Mac in Applications/Utilities, run the Key Chain Access app, ensure that expired certificates are listed by clicking Show Expired Certificates in the View menu, and select login in the Keychains list, and My Certificates in the Category list:

    For any expired certificates, right-click them and click "Delete"

    What is the Bundle Identifier and how do I find out what it should be

    The bundle identifier needs to match the identifier given to the App Id that was created for the application on the Apple Developer website, e.g I created this one for testing Firebase Cloud Messaging (for myself - you need to use your own):

    The convention is to use reverse domain notation (if you have one), or at least something that should be globally (literally) unique.

     

    This is also the App Id that you would have enabled Push Notifications for:

    I expect this is not going to be possible, however I thought I'd ask just in case someone has a brainwave of some kind.

     

    I'm working on a DLL which implements a virtual channel for Windows terminal services, and a desired function is for it to be able to "self-update". It fetches a file which is the new version of the DLL, and is supposed to "move" the file in-place.

     

    Needless to say I've tried to make it work, with the inevitable "access denied" errors when either attempting to rename the original file then replace it, or just copy over it.

    I can send you the apk, if you want or interesting

    You could send it if you like, however I think it may be resolved only by seeing the code being executed at startup. You can direct message me the source if you like. I will treat it in confidence.

    The following worked fine for me: 

    procedure TForm1.Button1Click(Sender: TObject);
begin
  PermissionsService.RequestPermissions(['android.permission.READ_EXTERNAL_STORAGE', 'android.permission.WRITE_EXTERNAL_STORAGE'],
    procedure(const APermissions: TArray<string>; const AGrantResults: TArray<TPermissionStatus>)
    begin
      // NOTE: I am assuming the user granted permission, here!
      CreateFolder;
    end
  );
end;

procedure TForm1.CreateFolder;
var
  fn: string;
begin
  fn := TPath.Combine(TPath.GetSharedDocumentsPath, 'OLA');
  ForceDirectories(fn);
  if TDirectory.Exists(fn) then
    Button1.Text := 'OK'
  else
    Button1.Text := 'Failed';
end;
