Hello, Dave Thanks for the demo project. Is there a more universal way to view the list of files in Android folders? Regarding the TDirectory.GetDirectories(), TDirectory.GetFiles() methods, I noticed that the TDirectory.GetDirectories('/storage/emulated/0/') method returns a list of folders similar to what is visible in the Files by Google program. Files by Google displays files in folders such as: '/storage/emulated/0/DCIM/Camera' '/storage/emulated/0/DCIM/Screenshots' '/storage/emulated/0/Documents' '/storage/emulated/0/Download' but the TDirectory.GetFiles() method does not return any files when specifying any path. What method should be used in Android to get a list of files in a folder?

Is there a Demo project in RAD Studio Samples or on github.com that demonstrates the ability to view photos in the app taken via the camera? Perhaps the TDirectory.GetFile method on Android does not work correctly or the app should request some rights via User Persmissions.

TPath.GetCameraPath() returns the following value - '/storage/emulated/0/Android/data/com.embarcadero.EhLib_Fmx_MainDemo/files/DCIM'. When viewing from the program via TDirectory.GetFile, this folder does not contain files. When viewing from the phone, I cannot access the folder ‘/storage/emulated/0/Android/data/com.embarcadero.EhLib_Fmx_MainDemo’ at all.

Good day. Embarcadero® RAD Studio 12 Version 29.0.55362.2017 Android 13, Samsung S20. I have files taken by the camera in the folder '/storage/emulated/0/DCIM/Camera' on my phone. How to set up the Android application correctly so that I can get a list of these files? When creating an Fmx application by default, the command TDirectory.GetFiles('/storage/emulated/0/DCIM/Camera') returns an empty list.

Class alias for class helper doesn't make class helper visible for compiler. Is it possible to declare class alias for class helper with making class helper visible for compiler? Example Unit1 TControlHelper = class helper for TControl function RefSelf: TControl; end; Unit2 TControlHelper = Unit1.TControlHelper; Unit3 uses Unit2; ... var MyControl: TControl; MyControl.RefSelf //Compiler error.

Thank you. This code works: TListFieldLinkListEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListFieldLinkListEh<T>); TTypedListItemLinkEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TTypedListItemLinkEh<T>); TListRecLinkListEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListRecLinkListEh<T>); TListTableLinkEh<T: class, constructor> = class(EhLib.TableLink.TypedLists.TListTableLinkEh<T>); In this case, however, a new type is created. But for types created through generics this is not a very big problem.

Is it possible to declare an identical type for a generic class? I can't do it. TTypedListFieldLinkEh = EhLib.TableLink.TypedLists.TTypedListFieldLinkEh; TListFieldLinkListEh = EhLib.TableLink.TypedLists.TListFieldLinkListEh; TTypedListItemLinkEh = EhLib.TableLink.TypedLists.TTypedListItemLinkEh; TListRecLinkListEh = EhLib.TableLink.TypedLists.TListRecLinkListEh; TListTableLinkEh = EhLib.TableLink.TypedLists.TListTableLinkEh; TListFieldLinkListEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListFieldLinkListEh<T: class, constructor>; //Compile Error TTypedListItemLinkEh<T: class, constructor> = EhLib.TableLink.TypedLists.TTypedListItemLinkEh<T: class, constructor>; TListRecLinkListEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListRecLinkListEh<T: class, constructor>; TListTableLinkEh<T: class, constructor> = EhLib.TableLink.TypedLists.TListTableLinkEh<T: class, constructor>;

Hello. I would like to thank you for supporting GExperts. I am using GExperts_RS12_1.3.25_2024-08-24.exe in RAD Studio 12.3. I use only three functions: SortLines, PreviousIdent, NextIdent. These functions work in RAD Studio 12.3 without errors.

Hello. The following code takes 0.1 seconds on my computer. In my opinion, this is too slow. procedure TFormSimpleDraw2.Button4Click(Sender: TObject); var ItfcVarValue: TValue; Itfc: IInterface; VarValue: Variant; Res: Boolean; begin Itfc := TInterfacedObject.Create; VarValue := Itfc; ItfcVarValue := TValue.From<Variant>(VarValue); var TimeSpan := TThread.GetTickCount64; Res := ItfcVarValue.IsType<String>; Memo1.Lines.Add(FloatToStr((TThread.GetTickCount64 - TimeSpan) / 1000) + ' sec; Result = ' + Res.ToString(TUseBoolStrs.True)); end; Result in Memo1 Memo1.Text = 0.109 sec; Result = False Most likely the reason is related to the occurrence of an internal exception which is then suppressed somewhere. ---- procedure TFormSimpleDraw2.Button5Click(Sender: TObject); var Res: Boolean; ItfcVarValue: TValue; begin ItfcVarValue := TValue.From<IInterface>(TInterfacedObject.Create); var TimeSpan := TThread.GetTickCount64; Res := ItfcVarValue.IsType<String>; Memo1.Lines.Add(FloatToStr((TThread.GetTickCount64 - TimeSpan) / 1000) + ' sec; Result = ' + Res.ToString(TUseBoolStrs.True)); end; Memo1.Text = 0 sec; Result = False

Since I only use dynamic arrays I used the following solution: function ValueIsArrayOfValues(const V: TValue): Boolean; begin Result := V.TypeInfo = TypeInfo(TArray<TValue>); end;

I think like this: function ValueIsValueArray(const V: TValue): Boolean; begin Result := (V.TypeInfo <> nil) and (V.TypeInfo^.Kind in [tkArray, tkDynArray]); if Result then Result := (V.TypeData^.ArrayData.ElType = TypeInfo(TValue)); end;

Hello How to check that TValue.Type is array of TValue function ValueIsValueArray(const V: TValue): Boolean; begin Result := V.TypeInfo = System.TypeInfo(array of TValue); //?? end;

Good day. I have Embarcadero® RAD Studio 12 Version 29.0.53982.0329 Tell me how to work with the FMX.WebBrowser.TWebBrowser component correctly I drop TWebBrowser on the Form. The code is written procedure TMainForm.Button1Click(Sender: TObject); begin WebBrowser.Navigate('https://getbootstrap.com/docs/5.3/getting-started/introduction/'); end; and as a result I get the following picture: It looks like the browser is not processing the css and aside section of the page.
