Why uploaded photo is much smaller than saved – Delphi 10.3.2, firemonkey

I have Delphi 10.3.2 I do not understand this situations: 1) Uploading photo about 1M image1.Bitmap.LoadFromFile('test.jpg'); Then I save the same photo image1.Bitmap.SaveToFile('test_new.jpg'); and test_new.jpg is about 3M. Why ??? 2) I want to send a photo from the TImage (test1.jpg - 1MB) object using IdHTTP and POST request to server. I use the function Base64_Encoding_stream to encode image. Image size (string) after encoding the function is 20 MB! ? Why if the original file has 1MB ? function Base64_Encoding_stream(_image:Timage): string; var base64: TIdEncoderMIME; output: string; stream_image : TStream; begin try begin base64 := TIdEncoderMIME.Create(nil); stream_image := TMemoryStream.Create; _image.Bitmap.SaveToStream(stream_image); stream_image.Position := 0; output := TIdEncoderMIME.EncodeStream(stream_image); stream_image.Free; base64.Free; if not(output = '') then begin Result := output; end else begin Result := 'Error'; end; end; except begin Result := 'Error' end; end; end; .... img_encoded := Base64_Encoding_stream(Image1); ..... procedure Send(_json:String ); var lHTTP : TIdHTTP; PostData : TStringList; begin PostData := TStringList.Create; lHTTP := TIdHTTP.Create(nil); try PostData.Add('dane=' + _json ); lHTTP.Request.UserAgent := 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0'; lHTTP.Request.Connection := 'keep-alive'; lHTTP.Request.ContentType := 'application/x-www-form-urlencoded'; lHTTP.Request.Charset := 'utf-8'; lHTTP.Request.Method := 'POST'; _dane := lHTTP.Post('http://......./add_photo.php',PostData); finally lHTTP.Free; PostData.Free; end;

Problem displaying items in Listbox and Memo in Firemonkey Android application

I am at my first experiences with Android development using Delphi/Firemonkey 10.3.1 and have encountered the following problem with populating and displaying items in a TListbox component and a TMenu component at run time. I have placed TListbox and TMenu components on a panel, together with a button to trigger the generation of a sequence of random numbers and display them in these components. The TListbox component contains objects of class TListboxItemRandomNo descending from TListboxItem. The code for this class is: TListboxItemRandomNo= class(TListboxItem) private FRandomNo: integer; {Number displayed by Listbox item} protected procedure HandlePaint(Sender: TObject; Canvas: TCanvas; const ARect: TRectF); function GetItemText: string; public constructor Create(Owner: TComponent; RandomNoValue: integer); property RandomNo: integer read FRandomNo; end; constructor TListboxItemRandomNo.Create(Owner: TComponent; RandomNoValue: integer); var Listbox: TListbox; begin Listbox:= Owner as TListbox; inherited Create(Owner); Listbox.AddObject(Self); {Save RandonNo:} FRandomNo:= RandomNoValue; {Assign OnPaint event handler:} OnPaint:= HandlePaint; end; procedure TListboxItemRandomNo.HandlePaint(Sender: TObject; Canvas: TCanvas; const ARect: TRectF); var Text: string; TextSize: TSizeF; TextPosn: TPointF; TextRect: TRectF; begin {Calculate item text:} Text:= GetItemText; {Set colour for text:} Canvas.Fill.Color:= TAlphaColorRec.Black; {Determine text image size, position and bounding rectangle:} Canvas.TextWidth(Text); Canvas.TextHeight(Text); TextPosn.x:= ARect.Left + 5; TextPosn.y:= (ARect.Top + ARect.Bottom -; TextRect.TopLeft:= TextPosn; TextRect.Right:= ARect.Right; TextRect.Bottom:= TextRect.Top +; {Draw item text:} Canvas.FillText(TextRect, Text, False, 1.0, [], TTextAlign.Leading, TTextAlign.Center); end; function TListboxItemRandomNo.GetItemText: string; begin Result:= IntToStr(Index) + ': ' + IntToStr(FRandomNo); end; Initially I put the code to generate and display the random numbers in the OnClick event handler of the button. Whilst this approach worked on the Windows 32-bit platform, on the Android platform in both the TListbox and the TMemo components the items were not displayed. I then created an Action called ActionCalcRandomNos and moved the code to generate and display the random numbers from the button’s OnClick event handler into the OnExecute event handler of the action. I disconnected the OnClick event handler of the button and assigned ActionCalcRandomNos to it instead. After these changes I found that the items in both the TListbox and the TMemo components were displayed on both the Windows-32 and the Android platforms. The code in question is: procedure TForm1.ActionCalcRandomNosExecute(Sender: TObject); {Calculates a random sequence of numbers and displays them in TListbox and TMemo components} var i: integer; xi: integer; ListboxItemRandomNo: TListboxItemRandomNo; LineI: string; begin {Read number of random numbers required:} FRandomNoCount:= StrToInt(EditItemCount.Text); SetLength(FRandomNoSequence, FRandomNoCount); {Generate random number sequence:} Randomize; for i := 0 to FRandomNoCount-1 do begin xi:= Random(FRandomNoCount); FRandomNoSequence[i]:= xi; end; {Generate Listbox items dislaying random numbers:} ListBoxRandomSequence.Clear; ListBoxRandomSequence.BeginUpdate; for i:= 0 to FRandomNoCount-1 do begin ListboxItemRandomNo:= TListboxItemRandomNo.Create(ListBoxRandomSequence, FRandomNoSequence[i]); end; ListBoxRandomSequence.EndUpdate; {Write random numbers to TMemo:} MemoRandomNos.Lines.Clear; MemoRandomNos.BeginUpdate; for i:= 0 to FRandomNoCount-1 do begin LineI:= (ListBoxRandomSequence.ListItems[i] as TListboxItemRandomNo).GetItemText; MemoRandomNos.Lines.Add(LineI); end; MemoRandomNos.EndUpdate; end; Why did this code not work when called directly from the button OnClick event handler, but did work when called indirectly via the action ActionCalcRandomNos connected to the button? The only remaining minor problem with the TListbox is this. The item height, which is set as 0 in the Object Inspector, on the Android platform version only is being displayed much too great. This started after I changed the ItemHeight property back to 0 after previously having set it at 20. Any light shed on any of these problems would be helpful.

Why isn’t InputQuery returning bool?

I've followed the clear documentation to implement an input dialog box. It works fine. But, now i want to ignore the user input if they click cancel. Below is quote from that documentation. "If the user clicks the OK button, InputQuery returns True; InputQuery returns False otherwise." So, i tried the following code and the error i'm getting is E2034 Cannot convert void to bool when i run on Win32 and bccaarm error 1711 value of type void is not contextually convertible to bool on Android. if (InputQuery(caption, Prompts, sizeof(Prompts)/sizeof(Prompts[0]) - 1, Defaults, sizeof(Defaults)/sizeof(Defaults[0]) - 1, (TInputCloseQueryProc *)Met)){ // clicked OK } else { // clicked cancel } How can i test if OK or Cancel clicked? Below is the declaration for InputQuery and it should be bool. I'm confused. extern DELPHI_PACKAGE bool __fastcall InputQuery _DEPRECATED_ATTRIBUTE1("Use FMX.DialogService methods") (const System::UnicodeString ACaption, const System::UnicodeString *APrompts, const int APrompts_High, System::UnicodeString *AValues, const int AValues_High, const _di_TInputCloseQueryFunc ACloseQueryFunc = _di_TInputCloseQueryFunc())/* overload */;

Using the GetClass function with VCL / FMX not found

I have the following situation, project in *.bpl VCL structure. I want to adapt a screen made in FMX in this structure using LoadPackage and GetClass.

When I run form VCL after running FMX it loses reference in the GetClass function. But it can return the address that was allocated in the LoadPackage function. I couldn’t see what might be going on.

Hardware Locked Licensing Delphi RIO

i want my user to use my software only in one system or login once at a time for that i want to know how can i create such keys that's effected by changes in other hardware. I am using that key to check in server and return true if the key generated by user hardware is same as key stored at first login from my desktop app. and at logout i am deleting that key from server and saving the key which will be fetched from next login hardware.. I've read all the related question but they are useless when any part of hardware is changed(such as hdd changed). and i know that this thing is not 100%. Is key based on bios is good alternative to hdd cpu and other components as they may change anytime ? i found this for delphi but this is way back updated and supported in windows 7 don't know about Windows 10.

Restrict user input to digits only with InputQuery

I've followed the Embarcadero documentation to provide an input dialog to let user give keyboard input (I followed the C++ example exactly). I know this is implemented with TEdit boxes internally, is it possible to restrict user input in the dialog to digits only (0-9)? I'm thinking something like we can do with regular TEdit boxes using the FilterChar property or somehow specify the KeyboardType property to NumberPad.

Inaccessible value from control on embedded child form (Delphi, Firemonkey)

I am new to Firemonkey (using RadStudio 10.3.2), and I am trying to update a listbox control on an embedded child form. However, when I try to access any of the properties of the listbox (ListBox1), they show up as "Inaccessible value." I'm pretty sure that I am missing something very simple. I appreciate any and all help! Thank you! I have made the following, simplified application, to illustrate my issue. Project1 Application Initialization: program Project1; uses System.StartUpCopy, FMX.Forms, Unit1 in 'Unit1.pas' {Form1}, Unit2 in 'Unit2.pas' {Form2}; {$R *.res} begin Application.Initialize; Application.CreateForm(TForm1, Form1); Application.Run; end. Unit1.pas: unit Unit1; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.Controls.Presentation, FMX.StdCtrls; type TForm1 = class(TForm) Panel1: TPanel; Button1: TButton; procedure FormCreate(Sender: TObject); procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } procedure EmbedForm(AParent:TControl; AForm:TCustomForm); end; var Form1: TForm1; implementation {$R *.fmx} uses Unit2; procedure TForm1.FormCreate(Sender: TObject); begin // Embed Scenarios Form EmbedForm(Panel1, TForm2.Create(Self)); Panel1.Visible := true; end; procedure TForm1.Button1Click(Sender: TObject); var data_strings: array of string; begin // Assign strings SetLength(data_strings, 2); data_strings[0] := 'Hello'; data_strings[1] := 'World'; // Load strings Form2.ListBox1.Items.Add(data_strings[0]); Form2.ListBox1.Items.Add(data_strings[1]); end; procedure TForm1.EmbedForm(AParent: TControl; AForm: TCustomForm); begin while AForm.ChildrenCount>0 do AForm.Children[0].Parent:=AParent; end; end. Unit2.pas: unit Unit2; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.Layouts, FMX.ListBox; type TForm2 = class(TForm) ListBox1: TListBox; private { Private declarations } public { Public declarations } end; var Form2: TForm2; implementation {$R *.fmx} end. The Form2.ListBox1 properties are inaccessable to the code on the main form--see the Button1Click event. I have the parent form (Unit1) using the child form (Unit2). I am at a loss as to why an enabled, visible component is inaccessible. My modal forms never had this issue, so I think it has to do with the embedded child form.

Open PDF file Delphi RIO

I would like to open a PDF that is allocated locally in my application (ANDROID only), but I am not getting it at all.

I already tried this link: Getting exception while opening PDF file for Android 26 using Firemonkey/Delphi but not work in Delphi RIO.

So I kept looking and got this code:

procedure TF_NovaART.PRO_MapeaClick(Sender: TObject);
  fName       : String;
  LIntent: JIntent;
  LAuthority: JString;
  LUri: Jnet_Uri;
    fName := TPath.GetDocumentsPath + PathDelim + 'PRO_Topo.pdf';

      LAuthority := StringToJString(JStringToString(TAndroidHelper.Context.getApplicationContext.getPackageName) + '.fileprovider');
      LUri := TJFileProvider.JavaClass.getUriForFile(TAndroidHelper.Context, LAuthority, TJFile.JavaClass.init(StringToJString(fName)));
      LIntent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW);
      LIntent.setDataAndType(LUri, StringToJString('application/pdf'));



Which was found on this link: Getting exception while opening PDF file for Android 26 using Firemonkey/Delphi

I did exactly as it is written, but returns me the following error:

now it’s giving :

I think I need to put in the “AndroidManifest”, but I’ve already researched it and I’m not sure how to set it. (This bug has been stalking me for over a month. I skipped this part of the code to do other things, but again I’m unable to continue because of it)

I have this interface called "IViewFrame" its implementation is like this: __interface INTERFACE_UUID("{D307ACE9-FE13-4F11-BEEB-A15C908579BC}") IViewFrame : public System::IInterface { //--------------------------------------------------------------------------- protected: //Setters/Getters virtual void __fastcall SetView(TView *Value) = 0; virtual TView* __fastcall GetView() = 0; //--------------------------------------------------------------------------- public: //Fields/Properties __property TView *View = {read = GetView, write = SetView}; //--------------------------------------------------------------------------- }; //--------------------------------------------------------------------------- typedef System::DelphiInterface<IViewFrame> _di_IViewFrame; Now on VCL this interface is working fine here is the code: class TVCLFrame : public TFrame, IViewFrame { __published: // IDE-managed Components private: //Fields TView *FView; //--------------------------------------------------------------------------- protected: //Setters/Getters virtual void __fastcall SetView(TView *Value); virtual TView* __fastcall GetView(); public: // User declarations __fastcall TVCLFrame(TComponent* Owner); INTFOBJECT_IMPL_IUNKNOWN(TFrame); }; //--------------------------------------------------------------------------- But when I do the same thing in an FMX Frame, I get a conflict error in INTFOBJECT_IMPL_IUNKNOWN: class TFmxFrame : public TFrame, IViewFrame { __published: // IDE-managed Components TBindingsList *BindingsList; TBindSourceDB *BindSourceDB; TBindNavigator *BindNavigator1; private: // User declarations TView *FView; protected: //Setters/Getters virtual void __fastcall SetView(TView *Value); virtual TView* __fastcall GetView(); public: // User declarations __fastcall TFmxFrame(TComponent* Owner); INTFOBJECT_IMPL_IUNKNOWN(TFrame); // I get the error here }; //--------------------------------------------------------------------------- [bcc32 Error] FmxFrameU.h(50): E2113 Virtual function '__stdcall TFmxFrame::Release()' conflicts with base class 'TFmxObject' Now I looked into TfmxObjct code and found out that there is another method called Release() that conflicts with the one from the IUnknown Interface. How can I fix this issue? I want this interface to work for both VCL and FMX without any troubles.

what is wrong with this use of goto?

I'm using a goto statement to skip a piece of code (as per documentation), just for testing purposes while I debug a block of code. I'm getting an error 1526, "goto into protected scope". This is totally trivial I know, but I want to know what is wrong with how I'm using the goto code: #if defined(_PLAT_ANDROID) _di_JIntent MyIntent; MyIntent = TJIntent::JavaClass->init(TJIntent::JavaClass->ACTION_VIEW, TJnet_Uri::JavaClass->parse(StringToJString(""))); TAndroidHelper::Activity->startActivity(MyIntent); goto Skipit; Androidapi::Jni::Graphicscontentviewtext::_di_JIntent intent = TJIntent::Create(); intent->setDataAndType(StringToJString("file://" + System::Ioutils::TPath::Combine(System::Ioutils::TPath::GetSharedDownloadsPath(), "sample.pdf")), StringToJString(L"application/pdf")); intent->setAction(TJIntent::JavaClass->ACTION_VIEW); intent->setFlags(TJIntent::JavaClass->FLAG_GRANT_READ_URI_PERMISSION); if (SharedActivity()->getPackageManager()->queryIntentActivities(intent, TJPackageManager::JavaClass->MATCH_DEFAULT_ONLY)->size() > 0) { SharedActivity()->startActivity(intent); } else { ShowMessage("PDF viewer not found"); } Skipit: #endif I'm working in 10.3.2 and building toward Android target.
