Is there an Indy example for OAuth v2 on Android or iOS? Is there an example how to handle this?

How do you login to a site that uses OAuthV2? Is there a way to get the callback from OAuthV2?

I get warning after I uploaded AAB file to Android PlayStore with: Content labeling (Accessibility). A quick search on Google doesn't reveal much. This is what I'm referring to: Content labels - Android Accessibility Help

Does ICS v9.3 support Android x64 or Android 32-bit? I get this error. Cannot load libcrypto.3.dynlib First chance exception at $000000799476004C. Exception class EIcsLibeayException with message 'Failed to load OpenSSL file libcrypto.3.dylib - Handle 0'.

I operate a small business doing Delphi coding and work-for-hire. My services are: App modernization, legacy upgrades. From Delphi 1 (Windows 3.1) to Delphi XE 12.1 See: Case Studies I’ve personally developed on C++ UI components, newer Delphi Skia-based components. New application development (UI work, coding). You can choose from different team options: Dedicated team - need a team? Staff augmentation (developers on-and-off basis), Outsourcing (such as, 3 hours a week, Once a month to update Delphi app) What you get: Full source-code in Github/ Gitlab/ BitBucket / Azure repository. CI/CD build (where applicable), so when there's check-in, a build is made. Markdown documented and unit tested code. Optional profiling project if code is slow. Warranty (if there's a small fix it'll get fixed). I'm top-rated on Upwork and on Embarcadero Blogs. My website and contact form.

Andy's VCL Fix Pack is a Delphi open-source unit that fixes VCL and RTL issues at runtime by patching the original functions. Andy's Unit contains easy-to-use functions to update code that cannot be easily recompiled or changed. If you try to change VCL sources (files in Source folder of your RadStudio, Delphi or C++ Builder installation) and attempt to recompile them within your project, you'll get multiple errors, such as: DCU mismatch, (file1.pas) is compiled with a newer version of (file2.pas). This occurs when source-code is compiled with a different file and needs to be fully recompiled. In the below example, I will use Andy's fix pack to fix a long standing bug - QC15408.

In the Delphi code, I did the same, create a component from TCustomControl. I add WMMouseMove windows message procedure TCustomControlButton.WMMouseMove(var Message: TWMMouseMove); begin // inherited; // how to emulate this keyword and call base class's WMMouseMove in C++ Builder? end; In C++ Builder, I am trying to build a VCL C++ Builder component. I sub-class TCustomControl. However, I cannot seem to do the same equivalent in C++ Builder. "inherited". What should I do to solve this problem? void __fastcall TCustomControlButton::WMMouseMove( Winapi::Messages::TWMMouse &Message) { // do something... TCustomControl::WMMouseMove(Message); // OR __super::WMMouseMove(Message); } I get: [bcc32c Error] something.cpp(300): 'WMMouseMove' is a private member of 'Vcl::Controls::TControl'. Vcl.Controls.hpp(1655): declared private here

Here's the distilled Delphi code: unit exampleunit; interface uses Windows, Messages, SysUtils, Classes, VCL.Graphics, VCL.Controls, VCL.Forms, VCL.Dialogs, VCL.StdCtrls, VCL.Buttons; type TExample = class(TCustomControl) protected procedure WMMouseMove(var Message: TWMMouseMove); message WM_MOUSEMOVE; end; procedure Register; implementation procedure TExample.WMMouseMove(var Message: TWMMouseMove); begin // inherited; end; procedure Register; begin RegisterComponents('Samples', [TExample]); end; end. Here's the C++ code. C++ Builder is, supposed to be the equivalent of Delphi, and should allow for C++-only VCL components. In reality, all the development goes one way. Delphi exported components to C++ Builder. Here's the C++ Builder component: //--------------------------------------------------------------------------- #ifndef examplecomponentcppH #define examplecomponentcppH //--------------------------------------------------------------------------- #include <System.Classes.hpp> #include <System.SysUtils.hpp> #include <Vcl.Controls.hpp> #include <Vcl.ExtCtrls.hpp> class PACKAGE TExampleCpp : public TCustomControl { private: protected: void WMMouseMove(TWMMouseMove Message); public: __fastcall TExampleCpp(TComponent *Owner); __fastcall virtual ~TExampleCpp(); }; #endif //--------------------------------------------------------------------------- #pragma hdrstop #include "examplecomponentcpp.h" //--------------------------------------------------------------------------- #pragma package(smart_init) __fastcall TExampleCpp::TExampleCpp(TComponent *Owner) : TCustomControl(Owner) { } __fastcall TExampleCpp::~TExampleCpp() { } void TExampleCpp::WMMouseMove(TWMMouseMove Message) { // what to put here that is equivalent of the Delphi version? TCustomControl::WMMouseMove(Message); } static inline void ValidCtrCheck(TExampleCpp *) { new TExampleCpp(NULL); } There is "inherited." It's called __super https://stackoverflow.com/questions/8326309/borland-delphi-alternative-to-super-keyword or (baseclass)::(procedure). The question is. In Delphi, the inherited keyword works and causes the code to go to a private procedure in controls.pas. This beaks the cannot call private procedures and functions compiler restriction in Delphi. Which is enforced in Delphi. In C++ Builder, it bugs out and [bcc32c Error] examplecomponentcpp.cpp(17): 'WMMouseMove' is a private member of 'Vcl::Controls::TControl' Vcl.Controls.hpp(1655): declared private here Why is inherited keyword not supported in C++ Builder? Does that mean, it becomes impossible to build components in C++ Builder? the same code that compiles and works, in Delphi, cannot be done in C++ Builder? Why is it, the same Delphi code, exports as a C++ Builder component works in C++ Builder? When you try to do the same thing in C++ Builder, it becomes impossible, or there are no code samples. > You need to call the base class Dispatch() method. Or override the virtual WndProc() method instead of using a MESSAGE_MAP Can you show a complete example?

hi, I ordered kbmMemTable with SAU a few days ago. I have emailed the vendor, he hasn't replied. Any ideas how to contact Mr. Kim?

I've been doing some simple testing.

Can I ask. Do you have the source-code for your changes you made? The source-code in this thread has only for the Sequenced, TArray.BinS, TDict and TSynDict, not Spring. For CustomBinS, the hash routine often access violation 'out of range' and not suitable for larger arrays...

Hi, http://www.overbyte.eu/ is down. I cannot download ICS. Please advise if they have mirror location(s).

Does anyone have an update for this, i.e., login to Google, login to Facebook in Android and iOS platform?

I would like to use BackBlaze S3-compatible API. How would I use BackBlaze S3-Compatible API with Delphi?

Let's say you have a set of repeat numbers: TDictionary<integer1, TDicationary<integer2, integer3>> [1, [2, 1]] [1, [1, 2]] [1, [1, 3]] (huge... like 30000) [2, [2, 1]] [2, [1, 2]] [2, [1, 3]] ... [3, [2, 1]] [3, [1, 2]] [3, [1, 3]] What would be a fast way to select all numbers with [x, [x, 1]], then [x, [x, 2]] ? I do a loop but there must be a faster way than loop the loop.

I have question. I need a data structure that looks like this: DataStructure<TKey1, TKey2, TValue, TPayLoad> Where - there the data is sorted by 2 keys. - the value can be any (e.g., integer, string). - there is a ternary Payload which stores non-sorted data. I want to the data to have 2 primary key indexes, TKey1 or TKey2. I query TKey1 = '1', I get all values of (TKey1 = 1) for the data. I query TKey2 = '2', I get all values of (TKey2 = 1) for the data. Problem. 1. I use TDictionary and THashList, Not sure how to store TKey1, TKey2, and TValue1 with TPayLoad. I could use TDictionary<TPair<TKey1, TKey2>, TPair(TValue1, TPayload>); - how to search by partial, where I special only one part of TPair? 2. I tried TObjectList, I cannot order by TKey2, just TKey1 and store everything inside an Object. It gets slow trying to do filtered-search and retrieve filtered by TKey1 or TKey2. 3. I tried TList, but I want to get an order by TKey1 and TKey2, I need to keep sorting it as often. 4. I need to keep TKey1, TKey2 as ordered lists to quickly index/query TValue. Any ideas?

I tried. Does anyone else have any suggestions? I think a B*Tree would work since Key1, PayLoad can be searched quickly

I need a 64-bit version of himXML https://www.delphipraxis.net/130751-himxml-gesprochen-himix-ml.html This was last updated in: himxml_164.7z = v0.99d 12.01.2010 Any ideas how to get this?

I asked. Thanks... I switched to https://blog.spreendigital.de/2014/09/13/verysimplexml-2-0/

okay, problem solved. Mr. Kim came online.

I'd like to ask if there's an alternative to kbmMemTable, in terms of ease of use, and/or ability to copy an existing TDataSet.
