Have you tried to use lower resolution and turn the light on?

I have seen the same problem and have "solved" it this way: Kamera.Quality := FMX.Media.TVideoCaptureQuality.LowQuality; Kamera.Quality := FMX.Media.TVideoCaptureQuality.MediumQuality;

The declaration must be outside of the form...

Did you read, what Cristian Peța linked? function ShutdownBlockReasonCreate(hWnd: HWND; Reason: LPCWSTR): Bool; stdcall; external user32; function ShutdownBlockReasonDestroy(hWnd: HWND): Bool; stdcall; external user32;

I believe Anders is right. Class reference is just a pointer - its size is known. When you use this class as a member of another class (fChild: tChild, where tChild is a class), you cannot reference its members in properties (property x: integer read fChild.x). If fChild is a record (fChild: tChild, where tChild is a record), you can reference its members in properties, like in Anders' example (property x: integer read fChild.x).

If size was the only problem, I can imagine something like this ("human preprocessor"): type tRecordA = record of size 8; tRecordB = record ... function Test: tRecordA; end; tRecordA = record x, y: integer; end;

Something like a record helper 🙂 I always wonder why there can be just one class/record helper...

Or NativeInt(pointer(... or NativeUInt(pointer(... Just when I see this typecasting pointer to integer, I can't help thinking that 64 bit IDE is far away 🙂

64 bit IDE would probably require all design time packages to be 64 bit, too... I was surprised to see typecast "integer(pointer(..." in https://blog.marcocantu.com/blog/2020-may-custom-managed-records.html ...

With this info in mind, for bad customers you can start programming like that: const _ = 1; _____ = 2; x = _____ + (_-_-_) + 0 + _+0-0+_ ;

May be https://github.com/neslib/FastMath and/or http://docwiki.embarcadero.com/RADStudio/Rio/en/Floating_point_precision_control_(Delphi_for_x64) can help.

Hello, Please can you advise a profiler for Win32/Win64 applications (made in Delphi)? Free, when possible (I do not need the profiler often). What I have found using Google was expensive or quite outdated or buggy. Kind regards, Karel

tDictionary alone will not allow you to store more values for the same key (it seems you need it: "I get all values of (TKey1 = 1) for the data. "). You could use two dictionaries: tDictionary<tKey1, tObjectList> tDictionary<tKey2, tObjectList> In these object lists, there will be all objects with corresponding values of the tKey1, resp. tKey2.

It happens to me +- once every two weeks, too.

Sorry, I did not read carrefully the title.

You mean something like this? type tSledovaniVykonuSeznamVysledku=class(tObjectList<tSledovaniVykonuVysledky>) ... var Cmp: IComparer<tSledovaniVykonuVysledky>; begin Cmp:=tDelegatedComparer<tSledovaniVykonuVysledky>.Create( function(const Left, Right: tSledovaniVykonuVysledky): Integer begin result:=CompareStr(Left.Nazev, Right.Nazev); end); Sort(Cmp);

Thank you, AsmProfiler suites the best.

I have just tried to download it using Chrome (Czech version 81.0.4044.122 (Oficiální sestavení) (64bitový) ), downloaded without problems, browser allowed me to start the downloaded .exe.

What about remote debugging?

This compiles, but I have not tested, whether it works as expected 🙂 ToField<T> = class(tObject) private fData : T; protected procedure SetFromVariant(const aValue : Variant); end; procedure ToField<T>.SetFromVariant(const aValue: Variant); var val: TValue; begin val := TValue.FromVariant(aValue); fData := val.AsType<T>; end;

Do you have an idea, how many users really need new functions for old versions of Delphi? If there are not many of them, I would suggest to drop support for old versions - you can probably spend your time better than keeping code compatible with old Delphi...

Probably the same problem as in Project Window https://quality.embarcadero.com/browse/RSP-27182 It is reported, but when it will be fixed...

What about DirectWrite? It should support OpenType fonts.

Does AV happen on one computer, or all? Every query, or just some (with parameters? with string result? with only integer result? etc.)?

But he wrote that error happens in external .dll when he opens a query, not in his code.
