Normally it works the other way around... you write: {$IFDEF FPC} .... for FPC {$ENDIF} {$IFNDEF FPC} .... for DELPHI {$ENDIF} or {$IFDEF FPC} .... for FPC {$ELSE} .... for DELPHI {$ENDIF}

I am using TeeChart for drawing multiple series with two different vertical axis. One set of series uses the left axis, the others use the right axis. The legend contains check boxes that allow the user to turn a series on and off. Everything works fine but there is one small problem that I can't get solved: When all series associated with one of the axis are turned off, this axis is not shown. Right Axis missing: Left axis missing: I don't want that. Both axes should always be shown, regardless of which series are visible. But I found no way to change this behavior. Any hint?

As far as I can tell, subscriptions are yet to be supported on iOS, even in 12.2. You may be interested in this article (regarding iOS) - it was written in the Delphi 10.4 era, however the same principles may still apply.

Project Magician has an option for that:

This also happens with me all the time. There is no method to this madness. When developing with Delphi, I usually spend 10 - 15 % of my time reverting unwanted changes or being extra careful to not commit them. If you are not using any kind of version control, this is clear sign that you should start getting familiar with it now

@Der schöne Günther Please accept my apologies! @Remy Lebeau Many thanks for your wisdom here - I've learnt something new!

It is actually legal code and does compile: https://onlinegdb.com/AYf40CsUy This kind of reverse syntax is not commonly used, but it does have its uses, and the C++ standards allows it. For an array, arr[2] is the same as *(arr+2), and thus 2[arr] is the same as *(2+arr).

Which connector is used ? Firedac or ? If Firedac you can use a direct query on FDConnexion and try a EXECSQLSCALAR DatabaseId :=FDConnection1.execSQLScalar(SQL,[ADatabase.Name,Adatabase.Filename,ADatabase.FilePath, ADatabase.Description,Now]); Checked, using @emileverh remark about autoincrement

Keep it simple - create a class helper for TMemo and add an Assign method and just set the props you need. This will be quicker and easier than messing with RTTI (which can be a bit of a rabbit hole with some property types).

According the code, they're supported on at least Android. Check the FMX.InAppPurchase.Android unit. Not sure about iOS. The current implementation for Android was updated after that article was written.

Read the help topics and use the events not some Sleep/ProcessMessages messages loop. Using the iOS In-App Purchase Service - RAD Studio (embarcadero.com) Using the Google Play In-app Billing Service - RAD Studio (embarcadero.com) There is also a demo that includes in app purchases: FMX.CapitalIAP Sample - RAD Studio Code Examples (embarcadero.com)
