shineworld 73 Posted March 6, 2022 Hi all. There is a way to detect if compile phase is in Delphi 10.4.1 or 10.4.2 ? At Embarcadero documentation they notice only VER340 and compiler 34.0 for either: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Compiler_Versions but VCL from 10.4.1 and 10.4.2 is different and in 10.4.1 NumberBox is not available. This block 10.4.1 users to compile PythonVCL design package or force them, at any pull, to manually remove any reference to NumberBox where present in check: {$IFDEF DELPHI10_4_OR_HIGHER} ... {$ENDIF DELPHI10_4_OR_HIGHER}.
