E2003 Undeclared identifier: 'TRtcMemDataSet' in iOS Delphi XE4

[wbroyles]

I get and E2003 Undeclared identifier: 'TRtcMemDataSet' error trying to build a iOS app in XE4 using RTC 6.20. I don't get the error when I target win32. Is TRtcMemDataSet working in iOS targets?


Thanks

Sorry, but the TRtcMemDataSet class was NOT ported to the NextGen compiler. The only suggestion I can make at this point, is to use another in-memory DataSet (like TClientDataSet). You can connect it to the TRtcDataSetMonitor if you need to track changes.

Danijel,

What is the best method to convert Result.asDataSet to TClientDataSet?

Check RtcDataSetFieldsToDelphi and RtcDataSetRowsToDelphi procedures from the rtcDB unit.

Danijel,

Thanks!

PS - The TRtcMemDataSet shows active in the component palette when you select iOS as a target and is in the quick help target list when you mouse over the component in the component palette. The source of my confusion.

Sorry for the confusion. I will try to make the "NextGen" version of the TRtcMemDataSet class shortly after Delphi XE5 is released, together with Android platform support. I hope Embarcadero will have completed making breaking changes to their TDataSet class by then.

Hi Danijel,

At the time you modify TRtcMemDataset for XE5, I suggest to add some more function like .asText['fld'], .asDateTime['fld'], .asInteger['fld'], .asCurrency['fld'] (came from FieldByName('fld').AsString, .. ). This will comply to TRtcValue style.

Is it possible?

TIA and Best Regards,

You already have access to the internal TRtcDataSet object though the "asDataSet" property of the TRtcMemDataSet component.
