BDEDemoServer and Delphi XE3 (exception in "rtcDB.pas" unit)

[Wolfgang]

Starting from Line 879 in procedure DelphiDataSetToRtc(DelphiDS: TDataSet; rtcDS: TRtcDataSet;

Field := DelphiDS.FindField(fldname);
      if assigned(Field) then
        if not Field.isNull then
          if (OnlyDataFields = False) or (Field.FieldKind = fkData) then
            if Field.isBlob then
            begin
              FStream := DelphiDS.CreateBlobStream(Field, bmRead);  --------------->> Returns error is not a blobfield for ftMemo

Kind Regards

I'm afraid the BDE implementation in Delphi XE3 is broken. The problem is not only with ftMemo fields, but any kind of a BLOB field (like ftGraphic). Here is a topic on Embarcadero Forums about the BDE, BLOB fields and Delphi XE3:

While I don't have a solution for getting the BDEDemoServer to work on Delphi XE3 without fixing the BDE units, I think the BDEDemoServer can still serve its purpose, because you can use it as a starting point when writing your own Server using a Database Engine of your choice (I'm guessing it won't be the BDE). If you get stuck, please let me know.

Having seen some other people complain,I suspected as much.

Thanks Danijel

Installing RAD Studio XE3 Update 1 fixes 4 bugs from the BDE, including the one that was causing this exception (QC Report #108660):
