  1. Dear Sirs, in my Delphi 10.4 Form1 there are: ADOConnection1, ADOQuery1, DataSource1, DBGrid1 (TDBGrid component) and ADOConnection2, ADOQuery2, DataSource2, DBGrid2 (TDBGrid component). I use ADOConnection1, ADOQuery1, DataSource1 for polupate DBGrid1 and the other ones for populate DBGrid2. ADOConnection1 and 2 use the same access database (DB1.accdb). I would like to filter the DBGrid2 records using the selection of one record over the DBGrid1. The filter must use a Field of the selectd record (row) in DBGrid1. Questions: Is it possible and Is the correct approach? It would be preferable to create the connection to the database and manage it via code (runtime) without using components on the form (ADOConnection, ADOQuery, etc)? Is it necessary to use two adoconnections if the database to which they are connected is the same? Thanks!
  2. Few months ago I prepared small demo application used FireDAC SQLite connection on an Android system. And it worked fine in an application built in Delphi 10.3. Then I updated Delphi to 10.4. And now I got: Project xxx.apk raised exception class ESQLiteNativeException with message ''. and after that: [FireDAC][Phys][SQLite] ERROR: no such table: items. Even table 'items' exists in the database file and I did not any changes in sources. Anyone had the same issue?
  3. Hi, just for you guys to weigh in, we have located a bug in the Delphi 10.4 compiler, that removes a totally valid assign statement in RELEASE mode, believing, that the code will never be executed. The actual method is from the mORMot library in releases before last week (unit SynCommons.pas, method TSynAnsiFixedWidth.AnsiBufferToUTF8. A full discussion is available at the mORMot-Forum: https://synopse.info/forum/viewtopic.php?id=5520 . I have reported the bug to Embarcadero: https://quality.embarcadero.com/browse/RSP-30088 . Please check out my report and try to confirm and weigh in there. It should be reproducible. --- Note, the compiler will tell you (Hint H2077), that the value assigned is never used and thus, in RELEASE mode, with optimizations enabled, drop the code completely. Thanks for your time and support 👍
