  1. Make DAC errorors more clear

    When an exception is thrown by a DAC product during startup of a project - like some SQL code cant execute, then the error code wont show what form and what object created the object. If I have project with 20 forms and hundreds of MyQuerys the errr "IdObject does not exist" is not very helpfoul.

    When working with DevExpress VCL Tools the Append and Insert are different, and no im forced to use Insert instead of Append in the CX grid because the append have no corresponding event in Unidac, i cant catch it. The insert and append behaves different in the CX grid.

  6. Make it possible to combine the Sqlite3 source code and header files with LiteDAC in the same project

    Simply add #ifndef SQLITE3H_ in e.g. LiteCall.hpp.

    The location is around line 460:
    //-- var, const, procedure ---------------------------------------------------

    define DACProductName L"LiteDAC"

    define SQLiteDLLName L"sqlite3.dll"

    ifndef SQLITE3H_

    static const System::Int8 SQLITEOK = System::Int8(0x0);
    static const System::Int8 SQLITE    ERROR = System::Int8(0x1);

  8. Support non-blocking queries for MySQL in MyDAC or UniDAC

    As many DB applications support multiple threads, we could benefit from non blocking MySQL queries. Of course we know that MySQL's C connector does not currently support asynch queries; At least not documented.

  11. Add a way to turn off active sorting without losing the current sort order (ODAC lost this feature.)

    ODAC has always allowed clearing IndexFieldNames without reverting to the original sort order. The ability to sort a dataset and then turn off active sorting is very useful (and necessary for editing a sorted dataset in a grid component.)

  15. TMSTableData Assign function not copy the data

    The TMSTableData Component Assign function only copy the source table fields, but not copy the source data! I strongly recommend that can copy the all data like the TMSTable component.
    for example:
    self.MSTable1.First;
    self.MSTableData1.Close;
    self.MSTableData1.FieldDefs.Clear();
    self.MSTableData1.Assign(self.MSTable1);
    self.MSTableData1.Active:= true;

    The MSTableData1 not copy the MSTable1 data , but it copy the fields

  17. Install directories

    You guys use several uncommon directories for 3rd party components : 1: windows\System32 for some BPL
    2: Delphi\Lib for some dcp
    3: Delphi\Bin for some other BPL
    4: UniDAC for dcu

    How about using
    BDSCommon\BPL for all bpl
    BDSCommon\DCP for all dcp
    leaving the dcu in the lib of the unidac install directory

    To explain : As a developer i work with several virtual PCs that I have to update. I use a local SVN for that. Installing unidac is always a hassle because after the install I first have to copy everything where it's supposed to be and then…
