- 1. v2.00 Features
- ---------------
-
- For a complete list of changes in 2.00, please see Version History in
- TADBMRO.WRI. Here are some highlights:
-
- * Full support of Delphi 2.0
- * TDBLookupComboBox support added
- * TDBLookupListBox support added
- * Compatible with Orpheus v2.0
- * Compatible with InfoPower v1.2
-
-
- 2. Demo Project MROPROJ1
- -------------------------
-
- Try running the updated demo and see what 2.00 can do! Please note that any
- visual inconsistancies within the selected record are not caused by TtaDBMRO.
- Instead, this is simply how Borland programmed them. TtaDBMRO faithfully
- duplicates them. These inconsistancies are most apparent on the tab labeled
- 'Lookups, CheckBoxes, ...' when Enabled is unchecked.
-
- MROPROJ1 uses a lot of system resources, so don't try running it with many
- other applications running. If you have trouble running it directly from
- the Delphi IDE, try just compiling it, then close the project (but leave
- Delphi running if you are using the Trial Run version), and then run MROPROJ1
- from File Manager (or equivalent).
-
- For registered users, if you try to compile MROPROJ1 and you have enabled
- support for third party products, be sure you have the latest version of
- the third party software.
-
- The demo has one known problem: when toggling the Ctl3D property of
- TDBLookupComboPlus the control frequently fails to display it's contents and
- may generate an index exception (this is a problem with the component
- itself, not taDBMRO). Toggling BorderStyle after toggling Ctl3D usually
- fixes the problem. This problem can occur with TDBLookupCombo as well.
-
- TDBLookupComboPlus also mis-positions it's drop down button under WinNT.
- This, along with the aforementioned problem, are due to be fixed in its
- next release.
-
- 3. Known Problems
- ------------------
-
- There is one known cosmetic bugs regarding the cursor shape when over
- nonselected records: The cursor does not assume the crIBeam shape over
- TDBComboBox fields in Windows 3.1 (WinNT and Win95 work fine).
-
- There is one functional bug: clicking on the scroll bar of a TDBMemo field in
- a nonselected record will not scroll the contents of the field, it only gives
- the field the focus. Subsequent clicks work normally.
-
- TtaDBMRO also does not support any of the TDBLookupList.Options settings
- (loColLines, loRowLines, loTitles) and it only supports a single LookupDisplay
- field.
-
- 4. Memory Leaks
- ----------------
-
- If TtaDBMRO descends from TDBGrid (which is the case most of time unless you
- are using the InfoPower option), then there is a memory leak because
- TDBGrid.Destroy does not call FTitleFont.Free. If you have the VCL source
- code, you can apply this patch and resolve the problem.
-
-
- 5. Trial Run Users & TADBMRO.INC
- ---------------------------------
-
- Trial run users should not make any changes to TADBMRO.INC.
