Some questions about UniDAC

Post by burdian » Thu 20 Nov 2008 10:26

Because no answer from support I will repeate this here.
I need answer because I must soon decide.

I'm already owner of IBDAC licence and decided to test UniDAC because I
need to support other DB also.

When testing I have found some problems:

1. TUniConnection.KeepDesignConnected=False (doesn't work
because Connection stayed active when IDE reopened)

2. Oracle and Interbase provider
When using Query (QueryRecCount=False) with standard DBGrid I see
Sometimes vertical scroll bar is not visible (try refresh several times and you will se change).
To test this properly you need to have a table with 50 and more records
(more then it can load in Grid buffer)
Strange thing is that there is no such problem when using MSSQL.

3. Query with UniDirectional=True using with DevExpress Grid (
DataController.GridMode=False)
In this case Grid has only last records from table (25 records only) !?
With Interbase provider after open I get Assertion failure: MemData.pas Line 2607.
DevExpress Grid works well with other UniDirectional datasets (I have used some).

Is this known probles, is it possible to expect fixes for this problems in near future?

TIA and Best regards

The KeepDesignConnected property intended not to open connection at run time if you set the Connected property at design time.

We are working on the problems 2 and 3. You will be notified when we fix the problems.
