Hello,
(Sorry for my english)
J testing myDAC (latest 60-day trial version, 20-Jan-05 MyDAC 3.50),
Delphi 5 Proffesional +SP1, WinXP Profesional +SP2 +latest updates; and:
1. Create Form1, add myQuery1 or myConnection1 - with default settings (from myDAC pack), compile, close compiled program > all ok,
2. create (adding) new blank Form2, compile, close compiled program > all ok,
3. create (adding) new blank Form3, compile ... close .. ok,
4. create ..blank Form4 .. compile .. close > all ok,
5. create (adding) new blank Form5, compile, close compiled program > .. after closing compiled program with 5 blank forms (only on Form1 is 1 component) program crashes with errors:
1: - "Access violation at address 40003AB0 in module vcl50.bpl. Read of address 01100094. Use step or Run to continue ..."
2: Error: "Runtime error 216 at 00002F30"
3: Protection Error: Error 103.

When J use more than 4 forms with component from myDAC packs (forms autocreate or dynamics (if dynamics - when J showing this forms)) always after closing compiled program J view these 3 errors.
If use more than 4 forms without myDAC component, all ok.

It's MS SP2 new protection problem or myDAC component?
I trying find component for my application in office with mySQL 4.1 database (my application has more than 4 forms).
J testing this situation on 2 different (hardware) computers (Windows XP SP2 and Delphi 5 Proff Add1 versions).

Maybe this errors from trial version restrictions?
Help me, myDAC is easy to use.

Unlikely the problem is in SP2. We could reproduce the problem with SP1.

Yes, it is so. Try to set at the dialog Project - Options - Packages

"Build with runtime packages"

and add to the list of runtime packages "dac50;mydac50"

With this settings all works ok, but this is not optimal idea.
When J buy, for example, MyDAC Standard package (no source), this problem remaining?

You are right, it is good only as a temporary solution.

The problem is caused only by particularities of trial version.
