Hi Everybody!

I'm relatively new in programming and have a problem.

I created a VCL Forms Application (BDS 2006) and use a ADOConnection to
connect with an MySQL Database. Everything works fine on my machine
(where I created the app, but on every other PC (I tested 5 Win XP and
1 Win2k) I get an exception as soon as I try to open the DataSet. The
curious thing about it is, that I use 4 Datasets and the exception is
only by two of them! I don't have any BeforeActivate... Events
programmed.

This is the Code:
ConnectionAB->DataSet1->Open(); (Exception is caused)
ConnectionAB->DataSet2->Open(); (Exception is caused)
ConnectionAB->DataSet3->Open(); (NO Exception is caused)
ConnectionAB->DataSet4->Open(); (NO Exception is caused)

The Error Message is: "Das Objekt war geöffnet" (Which means "The
Object was already opened"
I already found out that this message is an "EOleException Type"

Can anybody help me?

Thanks!
Chris
