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 Back to top Erol Fornoles Guest Posted: Sat Nov 18, 2006 10:18 pm    Post subject: Re: EOleException when opening Dataset What does those 4 datasets contain?
