I use <code>UniDac</code> component to connect to <code>PostgreSQL</code>. My <code>Query</code> is running in a separate thread. Now when I use <code>CoInitialize</code> in the thread, I receive this compiler error: <blockquote> - [DCC Error] QryThread.pas(41): E2003 Undeclared identifier: 'CoInitialize' </blockquote> Why?

Because <code>ActiveX</code> is missing in the uses list.

Why is CoInitialize an undeclared identifier?

Because ActiveX is missing in the uses list.
