Delphi - Is TClientDataset Thread Safe?

Question

I have a TClientDataset that is managed in Thread 1.

In a different thread I have a cloned Image of the TClientDataset.

Will I run into threading problems?

Answer 1

In a word: No.

All of the VCL should be considered "thread unsafe". Any calls to visual components in a TThread should be made in a Synchronize event.

Any VCL/RTL class should be created and destroyed entirely within a TThread.
