CoInitialize has not been called

Whenever I try to do any database work inside of a thread I get this error "CoInitialize has not been called"

It doesn't matter what I do, Insert, Delete, Select

But the same code works fine if it's used in a form any ideas?

I've tried:

initialization
  CoInitializeEx(nil,COINIT_MULTITHREADED);
finalization
  CoUninitialize;

and I've tried

and initialization
  CoInitialize(nil);
finalization
  CoUninitialize;

I've also tried putting this code in a unit by itself and making it the first statment in my Uses Clause

unit ComInit;

interface

uses
  ActiveX;

implementation

initialization
  CoInitializeEx(nil,COINIT_MULTITHREADED);
finalization
  CoUninitialize;
end.


All to no avail. Although I do get a different error message when I try it the last way.

Any ideas

The other error I get is Could not obtain OLE control window handle.

Hmmmm... Am no expert here, but why don't you call CoInitialize from within the thread?
LummieCommented:
If you call coInitialize in the intiailzation and finalization sections then this gets run when the unit is loaded, not in the instance of the thread.

Move the coinitialize and uninitialize to a try finally block in your TThread.execute or in the constructor / destrcutor of your thread class.
