Hi,

I call a standard DLL in my program.  The DLL uses ADO and my program 
uses ADO too.  I use data module to use ADO.  I am sure that the DLL 
calls CoInitialize.

When I try to run my program, I get the message "EOleSysError 
'CoInitialize is not called" and the program stops at the constructor of 
my data module.

Where should I put the CoInitialze?

Thanks

If your program uses ADO from a different thread other than the Main VCL
thread, then that thread must call CoInitialize prior to making any ADO
calls.
