Hi,

I'm trying to share a DataModule with ADO components between an Exe and a
Dll.

So after, I call from the Exe LoadLibrary and GetProcAdresse, I invoke the
export procedure passing in parameter a pointer of my DataModule.
In the Dll, oftenly I can use TADOComponent one time (close and open on
TADOQuery), the second time I've got an access violation.

typedef void (WINAPI *PPROCEDURE) (TDataModule *);
module = LoadLibrary("myDll.dll");
if (module != 0)
{
    procedure = (PPROCEDURE) GetProcAddress(module, "exportprocedure");
    if (procedure != NULL)
   {
        procedure(MyDataModule);
   }
}

Any idea what to do?

Thanks
