Hi,

I use C++ Builder 5 Enterprise. I want to create a TADOConnection in a
console application. My sample code is listed below:

#include <vcl.h>
#pragma hdrstop
#include "ADOdb.hpp"
#include <iostream.h>
#include <conio.h>
#pragma argsused
int main(int argc, char* argv[])
{
 try
 {
  TADOConnection* ADOConnection(new TADOConnection(NULL));
  delete ADOConnection;
 }
 catch (Exception& E)
 {
  cerr << E.Message.c_str();
  getch();
 }

 return 0;
}

The above code gives an error message saying: "CoInitialize has not been
called". I suspect that the problem lies with the NULL that I pass to the
constructor. The help file says that I should pass a window handle when
creating the TADOConnection in a non-VCL window. I am not new to C++ Builder
but I can't seem to be able to write the code to do what the help says. Can
someone please give me an example of what I need to do?

Thanks
Louis
