Problem with Indy, ADO and Delphi 2009

I've a problem using ADO and indy in Delphi 2009.

My project always crashes on exit when running in delphi 2009.

This can be reproduced by doing the following in delphi 2009:

  1. Create a new project
  2. Add TAdoConnection component to the form. Create a connection to a sql server database and set the connected property to true.
  3. Add IdHttp to the uses clause of the form.
  4. Run, on closing the application the error occurs every time.

This is the error details

As soon as I remove IdHttp from the uses clause, no error occurs.

Anyone got any ideas as to what i can do to sort this out, or suggest a different component suite to Indy I can use for http.

Indy is completely separate from ADO. There is no way the mere presence of the IdHTTP unit in the uses clause (especially if you are not actually using the TIdHTTP component) can cause such a crash. Something else has to be happening, and removing the IdHTTP unit is just a coincidence. You are going to have to step through the app's shutdown code to see what is really happening.

This is probably old news now but I had exactly the same issue but had neglected to install Update Pack 4 after a reinstallation. Do so cured the problem.
