I write an application that calls COM objects from PHP and I've used a small package Denwer for its debugging. Now came its deployment and it was installed a standard PHP package that integrates with IIS to run on a server. The standard PHP function executes successfuly but COM objects calling failes. Appers "'com_exception' with message 'Parameter 1: Type mismatch" in string
$objU = new COM ("Deans_Project.User");
Tell me please how to make working COM objects calls.
