There are four ways to call APIs on the COM object: Generating a C++ namespace Call-by-name Through a script engine Using the native COM interfaces Generating a C++ Namespace To generate this contact form
Accessing the Object API ActiveQt provides a Qt API to the COM object, and replaces COM datatypes with Qt equivalents. The VARIANT buffer is filled with a SAFEARRAY by @[id(10), helpstring("method CreateCompatibleBuffer")] HRESULT CreateCompatibleBuffer(VARIANT* buffer);@ ,as the documentation states, before I fill it with GetQuants(). in class "DoSpotPC", this member function prototype: inline int doGetDeviceNumber(int Hardware, int& numDev); is not correct, according to the manual, this member function prototype should be short doGetDeviceNumber(short Hardware, short* numDev); The ActiveX Test Container demonstrates loading of script files.

If the parameter type would be wrong, then the control would complain about a type mismatch, and not throw an exception. It works for strings, but not for variants that are supposed to be filled by the control. To make sure I have the right types, I tried something like this: @ai->dynamicCall("GetQuants(const int&, const int&, const QVariant&, const int&)",0,count,analog_buffer,0);@ Here I get the error: "Error calling IDispatch member GetQuants: The control might require administrator rights, or a license key.
