CDispParams Class

CDispParams Class Hierarchy

The CDispParams class implements the DISPPARAMS structure used in Automation as a C++ base class. The IDispatch::Invoke method uses the OLE DISPPARAMS structure to contain the arguments passed to any method or property.

The DISPPARAMS structure is defined as follows:

typedef struct FARSTRUCT tagDISPPARAMS{
VARIANTARG FAR* rgvarg;               // Array of arguments
   DISPID FAR* rgdispidNamedArgs;     // Dispatch IDs of named arguments
   unsigned int cArgs;                // Number of arguments
   unsigned int cNamedArgs;           // Number of named arguments
} DISPPARAMS;
