Why?

struct DISPPARAMS {
    VARIANTARG* rgvarg; // the actual arguments
    DISPID* rgdispidNamedArgs; // ids for named parameters [NULL]
    unsigned int cArgs; // number of parameters
    unsigned int cNamedArgs; // number of named parameters [0]
};

BSTR bstrMyArg = L"some text";

VARIANT var;
::VariantInit(&var);
var.vt = VT_BSTR; // the type variant will consider
var.bstrVal = bstrMyArg; // the value it is holding

DISPPARAMS dispparameters;
dispparameters.cArgs = 1; // a single argument
dispparameters.rgvarg = &var; // what's the argument
// these two are not used [by us]
dispparameters.cNamedArgs = 0; 
dispparameters.rgdispidNamedArgs = NULL;
