Parameters

  • varSrc
    [in] The CComVariant or VARIANT to be assigned to the CComVariant object. The contents of the source variant are copied to the destination without conversion.

  • bstrSrc
    [in] The BSTR to be assigned to the CComVariant object. The type of the CComVariant object will be VT_BSTR.

  • lpszSrc
    [in] The character string to be assigned to the CComVariant object. You can pass a zero-terminated wide (Unicode) character string to the LPCOLESTR version of the operator or an ANSI string to the LPCSTR version. In either case, the string is converted to a Unicode BSTR allocated using SysAllocString. The type of the CComVariant object will be VT_BSTR.

  • bSrc
    [in] The bool to be assigned to the CComVariant object. The bool argument is converted to a VARIANT_BOOL before being stored. The type of the CComVariant object will be VT_BOOL.

  • nSrc
    [in] The int, BYTE, short, long, LONGLONG, ULONGLONG, unsigned short, unsigned long, or unsigned int to be assigned to the CComVariant object. The type of the CComVariant object will be VT_I4, VT_UI1, VT_I2, VT_I4, VT_I8, VT_UI8, VT_UI2, VT_UI4, or VT_UI4, respectively.

  • fltSrc
    [in] The float to be assigned to the CComVariant object. The type of the CComVariant object will be VT_R4.

  • dblSrc
    [in] The double to be assigned to the CComVariant object. The type of the CComVariant object will be VT_R8.

  • cySrc
    [in] The CY to be assigned to the CComVariant object. The type of the CComVariant object will be VT_CY.

  • pSrc
    [in] The IDispatch or IUnknown pointer to be assigned to the CComVariant object. AddRef will be called on the interface pointer. The type of the CComVariant object will be VT_DISPATCH or VT_UNKNOWN, respectively.

    Or, a SAFEARRAY pointer to be assigned to the CComVariant object. A copy of the SAFEARRAY is stored in the CComVariant object. The type of the CComVariant object will be a combination of the original type of the SAFEARRAY and VT_ARRAY.

  • cSrc
    [in] The char to be assigned to the CComVariant object. The type of the CComVariant object will be VT_I1.
