Definition
HRESULT IMSCSPage_3_0::RequestTime(BSTRbstrName,VARIANTvtDefault,VARIANTvtMin,VARIANTvtMax,VARIANTvtLocal,VARIANT*pvtRet);
Parameters
bstrName
[in] A BSTR that contains the name of the URL-query string or form-post variable to retrieve.
vtDefault
[in, optional] A VARIANT that contains the string to return if the specified URL-query string or form-post variable does not exist or contains no value. If this parameter is not supplied, the method returns NULL. The default cannot contain DateTime or Date values.
vtMin
[in, optional] A VARIANT that contains the time value that specifies the low end of the range against which to validate the bstrName parameter. If the VARIANT is of type vtMissing, the vtMin parameter value is not considered in the validation process.If the converted value is less than vtMin, the method returns NULL.
vtMax
[in, optional] A VARIANT that contains the time value that specifies the high end of the range against which to validate the bstrName parameter. If the variant is of type vtMissing, the vtMax parameter value is not considered in the validation process. If the converted value is greater than vtMax, the method returns NULL.
vtLocale
[in, optional] A VARIANT that contains the number that specifies the locale to use to convert the DateTime value. If this value is not specified, the RequestTime method uses the value of the Locale property of the DataFunctions object.
pvtRet
[out, retval] A pointer to a VARIANT used to return the date. If any validation fails, the value will be set to NULL.
