Public Function RetrieveByPrincipal(
ByVal Caller As CUserAuth,
ByVal Principal As CSecurityPrincipal,
ByVal StartDate As String,
ByVal EndDate As String,
ByVal ActivityTypeCode As ObjectType(),
ByVal ActivityStateCode As ACTIVITY_STATE(),
ByVal ColumnSetXml As String
) As String
[C#]
public string RetrieveByPrincipal(
CUserAuth Caller,
CSecurityPrincipal Principal,
string StartDate,
string EndDate,
ObjectType[] ActivityTypeCode,
ACTIVITY_STATE[] ActivityStateCode,
string ColumnSetXml
);
[C++]
public: String* RetrieveByPrincipal(
CUserAuth* Caller,
CSecurityPrincipal* Principal,
String* StartDate,
String* EndDate,
ObjectType ActivityTypeCode __gc[],
ACTIVITY_STATE ActivityStateCode __gc[],
String* ColumnSetXml
);
Parameters
Caller
Specifies the identity of the caller. The caller must have the prvReadActivity privilege to perform this action. See CUserAuth.
Principal
Specifies the principal whose activities you want to retrieve. See CSecurityPrincipal.
StartDate
Specifies the start date. Use this to retrieve activities that happen after this date.
EndDate
Specifies the end date. Use this to retrieve activities that happen before this date.
ActivityTypeCode
Retrieves the types of activities specified in this array. See ObjectType.
ActivityStateCode
Retrieves activities in the states specified in this array. See ACTIVITY_STATE.
ColumnSetXml
Specifies an XML string describing the set of columns that is to be retrieved. Passing "" or null returns all columns. You can find the valid column names in activity.xsd. See also ColumnSetXML Schema.
Return Value
Returns a String type that specifies the XML data containing the requested activities. The fields that are returned depend on what fields are specified in the ColumnSetXml parameter. The XML schema is described by activity.xsd.
Remarks
If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.
All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}
