  • Article

Retrieves detailed information about a single COM+ component hosted in a process.

Syntax

HRESULT GetComponentDetails(
  [in]  REFGUID                  ApplicationInstanceId,
  [in]  DWORD                    ProcessId,
  [in]  REFCLSID                 Clsid,
  [in]  DWORD                    Flags,
  [out] ComponentSummary         *Summary,
  [out] ComponentStatistics      *Statistics,
  [out] ComponentHangMonitorInfo *HangMonitorInfo
);

Parameters

[in] ApplicationInstanceId

The application instance GUID that uniquely identifies the tracked process to select, or GUID_NULL if the ProcessId parameter will be used for selection instead.

[in] ProcessId

The process ID that identifies the process to select, or 0 if ApplicationInstanceId will be used for selection instead.

[in] Clsid

The CLSID of the component.

[in] Flags

A combination of flags from the GetAppTrackerDataFlags enumeration to select which data is returned. The following flags are supported: GATD_INCLUDE_CLASS_NAME (if retrieving a summary), GATD_INCLUDE_APPLICATION_NAME (if retrieving a summary).

[out] Summary

On return, a ComponentSummary structure with summary information for the component. This parameter can be NULL.

[out] Statistics

On return, a ComponentStatistics structure with statistics for the component. This parameter can be NULL.

[out] HangMonitorInfo

On return, a ComponentHangMonitorInfo structure with hang monitoring configuration for the component. This parameter can be NULL.

Return value

This method can return the standard return values E_INVALIDARG and E_OUTOFMEMORY, as well as the following values.

Return code Description
S_OK
 The method completed successfully.
COMADMIN_E_APP_NOT_RUNNING
 The specified process does not exist, or is not hosting any tracked COM+ applications.
COMADMIN_E_OBJECT_DOES_NOT_EXIST
 The specified component does not exist in the specified process.

Remarks

A process may be selected by its application instance ID or its process ID, but not both. Selection by application instance ID is generally preferred, because process IDs may be reused after a process terminates. However, selection by process ID may be useful if you obtain the process ID from some other source, such as a command line argument to your program.

You may request any or all of the information available for the component by passing non-NULL values for Summary, Statistics, or HangMonitorInfo. At least one of these parameters must be non-NULL.
