Parameters

listName[C++]
[in] A BSTR that provides the name for the new list.
listName[Visual Basic]
A String that provides the name for the new list.
listDesc[C++]
[in] A BSTR that provides a description for the new list.
listDesc[Visual Basic]
A String that provides a description for the new list.
lFlags[C++]
[in] A long that specifies the bitmask flags that control the type of list created.
lFlags[Visual Basic]
A Long that specifies the bitmask flags that control the type of list created.
userFlags[C++]
[in] A long that contains application specific user flags. Not used by the ListManager object.
userFlags[Visual Basic]
A Long that contains application specific user flags. Not used by the ListManager object.
DWConnStr[C++]
[in] A BSTR that contains the connection string for the Data Warehouse.
DWConnStr[Visual Basic]
A String that contains the connection string for the Data Warehouse.
OLAPConnStr[C++]
[in] A BSTR that contains the OLAP connection string.
OLAPConnStr[Visual Basic]
A String that contains the OLAP connection string.
ReportStatusId [C++]
[in] A BSTR that contains the ReportStatusID of the report to be imported.
ReportStatusId [Visual Basic]
A String that contains the ReportStatusID of the report to be imported.
bAsync[C++]
[in] A BOOL that specifies whether the creation operation is performed synchronously or asynchronously. A value of True indicates asynchronous processing.
bAsync[Visual Basic]
A Boolean that specifies whether the creation operation is performed synchronously or asynchronously. A value of True indicates asynchronous processing.
pvarOpID[C++]
[out, optional] A pointer to a VARIANT used to return an Operation ID.
pvarOpID[Visual Basic]
An optional Variant used to return an Operation ID.
pvarID[C++]
[out, retval] A pointer to a VARIANT used to return the ID of the new list.

Return Values

[C++] This method returns an HRESULT indicating whether it completed successfully. See the Error Values section for more details.

[Visual Basic] If this method completes successfully, it returns a Variant that contains the ID of the new list.

Error Values

[C++] This method returns S_OK (0x00000000) to indicate success and either standard or custom COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

[Visual Basic] This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to either standard or custom COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

The following table shows the custom COM errors that this method can return.

Constant	Value	Description
E_LM_CONNECTIONFAILED	[C++] 0x8C400001 [Visual Basic] &H8C400001	Failed to establish database connection.
E_LM_CREATE_OBJECT	[C++] 0x8C400017 [Visual Basic] &H8C400017	Unable to create the object.
E_LM_INVALID_FLAGS	[C++] 0x8C400005 [Visual Basic] &H8C400005	Invalid flags value.
E_LM_LIST_ALREADY_EXISTS	[C++] 0x8C400007 [Visual Basic] &H8C400007	The specified list has already been created.
E_LM_MAILABLE_LIST_NO_EMAILS	[C++] 0x8C40000D [Visual Basic] &H8C40000D	The list is designated as a Mailable list but does not contain an rcp_email column.
E_LM_OPER_CANCELED	[C++] 0x8C40000B [Visual Basic] &H8C40000B	The operation was canceled.
E_LM_REPORTRENDERERFAILED	[C++] 0x8C40001A [Visual Basic] &H8C40001A	The report rendering object failed during Analysis report export to ListManager. See the Application event log message logged by that object describing the problem.
E_LM_SQLERROR	[C++] 0x8C400003 [Visual Basic] &H8C400003	Error while executing SQL/ADO operation.
E_LM_USER_LIST_NO_GUIDS	[C++] 0x8C40000E [Visual Basic] &H8C40000E	The list is designated as a User list but does not contain an rcp_guid column.
OLE_E_BLANK	[C++] 0x80040007 [Visual Basic] &H80040007	The ListManager object has not been properly initialized.

[C++] Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

[Visual Basic] Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.

Remarks

This method calls into the ReportRender object, passing it the DWConnStr, OLAPConnStr, and the ReportStatusId parameters along with a connection string to the database used by the ListManager object, and the table name that it should create.

For a list of possible values for the lflags parameter, see the GetListFlags method.
