ListManager.Subtract Method (PIA)
Use this method to subtract one mailing list from another mailing list, and to place the result in a third list.
Definition
[Visual Basic .NET]
Imports Microsoft.CommerceServer.Interop.Targeting
…
Public Sub Subtract(srcList As Object,
lessList As Object,
resList As Object,
errLimit As Integer,
bAsync As Integer,
Optional ByRef pvarOpID As Object)
[C#]
using Microsoft.CommerceServer.Interop.Targeting;
…
public void Subtract(objectsrcList,
objectlessList,
objectresList,
interrLimit,
intbAsync,
ref objectpvarOpID);
Parameters
[Visual Basic .NET]
- srcList
An Object that contains the ID or name of the list from which elements will be subtracted. - lessList
An Object that contains the ID or name of the less list. - resList
An Object that contains the ID or name of the list into which the results of the subtraction operation will be placed. - errLimit
An Integer that is not used. - bAsync
An Integer that specifies whether the copy operation is performed synchronously or asynchronously. A value of 1 indicates asynchronous processing. A value of 0 indicates synchronous processing. - pvarOpID
An optional Object used to return an Operation ID. This Operation ID is used in subsequent processing concerning this operation.

An int that is not used. - bAsync
An int that specifies whether the copy operation is performed synchronously or asynchronously. A value of 1 indicates asynchronous processing. A value of 0 indicates synchronous processing. - pvarOpID

Exceptions
This method may throw one of many mapped exceptions or an exception of type COMException. See Standard COM Errors for additional details.
[Visual Basic .NET]
The following table shows the custom COM errors that a COMException can wrap.
Value | Description |
---|---|
&H8C400008 | The specified list is currently busy with another operation. |
&H8C40001D | The specified list is in a FAILED state and may not be used for the operation. |
&H8C400006 | The specified list does not exist. |
&H8C400011 | The operation requires a Mailable list and the specified list is not a Mailable list. |
&H8C40000B | The operation was canceled. |
&H8C400003 | Error while executing SQL/ADO operation. |
&H80040007 | The ListManager object has not been properly initialized. |
[C#]
The following table shows the custom COM errors that a COMException can wrap.
Value | Description |
---|---|
0x8C400008 | The specified list is currently busy with another operation. |
0x8C40001D | The specified list is in a FAILED state and may not be used for the operation. |
0x8C400006 | The specified list does not exist. |
0x8C400011 | The operation requires a Mailable list and the specified list is not a Mailable list. |
0x8C40000B | The operation was canceled. |
0x8C400003 | Error while executing SQL/ADO operation. |
0x80040007 | The ListManager object has not been properly initialized. |
Remarks
The result list must exist prior to calling the method; however, any data in the list will be overwritten.
This method keys on the rcp_email column, and therefore both the source (srcList parameter) and less (lessList parameter) lists must be Mailable lists (LISTFLAG_MAILABLE set to True). Records from the source list that do not have duplicate e-mail addresses (rcp_email)**in the less list are copied to the result (resList parameter) list. Any existing data in the result list is deleted.
The parameter pvarOpID contains valid data only if the subtraction operation is performed asynchronously.
