 Optional timeout As Integer)

[C#]

using Microsoft.CommerceServer.Interop.Targeting;
…
public void WaitOnOperation(objectvarOpID,
 inttimeout);

Parameters

[Visual Basic .NET]

  • varOpID
    An Object that specifies the ID of the operation on which to wait. For more information about where to obtain Operation IDs, see the Remarks section.
  • timeout
    An optional Integer that specifies a timeout. This method returns either when the specified operation completes or when the number of seconds specified by the timeout parameter has elapsed, whichever happens first. A value of zero (the default) specifies an infinite time to wait for the operation to complete.

Remarks

This method cannot be called from a scripting language such as VBScript or JScript on an ASP page. ASP pages must use alternative techniques when dealing with asynchronous operations and should never wait on them explicitly.

The Operation ID passed to this method in the varOpID parameter can be obtained from any of the following calls when they are executed asynchronously:

In addition, the Operation IDs of all known operations can be retrieved using the GetOperations method.
