Starts running a background operation and includes a parameter for use by the background operation.
Namespace: System.ComponentModel
Assembly: System (in System.dll)
Syntax
Public Sub RunWorkerAsync ( _
argument As Object _
)
public void RunWorkerAsync(
Object argument
)
Parameters
- argument
Type: System..::.Object
A parameter for use by the background operation in the DoWork event handler.
Exceptions
| Exception | Condition |

Remarks
The RunWorkerAsync method submits a request to start the operation running asynchronously. When the request is processed, the DoWork event is raised, which in turn starts running your background operation.
If your background operation requires a parameter, you can provide it as the argument parameter to RunWorkerAsync.
If the background operation is already running, calling RunWorkerAsync again will raise an InvalidOperationException.
