CantStartSingleInstanceException Class

Note: This class is new in the .NET Framework version 2.0.

This exception is thrown when a subsequent instance of a single-instance application is unable to connect to the first application instance.

Namespace: Microsoft.VisualBasic.ApplicationServices
Assembly: Microsoft.VisualBasic (in microsoft.visualbasic.dll)

[SerializableAttribute] 
public class CantStartSingleInstanceException : Exception
/** @attribute SerializableAttribute() */ 
public class CantStartSingleInstanceException extends Exception
SerializableAttribute 
public class CantStartSingleInstanceException extends Exception

A single-instance application differs from a normal application in that only one instance of the application can be running at a time. When a subsequent application instance starts, it attempts to contact the first instance application to pass its command-line arguments. If the first instance cannot be contacted, the CantStartSingleInstanceException is raised in the subsequent application instance. The Visual Basic Application Model does not provide any context information in the exception.

For more information, see Overview of the Visual Basic Application Model.
