IAppManager.LaunchDoc()

+

Description:

+

The LaunchDoc method launches an application based +on a given document. This method automatically determines which application +to launch for the specified document.

+

The application can be launched as chained (embedded) or stand-alone. +For more information about embedded and stand-alone applications, see section Accessing and launching installed applications.

+

This method can be called both synchronously and asynchronously.

+

Syntax:

+

For synchronous calls:

+
result = so.IAppManager.LaunchDoc(criteria);
+ +

For asynchronous calls:

+
result = so.IAppManager.LaunchDoc(criteria, callback);
+ +

Arguments:

+
    +
  • criteria:

    + +

    This is an object that specifies which application to launch. For more +information about the object properties and how to define them, see section Criteria for launching an application.

    + +
  • +
  • callback:

    + +

    The callback argument is the name of the method +that is executed when an asynchronous LaunchDoc call +has status information to return. You must define this method separately. +Follow the instructions in section Defining the callback handler for an asynchronous method to +define the callback method.

    +

    This argument is used only with an asynchronous LaunchDoc call.

    + +
  • +
+

Return value:

+

+

If synchronous, the LaunchDoc method returns an +object that contains the name of the newly created document, if applicable, +an error code, and an error message.

Property

+
+

Description

+
+

Value

+
+

[result.ReturnValue]

+
+

This is a string that contains the name of the newly created document, +if any.

+

This property is optional. A new document is created only when both +of the following are true:

+
    +
  • criteria.MIMEType is specified as input.

  • +
  • The launched application creates a new document.

    +
  • +
+

A document name is never returned when criteria.Document is specified as input.

+
 
+

result.ErrorCode

+
+

This is a number that specifies a predefined error code.

+
+

See Service API error codes.

+
+

result.ErrorMessage

+
+

This is a text string that describes the error.

+
+

See AppManager Service API error messages.

+
+

If asynchronous, the LaunchDoc method returns an +object that contains the initial return value for the asynchronous call it +started (see the following table). The actual result information is returned +by the callback method +in the ReturnValue property of its result object. The +returned information is described in the preceding table.

+

Note: If Cancel is +called on an ongoing asynchronous request, LaunchDoc does +not return a notification when the launched application terminates.

This is a number used as an identification to match transactions started +with the asynchronous LaunchDoc call to one or more calls +it generates to callback.

+
+

This is a number that specifies a predefined error code.
