OnLaunchAppAndWaitCallback

InstallShield 2016 » InstallScript Language Reference

Project • This information applies to the following project types:

The OnLaunchAppAndWaitCallback event handler is called while the installation is waiting for an application to launch if LAAW_OPTION_USE_CALLBACK was specified when calling the LaunchApplication function. The event is called in the intervals determined by the amount of time specified in the LAAW_PARAMETERS.nCallbackInterval parameter.

If the installation contains multiple LaunchApplication calls in which LAAW_OPTION_USE_CALLBACK was specified, the same event is called during each wait. In this case, use the LAAW_PARAMETERS.szCommandLineResult parameter to determine which call is currently being executed. You can return LAAW_CALLBACK_RETURN_CONTINUE_TO_WAIT to continue waiting or LAAW_CALLBACK_RETURN_END_WAIT to end the wait immediately.

function number OnLaunchAppAndWaitCallback( )

begin

    return LAAW_CALLBACK_RETURN_CONTINUE_TO_WAIT;

end;

Note • This event handler appears in installations and object projects. Any specified override for this event applies on to the script in which it is overwritten. An override in the main installation script does not affect contained objects and an override in an object project has no effect on the main installation script.
