I have a very small footprint, high priority task that I want to be able to determine whether or not 2 other tasks “exist”. How can I do this? Thank you for your help.

Store the handles of the two tasks in two variables when they are created, then set the value of the variables to null when the tasks are deleted. The high priority task can then check the value of the handle. If the handle is not null then the task exists.

Guys, Great, i will try those solutions singly or possibly both. Regards,
