I am trying to use to timer to determine when it is time to start another process. I have observed the my ongoing processes are not independent of the processes I started when it was time to do so. Specificly when the process started by the timer selected a different data file and my ongoing process then has the newly selected data file as its data file. Any way to pause the ongoing process until the time triggered process is complete, or alternatively keep the two process seperate ?

Is it possible to pause other processes when the timer fires ?

Yes, but only indirectly.
Assuming that the running processes have some kind of loop structure, all you have to do is get that process to check some visible (to the process, not the user) property and if it is set (or unset) get the loop to pause. Then when you start your new process remember to set that property as it initiates enter and unset it as it closes.

for me it is eaiser to control when the timer process fires. Im my main process i will set the timer.interval to 0 [zero] while my process compleates. then when my main preocess is done it will set the timer to its proper interval time

regarding data/alias access, you can keep two processes seperate by using seperate datasessions.
A timer event should always be programmed to reset for example the current work area, so it does not cause side effects. But a timer does not run parallel to the main process, it interrupts the process and after finishing gives back control.
if you start a differnt process via a timer, and want that new process to have it's own environment, you have several possibilites. Some that come to my mind are, starting a new process by starting a new instance of an EXE, creating a form with private datasession, creating some processing class based on the session class (non visual).
