Can Access reconize all of the current windows open.  Say I have a xls, and doc files open and minimized.  Is there a way Access can reconize when I open say a powerpoint file and then perform some functions after it is opened?

(Q) How do I find out is Excel or Word is running in the background?

(A) You can use the fIsAppRunning function to check if an application is running. Pass the Appplication name to this function. An optional argument is passed as True or False if you want to activate the Application. For example, if you want to activate Word if it's found running, try this in the debug window:


If you just want to know if Word is running or not, you can simply call the function like this:


Note: New class names can be added to the Select case structure to extend functionality.
