A Task object represents a currently running Windows application (not just Microsoft Word). Task objects are kept in the Tasks collection.
One of the more useful properties of a Task object is the Name property. For instance, the following code prints (to the Immediate window) the names of all of the currently running tasks:
Dim t as Task For Each t in Tasks Debug.Print t.Name Next t
You might find it amusing to run this code on your system. You will probably see some rather bizarre looking tasks.
On a more useful note, the Tasks collection has a method called Exists that indicates whether a certain task is running. For instance, the following code determines whether Microsoft Excel is running. If so, the code activates Excel and maximizes it; if not, the code starts Excel using the VBA Shell function, whose purpose is to run an executable program (the path is correct for my PC):
If Tasks.Exists("Microsoft Excel") = True Then Tasks("Microsoft Excel").Activate Tasks("Microsoft Excel").WindowState = wdWindowStateMaximize Else Shell "I:\Office97\Excel\Excel.exe", vbMaximizedFocus End If
