VBScripting Solutions: Emulating Windows Synchronization Objects

To read and write variables from the current user's environment, you must specify the keyword User when calling the Environment property. You set a variable just as you would with a regular collection. For example,

Set UserEnv = _
   shell.Environment("User")
UserEnv("VarName") = value

or

shell.Environment("User") _
   ("VarName") = value

Modifying the Child Programs
Now that you've set the variable, consider the simple but effective script that Listing 1 shows. At the end of this code, you must add a couple of lines to create an application-specific variable with a conventional value. In this example, I've created an environment variable called App3_Finished, which callout A in Listing 1 shows, that I set to a value of True. If you don't have access to the source code (i.e., signed code) or if you don't want to modify the source code, simply create a new .vbs file that spawns the original code and add the extra code at the end of it, as Listing 2 shows. . . .
