Sending variables using shell from one .exe to another .exe . Easy for most people

Hello to all

I got the following code:

Dim MyVars as string
MyVars="Yes"
Shell "c:\winnt\ScrSaver.exe MyVars"

Now i am looking how to send the same variable (MyVars) where MyVars="NO" and WITHOUT the ScrSaver.exe been executed again!! Source Code would be usefull if you can.
Anyone any ideas????

Hi AW

Why do you suggest me to do it this:
Shell "c:\winnt\ScrSaver.exe " & MyVars

rather than this:
Shell "c:\winnt\ScrSaver.exe MyVars"

Whats the difference???

This will pass the value of MyVars to the exe:

Shell "c:\winnt\ScrSaver.exe " & MyVars

where this will pass the Text "MyVars" to the exe instead of the value:

Shell "c:\winnt\ScrSaver.exe MyVars"

The difference is between direct assignment and in-direct referencing.

1. Shell "c:\winnt\ScrSaver.exe MyVars" is direct assignment. The command processor sees "c:\winnt\ScrSaver.exe MyVars" directly from Shell.

2. Shell "c:\winnt\ScrSaver.exe " & MyVars is in-direct referencing. When MyVars = "Yes", the command processor sees "c:\winnt\ScrSaver.exe Yes" as referenced from Shell.
