Fault Injecton

[fergmj]

I need to write some software that allows me to inject faults into other pieces of software that I am testing.

There are a couple of things I am trying to understand.

1. How do I get my app (which will be written in Borland C++ Builder 5.0) to open another application?

2. I want to use checkboxes so that when a user checks a "Network Disconnect" box, the application simulates not having a network connection or having lost the connection. I know how to do the checkboxes and all but I don't how to simulate the loss of a network.

Can anyone help me on these two items?

Thanks

The first is fairly easy, see the FAQ in this forum for CreateProcess. James P. Cottingham

Thanks. That helps a lot. Now I just need to figure out how to make my app inject faults.

I can think of one way, have your apps accept switches like many command line programs do. For example, "MyApp /NoNetwork" would start the app without a network connection. Other possiblilities include using DDE or COM to communicate to your apps. Just a thought.
