Calling Utilities

I would like to know how i can call utility programs as anti-virus, scan disk, defragment, etc. from a vb program. Also how would i write the code in order for them to execute from my program without any user intervention.

Thanks to all that respond.

To execute another program :

VB Code:

Shell "SomeApp.exe",1

:)

In crptcblade's post, the Shell Statement can include any command line arguments or switches that the external program may use to automate operations. The would be included in the "SomeApp.exe" according to the specification of the external program.

For example:

VB Code:

Shell "SomeApp.exe Arg1; Arg2",1
