Ignoring Custom action return code

[Phil]

This article:
http://msdn.microsoft.com/en-us/library/aa368072%28VS.85%29.aspx
states that: "custom actions that are executable files must return a value
of 0 for success".
The program I need to call returns a value of 1 :-(
However it also goes on to say:
"To ignore return values, set the msidbCustomActionTypeContinue bit flag in
the Type field of the CustomAction table."
How do I set this flag in my VS2008 setup project?

Thanks,
Phil.
