Friend modifier and derived forms

[Chris Leffer]

Hi.

The documentation says that variables declared Friend can be used
anywhere on the same program. I have a VB form that is the base form for
other forms on the same application. Controls that have the Modifiers
property set to Friend on the base form can not be modified on the
derived forms. Why?
Shouldn't Friend controls be acessed anywhere on the same program?

Regards,
Chirs Leffer

Hi Chris,

The same is true with C#' internal keyword.
Don't know why, though - it should work without problems.
The funny thing is, that if you add protected infront of internal/friend it
works - it is more restricted then without protected.

Not true - Internal means "Anywhere in the current assembly", and protected
means "in this class or any derived class". Using both internal and
protected on the same variable applies the complete range of both scopes to
the variable, so you can access it from anywhere you could with either
internal or protected.

Hi Jason,

Ooops, yes, my mistake - typed too fast
But still it is not a valid reason for forms inheritance designer.
