(Resolved) - Class within a Class

[jcfowl]

We have created class modules and collections for
a project.

One Class is Called Project, it has several properties:
Customer, CustomerPhone#......

Each Project can have a Quality Assurance(class) which also
has it's own properties: Statement_of_Work, Batch_process....

The problem is that I want to access the Quality Assurance
Class from my Project Class Like So:

Dim MyProj as New Project
MyProj.QualityAssurance.Statement_of_work = "something"
---------this give me an error of Object not Set ------------


I can create New Projects and New Quality Assurances but
I cannot access them the way I stated above.

I am guessing that I have to link them somehow but I'm
not sure what to do.

Basically I just want to have a class within a class.
Any help is appreciated!!!

The parent class needs interfaces to the child class properties.

[jcfowl]

Could you be more specific. Do I need to place some
code inside the Initialize() statement of the Parent?
How do I set up the interfaces to the Child?

[GlenW]

However the child class initialises or sets a property the parent class needs to access this.
So if you want to set values of a child class on the initialisation of the parent class call the child classes properties from the parent class initialise method.

Heres a bad example.
If you have a class BOX and a class BIGBOX
BIGBOX contains 2 BOXs
A BOX has 1 variable mySize
So BOX has a property SIZE thats set its mySize.
If you initialise a BIGBOX you need to call the SIZE property of each of its BOXs to set them.
So the outside interface to each BOX is through a BIGBOX.

I can't believe I wrote that double dutch crap.
Can somebody else explain better please?

In class cProject:

Public Property Get QualityAssurance() As cQualityAssurance

Dim qaThis As New cQualityAssurance
'set qathis properties for this project..projectid?
Set QualityAssurance = qaThis

End property

Hope this helps,
