When must I set a variable to “Nothing” in VB6?

Question

In one of my VB6 forms, I create several other Form objects and store them in member variables.

Private m_frm1 as MyForm
Private m_frm2 as MyForm

// Later...
Se         


        

Answer 1

Strictly speaking never, but it gives the garbage collector a strong hint to clean things up.

As a rule: do it every time you're done with an object that you've created.
