Pointer to Form

I have observed one interesting fact:

I have typical App with Frame and Form on it ( MyFrame Class inherited from Frame, MyForm Class inherited from Form)

Inside MyFrame Class I am able to get pointer to MyForm this way:
pForm1 =static_cast<Form*>(GetControl(L"IDF_FORM"));
but inside MyForm class I am unable to do this (returned adress is 0)

Could anybode explain me what the difference? Why it was allowed in one case but denied in another?

p.s. I have found how to get pointer to Form : just use 'this' enough, or
use ...GetAppFrame()->GetFrame()->GetCurrentForm();

Thank you in advance.
Alexey.

Have you tried the following ? Form* pForm = static_cast< Form* >(GetParent());

Containers maintain a list for child controls and GetControl() basically searches for the control in this list and returns the appropriate one. So inside form methods GetControl() won't be able to able to find the frame pointer as Frame is not child of Form.

Ok. Thank you for explanation! p.s. static_cast< Form* >(GetParent()); returns pointer to Frame. Alexey.
