How to change a filename in memory?

[giv]

In the Documentation of VH2011 on this link in described at chapter 4 paragraph 4 a hook method described as:

4. Form

Normally, the form file included in the EXE file is read-only, it can not be
changed.

Use OllyDbg or WinHex to scan memory, then change the form file name in memory. For example, we can change the form file name in memory (file name description) from VHTEST.SC* to XXTEST.SC*, and create a new form file VHTEST.SCX.

Reference code:
PROCEDURE Init
vh()
ENDPROC

In terms of OllyDBG and Winhex i'm a novice.
Please, someone could enlight me how to do such a opperation as change the name of a file in memory of a running program in such way that running program to call the dummy filename instead of the correct filename.
A tutorial will pe highly apreciated.
Thanks!
