How can I convert from CString to PSTR?
I mean, I have an identifier m_Name which is a CString object. Actually, m_Name ist just a text input.
I want to pass it as a parameter to a method requiring PSTR parameters. What can I do??

Pointer to a null-terminated Windows character string
CString object consists of a variable-length sequence of characters.

Doesn't work (directly)!!

My code is:

PSTR text=m_Name;
(m_Name is a CString member variable)

When trying to compile, I always get this error:

error C440: 'initializing' : cannot convert from 'class CString' to 'char *'

The .GetBuffer(0) seems to work fine though.

please try
PSTR text=(PSTR)(LPCTSTR)m_Name;

but u can't modify text

if u want modify text please use .GetBuffer(0). After modify u must call m_Name.ReleaseBuffer()

hmmm....  I'm kinda new here too.  I think at this point, if you want to give me the points, then you have to reject happylin's answer, and then I'll post an "answer" which you can award.

On the other hand, its no big deal...
