Varible Naming Conventions

Here is one link:
http://home.jtan.com/~gregleg/hungarian.html
but there are as many naming conventions as there are programmers - you should find one that you can use (if you're fitting into a team, you won't have much choice).  A web search should throw up plenty.  

I suppose that dw is a DWORD (32 bit unsigned int) and that str is a string.  You really need to look at the declarations to find out.

"sz" and "Str" usually get prefixed to variables that are meant to be strings;

"dw" is for DWORD

Also in (fairly) common use:

"n" for integer
"l" for long
"tag" for a struct
"u"  for unsigned int
"ul" for unsigned long

ets., etc., etc....

you can extend this convention by using postfix notation

int A(char* szInit_in, DWORD* dwParam_out)

or

CDialog dlgProperty;
HWND dlgProperty_hwnd; // hwnd of this Dialog

and so on

I think you forgot this question. I will ask Community Support to close it unless you finalize it within 7 days. Unless there is objection or further activity,  I will suggest to refund the points and PAQ at zero points since nobody had a complete answer for you.
