[VC++] How to Convert from CString to const char * and back

Dealing with VC++, this is only one of the painful conversions you could have to perform if you're working with CString and you need to pass down to some function (or whatever) a const char *.

Code-snippet follows (UNICODE on):

CString myString = "bollocks";

char stoneageBuffer[100];
//initialize your stoneage buffer
memset(stoneageBuffer,0,sizeof(stoneageBuffer));
sprintf(stoneageBuffer,"%S",myString);

//...

//back to CString
myString = stoneageBuffer;

Note that %S (and not %s) formatting type switches to the opposite type of character set (UNICODE if MBCS build and MBCS if UNICODE build).
