Is it possible to convert a string into a char array?  I have tried strcpy() and many other functions with no success.

Try something like this:

      CString Str = "Test STring";
      char szStr[32];
      strcpy((char*)szStr, LPCTSTR(Str));

CString in an MFC class.  Do you mean the STL string class called "string"?  If not one of those, what do you mean by "string" ?

I'm sorry, for not phrasing my question properly.  I thought there might be a way to convert all string types to a char[] type.  I have raised the points for your troubles, sorry.

I want to convert a an LPTSTR to a WCHAR, here are my 2 variables in my program:
WCHAR LPtemp[500];
LPTSTR fName;

You can use the wide character string to multibyte character string conversion function, it is called wcstombs() and is defined in stdlib.h.

Now if the wide character string contains any characters that are not ASCII characters, the converted string will have contain multibyte characters in those places.  The OS will not be expecting those multi-byte characters in the string so it may cause problems.  Another approach that would let you avoide that problem (in favor of another) is to convert each character in the wide character string to a multibyte character using wctomb().  Then if you come to any characters that don't convert to a 1 byte multibyte character (ASCII), you can skip them.  Of course either way, the converted string is not exactly what the original was, but there is no way around that as a LPSTR type string can only store ASCII characters.

I figured out the problem, it was an extreemly simple solution compared to what I was trying to do.  I do not think the conversion I was trying is even possible.  Your answer did however lead me in the right direction, thank you very much for your help nietod!
