Can anyone tell me how to convert fro

CString to wchar_t
an
wchar_t* to CStrin

thank

I'm somewhat of a newbie myself, but wchart* is a pointer to a datatype, where CString is a class, and therefor it's (CString's) instantiation would yield and object. Therefore, you would need to create some additional code to write data (presumably your wchart data) to and from the correct CString object member variable

hope this helps.

CString str = "Hello Daniel";LPWSTR lpszW = new WCHAR[255];LPTSTR lpStr =
str.GetBuffer( str.GetLength() );int nLen = MultiByteToWideChar(CP_ACP,
0,lpStr, -1, NULL, NULL);MultiByteToWideChar(CP_ACP, 0, lpStr, -1, lpszW,
nLen);
After having done with lpszW,
use delete[] lpszW;

WCHAR wch[1024] = L"";

if defined(_UNICODE)
swprintf(wch, L"%ls", (LPCTSTR)str);
#else
swprintf(wch, L"%hs", (LPCTSTR)str);

There is no need to use GetBuffer(). If you do use it, you should call
ReleaseBuffer(). If you are going to call MultiByteToWideString() twice, you
should use the length it returns to size the array. The code you've given
could be a security risk if str changes.

Either:
CString str = "Hello Daniel";
int maxLenW = str.GetLength() * 2;
WCHAR *strW = new WCHAR[ maxLenW ];
MultiByteToWideChar(CP_ACP,0,str, -1, strW, maxLenW );

Or:
CString str = "Hello Daniel";
int lenW = MultiByteToWideChar(CP_ACP,0,str, -1, 0, 0 );
WCHAR *strW = new WCHAR[ lenW ];
MultiByteToWideChar(CP_ACP,0,str, -1, strW, lenW );

If you are using VS6, take a look at T2W and related macros. In VS7, you can use CT2W (T2W
has been deprecated).

Seems to me like Jagadeesh's way is fairly straight forward. CString.GeBuffer(CString.GetLength()) is the method I was looking for to get access to the Object's data buffer.

Thanks everyone for your help.
