Conversion between C ++ Data Types

Conversion between character types:

1. LPCWSTR-> wchar_t *; LPCSTR-> char *; LPCWSTR-> const wchar_t *;

2. string-> lpwstr l "string"

3. Change _ T ("string") to char-> LPCSTR

4. CString-> LPWSTR:

Use MultiByteToWideChar
CString astring ("ssss ");
LPWSTR pointer;
Pointer = (LPWSTR) (LPCTSTR) astring;

5. LPWSTR-> CString:

LPWSTR s; CString cs = s;

6-1, int-> char *:

Char t []; int n;
Sprintf (t, "% d", n );

6-2, char *-> int

Char * s = "11"; int x;

X = atoi (s );

7-1. char []-> CString

Char code [10]; CString m_str;

M_str.Format ("% s", code );

7-2, CString-, char []

CString s1 = "ad"; char s2 [256];
Strcpy (s2, s1 );

8. CString-"void *

(Void *) LPCTSTR (buf)

9. CString-"char *

A, (LPSTR) (LPCTSTR) str

B, str. GetBuffer ();

10-1, int-, CString

CString str = "12"; int Id = 10;

Str. Format ("% s % d", str, Id );

10-2, CString-> int

Id = atoi (str );
