How to convert a 64-bit integer to a wide string

The solution is as follows:

 

1. First, use sprintf to convert to char * (for security consideration, use springf_s or snprintf)

2. Use multibytetowidechar to convert the converted string to a wide character (UNICODE)

 

Note that for non-int64 types, you can use wsprintf () to directly format the data into a wide character set. However, wsprintf does not support 64-bit integer types.

 

CodeSample:

 

Char buff [1024];

Securezeromemory (buff, sizeof (buff ));

 

 

Sprintf (buff, format, source );

 

Wchar_t Dest [1024];

Multibytetowidechar (cp_acp, 0, buff,-1, DEST, 1024 );
