What is BYTE* pointing to???

If it is pointing to standart string use:

C++

BYTE* pbBuffer;
// pbBuffer initialization ...
// ...
CString sStr((char*)pbBuffer);
// sStr inculdes string pointed by pbBuffer

I desire to go in opposite direction.. from CString -> const BYTE*
Tried the following line which produces gibberish.

const BYTE* lpb = reinterpret_cast<const byte*>(&csValue);

The purpose of this is I would like to make my function call simple by
passing a CString arguement. Because the the function I'm calling requires
a const BYTE* (for some unknown reason), BYTE is defined as unsigned char
anyway. The function I'm calling is writing a value to the registry.
Any simple suggestions?

What do you need to do?
If pointer should be in the string like 0x0000ffff then use function Format.

CString local_string;
BYTE *local_pointer = (BYTE *)&local_string;
local_string.Format("%x",local_pointer);

Solution 4

Others have shown you how to convert it to a string assuming the byte* is a pointer to a character array. Here's an alternate answer where I assume that you want a string of the actual bytes the pointer is pointing to.

C++

int len = 4;
BYTE* pBytes = bytes;
CString byteString;

for(int i=0; i<len; i++)
{
    byteString.Format(L"%s %02x", byteString, *(pBytes + i));
}

Solution 7

BYTE x[5]; x[0] = 'A'; x[1] = 'B'; x[2] = 'C'; x[3] = 'D'; x[4] = '0';

CString str = TEXT("");
CString s;
for(int i=0;i<5;i++)
{
str.Format(L"%C",x[i]);
s += str;
}

AfxMessageBox(s);

Solution 2

My C++ foo is old and long unused, but this might work:

C++

BYTE* buffer;
CString sStr((char*)buffer);
// or for unicode:
CString str((const wchar_t*)buffer);

You could have easily found this with google.
