error C2664: cannot convert argument 1 from 'CString' to 'const char *'

int nLen = str.GetLength();

char *ch = new char[nLen];

  WideCharToMultiByte(CP_ACP, 0, str, -1, ch, nLen + 1, NULL, NULL);

  --- << ch 사용 >> ---

delete[] ch;

C2665: 'AfxMessageBox' : none of the 2 overloads could convert all the argument types

(1)

You may, although I doubt this, have to scope it globally. To do that, try

::AfxMessageBox("Camera have no connection",MB_OK|MB_ICONSTOP);

(2)

The other is that use are building for unicode and it thinks the string is multi-byte. To do that, try

AfxMessageBox( L"Camera have no connection",MB_OK|MB_ICONSTOP);

I'm out of town, on my Mac, so I can't test this. But I have been stuck in the office on weekends so I figured I'd offer up two things to try.

min() 이 부분이 

minwindef.h

#define min(a,b)            (((a) < (b)) ? (a) : (b))

위와 같이 연결되니까, 당연히 (a,b)가 없다고 에러가 나올수 밖에.

windows.h 추가하기 전에 #NOMINMAX 해버리면, min, max 정의하지 않으므로 OK
