char yourstring[] = "this can be a string of any length";
MD5_CTX ctx;
MD5Init(&ctx, 0);
MD5Update(&ctx, (unsigned char *)yourstring, strlen(yourstring));
MD5Final(&ctx);

for(int i = 0; i < 16; i++) printf("%02X ", ctx.digest[i]);

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

<br />
class CView<br />
{<br />
  ... // lot of other stuff<br />
  CView()<br />
  {<br />
     ...// another constructor code<br />
     m_bviewLocked = false;<br />
  }<br />
<br />
  bool m_bviewLocked;<br />
}<br />
<br />
void CView::OnToolLock()<br />
{<br />
     m_bviewLocked = !m_bviewLocked; // switch between the states first call locks, second call unlocks...<br />
}<br />
<br />
WM_LBUTTONDOWN handler = where you handles the mouse click<br />
{<br />
   if( m_bviewLocked ) return 0; // we're locked - do nothing<br />
}<br />
