Hello,
because of our needs I created this function
I am using a very old version of fivewin (18-01), so I don't know if it is already present in newer versions, but It looks useful so I shared it.
samples of use:
It works on Harbour and Visual Studio
can someone try it on xHarbour and bcc?
because of our needs I created this function
<div class="c" id="{CB}" style="font-family: monospace;">

  SYSTEMTIME range[2];
  long dMin = hb_pardl(2);
  long dMax = hb_pardl(3);
  int y,m,d;
  HWND hWnd = ( HWND ) hb_parfw( 1 );
  hb_dateDecode(dMin, &y, &m, &d);

samples of use:
