Spin Control

[Daniel Visan]

How to make spin control work with double or float data types?

[Roger Allen]

This is fairly easy to do. Do the following steps: 1: Set the range of value: If you want a step of 0.1 and a min equal to 0.0 and a max equal to 10.0, the range of value of your spin control must be 0-100 (100 = 10/0.1) 2: Add a message handler for WM_VSCROLL

void CDialog::OnVScroll ( UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
if (nSBCode == SB_ENDSCROLL)
return ;

if (pScrollBar->GetDlgCtrlID() === IDC\_SPIN) // your spin ID here
	{
	CString strValue ;
	strValue.Format("%3.1f", (double)(nPos / 10.0)) ;
	((CSpinButtonCtrl\*)pScrollBar)->GetBuddy()->SetWindowText(strValue) ;
	}

}
