Converting twip?

[ericJA]

I know a twip is 1/20 of a point but what is a twip to a pixel? and a point
to a pixel conversion?

Thanks

Check out the Screen.TwipsPerPixelX Screen.TwipsPerPixelY.

Why not set the Scale property on your form to pixels instead of twips.

Here are some snippets of code copied from above. You may also need to use MapDialogRect() or GetDialogBaseUnits().



int m_nLogX;
int m_nLogY;

// To convert grid rect from twips to DC units you need
// pixels per inch.
CDC* pDC = GetDC();
m_nLogX = pDC->GetDeviceCaps(LOGPIXELSX);
m_nLogY = pDC->GetDeviceCaps(LOGPIXELSY);
ReleaseDC(pDC);

// Create invisible edit control.
m_edit.Create(WS_CHILD|ES_MULTILINE|ES_WANTRETURN,
CRect(0,0,0,0), this, GetDlgCtrlID());

// Adjust for border height and convert from twips to screen
// units.
m_edit.MoveWindow(((GetCellLeft() - m_lBorderWidth) *
m_nLogX)/1440,
((GetCellTop() - m_lBorderHeight) * m_nLogY)/1440,
(GetCellWidth()* m_nLogX)/1440,
(GetCellHeight()* m_nLogY)/1440, FALSE);
m_edit.ShowWindow(SW_SHOW);
m_edit.SetFocus();
