I create a vc6 project with a CFormView using bcgbcpro 6.70, when i add a group box to the form view,it doesn't display correctly! if i set TRANSPARENT style to it,its ok.
But I need redrawwindow, and the Group box is disappeared after redrawwindow, is it a Bug?
I need strong support about this issue,my schedule is urgent!
Thanks very much!!!!!
The source code as below:
void CRTPrintSetForm::OnRadio1()
{
RedrawWindow();
DrawPortrait();
}
void CRTPrintSetForm::OnRadio2()
{
RedrawWindow();
DrawLandScape();
}
void CRTPrintSetForm::DrawPortrait()
{
CWnd *pWnd = GetDlgItem(IDC_STATIC_PICTURE
CDC* pDC = pWnd->GetDC();
CRect rect;
pWnd->GetClientRect(&rect);
pDC->MoveTo(rect.Width()/6,0);
pDC->LineTo(5*rect.Width()/6,0);
pDC->LineTo(5*rect.Width()/6,rect.Width());
pDC->LineTo(rect.Width()/6,rect.Width());
pDC->LineTo(rect.Width()/6,0);
pWnd->ReleaseDC(pDC);
}
void CRTPrintSetForm::DrawLandScape()
{
CWnd *pWnd = GetDlgItem(IDC_STATIC_PICTURE);
CDC* pDC = pWnd->GetDC();
CRect rect;
pWnd->GetClientRect(&rect);
pDC->MoveTo(0,rect.Width()/6);
pDC->LineTo(rect.Width(),rect.Width()/6);
pDC->LineTo(rect.Width(),5*rect.Width()/6);
pDC->LineTo(0,5*rect.Width()/6);
pDC->LineTo(0,rect.Width()/6);
pWnd->ReleaseDC(pDC);//ÊÍ·ÅDC
