Hi SuperMario,
 
Yeah, I've looked at the button sample and have tried it in my own app. It works ok, but I can still faintly see the outline of the button even though it is being rendered transparently in flat style.
 
It's as if the background of the button isn't getting the right brush offset of the background image. I've posted my OnCtlColor routine if you can see anything that looks off.
 

HBRUSH CHDMSDiag::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

{

HBRUSH hbr;

 

if( nCtlColor == CTLCOLOR_STATIC || nCtlColor == CTLCOLOR_BTN || nCtlColor == CTLCOLOR_DLG || nCtlColor == CTLCOLOR_EDIT )

{

if(img){

m_brush = CreatePatternBrush(img); // Previously created CImage

if (pWnd->m_hWnd != this->m_hWnd)

{

CXTPWindowRect rcPaint(pWnd);

CXTPWindowRect rcBrush(m_hWnd);

HDC hDC = pDC->m_hDC;

::SetBrushOrgEx(hDC, rcBrush.left - rcPaint.left, rcBrush.top - rcPaint.top, NULL);

::SetBkMode(hDC, TRANSPARENT);

if(nCtlColor == CTLCOLOR_STATIC){

if(pWnd->m_hWnd != this->GetDlgItem(IDC_DRIVE2_ICON)->GetSafeHwnd()

&& pWnd->m_hWnd != this->GetDlgItem(IDC_DRIVE1_ICON)->GetSafeHwnd()

&& pWnd->m_hWnd != this->GetDlgItem(IDC_DRIVE_1)->GetSafeHwnd()){

pDC->SetBkMode(TRANSPARENT);

::SetTextColor(hDC, RGB(255, 255, 255));

return (HBRUSH)GetStockObject(NULL_BRUSH);

}else

int test = 0;

}

else

::SetTextColor(hDC, RGB(255, 255, 255));

}

}

return m_brush;

}

else

{

hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

}

return hbr;

}

Hi,
 
Whats the best control to use for displaying a transparent .png file over top of a background image.
 
I paint a custom .png file to the background of a dialog inside onpaint and have successfully used the OnCtlColor routine to return the correct brush to make the CJ buttons transparent, but I'd like to know the best control to paint a transparent image.
 
I've tried using the standard MFC CStatic class, but the transparency isn't working with CStatic::SetBitmap
 
Thanks,
 
Jai
