Background Picture on Dialog

[WXP]

Hey !

I Created a Dialog Based App.
And i put a picture box on the background and other controls on it. The trouble is they disappear under the picture.
So i changed the TAB Order but when a window comes over my app the button disappear again !!

How is it possible to put a picture on the background without a picture box ?

OR how it is possible to have my controls over eveything ?

Thanx

That's no way to do things, pal! A picture box is both inefficient and darn, pal. :-D

Now, Uncle Xeon to the fire scene rescue!

First, in your OnInitDialog(), code the following and paste everything just above the 'return TRUE;' statement, but below everything else:

CBitmap bitmap;
bitmap.LoadBitmap(IDB_YOURBITMAP);

CClientDC dc(this);
CRect rcRect;
GetClientRect(rcRect);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SelectObject(&bitmap);

dc.BitBlt(0,0,rcRect.Width(), rcRect.Height(),&memDC,0,0,SRCCOPY);




Now, that's all to it! But preferably, u should add a windows message handler call WM_ERASEBKGND and add the code above to it. Now, don't treat me to a buffet though. :-D That's too grand! :-D

It's not working Xeon.. sorry..

My Dialog do not have my pic on the background.. not even a pixel !

anyother idea ?


BOOL CGPIBMultimeterDlg::OnInitDialog()
{
CDialog::OnInitDialog();

// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon

// Some of my code...

CBitmap bitmap;
bitmap.LoadBitmap(IDB_INTERFACE_BITMAP);
CClientDC dc(this);
CRect rcRect;
GetClientRect(rcRect);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SelectObject(&bitmap);
dc.BitBlt(0,0,rcRect.Width(), rcRect.Height(),&memDC,0,0,SRCCOPY);

return TRUE; // return TRUE unless you set the focus to a control
}

You can do your displaying of bitmap inside you dialog's OnDraw(...) function.

class CGPIBMultimeterDlg : public CDialog
//....
//{{AFX_MSG(CGPIBMultimeterDlg )
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
//}}AFX_MSG
//....

BEGIN_MESSAGE_MAP(CGPIBMultimeterDlg, CDialog)
//{{AFX_MSG_MAP(CMedStatix)
ON_WM_ERASEBKGND()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

BOOL CGPIBMultimeterDlg::OnEraseBkGnd(CDC* pDC)
{
CBitmap bitmap;
bitmap.LoadBitmap(IDB_INTERFACE_BITMAP);
CRect rcRect;
GetClientRect(rcRect);
CDC memDC;
memDC.CreateCompatibleDC(pDC);
memDC.SelectObject(&bitmap);
dc.BitBlt(0,0,rcRect.Width(),
rcRect.Height(),&memDC,0,0,SRCCOPY);
return TRUE; // Don't call base class
}




That's the way

But another hint;-)
You should make
the CBitmap bitmap;
as a member of your dialog and load the bitmap only one time in the OnInitDialog
