I use the code described on this page http://www.codeguru.com/forum/archive/index.php/t-319786.html - http://www.codeguru.com/forum/archive/index.php/t-319786.html to add a background image in my software and this solution is working fine if i don't use CXTPTabClientWnd in my software.

But if I use CXTPTabClientWnd the attach function faile to subclass m_hWndMDIClient which is already subclassed by my background painter.

How can I safley add a background image to an aplication using CXTPTabClientWnd ?

Thanks for your help

C�dric

Hello,

Override CXTPTabClientWnd and its OnFillBackground.

Thanks it is working fine.

Aditionaly to OnFillBackground I overrided OnSize to force a full redraw of the background and resize my image

afx_msg void CMDIClientWnd::OnSize(UINT nType, int cx, int cy)

{

CXTPTabClientWnd::OnSize(nType, cx, cy);

Invalidate();

}

aditional info if you try to do the same in your application:

I tester GDI and GDI+ to display my background image. GDI+ is faster give a beter result and requiere less coding.

GDI:

CDC cdc;
cdc.CreateCompatibleDC(pDC);
CBitmap * pOldBmp = cdc.SelectObject(&m_bmpBackground);

BITMAP bmp;
m_bmpBackground.GetBitmap(&bmp);

pDC->StretchBlt(rc.left, rc.top, rc.right, rc.bottom, &cdc, 0, 0, bmp.bmWidth, bmp.bmHeight, SRCCOPY);

cdc.SelectObject(pOldBmp);

GDI+:

Graphics gfx(*pDC);
Bitmap bmp(AfxGetResourceHandle(), (WCHAR *)MAKEINTRESOURCE(IDB_BACKGROUND));

gfx.DrawImage(&bmp, rc.left, rc.top, rc.Width(), rc.Height());
