customize background mfc dlg

Just drawing on the dc in the PAINT method will do your job.

Here is the default PAINT method of the default dialog based MFC

Code:

	if (IsIconic())
	{
		CPaintDC dc(this); // device context for painting

		SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);

		// Center icon in client rectangle
		int cxIcon = GetSystemMetrics(SM_CXICON);
		int cyIcon = GetSystemMetrics(SM_CYICON);
		CRect rect;
		GetClientRect(&rect);
		int x = (rect.Width() - cxIcon + 1) / 2;
		int y = (rect.Height() - cyIcon + 1) / 2;

		// Draw the icon
		dc.DrawIcon(x, y, m_hIcon);
	}
	else
	{
		CDialog::OnPaint();
	}

Just replace it with

Code:

	if (IsIconic())
	{
		CPaintDC dc(this); // device context for painting

		SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);

		// Center icon in client rectangle
		int cxIcon = GetSystemMetrics(SM_CXICON);
		int cyIcon = GetSystemMetrics(SM_CYICON);
		CRect rect;
		GetClientRect(&rect);
		int x = (rect.Width() - cxIcon + 1) / 2;
		int y = (rect.Height() - cyIcon + 1) / 2;

		// Draw the icon
		dc.DrawIcon(x, y, m_hIcon);
	}
	else
	{
		CPaintDC dc(this); // device context for painting

		CRect rc;
		GetClientRect(&rc);
		dc.FillSolidRect(rc,RGB(98,84,84));
		
		CDialog::OnPaint();
	}

We just added the following lines

Code:

		CPaintDC dc(this); // device context for painting

		CRect rc;
		GetClientRect(&rc);
		dc.FillSolidRect(rc,RGB(98,84,84));
