mfc, CStatic backround transparent

1. A true flicker free and transparent CStatic

2. Transparent Flag for CStatic in resource Editor

Is this flag supposed to work? I am trying to see what this flag does.

My text is still covering up the  background behind it when I set it to 
true.

Thanks

3. Transparent backgrounds for CStatic

4. Transparent CStatic

I have derived a CStatic control in order to add transparency and font 
control. In a first step I have override OnPaint Method to
make the control transparent :

void CStaticTest::OnPaint()
{
 CPaintDC dc(this); // device context for painting

 // Where to draw text
 CRect client_rect;
 GetClientRect(client_rect);

 // Get the caption
 CString szText;
 GetWindowText(szText);

 // Get the font
 CFont *pFont, *pOldFont;
 pFont = GetFont();
 pOldFont = dc.SelectObject(pFont);

 // Map "Static Styles" to "Text Styles"
#define MAP_STYLE(src, dest) if(dwStyle & (src)) dwText |= (dest)
#define NMAP_STYLE(src, dest) if(!(dwStyle & (src))) dwText |= (dest)

 DWORD dwStyle = GetStyle(), dwText = 0;

 MAP_STYLE( SS_RIGHT,   DT_RIGHT     );
 MAP_STYLE( SS_CENTER,   DT_CENTER     );
 MAP_STYLE( SS_CENTERIMAGE,  DT_VCENTER | DT_SINGLELINE );
 MAP_STYLE( SS_NOPREFIX,  DT_NOPREFIX     );
 MAP_STYLE( SS_WORDELLIPSIS, DT_WORD_ELLIPSIS   );
 MAP_STYLE( SS_ENDELLIPSIS,  DT_END_ELLIPSIS    );
 MAP_STYLE( SS_PATHELLIPSIS, DT_PATH_ELLIPSIS   );

 NMAP_STYLE( SS_LEFTNOWORDWRAP |
    SS_CENTERIMAGE |
    SS_WORDELLIPSIS |
    SS_ENDELLIPSIS |
    SS_PATHELLIPSIS, DT_WORDBREAK    );

 // Set transparent background
 dc.SetBkMode(TRANSPARENT);

 // Draw the text
 dc.DrawText(szText, client_rect, dwText);

 // Select old font
 dc.SelectObject(pOldFont);
}


When I try this control it is transparent but as soon as I try to change the 
text by calling SetWindowText (except in the OnInitDialog), transparency 
disappears.

ANY IDEA ?

6. Transparent CStatic on Dialog with image in background

Hi everyone!

I'm developing a little program for windows mobile (think problem
should be the same for Win32) in MFC and have problems displaying a
dialog with an JPEG-image in the background and placing some
transparent CStatic's above it.
Here is what I dit:

BOOL CMyDialog::OnEraseBkgnd(CDC * pDC)
{
	BOOL bRet = CDialog::OnEraseBkgnd(pDC);

	// draw background image
	CComPtr<IImagingFactory>pFactory;
	HRESULT hr = pFactory.CoCreateInstance(CLSID_ImagingFactory);
	IImage* pImg;
	hr = pFactory->CreateImageFromFile(_T("\\myBackImage.jpg"), &pImg);
	RECT a; a.bottom = 320; a.left = 0; a.right = 240; a.top = 0;
	pImg->Draw(pDC->m_hDC, &a, NULL);

	return bRet;
}

HBRUSH CAlarmDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

	if(nCtlColor==CTLCOLOR_STATIC)
	{
		m_nullBrush.CreateStockObject(NULL_BRUSH);//m_bgBrush;
		pDC->SetBkMode(TRANSPARENT);
		return m_nullBrush;
	}
	return hbr;
}

The reason why I have to use the CComPtr things is because
CImage::Load() is not supported by Windows Mobile, but this seems not
to be the problem. The image is drawn to the background, but the areas
of the static controls is not painted at all, meaning the background
of the statics show the previous dialog "behind it" and the areas
surrounding them show the correct image.
What am I missing here?

Thanks for any help!

8. How to build a running backround application ?

Hi,

I'm very intrested in building an application that run all the time on the 
backround (like a windows service appliaction).
When the user is typing a specific key (for example : ctrl+F1) -  it comes up

I don't care which language it is, any links to articles or any slight help, 
would be very helpfull


Thank,

Tal
