Hello.
Is possible to know when another window outside of our app has been open or is about to open?.
Thanks in advance

Is there a way to create a disabled image from an image in a CImageList?
(It's not an image list for a toolbar).

DrawState with DSS_DISABLED should be OK. Note that this function operates on a device context, you'll need to copy the imagelist into a bitmap, call DrawState, then copy back.

Sorry if this is a stupid question but how do I get an image in the image list into a bitmap. I had a look at the interface for image list and couldn't see anything like that

How do you initialize your imagelist? Is it one wide bitmap stored as resource, or something else?

Thanks for helping me out with this. The situation is this:
I am in the middle of doing an owner-drawn button that I want to allow bitmaps or icons to be added, which I can do by adding either to a CImageList. The problem so far is the disabled image. I have two functions which are illustrated below. The first is for adding the bitmap, which works for standard and disabled images and the second which works for the standard image but requires the addition of the disabled image. I apologise if the code is a bit spaghetti, but I am working towards having the ability if having multiple images set, but I'm not there yet 
BOOL SSLButtonEx::SetButtonBitmap(UINT nResourceID, COLORREF crMask) {
BOOL bReturn = m_bmpImage.LoadBitmap (nResourceID);
if (TRUE == bReturn) {
m_bmpImage.GetObject (sizeof m_bmp, &m_bmp);
m_nImageWidth = m_bmp.bmWidth;
m_nImageHeight = m_bmp.bmHeight;
bReturn = m_imageList.Create (nResourceID, m_bmp.bmWidth, 1, crMask);
if (TRUE == bReturn) {
if (m_imageList.Add (&m_bmpImage, crMask) > -1) {
m_bImageLoaded = TRUE;
}
else {
m_bImageLoaded = FALSE;
}
m_crMask = crMask;
HBITMAP bmpTemp;
COLORMAP mapColour;
mapColour.from = crMask;
mapColour.to = RGB(255,255,255);
bmpTemp = (HBITMAP)::CreateMappedBitmap (AfxGetApp()->m_hInstance,
nResourceID, IMAGE_BITMAP, &mapColour, 1);
m_hbmpDisabled = (HBITMAP)::CopyImage(bmpTemp, IMAGE_BITMAP,
m_nImageWidth, m_nImageHeight, LR_COPYDELETEORG);
}
else {
m_bImageLoaded = FALSE;
}
}
return bReturn;
}
BOOL SSLButtonEx::SetButtonIcon(UINT nResourceID, COLORREF crMask) {
BOOL bReturn = FALSE;
HINSTANCE hInstance = AfxFindResourceHandle (MAKEINTRESOURCE (nResourceID), RT_GROUP_ICON);
m_hIcon = (HICON)::LoadImage (hInstance, MAKEINTRESOURCE (nResourceID), IMAGE_ICON, 0, 0, 0);
if (NULL != m_hIcon) {
m_crMask = crMask;
ICONINFO iconInfo;
ZeroMemory (&iconInfo, sizeof (ICONINFO));
bReturn = ::GetIconInfo (m_hIcon, &iconInfo);
if (TRUE == bReturn) {
m_nImageWidth = iconInfo.xHotspot * 2;
m_nImageHeight = iconInfo.yHotspot * 2;
::DeleteObject(iconInfo.hbmMask);
::DeleteObject(iconInfo.hbmColor);
bReturn = m_imageList.Create (m_nImageWidth, m_nImageHeight, ILC_COLOR32 | ILC_MASK, 1, 1);
if (TRUE == bReturn) {
if (m_imageList.Add (m_hIcon) > -1) {
m_bImageLoaded = TRUE;
}
else {
m_bImageLoaded = FALSE;
}
}
}
}
return bReturn;
}

Two solutions are possible:
1) you can use ImageList_GetImageInfo or CImageList::GetImageInfo. This gives you underlying HBITMAP (all images in the list stored on single bitmap), which you can pass to DrawState. You should perform this on a copy of original imagelist, but that's an easy part - just use ImageList_Copy or its MFC counterpart.
2) you have icon/bitmap handle in SetButtonXXX methods. For each 'source' image create appropriate 'disabled' one, then add this to second imglist.

Thanks for sticking with me on this one
In SetButtonIcon I have the following to create a copy of the bitmap:
IMAGEINFO imgInfo;
m_imageList.GetImageInfo (0, &imgInfo);
m_hbmpDisabled = (HBITMAP)::CopyImage (imgInfo.hbmImage, IMAGE_BITMAP,
m_nImageWidth, m_nImageHeight, LR_COPYDELETEORG);
Then in DrawItem I use the following to draw it as a disabled image:
pDC->DrawState (CPoint (3, 3), CSize (m_nImageWidth, m_nImageHeight),
m_hbmpDisabled, DST_BITMAP | DSS_DISABLED);
Unfortunately this just draws a grey square, rather than the disabled image. The SetButtonBitmap function uses a similar process, but uses CreateMappedBitmap to map the mask colour to white. This bitmap is then copied into m_hbmpDisabled using ::CopyImage.
Presumably this is the step that is missing in SetButtonIcon, but how can I use CreateMappedBitmap without a bitmap resource id?

So SetButtonBitmap works OK? If yes, you should try to pass DST_ICON flag to DrawState inside SetButtonIcon. No CopyImage call would be required in this case.

Thanks for your email yesterday.
Finally I've got it cracked
I add the bitmap ot icon into the image list in SetButtonBitmap or SetButtonIcon respectively, and then in DrawItem I use ExtractIcon and treat any image in the image list, regardless of source, as an icon. That way I don't need to worry about a copy of the bitmap or anything. This opens the door to multiple images
I feel like I've broken the back of this project. Hopefully before long I'll publish the article and code.
Thanks for your help.

I want to assign my own data with he file. And want to store it as custom attribute.
If there is any such way then, please tell me whether there is any direct API to do so.
Thank you.

You could try the 'alternate data streams' feature. Check KB article Q105763 for details.

Hello,
I'm working on a Dialogbased Windows CE application. The application communicates with a device. It's the intention that when I type in some digits in an EditBox and press Enter, the string of digits will be send to the device. When I use an OnChangeEDit Event, every time I type in a digit the data is send. How can I avoid this so it will only send the data when I press Enter?

On the very first page of CodeProject there's a 'Latest tutorials' section. You can find the link to timers tutorial there.

I would like to know if in vc++ we could choose an option which make the debugger more accurate. I already know that there is a difference between Debug and Release.
thanks in advance
