I am using gdi+ for image format checking.
It is really surprising that gdi+
Image img(path);
does not throw exception when a device is removed.
for example, I am checking a list of image files on a removable device.

The FromHbitmap method makes a copy of the GDI bitmap; so you can release the incoming GDI bitmap using the GDIDeleteObject method immediately after creating the new Image.

int y1 = rnd.Next(ClientRectangle.Top,…

I need to fill a CImageList with a number of bitmaps which are stored in separate bmp files (rather than as a single bmp with numerous parts). I assume I need to create a CBitmap so I can call the Add method of CImageList. So how might one create a CBitmap object using only MFC Resource IDs?
