1/6/2010
This function retrieves device-specific information about a remote Windows Embedded CE–based device.
Syntax
INT CeGetDesktopDeviceCaps(
INT nIndex
);
Parameters
nIndex
[in] Specifies the item to return. It is one of the following values.Value Description DRIVERVERSION
Returns the device driver version.
TECHNOLOGY
Returns the device technology (DT). It is one of the following values:
DT_PLOTTER (Vector plotter)
DT_RASDISPLAY (Raster display)
DT_RASPRINTER (Raster printer)
DT_RASCAMERA (Raster camera)
DT_CHARSTREAM (Character stream)
DT_METAFILE (Metafile)
DT_DISPFILE (Display file)
If the hdc parameter identifies the device context of an enhanced metafile, the device technology is that of the referenced device as given to the CreateEnhMetaFile function. To determine whether it is an enhanced metafile device context, use the GetObjectType function.
HORZSIZE
Returns the width, in millimeters, of the physical screen.
VERTSIZE
Returns the height, in millimeters, of the physical screen.
HORZRES
Returns the width, in pixels, of the screen.
VERTRES
Return the height, in raster lines, of the screen.
BITSPIXEL
Returns the number of adjacent color bits for each pixel.
PLANES
Returns the number of color planes.
NUMBRUSHES
Returns the number of device-specific brushes.
NUMPENS
Returns the number of device-specific pens.
NUMMARKERS
Returns the number of device-specific markers.
NUMFONTS
Returns the number of device-specific fonts.
NUMCOLORS
Returns the number of entries in the device's color table, if the device has a color depth of no more than 8 bits per pixel. For devices with greater color depths, –1 is returned.
ASPECTX
Returns the relative width of a device pixel used for line drawing.
ASPECTY
Returns the relative height of a device pixel used for line drawing.
ASPECTXY
Returns the diagonal width of the device pixel used for line drawing.
PDEVICESIZE
Reserved.
CLIPCAPS
Returns the flag that indicates the clipping capabilities of the device. If the device can clip to a rectangle, it is 1. Otherwise, it is 0.
PHYSICALWIDTH
For printing devices, returns the width of the physical page, in device units. For example, a printer set to print at 600 dpi on 8.5"x11" paper has a physical width value of 5100 device units. Note that the physical page is almost always greater than the printable area of the page, and never smaller.
PHYSICALHEIGHT
For printing devices, returns the height of the physical page, in device units. For example, a printer set to print at 600 dpi on 8.5"x11" paper has a physical height value of 6600 device units. Note that the physical page is almost always greater than the printable area of the page, and never smaller.
PHYSICALOFFSETX
For printing devices, returns the distance from the left edge of the physical page to the left edge of the printable area, in device units. For example, a printer set to print at 600 dpi on 8.5"x11" paper, that cannot print on the leftmost 0.25" of paper, has a horizontal physical offset of 150 device units.
PHYSICALOFFSETY
For printing devices, returns the distance from the top edge of the physical page to the top edge of the printable area, in device units. For example, a printer set to print at 600 dpi on 8.5"x11" paper, that cannot print on the topmost 0.5" of paper, has a vertical physical offset of 300 device units.
RASTERCAPS
Returns the value that indicates the raster capabilities of the device, as shown in the following list:
