Windows Mobile 6.5
A version of this page is also available for
4/8/2010

This function retrieves device-specific information about a remote Windows Embedded CE–based device.


INT CeGetDesktopDeviceCaps(
  INT nIndex 
);

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:

RC_BANDING (Requires banding support)

RC_BITBLT (Capable of transferring bitmaps)

RC_BITMAP64 (Capable of supporting bitmaps larger than 64K)

RC_DI_BITMAP (Capable of supporting the SetDIBits and GetDIBits functions)

RC_DIBTODEV (Capable of supporting the SetDIBitsToDevice function)

RC_FLOODFILL (Capable of performing flood fills)

RC_GDI20_OUTPUT (Capable of supporting features of 16-bit Windows 2.0)

RC_PALETTE (Specifies a palette-based device)

RC_SCALING (Capable of scaling)

RC_STRETCHBLT (Capable of performing the StretchBlt function)

RC_STRETCHDIB (Capable of performing the StretchDIBits function)

CURVECAPS
