Re: [Dev-C++] Dsiplaying images

Hi,

I think you're using a user defined function. That function is not in
the Windows API reference. Instead you can use LoadImage(). See below.

The LoadImage function loads an icon, cursor, or bitmap.

HANDLE LoadImage(

    HINSTANCE hinst, 	// handle of the instance that contains the image
    LPCTSTR lpszName,	// name or identifier of image
    UINT uType,	// type of image
    int cxDesired,	// desired width
    int cyDesired,	// desired height
    UINT fuLoad	// load flags
   );	
 

Parameters

hinst

Identifies an instance of the module that contains the image to be
loaded. To load an OEM image, set this parameter to zero. 

lpszName

Identifies the image to load. 

If the hinst parameter is non-NULL and the fuLoad parameter does not
include LR_LOADFROMFILE, lpszName is a pointer to a null-terminated
string that contains the name of the image resource in the hinst
module.
If hinst is NULL and LR_LOADFROMFILE is not specified, the low-order
word of this parameter must be the identifier of the OEM image to load.
The OEM image identifiers are defined in WINUSER.H and have the
following prefixes:

Prefix	Meaning
OBM_	OEM bitmaps
OIC_	OEM icons
OCR_	OEM cursors
 

Windows 95: If the fuLoad parameter includes the LR_LOADFROMFILE value,
lpszName is the name of the file that contains the image. 
Windows NT: LR_LOADFROMFILE is not supported.

uType

Specifies the type of image to be loaded. This parameter can be one of
the following values:

Value	Meaning
IMAGE_BITMAP	Loads a bitmap.
IMAGE_CURSOR	Loads a cursor.
IMAGE_ICON	Loads an icon.
 

cxDesired

Specifies the width, in pixels, of the icon or cursor. If this
parameter is zero and the fuLoad parameter is LR_DEFAULTSIZE, the
function uses the SM_CXICON or SM_CXCURSOR system metric value to set
the width. If this parameter is zero and LR_DEFAULTSIZE is not used,
the function uses the actual resource width. 

cyDesired

Specifies the height, in pixels, of the icon or cursor. If this
parameter is zero and the fuLoad parameter is LR_DEFAULTSIZE, the
function uses the SM_CYICON or SM_CYCURSOR system metric value to set
the height. If this parameter is zero and LR_DEFAULTSIZE is not used,
the function uses the actual resource height. 

fuLoad

Specifies a combination of the following values:

Value	Meaning
LR_DEFAULTCOLOR	The default flag; it does nothing. All it means is "not
LR_MONOCHROME".
LR_CREATEDIBSECTION	When the uType parameter specifies IMAGE_BITMAP,
causes the function to return a DIB section bitmap rather than a
compatible bitmap. This flag is useful for loading a bitmap without
mapping it to the colors of the display device.
LR_DEFAULTSIZE	Uses the width or height specified by the system metric
values for cursors or icons, if the cxDesired or cyDesired values are
set to zero. If this flag is not specified and cxDesired and cyDesired
are set to zero, the function uses the actual resource size. If the
resource contains multiple images, the function uses the size of the
first image. 
LR_LOADFROMFILE	Loads the image from the file specified by the lpszName
parameter. If this flag is not specified, lpszName is the name of the
resource.
LR_LOADMAP3DCOLORS	Searches the color table for the image and replaces
the following shades of gray with the corresponding 3D color:
 

Color	Replaced with
Dk Gray, RGB(128,128,128)	COLOR_3DSHADOW
Gray, RGB(192,192,192)	COLOR_3DFACE
Lt Gray, RGB(223,223,223)	COLOR_3DLIGHT
 

LR_LOADTRANSPARENT	Retrieves the color value of the first pixel in the
image and replaces the corresponding entry in the color table with the
default window color (COLOR_WINDOW). All pixels in the image that use
that entry become the default window color. This value applies only to
images that have corresponding color tables. If fuLoad includes both
the LR_LOADTRANSPARENT and LR_LOADMAP3DCOLORS values, LRLOADTRANSPARENT
takes precedence. However, the color table entry is replaced with
COLOR_3DFACE rather than COLOR_WINDOW.
LR_MONOCHROME	Loads the image in black and white.
LR_SHARED	Shares the image handle if the image is loaded multiple
times. If LR_SHARED is not set, a second call to LoadImage for the same
resource will load the image again and return a different handle.Do not
use LR_SHARED for images that have non-standard sizes, that may change
after loading, or that are loaded from a file.
 

Return Values

If the function succeeds, the return value is the handle of the newly
loaded image.
If the function fails, the return value is NULL.
