CreateIcon info  Overview  Group

The CreateIcon function creates an icon that has the specified size, colors, and bit patterns.

HICON CreateIcon(

Parameters

hInstance

Identifies the instance of the module creating the icon.

nWidth

Specifies the width, in pixels, of the icon.

nHeight

Specifies the height, in pixels, of the icon.

cPlanes

Specifies the number of planes in the XOR bitmask of the icon.

cBitsPixel

Specifies the number of bits per pixel in the XOR bitmask of the icon.

lpbANDbits

Points to an array of bytes that contains the bit values for the AND bitmask of the icon. This bitmask describes a monochrome bitmap.

lpbXORbits

Points to an array of bytes that contains the bit values for the XOR bitmask of the icon. This bitmask describes a monochrome or device-dependent color bitmap.

Return Values

If the function succeeds, the return value is the handle to an icon.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

The nWidth and nHeight parameters must specify a width and height supported by the current display driver, because the system cannot create icons of other sizes. To determine the width and height supported by the display driver, use the GetSystemMetrics function, specifying the SM_CXICON or SM_CYICON value.

CreateIcon applies the following truth table to the AND and XOR bitmasks:
