CreateIconFromResourceEx

The CreateIconFromResourceEx function creates an icon or cursor from resource bits describing the icon.

HICON CreateIconFromResourceEx(
  PBYTE pbIconBits, // pointer to icon or cursor bits
  DWORD cbIconBits, // number of bytes in bit buffer
  BOOL fIcon,       // icon or cursor flag
  DWORD dwVersion,  // format version
  int cxDesired,    // desired width of icon or cursor
  int cyDesired,    // desired height of icon or cursor
  UINT uFlags       // load resource flags
);
 

Parameters

pbIconBits

Pointer to a buffer containing the icon or cursor resource bits. These bits are typically loaded by calls to the LookupIconIdFromDirectoryEx and LoadResource functions.

cbIconBits

Specifies the size, in bytes, of the set of bits pointed to by the pbIconBits parameter.

fIcon

Specifies whether an icon or a cursor is to be created. If this parameter is TRUE, an icon is to be created. If it is FALSE, a cursor is to be created.

dwVersion

Specifies the version number of the icon or cursor format for the resource bits pointed to by the pbIconBits parameter. This parameter can be one of the following values:

Format	dwVersion
Windows 2.x	0x00020000
Windows 3.x	0x00030000

All Win32-based applications use the Windows 3.x format for icons and cursors.

cxDesired

Specifies the desired width, in pixels, of the icon or cursor. If this parameter is zero, the function uses the SM_CXICON or SM_CXCURSOR system metric value to set the width.

cyDesired

Specifies the desired height, in pixels, of the icon or cursor. If this parameter is zero, the function uses the SM_CYICON or SM_CYCURSOR system metric value to set the height.

uFlags

Specifies a combination of the following values:

Value	Meaning
LR_DEFAULTCOLOR	Uses the default color format.
LR_MONOCHROME	Creates a monochrome icon or cursor.

Return Values

If the function succeeds, the return value is a handle to the icon or cursor.

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

Remarks

The CreateIconFromResourceEx, CreateIconFromResource, CreateIconIndirect, GetIconInfo, and LookupIconIdFromDirectoryEx functions allow shell applications and icon browsers to examine and use resources from throughout the system.
