CreateIconFromResource
The CreateIconFromResource function creates an icon or cursor from resource bits describing the icon.
HICON CreateIconFromResource(
PBYTE presbits,
| // pointer to icon or cursor bits
| DWORD dwResSize,
| // number of bytes in bit buffer
| BOOL fIcon,
| // icon or cursor flag
| DWORD dwVer
| // Windows format version
| );
|
|
Parameters
presbits
Points to a buffer containing the icon or cursor resource bits. These bits are
typically loaded by calls to the LookupIconIdFromDirectory (in Windows 95 you can also call LookupIconIdFromDirectoryEx) and LoadResource functions.
dwResSize
Specifies the size, in bytes, of the set of bits pointed to by the presbits 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.
dwVer
Specifies the version number of the icon or cursor format for the resource
bits pointed to by the presbits parameter. This parameter can be one of the following values:
Format
| dwVer
| Windows 2.x
| 0x00020000
| Windows 3.x
| 0x00030000
|
All Microsoft Win32-based applications use the Windows 3.x format for icons and cursors.
Return Values
If the function succeeds, the return value is the handle to the icon or cursor.
If the function fails, the return value is NULL. To get extended error
information, call GetLastError.
Remarks
The CreateIconFromResource, CreateIconIndirect, GetIconInfo, and LookupIconIdFromDirectory functions (and in Windows 95 the CreateIconFromResourceEx and LookupIconIdFromDirectoryEx functions) allow shell applications and icon browsers to examine and use
resources from throughout the system.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
