IOleUIObjInfo::GetObjectInfo
Gets size, type, name and location information about an object.
HRESULT GetObjectInfo(
DWORD dwObject,
| //32-bit object identifier
| DWORD FAR *lpdwObjSize,
| //Points to object's size
| LPTSTR FAR *lplpszLabel,
| //Points to object's label.
| LPTSTR FAR * lplpszType,
| //Points to object's "long" type
| LPTSTR FAR * lplpszShortType,
| //Points to object's "short" type
| LPTSTR FAR * lplpszLocation
| //Points to the objects source
| );
|
|
Parameters
dwObject
A unique 32-bit identifier for the object.
lpdwObjSize
[out] The object's size, in bytes, on disk. This may be an approximate value.
lplpszLabel
[out] Points to the object's label. May be NULL, which indicates that the
implementation should not fill this in.
lplpszType
[out] Points to the object's "long" type. May be NULL, which indicates that
the implementation should not fill this in.
lplpszShortType
[out] Points to the object's "short" type. May be NULL, which indicates that
the implementation should not fill this in.
lplpszLocation
[out] Points to the object's source. May be NULL, which indicates that the
implementation should not fill this in.
Return Values
S_OK
Successfully returned object information.
E_FAIL
Unable to get object information.
E_INVALIDARG
One or more invalid arguments.
E_OUTOFMEMORY
Insufficient memory.
Comment
The strings and the object's size are displayed in the object properties
"General" page.
Notes To Implementors
Your implementation of GetObjectInfo should place each of the object's attributes in the out parameters provided.
Set lpdwObjSize to (DWORD)-1 when the size of the object is unknown. Allocate all strings
(the rest of the params) with the OLE task allocator obtained via CoGetMalloc, as is standard for all OLE interfaces with [out] string parameters, or you
can simply use CoTaskMemAlloc.

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 » |
