GetHGlobalFromILockBytes
Returns a global memory handle to a byte array object created using the CreateILockBytesOnHGlobal function.
HRESULT GetHGlobalFromILockBytes(
ILockBytes * pLkbyt,
| //Points to the byte array object
| HGLOBAL * phglobal
| //Points to the current memory handle for the specified byte array
| );
|
|
Parameters
pLkbyt
Points to the byte array object previously created by a call to the CreateILockBytesOnHGlobal function.
phglobal
Points to the current memory handle used by the specified byte array object.
Return Values
S_OK
Indicates the handle was returned successfully.
E_INVALIDARG
Indicates invalid value specified for the pLkbyt parameter. It can also indicate that the byte array object passed in is not
one created by the CreateILockBytesOnHGlobal function.
Comments
The handle this function returns might be different from the original handle
due to intervening calls to the GlobalRealloc function.
The contents of the returned memory handle can be written to a clean disk
file, and then opened as a storage object using the StgOpenStorage function.
This function only works within the same process from which the byte array was
created.

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 » |
