GetHGlobalFromStream
Returns the global memory handle to a stream that was created using the CreateStreamOnHGlobal function.
HRESULT GetHGlobalFromStream(
IStream * pstm,
| //Points to the stream object
| HGLOBAL * phglobal
| //Points to the current memory handle for the specified stream
| );
|
|
Parameters
pstm
Points to the stream object previously created by a call to the CreateStreamOnHGlobal function.
phglobal
Points to the current memory handle used by the specified stream object.
Return Values
S_OK
Indicates the handle was successfully returned.
E_INVALIDARG
Indicates invalid value specified for the pstm parameter. It can also indicate that the stream object passed in is not one
created by a call to the CreateStreamOnHGlobal function.
Comments
The handle this function returns may be different from the original handle due
to intervening GlobalRealloc calls.
This function only works within the same process from which the byte array was
created.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

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 » |
