Hi,<o:p></o:p>
Want
to expose a method of COM Friendly class (managed class in c#), to an unmanaged
method which should accept pointer to LPVOID.<o:p></o:p>
<o:p> </o:p>
The exposed method should be <o:p></o:p>
HRESULT Method(LPVOID *data);<o:p></o:p>
<o:p> </o:p>
How do I write a managed code which will result exactly to
the above unmanaged code.<o:p></o:p>
I have tried the following:<o:p></o:p>
<o:p> </o:p>
a. <o:p></o:p>
public int Method(IntPtr a)<o:p></o:p>
{<o:p></o:p>
-----<o:p></o:p>
}<o:p></o:p>
b.<o:p></o:p>
public int Method(ref IntPtr a)<o:p></o:p>
{<o:p></o:p>
----<o:p></o:p>
}<o:p></o:p>
Using TlbExp.exe I exported the managed code to Type Library
and it looks like following:<o:p></o:p>
Int Method(long *a)<o:p></o:p>
{<o:p></o:p>
-----<o:p></o:p>
}<o:p></o:p>
<o:p> </o:p>
Can anybody help me getting LPVOID instead of long *<o:p></o:p>
<o:p> </o:p>
Thanks,<o:p></o:p>
Hemant<o:p></o:p>
