Hello all,
I have a form class that implements the imessagefilter interface
public class frmMain : System.Windows. Forms.Form, IMessageFilter
I also have this implemented
bool IMessageFilter. PreFilterMessag e( ref Message m )
This class actually interacts with the twain driver and that's why I need
the messagefilter, to get the twain messages. When I call this class as an
mdichild, I am not able to acquire images. I assume, this is because the
messages don't reach the child window. Is this right ? In that case, how can
we overcome this ? Should the parent also implement imessagefilter ? And
then how can the parent window pass the messages to the child window ?
Thanks
Seesharp

Seesharp,
You can have the parent implement IMessageFilter and then have some sort
of callback/event mechanism of your own design that will notify listeners
when twain messages come in through the message pump.
Hope this helps.

Hi there,
I want to implement the COM interface IMessageFilter from my VB.NET
application. I realize that it's inside ole32.dll, and that ole32.dll
doesn't have a type library inside of it, so I'm unsure if this is
even possible. I'm pretty green to VB.NET, and .NET in general, so
would anyone be able to give me a little push? ...

IMessageFilter interface allows one to capture messages before they are

I want to have a form that accepts keypresses. The controls other than the form should not receive any of the user input. I have implemented it using IMessageFilter but now just now I discovered about KeyPreview.
What is the difference between IMessageFilter and KeyPreview? Is there a significant benefit using one way than the other?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
