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

what I want to do is to somehow "import" ole32.dll into my VB app, but
I'm unsure of...

Hi,
I'm developping a form that renders differently when hovered and trigger
some processing when not hovered (leaved). The thing is, when I leave my
form and another form from my application is underneath, it works fine, but
if I leave my form and anything that is not from my application is
underneath, the Leave event does not fire until I hover something from my
application.
Here's my filtered code for the IMessageFilter (I did not...
