C# to vb.net code conversion

[aswad32]

hi everyone, currently i'm doing a small code conversion from c# to vb.net, and i'm stuck with this one statement here:

Private Sub resizeWidth_MouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs){
resizingWidth = (sender == ResizeWidth);}

alright here some description:
resizingWidth is a variable type of boolean,
ResizeWidth is a variable type of UIElement.

would appreciate a simple guide and/or link that enable me to better understand the concept.

Thanks
