Toolbars.

I know I can obtain flat toolbars (ie style) using APIs and VB5 controls; but how can I do the same using vb6 and its controls??

whatever you can do with VB 5, you should be able to do in VB 6.
The VB 6 Toolbar (MS Common Controls) has an Appearance property that can be set to ccFlat.

I meant an internet explorer style toolbar, with buttons shadows appearing when the mouse is over...
