Hi,
Following code change the windows appearance through VB6 API. When your application run it change the fonts of windows appearence (all open windows). You can tweak it for more options such as color scheme, pictures and others.
In order to test the code open a project in VB6 then take a combo box on the form and paste the code in the form. Run & vola.
