I created a theme for my radbuttons i use throughout my win app. unfortunately i does not show up at all even so i followed your instructions pdf (i does not show quite the steps about embeding it as from a resource) and i looked at your thememanagerexample which just errors out all the time on my computer and since i have no time to get it so it runs i could not get much out of it either. and yes i have the theme file in a resources folder and i set it embed as resource in the properties. in the thememanager however it always says "Object not found" . I see my theme applied to the buttons but as soon as i run the solution the theme gets not picked up. i need it to show up no matter if it is on my computer or on a client where i install the solution the theme has to be always available. Since i can not use the add as file because it errors out on other computrs i need to use it as resoucre. please get back to me asap!i am using Q1 2007 and C#
