[win32 API] How to prevent a dialog from using winXP visual themes ?

Hi,

I would like to know how you managed to prevent mIRC dialogs from using the winXp visual themes with MDX.

I know you had to use a manifest with previous version of mdx, but not with the actual.

I tried some win32 functions, but none seem to work. I encounter some problems when a create a flat radio button control on a mIRC window, since the text and bkg is all black because of the theme.

Is it possible to remove the theme from an existing mIRC window (or just a control). If so, how ?

Thanks.
