im using radio button array with button appearence.
Im just wondering if there is a easy way programtically to enhance the
button look with such things a gradient color fills and effects and
stuff, without having to resort to using bitmaps or images for
backgrounds ? Im mostly interested in adding something like a metalic
gradient effect to the buttons and the form background.

Incidently is it possible to perhaps use a vector based image format
that can be resized without pixelisation as a button or form
backgorund.
I wish I knew the exact answer to your queston. :)
However, some thoughts on the general idea...
As far as doing something vector-based, it seems to me that you could instead of using a Bitmap, use a Metafile which is essentially a vector-based thing. Or for that matter, I suppose you could override the OnPaint() method and just always draw what you want. As far as drawing the kinds of things you're talking about goes, I have not played with it yet, but I seem to recall a variety of "fancy" drawing commands from GDI+, which I think is supported from .NET.
Also, I haven't had a chance to try to learn about the whole "VisualStyles" stuff, but it sure seems to me that this is exactly what they exist for. To provide alternate visual styles for your controls. I could be wrong, but perhaps if you look into that section of the .NET Framework classes, there will be some guidance as to how to customize the visual style of your control.
and can images and bitmaps be embedded into the application when used
for buttons and forms or must they be located in the local app
directory ?
Well, you can include a bitmap as a resource in the application, which you can then use to create a Bitmap instance using the Bitmap.FromResource() method. It would be a little harder to create a Metafile instance from a resource, but I believe you could do it by storing the metafile saved as a file in the resources as a plain binary resource, then use that to create a MemoryStream, then use that with Metafile.FromStream() to create the metafile instance. If there's some other "image" you're thinking of that you want to store in the application, you should probably elaborate on that. Other than bitmaps and metafiles, the only other thing that comes to mind is icons, and I don't think they are all that applicable here.
