I've always wanted a skinning framework for .NET.  Lately I've been getting good with custom drawing tasks, and I wanted to dive a little more into windows messages and that, and decided to take a crack at it.  After a start in the right direction but some confusion, I stumbled across a blog entry that laid it out.  After getting it working fairly well on the first run, I scrapped what I had and rewrote from the ground up.

Above is a fairly full-featured skin designer program (it doesn't have Save, but it wouldn't be hard to do).  All of the classes related to adding skin elements are marked Serializable, so pretty much all you need to do is make a call to the BinaryFormatter class.

There are two rendering base classes -- SkinElement and MultiStateSkinElement.  They provide interfaces which any custom designer should implement.  For example, there is an implementation of SkinElement called VectorSkinElement -- it allows you to define a GraphicsPath with any number of points with a given pen and brush.

I'm having some problems with some things:
* For whatever reason, when I press and hold a caption-bar button, it doesn't go into its "Pressed" state.  Furthermore, if I move the mouse while I've got it down, it draws the Windows-equivalent button.  Eww!
* Even more confounding is that the above behavior only happens in the debug version -- in the release version, when I roll the mouse off of the button it minimizes/maximizes/closes.
* The transparency key property shouldn't be used like I did (to make the transparent color part of the skin do its thing) -- I want to find another way to allow rounded edges and such.

Things I want to do with this still
This represents a week's worth of time at work (48 hours this week).  It's still in its infancy.
* I want to be able to provide custom painting for any controls that are on the form.
* I want to make a Brush designer, so that (for example) the Title text, since Graphics.DrawString takes a Brush parameter, could be painted with a LinearGradientBrush.
* I need to implement the basic SkinElement designer window, which means I need to implement extensibility.  The idea is that you could tack-on other .NET assemblies and use them as additional skin element renderers.  The form that pops up when you click the "..." button in the skin designer is supposed to let you do that.
* I want to create a custom-drawn Menu framework (flat Office 2003-like menus) and provide a way for that to be integrated.

I'll be adding several properties and methods over the time ahead when I get to play with this, so don't expect me to worry about compatibility until I make an "official" release.  The code I've posted is free to be used in whatever non-commercial means you wish, as will be true of any future releases I make.  I also am welcome to any comments/criticisms you might have.

Code/binaries:

If I used .NET, I'd have used that :-/

Ooops, I fixed the link to the code/binaries.

I have updated this.

Web documentation: here (note that this is severely incomplete)
Binary/code/HTML Help: here

I have fixed transparency so that the transparent parts are on a per-skin-element basis.
I have made a brush designer, but need to add Path- and LinearGradient brushes to it.
I need to make a Path designer, or find one online.
Button "pressed states" are fixed.
I still need to make a SkinElement designer window.
Better design-time support.
I added the ability to make the form have a drop-shadow in Windows XP by overriding the DropShadow property in the derived form and returning true.  This is *NOT* a design- or run-time property.
I updated the skin designer to support saving/opening and preview.

I would greatly appreciate any assistance you guys could offer in terms of testing and finding runtime bugs.  Please post anything you find here.

Myndfyre, I don't know how you do it man.
Good job.

Very nice.

This is updated.  Same links as above -- code/binaries and documentation online.  Only a few changes:
-- Fixed the button weirdness on the caption bar.
-- Documented a FEW (notably FEW) things
-- Added support for ISerializable on MSImageSkinElement
-- Added a DEBUG build tool that you can use to watch stack traces.
-- I think that's it.
