C# - Transparency issues

[mcco]

I made a transparent titlebar for my program on photoshop, and saved it as png. Here is a screenshot of the bar(its on black background so you can see it):

Now, in VS(2008) I Set the form background to lime, and the transparency key to lime too. I add the titlebar I designed in as a custom control(it's background color is the bar), and it doesn't work.. I mean - I expected to see through the bar the actual screen, but i just see the Lime color under it.. it looks like this:

I tried to search for tutorials but i didnt find anything that could help me.
Please help me figure out the problem or point me to a tutorial.

Thanks in advance,

I think you need to set like "OwnerDraw" property and possibly draw your png to the graphics object itself?

hmm, maybe I just didn't get you, but it isnt working..
What I tried to do is drawing it on the form.. its still green..

I did it like this:

        
private void mainForm_Paint(object sender, PaintEventArgs e)         
{
             Point p = new Point(0, 0);
             e.Graphics.DrawImage(NewsPro.Properties.Resources.TransparentTitle, p);
}

Hmm, well once you create the image object inside your code, pick a pixel location that should contain that lime color and get the RGB value from it (GetPixel i thin kwill return the instance of a Color object which will work).
And then compare it to the lime color you picked as your transparency key and make sure they are identical.
They probably are, I just wanted to make sure it just wasn't some subtle differences between the two programs

Yeah, they are identical, and, I didn't get it, what to programs?
I still cant figure out how to do this..
I posted a question on MSDN but nobody answered yet..
