Bitmap.Save error

[Atli]

Hi.

Im trying to save an Image using C#, and I've created a code that, as far as I can see, should work.

Yet it keeps throwing a GDI+ generic Exception, without any usable error details. It doesn't matter what format I'm trying to save in, it always throws the exeption.

I'm using C# Express 2005 on Vista, if that matters.

Here is the code

using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Drawing2D;
...
private void SaveImage(object sender, EventArgs eArgs)
{
    Bitmap tmp = new Bitmap(200, 200);
    Graphics tmpG = Graphics.FromImage(tmp);

    tmpG.FillEllipse(Brushes.Black, new Rectangle(10, 10, 180, 180));
    tmpG.Save();

    tmp.Save("C:\\myimg.jpg", ImageFormat.Jpeg);
}

Any help would be great.
Thx.

Just found the problem.

Turns out I didn't have permission to write to C:\
Some security thing in Vista.
