Hi Mahdi Hokom,

Maybe you could try to use the following code to set the quality:

            Graphics g = this.CreateGraphics();
            Bitmap bm = new Bitmap(this.Height, this.Width);
            bm.SetResolution(g.DpiX, g.DpiY);//set Resolution
            Graphics grap = Graphics.FromImage(bm);
            grap.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;

Regards,

Moonlight

I think:

The bitmap you create when you do this.CreateGraphics() will be a copy of the window at the same dpi/resolution as the window on you rmonitor.

You've already lost data if you up the resolution afterwards.

You would need to draw the window at 600 dpi rather than 72 or 96 or whatever your window will be at.

The solution here redraws the window at the required resolution.

It's often better, in my experience, to offer a report rather than print windows if the user wants better than screen resolution.

Often, you don't want loads of stuff that goes in a window on a report and a4 is a different shape to most monitors.

Hope that helps.
