Your problem is with the following line and is what I suspected:

Options myoptions = new SampleOptions();

The myoptions variable is of type Options, not SampleOptions. Eventhough, the actual instance is a SampleOptions, since the variables type is Options it cannot see the file field (which is defined in SampleOptions).

If you update your code to be:

SampleOptions myoptions = new SampleOptions();

Then myoptions will be of type SampleOptions and will be able to see any fields defined in it.

Take care,
Tom

thanks, i havent checked the datagridview. i might do that later

another question regarding the tables
i choose the View to details and set some test rows. when i run the program and click on each row, the entire row wont get selected. if i click on the first column only that row and column will get selected. is there a way to get the entire row selected?

its not an important thing. but i think its neater than the current one

Hi,

forget the PictureBox; replace it by a regular Panel plus some code:
- some initialization to load the picture
- a Paint handler to paint the relevant part of the Image in the Panel, using one
of the many overloads of Graphics.DrawImage().

By adjusting the source rectangle (one of the parameters in DrawImage) you can get any
pan&zoom you want; to update the display, you should adjust the parameters and call
Panel.Invalidate().

You will have to develop your own property to set the effects that you would like. Then you will need to override the OnPaintBackground method.

<br />
protected override void OnPaintBackground(PaintEventArgs e)<br />
{<br />
// Custom paint code<br />
}<br />

Import a colour?

I'm not sure what you mean, but there's a couple of ways you can get a colour:

1: By Name

Color myColour = Color.DarkGreen;

2: Specify the RGB values

Color myColour = Color.FromRGB(50, 255, 200);

My current favourite word is: Waffle

Cheese is still good though.

Though not stripes, I threw this example together. You can paint anything in OnPaintBackground.

<br />
        Color m_Color1 = Color.Red, m_Color2 = Color.Black;<br />
<br />
        public Color Color1<br />
        {<br />
            get { return m_Color1; }<br />
            set { m_Color1 = value; }<br />
        }<br />
<br />
        public Color Color2<br />
        {<br />
            get { return m_Color2; }<br />
            set { m_Color2 = value; }<br />
        }<br />
<br />
        protected override void OnPaintBackground(PaintEventArgs e)<br />
        {<br />
            Brush brush = new System.Drawing.Drawing2D.LinearGradientBrush(new Point(e.ClipRectangle.Left, e.ClipRectangle.Top), new Point(e.ClipRectangle.Right, e.ClipRectangle.Bottom), m_Color1, m_Color2);<br />
            e.Graphics.FillRectangle(brush, e.ClipRectangle);<br />
        }<br />

Well, you could remove the tab page when its useless, and add it back again when it becomes usefull. I'm pretty sure each tab page is a whole separate object.

My current favourite word is: Waffle

Cheese is still good though.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
