using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace TestComboBox

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

}

//Form uses a Combo Box to select different shapes to draw and fill (using Graphics, Pen and Solid Brush object;

private void ComboBoxForImage_SelectedIndexChanged(object sender, EventArgs e)

{

//create graphics object,Pen,SolidBrush..........................

Graphics myGraphics = base.CreateGraphics();

//create Pen using Color DrakBlue...............................

Pen myPen = new Pen(Color.DarkBlue);

//create SolidBrush using Color DrakRed...............................

SolidBrush mysolidbrush = new SolidBrush(Color.DarkRed);

//clear drawing area,setting it to color white..................

myGraphics.Clear(Color.White);

//get index of selected ComboBox for Draw Shape and Fill Shape

switch (ComboBoxForImage.SelectedIndex)

{

case 0:

//case 0: for draw Line...........(myPen,int x1-axis,int y1-axis,x2-axis,int y2-axis)

myGraphics.DrawLine(myPen, 50, 100, 200, 345);

break;

//case 1: for draw Circle...........(myPen,X-axis,Y-axis,width,height)

case 1:

myGraphics.DrawEllipse(myPen, 100, 100, 150, 150);

break;

//case 2 for draw Rectangle with height and width are different...........

case 2:

//case 3 for draw Square with height and width are same...........

case 3:

break;

//case 4 for draw Ellipse with height and width are different...........

case 4:

break;

//case 5 for draw Pie...........(myPen,X-axis,Y-axis,width,height,start angle,sweep angle)

case 5:

break;

case 6:

break;

case 9:

break;

case 10:

myGraphics.FillPie(mysolidbrush, 50, 50, 150, 150, 0, 45);

break;

}

// release the Graphice object...................

myGraphics.Dispose();

}

}
