Hi there,

well if you create an event in the form with the controls which passes a value of some sort (an enumeration based on the selected shape) and subscibe to that event in the form where you want to draw the shape, you can have a switch to based on the eventargs.

then its simply calling the right procedure to draw the right shape.

Good luck

dear knew that but how it is..
where can i call it. draw is a function and i have to take result in frmEditable (form) .can you say that i should call it on some controls?
if yes then how?
there is a huge confusion about this in my mind ..
kindly explain me with some code...
thx

first create the event:

event eventhandler<ToolTypeArgs> toolChanged;

when you raise the event:

if(this.toolChanged != null)
{
  this.toolChanged(this, new ToolTypeArgs(ToolTypes.Rectangle));
}

thats how to create an event with custom arguments, you need to first create the ToolTypeArgs class, it must inherit from EventArgs and I used a ToolTypes enumeration which you will need to create.

try this, subscribe to the event in the form where you will draw, use a switch in the eventHandler to call the correct draw procedure (or even better create overridden draw functions). Try this and if you still have problems, post the code with which you are struggling.

i m sending this..

namespace I_M_Editor
{
    public partial class frmMain : Form
    {
        Bitmap m = new Bitmap(2, 2);
        double Zoom = 1.0f;
      //  PictureBox pictureBox1=null;
 
            IDrawableImages img = null;
 //           IDrawableShapes shp= null; 
 
 
        public frmMain()
        {
            InitializeComponent();
            img = new Images();           
 
        }
 
        private void frmMain_Load(object sender, EventArgs e)
        {
            frmToolBox frm = new frmToolBox();
            frm.MdiParent = this;
            frm.Show();
            frmEditable frm2 = new frmEditable();
            frm2.MdiParent = this;
            frm2.Show();
 
 
        }
 
 
 
        protected override void OnPaint(PaintEventArgs e)
        {
 
 
        }
 
        private void tsxOptionOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
 
            openFileDialog.InitialDirectory = "c:\\";
            openFileDialog.Filter = "Bitmap files (*.bmp)|*.bmp|Jpeg files (*.jpg)|*.jpg|All valid files (*.bmp/*.jpg)|*.bmp/*.jpg";
            openFileDialog.FilterIndex = 2;
            openFileDialog.RestoreDirectory = true;
 
            if (DialogResult.OK == openFileDialog.ShowDialog())
            {
              m = (Bitmap)Bitmap.FromFile(openFileDialog.FileName);
        }
 
 
        }    
 
        public void Rect()
        {
            Graphics g = this.CreateGraphics();
            Pen p = new Pen(Color.Red);
            g.DrawRectangle(p, 260, 260, 100, 100);
 
        }
 
    }
}
 
 
 
namespace I_M_Editor
{
    public partial class frmEditable : Form
    {
        public frmEditable()
        {
            InitializeComponent();
 
        }
 
        private void frmEditable_Load(object sender, EventArgs e)
        {
 
        }
 
    }
}
 
 
namespace I_M_Editor
{
    public partial class frmToolBox : Form
    {
        public frmToolBox()
        {
            InitializeComponent();
        }
 
        private void lblRect_Click(object sender, EventArgs e)
        {
            ((frmMain)this.MdiParent).Rect();      
 
 
 
 
        }
 
 
    }
 

i want to draw it in frmEditable(form).
frmTools(form) contain tools from which i click lblRect (its a label)
,a rectangle should be drawn on frmEditable('s form).

ok, i gave a suggestion to use a custom event. I dont see you trying that anywhere, you dont use code tags and post REALLY quickly after i post. I take the time to think about your problem, please take the time to think about my post and try to use my advice or post 'no thank you' and i will stop. I'm not gonna write this project for you.

Best of luck to you

dear i m not asking you to write my whole project..
