Add New Point to Existing Point Shapefile To Inherit All Attributes

1

Hi, Jerry. Please take a moment off your busy schedule and look at this simple code. To Edit Shape Attributes, this code works fine. How can I create the same form with blank values based on existing Point Shapefile Attributes? So that I can just fill in the new values for the new Point on Save?

int layerHandle = axMap1.get_LayerHandle(0); // it’s assumed here that the layer we want to edit is the first 1 (with 0 index)
Shapefile sf = axMap1.get_Shapefile(layerHandle);
if (sf != null)
{
double projX = 0.0;
double projY = 0.0;
axMap1.PixelToProj(e.x, e.y, ref projX, ref projY);

        object result = null;
        Extents ext = new Extents();
        ext.SetBounds(projX, projY, 0.0, projX, projY, 0.0);

        // for polygon layers, tolerance can be left at zero
        double tolerance = 0;
        // but for point layers, we need to buffer the click point
        if (sf.ShapefileType2D == ShpfileType.SHP_POINT)
        {
            tolerance = 100; // meters
            Utils utils = new Utils();
            utils.ConvertDistance(tkUnitsOfMeasure.umMeters, tkUnitsOfMeasure.umDecimalDegrees, ref tolerance);
        }

        if (sf.SelectShapes(ext, tolerance, SelectMode.INTERSECTION, ref result))
        {
            int[] shapes = result as int[];
            if (shapes == null) return;
            if (shapes.Length > 1)
            {
                string s = "More than one shapes were selected. Shape indices:";
                for (int i = 0; i < shapes.Length; i++)
                    s += shapes[i] + Environment.NewLine;
                MessageBox.Show(s);
            }
            else
            {
                sf.SelectNone();
                sf.set_ShapeSelected(shapes[0], true); // selecting the shape we are about to edit
                axMap1.Redraw(); Application.DoEvents();

                Form form = new Form();
                for (int i = 0; i < sf.NumFields; i++)
                {
                    System.Windows.Forms.Label label = new System.Windows.Forms.Label();
                    label.Left = 15;
                    label.Top = i * 30 + 5;
                    label.Text = sf.Field[i].Name;
                    label.Width = 60;
                    form.Controls.Add(label);
                    TextBox box = new TextBox();
                    box.Left = 80;
                    box.Top = label.Top;
                    box.Width = 80;
                    box.Text = sf.CellValue[i, shapes[0]].ToString();
                    box.Name = sf.Field[i].Name;
                    form.Controls.Add(box);
                }
                form.Width = 180;
                form.Height = sf.NumFields * 30 + 70;
                Button btn = new Button
                {
                    Text = "Ok",
                    Top = sf.NumFields * 30 + 10,
                    Left = 20,
                    Width = 70,
                    Height = 25
                };
                btn.Click += BtnClick;
                form.Controls.Add(btn);
                btn = new Button
                {
                    Text = "Cancel",
                    Top = sf.NumFields * 30 + 10,
                    Left = 100,
                    Width = 70,
                    Height = 25
                };
                btn.Click += BtnClick;
                form.Controls.Add(btn);
                form.FormClosed += FormFormClosed;
                form.Text = "Shape: " + shapes[0];
                form.ShowInTaskbar = false;
                form.StartPosition = FormStartPosition.CenterParent;
                form.FormBorderStyle = FormBorderStyle.FixedDialog;
                form.MaximizeBox = false;
                form.MinimizeBox = false;
                form.ShowDialog(axMap1.Parent);
            }
        }
    }
    // Execute this code if you want to save the results.
    // sf.StopEditingShapes(true, true, null);

I tried several codes but nothing worked:
privateint _layerHandle = -1;

privatevoid StartEditing()
{
axMap1.GrabProjectionFromData = true;

string filename = @"d:\data\sf\buildings.shp";
var sf = new Shapefile();
if (!sf.Open(filename))
{
    MessageBox.Show("Failed to open: " + filename);
    return;
}

_layerHandle = axMap1.AddLayer(sf, true);

sf.InteractiveEditing = true;
axMap1.CursorMode = tkCursorMode.cmAddShape;  // cmEditShape, etc
axMap1.ChooseLayer += axMap1_ChooseLayer;

// doing some edits interactively

sf.StopEditingShapes();
}

privatevoid axMap1_ChooseLayer(object sender, AxMapWinGIS._DMapEvents_ChooseLayerEvent e)
{
if (axMap1.CursorMode == tkCursorMode.cmAddShape) // cmMoveShapes, etc
{
e.layerHandle = _layerHandle;
}
}

.
