Hi, You can use the HashSet as: Hashset(Key(Type1), Value (List(Type2)))

Dictionary> dicElements;

Hi all, I found an article contains an other solution: Zeta HTML Edit Control[^] enjoy :)

Hi, You can implement the cell paint event. I think that you have a data table like this: (Val1, Val2, PicturePath, ...). You can find bellow an example of code that shows in a data grid view a grid contact: ---------------------------------------------------------------- |Picture | First Name | Last Name | Phone number | ---------------------------------------------------------------- |    ;)   |     Mr. X       |   X1            |  00112233       | ---------------------------------------------------------------- |    ;)   |     Mr. X       |   X1            |  00112233       | ----------------------------------------------------------------

// Subscribe to the event cell painting
myDataGridView += new DataGridViewCellPaintingEventHandler(myDataGridView_CellPainting);

// Implement the event
void myDataGridView_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
// Test if you are drawing the picture cell. Note that the RowIndex == 0 is the row header
if (e.RowIndex > 0 && e.ColumnIndex == 0)
{
try
{
string strPath = myDataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
// To optimize you program, you can store the loadeds picture in a dictionary like this:
Bitmap objPicture = null;
if(dicPictures.ContainsKey(strPath))
{
objPicture = dicPictures[strPath];
}
else
{
objPicture = Bitmap.FromFile(strPath);
dicPictures.Add(strPath, objPicture);
}

         e.Graphics.DrawImage(objPicture, e.CellBounds);
       }
       catch (Exception Error)
       { 
          // Error Log or Managing
       } 
   }

}

Hi, To start writing mail, the correct instruction is:

Process.Start("mailto:name@company.com");

then you must change you code as:

Process.Start("mailto:" + this.dgvPresenters[e.ColumnIndex,e.RowIndex].Value.ToString());

Hi, My idea is converting an RTF document to HTML because the rich text control offers the RTF output result. 1)You can use this article to create an advanced rich text box: RicherTextBox 2)To convert the RTF result, you can use the

"SautinSoft.RtfToHtml"

. For the trial version you can convert over 30000 words :^)

private string GetHtmlText(string strRtfText)
{
if (string.IsNullOrEmpty(strRtfText)) return "";

        string result = "";

        #region Version SautinSoft

        SautinSoft.RtfToHtml r = new SautinSoft.RtfToHtml();
        //this property is necessary only for registered version
        //r.Serial = "XXXXXXXXXXXXX";

        //specify some options
        r.OutputFormat = SautinSoft.RtfToHtml.eOutputFormat.HTML\_5;// SautinSoft.eOutputFormat.XHTML\_10;
        r.Encoding = SautinSoft.RtfToHtml.eEncoding.UTF\_8;// SautinSoft.eEncoding.UTF\_8;

        //specify image options
        r.ImageStyle.ImageFolder = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\\\TempFiles";      //this folder must exist
        r.ImageStyle.ImageSubFolder = "webs";   //this folder will be created by the component
        r.ImageStyle.ImageFileName = "picture"; //template name for images
        r.ImageStyle.IncludeImageInHtml = true;//false - save images on HDD, true - save images inside HTML


        result = r.ConvertString(strRtfText);

        #endregion

        return result;
    }

Hi

Dan_K

, To draw object under any control, you must implement the event "OnPaint". You can use this code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

        panel.Paint += new PaintEventHandler(panel\_Paint);
    }

    private void void panel\_Paint(object sender, PaintEventArgs e)
    {
                         

        e.Graphics.DrawString("Problem drawing text on Panel", panel.Font, Brushes.Black, 50, 50);

    }
}

}
