Hi all, I have the same question here. I am trying to build a chat application for my webpage. What i need to do have is implement private chat. So far i have done the chat application using a database and using a timer which checks every 3-5 secs to refresh the messages. My question is : I need to eliminate the use of timer and want to implement it as a condition. i.e only if the user enters a chat into the box should the other person refresh his text box and it shouldnt be run on a timer. Is it possible? Please help.

Here is the complete code listing. SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyCon"]); protected void txtdeptnos_TextChanged(object sender, EventArgs e) { plcHolder.Controls.Clear(); for (int i = 1; i <= Convert.ToInt32(txtdeptnos.Text); i++) { DropDownList ddl = new DropDownList(); ddl.ID = "ddl" + i.ToString(); ddl.AppendDataBoundItems = true; ddl.Items.Clear(); ddl.Items.Add("Select Department"); ddl.Width = 130; ddl.Items[0].Value = "0"; string strfac = "select deptid,deptname from department where bitDeletedFlag=0"; con.Open(); DataSet ds1 = new DataSet(); SqlDataAdapter da = new SqlDataAdapter(strfac, con); da.Fill(ds1, "department"); ddl.DataSource = ds1.Tables["department"]; ddl.DataTextField = "deptname"; ddl.DataValueField = "deptid"; ddl.DataBind(); con.Close(); plcHolder.Controls.Add(ddl); plcHolder.Controls.Add(new LiteralControl(" ")); plcHolder.Controls.Add(new LiteralControl(" ")); } } protected void BtnSave_Click(object sender, EventArgs e) { foreach (Control control in this.plcHolder.Controls) { if (control.GetType().Name == "DropDownList") { DropDownList dd = (DropDownList)control; depts = depts + ", " + dd.SelectedItem.ToString(); //I want to concartinate all the selected values of the drop downs and to be inserted into the DB at this click function. But the place holder gets empty. This loop is not executing totally. Session["val"] = dd.SelectedItem.ToString(); } } } Sagar Pattnayak Software Developer Sun-Dew Solutions +91-9831169962

Maybe you could start by taking a look at the soruce of TrueCrypt[^]. It is a open soruce program which lets you create virtual drives, which on the physical drives is an encrypted file. I hope that is something to start with :) //Johannes

Why dont you make user to upload the document and check if the earlier version exists?
