Hi
I am having some problem while I try to retrieve an email address from the active directory

The scenario is that
I am having a login name and with that I want to get corresponding email address from active directory.

Then I have to send an email to the email address through code..
--------------------------------------------------
while directory search it is giving me an exception
DirectoryEntry objDEntry = new DirectoryEntry("LDAP://domain/DC=domain,DC=co,DC=in");
DirectorySearcher objDSearch = new DirectorySearcher(objDEntry);
string username = Session ["Name"].ToString ();
MsgBox3.alert(username);
objDSearch.Filter="(&(objectClass=user)(l=" + username + "))";
//string email;
//SearchResult sResultSet=null;
objDSearch.PropertiesToLoad.Add("cn");
MailMessage objEmail = new MailMessage();
MsgBox3.alert("good");
SearchResult sResultSet=objDSearch.FindOne(); [here is where the exception comes]
-------
System.Runtime.InteropServices.COMException (0x80072020): An operations error occurred at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at System.DirectoryServices.DirectorySearcher.FindOne()
----------

Kindly help me out regarding this

Does the ASPNET worker process have the appropriate permissions to access the directory?

Using Querystring
Querystring is a day old mechanism to pass values across pages. The main advantage of this method is it is very simple. However, disadvantages are the values are visible in the browser address bar and you can not pass objects this way. This method is best suited when you want to pass small number of values that need not be secured from others. In order to implement this method you will follow these steps:
§ Create the web form with controls
§ Provide some button or link button that posts the form back
§ In the click event of the button create a string that holds URL for another
§ Add control values to this URL as querystring parameters
§ Response.Redirect to another form with this URL
Following code snippet shows how it works:
Source Web Form
private void Button1_Click
(object sender, System.EventArgs e)
{
string url;
url="anotherwebform.aspx?name=" +
TextBox1.Text + "&email=" +
TextBox2.Text;
Response.Redirect(url);
}
Destination Web Form
private void Page_Load
(object sender, System.EventArgs e)
{
Label1.Text=Request.QueryString["name"];
Label2.Text=Request.QueryString["email"];
}

Server.Transfer
This is yet another way to pass values across pages. Here you store control values in session variables and access them in another web form. However, as you know storing too much data in session can be an overhead on the server. So, you should use this method with care. Also, it requires some kind of clean up action from your side so that unwanted session variables are removed. The typical sequence of steps will be as follows:
§ Create the web form with controls
§ Provide some button or link button that posts the form back
§ In the click event of the button add session variables and set them to control values
§ Response.Redirect to another form
§ In that form access Session variables and remove them if necessary
Following code shows this in action:
Source Web Form
private void Button1_Click
(object sender, System.EventArgs e)
{
//textbox1 and textbox2 are webform
//controls
Session["name"]=TextBox1.Text;
Session["email"]=TextBox2.Text;
Server.Transfer("anotherwebform.aspx");
}
Destination Web Form
private void Page_Load
(object sender, System.EventArgs e)
{
Label1.Text=Session["name"].ToString();
Label2.Text=Session["email"].ToString();
Session.Remove("name");
Session.Remove("email");
}

Can we bind datareader to textboxes?

I found out we could bind datareader to grid, dropdown list etc. but can we bind datareader to textboxes? if it is possible how to do it?

hi,
yes you can bind textboxes to a datareader. A textbox can be bounded with one record of a datareader object like that.....

//make connection,command object then....<br />
        Connection.Open();<br />
        reader=SqlCommand.ExecuteReader();<br />
        reader.Read();<br />
        TextBox1.Text =reader.GetString(1);

i dont think so you can bind to textbox. you can set the value from reader to textbox.

hi nav,
yes you are partially right. actually the problem arises when the datareader has null values.Isnt it? Other wise do u think that the following code is incorrect.
txtName.text=reader("Name")

whats ur opinion?

completley agree with you its ok if we not getting any null values. and we can set a check for null as wel. but if we look at the question its not binding its jus a way to getting and setting a value to textbox.

I want to use DataViewManager to bind data to a datagrid in Asp.Net. How is this possible?

Re: How can we use DataViewManager to bind data to a datagrid in asp.net?

5-Jul-06 22:35

first create a datatable

DataTable dt = new DataTable("TestDT");<br />
        dt.Columns.Add("ID");<br />
        dt.Columns.Add("NAME");<br />
        for(int n=1; n<3; n++)<br />
        {<br />
          DataRow dr = dt.NewRow();<br />
          dr["ID"] = n.ToString();<br />
          dr["NAME"] = n.ToString() + n.ToString();<br />
          dt.Rows.Add(dr);<br />
        }

then add datatable to Dataset

DataSet ds = new DataSet("TestDS");<br />
ds.Tables.Add(dt);

Create dataviewmanager
DataViewManager dvm = new DataViewManager(ds);
bind it to datagrid
dataGrid1.DataSource = dvm;

and finish
