Hi
I have used the following tutorial to create an autocomplete extender.
The problem is, it is not working. When I type text in the box nothing happens.
Is there something missing from the exampl code I have used.
I'm not sure where the string value gets filled which is shown in the tuturial.
Any help would be great
thanks!

I think problem is in webservice.I had case like you and when I added third line (of lines down below) it worked.
Try this:

[WebService(Namespace = "http://tempuri.org/")]<br />
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]<br />
[System.Web.Script.Services.ScriptService]

Thanks for the reply, but that didnt work.
Below is my code for extender control

<asp:textbox id="tb_description" runat="server" xmlns:asp="#unknown">
<atlas:autocompleteextender id="AutoCompleteExtender1" minimumprefixlength="1" runat="server" xmlns:atlas="#unknown">
<atlas:autocompleteproperties targetcontrolid="tb_description" servicemethod="GetactdescInfo" servicepath="~/autocomplete.asmx" enabled="True">

Is there anything wrong with that?

<asp:ScriptManager id="ScriptManager1" runat="server"><br />

OK, well there must be a problem with the web service then
The code is displayed below.When I type text in the box nothing appears
thanks

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class autocomplete : System.Web.Services.WebService {
[WebMethod(EnableSession = true)]
public string[] GetactdescInfo(string prefixText)
{

int count = 10;
string project = HttpContext.Current.Session["project"].ToString();
SqlConnection connectionString = new SqlConnection(ConfigurationManager.ConnectionStrings[project].ConnectionString);
connectionString.Open();
string sql = " SELECT description" +
" FROM act" +
" WHERE description like '" + prefixText + "' ";

//string description_condition = " AND description LIKE '%" + prefixText + "%'";
//sql += description_condition;

SqlDataAdapter dataAdapter1 = new SqlDataAdapter(sql, connectionString);
dataAdapter1.SelectCommand.Parameters.Add("@prefixText", SqlDbType.NVarChar, 2000).Value = prefixText + "%";
DataTable datatable1 = new DataTable();
dataAdapter1.Fill(datatable1);

string[] items = new string[datatable1.Rows.Count];
int i = 0;
foreach (DataRow datarow in datatable1.Rows)
{
items.SetValue(datarow["description"].ToString(), i);
i++;
}
return items;
}

Hi,

Is it possible to find the quality of the image?
How can we find the image is with good quality or not?

Not really an asp.net question is it.

This queston is ridiculous. How do you define 'quality'. ?

Actually while cropping the image, the image quality will get disturbed.
so,if that image quality is poor,then i need to display some error message.

Christian Graus10-Aug-08 22:45

Well, it's not possible. You can't quantify image quality, easily, in code. You could do a histogram and see how it spreads, if you like, and decide that reflects quality, but it's going to be hit and miss.
