Try HttpContext.Current.User.Identity.Name instead.

Hello Richard,
I already tried that.
It returns an empty string. 
Thanks,

That's because you've got anonymous access enabled. If you want to force everyone to authenticate, you'll need to replace <allow users ="*" /> with <deny users="?" />. You might also need to change the authentication settings in IIS.

Hello Richard,
I tried your above solution and modified authentication settings in IIS, I disabled Anonymous authentication and enabled windows authentication.
It allows only people with admin login to that server to login to the website and for the rest of the people within the same domain it gives error saying "Error 401: Not Acessible".
I am not sure, what is it that I am doing wrong here.
Please give me some advice.
Thanks,
Raesa

Go to IIS Set Anonymous authentication disable and windows authentication enable this will solve your problem.

Hello Mr.Shukla,
I had already done that.
It returns Error:401 and doesn't let me do anything.
Thanks,

You technically should not be able to get that information, if you do, then it's coming from the server that request was made on, and not the client machine.
Below is the correct response to the query, because it came off the web server.
raesark wrote: But it returns :
NT AUTHORITY\IUSR
If the query was made in a windows app running managed code on a client computer or server, then you would get the domain name and identity your looking for.
[edit]
You got the identity that made the request, which is anonymous or IIS_USR in IIS5 and IIS6
by design, Microsoft is closing the loopholes in asp.net when used for web applications, separating managed code functionality between windows apps and web apps. Someone should write and article on the subject.

Hello jkirkerx,
Thanks for the reply.
So, is there no way that I can get logged in username??
Please give me some advice.
I have done everything and it still returns me "
NT AUTHORITY\IUSR "
Thanks,
Raesa

Not that I'm aware of. If your running a vb, c# or c++ windows app you can, but on a web app, your going to get the IIS thread credentials that's running the web app.
If the web server app was programed to use windows authentication, and you login to the domain, you can probably get the current windows domain and user name.

I have a drop down list that is populated by reading the student's names that have less than 3 classes in a semester. It is also reading a class list that has a population of less than 10. I can get it to work if i ADD a NEW student and then that student has reached 3 classes it will remove his name from the drop down, and the same with the class when I click add it removes BOTH the student (if over 3) and the class (if more than 10). However .. Here is the problem. When I delete a student from the schedule it does not update the drop down list. I have several databinds() but it does not appear to fix things.
Ideally when it deletes a student from a class and let's say that student was formerly locked out (i.e. has 3 classes) - well then he has 2 and it should add his name if so to the drop down list (which is not updating). Thew same with CLASS since he dropped the class the count went down and if the class was full before it might not be now. Appreciate any insight you can offer. Weird how it works one way but not the other. In other words the grid is what is causing the problem - it updates but not the top part (drop down) even though I have databinds.
Here is the code:
using System;
using System.Data;
using System.Data.OleDb;
using System.Web.UI.WebControls;
public partial class frmRegisterStudent : System.Web.UI.Page
{
private void PopClass()
{
string path = Server.MapPath("eAcademy_DB.mdb");
string connectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + path;
string commandText10 = "SELECT class_ID FROM tblClass WHERE class_ID NOT IN (SELECT class_ID FROM tblschedule GROUP BY class_ID HAVING COUNT(class_ID) >= 10)";
var ds10 = new DataSet();
using (var connection10 = new OleDbConnection(connectionString))
using (var command = new OleDbCommand(commandText10, connection10))
{
command.Parameters.AddWithValue("@p0", ddlstudID.SelectedValue);
var adapter = new OleDbDataAdapter(command);
adapter.Fill(ds10);
}
ddlclassSelect.DataSource = ds10;
ddlclassSelect.DataTextField = "class_ID";
ddlclassSelect.DataValueField = "class_ID";
ddlclassSelect.DataBind();
ddlclassSelect.Items.Insert(0, new ListItem("Please Select", "0"));
}
private void PopStud()
{
string path = Server.MapPath("eAcademy_DB.mdb");
string connectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + path;
string commandText = "SELECT * FROM tblStudent where tblStudent.stud_id in (SELECT tblSchedule.stud_id FROM tblSchedule GROUP BY tblSchedule.stud_id HAVING count(tblSchedule.stud_ID) < 3)";
var ds9 = new DataSet();
using (var connection9 = new OleDbConnection(connectionString))
using (var command = new OleDbCommand(commandText, connection9))
{
command.Parameters.AddWithValue("@p0", ddlstudID.SelectedValue);
var adapter = new OleDbDataAdapter(command);
adapter.Fill(ds9);
}
ddlstudID.DataSource = ds9;
ddlstudID.DataTextField = "stud_ID";
ddlstudID.DataValueField = "stud_ID";
ddlstudID.DataBind();
ddlstudID.Items.Insert(0, new ListItem("Please Select", "0"));
}
private void CheckSession()
{
if (Session["SecurityLevel"] == null)
{
Response.Redirect("~/frmLogin.aspx");
}
}
protected void Page_Load(object sender, EventArgs e)
{
CheckSession();
if (!IsPostBack)
{
PopClass();
PopStud();
}
else
{
ddlstudID.DataBind();
ddlclassSelect.DataBind();
}
}
protected void AddClass_Click(object sender, EventArgs e)
{
if (ddlstudID.SelectedValue == "0")
{
lblErrStudentName.Text = "Please Select a Student.";
lblErrStudentName.Visible = true;
}
else
{
lblErrStudentName.Text = "";
lblErrStudentName.Visible = false;
}
if (ddlclassSelect.SelectedValue == "0")
{
lblErrClassSelect.Text = "Please Select a Class.";
lblErrClassSelect.Visible = true;
}
else
{
lblErrClassSelect.Text = "";
lblErrClassSelect.Visible = false;
}
if (lblErrStudentName.Text == "" && lblErrClassSelect.Text == "")
if (clsDataLayer.SaveSched(Server.MapPath("eAcademy_DB.mdb"),
(Convert.ToString(ddlstudID.SelectedValue)),
(Convert.ToString(ddlclassSelect.SelectedValue))))
{
txtVerifySaved.Text = "The information was saved.";
txtVerifySaved.Visible = true;
GridView1.DataBind();
PopClass();
PopStud();
ddlstudID.SelectedIndex = 0;
ddlclassSelect.SelectedIndex = 0;
}
else
{

}
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
PopStud();
PopClass();
ddlstudID.SelectedIndex = 0;
ddlclassSelect.SelectedIndex = 0;
}
}
ADDENDUM ; Going to try moving most of the code to the datalayer and see if it works better.

FIXED!
I hard coded the Delete Command to the Grid like this:
<asp:LinkButton runat="server"
CommandArgument='<%# Eval("class_ID")+ "&" + Eval("stud_ID") %>'
OnCommand="LinkButton_Click" Text="Delete">
</asp:LinkButton>
In the code back did this:
protected void LinkButton_Click(Object sender, CommandEventArgs e)
{
if (e.CommandArgument != null)
{
string MainString = e.CommandArgument.ToString();
string[] Split = MainString.Split(new Char[] { '&' });
Session["ClassID"] = (Convert.ToString(Split[0]));
Session["StudID"] = (Convert.ToString(Split[1]));
clsDataLayer.RemoveSchedule(Server.MapPath("eAcademy_DB.mdb"),(String)Session["StudID"],(String)Session["ClassID"]);
PopClass();
PopStud();
gvTeachers.DataBind();
Session["ClassID"] = null;
Session["StudID"] = null;
}
}
AND Lastly in my clsdatalayer:
public static void RemoveSchedule(String path, String StudX, String ClassX)
{
OleDbConnection dbConn = null;
OleDbCommand dbCmd;
OleDbDataReader dr;
String strConnection;
String strSQL;
{
strConnection = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + path;
dbConn = new OleDbConnection(strConnection);
dbConn.Open();
strSQL = "DELETE * FROM tblSchedule WHERE (class_ID=? and stud_ID=?)";
dbCmd = new OleDbCommand(strSQL, dbConn);
dbCmd.Parameters.Add(new OleDbParameter("class_ID", ClassX));
dbCmd.Parameters.Add(new OleDbParameter("stud_ID", StudX));
dr = dbCmd.ExecuteReader();
dr.Read();
dbConn.Close();
}
}
Now to just add back the TRY Catch and it should be working nicely.

I am running into a problem here, and I have no code needed or that requires debugging. I am looking for more of an idea to solve this issue, so here it is.
I have a *.exe that is a command prompt utility that generates images. What I am doing is using this utility for my asp.net website. In the background I do processing for each date in a asp.net calendar. If the image doesn't exist in the images directory for that date, Calendar_DayRender calls the backend to use the exe via Process. The image creation works great. As does the loading, if the image was already created in a previous session by any other user.
The problem is that the images are being created too quicky and I cannot load the image because when I try to add the Image to the cell, it was not created quickly enough. Any ideas on how I can solve this timing issue?
|
|
|
|
|
Check for the existence of the image file in the main thread before you send the reply to the client.
|
|
|
|
|
Make the image request synchronous? How are you requesting the image in the first place? If you do it with a tag, the browser should wait for a response.
I've done this in the past...
If the myImageGenerator.aspx page streams back an image, the browser will display it. I learned this technique from an OLD article on here about Captcha - the image streaming technique is still valid.
