Hi..
I am working on a web application and storing logged in user to application object.
once they signout its entry will be deleted from application object - application["Loggedinusers"]
( I have stored arraylist as list of logged in users)
So , once the session ends by signout or timeout user gets deleted.
But it doesn't work when user closes the browser without logging out.
Means the entry is not deleted from Logged in users.
So next time if he logs in, " It says you are already logged in"....
Can you provide me the way to resolve this.
Thanks,

See, when user log out by signout or timeout then session_end get called so user gets deleted, but when user close the browser then session_end is called only when the time out expires. So when user tries just after closing the browser and try to open the application then it shows as logged in but if try to access after the session timeout then would not show because session_end will be called after timeout.
So if you want to logout just after the browser close then you have to detect the browser close and logout the user by code. So for this do the following
- Make an temporary page
- On pageload of this remove the user from applicaton object
- Now on every page of your application detect the browser close and load this page as popup with 0 size and after loading close this popup.
The code for detecting the browser close is like
function CheckBrowser()
{
if(window.event.clientX < 0 && window.event.clientY <0)
{
window.open("Temp.aspx",
"Operation",'left=12000,top=1200,width=10,height=1');
}
}
here Temp.aspx is your temporary page.
For details about Application Objects you han have a look to one of my article

As I am using master page.

I wouldn't use a window.open as that can be annoying and/or scary to users. I would probably use a XMLHttpRequest from the javascript since that is much less visible. Also another trick for pages that do not need to show the user anything and are just to update server-side info is set the http status code to 204.
Another option is to set a cookie when they close the browser. Whenever someone comes to your site check for the "ImReallyLoggedOut" cookie before showing the message.

Hello Every One,
i need an algorithm which i can use to retrieve controls from data base ordered ....
i have a function that loop through the page and get the id's of the controls on this page after that it goes to the database to insert this data .
The algorithm will help in retrieving these data ordered .
Example:
i have the following:
lbl_lable2-----txt_textbox1-----val_validator3
lbl_lable1-----txt_textbox3-----val_validator2
lbl_lable3-----txt_textbox2-----val_validator1
i loop through them and get all of them in the db ,Now i want to retrive from the db in this way:
lbl_lable1-----txt_textbox1-----val_validator1
lbl_lable2-----txt_textbox2-----val_validator2
lbl_lable3-----txt_textbox3-----val_validator3
Thanks in advance

Er, could you not bind the controls to, perhaps, the result of a DataTable or similar?

Hello all,
I'm working on some Desktop based Project in VB.Net in which I have made a page (say UpdateData.aspx) to update the employeeDetails.In that page, There is a DataGridView that displays all the detials. So, I'm using the cell_click event of the gridview. So, When I click on the gridview row, it retrieves all the records which are then populated into respective fields, except into 3 combobox fields.
I don't know what to do with them to enter some particular value into those comboboxes as those also contain some datasource.
And My code is like the following:
ds = obj.GetDetails(objBo)
If ds.Tables(0).Rows.Count>0 Then
comboItemName.SelectedText = ds.Tables(0).Rows(0)("itemName")
comboItemSerialNo.SelectedText = ds.Tables(0).Rows(0)("SerialNo")
END
please help...
Thanks in advance

I assume this was a typo.
Provided that you have setup the data source for the comboboxes in the template (if using them), and the selected text matches the valid entries, the display should be correct. You may also need to provide the selectedvalue properties though.
What is the error/problem?

Yeah, there are valid datasource in the combobox. The problem is that the value is not shown in the "comboItem" combobox for editing... in other words , combobox doesn't get value on edit...
what could be the error...

Please share the relevant code as the sequence of events might have some bearing on the problem.
Can you see the list of values in the dropdown?

Hi All i m creating the grid using the following way
<pre>
private void loadDynamicGrid(Int32 startTime, Int32 endTime, String firstTime)
{
//Create an instance of DataTable
//Create an ID column for adding to the Datatable
dt = new DataTable();
DataColumn dcol = new DataColumn(ID, typeof(System.Int32));
dcol.AutoIncrement = true;
dt.Columns.Add(dcol);
DataRow drow = null;
drow = dt.NewRow();
//Add the row to the datatable.
dt.Rows.Add(drow);
BoundField bfield = new BoundField();
if (String.Compare(firstTime, "firstTime") != 0)
{
GrdDynamic.Columns.Clear();
bfield.HeaderText = " " + "MODALITY" + " ";
bfield.HeaderStyle.BackColor = Color.LightGray;
bfield.HtmlEncode = false;
GrdDynamic.Columns.Add(bfield);
}
foreach (DataColumn col in dt.Columns)
{
for (Int32 index = startTime; index < endTime; index++)
{
Int32 hour = index;
for (Int32 minute = 0; minute <= 3; minute++)
{
//BoundField bfield = new BoundField();
bfield = new BoundField();
String headertext1 = ((hour.ToString()) + ":" + (15 * minute));
String[] headerText = headertext1.Split(':');
if (headerText[0].Length == 1)
{
bfield.HeaderText = " 0" + headerText[0] + ":" + headerText[1];
}
else
{
bfield.HeaderText = " " + headerText[0] + ":" + headerText[1];
}
if (headerText[1].Length == 1)
{
bfield.HeaderText = bfield.HeaderText + "0 ";
}
else
{
bfield.HeaderText = bfield.HeaderText + " ";
}
bfield.HtmlEncode = false;
GrdDynamic.Columns.Add(bfield);
//GrdDynamic.CellSpacing = 1;
}
}
}
//Initialize the DataSource
GrdDynamic.DataSource = dt;
//Bind the datatable with the GridView.
GrdDynamic.DataBind();

I have an xml configuration file in my project.
when I am working in debug mode of .net IDE it is working fine, but when i tried to launch the project from IE, it is taking different path
ex:
below code works well in debug mode, but unable to launch in IE directly (http://localhost/WebProj/login.aspx)
Pathtype A:
HttpContext.Current.Server.MapPath(@"\Configuration\xyz.xml");
below code works well in IE and debug mode but having different problem.
Pathtype B:
HttpContext.Current.Server.MapPath("") + @"\Configuration\xyz.xml";
Problem: I have a folder MainPages under root folder of the project. under this I have AdminPages. These admin pages are not retrieving if I used pathtype B specified above and gives error no page available, but works fine when pathtype A specified above is used which runs in debug mode only but not able launch from IE.
Help me please.

Hi KishoreT,
if i understand you right, you have the xml-file in a subdirectory of the root of the webpage. The subdirctory is "Configuration". Therefore i suggest you use the following to get the path:
HttpContext.Current.Server.MapPath(@"~\Configuration\xyz.xml");
The difference is the ~ (tilde) character. It represents the homedirectory or root of the webapp.
Hope this helps
Regards
Jens

Not an answer, but a question - Why are you creating the SP in your code?
Shreekar
|
|
|
|
|
Is the data the same in the two systems? Are you sure the query returns anything?
From the documentation for ExecuteScalar:
The first column of the first row in the result set, or a null reference (Nothing in Visual Basic) if the result set is empty.
You could try getting rid of the output parameter and just using a SELECT instead of a SET and RETURN.
Also, look into @ strings rather than lots of concatenation.
