Store a list of session ids in the database. When a user logs in update the session ID in the database. After that, each time a user does something check that the session id they currently have matches the one in the database. If it doesn't match log them out. If it does match allow them to proceed.
Although it cannot imdiately log someone out (that is the nature of web applications). It does mean that the moment they try and do something they will be required to log in again.

You need to write some code. Sorry about that. You need to turn your list of emails into a collection of addresses which get applied to the to and the bcc, I guess.

Hi Christian,
First-of-all thanks for replying...
there is no issue to put the code and here is my code...
Dim Strsmtp As New System.Net.Mail.MailMessage
' MailFrom and MailTo come from the database
Dim from As New System.Net.Mail.MailAddress(objReader("MailFrom").ToString())
' Here i Put hard code emailids
Dim toList As New System.Net.Mail.MailAddress("abc1@abc.com;abc2@abc.com")
Strsmtp.From = from
Strsmtp.To.Add(toList)
Strsmtp.Subject = "Hi"
Strsmtp.IsBodyHtml = True
Strsmtp.Headers.Add("Content-Type", objReader("MailContentType"))
Strsmtp.Headers.Add("Reply-To", objReader("MailReplyTo"))
Strsmtp.Body = "Test"
Dim sp As New System.Net.Mail.SmtpClient()
sp.Send(Strsmtp)
and when i put the single emailid, then it gives different error that - Host Name is not specified.
But i already specified host name in my web.config file. Here is the code..
<system.net>
<mailSettings>
<smtp>
<network host="localhost" />
</smtp>
</mailSettings>
</system.net>
as i work in my local pc, so i write "localhost"...
Now i don't understand what i have to do???

The issue is that the object you call toList is not a list but a single object. You must add a separate MailAddress object for each address in your string.

I have a form with many controls and on several of the controls there is a on leave handler added. where each one connects to db and does validation and disconnects. is there a way i can connect to the db only once and then when submit is hit...disconnect. so i don't have many connect disconnects.
This is for ASP.net website form.

You should try using a dataset instead of making mutiple calls to the database. When you use a dataset, you'll make one query to your database and populate the dataset with that information. At which point you can bind that data to your controls. The link below is the msdn article for working with Datasets.
http://msdn.microsoft.com/en-us/library/system.data.dataset.aspx[^]
hope this helps

|

I can't use that because the reason i am making multiple calls is to validate the value in the text box control. So there are many controls that need validation..so on postback all this happens.
Is there any other way ... to keep a global db connection open for that page till submit is hit.

don't you think this error is self explanatory? check your input.

Well, as Yusuf said, the message is self explanatory. You have something that is a string (nvarchar) that you are treating as binary (varbinary) in SQL Server. SQL Server can't do that implicity. You have to be explicity and tell it how you want the information converted (or just confirm that you do really want it converted and it isn't an error in your code)
Since you've not shown the SQL code (this is a SQL Exception after all) we can't guide you into the portion that may be causing the error.

I have three ListBox on a page. Select a few items from ListBox1 and then click a button, the selected items are added to ListBox2 and ListBox3. Here is the interesting behavior I observed. See the code below. After the first loop, items are added to ListBox2. I de-select the added items in ListBox2 (ListBox2.SelectedIndex=-1). This statement not only de-select items in ListBox2 but also causes the loss of selections in ListBox1. As a result, the second loop does not add anything to ListBox3. If this statement is commented out, the second loop add all selected items from ListBox1 to ListBox3. Does anyone know why this is happening? Is this a designed behavior? How to workaround this? Thanks,
foreach(ListItem itm in ListBox1.Items)
{
if (itm.Selected)
{
ListBox2.Items.Add(itm);
}
}
ListBox2.SelectedIndex = -1; //This line makes difference
foreach (ListItem itm in ListBox1.Items)
{
if (itm.Selected)
{
ListBox3.Items.Add(itm);
}
}

hi..
Try out this..
foreach (ListItem itm in ListBox1.Items)
{
if (itm.Selected)
{
ListBox2.Items.Add(itm);
}
}
foreach (ListItem itm in ListBox1.Items)
{
if (itm.Selected)
{
ListBox3.Items.Add(itm);
}
}
ListBox2.SelectedIndex = -1;
And following will be the best option according to me:
foreach (ListItem itm in ListBox1.Items)
{
if (itm.Selected)
{
ListBox2.Items.Add(itm);
ListBox3.Items.Add(itm);
}
}
ListBox2.SelectedIndex = -1;
Thanks..

Thanks for your reply. Your solution definitely work. However, I placed one loop into a class to reuse it for all list controls like the following:
public void MoveListItem(ListControl Box1, ListControl Box2)
{
foreach (ListItem itm in Box1.Items)
{
if (itm.Selected)
{
Box2.Items.Add(itm);
}
}
Box2.SelectedIndex = -1;
}
I then call the method:
MoveListItem(ListBox1, ListBox2);
MoveListItem(ListBox1, ListBox3);
I guess the possible workaround could be to remove the de-selection statement Box2.SelectedIndex=-1 from the method and use it outside of the method:
MoveListItem(ListBox1, ListBox2);
ListBox2.SelectedIndex = -1;
MoveListItem(ListBox1, ListBox3);
ListBox3.SelectedIndex = -1;
Another possible way is to place ListItemCollection in the mehod to hold the selected items from Box1. After adding items to Box2, re-select the items in Box1. In this case, no de-selection is needed outside of the method call.
These are all workarounds. I still think the Box1 should not lose its selection when Box2 selection is cleared.
Thanks,

The issue was resolved. It is object reference that results in this behavior. When adding to ListBox2, create a new ListItem object to avoid the object reference between ListBox1 and ListBox1 like that following
ListBox2.Items.Add(new ListItem(itm.Text, itm.Value);
instead of
ListBox1.Items.Add(itm);

When I bring in a Report Viewer to my web form in crystal 11.5.37 it automatically adds references to 11.5.33 as well as 11.5.37 giving me duplicate references errors. If I delete the 11.5.33 references, it keeps recreating them when I build the web site. How can I permanently destroy them?

It turns out that Crystal 11.5 is not compatable with Visual Studio 2008. I need to update to Crystal 2008.

Not really related to Asp.Net.
I recommend you to repost your question in the appropriate forum to enhance the chance to get a proper answer.
But until then you can read up on Jagged Arrays here[^] or here[^] depending on your lingual taste.

put your dataset Table in to dataview and then
convert it back to table with distinct values and then covert datatable to array
as follow
C#
[code]
DataView dv=new DataView(ds.Tables["tblName"]);
DataTable temp=dv.ToTable(true,"col1","col2");
[/code]
now convert temp to array

Hi all,
i am kind new to ASP.NET, developing a asp.net web app with VS.NET2008 and C#.
I try to follow this tutorial:
http://www.fmsinc.com/FRee/NewTips/NET/NETtip35.asp[^]
, but it seems to be based on win32 code or something because on my web forms i cant find the same events, properties, etc. So i am traslating that code to the following:
Item = Row
grid_ItemCommand = grid_RowCommand
onmouseenter = onmouseover
onmouseleave = onmouseout, etc.
But still can't make it work on my GridView control.
Can anyone help me?
my code right now is:
protected void gvUsuarios_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Select")
{
gvUsuarios.SelectedIndex = ((GridViewRow)sender).RowIndex;
}
}
protected void gvUsuarios_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (gvUsuarios.SelectedIndex > -1)
{
GridViewRow gvr = ((System.Web.UI.WebControls.GridView)sender).Rows[gvUsuarios.SelectedIndex];
if (gvr.RowType == DataControlRowType.DataRow)
{
LinkButton button = (LinkButton)gvUsuarios.Rows[gvUsuarios.SelectedIndex].Cells[1].Controls[1];
if (button != null)
{
((GridView)sender).Attributes["ondblclick"] = ClientScript.GetPostBackClientHyperlink(button, "");
}
((GridViewRow)sender).Attributes.Add("onmouseover", "highlightRow(this, '" + ColorTranslator.ToHtml(gvUsuarios.SelectedRowStyle.BackColor) + "')");
((GridViewRow)sender).Attributes.Add("onmouseout", "dehighlightRow(this, '" + ColorTranslator.ToHtml(gvUsuarios.RowStyle.BackColor) + "')");
}
}
}
<pre>
Thanks a lot!
