it could be path which when you deploy not recognised by app... or your DLL call another DLL method which is not there on deployment server.
sorry if its not the case.

I have a free website that allows alumni of my high school to sign up and share information. It's like classmates.com, except it's free to alumni of my school (http://www.daviehighalumni.com[^] if you're interested).
There is one user who likes to cause problems by posting offensive messages on my message board, annoy other users, etc. I can easily block this user from signing in, but have no restrictions on creating new accounts, so they can easily create a new account and continue their behaviour.
I could try requiring e-mail authentication before a new account can be used, but this person could impersonate another alumni who doesn't yet have an account. I can't base it on IP address because they change often. I can't base it on name or e-mail address because a person can easily use a different name or create a new e-mail address.
Here's my last attempt to block this person: I put a tag on their profile so that when they logged in, I set a cookie on their computer. From then on, if I see this cookie, I don't let them log on or create new accounts. I thought this would keep them out for sure, but it hasn't worked as they apparently know how to delete cookies or are going to different computers.
So, does anyone have any ideas on blocking a user from accessing a web site when the web site is free and allows users to create accounts?

you can set a message/post approve system which control by one or more site admins

Yeah, I was gonna say the same thing too. He can also create a dictionary of offensive words/phrases, and create a utility of some kind that checks user inputs against that list as a pre-approval process. Just a suggestion!

IMHO, one of the ways is to provide a link, say Report Abuse, so that other members of the site can use to report it to the admin board. Also, to gain more attention from the gurus here, you might consider posting this question in the lounge (as I don't think it's a programming question  ) where you can get a couple of golden tips from someone like the Lord Chris, code-frog, Andy Brummer ....

If your site is running on a Windows server, you could try parsing the output of...
nbtstat -A ipaddress

you can get value in ItemDataBound event and save it to string and use it in any function you want to use you can get value in ItemDataBound like this.
CheckBox cb = CType(e.Item.Cells(0).Controls(0), CheckBox); <br />
if(cb.Checked == true) <br />
string temp = e.Item.Cells(2).Text.ToString();

It looks like you are getting ALL the info for each row in the datagrid. This will overwrite string temp with the last row, which is the footer of the datagrid and therefore it will be blank.
You could test the checkbox in the forloop looking for the checkbox enabled
or / and
Have a string array and copy the cell information into the array
or
Use ItemDataBound on the row you wish to select to store the data.
Look where you want to go not where you don't want to crash.

How do you define the second column? Is it a bound column or a template column? Basically, you can use the Text property at a specific cell when the column is a bound column. If it is displayed via a control, you need to get reference to the control first, then get the value.

|
|
|

second column is template colummn in this i am binding like this
<ItemTemplate><br />
<%# DataBinder.Eval(Container.DataItem, "EMAIL")%><br />
</ItemTemplate>
plz tell e

Because you are using the data binding expression with the Template column, so the DataBoundLiteralControl is generated in each cell, and you need to cast the control in the Controls collection to this type before you access the Text property:
DataBoundLiteralControl lit = item.Cells[2].Controls[0] as DataBoundLiteralControl;
string value = lit.Text;

Hello All,
I'm trying to do a page which exports a table to Excel. But a set of statements gets printed on my page, when i try to export it again. The statements are:-
"Server: Microsoft-IIS/5.1 Date: Fri, 21 Jul 2006 11:32:11 GMT X-Powered-By: ASP.NET X-AspNet-Version: 1.1.4322 Content-Disposition: attachment; filename=FileName.xls Cache-Control: private Content-Type: application/octet-stream; charset=utf-8 Content-Length: 3908 "
At first i used "cache" instead of "viewstate".I thought cachewas making problems but all in vain.
Can anyone tell me what the problem is due to?
Thank you.
Regards,
Jeeva
My Code is:-
ViewState["DataTableExportToExcel"] = (DataTable)grdReportResult.DataSource;
private void ExportToExcel()
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
dt = (DataTable)ViewState["DataTableExportToExcel"];
ds.Tables.Add(dt.Copy());
clsGeneral objclsGeneral = new clsGeneral(); SaveExcel(objclsGeneral.SaveExcelToServer(ds,MapPath("Excell\\FileName.xls")));
//Procedure for exporting data to excel and save it into the server
//Cache.Remove("DataTableExportToExcel");
}
private void SaveExcelToClientMechine(string fileName)
{
System.IO.FileInfo targetFile = new System.IO.FileInfo(fileName);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + targetFile.Name);
Response.AddHeader("Content-Length", targetFile.Length.ToString()) ;
Response.ContentType = "application/octet-stream" ; Response.WriteFile(targetFile.FullName);
}
|
|
|
|
|
+ Using the ViewState to save the DataTable is not a good pratice as it's fit for the primitive stypes.
+ At the end of the SaveExcelToClientMechine method, you may try calling the Response.End method to avoid the html markup of the web page added to the output content.

Hi,
Thank You so much for the solution.
I was really worried with the HTML markup, when i gave Response.End() it came up all right.
Thanks a lot.

Try this
DateTime dt = DateTime.Now;
DateTime dt2 = DateTime.Parse("August 15, 2000 10:00:00");
TimeSpan ts = dt-dt2;
using ts object you will get everything.

Hi there.
I have a user control and a dynamically created dropdownlist on it. When I select an item in the ddl data is supposed to go into a textbox. The problem is that the SelectedIndexChanged event is only fired the second time I select some item in the ddl.
I think the problem has something to do with the viewstate - it's like the event isn't registered in the viewstate the first time I load the user control??
Here is my code which is in the Page_Load function in the user control:
DropDownList cboBUNK = new DropDownList();
cboBUNK.ID = "m_cboBUNK";
cboBUNK.CssClass = "controlText";
cboBUNK.AutoPostBack = true;
cboBUNK.SelectedIndexChanged += new EventHandler( onCboBUNKSelectedIndexChanged );
....
cboBUNK.DataSource = colBunkanr;
cboBUNK.DataTextField = "BUNK";
cboBUNK.DataValueField = "BUNK";
cboBUNK.DataBind();
cboBUNK.SelectedIndex = 0;
....
m_plhBUNK.Controls.Add( cboBUNK );

Do you add the user control to the web page dynamically or statically? Basically, the event gets fired based on the comparison of the current selected item persisted in the ViewState with the new posted value. IMO you may not need to set the SelectedIndex in the method. Also you may consider adding the dynamic control in the Page_Init other than the Page_Load.

Thanx 4 answering.
The user ctrl is added to the web page dynamically. I have 3 radio buttons on the page: Create, Edit and Delete.
> If the user chooses Create the placeholder in the user ctrl will contain a textbox control.
> If the user chooses Edit or Delete the placeholder in the user ctrl will contain a dropdownlist control with all the items he can change/delete. And it's that ddl that wont fire onSelectedIndexChanged event for the first time I pick something in it.
I commented out the set of the SelectedIndex and moved the code which adds the textbox/dropdownlist to the placeholder in the OnInit function but it made no difference 
Other suggestions?
P.S. IMO?
