A text file is an OK solution, if the website doesn't have a database behind it

1 - check if the file exists before you open it, if not create it
2 - use int.TryParse so that if the file is corrupt, it resets rather than blow up the site

You need some kind of locking. This is not thread safe.

Best method would be using services like Google analytics[^]. If you want to implement your own tracker, better use database to keep the information, you don't need to worry about thread safety. But keep it in mind, if the application is getting good hits, your database will become huge in size.

Globalization and Date Format

andrew_dk14-Apr-08 12:29

14-Apr-08 12:29

I have a function in an ASP.Net project that sets the date in a text box. ie

<br />
Private Sub SetDate()<br />
    Dim dateTimeFormatInfo As DateTimeFormatInfo = cultureInfo.CurrentCulture.DateTimeFormat<br />
    Dim dateStartDate As Date = Date.Now<br />
    txtStartDate.Text = dateStartDate.ToString("d", dateTimeFormatInfo)<br />
End Sub<br />

In my web.config I have:

<br />
<globalization requestEncoding="utf-8" responseEncoding="utf-8" uiCulture="en" culture="en-US" /><br />

When I run this locally I get the expected short date format, namely m/d/yyyy (on Windows XP SP2 using the VS web server). However when I run it on IIS on Windows 2003 the date is always formatted as dd/MM/yyyy. I thought this may have been something to do with regional settings on the server so I changed this. No difference. I tried uninstalling and reinstalling the .Net 2.0 framework but to no avail. When I do a:

<br />
Dim dateTimeFormatInfo As DateTimeFormatInfo = cultureInfo.CurrentCulture.DateTimeFormat<br />
Response.Write(dateTimeFormatInfo.ShortDatePattern)<br />

it is always output as dd/MM/yyyy. I know you can manually set the ShortDatePattern however I would prefer to know why this isn't working as expected. It's probably something incredibly trivial that I have overlooked. Any advice much appreciated.
Thanks.

Custom Control Problem

DominionZA14-Apr-08 11:14

14-Apr-08 11:14

Hi all,

I have created a custom web control that inherits from ListBox. My control has a property "LinkListBox" which is of type ListBox. When I dump my new control on a form, I can see the property, and when I select it, it lists all objects of type ListBox on the webform. 100% to now.
When I select a listbox from the dropdown however, I get the error
"Cannot create an object of type 'Savitar.Web.UI.WebControls.ListBox" from it's string representation 'ListBox1' for the 'LinkedListBox' property."

I have been googling for hours now to find a simple solution to this problem, and come across custom type converters etc... but just not managing to get anything to work.

My property looks as follows...

public ListBox LinkedListBox
{
get { return _LinkedListBox; }
set { _LinkedListBox = value; }
} ListBox _LinkedListBox = null;

Please would someone assist. Frustration is starting to kick in big time Smile | :)

Your issue is at design time, or run time ? Do people actually use the designer to create web forms ?

Michael Smit wrote:

This makes me think you need to support serialisation for your control.

The problem is at design time.

And ye... People definitely use the designer. We code in directly in the markup too, but only when necessary.

Simple but confusing ASP .NET /javascript question

Hi,

I have a webpage that has a remove button and everything works fine in it. But I want too add a simple(Are you sure[Yes, No]) alert to the button in the client side script for the button.

I searched in google but most things were about implementing client-side scripting for HTML server controls and I am a little bit confused on how to do a conditional postback for the page.

How can I implement a conditional Postback of the page using an alert?? Confused | :confused:

Thanks

If you add an OnClientCLick method to a button, the postback will only occur if the client side method returns true.

DataReader throws exception

Hi, I was wondering if anyone could help me with a DataTable problem. I am working in ASP.NET C#, The code that I have written is listed below. The moSqlDataReader can be viewed when in debug mode and the record that is asked for is seen, but when the reader is called into the DataTable using the .Load() function the DataReader shows a thrown exception of System.InvalidOperationException in the Depth and FieldCount properties when viewed in Debug mode

Code:

<br />
<small>msUserName = Request.QueryString.Get("username");<br />
            <br />
LabelUserName.Text = msUserName;<br />
UserName.Value = msUserName;<br />
moMembershipUser = Membership.GetUser(msUserName);<br />
<br />
msEmailAddress = moMembershipUser.Email;<br />
            <br />
moSqlConnection = new SqlConnection();<br />
moSqlConnection.ConnectionString = ConfigurationManager.ConnectionStrings["AppSqlServer"].ConnectionString;<br />
<br />
moSqlCommand = new SqlCommand();<br />
moSqlCommand.CommandText = "SELECT * From tblUserInfo WHERE UserID = @UserID ";<br />
moSqlCommand.CommandType = CommandType.Text;<br />
moSqlCommand.Connection = moSqlConnection;<br />
            <br />
// UserID Parameter<br />
moSqlParameterUser = new SqlParameter();<br />
moSqlParameterUser.ParameterName = "@UserID";<br />
moSqlParameterUser.SqlDbType = SqlDbType.UniqueIdentifier;<br />
moSqlParameterUser.Direction = ParameterDirection.Input;<br />
moSqlParameterUser.Value = new Guid(moMembershipUser.ProviderUserKey.ToString());<br />
            <br />
moSqlCommand.Parameters.Add(moSqlParameterUser);<br />
moSqlCommand.Connection.Open();<br />
<br />
moSqlDataReader = moSqlCommand.ExecuteReader(CommandBehavior.CloseConnection);<br />
<br />
moDataTable = new DataTable();<br />
moDataTable.Load(moSqlDataReader);<br />
<br />
if (moDataTable.Rows.Count == 0){<br />
      msFirstName = "";<br />
      msLastName = "";<br />
}else{<br />
      moDataTable.PrimaryKey = new DataColumn[] { moDataTable.Columns["UserID"] };<br />
      msFirstName = moDataTable.Rows.Find("FirstName");<br />
      msLastName = moDataTable.Rows.Find("LastName");<br />
}<br />
<br />
FirstName.Text = msFirstName;<br />
LastName.Text = msLastName;<br />
EmailAddress.Text = msEmailAddress;<br />
            <br />
moDataTable.Dispose();<br />
moSqlCommand.Dispose();<br />
moSqlConnection.Dispose();</small>

I dont understand why the application is returning this, I have checked the internet and several books but have found no reason for this error. I would appreciate if anyone could help fix this.

Thanks

Hi,

did you run a DEBUG over this part of code?
Can you place this code in a try...catch?

it will tell you where something goes wrong.

Hi, Thanks for replying.

Yes I have Debugged the code in order to find out what exactly is wrong but everything seems fine up until the DataTable uses the Load function again it displays the exception of System.InvalidOperationException in the Depth and FieldCount properties when in Debug mode.

I have not looked at trying the Try Catch methods yet. I will try these and see what l can find.

Thanks
