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.

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

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

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.

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?? 
Thanks
And ever has it been that love knows not its own depth until the hour of separation

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

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 />
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

Got the Error:
You us e a DataReader object instead of a DataTable object.
The reader will give up data per row until there is no more to give.
After loading a datareader you ask 2 things
if (moSqlDataReader.HasRows)
{
WHILE (moSqlDataReader.Read())
{
// your code here
}
}
in your case it is better to do a
DataSet dSet = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter("Query", con);
adapter.SelectCommand.CommandType = CommandType.Text;
etc ..
adapter.Fill(dSet);

Double check your query is correct and maybe try another simple query and load that
this will eliminate the possibility that it is your query which is the problem
or it will highlight what the problem is
|

|
|
Have you declared moSqlDataReader ?

anybody knows a complete article about "Membership and Role Management" in asp .net 2 or 3.5 for “MS SQL Server”?
an article that describes the whole process completely?
i already searched for it but they were confusing!
thank you

Hi..
im using session variables to store the login information of the user..
When user login and logout he cant review the pages he visited, its working fine ...
but if another user login's he can see all the pages visited by the previous user by clicking back button. Since session ID is not null it allows the page to appear..
Can u tell me how to remove all browser list on Logout..
thanks in advance
|
|
|
|

I dont think you can delete the browser history, you can delete sessions when you logout, is this what you mean?
