It might be you have used Forms Authentication in your application.
Put another Web.config file in your Images folder and remove the Authentication from that file.

Hi
Check the text is a valid url with regular expression, if valid then render the text with "<a href='textvalue'>textvalue</a>' tag.
Cheers

I am entering text in div on button click at runtime just like chat window when user click on send button the text is entered into div. In that case how to do this?
|
|
|
|

you will have to do the same thing that Prosanta already said...search for text that could be links and make them into links. Here is a sample that shows how to do this: http://benalman.com/code/test/js-linkify/[^]

Hi, you can refer to the following code:
private void Button1_Click(object sender, System.EventArgs e)
{
string strContent = InputTextBox.Text;// <---the input text
Regex urlregex = new Regex(@"(http:\/\/([\w.]+\/?)\S*)", // <--check if url
RegexOptions.IgnoreCase| RegexOptions.Compiled);
strContent = urlregex.Replace(strContent,
"<a href=\"\" target=\"_blank\"></a>"); // <-- set display like a link
Regex emailregex = new Regex(@"([a-zA-Z_0-9.-]+\@[a-zA-Z_0-9.-]+\.\w+)",
RegexOptions.IgnoreCase| RegexOptions.Compiled);
strContent = emailregex.Replace(strContent, "<a href=mailto:></a>");
lbContent.Text += "<br>"+strContent;
}

I am having the Aspx page in which button is there in update panel.when i click the button i have to display a message in messagebox.For that i am using class which is in seperate project.
public class Class1
{
//[DllImport("User32.dll")]
//public static extern int MessageBox(int h, String s, String s1, int type);
public void showmessage(Page sender,EventArgs e)
{
ScriptManager.RegisterClientScriptBlock(sender, sender.GetType(), "Key", "alert('Message Displayed');", true);
}
}
I am calling this class in my Web page.On button click i am calling this class methd which is showing the message box.Code for button click
protected void btnClick_Click1(object sender, EventArgs e)
{
TestClass.Class1 test = new TestClass.Class1();
test.showmessage(this.Page, e);
}
but it is not working.If i register the script on same web page then it is working fine or if i put button outside the updatepanel then it is working properly.
Is that any solution to register javascript on webpage through class? please reply..........

Hi
Try to use following code...
ScriptManager.RegisterClientScriptBlock(sender, sender.GetType(), "Key", "Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(function(){alert('Message Displayed');})", true);
Thanks

i read a article,
Person data access
public void Person_Save(ref int personID, string nameFirst, string nameLast, DateTime dob)
{
SqlCommand cmd;
ExecuteNonQuery(out cmd, "Person_Save",
CreateParameter("@PersonID", SqlDbType.Int, personID, ParameterDirection.InputOutput),
CreateParameter("@NameFirst", SqlDbType.NVarChar, nameFirst),
CreateParameter("@NameLast", SqlDbType.NVarChar, nameLast),
CreateParameter("@DOB", SqlDbType.DateTime, dob));
personID = (int)cmd.Parameters["@PersonID"].Value;
cmd.Dispose();
}
person Business
public void Save(IDbTransaction txn)
{
new Demo.DataAccessLayer.PersonDataService(txn).Person_Save(ref _personID, _nameFirst, _nameLast, _dob);
}
i implement in VB.net
Layer Access DATA
Public Sub contacto_cliente_auto_Insert(ByVal contacto_id As Integer, ByVal cliente_id As Integer, ByVal serie As String)
'revisado
ExecuteNonQuery(SP.Nombre.cw_co_contacto_cliente_auto.ToString(), _
CreateParameter("@i_contacto_id", AseDbType.Integer, contacto_id), _
CreateParameter("@i_cliente_id", AseDbType.Integer, cliente_id), _
CreateParameter("@i_serie", AseDbType.NVarChar, serie))
End Sub
Layer Business
Public Sub contacto_cliente_auto_Insert(ByVal contacto_id As Integer, ByVal cliente_id As Integer, ByVal serie As String)
new AccesoDatos.CRMWEB.AccesoDatos.contacto_cliente_autoCD().contacto_cliente_auto_Insert(contacto_id, cliente_id, serie)
End Sub
then new is incorrect in Layer Business.
i have the message Syntax Error
Thanks for the time
Regards

i think you should try the following
Dim a as new AccesoDatos.CRMWEB.AccesoDatos.contacto_cliente_autoCD
a.contacto_cliente_auto_Insert(contacto_id, cliente_id, serie) -Regards

I'm implementing 2 new sections into my current asp.net website: blogs & forums. These blogs & forums are both open source website projects that I downloaded, so as it stands right now, each one is its own separate website.
So I'm curious as to the best way to implement these 2 new sites into my current solution. My plan is to have their url setup as subdomains (i.e. http://blog.MySite.com, http://forum.MySite.com). Should I create 2 separate web projects within my solution (and if so, will I be able to pass session objects from one site to another)?
Just curious as to the best way to set this up to ensure the site still moves quickly and doesn't start allocating unnecessary resources (i.e. if I click on my forums, I shouldn't have to load blog data into memory).
Thanks.

Hi,
I was reading an ASP.NET reading about AJAX ScriptManager.EnablePartialRendering -
http://www.asp.net/learn/ajax/tutorial-01-cs.aspx
I have tried the example - it basically demonstrates Partial Rendering - without page refresh and render the whole page.
with ScriptManager.EnablePartialRendering = true, you click a button and change a text of a label. The text is updated by the script without posted back from the server evidenced by observing the rendered source page.
I copy exactly the same codes but everytime I click the button the page refreshes. I am using vs2005 .NET 2.0 and AJAX extension 1.0 (same version as used in the article)
I have examined after the page is loaded-
ScriptManager1.EnablePartialRendering = true
ScriptManager1.SupportsPartialRendering = true
Can anyone shed some light what might have gone wrong?

iam having the table log table
the fields are userid, logintime,logouttime,totaltimespend
when ever user login or logout he should be updated in database using triggers in sql server 2005 and using asp.net with c# and get the total hours he spend.
|
|
|
|
|
Totaltimespent is a useless column since you have logon and logout times.
I'm not sure I see your question
I know the language. I've read a book. - _Madmatt

As Mark said, you probably don't need the "totaltimespend" field. Keeping track of login & logout time should suffice.
I may be wrong on this, but triggers aren't the way to go for keeping a log table like this. Personally, I would update the "logintime" via my c# code when the user successfully logs in.
For logouttime, there's an event in your Global.asax file called "Session_End". Within there, simply open a connection to your log table and update logouttime.
Hope that helps.
