Hi Guys,
I need your help  I have forms authentication setup on an asp.net portal. Even though I have the auth ticket to "NOT" persist, it does so after closing the browser... I have tried all the tricks with FormsAuthentication.SignOut() but still no cure.
Is there a way I could get rid of the forms auth cookie when the client browser is closed??
Many thanks in advance

How? That's the first thing I would check. If there is a mechanism that is supposed to result in the browser not caching the cookie and it's not working then the first thing I would suspect is my implementation of the mechanism.

Mike, I don't know what's causing it to behaive this way... I'm running out of options!
This is my code:
if (_IsAuthenticated)
{
FormsAuthenticationTicket _ticket = new FormsAuthenticationTicket(1,
this.userHandletbx.Text + "_" + DateTime.Now.ToString(),
DateTime.Now,
DateTime.Now.AddMinutes(30),
false,
String.Empty,
FormsAuthentication.FormsCookiePath);
string _encryptedTicket = FormsAuthentication.Encrypt(_ticket);
HttpCookie _authCookie = new HttpCookie(
FormsAuthentication.FormsCookieName,
_encryptedTicket);
_authCookie.Secure = false;
Response.Cookies.Add(_authCookie);
FormsAuthentication.RedirectFromLoginPage(this.userHandletbx.Text, true);
}
And this is my web.config:
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
name=".ASPXFORMSAUTH"
protection="All"
path="/"
timeout="40"
defaultUrl="Home.aspx"
enableCrossAppRedirects="false"
slidingExpiration="true">
</forms>
</authentication>
...and no matter where I stick
FormsAuthentication.SignOut() it doesn't kill that darn cookie!
Am I missing something? Is this a blonde moment I'm having? 
Thanks for your help, by the way.

Am I missing something?
First two obvious questions are:
1) Is the code executing? The function can't work if it is never being called.
2) Have you followed all the directions of the documentation for the SignOut method?

Hi,
I have a problem of storing .swf files to SQL Server 2005. Currently my application is storing Image( .bmp, .gif, .png, .jpg, .htm, .html,.png,wmf ) in Binary Field in a table.
I would like to store .swf file in the binary table and retrieve for further processing.
Appreciate if anybody has idea about this.
Thanks in advance.

If you are already storing ".bmp, .gif, .png, .jpg, .htm, .html,.png,wmf" then what is the difference between them and .swf?
|
|

|

I am getting OutofMemory Exception at below code -
newImage = Image.FromFile(value);
Reason: System.Drawing.Image doesn't support the .swf, so the problem is for uploading the flash.

A so nothing at all to do with "a problem of storing .swf files to SQL Server 2005" as you originally stated.
So, why do you want the swf file in the Image if you are just trying to upload it to the SQL Server? Is there something else you are doing with the file that you are not telling us?

I just want to store swf in SQL Server in binary field. The code snippet
Image newImage = Image.FromFile(Value) is Existing code and that causes the OutOf Memory Exception.
Just pl advice me as how to store .swf in binary field of SQL Server.
There is nothing that I am hiding from you. IT is just storing the .swf and display it in Winform and WebPage.
Thanks for your quick response.

It should be as you are doing just now. However, who ever wrote the code is attempting to load images into an Image object for some reason that seem unrelated to putting the image in the database.
How do you currently put the other image types in the database?

Hi all , again
I continue with my problem of export excel to sql-server.
I got export sheets of excel to a table of sql-server with this code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
'Path of file in machine of user
Label2.Text = System.IO.Path.GetFullPath(FileUpload1.PostedFile.FileName)
Dim connString As String = _
"Provider = Microsoft.Jet.OLEDB.4.0;" & _
"Data Source = " & "'" & Label2.Text & "';" & _
"Extended Properties = 'Excel 8.0;HDR=Yes'"
Dim cnn As New OleDbConnection(connString)
Try
Dim sql As String = _
"INSERT INTO T_Recibos " & _
"IN ''[ODBC;DRIVER={SQL Server};" & _
"Server=Ip_Server;" & _
"Database=NameDatabase;" & _
"UID=User;" & _
"PWD=password]" & _
"SELECT Id_Comunidad, Id_finca FROM [Hoja1$]"
Dim cmd As New OleDbCommand(sql, cnn)
cnn.Open()
Dim n As Integer = cmd.ExecuteNonQuery()
Label1.Text = "Número de registros afectados: " & n.ToString
Catch ex As OleDbException
Label1.Text = (ex.Errors(0).Message)
Catch ex As Exception
Label1.Text = (ex.Message)
Finally
' Cerramos la conexión
cnn.Close()
cnn = Nothing
End Try
End Sub
End Class
Now my problem is the next, when I try it from my web(not IIS local) and from Sql-Server allocated in my server (not my local Sql-Server) I receive a error that say me that doesn't find the excel file.
I understand why, the problem is that the path only work if the file excel is in the same server that SQL-Server.
A solve will be upload the file excel and later make all but I want to know if is possible with asp.net make it directly from file excel allocate in local machine of user to Sql-Server allocated in a server far of user.
Thanks again by all I am a little desespetare with this

Hi all,
I have a hyperlink in a Accordion ajax control,now i use this code for finding it:
Dim hpl As HyperLink = CType(acc.FindControl("hpl"), HyperLink)
this Error comes: object reference not set to an object
now how i can find my hyperlink  ?
Hoda
|
|
|
|
|
|
thank you,
1. Are you using tag for hyperlink or use HyperLink control from toolbox.
--->i used HyperLink control from toolbox.
2. If you are using control from toolbox, What is the ID of HyperLink Control.
--->I changed its ID to hpl.
Hoda
|
|
|
|
|
if you are using hyperlink control, why do you need to find that control. You can access it like:
Me.hpl.NavigateURL = "http://Yahoo.com"
be a part of the solution, rather then problem

I am a newbie at C#. Following code was generated mostly by the tool Visual Web Developer 2005 (with SQL Server 2008 express edition). It actually worked but now neither update nor delete work properly. There is no error message too. The database is very simple with a simple database table called 'Product'.
Any obvious gotchas - I have spent too much time on this already.
Thanks.

I'm trying to upload a file in VB.NET using an HtmlInputFile, but everytime I upload, the HtmlInputFile's PostedFile is Nothing.
Here is my ASP.NET code:
<form id="Form1" method="post" runat="server" enctype="multipart/form-data">
<asp:DataGrid id="dgTitles" runat="server" OnUpdateCommand="dgUpdate" DataKeyField="ID">
<Columns>
<asp:TemplateColumn HeaderText="Title" >
<ItemTemplate>
<asp:Label ID="lTitle" Runat="server">
<%# DataBinder.Eval(Container, "DataItem.Title" )%>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="tTitle" Runat="server" text='<%# DataBinder.Eval(Container, "DataItem.Title" )%>'>
</asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Image">
<EditItemTemplate>
<input id='fuEditImage' type="file" name="fuEditImage" runat="server" enctype="multipart/form-data" />
</EditItemTemplate>
</asp:TemplateColumn>
<asp:EditCommandColumn UpdateText="Update">
</asp:EditCommandColumn>
</Columns>
</asp:DataGrid>
</form>
Here is my VB.NET code:
Sub dgUpdate(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Try
Dim Title = CType(e.Item.FindControl("tTitle"), TextBox).Text
Dim fuUpload As System.Web.UI.HtmlControls.HtmlInputFile = CType(e.Item.FindControl("fuEditImage"), _
System.Web.UI.HtmlControls.HtmlInputFile)
If Not fuUpload.PostedFile Is Nothing Then 'This always = false
If Not fuUpload.PostedFile.FileName = "" Then
UploadImage(fuUpload)
End If
End If
Catch ex As Exception
'Handle Exception here
End Try
End Sub
When I upload a file, fuUpload is not Nothing, but fuUpload.PostedFile is.
The inputted "Title" text is recognized no problem.
I've also tried with FileUpload object and tag, instead of input tag and HtmlInputFile-- same result.
Can anyone tell me what I'm doing wrong? Why is PostedFile always nothing?
Thanks!
