Hello ,everybody, I'm a chinese,and my english is so bad.
I'm the beginner in VS2008.
I have a question about the masterpage.

When I build a new masterpage,a question appear.

The source code like this:

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage2.master.cs" Inherits="MasterPage2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <asp:ContentPlaceHolder id="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
        
        </asp:ContentPlaceHolder>
    </div>
    </form>
</body>
</html>

I don't do any change in the source code.

But the design view give me mistake like this:
//-----------------
Error Rendering Control - ContentPlaceHolder1

An unhandled exception has occurred.
This control can only be used in a MasterPage.

The above code does not give any error when I put your code in a master page in VS 2008.

Please check your extension of the above master page.

The above error could occure if you put the above code in an .aspx file.

Master pages should have the extension of .master.

Thank you.
But ,I checked my file's name,it is sure that the master page have the extension of .master.

Besides,I do a further checking.
When I remove the blank line in the "div" tags,the design view run normal.
Then I restored the blank line ,the page also gone well.

Next,I rebuild a master page again,the same as the last,design view report the mistake.
Then I remove the code <asp:ContentPlaceHolder id="head" runat="server"> </asp:ContentPlaceHolder> in the "head" tags,the master page also could run normal without mistake.
Like the last step,I restored the code in "head" tags,the master page run well.

I think,is there any bug with the VS2008 in my computer?

Because I also meet a similar problem about the master page in another project. The mster page run very well,but the other .aspx pages which use the master page,have nothing in design view.

All the above-mentioned pages can run very well in Browser.
And the Wrong master pages also can view normally with no mistakes in VS2005.

HELP - Forms Auth Cookie persists after closing browser...

Hi Guys,

I need your help Smile | :)

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 Smile | :)

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, // Value of IsPersistent property
                    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? Poke tongue | ;-P

Thanks for your help, by the way.

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?

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. Smile | :)

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?

Export a sheet of excel to a table Sql-Server

Hi all , again Smile | :)

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 Confused | :confused:
