ASP.NET also has themes, but the HTML is already seperated from the code in ASP.NET, that's how it works. A well designed site, you should be able to restyle the ASPX files without having to touch the code behind.

You can define a header template, which means you can put controls in there, and thus subscribe to their events.

This is hard to understand. You should perhaps post some sample data to make sure we understand you. Are you asking how the UI should look, asking about the SQL, or what ?

Try to create a different application pool and change the Identity to Local System . Then asign the application pool to your site.

Flash, Handlers, and asp.net

Acorian12-Jun-09 5:32

I am currently working on a project that uses an ASP.NET handler that supplies the file path for a flash .SWF file which then gets played on the webpage. The handler uses an SQL database to get the file path information and I am using Querystrings to keep track of which video is being asked for. The Flash object simply uses the url to the asp.net handler instead of the url to the .swf file. This fires the handler and the actual flash .swf file is supplied and the video plays.

This is working just fine in Internet Explorer, but I am unable to get the file to load when using Firefox. Does anyone have any ideas or suggestions? Anyone ever had to use a handler in this way, or have any ideas on why Firefox 3.0 is not rendering the movie when IE 8 is?

I did this recently, and I found that I needed to render the path to the movie twice in order for it to work in Safari as well as in IE. I'm not sure I tested Firefox, it could work the same as Safari.

My control to play video looks like this:

<div style="vertical-align:middle;text-align:center;width:100%;height:100%">
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="<%=Width%>" height="<%=Height %>" id="player">
<param name="movie" value="<%=Player %>" />
<param name="FlashVars" value="videos=<%=URL %>&userKey=<%=UserKey %>&videoIndex=<%=VideoIndex%>" />
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always" />
<embed src="<%=Player%>" FlashVars="videos=<%=URL%>&userKey=<%=UserKey %>&videoIndex=<%=VideoIndex%>" width="<%=Width%>" height="<%=Height %>" name="player" allowfullscreen="true" allowscriptaccess="always" type="application/x-shockwave-flash" />
</object>
</div>

The important bit is the URL property, it's the path to the video, and notice I set it twice.

So long as you set the MIME type right, there's no reason on earth for your handler to not work with Firefox, it won't even be able to tell that there's a handler involved.

Thank you for the info. I compared what you posted with what I had and I did manage to get it working in FireFox after a bit of head scratching. For some reason the URL path was being rendered twice in the same attribute and giving me what basically amounted to a link within a link. I fixed that problem and now the flash vids are playing.

Thank you for the help!

showing progress in asp.net

Hi,
I have an asp.net page that need to show a progress bar. Progress bar is used to show progress of another windows service. The winservice writes its progress to a database table and based on that progress value i need to show progress bar in an asp.net page. I have made the page , but http being stateless shows only the first value. One way around would be to use a timer tick event. but i am not sure if thats a good solution.

Please provide with an idea on how to solve this problem or may be a good link would be good enough.
Thanx in advance.

I imagine some Ajax control can do this but it's still fundamentally the same thing. There is no getting around it because push does not exist so all you can do is pull-poll.

You are going to have to use some form of AJAX. You can use a timer to call one method at a certain interval to refresh the section of the page, or you can use some sort of counter in a loop inside your javascript. Either way you will be doing essentially the same thing.

Will setting static machineKey resolve FormsAuthentication issue in web farm??

Mark Graham12-Jun-09 5:09

Mark Graham

12-Jun-09 5:09

My site is hosted on a shared server that is load balanced in web farm. I don't have access to IIS, machine config files, or anything that isn't directly related to my FTP space and my Sql Server(and that's limited).

My Problem
I now want to introduce an authentication process in to the site. I already have my own 'CreateAccount' and 'SignIn' asp.net pages(not using Asp.Net provided controls), and I want to use them with FormsAuthentication class.

I want to know if adding static keys to machineKey section in MY SITE'S web.config (not machine web.configs) will resolve any potential issues with decrypted authentication cookies in web farm. I'm not familiar with the set up of farms but presumeably my site will be copied to several servers - all using the same web.config(my web.config)

Hope I've made myself clear. Please ask me a question if you aren't sure of anything...

Thanks for your time....

Cancel Postback of Textbox if it is blank

meeram39512-Jun-09 4:01

meeram395

12-Jun-09 4:01

I have a textbox in my form which is inside an updatepanel.
The functionality is, it checks whether the UserLogin is already exists in db.
If it's there, it shows error message, otherwise no. There is also a
requiredfield validator which shows that this field is required.
These are all working fine.

My issue is whenever the text box is blank, even though the requiredfieldvalidator
displays, it suddenly went off because of the postback of text box.
Following is my code. Could anybody please help where I'm doing wrong:

 <asp:UpdatePanel ID="UserNameUpdatePanel" runat="server" UpdateMode="Conditional
">
                                    <ContentTemplate>                                       
                                        <asp:TextBox ID="UserNameTextBox" 
AutoPostBack="true" OnTextChanged="UserName_Changed" runat="server" MaxLength="50"></asp:TextBox>               
                                        <asp:Label ID ="litusername" runat="server" 
Text="*" ForeColor="Red"></asp:Label>
                                        <asp:RequiredFieldValidator ID="UserNameRequiredFieldValidator" runat="server" ErrorMessage="Required Field" 
                                            Display="Dynamic" 
ControlToValidate="UserNameTextBox" CssClass="RequiredField">
</asp:RequiredFieldValidator>
                                        <asp:Image ID="UserNameImage" 
runat="server" Visible="false" />                    
                                        <asp:Label ID="lblMessage" 
runat="server" CssClass="ErrorMessagesLabel" ></asp:Label> 
                                        <asp:RegularExpressionValidator ID="UserNameExpressionValidator" runat="server" 
ControlToValidate="UserNameTextBox"
  CssClass="RequiredField" 
ValidationExpression="[\w|]*" ErrorMessage="UserLogin Already exists"></asp:RegularExpressionValidator>               
</ContentTemplate>               
</asp:UpdatePanel>

OnTextChange Event Handler:

protected void UserName_Changed(object sender, EventArgs e)
    {
        
    Business.User u = new User();
    lblMessage.Text = "";
    UserNameImage.ImageUrl = "";
    if (UserNameTextBox.Text != "")
    {
       string strUserName = UserNameTextBox.Text.Trim();
       List<string> UserNames = u.GetUserLogin();
       if (UserNameImage.Visible == false)
          UserNameImage.Visible = true;

        if (UserNames.Contains(strUserName))
        {
            UserNameImage.ImageUrl = "~/images/unacknowledged_x.gif";
            lblMessage.Text = "User Name Already Exists";
         }
         else
         {
           UserNameImage.ImageUrl = "~/images/acknowledged_checkmark.gif";
            lblMessage.Text = "";
         }
       }
       else
       {
          UserNameRequiredFieldValidator.Visible = true;
       }
        
    }

Not sure but I have an idea. Try something like this, no I didn't test it but it should give an idea of what you can do.

Try in C# in code behind in page_load

if (!ispostback)
{
UserNameTextBox.attributes.add("onChange", "script:if this.value == '' return false;");
}

ASP.NET is an attempt to put a stateful abstraction ontop of a stateless protocol. When you process a page in ASP.NET is only just got created. As soon as ASP.NET sends the page out to the client it is destroyed. When the client posts back a new page (that looks pretty similar to the last one) is created and you work on the new page. As soon as the processing of that is complete it is destroyed again.

Put simply. It does not and cannot work like a web forms application without significant additional server overhead - and that would place just too much strain on a server if it has to response to any more than a handful of users.

You have to think of ASP.NET applications differently to WinForms applications. They have different sets of constraints.

So, in order to help better we would need to know more about what you are attempting to achieve. What sort of workflow are you dealing with? Then we can advise how best to pass information around.
