Response.Write output control

hello,

i have 2 questions about output cache:

1.is it just me , or does it seems that it is used only after the second time that the user reaches the webpage? if so, why, and how can i tweak it to my needs? my guess is that it wouldn't be logical to cache every time a user reach a webpage, but only when it happens enough times.

2.i know that i can use "varybyparam" for using the output cache when the parameter doesn't change , but it seems that it would use the output cache even if there is no parameter , or if the specified paramter is not there. is there a way to overcome this?

3.an old question that somehow marked as "answered" , yet i didn't solve : suppose i created a user control and i gave it values through the CTOR via the aspx file . is it possible to show the values from within the split/design mode? remember that i've talking about ASP.NET and not simply C# winforms . i write this because this question was on :

http://forums.asp.net/t/1588671.aspx

and the answer that i got was for C# and winforms . i've tried to do the same for ASP.NET , but i've failed.

can anyone please help me?

I'm using JQuery and .NET ashx file (Generic Handler) to hand some  Web based input / output STUFF.
Works great.  My problem is, when I do view source in browser, I can clearly see the handler file for example
$.get('/MyApp/MyHandler.ashx'); How can I encrypt it so that it is not so obvious ?

Hi,

I have some code to stream files (for security of the files), the code works for all files in IE, and small files in firefox. but If the file is large (eg 750Mb) firefox hangs before it shows the open/save dialog box. 

However if i take out response.clearheaders and the response.flush in the code it does download but all the files downloaded by firefox are corrupt because the file size is too large.   Filenames are guids but I took the "-" out incase that was an issue.

If any one can shed some light on this I would be very grateful.

Function is Below. 

Private Sub StreamFile(ByRef response As HttpResponse, ByVal sFile As String)
            Dim fs As FileStream = Nothing
            Dim sFileName As String = Path.GetFileName(sFile)

            Dim oFile As New FileInfo(sFile)
            Try


                fs = New FileStream(sFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)

            Catch ex As Exception

                LogError(ex)
            End Try


        

             response.Clear()
            'response.ClearHeaders() 'makes file size wrong in firefox
            response.AddHeader("Content-Length", oFile.Length)

Hi all -

I've got a requirement to add a feature that will save off a dynamically created asp.net page so it can be recalled and reviewed at a later date. I was thinking of just adding a 'Save' button to the page and in the code-behind using VB to write the output HTML to a varchar(MAX) field in my database.

Does anyone know how (in VB) to grab the entire page HTML so it can be inserted into a database?

Thanks for any help!

I have a ListView (in an UpdatePanel) connected to a LinqDataSource. When the page loads and/or I navigate through Postback, the code snippet (below) will display the following output:

[email.gif] someone@adomain.com   [email.gif] www.adomain.com

However, when I use a few DropDownLists (also in the UpdatePanel) to filter the results (reset the DataSource to a Linq query and call DataBind), the same Contact is displayed like this:

[email.gif] [email.gif] www.adomain.com

<asp:ListView ID="lvEContacts" runat="server" DataSource='<%# Eval("Business_EContacts") %>'>
  <LayoutTemplate>
    <ul id="itemPlaceholderContainer" runat="server">
      <li id="itemPlaceholder" runat="server"></li>
    </ul>
  </LayoutTemplate>
  <ItemTemplate>
    <li style="display: inline; list-style-type: none;">
      <asp:Image ID="imgEContact" runat="server" ImageUrl="~/DesktopModules/images/email.gif" ImageAlign="Middle" />
      <%# FormatEContact( Eval("EContact.Address") ) %>

Hi all,

This is what I tried doing in my Javascript function (partially):

...
catch (err) {
              document.getElementById("lblError").innerHTML = err.description;
              //alert(err.description);
}

IE output of my lblError label component is a long id name like this:

...
<tr>
<td>Last Error: <span id="ctl00_ctl00_ContentPlaceHolder_GlobalMasterPage_ContentPlaceHolder_DashboardMasterPage_lblError">No errors at this time.</span>
</td>
</tr>                                                    
</table>

how do I look up for lblLabel in this case?

Thank you

I'm trying to pass a calculation from a response.write to a label.

    Public Sub StartTimeDif()
        Dim dt As DateTime = Convert.ToDateTime(starttimeInput.Text)
        Dim dt1 As DateTime = Convert.ToDateTime(endtimeInput.Text)
        Dim ts As TimeSpan = dt1.Subtract(dt)
        Response.Write(ts.Minutes)
    End Sub

I want to pass (ts.minutes) to durationLabel

Thank you,

Hello all,

Any suggestions are greatly appreciated...

Here is the website situation:

Webpage A: look & feel alignments are in the central of the screen.  It has a submit button.  The last code in the submit command() is this message subject:

Response.Write(string.Format("<script>window.open('{0}', '_blank');</script>", url));

where url = another webpage B.

The outcome is fine.  Webpage B is populated properly.  However, Webpage A postback as aligment to the left, it is no longer the center. 

I could not find a way to debug the issue.

Once again, thanks in advance.

Hello,

I keep getting this error:

CS0016: Could not write to output file 'c:\WINDOWS.0\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\42d038b5\b838d243\App_Web_master.master.cdcab7d2.lwqjolwv.dll' -- 'Access is denied. '

So, what I did is to set Full control to NETWORK_SERVICES user to both 'Framework\v2.0.50727\Temporary ASP.NET Files' and %temp% folder.

But still the error exist ....

What do I do next?

could it be a specific code I am trying to excute on the master page?

THANKS

Hi.
currently, I'm setting up an HttpCookie in a "master" page (layout) and check wiehter I need to send the user back to some specific page depending on the value, if it has expired, etc.
Because the master layout page is not the 1st "page" code to process, I can sometime get runtime error because the cookie is already expired.

I thought I would move this part to the _AppStart.cshtml file but I can't get to read/write (Response/Request) the cookie there?

Should I do this in a _PageStart.cshtml in all my folders rather?

Thanks

Hi All,

I have a unique project in mind which is based on a web browser, but requires that I perform some of the actions that the WebBrowser control does instead.

Basically, I want to be able to intercept/handle the web browser's requests and return data to the control which outputs the data to the clients screen.

For example:

1) A client requests a page.
2) My code handles this request and returns the HTML to the control.
3) The control then sends requests for each component which makes up the page (images, etc) and sends the requests to my handler.
4) My handler gets the data and returns it to the control.

Is there a way I can achieve this?

Thanks
Anubis.
