I understand how to use App_Offline.htm, and most of its caveats, but what I can't seem to find information on is how it deals with executing threads. What I'm concerned about specifically is this. Our company website allows our users to post online payments for their bill with us. Lets say we go to do production maintenance at night, and drop in App_Offline.htm. But we have 3 users submitting payments at that exact moment. I know that App_Offline.htm will block any further responses from coming from ASP.NET, but does it abort the web services calls, or does it allow them to finish, and only then tear down the sessions?
Thanks in advance.

If the file exists, then ASP.NET shuts down the application and sends the contents of the file back to the user's browser for any new requests to dynamic pages in the application.So in your case the server side code for payment process wont execute, because users are basically locked out of the application.

Hope this will help.

Thanks for the reply, Shahriar. But I was referring more to what happens to any active Web Service calls being made. Let me try to explain it a different way. Let's say the payment process takes 30 seconds to return from a 3rd party vendor (they own the Web Service, we're just calling in to it). 10 seconds in to a call, we drop in App_Offline.htm, and shut the site down. Does the payment process Web Service call to our 3rd party vendor complete? Or is it aborted by the shutdown of our application. Either way, I know that the user is still going to see a "Site Offline" message.
Thanks again!

Hi,
I am very new to Ajax and was trying to use ajax control tab in asp.net.
I downloaded the Ajax toolkit 3.5 and added them in the toolbar. then i use the toolbar as follows in my ascx page.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Default.ascx.cs" Inherits="MyProject.Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:TabContainer ID="MainView" runat="server" ActiveTabIndex="3"
Width="594px">
<asp:TabPanel runat="server" HeaderText="Submission" ID="TabPanel1">
</asp:TabPanel>
<asp:TabPanel ID="TabPanel2" runat="server" HeaderText="Transfers">
</asp:TabPanel>
<asp:TabPanel ID="TabPanel3" runat="server" HeaderText="Errors">
</asp:TabPanel>
<asp:TabPanel ID="TabPanel4" runat="server" HeaderText="Messages">
</asp:TabPanel>
</asp:TabContainer>
when i run it, it gave error like this:

Hi,
I have a list of doc files located on a server, I need to open them on a client side in asp .net form.
I don't want the users to be able to enter the directories or the files (security permissions) directly,
\\servername\c$\directory name, so I removed all security permissions, but I still want the users to be able to open
the files from the web site, can you help me?
thanks,
Yefi

You can receive the filename by a querystring.
string filename = Request.QueryString["filename"];
Then you can validate everything you need and, if the file is a simple textfile, you can open it and write all its contents to the page.
You can even do this with other file formats, but then you must set the document type and maybe need to use a page only to "download" the file.
|
|
|
|

Not good for me, if the filename permissions on the server are minimum I can't open the file.
|
|
|
|
|
But not even the code running at the server side is able to open the file?
If that's the case, it will be impossible to solve.
I think what you want is something like this:
Direct connections to a folder or http folder: They are not able to access the files.
Connections to a page - Such page will be able to see only files located at "some directory". If "some directory" is protected from reading, you may need some type of impersonation.
But, then, the flow will be:
Clients (without any access) will access your page at the server.
Such page will have some type of impersonation, can verify if the file only contains the names (no .., no drive letter and so on) and, even then, it only has access to one directory. It reads the file (if valid) and then returns its contents.
If you need, I can detail better about impersonation, but I don't think that you will really need that.

First you need to give the user some way of selecting which file they need to open. This can be done through may ways, may be you list all the files on you page?
Once a user selects (knows) which file they want, they don't permission on the server side. But asp.net will definitely need a permission to read/access the files from that folder. If asp.net does not have permission then it will fail.
|

In order to open the document on the client side, the encoding must be set to an appropriate type for the relevant document. The thing you need to set is known as the MIME type, for instance - if you want to open up an Excel document, the content type should be set to application/vnd.ms-excel. I hope that this helps.

Hi,
is there anyway to create dynamic variables at the runtime based on a
string input from another function
string datatypestring="int";
using this datatypestring i need to create a integer variable at run
time.is there any methods available in reflection to create dynamic
variables(like int, double etc)
|
|
|
|
|
|
Yes, there is, but you must first get the real type (or must do conversions by your own).
Type type = Type.GetType("System.Int32");
object value = Activator.CreateInstance(type);
But note that I am using "System.Int32" and not "int". For double, you must use "System.Double".
After creating it, it returns as object, but casting it will work.

You may want to distribute 'release' version as opposed to debug version

But you heading says asp.net dll. So which one is it?

If this is .net dll you don't need to register it, on the other hand if it OLE control or ActiveX then make sure regsvr32 directory (System32 dir) is in your path. Try the full path if needed.

This is an indication you don't need to register the dll

Hi all, I need to develop a progress bar in my web application which is in asp.net. This progress bar should see on screen while switching to new page of my application.
I have master page in which i have created diffrent menues.. like Audit,Manual,Update
on click of tht different pages will get disply.
so i want to disply progressbar on click of those menus
<td id="tdmnuPerfRating" valign="middle" align="center" style="width: 200px; height: 25px;
background-image: url(./images/grey_bg.jpg);" onmouseover="javascript:changecolor(this,'on');"
onmouseout="javascript:changecolor(this,'off');">
<asp:HyperLink ID="HyperLink3" runat="server" CssClass="CSMenu" Text="Performance Rating"
NavigateUrl="~/ViewAudit.aspx" />
</td>
<td align="center" valign="middle" style="width: 1px; height: 25px">
<div style="display: inherit;">
<img src="images/line_vertical.jpg" border="0" alt="Line" height="25px" /></div>
</td>
<td id="tdIssue" valign="middle" align="center" style="width: 200px; height: 25px;
background-image: url(./images/grey_bg.jpg);" onmouseover="javascript:changecolor(this,'on');"
onmouseout="javascript:changecolor(this,'off');">
<asp:HyperLink ID="HyperLink27" runat="server" CssClass="CSMenu" Text="Issues"
NavigateUrl="~/ViewIssues.aspx" />
</td>

Firstly, in the future when posting code snippets please format them using the "code block" menu item.
You will not be able to have the progress bar remain while navigating to another page in this manner. Remember the web is stateless so each request is rendered new to the browser, thus closing the current displayed page.
