- TIP: httpRuntime executionTimeoutI had noticed a number of people posting that they where having
trouble getting the Web.config httpRuntime executionTimeout attribute
to work as expected.
I realized today that if the compilation debug attribute is set to
"true" in the configuration, then the framework doesn't seem to
timeout requests (probably because this might be annoying if you had a
debugger attached and were stepping through code).
It would be nice if the MSDN documentation for the executionTimeout
config attribute referenced this dependency. A similar thing that
threw me for awhile was that a trace="true" at the page level seems to
implicitly cause a No-Cache directive to be issued in the response.
Hope this helps someone.

- Multi-threaded HTTP ModuleAll,
I am trying to write a multi-threaded HTTP module that handles the
OnBeginRequest and logs it. What I am trying to do is to offload the
logging to another thread which will allow the http module to release
the OnBeginRequest.
The issue that I have is that I keep on getting "Request is not
available in this context" exceptions.
The following is the code I am using:
using System;
using System.Web;
public class ProcessRequest
{
public HttpApplication HttpRequest;
public void ProcessingThread()
{
try
{
string sRequestUrl;
if (HttpRequest.Request!=null)
{
sRequestUrl=HttpRequest.Request.HttpMethod;
System.Diagnostics.Debug.WriteLine(sRequestUrl);
}
}
catch (System.Exception ex)
{
throw ex;
}
}
}
public class HttpRequestLogger : IHttpModule
{
protected System.Collections.Queue oHttpRequestQueue= new
System.Collections.Queue();
protected bool bModuleRunning =false;
public HttpRequestLogger()
{
}
// In the Init function, register for HttpApplication
// events by adding your handlers.
public void Init(HttpApplication application)
{
application.BeginRequest +=
(new EventHandler(this.Application_BeginRequest));
application.EndRequest +=
(new EventHandler(this.Application_EndRequest));
}
private void Application_BeginRequest(Object source, EventArgs e)
{
// Create HttpApplication and HttpContext objects to access
// request and response properties.
System.Threading.Thread oProcessingThread;
HttpApplication application = (HttpApplication)source;
ProcessRequest oRequestProcessor=new ProcessRequest();
oRequestProcessor.HttpRequest=application;
oProcessingThread =new System.Threading.Thread(new
System.Threading.ThreadStart(oRequestProcessor.ProcessingThread));
oProcessingThread.Start();
}
private void Application_EndRequest(Object source, EventArgs e)
{
// HttpApplication application = (HttpApplication)source;
// HttpContext context = application.Context;
}
public void Dispose()
{
}
}

- problem with multithreading and Web services method invocationHi:
I have an ASP.NET page which makes a synchronous Web services method
call. At the same time, however, I wanted it to load another page as an
iFrame (i've also tried as a javascript popup window) - this second
page is responsible for polling a DB and continually updating its text
box display.
The problem is that once the Web service call is initiated, the second
page becomes unresponsive exactly until the call is completed, when it
resumes. I'm baffled as to why this second page's request should have
anything to do with the first one's Web service request. I've tried to
encapsulate the time-consuming DB queries of the second page into a
separate thread and this works great (I tested it by printing a
timestamp to a file), but I also need a way of updating the display in
real-time while the Web services call is going through. Are there any
ideas as to how I can accomplish this?

- shopping cart binding to datagridHi,
I'm wondering if there is a way to bind to datagrid or a gridview the
items in an arraylist. These items all have vars such as price,
qty..etc? (besides putting in a datagrid or datatable first).
ex.
ArrayList alShoppingCart = shoppingCart.GetCurrentItems;
alShoppingCart contains an array list of Item objects.
Thanks

- VS mangles HTMLOn one of our projects, using vs2005 professional, Visual Studio reformats
the html in an aspx page so that it is virtually impossible to work with -
although it still executes properly. For instance it takes well formed html
that is indented for readability and converts everything to uppercase and
removes all carriage returns.
it converts this...............
<table>
<tr>
<td> vAlign=top>
<asp:panel id="LEFTPANEL" runat="server" Width="400px">
<table... . . .
to this..........
<TABLE><TBODY><TR><TD vAlign=top><asp:Panel id="LEFTPANEL" runat="server"
Width="400px"><TABLE
The page is then full of errors saying that uppercase is not valid.
I don't recall this every happening before but it is happening on this
project. We don't know of any settings that have been changed.
TIA,
Gary

- Getting control of Items within a DatalistI have a problem as I have placed a dropdownlist in a datalist.
Whenever the selected index changes I need to change a label inside
the datalist.
The problem is I can't get control of the label.
When dropdownlist changes it goes to a function with args of
systemEvent than a DataListItemEventArgs so I have no way getting
control of the item in the datalist to change the label.
Can someone please help me.

- not properly authenticating?hey all,
i have a simple asp.net app that using window authentication integration and
disallowing anonymous users.
well, when a user tries to browse to this page she gets a "The page cannot
be displayed error." I figured I'd at least get the asp.net error page.
any ideas?
some environment notes:
windows 2000 server sp4
windows 2003 r2 sql server 2005 sp4
xp pro sp2 vs2005 sp1 is my dev
xp pro sp2 is the user's machine with nothing but ie on it.
i'm thinking it's the user is not properly authenticating to active
directory because when i changed iis settings for the app to allow anonymous
the user can get to the page that way. but i'm not user how to troubleshoot
this if this is the case.
thanks,
rodchar

dotnet-framework-aspnet, Understanding/explaining WebZones....
The SDK has me a bit confused with respect to WebPartZones and the sections
within them. The SDK page for the WebZone has s table that lists the sections
within a zone: header/body/chrome/part controls/footer.
I get the header and footer sections, but the other three are a big hazy
to me... please correct these statements where appropirate (as I don't think
I have it just right). Two (part controls & chrome) of the items listed as
"sections" doesn't quite make sense to me as they seem to be more of categories/labels
than sections.
The body is essentially everything in the WebPart sans header and footer.
The Part Controls are essentially any controls added to the zone... correct?
The chrome is all the UI components/elements within the zone... correct?
If so, then why call chrome & part controls a section?

- Session Time Out Issue In ASP.NEtT hosted in Windows 2003 Enterprise EditionDear Gurus,
My ASP.NET website is running on .NET 1.1. hosted in windows server 2003
enterprise edition. We are having two sites. They are
1. One internet site
2. One intranet site.
Both these sites are having same aspx pages. No difference at all
between them in page content.
My business logic is hosted as web service which is running in the
intranet site. My intranet site web server also hosts a legacy web speed
application whose authentication is controlled by the new ASP.NET
application. This is being achieved through setting some cookies.
Most of my ASPX pages are popup pages.
We are facing one peculiar problem in the intranet site. After
authentication When ever a user clicks any one of the links of the popup
windows the session is getting timed out. But when we navigate with
normal pages this does not happen.
This problem occurs only in the intranet web server where my web
service and the legacy wep speed application is hosted.
The same asp.net code which is hosted in internet web server does bot
pose any problem.
Last time when we had this prolem we have replaced the dlls which are
working fine in the internet site to the intranet site virtual
directory. Then this problem was solved. But now after some time this
problem is coming again in the same pattern.
Could any one thorw some light on this?
Early response is appreciated.
with regds,
Vasu

- How to save a TreeView?Hi Experts:
I'm using ASP.NET 2.0. I'm using a TreeView control with a design-time
configured XmlDataSource (an XML file). I use the TreeView control as a
"message board" with each node representing a message. I noticed that the
TreeView loads alright from the XML file but did not save anything. I call
the TreeView.Save() for each new node added into the TreeView. What I'm
missing here?
Thanks in advance!

- TemplateColumn & BoundColumnA DataGrid can be changed to the editable mode by using a
TemplateColumn (say, with a Label in the ItemTemplate & a TextBox in
the EditItemTemplate) as well as by using a BoundColumn (which will
automatically change to a TextBox when the DataGrid is in the editable
mode).
So when should a TemplateColumn (with an ItemTemplate & an
EditItemTemplate) be used & when should a BoundColumn be used?

- dynamic webservice creationHi all,
Is it possible in .Net 2.0 to host a Webservice without ISS? Yes, I've
seen the articles and saw it was possible, but I would like the
webservices to be dynamic and be created at runtime, including the WSDL
creation and execution. Suggestions are welcome.

- Forms Authentication across directoriesI have an application on my local machine that has a 'Manager' folder which
holds the content management/admin pages to the site. I'd like to administer
forms authentication for the pages in this folder alone. Do I have to make
this a new application in IIS? If so, can I use user controls in the main
application?
Thanks,
Nathan

- How to show more error message?I use these setting in Web.Config
<customErrors mode="On"
defaultRedirect="~/ErrorPage/GenericErrorPage.aspx">
<error statusCode="403" redirect="~/ErrorPage/NoAccess.aspx"/>
<error statusCode="404" redirect="~/ErrorPage/NotFound.aspx"/>
<error statusCode="500" redirect="~/ErrorPage/InternalError.aspx"/>
</customErrors>
The error of Code 403 and 404 is clear and it will transfer to a assigned
page.
But when the error StatusCode is 500 or not defined, I want to show
something more detail to user on the errorPage.
I have tried string sMsg = Server.GetLastError().Message in
InternalError.aspx and GenericErrorPage.aspx,
But the GetLastError() always return null.
How can I do?

- Cross page data: Session, Viewstate or something else?Hello,
I have a webapp with on each page a "language" drop down list. Now, if I
choose X, I want to initialise the drop down list to X. Easy to understand.
But what is the best way to do this in ASP.NET? The obvious answer is, I
think, the Session object. But one thing annoys me: a session can expire. It
is difficult to guess the expiration time; 20 minutes, 40, 60? I just don't
know. Is there a better way to pass data between pages? I was thinking about
the good old url parameters: page.aspx?language=en. But I don't think that's
the ASP.NET way.
Ideas, suggestions and comments more than welcome.

- Trying to show a Crystal Report at WebForm1.aspxTrying to show a Crystal Report at WebForm1.aspx:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
If Not Page.IsPostBack Then
showReport()
End If
End Sub
Private Sub showReport()
' Filling DataTable
'...
crReportDocument.SetDataSource(MyDataTable)
CrystalReportViewer1.ReportSource = crReportDocument
End Sub
Crystal Report shows on the web page very well. But if you click on
link page number 2, trying to get the next page, WebForm1.aspx will be
reloaded again, as page.ispostback. Then I can't see any more pages but
page1 of my Crystal Report. How could I show a Crystal Report, please?

- Can someone ExplainRun at server and Client javascriptsHi
i'm still getting my head around developing in a web environement.
I have a server button. on the load Page_Load event i use the following code
to register a client script.
btnReturn.Attributes.Add("onclick", "javascript:NewPatient()")
one thing i've noticed is that although the code fires it still seems to
come back to the server. (i had assumed that if their was only javascript
event it would only run at the client. But if there was both then it would
run first at the client and then the server)
I used a html button and in its onlick event it fired the same function but
did no do a postback to the server.
Can someone tell me a site that explains in numpty language what is going on
and how to create client side scripts/ assign them correctly.
Cheers

- FormsAuthentication and Local Intranet ZoneI'm a bit stumped by this one: It seems that when I connect to my
application using the server's intranet name (http://intranetserver/MyApp/)
FormsAuthentication kicks back the user to the Login page after I call
RedirectFromLoginPage. It works fine if I access the server by IP address
(http://xx.xx.xx.xx) and if I access the server over its public domain name
(http://www.myserver.com).
Why is this happening?
I have IIS set to Anonymous Auth. Windows Auth is disabled. My web.config
auth section looks like this
<authentication mode="Forms">
<forms name=".MyAppAuth" loginUrl="Logon.aspx"/>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
