If you are using Microsoft Ajax Framework you may use the CascadingDropDown[^] extender which does exactly what you are trying to achieve. Maybe it will be easier?

Guys,
We have a major problem here at work.
We installed a new product on our servers (Win 2000 server, 2Gb memory) last week, with an increase of users. (read, a couple of hundreds, not thousands)
At first sight it seems to work fine, but occasionally it crashes. other services stop as well.
My boss thinks that our code does not dispose of the connections we create, but I'm certain it does.
Also the cpu seems to be fine (so not constantly @ 100%) and memory does seem to saturate, but applications crash before that time.
My two cents go out to one of these two:
1 -> Network traffic problems
2 -> # of Oracle connections exceeded
Any tips and/or tricks or ideas somebody can give us would be great. We're kinda stuck.
I went over some possibilities already, but I always come down to the two mentioned above.
many thanks !!

Troubleshooting a production webserver is an involved process. You may need to go through a very systematic procedure like:
1) Analyzing the file system logs
2) System Eventlogs
3) Database Performance

hey thanks for the reply.
Stupid question maybe, but what's the difference between 1 and 2?
We did 2 already and it only gave some "unhandled Http request" error. nothing really specific.
thanks.

No. Not at all. The line of demarcation between your application logging events and System EventLogs may at times be very thin. Your application would log events strictly pertaining to any issues only related to it.
If there is a generic I/O problem or load with the system, that would be caught by IIS or OS Subsystem and placed in the eventlog.

Didn't you find any equivalent unhandled exceptions in your application log?

mmm, I didn't notice anything 'out of the ordinary' going on. The application seems to work fine, most of the time. We didn't see any significant errors in the application's log.
I'm trying hard to get some feedback from the users

Can you post the error you find in your logs?

Hello everybody,
I am vs2003 to develop my application. I created a web application. In that in one page I inserted data to a table. In another page I have to retrieve the values based on the date values. I write the following codings for that
txtdate.Text = Calendar1.SelectedDate<br />
Dim conn As New OleDb.OleDbConnection("provider=microsoft jet 4.0 ole db provider;data source=c:\internalaudit.mdb;")<br />
Dim cmd As New OleDb.OleDbCommand<br />
<br />
Dim dates As New DateTime(Calendar1.SelectedDate.Year, Calendar1.SelectedDate.Month, Calendar1.SelectedDate.Day, 0, 0, 0)<br />
Dim adp As New OleDb.OleDbDataAdapter("select * from auditfinding where auditdate = " + dates, conn)<br />
Dim dt As New DataTable<br />
'dt.NewRow()<br />
adp.Fill(dt)<br />
adp.Dispose()<br />
lstarea.DataSource = dt<br />
lstarea.DataTextField = "processaudited"<br />
lstarea.DataValueField = "checklistid"<br />
lstarea.DataBind()<br />
Calendar1.Visible = False<br />
I didnt get any error. Also I am not get any output. Can anyone help me. Thanks in advance.

Dim adp As New OleDb.OleDbDataAdapter("select * from auditfinding where auditdate = " + dates, conn)
replace the above code with
Dim adp As New OleDb.OleDbDataAdapter("select * from auditfinding where auditdate = " + "'" + dates + "'", conn)
I hope this will work

I do have the following structure.
I have an page (SamplePage.aspx). In this page is some stuff. At the top there are some filter elements which can be used to filter the list below.
The list is build with an <asp:repeater>.
So, because there are many other elements on this side it takes a little to make a complete server roundtrip and to build up the hole page again. If the user changes the filter I want only to reload the list.
So my idea is to use a webservice call, to generate the HTML for the table again.
How can I do that. My first idea was to put the repeater into an user control and to load the user control dynamically from the web service method with
Dim oPage As New CPageBase
oUC = oPage.LoadControl("SampleUC.ascx)
But if I do so, the created object is not completely initialized. The "Application" variable of oUC and oPage is Nothing. But I can see in debugger, that the Application in my webservice method is set correctly.
Do you have any ideas how to make that working. Or do I have the wrong beginning.
Thanks
Erik

Have you looked at the ASP.net AJAX extensions?
|
|
|
|
|
I am using .Net 1.1 and I think the extensions are only available for .Net 2.0 and higher.
I have no change to migrate to a newer .Net version now.
Is it also possible to make this with .Net 1.1?

Hi Friends,
Can anyone tell me how to use javascript variable from server side.
Thanks & Regards
Senthil Kumar
|
|
|
|

the way to do this is to put a hidden field in your page, set it's value with javascript, then read it on the server.
Or you could redirect to the current page, but put the variable name and value on the URL

Yet another idea would be to use cookies (set from JavaScript and read in ASP.NET). I would do the hidden field, though.
