Of course they have. People have contradicting opinions about everything from application architecture to placing of brackets. Stored procedures is not an exception.

There are a lot of arguments there why stored procedures aren't better than dynamic queries, but that does neither make dynamic queries better nor stored procedure bad.
They are simply different approaches, so they have different strengths and weaknesses.
I prefer stored procedures, because:
:: The queries gets separated from the code. Things that has different purposes often benefit from being separated.
:: There is a well defined interface between the stored procedure and the code that is using it.
:: The execution plan of a stored procedure is always the same, so you know that they cache well. The execution plan of a dynamic query can change in ways that is hard to predict. It's easy to try out a stored procedure to see the execution plan, but not as easy to try out every possible dynamic query that the code can create.

Hello everyone, am new to visual web developer. am using vb.net and i have AJAX control toolkit installed. Am developing a website and would like to make menus that bring out their contents once you hover on them, like the way menus on www.microsoft.com website are.
Thanks for the assistance, anyone will render.

Unless the AJAX toolkit offers such a menu ( and I don't see why it should, a menu is not an AJAXy thing ), you will need to find a third party DHTML menu and integrate it into your project.

Thanks a lot Christian, but are you sure you cant recommend a third party DHTML menu creator that I can use? hopefully a free download

I know there's tons of free downloads. I am using none of them If I were, I would have gladly recommended based on my experiences.

Hi,
is it possible to record inside a web application the input from the microphone and send this data to the web server? Maybe with adobe flash or a java applet? Has anybody created something like this?
Thanks

Yes, it's sure possible with a .NET or Java plug in. Not sure about flash. I've not done it, no

Hi... we need a component/script that will do a bandwidth speed test on a closed network. That is, the client PCs having their bandwidth speed tested will not have access to the Internet, only to the server that the test should be run against. Component/script can be Javascript, ASP, ASP.NET, ActiveX, Flash; no PHP or CGI or any other scripting language. Of course a free component/script is optimal, but the budget might support something inexpensive.
Any ideas? Thanks... Steve

Hi,
I am adding a table dynamically using c# as below:-
productCell = new TableCell();
KSSCheckBox checkBox = new KSSCheckBox();
checkBox.ID = string.Format("CheckBox|{0}|{1}", x, product.OwnProductUID);
checkBox.Description = "Update";
checkBox.Checked = false;
checkBox.Attributes.Add("onClick", "HighLightCell();");
productCell.Controls.Add(checkBox);
productRow.Cells.Add(productCell);
When the user clicks the CheckBox I have to call a JS function which will highlight the table cell, and then do the reverse if the user unclicks the box again.
Trouble is I'm new to Javascript & dont really know where to start, have read plenty of examples on the Web but all of these are adding the code in the front end pages - I want to add this in code behind window.
I am including a .js in the page.aspx, which contains:-
function HighlightCell(cell)
{
Cell.style.backgroundColor = "#E0E0E0";
}
But this never gets fired when I click the check box?
Any help will be appreciated.
Thx
Janet

It looks like there are 2 problems with your code.
But_Im_a_Lady wrote: checkBox.Attributes.Add("onClick", "HighLightCell();");
Your call to HighLightCell should pass a single argument representing a reference to the cell to update. This should read something like
checkBox.Attributes.Add("onClick", String.Format("HighLightCell({0});", ProductCell.ClientID));
But_Im_a_Lady wrote: function HighlightCell(cell)
{
Cell.style.backgroundColor = "#E0E0E0";
}
JavaScript is case-sensitive. You should change Cell to cell otherwise the interpreter won't know what is being referred to here.

Hi
I have a hard time changing my generated xml content from "UTF-8" to "ISO-8859-1".
Is there a way in code behind to change it ?
Example:

You will have to re-post with the Ignore HTML tags check box check since we can't see your example code. If you are serializing objects to get your XML (which I hope you are) you can set the encoding before you serialize to whatever encoding you want. Just make sure that whatever is de-serializing the xml is using the same encoding or you will have problems.
By the way to get the encodeing:
Encoding.GetEncoding("iso-8859-1")
So then you just need to set your encoding on your serialization object. That is slightly different based off which version of .net you are using and how you are serializing your objects.

This is my sample code:
Dim settings As New XmlWriterSettings()
settings.Indent = True
settings.NewLineOnAttributes = True
Using writer As XmlWriter = XmlWriter.Create("C:\xmlfile.xml", settings)
writer.WriteStartDocument()
writer.WriteStartElement("MYXML")
writer.WriteStartElement("PART1")
writer.WriteStartElement("Action")
writer.WriteValue("test")
writer.WriteEndElement()
writer.WriteStartElement("test1")
writer.WriteValue("test")
writer.WriteEndElement()
writer.WriteStartElement("test2")
writer.WriteValue("test")
writer.WriteEndElement()
writer.WriteStartElement("test3")
writer.WriteValue("test")
writer.WriteEndElement()
writer.WriteEndElement()
writer.WriteEndElement()
writer.WriteEndDocument()
writer.Flush()
End Using

So it is easy then. Just add
settings.encoding = Encoding.GetEncoding("iso-8859-1")

Oh, that's how it will be added. I tried it using the settings.encoding but I've got the error before because of the wrong syntax.
Anyway, it's working fine now. Thank you

Hi,
I have a problem handling session variable.
How can I control the session variable from expiring? Is there any properties to be added in each page or to be added in web.config?
Thanks
hifiger2004

Hi,
You have to create them (declare) in the Global.asax file in the Session_start() event.
E.g.
Session["Name"] = "";

Hi,
I encounted this problem when the the browser or the computer is idle.
Error message below:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machinekey>
configuration specifies the same validationkey and validation algorith. AutoGenerate cannot be used in a cluster.

Or is there a way to handle the error so I can change the error message?

In the web config file there is a section that you can put the timeout in:
<sessionState mode="InProc" timeout="30"></sessionState>
In the example above it is 30 minutes.
Now there are some other things to consider. Your application pool that your web site runs under by default recycles every 27 hours. Everytime that happens you will lose your session. First is is always a good idea to change your application pool recycle time to some time, perhaps early in the morning 2am, 3am when users are not using your site. Again if you application pool is getting recycled it will end your session. All of this is assuming that you are using InProc as your Session Mode. That means the Session info is stored on the web server. There are other options which would allow you session to last longer. One option stores session on a different server and the other option stores it in sql server. These each have ther advantages and disadvantages.
I would think long and hard before you decide to increase your session timeout to a large number. I really don't think you want to keep your session around for longer then an hour or so. If someone has not actively used your site in an hour you should timeout their session. They are using up resources that others could be using.
Hope that helps.
Ben

Ok, it sounds like your web application might be hosted on a web farm. If this is true you must select a different mode for session state other then InProc which is the default. If you are using InProc and you have a web farm or cluster what can happen is a user starts there session on one web server and the session info is there, then on their next request the go to a different web server which doesn't have the session state info. That would be why you are getting your error. You need to look at having a sessions state server or store session in sql server.

Yes, you are right
But how can I catch the error so I can inform the user that the browser needs to be refresh. I will inform the user thru the msgbox.
