Web Services can't return unknown(generic) types, a web service should explain it self all the time.
It means that what you are doing is not a good a idea
<br />
<WebMethod()> Public Function Test(ByVal sl() as TestList ) As String<br />
Return sL(1).Value.ToString<br />
End Function<br />
From application AppTest:
<br />
Dim param() As New ArrayList<br />
param.Add(New TestList("N1", "V1", "T1", "S1"))<br />
param.Add(New TestList("N2", "V2", "T2", "S2"))<br />
Response.Write( ws.Test(parm.ToArray( GetType(TestList) ) ) )<br />
I am assuming implicit convertion on of the Array with the array list but you can cast that array to any type you want before passing it to the web service.

Thanks for your reply.
When I tried your code and got the following error:
error BC30311: Value of type 'System.Collections.Generic.List(Of AppTest.ParmList)' cannot be converted to 'Integer'
By the way, on both webservice and application side I have a generic class TestList. It's not unknow type.
Thanks.

Hi
I have a RadioButtonList Control and I dont have any Item selected.
Is there an instruction that validates if you selected an Item or Not from this RadioButtonList Control???
I would expect something like this in VB:
RadioButtonList1.AnyItemSelected=True
Any ideas??
Thanx ¡¡

Armando, you need to test your radio button list items using a foreach statement... Im more confortable with C#, if you are a VB person try to convert the below code to VB syntax
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
foreach (ListItem li in RadioButtonList1.Items)
{
if (li.Selected == true)
{
//execute some instruction
}
}
}
}
Le me know if you are still confused

I'm trying to instantiate a class by name.
The class is in my projects namespace and located in a file in the App_Code folder.
Basically I am calling :
Type tip = Type.GetType("PortalModuleControl");
where PortalModuleControl is the mentioned class;
But tip returns null.
Isn't Type.GetType supposed to look for the definition of the class in the current assembly?

Yes what you are doing is not right...
Here is a the rith way:
<br />
Type type = Type.GetType("MyNameSpace.TheWholeThing.MyClassName, MyNameSpace");<br />
MyAssemblyName issually is the same as the namespace, for instance but not always:
<br />
namespace TQU.Demo{<br />
public class Test2{<br />
<br />
}<br />
}<br />
<br />
namespace TestingTypes<br />
{<br />
class Class1<br />
{<br />
<br />
<br />
[STAThread]<br />
static void Main(string[] args)<br />
{<br />
Type type = Type.GetType("TQU.Demo.Test2, TestingTypes");<br />
}<br />
}<br />
}<br />

Type type = Type.GetType("myNameSpace.PortalModuleControl, myNameSpace");
doesn't work either.
I have only one namespace in my application.
I'm dealing with an ASP.NET application. Are there some restrictions regarding this?

Type type = Type.GetType("myNameSpace.PortalModuleControl, MyAssemblyName");
Can you tell me if your namespace is the same as your assembly name.
What's your assembly name?

Hmm, I'm guessing it is. My Asp.Net application is running using the ASP.NET Development server which from my understanding acts like IIS and precompiles the code while running. I tried deploying the application but there's no DLL in the bin folder 
Anyway, from my understanding the assembly doesn't need to be specified when you use Type.GetType. Only when you use Assembly.GetType
Am I wrong?

Buddy u got all wrong.
If you don't see the dll in your bin directory it is because either you did not compile it
or you are getting a compilation error.
ASP.NET does not compile the ASP.NET code in runtime, .NET compiles IL in runtime.
If you want to see the your assembly name right click the project and click properties, there are some tabs there one of them will have the assembly name.

I wish that was it. Unfortunately something goes wrong. Meaning the project builds, it runs, but when I publish it, the directory that I choose to publish to is empty. I have tried all options in the publish dialog and the result is the same.
Aparently others are experiencing this, too. No I just need to have a solution that aparently others didn't find
Felipe Dalorzo wrote: ASP.NET does not compile the ASP.NET code in runtime
The App_Code folder and its special status in a web application allows you to store classes that will automatically be compiled at run time.

Hi all
From last 30 days i have been searching for a tool or any mechanism through which I could print reports in my asp.net 1.1 application in a proper format.
I tried Crystal reports but in this one can print report only by exporting them into pdf .. and obviously its not a solution.
what I want is if I print a report (say have 1000 records) then the data grid header should be shown on all pages, instead of only on first page.

What do you mean by this? Is it that you don't want to do any conversion before your reports are printable?
cdotpal wrote: then the data grid header should be shown on all pages, instead of only on first page.
This is possible without getting any reporting tools. If you just want people to be able to print out data from your web application, then look at this[^]. You can modify your data grid a bit and add some styles to get the header to print on every page.

thanks dustin, I havent got the solution yet but thanks for the useful information.

Try MS reporting services which can export in PDF, Excel, xml etc.....
Look where you want to go not where you don't want to crash.

I'm trying to play around with Lightbox (http://www.huddletogether.com/projects/lightbox2/). Anyway, I'm working on an existing site with a single master page. I attempt to add the following to my page:
<script type="text/javascript" src="~/js/prototype.js" runat="server"></script>
<script type="text/javascript" src="~/js/scriptaculous.js?load=effects" runat="server"></script>
<script type="text/javascript" src="~/js/lightbox.js" runat="server"></script>
Now, I get hundreds of build errors. If I take these links back out, they go away. I've found that it is because of the runat=server attribute (because if I take it out and use the "../" syntax, things work again). Now, I'd like to be able to reference these scripts using the "~/" syntax that is common in ASP.NET, but I can't figure out how to make that happen without build errors. Any ideas? It's not a particularly big deal, but I think it's important for me to understand WHY it doesn't work.
Thanks,
Will

client side javascript cannot run on a web server.
In order for the web page to be displayed the files need to be downloaded as well and the location of these files on your web server is either relative (../) or full (http://www.whatever.com/foldername/filename.js). As a web page downloads, copies of the support files - js, css, images etc are also sent therefore these files are now copied to the client.

Turns out that I had a misconception about how to handle this. I did need to use the "~/" trick for accessing the script file, but it turns out that you can use Page.ResolveUrl to use it without making the <script> block runat=server. My main issue was that when I made it runat=server that the runtime was attempting to parse the javascript file.

I have a three tiered asp.net application and in my Student_Results class - I have my properties set up like this:
Public Property Enumerator()
Get
Return m_intenumerator
End Get
Set(ByVal Value)
m_intenumerator = Value
End Set
End Property
I have a text box where the intenumerator is taken from on another form a popup: the value is saved to the session variable and then the save function of the class uses a stored procedure to send the info into the table of the sql database. The field in the database is set up to accept nulls but I have an error hitting in the property as it will not accept the null value.
I have this on my popup form:
If Session("Marks") Is "" Then
m_objStudent_Results.Enumerator = System.Convert.DBNull
Else
m_objStudent_Results.Enumerator = CType(Session("Marks"), Integer)
End If
How do I deal with this problem - the text box being filled in is not mandatory - the end user can either put something there or not and if not I want the value of null set back the table.
thx, Tammy

Tammy, you need to test your session variable for empty string AND null... believe me when I say that I learned my lesson the hard way 
Im comfortable with C#, so interpret this to VB syntax:
if (Session("Marks") != null && Session("Marks") != "")
{
//execute some instruction
}
else
{
//...now get the idea!

I'm embarrassed to say it but I can't spell to save my life some day's. Being a programmer this makes me look like a fool and even worse when I'm working with a web application. My boss has come to me and has asked me to find a solution to this issue of mine. I'm using VS 2005 Pro with the Adobe CS suit for misc. web and graphics features, plug-ins. Does anyone have an add-ins for VS 2005 for spelling within strings? My error messages, text within XSLT, and just in general.
I'm not having a bad hair day but a bad spelling day!
