They are assuming you're using a standard TextBox control.

You appear to be using a third party control. Check the documentation on the control or contact the people who wrote it for support.

I've never used it...

Is that possible? I want to try Session variable but I think it cannot detect by another application that will receive it. Any idea with here guys? Thanks in advance! Confused | :confused:

There must be a unified channel. Place each of those data into database and access data for both the solution to the same database. Thus giving a way to communicate.

In case of chat rooms, each of users connect to server to a specified id(chat room id) and whenever an update to the dataset takes place, updates are sent to each of them.

You might ping the server using AJAX call and see if any update is available to that id and update UI accordingly. Wink | ;)

Reflection

I have a following structure

App_Code
   MyClass.cs [Company.MyNameSpace.MyClass]
Bin
   MyLib.dll [Company.MyLibNameSpace.LibraryClass]

From Company.MyLibNameSpace.LibraryClass I need to create an instance of Company.MyNameSpace.MyClass, but I don't know Class name until execution (it comes from XML configuration), so I use Reflection for it:

Type type = Type.GetType("Company.MyNameSpace.MyClass")

The problem is, that when I load a Type from DLL, it doesn't work (type == null), when I do the same from another .cs file in App_Code folder, everything works fine. Is there any work-around to this problem?

As you dont have reference to Company.MyNameSpace.MyClass, you need to manually read the assembly using Reflection and then using Activator.CreateInstance you create the instance of the class.

For instance :
Assembly assem = Assembly.Load("\folder\MyLib.dll");
object thisObj = assem.CreateInstance("Company.MyNameSpace.MyClass");

ASP.NET web project -> native DLL -> write failure to hdd

I've got ASP.NET web application which uses native DLL in C++ wrapped in C# using PInvoke.
Native DLL needs read/write access to specific folder in site location on hdd.
How to enable it?

e.g. in ASP.NET to enable C# write access to specific folder it needs to allow user to have write access to that folder from folders properties.
with native dll that does not work.

How to register a click event when clicking on a node of a treeview that is already selected

Man Pang13-Nov-09 5:22

13-Nov-09 5:22

When a node in a treeview is clicked, a SelectedNodeChanged event is fired if and only if the node that is clicked is not the same node as the previously selected one. However, if I click on a node that is already selected this event is not fired. Does anybody know how I can find out the node that I had clicked on in this instance.

I can use javascript to trap the onClick event but I still don't know how I can find out which node I clicked, in particular, the ValuePath property of the node.

Thanks, in anticipation.

Access specifier for method

sris 42613-Nov-09 2:37

Deal all,

I have a method in my aspx.cs file say methodone,which will be called from one of the event or method from the same aspx.cs file...

So what access specifier i can give for that method.I am thinking private is enough for my requirement. AM i correct / wrong? Please provide your views...

Thanks,
Srinivas Mateti

If you want to access the method from your html page, you need to make it at least Protected.

I mean if you write
<asp:textbox OnClick="txt_Click" runat="server" />
the txt_click should be made at least protected. Privates cant be used in events.

If you are just calling the method from the class itself, you can use Private. Rose | [Rose]
