subscribe for the OnBeforeExpand event.

I use a process in which I first only load the first three "generations" of the treeview. Then in the BeforeExpand event, I populate that node's grandchildren. Therefore, any time the user sees a node, it always shows its expand icon (the [+]) if it has children.

I am about to start writing some components in .net that will need to interact with an LDAP directory (Not MS Active Directory!)
Can any one send me any pointers?
Thanks

The following code loads the contents of a web page (Page) into string PageText:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(Page, true));<br />
request.Method = "GET";<br />
<br />
HttpWebResponse response = (HttpWebResponse) request.GetResponse();<br />
Stream responseStream = response.GetResponseStream();<br />
StreamReader reader = new StreamReader(responseStream);<br />
string PageText = reader.ReadToEnd();
The problem I have is that the page I receive comes back with encoding that doesn't show up correctly in a text box. For example a single quote ’ comes back as & # 8 2 1 7 ; (without the spaces). I think that this would be correctly displayed in a HTML viewer, but how do I get it to display correctly in a text box?
Putting an encoding in the constructor for the StreamReader seems to make no difference.
Thanks in advance,
Keith

Would the System.Web.HttpUtility.HtmlDecode() method work?
|
|
|
|

This is a C# application and not ASP.NET code or a WebService. Therefore I don't have access to the System.Web namespace. Sorry, I should have mentioned this first time.
Thanks for the response.

Did you tried System.Net.WebClient?
<br />
using System.Text;<br />
using System.Net;<br />
<br />
...<br />
<br />
WebClient request = new WebClient();<br />
string PageText = Encoding.Default.GetString(request.DownloadData(Page));<br />
Cheers,
John

I've tried this but the result is exactly the same regardless of the encoding.
|
|
|
|
|
What happens if you use:
<br />
...<br />
string pagetext = Encoding.ASCII.GetString(request.DownloadData(Page));<br />
...<br />
Sorry if you already have tried it... 
|
|
|
|
|
I tried Encoding.<everything I could think of>.GetString all to no avail. 
Actually .ASCII makes things slightly worse!

It seems that you're getting an unicode encoded page from the web server. Did you tried Encoding.Convert?
<br />
using System.Text;<br />
...<br />
string pagetext = Encoding.Default.GetString(Encoding.Convert(Encoding.Unicode, Encoding.ASCII, request.DownloadData(Page)));<br />
...<br />
What language is your web page/web server? You may try to change Encoding.Unicode to other encoding like UTF8, and Encoding.ASCII to UTF8 if you're still getting wrong results. I'm using the default encoding to read web pages in english/portuguese, and the results are ok for me.
Cheers,
John

You need to initialize your object within the application, try adding something like the following, possibly in InitializeComponent().
this.YourObject1 = new YourObject();

Hello NG,
I have a standard C# Class-library Project and want it to behave like the SQl-Connection User Control. Means you can drag it from the toolbox on a form and it docks underneath the forms designer.
Does anybody know how to achieve this?
Thanks in advance

I am pretty new to C# and the .NET fromework for that matter. I have recently began working on a Binary Tree class and would like to be able to store any type a user wants to store (i.e. Object). I would like to hide the implementation of this class from the user, however I am having trouble discerning what type the data is that is being stored in this class. I would like to be able to do some sort of "dyanmic cast" on the data and call the appropriate CompareTo() method. I would like to not have to always test on the type of the data and then cast the data to that specific type.
Is this possible?
Hope this makes sense!
Any help would be greatly appreciated.
Thanks
Michael

Look up typeof. It will do what you want.

Or just myObject.GetType();
Yeah, but don't you have to say
if (myobject.GEtType() == typeof(desiredtype)) ?

typeof is just going to return the same thing as .GetType() will. They both have System.Type return values.
And, if you look at the remarks on the typeof page:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfTypeofPG.asp[^]...they say that in order to obtain the runtime type of the object, you should use GetType()
So the question is...what are you passing into typeof()?
[edit]Ah, I see now. The example makes it much clearer. You pass the name of a class into typeof(). GetType() returns the type of an object.[/edit]
[edit2]Besides, why wouldn't he just use the is keyword? if(myObject is Object)[/edit2]
