vlusardi,
There is no built in way to do this, however a simple function like the following should do what you want:
private void CheckChildNodes(TreeNode ParentNode)
{
foreach(TreeNode t in ParentNode.Nodes)
{
t.Checked = ParentNode.Checked;
if(t.Nodes.Count > 0)
{
this.CheckChildNodes(t);
}
}
}

Don,
Thanks again, I knew I'd be doing some recursion if I couldn't find any built-in functionality, just didn't realize it would be that simple...

Hi All,
I have a base class and then a class that derives from it. In the base class I have a virutal function. My question: Since the function in the base is virtual why do I still have to provide the new or override keyword? I don't recall having to do this in C++ (although I could be wrong). Which one (new or override) is be better to use? Both fucntions return the same type.
//Just added
I just tried to add the override keyword and get this compiler error: A member marked as override cannot be marked as new or virtual
Isn't this sort of a catch 22 type thing?
When I remove it I get this complier error: ToolTabsCS.ToolTabSplit.InitializeTool()' hides inherited member 'ToolTabsCS.BaseTool.InitializeTool()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
Thanks.

In my article C# Keywords[^] I describe both and give some examples.
Hope that helps.

No. If you mark something as override then it's automatically virtual, if you mark it as new then it's completely hiding the base class implementation so you can decide to make it non-virtual.

Thanks for the replies guys. The problem was that I was keeping the virutal keyword in as well as override, didn't know you had to remove it. Thanks again.

 the virutal keyword will be picked up be anti virus scanners and your code wont compile

I have a project I am working on where I need to be able to programmatically search a remote SharePoint Portal Server for specific information. I would like to accomplish this using .NET, rather than going through Web Part developement (which at this point is a little over my head).
Has anyone run across a .NET wrapper library for SharePoint or some code that will allow me to interact with SharePoint? I found (I think here on CP) a set of classes that someone developed to interact with the Exchange WSS, but it seems to work only with that and not with SPS (which is based on the Exchange WSS).
Many thanks

SharePoint version 2 (which comes with Office 2003 beta 2), is written with ASP.NET. I'd think that would be what you're looking for.

Using various articles found here on CP I am putting together a small systray application to take a screen capture, resize it, and then upload to an FTP server.
I have everything working so far with the exception of the ftp upload, this is because this article :
http://www.codeproject.com/csharp/.net_ftp_upload.asp?target=ftp%7Cupload
Has a dead link, when you try an download the project files.
Does anybody know of any other articles of a similar ilk?

Hi!
(I hope this is the correct forum for this question)
I have a bunch of .net modules, written in different languages (managed c++ and c#). Now I'd like to link them all together into one .dll. I tried using al.exe, but this tool only generates an assembly manifest, that refers to the external modules rather than embeds them into the dll.
Then I tried this: I disassembled all modules with ildasm and then tried to re-assembly the .il files with ilasm into one final .dll. Hower this does not work, as my modules contain native functions.
What can I do?
Thanks in advance

Thank you for the link, but this exactly what I wanted to *avoid*: having the assembly split over several modules. Instead I wanted several modules to be physically embedded into one final .dll.
Let me explain my motivation:
I have a dll written in c++ with managed extensions. I use MC++ as I do a fair amount of IJW and COM-Interop. However, I need a collection derived from CollectionBase that reimplements object* get_Item(int) with a covariant return type (SomeType * get_Item(int)). As this does not seem possible in MC++ but well in C# (I posted my problem before: http://www.codeproject.com/script/comments/forums.asp?forumid=3785#xx455157xx), I decided to write the collections in C#.
So I would have a "main" dll e.g.
GentleStorm.Nasty.Graphics.dll
and a module with the collections
GentleStorm.Nasty.Graphics.netmodule
It would be nice if I could embed the latter into the first, so that I only have to distribute the .dll

Nice tool, leppie. However I need to link a mc++ module with native code as well  which is something that cannot be done using ildasm/ilasm.

Assume I want a client to use two different objects created in two different servers, what am i supposed to do? I want to know how i need to write my servers & client configuration files.

Hi everyone!
I want to write an application which has a server and some clients. I would like them to communicate with tcp/ip.
I would like to send and recieve all kinds of data.
I have read about TCPListener, TCPClient, channels, sockets sync and async methods.
What are the diffrences between those methods ? Which is the better way ?
Thanks.
|

If your wanting to talk RAW TCP/IP - then use the Listner and either the client or socket class.
Example:
TcpListener tcplpop = new TcpListener(110);
tcplpop.Start();
Socket s = tcplpop.AcceptSocket() // Blocks until someone calls
s.Send(...)
s.Receive(...)
|

What is the difference between version no.1:
TcpListener tcplpop = new TcpListener(110);
tcplpop.Start();
Socket s = tcplpop.AcceptSocket() // Blocks until someone calls
s.Send(...)
s.Receive(...)
and version no.2:
IPEndPoint dbg_EndPoint = new IPEndPoint(ipAddress, dbg_port);
Socket dbg_listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
dbg_listener.Bind(dbg_EndPoint);
dbg_listener.Listen(num_of_devices);
dbg_listener.BeginAccept( new AsyncCallback(AcceptCallback), dbg_listener );
// Get the socket that handles the client request.
Socket listener = (Socket) ar.AsyncState;
Socket handler = listener.EndAccept(ar);
// Create the state object.
StateObject state = new StateObject();
state.workSocket = handler;
handler.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReadCallback), state);
Thanks.

Hi
I want to do in C# what you can do in COM with custom catagories. In ATL I can implement a custom catagory in a class by adding the following macro:
BEGIN_CATEGORY_MAP(CEffect)
IMPLEMENTED_CATEGORY(CATID_EFFECTS)
END_CATEGORY_MAP()
and I can seach for class's that implement that catagory by using:
ICatInformation::EnumClassesOfCategories()
which returns a list of CLSID's of classes that implement the specified catagory.
Is there any way to do this in C#?

No. There is only one category in .NET, and it's hard coded.
Category GUID : {62C8FE65-4EBB-45e7-B440-6E39B2CDBF29}
Category Description : .NET Category
