Developing a network file backup application and need to
be able to see all machines on a network, select
drives/dirs/files for backup.... currently, I have an app
similar to Windows Explorer, with a treeview to look at
my own computer's data, with no problems... need to
add "My Network Places" to this (similar to Windows Explorer)
and be able to go out on
the network and get similar info for other
workstations.. plus I need to be able to create folders
and copy files to these PCs... I think I'm kinda close
with System.DirectoryServices and System.Management, but
can't seem to find what I'm looking for... any help or
suggestions would be much appreciated... thank you.

Is there someone who can tell me how to create the effect equivalent to Java's Flow Layout Maneger? In my concrete case, I would like to have a single column listview, where the elements are thumbnail images, similar to the standard UI presented by PowerPoint.
Thanks in advance

Is there a way to compile to native code rather to MSIL.
The problem with MSIL is its an open code, where everyone can just look at what you wrote, and beside that , native code will save the time of the compiling at run time, therefor it will be faster.
So is there a way to tell VS.NET to compile the code to native?

To try to get ahead on speed look into using ngen.exe.
Not sure if it affords any safty from decomp though, just a speed increase.
The only thing that can protect the IL is an obfuscator.

From what I have heard, you have an obfuscator part of the VS.NET 2003 package.

Can they span multiple assemblys (sp)? I am assuming that they can, but can’t seem to find anything that says definitively 'YES'. I will admit that it is late and I am probably not searching right on Goggle... but I just can't find it...
Also, Are there any recommendations for namespace hierarchies? I am considering:
[company_name]
[app_name]
[section_name1]
…..
[section_name2]
I assume that if I set the root namespace for each project to [company_name] then preced each class with the ‘namespace’ directive for [app_name] I can then nest the [section_name] namespaces inside of that.

'YES' 
This is used extensively throughout the framework, especially when you look at the assemblies that are meant to assist development (System.Design.dll).

Has anyone here used it for any projects?

I have been looking it over for a project and am looking for some other impartial views of it.

I've not used NUnit yet, but I do plan on including it with the development of my University degree's final year project (a big distributed commercial web service -- see a post below for a basic overview).
Anyway, NUnit is just a way of building automated unit tests, with the aim of producing a suite of tests that you can run to prove that the code does what it's supposed to -- and that anything you add hasn't broken something old.
The way I'm looking at including it from the outset (you add attributes 'n stuff ) is around a kind of one-person eXtreme Programming. By using these tests I can ensure to a certain degree that the code is successful, and should give me some good info to put in the report with regards to testing.
The other thing about XP (as far as I've understood it) is that one of the aims is to build elements of a system as quickly as possible, once its functional you move on. So I can do tests for features, once the tests complete ok I can move on ... there isn't a great deal of design involved before the coding.
I have to say its quite bureaucratic (including all this NUnit testing support) but I'm hoping it'll be worthwhile in the long-run, and should be a good learning experience.

Use NUnit (and NAnt which is awesome) for team development: daily builds and automated testing are essential whenever you're working with others on a project.
I didn't look into Log4net yet; i think it uses the pattern of Listeners which you can attach to a general logging system; just as you can do with the Trace classes in .NET

The "current node" is not the node that I am right clicking on to bring up the popup menu.
The menu handler looks like this:
private void mnuAddElement_Click(object sender, System.EventArgs e)
{
TreeNode tn=tvSchema.SelectedNode;
tn.Nodes.Add(new TreeNode("Element"));
tn.Expand();
}
And the node is correctly highlighted, but after adding the new node the highlight reverts back to whatever node was selected using a left click.
What do I do about this? I want it to work like it should--right clicking operates on the node that the user clicked on, not the last left-clicked node.
Help!

Thanks!
Almost works. The mouse position by this point is over the item the user clicked in the popup menu.
You led me down the correct path though, which is to write a mouse down event handler:
private void EventMouseDown(object sender, MouseEventArgs e)
{
tn=tvSchema.GetNodeAt(e.X, e.Y);
}
and save the node the user clicked on.
Note that it has to be a mouse down event. I tried mouse up, but that doesn't fire until the popup menu is done, and thus the mouse position is again wrong.

I've got a Windows Forms application (C#) and I have several cursors that I've drawn which I want to be able to embed in the application. I am able to load the cursors from a file, but not as an embedded resource.
Can anyone give me some pointers about how this is accomplished? I am using VisualStudio.Net.
Thanks.

Ok, this is going to be a little off-topic, but its a .NET Architectural-type question.
I'm working on the architecture to my University final year project, which is based around a commercial XML Web Service providing access to high performance analytics (courtesy of a third-party database).
However, it will also need to perform a number of menial housekeeping work too -- providing audit trails, reporting etc. It would be useful to have some kind of application that can effectively monitor the web-service too, i.e. current load that kind of thing.
I am considering using the following design:
ASP.NET Web Service <----> Windows Service <-----> Databases
With the Windows Service providing access to all the gubbins that hooks the web service together. That way, an administrative application can then access the windows service to get at the reporting info.
Does anyone have any opinions, or suggestions as to how this kind of thing might be done?
Alternatively I'd thought about adding filters using Microsoft's recently released Web Services Enhancements pack. Adding filters for logging requests etc.
All opinions would be greatly received,

Hi Paul,
Having this pipeline from Web Service -> Windows Service -> Database and back forces you to write (and debug) a lot of soap and remoting stuff (from outside to the WebSvc and back, from the ASP.NET Web Service to the Windows Service (remoting) and vice versa.
Consider the following approach:
Windows UI/Console client [*remoted]
|
Windows Service
|
v
Internet <---> ASP.NET <--> Busines Logic DLL <--> Database
^
|
Windows UI/Console client [*simple]
This way you can concentrate on core functionality by developing the Busines Logic Class Library and add all kinds of connectivity afterwards.

I'd like a "BetaExpiration" attribute (DECLARITIVE security) on my classes that is enforced automatically when the assembly containing the classes is used. A security exception should be thrown if the classes are being used outside beta period.
[AllowedUse(From = "2003-1-30")]
public class x
{
public x()
{}
}
CodeAccessSecurity permission is the way to do it and I've already got an test implementation. The major problem is that my custom CodeAccessSecurity derived permission assembly should be registered on the user's machine using CasPol etc for the .Net security system to find and use it. This is not desirable. The app should just be installed and my custom codesecurity access should be enforced...
Another way is implement another custom permissing, implement IPermission, ISecurityEncodable. Unfortunately, the declarative notation is never instantiated, unless I do it myself in code; the imparative method is working fine, but I'd like to use attributes for this!
public x()
{
AllowedUse2 au = new AllowedUse2();
au.From = "2003-1-30";
au.Demand();
}
Does anyone have a bright idea how to enforce custom CodeAccessSecurity using declarative notation without requiring .Net registration of the permission assembly?

On many newsgroups/forums have I repeatedly seen the question: "How do I bind a TreeView to a datasource?" Now, I'm attempting to create a DataTreeView by inheriting from TreeView and providing complex data-binding, but have run into many design issues. I have seen several solutions, such as the ones here:
http://msdn.microsoft.com/library/en-us/dnwinforms/html/custcntrlsamp3.asp#custcntrlsamp3_download
http://www.abderaware.com/WhitePapers/datatreeview.htm
However, the problem with all these solutions (and many other things .NET) is their exclusive focus on DataSets. I'm trying to create a more versatile control that can additionally support actual tree structures, lists of lists, or any other class.
One solution I considered - specifying a DisplayMember/ValueMember/ChildCollectionMember for the control - limits you to using a single type throughout the entire tree (or at least all types with the same display/value/children property names).
Another solution requires ITreeNode and ITreeNodeCollection interfaces to be implemented by the data source. For existing classes like the DataSet, this means either re-implementation or ITreeNode/Collection "adapter" classes. This is the best I've come up with, but I'm wondering if anybody can provide me with some more insight and/or has already done this (since a databound TreeView is one of the more sought-after controls). Or better yet, have an article that discusses how to accomplish this on the site.
What? Were you expecting something witty or funny here?

Hi all, I was wondering if anyone out there had tried using .NET objects from a pre-.NET scripting environment (I want to use Windows Script hosted JScript). I'm sure it is possible through COM interop, but can anyone tell me of an article or web page to get this running quickly and easily?
Thanks for any suggestions,
Nick

You can call a .NET component from the outside world. That's done through CCW, COM Callable wrapper, which is by the way the keyword to use to find articles on Cp, MSDN, ...
The procedure is as follows :
- write a component using C#, or whatever .NET language you can think of
- register the component to the unmanaged world using the regasm.exe cmdline. Doing so, this component looks like a standard COM component, except the fact that the InProcServer32/LocalServer32 registry key points to mscoree.dll instead (that's the CLR entry point).
- use JScript to create an instance of this object. Here is how you create COM instances :
var ExcelSheet;
ExcelApp = new ActiveXObject("Excel.Application");
ExcelSheet = new ActiveXObject("Excel.Sheet");
ExcelSheet.Application.Visible = true;
ExcelSheet.ActiveSheet.Cells(1,1).Value = "This is column A, row 1";
ExcelSheet.SaveAs("C:\\TEST.XLS");
ExcelSheet.Application.Quit();
A useful link[^] on MSDN.

Thanks, I looked around for a while but unless you know a couple of 'magic keywords' like CCW its pretty hard to search for anything containing .NET and JScript. Thanks again, there are a world of cool possibilities for this stuff
