Hi All,
I am looking for some sample code for printing the content of the a tree view control. I was just curious if someone had any ideas.
Thanks

I may have the wrong idea, but why not just make a richtextbox, have it paste in the contents of each node, and on each node level tab it?

Hi James,
That would do the trick. The only thing is that I need the treeview for some user interaction but I could use the rtb as an intermediate step.
Thanks for your feedback.

I would like to be able to mark a webmethod as obsolete by applying the obsolete attr to the method. What i really want out of this is for the description of the webmethod to show that this is a deprecated method and not to use it. Using this with non webmethods works just fine.... any tricks?

And what is a webmethod?
I have never heard of such thing...

Check out MSDN Library on "ControlStyles" flag and "SupportsTransparentBackColor" and "Opaque" style. By using these styles and providing a background color with an "alpha" value you can make it transparent. All you need is to play with the alpha level of the System.Drawing.Color structure.

you should just use a message from form2.and then you will see your form1 can recognize that.if not ,try again.
Always do you best,what you plant you will harvest

I want to create an Windows Service which displays notifynicon on the taskbar with contextmenu. If user choose "show management panel" from the context menu a simple Windows Form appears and user can modify service behaviour form it.
So what is the problem?
1.
I created simple WIndows Service (local system whith access to the desktop) and added NotifyIcon and contextmenu components to it. When I rum my service notify icon appears on the taskbar and everything seems to work properly... but when I right-click on the icon context menu does not appear. What's more - I added double-click event for the NotifyIcon and It also does not work properly - Message box does no appear.
The same components in simple Windows Form Application work well. So I thought that I must add windows form to the service to make it work.
2.
Maybe, but Application.Run(new MainForm()); needs to be invoked in different thread because service waits for the WIndow to be closed - there must be much more simple way to do it.
I'm new to Windows Services, coud you help me with my problem?

1. Services can run without an interactive (logged-in) user, so services which allow interaction need to be configured as such. So, open the Services control applet, and goto the properties of your service and ensure that "Allow service to interact with the desktop" is selected.
2. You should read up on remoting and communicate with your service in this way.
|

|
|
|
Interaction with desktop is allowed.

I know that windows service shoudn't have user interface.
Do you think that using .NET Remoting to comunicate with service is better than include management form inside service?
But the question was why my context menu isn't working. And why events such as double-click aren't catched.
And what about creating window in another thread inside service?

Maybe the reason why it isn't working is that Windows Service does not have classic Message Loop as Windows Applications have.
I currently solved my problem in, let's say - no professional way.
I created Window in a different thread:
public partial class Server : ServiceBase
{
MainForm window;
Thread thread;
public Server()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
thread = new Thread(new ThreadStart(WindowFunction));
thread.Start();
}
protected override void OnStop()
{
}
private void WindowFunction()
{
Application.Run(window = new MainForm());
}
}
but is it really the best solution?

Like others have said before, the usual way to do something like this is to have the service running without desktop access and to have a controller-type application that's communicating with the service, for example by using remoting.
