Hi,
I want to display a background text in a treeview if there is no nodes in the tree, just like the light gray text in the searchfield in the upperright corner of IE 7.
Does anybody have an idea how to achieve this?

This article[^] explains how to do it with a ListView, but the concepts are the same. The implementation make work as is, after you change the base class to TreeView though.
Take care,
Tom

Batch files are not written in C# or VB.NET, as far as I know. This means you're in the wrong forum.

The ServiceController class gets you some of the service's info, but not the startup type. For that you will need to get the Handle[^] for the service to monitor and get the startup type yourself using QueryServiceConfig[^].
pinvoke.net has signature for it[^] (see the sample at the bottom).
Be sure to Dispose/Close the handle when you are done with it. It will be cleaned up automatically, but it's better to do it yourself.
Take care,
Tom

i have a class that extends the window UIElement
class MyWindow : window{
..yada yada...
}
inside MyWindow, i use a DockPanel to Dock an instance of MyGrid:
class MyGrid : Grid{
.. yada yada ...
}
inside the grid i dynamically create a bunch of TextBox()'es that gets and sets some values of an object.
MyWindow has some overrides of KeyUp and KeyDown events that i manage, for instance i campture when CTRL-keys are pressed and other stuff
my problem is that if i change a value in one of the TextBox'es, then MyWindow looses Focus (i think) -- the KeyUp and Down events are nomore being captured 
one thing which is important, is that i have a Blur() method on MyGrid that removes the TextBox'es and other stuff whenever an object is de-selected from MyWindow
MyGrid.Blur(){
ColumnDefinitions.Clear();
RowDefinitions.Clear();
Children.Clear();
}
this method causes the docked grid to disapear, but the keyboard is still writing to the last (now not existing) TextBox()
What to do ???

This question gets asked all the time, despite the number of times that it's been answered. You use delegates to pass data between forms

You can access it directly.
myGrid.Rows[0].Cells[0]
for example.

'some error' ? Does the label of that name exist in your form ? You shouldn't have to use this in a forms app.

Is it possible to use a WebBrowser control to open an existing web page and populate the text controls on the web page from VB.NET code? NOTE: the web page could be any existing page. For example www.google.com. Browse to Google and put some search text into the text control and press the Search button.

I use this[^] tutorial in socket programming. I could build and execute it without problem.
But now I want to add it to my windows form, so my windows form can communicate. I got a bunch of errors when I add the files into my projects.
Any advice?
Thanks in advance.

You're adding a native C++ class to a .NET project? Are you using C++/CLI? What are the errors you are getting?

Hi All,
I'm having trouble docking a window which should automatically fixed to the top, right and left edges of a one half of a SplitContainer when it opens. The child window should open when I click an option from a TreeView that I'm having in the other part of the SplitContainer. Thanx in advance.

What exactly is the trouble?

You do not very clearly describe exactly what it is that you are trying to do.
If I read this correctly then it appears that what you are doing is this:
left side has a treeview with items in it.
when you click on a value in the treeview you populate the other side with a control that is populated with the data related to the value chosen in the treeview.
I also am guessing that the problem is that the user control doesn't dock in the other side of the SplitContainer.
It is up to YOU to do that. Do the same thing programmatically that you would do in the designer.
1) put control into container
2) tell the control how you want it docked.
... era does not rock if era cannot clearly explain his problem.
