No, it's not urgent. And you could answer questions like this far faster by doing Google searches[^].

I searched but all what I found
List<Control> TotalControles = new List<Control>();
foreach (Control c in this.Controls)
{
TotalControles.Add(c);
}
How I change this.Controls to forgroundwindow.Controls
thanks in advance

Sorry, pasted a response to a different question. Looks like you figured it out.

Hi all,
using online converters, the C# snippet
{
this.listView.Items.Add(new ListViewItem(dc.Line)
{<pre>
SubItems = {dc.Sign},
Tag = (object) dc
});
gets converted to
Me.listView.Items.Add(New ListViewItem(dc.Line) With { _
Key .SubItems = {dc.Sign}, _
Key .Tag = DirectCast(dc, Object) _
})
Ok, it's obvious that "Key" results in a Syntax Error in VB (amazing why all the converters I tried still put it). But after removing this, I have another error saying "The property 'SubItems' is ReadOnly". Also, IntelliSense doesn't give it as an option in VB, while it does in C#...
My question now: Would it be possible that the property isn't ReadOnly in C#, while it is in VB? Or has it been converted errorous?
Thank you in advance,
Mick

Converters are not perfect, some are better than others and I find the online ones to be the worst.
Why? Because the best converters will compile the code first, get down to MSIL and then convert back up to whatever you want. Online converters typically don't take compiled code so they attempt to do conversions with text replacements. The one you found isn't bad, but it made up the Key part somewhere, your conversion should be:
Me.listView.Items.Add(New ListViewItem(dc.Line) With { _
.SubItems = dc.Sign _
.Tag = dc _
})
(The original code the scoping around dc.Sign is unnecessary as well as casting dc to object).
So if you change it, I'm sure you'll see SubItems come back up in Intellisense, as well as Tag. Key is not a property of ListViewItem so that's why nothing comes up in Intellisense.

Hi Ron,
thank you for your answer. It's funny, but during my own attempts for a working solution I had put it just that way... and of course I'm aware of what you wrote about converters.
Unfortunately there's still something wrong, the error message stays ("The property 'SubItems' is ReadOnly."). And by just opening a new Sub which contains the line
Dim mylv As ListViewItem = New ListViewItem(dc.Line) With {.s...."you can see that Intellisense doesn't show "SubItems" then.
Do you have any further hints? I was afraid that the curly brackets (".Subitems = {dc.Sign}") have to be converted in a different way – but I had no clue what C# uses them for...

Try SubItems.Add(dc.Line).
The collection is read-only (same in C#, so I'm not sure how they are getting away with it in the original code). You can't assign something directly to it, so it should not work in the C# code either.
In C#, the brackets are scoping characters, and in the code you posted, unnecessary for anything.

 Ok, so I don't worry too much about the fact that I don't understand some of it
Thank you, anyway!

Incorrect. In this context the brackets designate a list initialiser[^]. This works because list initialisers in C# compile to repeated calls to Add, not an assignment. If that's not the case in VB then the questioner will have to call SubItems.Add directly.

Thanks, I never used them, I guess for good reason, they are also scoping tokens so I'm not completely incorrect but I forgot about using them that way to initialize a list.

List initialisers are actually really nice, particularly in writing unit tests or setting up in-memory test data.
Yes, they can be used for scoping, but only when they surround entire statements. That's rarely useful as what you'd want to use as scope regions are usually already in a block (e.g. if, foreach etc). I think case statement groups are the only place I've found that capability useful.

Hello:
it does not help because I need how I detect the object(like icon on desktop or menu etc...)
my problem how I know if mouse hover on object.
because I need to snapshot the object.
I hope you understand me.

Many objects have Mouse events - one of them is 'MouseHover'.

hi,
in my appli i need to read data thuogh serialport in two different times.
1) when i write data to handheld system through serialport ,that sholud send a success signal
2)To read some other data from serialport.
for the first one, i wrote the code for receiving success data, in esrialportdatareceived event.
then for 2) where can i write the code of reading. if i write in that event everytime success data is showing as output.

You need some method to discriminate between the two pieces of data. If the device is sending the exact same string of data every time, you can check for that and have a reasonably good idea where it came from. If not, well, then you're going to have to come up with some kind of protocol, like "framing" data, that your external devices are going to need to use to identify themselves as the source.
Or, put each device on it's own serial port.

Hello
Can anyone help me How grab all text from active window c#.
|
|
|
|

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Which "active window"? What environment? These and other questions help us to answer...

hello my friends
1-active window like (Browser,Notepad)
2-environment like windows(xp,7,..)
thanks

I think this may be useful: [^].

This question needs clarification.
1. by active window are you referring to the current active window of any Application ... not just your own Application ?
2. by "text from active window" are your referring to the Title of the Window a shown in the TitleBar of the Application ? Or, are you referring to actual Text in a Control in an Application Window, like a TextBox ?
The more detailed your question is ... the more you describe the context of what you are asking about ... the greater the chance you can receive useful responses.
