Yes.

Create your panel, with the rows and columns you want.
Add a label control to each, and set its Dock property to Fill.
Set its TextAlign property to MiddleCenter.
Set each label Click event to the same click handler.
Make your click event look like this:
private void label_Click(object sender, EventArgs e)
{
if (sender is Label)
{
Label lab = sender as Label;
if (lab.BackColor == Color.Red)
{
lab.BackColor = Color.AntiqueWhite;
lab.Text = "Hello";
}
else
{
lab.BackColor = Color.Red;
lab.Text = "Goodbye";
}
}
}

We want to open an FTP link in remote desktop machine?
after opening the link we need file information on the FTP link.
How would that happen?
Any help would be appreciated........
Thanks

do you need to get some files from the remote machine ? if so you could directly put ftp commands in a file and you can run it like,
open machine name
username
password
get a.txt
bye
why are you trying to open a link in the relate machine

Thanks,
we have requirement to open an FTP link which can only be run in remote machines(any port setting is there perhaps).

what do you mean by opening a FTP link in remote machine ?

We have to access a file and that file is on a ftp location and that ftp location can only be accessed by remotely connected server.So the steps that we need to take is as :
1-Remote connection to a server
2-after RMC connect to ftp.
3-check the modified date of a file on ftp location.
I think It calrifies all your doubts.
Thanks,

As far as I know you can keep a binary or a script on a remote machine which can access the server and ftp the new file to the remote machine.

Hi,
I'm trying to debug a smallish application which crashes approximately every 10 days with an out of memory exception. Specifically, i've established that the problem lies within a single thread, and I suspect I know which object is causing the problem, but I need to find out when copies of this object are being added and removed from the memory.
If this is not possible, could I perhaps have some general pointers as to when an object is generally added and removed from memory? I realise of course that what is likely happening isn't the application running out of physical memory, but running out of address space, but understanding the problem is getting me no closer to a solution!
Any help would be appreciated,
Thanks,
Nil

Hi,
proper use of try-catch blocks should pinpoint the problem.
I know of three ways to get an OOM Exception:
1.
the most surprising one: some methods throw OOM on bad inputs, most notoriously: Image.FromFile().
2.
you are really running out of memory; typically that means you are preventing objects from being collected. You can watch your app grow, roughly through Task Manager; more correctly by incorporating a display of Environment.WorkingSet in your app.
One way of keeping objects around is by storing references to lots of, or all, objects you create; maybe for debugging, for statistical information, as a cache, whatever. If so, consider the WeakReference class.
3.
you have objects larger than 80KB; those get allocated on the "large-object-heap", which never gets compacted, and hence could become fragmented, resulting in an OOM even when lots of free memory is still around (but each chunk is smaller than the size needed).
Remember: lots of collections (ArrayList, List< T>, etc) are stored as arrays, and such arrays get doubled in size and copied each time their capacity gets exceeded.
IMO you can't reliably design a long running .NET app if you need large objects, unless you:
- either make them all the same size;
- or perform the entire memory management for large objects yourself.
Both of which may be tedious. A third possibility is making your app restart periodically all by itself.

AFAIK the fragmentation issue that exists in the .NET CLR is not fundamentally present in Windows itself, so .NET apps have one reason not to be long-lived that Windows apps don't have.
MS could alleviate the problem by adding a CompactLargeObjectHeap() method to the GC class but I don't expect them to do so any time soon.

Can you change the code? If so, just put some logging in the constructor(s) and the finalizer.
In terms of when an object gets added and removed from memory, in .NET (for reference types) it gets allocated when you new up a type prior to the constructor call. It gets removed at some indeterminate point in the future when its no longer being used by the .NET garbage collector.

Hi all,
I am trying to manage group policies programaticaly, using C#. I have searched through google from last 2 days and find nothing on it. In one forum I have found that I need to add "GPO Admin 1.0 Type Library" from COM reference into my project. But in Visual Studio 2008 (.NET framework 3.5) does not contain it.
So, right now I do not know whether I can do that or not.
All kind of relative suggestions are welcome. Thanks.

I've done some programming in C# when it comes to user groups and policys (but probably not the way that you're about to do..). For the user group part I used some netapi.dll methods with p/Invoke. For the policy part maybe you could check the System.Security namespace? It's been awhile since I worked with these things so you have to excuse this kinda vague answer :/ Good luck!

Hi Calla,
Thanks for the reply. I'll surely try the System.Security namspace.
Yesterday, I have found something interesting in MSDN. They are using scripts (JScript, VBScript or Shell Script) for managing Group Policies. But I dont know even 'S' of scripting langauges. Lets see how much I can progress in that foeld with C#.
Bye.

hi all, i've encountered some mistake with serial port developement.
I use the compact framework 2.0 with visual studio 2008 pro.
I've developped a simple application which do a serialprt.open() on the port COM1.
(i've tested with COM2, COM3 and COM4 too but same exception).
When I deploy the project with visual studio on my Windows Embedded CE 6.0 device all works fine.
But when i reboot the panel pc (an AFL-07A-LX) and when i try to open a COM port I have an exception :
Exception : IOException
Inner Exception : null
Stack Trace :
at System.IO.Port.SerialStream.WinIOError()
at System.IO.Port.SerialStream.CheckResult()
at System.IO.Port.SerialStream.setBufferSizes()
at System.IO.Port.SerialStream.Open()
I'm searching for the solution from 2 days and i've found nothing at all 
N.B : i'm french so don't take care to my bad english.

Hi,
How i can send mail to more that one person,
i've looked all over the internet and find only the option to add the Bcc (Blind carbon-copy).
Is there any other option to do so, like at the "TO"?
Thanks,
Tamir

The 'to' in some mail programs, just adds to the CC, which is like the BCC, except everyone can see who you mailed to.

Hi,
when using the MailMessage class, the properties To, Cc, and Bcc are MailAddressCollections.

Forgive me if this is too obvious, but have you tried simply semi-colon seperating the addresses you want to send to?
I.e, if you want to send an email to three people the string passed into the "TO" field would be something like "john@something.com ; bill@something.com ; ted@something.com".
Is that what you mean?

Ofcource...
and i received this error:
The specified string is not in the form required for an e-mail address

I run a c# application which returns results in the format of the following text:
Is this example below, I would like to return the text "SizeStoredInPagingFiles: 4476456"
I always need to get the last text such as the above in this sample.
"Microsoft (R) Windows Script Host Version 5.6\r\nCopyright (C) Microsoft Corporation 1996-2001. All rights reserved.\r\n\r\n-----------------------------------\r\nWin32_OperatingSystem instance\r\n-----------------------------------\r\nSizeStoredInPagingFiles: 4476456\r\n"
"Microsoft (R) Windows Script Host Version 5.6\r\nCopyright (C) Microsoft Corporation 1996-2001. All rights reserved.\r\n\r\n-----------------------------------\r\nWin32_OperatingSystem instance\r\n-----------------------------------\r\nversiontext : 2\r\n"
In the above sample I would like to return "versiontext : 2"
How do I do this please?
