hi
i have this code:
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (e.Value != null)
{
string l_value = e.Value.ToString();
char[] l_array = l_value.ToCharArray();
Array.Reverse(l_array);
e.Value = new string(l_array);
}
}
it reverse all of the datagridview
i need only column 2 that be reverse
how to change this code ?
thanks in advance

This because you are doing it in a function that would be called for every cell and hence the reversal on all values for all columns

Hi,
I want to display(on a Form) a 32bit bitmap with Alpha channel transparency, so thet the transparency is honoured.
I have tried a Picture control but it ignores the Alpha channel.
Any ideas?
Thanks - John

What format is the image? As far as I'm aware a bitmap doesn't support the alpha channel in Windows, but you would rather manage it using a chroma key (that's where you choose one colour as being transparent). If it is a bitmap, then you might want to try out the code sample here[^]
If you are using a PNG (for instance), then just set the appropriate PixelFormat, i.e. PixelFormat.Format32bppArgb;

Image.PixelFormat
Has no Set method it can only be read.

Just FYI, 32bit BMP is almost universally unsupported. Even by image manipulation programs.

Yeh, I see what you mean.
You would think by now that there would be a standard way of handling transparency, but ther isn't. its all over the place, Alpha channels, transparency masks of every posible value ever known, what a can of worms it is.

Transparency is a lot easier in WPF than in Windows Forms, would it be possible to convert the program to WPF?

I'm glad to see there are optimists still afloat ! 
imho, using PNG's with transparency has become a standard: they work in .NET, they work on the web.

Since when? Bitmaps (BMP) have supported the alpha channel for probably close to a decade or more.

Note the careful use of Windows here - it's not the problem with Bitmaps, it's a problem with Windows.

One way to do this is to use WMI, which involves adding a reference to System.Management. This is what your code might look like:
public void StartRemoteProcess(string address, string processName, string userName, string password)
{
object[] processes = { processName };
ConnectionOptions connection = new ConnectionOptions{ Username = userName, Password = password };
ManagementScope scope = new ManagementScope(string.Format(@"\\{0}\root\cimv2", address), connection);
using (ManagementClass mc = new ManagementClass(scope, new ManagementPath("Win32_Process"),
new ObjectGetOptions()))
{
mc.InvokeMethod("Create", processes);
}
}

You cannot launch an interactive process on a remote machine. This is for security reasons. Think about it.
The process will launch, IF you have admin rights to the target machine, but the user on the remote machine will not be able to see or use it.

+5 for the assumption of guilt, which doesn't waste the time it would take to examine the facts, or require ridiculous ceremonies like trial-by-jury, or absurd philosophies like "presumption of innocence."

So, Ashish-ji, given that your own Skype, when on-line, can show you the status of other Skype users you have added to your contacts: whether they are on-line, have call-forwarding on, etc.
And, you also have ability to send SMS messages from Skype (although this is something I haven't tried yet, and am not familiar with exactly what notifications, if any, are produced at the receiving end).
What is your reason for wanting the ability to (I assume) make some remote machine on-line on Skype ?
Is this on a private network, or across the internet in general ?
thanks, Bill

Make use of the FileIOPermissions[^] class.
FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, filename);
if(!SecurityManager.IsGranted(writePermission))
{
}
