Re: ListView in C# - C# Discussion Boards

okay.....

then you may try the SubItem index property, to directly specify which subitem to modify.

for example,

if you want to change the status of the first server Item, then

ServerItem1.SubItems[1].text = "Started";

Hi I tried with this.Is this right?Nothing gets displayed when the exe starts.

int g = lvi.Index;

               lvi = new ListViewItem();

               if (g == 1)
                   lvi.SubItems[1].Text = "Started..";

               listView1.Items.Add(lvi);

no this will not work. because you are creating a new lvi.

Hi Can you please tell why it adds "started.." as a sub item for last item?Why does it not display it as the sub item for the 1st item?

Not sure what's the problem....

but instead of this

foreach(Process pr in proclist)
            {
                String proname = pr.ProcessName;
                //listBox4.Items.Add(proname);
                lvsi=new ListViewItem.ListViewSubItem();
                lvsi.Text="Started...";
                lvi.SubItems.Add(lvsi);
            }

try this

foreach(Process pr in proclist)
{
String proname = pr.ProcessName;
//listBox4.Items.Add(proname);
lvi.SubItems[1].Text = "started";

}

Make it sure that you are executing this code after adding the item to the list view... otherwise you may get an exception in the blocked line.

Hi It tells that 1 is not valid argument index.

how many column headers you have???

because the subitems index always starts from 0.

can you post the entire code block of the listcontrol??? if possible...

Have a Happy Coding.....

Hi I have created 3 column headers

private void CreateHeadersAndFillListView()
       {
           colHead = new ColumnHeader();
           colHead.Text = "Servers";
           colHead.Width = 250;
           listView1.Columns.Add(colHead);

           colHead = new ColumnHeader();
           colHead.Text = "Status";
           colHead.Width = 100;
           listView1.Columns.Add(colHead);

           colHead = new ColumnHeader();
           colHead.Text = "Last accessed";
           colHead.Width = 100;
           listView1.Columns.Add(colHead);


       }

           }

Hi,
If i add subitem like the following it just gives the subitem "Started" corresponding to every item in listview.But what i require is that when the server starts it must display the subitem "Started.." to the corresponding item (server) that has started.

DirectoryInfo di = new DirectoryInfo(foldername);
                                    if (di.Exists)
                                    {
                                        String[] files;
                                        files = Directory.GetFiles(foldername,"*.exe*");

                                        foreach (String filename in files)
                                        {
                                            lvi = new ListViewItem();
                                            lvi.Text = filename;
                                            listView1.Items.Add(lvi);

                                            lvi = new ListViewItem();
                                            lvi.SubItems.Add("Started..");
                                            listView1.Items.Add(lvi);                                                                             

                                        }
                                        this.Controls.Add(listView1);

So you finally got that....!!! Hail Hurray!!!

If you want to show the status dynamically, then you need to go for threading.....

Dedicate a thread specifically for updates and things will work...

Have a Happy Coding.....

Hi I tried with the following code. It displays "Started" as a subitem for the 2nd item in listview control

lvsi = new ListViewItem.ListViewSubItem();
               lvsi.Text = "Started..";
               //lvi.SubItems.Add(lvsi);
               listView1.Items[1].SubItems.Insert(1, lvsi);

If i use

listView1.Items[0].SubItems.Insert(0, lvsi);

it displys "started " as an item and not a subitem like

Server status Last accessed
started
Server1.exe
...
....

Can you give me some suggestions

I use this code to get all files from a folder or drive

public static string[] GetFilesPaths(string directory)
{
    List<string> filesPaths = new List<string>();
    GetDirectories(directory, filesPaths);
    return filesPaths.ToArray();
}
static void GetDirectories(string dir, List<string> filesPaths)
{
    filesPaths.AddRange(Directory.GetFiles(dir));
    string[] subdirectoryEntries = Directory.GetDirectories(dir);
    foreach (string subdirectory in subdirectoryEntries)
        GetDirectories(subdirectory, filesPaths);
}</string></string></string>

you can get string[] and then you can add 'em in ListView...ListView is slow BTW, use DataGridView instead.

Just a point of curiosity. Why do you pass the List by reference? I thought that a collection can be added to without passing by reference

Hi every body
I'm Malkan
How are you?
I have small problem.
This is my code:
1- int? g;
2- g = vamTableAdapter1.SelectShomvam(textBox1.Text, textBox2.Text);
3- decimal? h = vamTableAdapter1.SelectMablkol(System.Convert.ToInt32(g));
The input of third line is Int and the output of it is Decimal?
this line(third)worked well already.But after change my database......
They are my errors
"Specified cast is not valid"
"when casting from number the value must be a number less than infinity"
But I know taht my code are true.
Plese help me
Thanks alot

Convert.ToInt32 is going to return a value that equates to infinity if g is not a number.

Your code is really crappy, please tell me you're a first year student ?

Hi All,

The problem that we are facing is that we are unable to connect the windows service through the socket running on computer A from the windows application running on computer B. The following are the steps that we have followed.

At Window Service Side running on Computer A:-

· We have created a window service and under OnStart event we have initialize the object of TCP listener through port 8001.

· Start the TCP listener.

· Made a thread for WaitingForClient and start this thread so that it always lies in listen mode for accept the socket from Computer B.

· In the method WaitingForClient we have accepted the socket and start another thread for read this socket.

At Window Application running on Computer B:-

Made a socket that has AddressFamily InterNetwork, SocketType is stream and ProtocolType is TCP.
Made the object of IPEndPoint by initialize it through IP address of Computer A and Port 8001.

When we connecting this socket to the Computer A through IPEndPoint, it does not connect and throws the exception of connection timeout.

Plese Help............

Thanks and Regards,
Lalit Narayan

Does it work if you run the client and service on the same machine? If so, it's probably a firewall blocking your port.
