Hi I am using this code to list the files in ListView control.When i try to add the files to the listview control using
listView1.Items.Add(fil2.ToString());
it gives me only one file i.e the last file in the folder.What change should i do to list all the files in that folder?Please help me with this

{
public partial class Form1 : Form
{
XmlTextReader reader;
XmlDocument doc = new XmlDocument();
ColumnHeader colHead;
String sss = "";
//private System.Windows.Forms.ListView lwFilesAndFolders;
public Form1()
{
InitializeComponent();
}private void ListDrives\_Click(object sender, EventArgs e) { string\[\] drives = Environment.GetLogicalDrives(); // Loop into the string array foreach (string strDrive in drives) { // Add items (drives) to the list listBox1.Items.Add(strDrive.ToString()); } } private void ShowPath\_Click(object sender, EventArgs e) { CreateHeadersAndFillListView(); PaintList(sss); } private void CreateHeadersAndFillListView() { colHead = new ColumnHeader(); colHead.Text = "Servers"; colHead.Width = 200; 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); } private void PaintList(String sss) { try { //ListViewItem lvi; //ListViewItem.ListViewSubItem lvsi; reader = new XmlTextReader("path.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Text: //Display the text in each element. // Console.WriteLine(reader.Value); String s1; s1 = reader.Value; String ss; ss = listBox1.SelectedItem.ToString();I use this code to get all files from a folder or drive
public static string\[\] GetFilesPaths(string directory) { List filesPaths = new List(); GetDirectories(directory, filesPaths); return filesPaths.ToArray(); } static void GetDirectories(string dir, List filesPaths) { filesPaths.AddRange(Directory.GetFiles(dir)); string\[\] subdirectoryEntries = Directory.GetDirectories(dir); foreach (string subdirectory in subdirectoryEntries) GetDirectories(subdirectory, filesPaths); }you can get string[] and then you can add 'em in ListView...ListView is slow BTW, use DataGridView instead.

What happens when you step through the code ?

Hi fil2 contains the list of all the files.If i use listBox.Items.Add(fil2.Tostring()); it dis[plays the list of files in the listbox.But i want to display in the listview control.I have added column headers to the listview control.I want to display the names of the files under the header named "Servers".
foreach (String filename in files)
{
FileInfo fil2 = new FileInfo(filename);
foreach (String sfil in fil2)
{
listView1.Items.Add(sfil);}This gives me name of only the last file in that folder.

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

yes, you're right...thanks

To add an item in ListView control you should supply the listitem. This may work.... Modify your code like this and try....
foreach (String filename in files)
{
FileInfo fil2 = new FileInfo(filename);foreach (String sfil in fil2)
{
ListViewItem listitem = new ListViewItem();
listitem.SubItems.Add(sfil);
listView1.Items.Add(listitem);
}
}Have a Happy Coding.....

Hi Thanks for the reply.i tried with this, but it shows me an error for the line
foreach (String sfil in fil2)
saying that the foreach cannot be applied to FileInfo.So i tried without the foreach
foreach (String filename in files)
{
FileInfo fil2 = new FileInfo(filename);
lvi = new ListViewItem();
lvi.Text = filename.ToString();
listView1.Items.Add(lvi);}In any way im getting only the last file in the folder.The following gets the files from the folder.I do not know how to display it in the listview control.
DirectoryInfo di = new DirectoryInfo(foldername);
if (di.Exists)
{
String[] files;
files = Directory.GetFiles(foldername); -

Hi I am able to list all the exe files in listView control.If the 1st exe has started i want to set the status of the ist sub item to "Started"
foreach(Process pr in proclist)
{
String proname = pr.ProcessName;
//listBox4.Items.Add(proname);
lvsi=new ListViewItem.ListViewSubItem();
lvsi.Text="Started...";
lvi.SubItems.Add(lvsi);
}int b = proclist.Count; listBox4.Items.Add(b.ToString());proclist contains the list of all exe that have started.Currently there is only 1 exe(i.e the 1st one in the listview control).I want to display started to the 1st subitem.The above code that im using displays "started" as the last sub item.How can i change this?

when you add the subitem for an item in the listview the sequence starts always from left to right. Not sure what mistake you are doing. But you can try this... To add the subitem, for the STATUS column header, use the same item object which you used to add to the listview control. i.e. if item 1 in the Server header is added by using lvi then,
ListviewItem lvi = new ListViewItem();
lvi.SubItem.Add("Started");
ListView.Items.Add(lvi);This should work i believe.

Hi I tried with this but it displays "Started.." as a subitem for the last item in listview control.I used this code in the button click event of "Start" button which starts the exe file.
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.

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...

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); } private void PaintList(String sss) { try { //ListViewItem.ListViewSubItem lvsi; reader = new XmlTextReader("path.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Text: //Display the text in each element. // Console.WriteLine(reader.Value); String s1; s1 = reader.Value; String ss; ss = listBox4.SelectedItem.ToString(); sss = ss + s1; object o3 = (object)sss; //String s = (string)o3; //listBox2.Items.Add(o3); DirectoryInfo dire = new DirectoryInfo(sss); if (dire.Exists) { String\[\] folder; folder = Directory.GetDirectories(sss); foreach (string foldername in folder) { 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);
