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);
}
}

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 mrithula....
I have personally checked the below code and its working properly in my machine....
DirectoryInfo di = new DirectoryInfo(fbd.SelectedPath);
if (di.Exists)
{
String[] files;
files = Directory.GetFiles(fbd.SelectedPath);
foreach (string file in files)
{
ListViewItem lvi = new ListViewItem();
lvi.Text = file;
lvi.ImageIndex = 0;
listView1.Items.Add(lvi);
}
}
If it shows any error let me know....
Have a Happy Coding.....

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;
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;
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...

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...

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..";
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 ?
