I don't know why pictures aren't shown in listview.. i would like to add them like thumbnails..or small icons..so when i will click on them they will resize in picturebox.. Here is code for adding to listview which isn't working.
private void Form1_Load(object sender, EventArgs e)
{
DirectoryInfo dir = new DirectoryInfo(@"d:\\feri\\ičr\\galerija\\galerija\\galerija");
foreach (FileInfo file in dir.GetFiles())
{
try
{
this.imageList1.Images.Add(Image.FromFile(file.FullName));
}
catch
{
Console.WriteLine("This is not an image file");
}
}
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++)
{
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
}
}

Speaking purely from memory (can't get to VS to test at the moment) resizing an ImageList clears it. Your code resizes the ImageList after loading the images.
Try moving the resize to be before loading the images.

Now its duplicating images in listview...how could everytime someone adds image to it..that content before would be erased and new images would be added then..
private void btn_browse_Click()
{
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(60, 60);
this.listView1.LargeImageList = this.imageList1;
try
{
OpenFileDialog open = new OpenFileDialog();
open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
if (open.ShowDialog() == DialogResult.OK)
{
picture.Image = new Bitmap(open.FileName);
this.imageList1.Images.Add(Image.FromFile(open.FileName));
}
}
catch (Exception)
{
throw new ApplicationException("Failed loading image");
}
for (int j = 0; j < this.imageList1.Images.Count; j++)
{
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
}
}

It would be nice if the image collection had a method to clear itself.

Gosh, wouldn't that be a good idea. You'd have thought Microsoft would have thought of that, wouldn't you?

And how this method for cleaning would be?

private void btn_browse_Click()
{
imageList1.Clear();
}
Unless they are likely to be changed somewhere else in your application, you would be better off setting the following three properties in the designer.
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(60, 60);
this.listView1.LargeImageList = this.imageList1;
You should be OK now. Good Luck!

OK. A clue, and the only one I'll give. ListView has two properties that begin with Selected read the documentation for them.

I am working in Microsoft Visual Studio 2008 using C#. I populated my webpage from a database which was SQL Server 2005. On the webform that will be displayed to the users, I want to display a textbox when they click the checkbox, and if they don't click the checkbox I don't want the textbox to be displayed. How do I go about this?? Thank you!!

We have an ASP.NET forum.
You would do this with javascript, which means it's more of a general web dev question.

this can be done with javascript
use,
function ChkFunc()
{
var chk = document.getElementById("<%=CheckBox1.ClientID%>");
var txtbox = document.getElementById("<%=TextBox1.ClientID%>");
if (chk.checked) {
txtbox.style.display = "block";
}
else {
txtbox.style.display = "none";
}
return;
}
in code behind,use
CheckBox1.Attributes.Add("onClick", "return ChkFunc();");
to make the textbox invisible on load, cal this javascript function in page load as well
dont use TextBox1.Visible=false in page load,then this script gives error.
Hope it helps u.

What you seem to be doing is different, to say the least. As such I have no answer for you.
Whilst your question is clear and understandable, is there any chance that you can broaden your description to include the aim of the application, or why the user would be typing code into a text box?

In simple words, you cant. Learn how to use regular expression if you really need this type of task.

Of course you can; I have a small program that takes one method from a textbox, compiles and executes it. It is based on CSharpCodeProvider class. It isn't beginner's stuff though.
IIRC there has been a CP article on the subject, several years ago.
