Hi,

I haven't used ImageList class yet, but I just read some of the documentation, and that helps.
An ImageList has a Images property, which is a collection, meaning you can get one of its members by using an index, you can clear the collection by calling Clear(), and adding to the collection by calling Add(). So this would be my first attempt:

// having a listview that may or may not have some images in its list already,
// and having another list of images, we copy the latter in the former:
foreach(Image image in ImageList1) {
    myListView.Images.Add(image);
}

Hi,

as I already told you, you can use an index or an enumerator.
Here is an index example:
myListView2.Images.Add(myListView1.Images[0]); // "copy" first image

IndexOf returns wrong value if the string to search for contains characters from the Latin Extended-C range

don't take it personal. Seems like all articles are unreachable right now...

Since the string "qwerty" does not contain a small letter l with a double bar (\u2c61) one would expect that when the code below is executed, both p and q would get the value -1. However, the second call to IndexOf does in fact return 0 instead of -1. After some further experimenting I found that this happens with several characters from Latin Extended-C (probably all of them) and that the return value is the same as the value of the second argument, i.e. the starting position for the search.

Is this a known bug? And can it be circumvented other than by writing my own search method?

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int p = "qwerty".IndexOf('\u2c61', 0);
System.Console.WriteLine(p);

int q = "qwerty".IndexOf("\u2c61", 0);
System.Console.WriteLine(q);

System.Console.ReadKey();
}
}
}
