[2005] Displaying a string

Hello,

I've recently completed a little bit of code and want to see it displayed in a message box. This I can do, the problem comes when it is displayed, it will read:

-1

This is my code:

Code:

---

HideWelcomeScreen()
        HideAddItems()
        lst_results.Visible = True
        lst_results.Items.Clear()
        counter_search = 0
        letter = Len(txt_search.Text)

        Do While counter_search < letter
            tempresult = tempresult + lst_dictionary.Items.Item(1)
            tempresult.Remove(tempresult.Length, (tempresult.Length - letter))
            counter_search += 1
        Loop

        MsgBox(tempresult, MsgBoxStyle.OkOnly, tempresult)

---

The error says "Index and count must refer to a location within the string."
This is pointing to here:

tempresult.Remove(tempresult.Length, (tempresult.Length - letter))

What can I do here?

you're asking it to remove letters from the string, starting at the end of the string

I want to remove them from the end, and go backwards ... I thought that was what it did ... :S

try it this way

vb Code:

tempresult.Remove((tempresult.Length - letter), tempresult.Length - (tempresult.Length - letter))

Code:

---

HideWelcomeScreen()
        HideAddItems()
        lst_results.Visible = True
        lst_results.Items.Clear()
        counter_search = 0
        letter = Len(txt_search.Text)

        Do While counter_search < (lst_dictionary.Items.Count)
            tempresult = lst_dictionary.Items.Item(counter_search)
            tempresult.Remove((tempresult.Length - letter), tempresult.Length - (tempresult.Length - letter))
            If tempresult = txt_search.Text Then
                lst_results.Items.Add(tempresult)
            End If
            counter_search += 1
        Loop

---

That code seems to work perfectly, until you enter 3 characters, then I get the error message that "StartIndex cannot be less than zero." This is here again:

tempresult.Remove((tempresult.Length - letter), tempresult.Length - (tempresult.Length - letter))

If you want me to, I can zip the whole file up and you guys can have a look yourselves.


I still have not managed to get a result in the lst_result list box.

Okay, I think I've nearly completed this.

The last part is to trim the end of the string: tempresult

Basically, if a person enters "4" then it searches the first item on the listbox. That is 404 error. I want it to trim the "04 error" off of the "404 error" so only 4 is left. How can I do this?

I've tried this code:

Code:

---

tempresult.Remove((tempresult.Length), tempresult.Length - (tempresult.Length - letter))

---

And it doesn't work.

Any ideas?

it works this way

vb Code:

.remove(startIndex, length)

its zero based so startIndex cannot be less than zero & length + startIndex + 1 cannot be greater than the length of the string

So what should I place in there?

I've tried a few variations of what I said didn't work, and still can't get it to work ...
