That is exactly what happened. Maybe should have posted that in the beginners thread.

I felt secure because boost advertises itself as being "mostly headers" and I only skimmed across the list of binaries to be linked. I missed "libboost_serialization.so".

Most aren't at all intimidating and pretty much give you step-by-step instructions in the associated reference stuff.

I should give implementing diffie-hellman key exchange a go.

[Skyrunner]

Oh, I didn't look at the references section at all. haha

Looks like an interesting course.

Anyone else focusing their study on Ruby (and more specifically, the Ruby on Rails framework)?

Coming off of an intermediate knowledge of Python and some formal training in C++.

[Parsely]

Could someone help me out with some VB?

Code: [Select]

    Private Sub btnReport_Click(sender As Object, e As EventArgs) Handles btnReport.Click

        lblReport.Text = "Finalists: "

        For Each item As String In listFinalists.Items
            lblReport.Text = "Finalists: " & listFinalists.Items.ToString    'this doesn't work
        Next

    End Sub^^The offending stub.

I just want to move all the items from the listbox to the label beneath the "Finalists: " string, so it looks something like this:

Finalists:
Chief John Anderton
Billy Mays
Butthole Surfer
etc.

I'm not a VB guy except for a little VB script, but if you have that

Code: [Select]

For Each item As String In listFinalists.Items
Isn't "item As String" your string and "listFinalists.Items" the collection?

It wouldn't make sense to "ToString" the listFinalists.Items, when just "item" is your variable. Try :-

Code: [Select]

lblReport.Text = "Finalists: " & item
It's similar to for (int item =0; item < max_item; item ++) in c++

[Parsely]

That will only grab the first item on the list.

[Reelya]

There's your problem, you don't understand what's going on. "item" is the loop variable that's being used to extract the data. the name "item" is generic.

This is an example from MSDN of corrent usage:

Code: [Select]

For Each item As String In lst
    Debug.Write(item & " ")
Next
So, "item" is indeed the loop variable that's being set to the string, and is what you need to use inside the loop

[i2amroy]

Really nowdays in C++ you would just write:

Code: [Select]

for (auto &i : items) {and iterate through them directly unless you had a valid reason for index shenanigans.

[Reelya]

I whacked up the standard c for loop for educational purposes. Using the latest fancy gizmo that only works in one language would not have helped to illustrate the concept, but I can have a reasonable assumption that someone's come across the standard for loop in some language or editor.

but if you want to iterate over a specific range and that doesn't exactly coincide with any data structure you're still going to need to specify start and stop conditions. What if index 0 is reserved for a null condition and you don't want to actually process that index?

[Parsely]

There's your problem, you don't understand what's going on.

Spoiler (click to show/hide)

It only outputs the first item on the list, Reelya.

[Reelya]

Code: [Select]

        lblReport.Text = "Finalists: "

        For Each item As String In listFinalists.Items
            lblReport.Text = "Finalists: " & item   
        Next

is overwriting the entire lblReport.Text each time. There's no way it will ever hold more than 1 item that way. It should be something like:

Code: [Select]

        lblReport.Text = "Finalists: "

        For Each item As String In listFinalists.Items
            lblReport.Text = lblReport.Text & ", " & item 
        Next


[Parsely]

It looks like I overwrote the lblreport.text with the string "finalists" and one item each time through the loop.

FTFY

try appending to the lblreport.text by doing :

lblreport.text = lblreport.text & " " & item.

This works! Thanks for the help Reelya.
