In my spare time, I'm trying my hand with Visual C++, and what I want to do is have a linked list of Nodes containing string and int variables. I would then like a ListBox in the form to display the data in the nodes.

Could somebody be so kind as to help me out? I'm brand new to Visual and still trying to find my way around.

We're here to help. Write some code and post here if you're having any problems. Be sure to read the "How to post a question" and "Forum Rules" thread.

Sigh, I suppose I should try and fail first :p

I guess what I really want to ask is whether there is a built in function to do it. If not I can probably work out a function to do it.

On top of that, what kind of variables can be assigned as text in a text box?

For example, I tried to do this:

(Toggle Plain Text)

int Item = 4500;
txtItem->Text = 4500;

And got an error about type mismatches, though it will work with strings.

Also, how can I access form items from a file other than Form.h? For instance, in my main code file, I went:

(Toggle Plain Text)

Form1::MyTextBox->Text = "something";

but I can't use the -> operator, or the :: operator.

Dam' right, we ain't your nannies. Incidentally, there is a current thread regarding a linked list. Go on over and read the forum's rules/FAQ, the "How to Post..." thread, and so forth. You will discover that you are supposed to invest a little effort in looking around before you jump all over our good natures and take our freebies.

Actually, I did search, and found nothing pertaining to my original question of using Linked Lists combined with Visual List Boxes.

Pretty obvious, Text is of type string, so it will not accept an integer.

(Toggle Plain Text)

txtItem->Text = "4500".

Convert it back when needed.

Where have you declared Form1?

So, you're looking for a 'Visual Linked List Box' ? :p

BTW what the heck are "Visual List Boxes", and if you're using .NET wouldn't it nice to say so?

Twilight · Apr 19th, 2006, 1:54 AM

I'd love to tell you, but to be honest I'm not really sure I am. It would seem probable I'm using .net though. I just downloaded Visual Studio Express Edition, and starting fiddling with forms and such.

As for a Visual List Box, I suppose it's fairly redundant, as it's just a ListBox.

VStudio did it for me (I think).

Right above where I tried that, I had:

(Toggle Plain Text)

Application::Run(gcnew Form1());

And I have a complete Form.h and such that Studio made for me.

If you want to work with normal C++ you can do so, like this.

I don't know anything of C++ .NET

Why not use the built in array types? The ArrayList would work fine. All you need to do is create an object that has an int and a string and then load them into the arraylist, cast them back to the class when you wanna use them.
