Fill Listbox

Id like to fill a listbox (BC++ 6) with the numbers 0 to n;

Its a graphical user interface and i cant seem to get it to work.

From what i figured out: ->Items->Add(i) adds a string i to the listbox but it doesnt wanna add more then 1.

I tried: something like this (pseudo code)

for(i=0; i <= n; i++)
Items->Add(i)

now im wondering how i can extend it to make it add more then jst one number.

ANyone have any clues??

Its a wrapper

This doesn't seem to be Win32 API, what is it? A wrapper?

I think its a wrapper, but just tell me
how do i increment the listbox position so i can write multiple lines.

Been ages since I used Borland to create a Win app.. wish I could help, but all is forgotten. I got an old book lying around though and will browse through it to see if I can see the solution.

(I think they call it the Visual Component Library)

Just quickly, you are only trying to add STRINGS right? The listbox only seems to like strings so your logic should work.

Code:

---

Listing->Items->Add("Item 1");
Listing->Items->Add("Item 2");
Listing->Items->Add("Item 3");
Listing->Items->Add("Item 4");

Listing->Items->Insert(4, "Item 5");

---

??

If you are trying to add #'s perhaps there is a way to convert it to a string first?

Code:

---

pseudocode
for(int i = 0; i < n; i++)
Listing->Items->Add(convertToString(i)); // Pseudocode not actual code.

---

For some reason the increment doesnt work, as it only adds one line. Namely where i<=n.
Iff i add them manually like add("a"); add("b") it works fine. But if i use the itterator to add each time it doesnt work.

Is there something to increment the position in a listbox or something similar.
Im really stuck here.

The std cout function works fine like that. But this whole VCL is doing my head in.

so:

Code:

---

for(int i = 0; i < 5; i++)
  Listing->Items->Add("a");

---

So when you do the above in your code it isn't adding 5 a's to your listbox?

Also, there appears to be an insert function:

Insert(param1, param2);
Where
param1 = position into the listbox where 0 = first item, 1 = second, etc..
param2 = string to add.

Code:

---

for(int i = 0; i < 5; i++)
 Listing->Items->Insert(i, "a");

---

It does work???

for(int i = 0; i < teller; i++)
this->ListBox1->Items->Add(i);

adds the number from 0 to teller

still dunno where i went wrong.

Tnx a llot

yep, no problem.

As for your original problem the only thing I can think of is possibly a pesky semicolon at the end of your loop statement.

Ex:

Code:

---

for(int i = 0; i < 5; i++); <---- Would cause an empty loop to execute 5 times.
  this->ListBox1->Items->Add(i); <---- After the loop ends this statement is only executed once.
