Simple ListBox question

[stylonurus]

After I add a line of text into a ListBox, I would like to make that line visible. That is I would like to see the last 4 lines. The user can scroll up but when a new line is added I want to insert that that line at the bottom and have it displayed as well. Can anybody please help me.

Also, I am somewhat new to Borland C++ Builder 6. (Several months on this C++ application) Where is the best place to get questions like this answered? This is the first site I have left a message on. Perhaps its here. Thanks

Rick

OK, let me see if I understand you correctly. First, you want to add an item to the end of a list box. Make sure your ListBox Sorted property is set to false. You can add an item via:

MyListBox->Items->("Something added");

Next you want to make sure the list box displays the last item. Try something like:

int ItmInt = MyListBox->Items->Count; // The number of items in list box
if (ItmInt > 0) // There is something in the list box
{
    MyListBox->Selected[ItmInt]; // Last item selected
}

See if this is close to what you want. Also, for further reading try:

As far where to go to get answers, you found a great place here. ;-)

A Simple way to do what you want is this:

// add a string to the listbox
MyListBox->Items->Add(MyAnsiString);
// set the ItemIndex to the last string added
MyListBox->ItemIndex = MyListBox->Count;

James,
Thanks so much for your response. I'm going to try it but I also have found something a bit different that works.

MyListBox->ItemIndex = LineCount;

where LineCount has the index value of the last line in the List Box.

Take care
