Code: When an item isn't selected in a listbox.

[MaKiT]

I need an 'If then else' statement so if text in a listbox is not selected then a message pops up saying 'Please select an item'.

I can do the message bit but I dont know what to put after 'If'.

Any expert help?

Maybe Listbox1.SelCount > 0 ???

I just figured it out, funily enough by looking at a visual basic app.
It was:

If listbox1.itemIndex = -1 then
showmessage('Select a File first')
else
...

Thanks for replying though

That's why I suggested SelCount property, 'cause you could then do:

if ListBox1.SelCount > 0 then
begin
    for n := 0 to ListBox1.Count - 1 do
        if ListBox1.Selected[n] then
            ProcessFile(ListBox1.Items[n]);
end
else
    showmessage('Hey dude, select some file!!!');

only to make it multi-file aware.
