Listboxes

I can do this in visual basic 6 but not in vb.net agghhh

Anyways how can i add what a user has typed in a textbox to a listbox. (Add it to the listindex)

And then how can i check whether what is typed in another textbox is in the listbox then if it is a form will load up

I have to do it in vb.net because its my assignment.

Also i am trying to say this,

if txtname.text = "" then
lstname.items.add(txtname.text)

else

messagebox.show("Enter Your Name")

But it shows the messagebox only when there is something inside the textbox.

Regarding the listbox i just want it search the listbox and if what they typed into the textbox is in the listbox then it will say that the item is there

try this ...

if txtname.text.length > 0 then
lstname.items.add(txtname.text)

'or if you want it to appear at the top of the listbox then
lstname.items.insert(txtname.text,0)

I know that but i want the user to type text in a text box then click a button which will read the listbox to see if it is in the listbox

I have completed it this is the code

lstuser.Items.Contains(txtusername.Text)
