Hello again :

How do I specify which item in a listbox I want selected
The listbox is already populated, and if the user types in a value into a textbox, I want that value to be highlighted in the listbox

Thanks

Set the listbox's 'SelectedIndex' or 'SelectedItem' property.
 
Yes, I figured that, but I'm looking for specific syntax to force a listbox.selecteditem to equal a texbox
Thanks

This is kicking,

Some (maybe what longer) time ago I got every time a messages from
Herfried.

"Better is findstringexact"

But very much "better" is

\\\
me.listbox1.SelectedIndex = Me.ListBox1.FindStringexact(Me.TextBox1.Text)
///

I would not have written this if I had not seen that findstringexact

I used 'FindString' because it allows to search for parts of the string.

If there are items...

Cor
Corina
Corinna
Corrina
Corrinna

.... typing "Corr" into the textbox will select "Corrina".
