Try this:
ddlFullTime.Items.Add(New System.Web.UI.WebControls.ListItem("Now", dtNow.ToShortTimeString))
dtMod =  DateTime.Now.AddMinutes(15 - (DateTime.Now.AddMinutes(15).Minute Mod 15))
Dim target As DateTime = Convert.ToDateTime("11:45 PM")
While (dtMod.TimeOfDay < target.TimeOfDay)
    dtMod = dtMod.AddMinutes(15)
    ddlFullTime.Items.Add(New ListItem(dtMod.ToShortTimeString, dtMod.ToShortTimeString))
    
End While

Why reinvent the wheel when you have guru_sami?

My brain is too slow and my loop sucked

Thanks for the code to sort of parse the date and time out.

I was almost there!
