Then first, you need a form for data collection. All data must be saved in your database so in the retrieval section, when lest say a company_ID or name is entered in a text box and the 'ENTER' key is pressed, all details(description) of the company saved in the database would be retrieved.
That's a start point. You must have a data source if you want to retrieve data.
Private Sub textBox1_KeyDown(sender As Object, e As KeyEventArgs)
If e.KeyCode = Keys.Enter Then
textBox2.Text = GetData(textBox1.Text.Trim())
Private Function GetData(str As String) As String
Dim strReturn As String = ""
Select Case str
strReturn = "My 1st company name"
strReturn = "My 2nd company name"
But this is an exmple code, I dont know where you will get the data, but this is one of choices to use (using switch statement).
