passing variables to other windows

When I double click on a name a pop up window appears with this person's data (method show()) how can I pass a variable to that new window from the window I double clicked on?

Thanks in advance.

like this?

VB Code:

Private Sub Label1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.DoubleClick
        Dim f As New Form5()
        f.Label1.Text = Me.Label1.Text
        f.Show()
    End Sub

Well almost, the thing is that the variable isn't to be shown it is just an internarl ID number to retriever information from a database. So i want to pass it to do, in the popping form, something like "select * from customers where idcustomers=variable".

Hey thanks.

this sample :bigyello:

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f As New Form5()
        f.generateId(Me.TextBox1.Text)
        f.Show()
    End Sub

in Form5:

VB Code:

Dim cn As New SqlConnection("user id=sa; password=password; initial catalog=northwind")
 
    Sub generateId(ByVal s As String)
        Dim cmdText As String = "select* from student where Idno = '" & s & "'"
        cn.Open()
        Dim cm As New SqlCommand(cmdText, cn)
        Dim dr As SqlDataReader = cm.ExecuteReader
        While dr.Read
            TextBox1.Text = dr.GetValue(1).ToString 'lastname
        End While
        dr.Close()
        cn.Close()
    End Sub
