Question

Hallo
I design project in which is main window with mdi container and mdi child windows. My problem is that so i want to save value from TextBox1 from child form using main menu which is in main window. I don't know how to call content of TextBox1. Here is part
of code about saving file.
Private Sub MenuItem5_Click(sender As Object, e As EventArgs) Handles MenuItem5.Click
If Me.ActiveMdiChild IsNot Nothing Then
SaveFileDialog1.FileName() = "Nowa metryka"
SaveFileDialog1.Filter() = "Metryka zaworu bezpieczenstwa (*.mzb) | *.mzb"
If SaveFileDialog1.ShowDialog() = DialogResult.OK Then
Dim ZapisywanieTekstu As New IO.StreamWriter(SaveFileDialog1.FileName)
Dim varZapisywanyTekst As String = ZapisywanieTekstu.AutoFlush
ZapisywanieTekstu.WriteLine("HERE SHOUL BE A CALL TO TextBox1 VALUE")
ZapisywanieTekstu.Close()
End If
End If
End Sub
