How can I have my WinForm return something to the caller so it knows which
button is clicked? The following is calling a system message box, just want
to do the samething with my own winform. Thanks.
If MsgBox("Data added.", MsgBoxStyle.OKCancel, "Message") = MsgBoxResult.OK
Then
' do something
End If
Simple example...
Create a solution with two forms, form1 and form2 copy in the following
code:
' Form1 Code
Imports System.Windows.Forms
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As
Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form
Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
