如果不想关闭窗体，则使用e.Cancel = True
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
SaveSetting("appname", "Startup", "text1", TextBox1.Text)
SaveSetting("appname", "Startup", "text2", TextBox2.Text)
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim text1 As Double
Dim text2 As Double
text1 = GetSetting("appname", "startup", "text1", 8)
text2 = GetSetting("appname", "Startup", "text2", 6)
TextBox1.Text = text1
TextBox2.Text = text2
End Sub
只需要用变量存储 Image 对象，然后不需要的时候释放掉就行了。
Dim img1 As Image
img1 = Image.FromFile(pic)
PictureBox1.Image = img1
'窗口关闭时
img1 = Nothing
