vb.net 窗体设计常用技巧

这里打算收集vb.net 窗体设计的常用技巧，用的时候不至于每次都从头来过

1.子窗口（体）在父窗口（体）居中

Dim tempRect As New Rectangle(frmM.Left + (frmM.Width - Me.Width) / 2, frmM.Top + (frmM.Height - Me.Height) / 2, 866, 537)

DesktopBounds = tempRect

备注：frmM是父窗口，最后的866，537分别为子窗口的宽度和高度

2.按ESC键退出

    Private Sub form_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
        If e.KeyChar = Chr(27) Then
            Me.Close()
        End If
    End Sub

具体chr对应的数值，查标准ASCII表

3.tooltip用法
        ToolTip1.SetToolTip(控件名, "字符")

4.vb.net 随windows开机启动

        Dim StartupKey As Microsoft.Win32.RegistryKey

        StartupKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Run", True)
        If chkAutoStart.Checked Then
            StartupKey.SetValue("SiteM", Application.ExecutablePath & " -startup")
        Else
            StartupKey.DeleteValue("SiteM", False)
        End If
