参考

Dim sdt As Date = Date.Now
While Date.Now < sdt.AddSeconds(10)
    Application.DoEvents
End While

msgbox("10秒后执行")

老师，这个延迟执行没怎么用来，比如我在窗口的afterload事件，红色代码需要等到窗口打开后10s后才执行，应该怎么写？

Dim lvw As WinForm.ListView = e.Form.Controls("ListView1")
lvw.StopRedraw() \'停止绘制
lvw.Groups.Clear() \'清除原来的分组
lvw.Columns.Clear() \'清除原来的列
lvw.Rows.Clear() \'清除原来的行
lvw.Images.Clear() \'清除原来的图片
lvw.View = ViewMode.Details \'显示模式为详细信息
lvw.TitleSize = New Size(130,80) \'设置平铺区域大小
lvw.GridLines  = True \'显示网格线
Dim cls() As String = {"名称"} \'定义列名
Dim wds() As Integer = {100} \'定义列宽
For i As Integer = 0 To  cls.Length - 1  \'增加列
    Dim c As WinForm.ListViewColumn = lvw.Columns.Add()
    c.Name = cls(i) \'指定列名
    c.Text = cls(i) \'指定标题,这里标题和列名相同
    c.Width = wds(i) \'指定列宽
Next
For Each zh As String In DataTables("子系统导航").GetValues("分组","","序号") \'增加分组
    Dim grp As WinForm.ListViewGroup = lvw.Groups.Add()
    grp.Name = zh
    grp.Text = zh
Next
For Each dr As DataRow In DataTables("子系统导航").DataRows
    Dim Key As String = dr("图标")
    Dim r As  WinForm.ListViewRow =  lvw.Rows.Add() \'增加一行
    lvw.Images.AddImage(Key, Key, Key) \'添加代表这个名称的一对图标
    r.ImageKey = Key \'指定图标键值
    r.Group = dr("分组") \'指定所属分组
    r.Tag = dr
    For Each cl As String In cls \'逐列取值
        r(cl) = dr(cl)
    Next
Next
lvw.ResumeRedraw() \'恢复绘制
lvw.View = ViewMode.LargeIcon \'显示模式切换为大图标

\'延迟10s执行下列代码

If _Fuzeren = Nothing OrElse _Fuzerendianhua = Nothing OrElse _Dengjiren = Nothing OrElse _Dengjirendianhua = Nothing Then
    MessageBox.Show("第一次登录,请先完善项目基本信息!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
    Forms("项目信息").Open()
End If

任意地方加入，红色代码，写你需要执行的代码

Dim sdt As Date = Date.Now
While Date.Now < sdt.AddSeconds(10)
    Application.DoEvents
End While

msgbox("10秒后执行")

用异步函数处理
