vb.net编写卸载程序,vb怎么彻底卸载

如何用VB编写卸载程序

在所有kill执行完毕以后输出一个批处理文件，用途是删除卸载程序，在退出时调用它。

Private Sub Command1_Click()

Open App.Path + "\1.bat" For Binary As #1

Put #1, , "del " + App.EXEName + ".exe" vbCrLf

Put #1, , "del 1.bat"

Close #1

End Sub

Private Sub Form_Unload(Cancel As Integer)

Shell App.Path + "\1.bat"

End Sub

vb.net编程，如何使用 appdomain 实现某进程DLL动态加载和卸载?

由于你要求的是能够动态的加载与卸载,所以这里选用了appdomain的load方法来加载一个程序集(同样的,卸载的时候调用appdomain的静态方法Unload即可).

另外由于,在appdomain.load的时候remoting会试图将程序集序列化到defaultdomain中去,这会产生问题,通常以一个"FileNotFoundException"结束,因此采用了一种折中的办法.

思路如下:

1.建立一个新的程序集,里面包含一个轻量的类型,这个类型只包含一个用来加载程序集的公共方法;

2.在你的主程序里面,用appdomain.load来加载上一步的程序集,接着实例化上一步的轻量的类型;

3.而后就可以像操作通常的对象一样,调用它上面的方法来加载你想要的程序集了;

源代码已经打包发给你了,

用 VB.NET 语言编写GridView的删除,编辑

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

binddata()

End If

End Sub

Public Sub binddata()

'

End Sub

'编辑中

Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing

GridView1.EditIndex = e.NewEditIndex

'当前编辑行背景色高亮

GridView1.EditRowStyle.BackColor = Color.FromName("#F7CE90")

binddata()

End Sub

'分页

Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridView1.PageIndexChanging

GridView1.PageIndex = e.NewPageIndex

binddata() '重新绑定GridView数据的函数

End Sub

'更新

Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView1.RowUpdating

Dim clsB As New sqlDLTP.business

Dim sqlstr As String

Dim ds As New DataSet

sqlstr = "select hbdwno from etsshbd where hbdcnm='" CType(GridView1.Rows(e.RowIndex).FindControl("TextBox1"), TextBox).Text.ToString().Trim() "'"

ds = clsB.queryitems(sqlstr)

Dim wno As String = ds.Tables(0).Rows(0)(0).ToString().Trim()

sqlstr = "update etsdl set okscore1='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox6"), TextBox).Text.ToString().Trim() "',okscore2='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox7"), TextBox).Text.ToString().Trim() "',okscore='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox8"), TextBox).Text.ToString().Trim() "',okreport='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox9"), TextBox).Text.ToString().Trim() "',okgrad='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox10"), TextBox).Text.ToString().Trim() "',memo='" _

CType(GridView1.Rows(e.RowIndex).FindControl("TextBox12"), TextBox).Text.ToString().Trim() "' where trano='" _

GridView1.DataKeys(e.RowIndex).Value.ToString() "' and wno='" wno "'"

clsB.ExeSqlCmd(sqlstr)

GridView1.EditIndex = -1

binddata()

End Sub

'取消

Protected Sub GridView1_RowCancelingEdit(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCancelEditEventArgs) Handles GridView1.RowCancelingEdit

GridView1.EditIndex = -1

binddata()

End Sub

'删除

Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting

Dim clsB As New sqlDLTP.business

Dim sqlstr As String

Dim ds As New DataSet

sqlstr = "select hbdwno from etsshbd where hbdcnm='" CType(GridView1.Rows(e.RowIndex).FindControl("Label1"), Label).Text.ToString().Trim() "'"

ds = clsB.queryitems(sqlstr)

Dim wno As String = ds.Tables(0).Rows(0)(0).ToString().Trim()

sqlstr = "delete etsdl where trano=" GridView1.DataKeys(e.RowIndex).Value.ToString().Trim() "and wno='" wno "'"

clsB.ExeSqlCmd(sqlstr)

binddata()

End Sub

'绑定行，特效及链接列属性分配等

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

If e.Row.RowType = DataControlRowType.DataRow Then

'鼠标经过时，行背景色变

e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'")

'鼠标移出时，行背景色变

e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'")

' HyperLink列给链接值

CType(e.Row.Cells(1).FindControl("HyperLink1"), HyperLink).NavigateUrl = "javascript:void window.open('trashow.aspx?tno=" + CType(e.Row.Cells(1).FindControl("HyperLink1"), HyperLink).Text + "','', 'left='+(window.top.screen.width-454)/2+',top='+(window.top.screen.height-454)/2+',width=625,height=500,scrollbars=yes,resizeable=yes');"

'当有编辑列时，避免出错，要加的RowState判断

If e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate Then

If CType(e.Row.Cells(12).FindControl("Label11"), Label).Text = "1" Then

CType(e.Row.Cells(12).FindControl("Label11"), Label).Text = "在职"

End If

End If

End If

End Sub

前台：

asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width=100% BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" GridLines="None" AllowPaging="True" AllowSorting="True"

vb.net怎么加载和卸载窗体

VB.net 加载窗体 form2.show() 卸载窗体 me.close()加载窗体和VB没啥区别，而卸载就截然不同了。附：VB 加载窗体 form2.show 卸载窗体 unload me

卸载vb.net

vb.net会在系统里.net，要想手工删除几乎是不可能的，建议你还是原有的反安装程序来卸载。
