问题描述

亲爱的所有

PLs帮助我希望我的所有表格中的更换者属性来自  sub / function

PLs Help MeI want changer property all my form from  sub/function

示例

我的程序

模块TestForm

  ;   Public Sub gsubSetRezise（ByRef vForm As System.Windows.Forms.Form）

        vForm.Left = 0

        vForm.Top = 0

        vForm.Width = 500

        vForm.Height = 400

Module TestForm
    Public Sub gsubSetRezise(ByRef vForm As System.Windows.Forms.Form)
        vForm.Left = 0
        vForm.Top = 0
        vForm.Width = 500
        vForm.Height = 400

         MsgBox（"gsubSetRezise上的宽度"&  vForm.name&""& vForm.Width） 

         MsgBox("width on gsubSetRezise " & vForm.name &" is " & vForm.Width) 

       退出Sub¥


   结束分组

结束模块

        Exit Sub

    End Sub
End Module

我的表格名称是test001

ON my form name is test001

公共类test01



    Private Sub test01_Lo​​ad（sender As Object，e As EventArgs）Handles MyBase.Load

        Dim cFrom As System.Windows.Forms.Form

        cForm =新test01

Public Class test01

    Private Sub test01_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim cFrom As System.Windows.Forms.Form
        cForm = New test01

       MsgBox（" width Before"& Me.Width）      

       MsgBox("width Before " & Me.Width)      

       致电gsubSetRezise（cForm）

        Call gsubSetRezise(cForm)

        MsgBox（" wdith After& Me.Width） 

        MsgBox("wdith After " & Me.Width) 

   结束分

$
 结束等级

    End Sub

 End Class

结果 我的程序

Result  my program

宽度40之前

width Before 40

gsubSetRezise test001的宽度为500 

width on gsubSetRezise test001 is 500 

宽度40后

width After 40

为什么不改变形成test01

Why form test01 with not change

推荐答案

而不是创建新表单（new test01）使用当前实例

instead of creating a new form (new test01) use the current instance

  Private Sub test01_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim cFrom As System.Windows.Forms.Form
        cForm = Me 'Me is a keyword, a reference to the current instance of the current class

       MsgBox("width Before " & Me.Width)      

        Call gsubSetRezise(cForm)

        MsgBox("wdith After " & Me.Width) 

    End Sub

或者只用"Me"来调用sub。作为参数：

or just call the sub with "Me" as parameter:

   Private Sub test01_Load(sender As Object, e As EventArgs) Handles MyBase.Load
       MsgBox("width Before " & Me.Width)      

        Call gsubSetRezise(Me)

        MsgBox("wdith After " & Me.Width) 

    End Sub
