如何在vb.net中关闭表单 [英] how to close a form in vb.net

问题描述

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If File.Exists("c:\hi.txt") Then
            Me.Hide()
            successform.Show()
        Else
            Me.Show()
        End If
    End Sub

当hi.txt文件退出successform.show()仅应可见，然后自我形式应关闭.但是即使hi.txt存在，我也得到两种形式.

when hi.txt file exits successform.show() only should visible then self form should close. but i am getting both form even though hi.txt exists

Umapathi K asked:

self表单应关闭

如果进程与程序无关，则无法执行此操作.
试试这个:

This could not be if done if processes are not interrelated to the program.
Try this:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If File.Exists("c:\hi.txt") Then
            Me.Hide()
            successform.Show()
        Else
            Me.Show()
            successform.Hide()'You missed this.
        End If
    End Sub

您错过了隐藏成功表单的功能.
