如何检测在sperate表单上按下按钮的时间 [英] How do I detect when a button is pressed on a sperate form

问题描述

在我的第一个表格中，我有四个按钮。程序启动时，其中2个被禁用。在form2中，当我按下Form2中的按钮时，我希望启用2个禁用按钮。



我尝试过：



我尝试过使用

如果Form2.FinishButton_Click = True那么

PrintButton.Enabled = True

SendButton.Enabled = True

结束如果

In my first form, I have four buttons. 2 of them are disabled when the program starts. In form2 I want the 2 disabled buttons to be enabled when I press a button in Form2.

What I have tried:

I have tried using
If Form2.FinishButton_Click = True Then
PrintButton.Enabled = True
SendButton.Enabled = True
End If

推荐答案

在带有FinishButton的表单上：

On the form with FinishButton:

Private Sub FinishButton_Click(sender As Object, e As EventArgs) Handles FinishButton.Click

Form1.PrintButton.Enabled = True
Form1.SendButton.Enabled = True
End Sub

将Form1替换为PrintButton&的形式名称。 SendButton

Replace "Form1" with the name of the form of PrintButton & SendButton

'在第一种形式中，您必须在Form2.tag属性中发送form1，如下所示

'In first form you have to send the form1 in Form2.tag property like below

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
              Dim frm2 As New Form2
              frm2.Tag = Me
              frm2.Show()
  End Sub

'以下代码在Form2中

'Below codes are in Form2

Private frmlog As Form

   Private Sub Form2_Load(sender As Object, e As EventArgs) Handles Me.Load
       If Not IsNothing(Me.Tag) Then
           Frm1 = DirectCast(Me.Tag, Form)
           Frm1.Hide()

       End If
   End Sub

'以下代码在Form2中

'Below codes are in Form2

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
         Form1.button1.Enabled = True
         Form1.button2.Enabled = True
  End Sub

你的代码是无意义的，因为它显示...



你需要做的是：

在Form2上捕获FinishButton.Click-Event（使用方法）。

在这个方法中你可以设置'Form1 .PrintButton.Enabled = True'以及'Form1.SendButton.Enabled = True'

Your Code is nonsense as it's shown ...

What you have to do is :
Catch the FinishButton.Click-Event on Form2 (with a method).
Inside this method you can set the 'Form1.PrintButton.Enabled = True' and also the 'Form1.SendButton.Enabled = True'
