解决方案

看看这个： Form.ShowDialog [ ^ ]。阅读完毕后，您应该能够完成此任务。

要在主应用程序中显示子表单，您必须先在应用程序中定义子表单，然后根据您的方法调用以下方法需要。

例如：此示例将您的子表单显示为模型对话框，阻止用户访问主表单，除非他/她关闭子表单。

  private   void  child1Button_Click（ object  sender，EventArgs e）
 {
 Form2 testDialog =  new  Form2（）; 
 
  //  将testDialog显示为模态对话框并确定DialogResult = OK。 
  if （testDialog.ShowDialog（ this ）== DialogResult.OK）
 {
  //  执行成功操作 
} 
  else  
 {
  //  子表单取消 
} 
 testDialog.Dispose（）; 
 
} 
 

将您的孩子显示为无模式对话框。

  private   void  child1Button_Click（ object  sender，EventArgs e）
 {
 Form2 testDialog =  new  Form2（）; 
 testDialog.Show（）; 
}

hi bikramjeet，

我遇到了你的问题。我在创建许可应用程序时也遇到了同样的问题。幸运的是我看到了你的问题。



我认为以下代码（vb.net）将解决你的问题

 Dim frm As new frmLicense 
 Private Sub MainForm_Activated（ByVal sender As Object，ByVal e As System.EventArgs）Handles Me.Activated 
如果不是frm.IsDisposed那么
 frm.Focus（）
结束如果
结束Sub 
 
 Private Sub MainForm_Load（ByVal sender As Object，ByVal e As System.EventArgs ）Handles Me.Load 
 frm.TopMost = True 
 frm.Show（）
 End Sub 

我写了简单的代码。 frmlicense是您的许可证激活弹出窗体。如果你愿意，我建议让它成为单身人士。你可以使用任何转换器来获取c＃代码。不要以为它需要。



这肯定会解决你的问题。如果你觉得这个合适，那就接受为解决方案。所以对其他人也有帮助。

解决方案

Have a look at this: Form.ShowDialog[^]. You should be able to accomplish this after reading that.

To display a child forms from your main application you have to first define your child forms in your application and call the following methods based on your need.
eg: This examples displays your child form as Model dialog which blocks the user to access the main form unless he/she close the child form.

private void child1Button_Click(object sender, EventArgs e)
{
  Form2 testDialog = new Form2();

  // Show testDialog as a modal dialog and determine if DialogResult = OK.
  if (testDialog.ShowDialog(this) == DialogResult.OK)
  {
     //do success operation
  }
  else
  {
     // Child form is cancelled
  }
  testDialog.Dispose();

}

To display your child as Modeless dialog.

private void child1Button_Click(object sender, EventArgs e)
 {
   Form2 testDialog = new Form2();
   testDialog.Show();
 }

hi bikramjeet,
I got your problem. I also faced same problem while creating licensed application.Luckily i saw your problem.

I think following code (vb.net) will solve your problem

Dim frm As New frmLicense
    Private Sub MainForm_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
        If Not frm.IsDisposed Then
            frm.Focus()
        End If
    End Sub

    Private Sub MainForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        frm.TopMost = True
        frm.Show()
    End Sub

I have written simple code. frmlicense is your license activation popup form. I suggest make it singleton if u want. U can use any converter to get c# code. don''t think its needed.

This will definitely solve your problem. If u find this suitable,accept as solution.So it will be helpful to other also.
