强烈求教，关于打开窗口的问题。

[rextan]

在一个windows应用程序里面，为什么我用函数打开的窗口都是在加载状态或者是停在那里不能操作，而用button事件打开的窗口就正常显示呢。
为这个问题我已经郁闷了好久了，请各位指点指点。

[boyxia]

Form2 InputForm =new Form2();
InputForm.ShowDialog();或InputForm.Show();

我不信打不开

[rextan]

private void button_refresh_Click(object sender, System.EventArgs e)
{
this.ledshow.Close();
ledshow = new LedShow();
ledshow.Show();
}
private void label_status_TextChanged(object sender, System.EventArgs e)
{
button_refresh.PerformClick();
}
上面的事件打开的窗口就很正常，但是用下面这个事件打开的窗口就不正常。

[ljwpal]

我也不信！！！
Form Form1 =new Form();
Form1 .ShowDialog() ;

[qifanghcy]

private void button_refresh_Click(object sender, System.EventArgs e)
{
//this.ledshow.Close();
LedShow ledshow = new LedShow();
ledshow.Show();
}
private void label_status_TextChanged(object sender, System.EventArgs e)
{
button_refresh.PerformClick();
}
这样改就不会了!

[xaodoudou]

把　PerformClick 改成　
button_refresh_Click(new object(),new System.EventArgs())

[BlueLevin]

Form1 InputForm =new Form1();
Form1.ShowDialog();打开模式窗口
或InputForm.Show();打开窗口
觉得不会有问题啊，窗口也是类。和其它类一样。先实例化再调用方法，Show()就是显示的方法。也许你其它地方有问题!看一下别的代码!或者贴下代码给大伙看看!

小弟初学写的恶心不要见怪。

[Knight94]

试试下面的：
private void label_status_TextChanged(object sender, System.EventArgs e)
{
if(this.label_status.Text=="刷新")
{
------------------首先，确认是否执行到这里------------------
button_refresh_Click(new object(),new System.EventArgs());
------------------把上面改成“button_refresh.PerformClick();”----------
}
this.label_status.Text= "正在监听";
}

[rextan]

其实问题能不能打开窗口，只是private void label_status_TextChanged(object sender, System.EventArgs e)
{
if(this.label_status.Text=="刷新")
{
------------------首先，确认是否执行到这里------------------
button_refresh_Click(new object(),new System.EventArgs());
------------------把上面改成“button_refresh.PerformClick();”----------
}
this.label_status.Text= "正在监听";
}
这个方法打开的窗口不正常，处于加载状态的样子。

this.ledshow.Close();
改为
this.ledshow.Dispose();
