VB.NET是如何关闭窗体

VB.NET关闭当前窗体me.close()

其它窗体用:窗体名.close(),例如:form2.close()

VB.Net 新手问题:如何关闭登录界面并跳到另一个界面

me.dispose()

楼主针对这个问题我也纠结过很久不过就在刚刚我找到了问题所在:

还是用me.close()

打开

项目

最下面一行有一个属性》

应用程序》下面

有一个关机模式

改为:当最后一个窗体关闭时。。。注意

me.close要写在窗体show()后面

例如

写成

f2.show()

me.close()

不要写成

me.close()

f2.show()

ASP.NET怎样用VB.NET代码实现关闭当前页面?

兼容ie和firefox js关闭代码

script language="javascript" type="text/javascript"

function closeWindow() {

window.open('','_parent','');

window.close();

}

/script

a href="javascript:closeWindow();"Close Window/a

好多朋友用到是自动关闭页面代码

script language="javascript"

function closeWindow(){

window.open('','_parent','');

window.close();

}

setTimeout("closeWindow()",3000);

/script
