VB.NET关闭当前窗体me.close()
其它窗体用:窗体名.close(),例如:form2.close()
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()
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
