IE8下debug模式的两个小问题

摘自互联网 留作备份

使用Visual Studio 2003/2005调试ASP.NET程序时出现如下错误，从而无法调试：
程序“[1912] w3wp.exe: DefaultDomain”已退出，返回值为 0 (0×0)。
对应的英文信息为：
The program ‘[5772] w3wp.exe: demo’ has exited with code 0 (0×0).
这个问题是IE8的 Loosely-Coupled Internet Explorer (LCIE) 引起的，解决方法如下：

对于Windows 2003/Windows XP 操作系统：
1) Open RegEdit //打开注册表编辑器
2) Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main //定位到【HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Internet Explorer/Main】
3) Add a dword under this key called TabProcGrowth //新建名称为 TabProcGrowth 的Reg_DWORD（整数值）
4) Set TabProcGrowth to 0 //设置 TabProcGrowth 的值为 0
重新启动调试，就恢复正常

如果是Vista或者更新的Win7上则需要：turn off protected mode。

VS 2005 Debugger crashing with IE 8 Beta 2

IE 8 has a feature called Loosely-Coupled Internet Explorer (LCIE) which results in IE running across multiple processes. http://www.microsoft.com/windows/internet-explorer/beta/readiness/developers-existing.aspx#lcie
Older versions of the Visual Studio Debugger get confused by this and cannot figure out how to attach to the correct process. You can work around this by disabling the process growth feature of LCIE. Here’s how:

1) Open RegEdit
2) Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main
3) Add a dword under this key called TabProcGrowth
4) Set TabProcGrowth to 0

Since you are running on Windows Server 2003, this is all you should need to do. If you run into the same problem on Vista or newer, you will also need to turn off protected mode.
