修复�q�程桌面�|�关

�H�然有一天，在iis服务器上上了一个新站点后，�q�程桌面�|�关�q�不上了。找不到原因�Q�于是我把rpc和rpcwithcert两个虚拟目录�l�删了。然后手动配�|?/p>

C:\Windows\System32\inetsrv\config\applicationHost.config文�g�Q�配了多�ơ仍然不行。于是把rpc onver htpp proxy反复安装�Q�rpc和rpccert虚拟目录完全没�Q何变化，无论我是否徏立还是删除�?br />

数日后我灵光一闪，会不会配�|�在注册表里�Q�在�|�上搜到到rpcproxy所在的注册表目录，hklm\software\microsoft\rpc\rpcprox�Q�把此目录删除，再把iis中的虚拟目录删除。然后重装rpc over http proxy�Q�这货终于给我自动徏产了rpc虚拟目录。然后再装远�E�桌面网养I��q�是不行。浏览iis的rpc里的文�g�Q�报500.19错误。上�|�查了下�Q�有��是因为在64位系�l�里启用�?2位的讄��引�v的。于是我才恍然大悟，我上站点那天�Q�新�E�序的功能只能在32位下跑，我把�E�序池改�?2位的了。于是我把程序池�Ҏ��64位的�Q�再用远�E�桌面终端去�q�，�l�于见到久违的登录界面，大功告成�?/p>

全局变量之苦

muroachanf — Wed, 13 Jun 2012 15:11:00 GMT

最�q�弄个项目，�H�然有点偏爱全局变量了，于是乎罔��教�U�书的教�Ԍ��大用特用�Q�一下就遇到了两个问题，兹记于此�Q�以作教训�?br />1、由于搞某种讑֤�的读写，针对每种讑֤�写一个工厂类�Q�然后声明一个设备管理类的全局变量�Q�在构造函数里把工厂类全注册到讑֤��理�c�M��。后来觉得这样不好，每加一�U�设备都要改构造函数的代码�Q�于是我��写了一个注册类�Q�在构造函数里�q�行注册�Q�然后在每个讑֤��cȝ��cpp里声明注册类的全局变量�?br />看�v来很完美�Q�于是我打了个lib�Q�弄到另一个dll工程里编译，�l�果��悲剧了�Q�注册类的构造函数死�z�M��q�行。最后发玎ͼ��~�译器认��个cpp的�Q何symbol都没被引用，�Ҏ��׃��~�译�q�来�Q�最后只好改回去�?br />
2、而后我又在dll工程里声明了一个全局变量�Q�然后在全局变量的构造函数里�Q�调用设备类的全局变量的成员获取设备列表，�l�果发现取出来是�I�的。最后发玎ͼ�讑֤��cȝ��构造函数在取设备列表时�q�没有被调用�Q�把初始化的代码�U�d��MFC的app.InitInstance里调用解决问题�?br />
�ȝ��下：1、在c#、delphi里用得很��的工厂注册�c�，在c++里是会被优化掉的�Q�千万用不得 2、�Q何情况下�Q�不应在全局变量的构造函数里引用其他全局变量�Q�这条应该不限于c++�?img src ="http://m.shnenglu.com/muroachanf/aggbug/178705.html" width = "1" height = "1" />
