我有一个类需要知道当前有效的用户名.Environment.UserName或是WindowsIdentity.GetCurrent().Name为了那个.但是当启用模拟时,它们返回的LocalUser名称不是ImpersonatedUser名称.
如何获取当前模拟用户的姓名？
该应用程序是C#控制台应用程序,我知道模仿是有效的,因为我获得了特权ImpersonatedUser.当然,我可以使用模拟代码将模拟的用户名保存到某个全局变量,但这样做是错误的.
更新:
模拟代码:
if (LogonUser(userName, domain, password, LOGON32_LOGON_NEW_CREDENTIALS/*=9*/, LOGON32_PROVIDER_DEFAULT, ref token) != 0)
{
if (DuplicateToken(token, 2, ref tokenDuplicate) != 0)
{
WindowsIdentity tempWindowsIdentity = new WindowsIdentity(tokenDuplicate);
_impersonationContext = tempWindowsIdentity.Impersonate();
// WindowsIdentity.GetCurrent().Name equals "LocalUser"
// while userName equals "ImpersonatedUser"
...
我可以控制模拟代码,但我更愿意将其与解决方案的其他部分保持独立.
Hi all,
我正在调试一个设备驱动程序,我得到一个内核恐慌.检查回溯或错误日志后,似乎问题出在kmalloc上.我想也许我可以用其他分配函数改变kmalloc.他们有什么不同？
这是错误日志:

但我只是看不出这可能是个问题......
在阅读Git pre-commit hook:更改/添加文件后,出现以下问题:
鉴于我有一个包含分阶段和非分阶段更改的文件,如何在分段后显示文件内容的预览？
例:
echo "foo" >> file
git add file
echo "bar" >> file
通缉输出:
[previous contents of file]
foo
当我们使用模拟器并将文件存储在隔离存储中时.文件实际存储在计算机上的哪个位置？我的意思是路径.
我正在尝试使用http://crossgcc.rts-software.org/doku.php?id=i386linuxgccformac中的文件进行交叉编译
我在Intel Mac(10.6.6,x86_64)我编译:gmp,mpfr,mpc为交叉编译器为32bit(因为我在64位Mac上)但我得到了
ld: warning: option -s is obsolete and being ignored
ld: warning: ignoring file /gmp1/lib/libmpc.dylib, file was built for unsupported file format which is not the architecture being linked (i386)
ld: warning: ignoring file /gmp1/lib/libmpfr.dylib, file was built for unsupported file format which is not the architecture being linked (i386)
ld: warning: ignoring file /gmp1/lib/libgmp.dylib, file was built for unsupported file format which is not the architecture being linked (i386)
在编译GCC时:

简单的开始是将它们读取到TStringList,但是用于比较两个文本文件的代码要复杂得多,而且DUnitGui中的gui对此不够.
任何的想法？建议？
我正在尝试使用preg_match()使用PHP验证DD/MM/YYYY等日期.这是我的REGEX表达式的样子:
$pattern = "/^([123]0|[012][1-9]|31)/(0[1-9]|1[012])/(19[0-9]{2}|2[0-9]{3})$/";
但是使用正确的值,我得到这样的信息:
preg_match():未知的修饰符'('
完整代码:
$pattern = "/^([123]0|[012][1-9]|31)/(0[1-9]|1[012])/(19[0-9]{2}|2[0-9]{3})$/";
$date = "01/03/2011";
if(preg_match($pattern, $date)) return TRUE;
先感谢您
