Windows注册表问题

Question

我正在尝试使用D语言修改注册表中的一些值，但是它一直给我以下错误提示：

无法设置值

然而，如果我在C#中写入完全相同的代码，则可以正常工作。这是D语言中注册表模块的问题还是我的使用方式存在问题？

module main;

import std.windows.registry;
import std.stdio;

import core.thread;

void main() {
    string languageName = "English";
    string languageCode = "en_uk";
    const uint languageValue = 0x00000001;
    writefln("Name '%s' Code '%s' Value '%s'", languageName, languageCode, languageValue);
    writeln("Press ENTER to change language.");
    readln();
    writefln("Changing language of Sims 2 to '%s' ...", languageName);
    Thread.sleep(dur!("msecs")(2000));
    string keyName;
    try {
        enum versions = [
            "",

你的 D 代码是否编译成了 64 位？ - Ben Voigt

另外，您是否以管理员身份运行该程序？ - Adam D. Ruppe

我正在使用32位编译，并以管理员身份运行。 - Bauss

你得到了什么确切的错误？是在你尝试的第一个子键上吗？它应该包含一个错误代码，我们可以查找。 - Adam D. Ruppe

是的，这是第一个问题，这是确切的错误 http://prntscr.com/764htu - Bauss

虽然我对 D 运行时一无所知，但错误代码 (5) 听起来像是 ERROR_ACCESS_DENIED。此外，如果你在 64 位系统上使用 32 位进程的 Reg* API，你不需要使用 Wow6432Node 路径，重定向会自动发生。 - bunglehead

Answer 1

由于您的系统有SOFTWARE\WOW6432Node注册表项，因此它是64位的。默认情况下，C#编译器（请参见/platform:anycpu，它也是VS中默认使用的）生成一个汇编程序，在64位系统上作为64位进程运行，在32位系统上作为32位进程运行。

另外，默认情况下，64位系统上32位进程的注册表查询会被重定向到特殊的WOW6432Node子项（例如，请求打开HKLM\Software实际上会打开HKLM\Software\WOW6432Node，请参见MSND文章"32-bit and 64-bit Application Data in the Registry"）。因此，您的32位D应用程序（就像您的C#应用程序如果以32位进程运行时所做的那样）实际上尝试打开不存在的SOFTWARE\Wow6432Node\Wow6432Node\EA GAMES\The Sims 2键。

要解决此问题，请使用64位模式编译D应用程序（-m64开关），或使用REGSAM.KEY_WOW64_64KEY禁用默认重定向：

Registry.localMachine.getKey(keyName, REGSAM.KEY_READ | REGSAM.KEY_WOW64_64KEY);

注意：如果C#作为32位进程在64位系统上运行，则可以使用RegistryView.Registry64来禁用默认重定向。
