RegLoadMUIString Vista P-Invoke [英] RegLoadMUIString Vista P-Invoke
问题描述
您好，
我正试图以显示友好的
格式从注册表中获取MUI字符串。从我读过的，字符串格式如下：
a ?? @ [path] \dllname，-strIDa ??是MUI字符串并通过RegLoadMUIString API调用接收特殊处理。
这就是我提出来的电话：
[DllImport（" advapi32.dll"）]
内部静态extern long RegLoadMUIString（IntPtr hKey，string pszValue，
StringBuilder pszOutBuf，int cbOutBuf，out int pcbData，uint标志，字符串
pszDirectory）;
我正在使用指向打开的注册表项的有效指针调用此函数，
传入适当的值键（pszValue），其中MUI格式为
字符串。当我检查输出缓冲区（pszOutBuf）时，它总是一个空的
字符串。
有没有人能够让这个电话工作？我在网上找不到任何例子
。
谢谢，

Hello,
I''m trying to get an MUI string out of the registry in display friendly
format. From what I''ve read, strings in the following format:
a??@[path]\dllname,-strIDa?? are MUI strings and receive special handling via
the RegLoadMUIString API call.
This is what I have come up with for the call:
[DllImport("advapi32.dll")]
internal static extern long RegLoadMUIString(IntPtr hKey, string pszValue,
StringBuilder pszOutBuf, int cbOutBuf, out int pcbData, uint Flags, string
pszDirectory);
I''m calling this function with a valid pointer to an open registry key,
passing in the appropriate value key (pszValue) which has the MUI formatted
string. When I check the output buffer (pszOutBuf) it''s always an empty
string.
Has anyone been able to get this call to work? I cannot find any examples
on the web.
thanks,

推荐答案
下面是完整的代码：
使用System;
使用System.Collections.Generic;
使用System.Text;
使用System.Runtime.InteropServices;
使用Microsoft.Win32;
namespace ConsoleApplication2
{
class program
{
[DllImport（" advapi32.dll"）]
public static extern long RegOpenKeyEx（IntPtr hKey，string
lpSubKey，int ulOptions，int samDesired，out IntPtr phkResult）;
[DllImport（" advapi32.dll"）]
内部静态extern long RegLoadMUIString（IntPtr hKey，string
pszValue，StringBuilder pszOutBuf，int cbOutBuf，out int pcbData，uint标志，
string pszDirectory）;
[DllImport（" advapi32.dll"）]
public static extern int RegCl oseKey（IntPtr hKey）;
static void Main（string [] args）
{
try
{
//注意：测试Vista MUI注册表字符串
//注意：指向HKEYLM的指针
IntPtr localMachine = new
IntPtr（（long）unchecked（（int）0x80000002））;
//注意：regKey将包含指向开放注册表的指针
key
IntPtr regKey;
int pcbData = 0;
//注意：打开一个具有KEY_READ访问权限的设备密钥。
RegOpenKeyEx（localMachine，
@" SYSTEM \ CurrentControlSet \Control\Class \ {36FC9 E60-C465-11CF- 8056-444553540000}"，0,0x20019，out regKey）;
//注意：构建输出缓冲区引用
StringBuilder lptStr = new StringBuilder（ 1024）;
//注意：ClassDesc包含MUI格式的字符串
RegLoadMUIString（regKey，" ClassDesc"，lptStr，1024，out
pcbData，0，nu ll）;
//注意：关闭钥匙
RegCloseKey（regKey）;
//注意：输出值到控制台
Console.WriteLine（" Reg key：" + regKey.ToString（））;
Console.WriteLine（" LPTSTR：" + lptStr.ToString（））;
Console.WriteLine（" PCBDATA： " + pcbData.ToString（））;
Console.ReadLine（）;
}
catch（exception ex）
{
Console.WriteLine（" Exception：" + ex.Message）;
Console.ReadLine（）;
}
}
}

两个函数的返回类型应该是int，而不是long。

请回复到新闻组。
The return type for both functions should be int, not long.

将返回类型更改为int对调用结果没有影响。

Changing the return types to int had no affect on the outcome of the call.

两个函数的返回类型应为int，不长。
