使用jscript检测exe的版本和公司名称 [英] Detecting the version and company name of an exe using jscript

问题描述

我知道如何使用jscript检索exe的版本，但我找不到任何方法来检索公司，内部名称或产品名称等其他信息。

I kwnow how to retrieve the version of an exe using jscript, but I can't find any way to retrieve other info like "Company", "Internal name" or "Product name".

function version_of( file_name ) 
{
   var fso = new ActiveXObject("Scripting.FileSystemObject");
   var f;
   try {
      f = fso.GetFile( file_name )
   } catch( e ) {
      throw new Error( e.number, "Error retrieving version of file ``" + file_name + "'': " + e.description );
   }
   var v = fso.GetFileVersion( f );
   if ( !v ) {
      throw new Error( 1, "File ``" + file_name + "'' has not got a version" );
   }
   return v;
}

WScript.Echo( version_of( "c:\\windows\\system32\\winver.exe" ) );

也许我会编写自己的COM对象来完成工作......

Maybe I will write my own COM object to do the job...

推荐答案

可以使用 GetDetailsOf 方法 文件夹 对象。该方法采用与扩展属性关联的从零开始的索引号，并将属性值作为字符串返回。通常， GetDetailsOf 可用于检索可在详细的Shell视图中显示的任何类型的信息（查看 - >选择详细信息）。请参阅检索扩展文件属性。

Extended file properties, such as company name or product name, can be obtained in scripts using the GetDetailsOf method of the Shell Folder object. The method takes a zero-based index number associated with the extended property and returns the property value as a string. In general, GetDetailsOf can be used to retrieve any type of information that can be displayed in the detailed Shell view (View -> Choose Details). See Retrieving Extended File Properties.

唯一的问题是不同的Windows版本提供不同的扩展文件属性集。例如，Windows XP有34个文件属性，Windows Vista— 266，Windows 7— 284.不仅属性索引可以不同，而且属性名称（Windows XP中的持续时间 = Windows Vista中的长度），这是非常令人困惑的。有关可用文件属性及其索引号的完整列表，请参阅此页面或使用类似这样的脚本：

The only problem is that different Windows versions offer different sets of extended file properties. For example, Windows XP has 34 file properties, Windows Vista — 266, Windows 7 — 284. Not only the property indexes can differ, but also the property names (Duration in Windows XP = Length in Windows Vista), which is quite confusing. For a full list of available file properties and their index numbers, see this page or use a script like this one:

var oShell = new ActiveXObject("Shell.Application");
var oFolder = oShell.Namespace("C:");

for (var i = 0; i < 300 /* some large number*/; i++)
  WScript.Echo(i + " " + oFolder.GetDetailsOf(null, i));

无论如何，这是在Windows Vista上执行任务的示例代码。我找不到内部名称属性（可能没有正确搜索），因此包含文件版本和产品版本：

Anyway, here's sample code to perform your task on Windows Vista. I couldn't find the Internal Name property (might not have searched properly) so included the File Version and Product Version instead:

var COMPANY_NAME    = 33;
var FILE_VERSION    = 145;
var PRODUCT_NAME    = 251;
var PRODUCT_VERSION = 252;

var oShell  = new ActiveXObject("Shell.Application");
var oFolder = oShell.Namespace("C:\\Windows");
var oFile   = oFolder.ParseName("notepad.exe");

WScript.Echo("Company name: " + oFolder.GetDetailsOf(oFile, COMPANY_NAME));
WScript.Echo("Product name: " + oFolder.GetDetailsOf(oFile, PRODUCT_NAME));
WScript.Echo("File version: " + oFolder.GetDetailsOf(oFile, FILE_VERSION));
WScript.Echo("Product version: " + oFolder.GetDetailsOf(oFile, PRODUCT_VERSION));

请注意，您可以使用 GetDetailsOf（null，property_index）获取特定于语言环境的属性名称（这在非英语Windows版本上非常有用）：

Note that you can use GetDetailsOf(null, property_index) to get locale-specific property names (this can be useful on non-English Windows versions):

WScript.Echo(oFolder.GetDetailsOf(null, COMPANY_NAME) + ": " + oFolder.GetDetailsOf(oFile, COMPANY_NAME));
