通过PowerShell加载类型库并编写Windows Live Writer脚本 [英] Loading a Type Library via PowerShell and scripting Windows Live Writer

问题描述

总体来说，我对COM和Windows编程/脚本非常陌生。我试图做的是编写Windows Live Writer脚本。根据文档，然后我才能调用

I'm very new to COM and Windows programming/scripting in general. What I was trying to do is scripting Windows Live Writer; according to the documentation before I can call

  $o = New-Object -c WindowsLiveWriter.Application

我需要先加载TLB，所以我应该调用 add-type 命令，不幸的是它失败了：

I need to load the TLB first, so I should call the add-type command, unfortunately it fails:

PS C:\Users\NoWhereMan> add-type windowslivewriter.application
Add-Type : c:\Users\NoWhereMan\AppData\Local\Temp\a7ifbimo.0.cs(1) : A namespace does not directly contain members such
 as fields or methods
c:\Users\NoWhereMan\AppData\Local\Temp\a7ifbimo.0.cs(1) : >>> windowslivewriter.application
At line:1 char:9
+ add-type <<<<  windowslivewriter.application
    + CategoryInfo          : InvalidData: (c:\Users\NoWher...elds or methods:CompilerError) [Add-Type], Exception
    + FullyQualifiedErrorId : SOURCE_CODE_ERROR,Microsoft.PowerShell.Commands.AddTypeCommand

Add-Type : Cannot add type. There were compilation errors.
At line:1 char:9
+ add-type <<<<  windowslivewriter.application
    + CategoryInfo          : InvalidData: (:) [Add-Type], InvalidOperationException
    + FullyQualifiedErrorId : COMPILER_ERRORS,Microsoft.PowerShell.Commands.AddTypeCommand

，我正在运行Windows7 x64

编辑：x64是关键问题，我需要将PSH作为x86进程运行

EDIT: x64 was the key issue, I needed to run PSH as a x86 process

谢谢

推荐答案

从帮助添加类型：

将Microsoft .NET Framework类型（一个类）添加到Windows PowerShell会话中。

Adds a Microsoft .NET Framework type (a class) to a Windows PowerShell session.

但 windowslivewriter.application 不是.NET类型。

PowerShell（PSH）直接支持COM对象，不需要带加载类型库（TLB） ¹ 的任何特殊步骤，只需按照文档。例如：

PowerShell (PSH) directly supports COM objects, you do not need to take any special steps to load the Type Library (TLB)¹, just call the methods diretcly as given in the documentation for the component. E.g.:

$lw = New-Object -com WindowsLiveWriter.Application   
$lw.NetPost()

启动新的帖子编辑器。

摘要：您不需要不需要首先加载TLB。

Summary: you do not need to load the TLB first.

在64位Windows下，您可能需要确保正在运行32位实例（ x86 ），以执行此操作（取决于Live Writer组件是在进程中运行还是在进程外运行）。

Under 64bit Windows, you might need to ensure you are running a 32bit instance ("x86") of PSH to do this (depending if the Live Writer component runs in or out of process).

¹ 严格来说，这仅适用于支持使用IDispatch编写脚本的COM类型，但实际上很少有不支持的类型。

¹ Strictly speaking, this only applies to COM types that support scripting with IDispatch, but in practice there are few that don't.
