Question

我正在尝试通过PowerShell使用Com插件打开Excel并继续获取＃34;呼叫被被叫方拒绝＆＃34;错误，请参阅下面的代码。有什么想法吗？

arr = [{label: "first", data: [1, 2]}, {label: "second", data: [3, 4, 5]}, {label: "third", data: []}, {label: "fourth", data: [6]}]

loop do
  arr.each do |hash|                               # go through each hash
    num = hash[:data].delete_at(0)                 # remove first element in data array
    puts "#{hash[:label]}: #{num}" unless num.nil? # output it if it's not nil(means array was empty)
  end
  break if arr.map { |i| i[:data] }.flatten == []  # stop if all arrays are empty
end

Call was rejected by callee. (Exception from HRESULT: 0x80010001
(RPC_E_CALL_REJECTED))

+ $a.Visible = $True

Answer 1

This reference更适合PowerShell用户。代码将消息过滤器附加到当前线程，顺便说一下，powershell必须在STA mode中运行（powershell 3.0 +的默认值）。

对于某些消息传递和重新调用excel之间的小暂停，我将此行添加到using声明列表中：

using System; 
using System.Runtime.InteropServices; 
using System.Threading;              // <- added this line

我将这些行添加到重试处理程序中：

if (dwRejectType == 2) 
// flag = SERVERCALL_RETRYLATER. 
{
    // Retry the thread call immediately if return >=0 &  
    // <100. 
    string wait_message = "Wait for Excel RPC channel";   // <- added this line
    Console.WriteLine(wait_message);                      // <- added this line
    Thread.Sleep(100);                                    // <- added this line
    return 99;
}

此外，如果用户碰巧碰到键盘或点击了一个可见的应用程序，Excel会连续抛出RPC_E_CALL_REJECTED，除非您在将应用程序实例设置为可见之前调用它。

$Application.Interactive = $false

在获取引用的脚本后，您的代码变为：

$a = New-Object -ComObject Excel.Application
AddMessageFilterClass 
$Application.Interactive = $false
$a.Visible = $True

Answer 2

仅供参考，例如，Visible为$false时也会发生这种情况：

New-Object -ComObject Excel.Application -Property @{Visible = $false}

另外，就我而言，它仅在通过WinRM启动时抛出错误；如果我在主机上执行了脚本，它就可以正常工作。
