Last time, we enumerated the contents of the Windows clipboard history from C++\/WinRT and C#<\/a>. Today we’ll do it from PowerShell.<\/p>\n

Because, hey, why not.<\/p>\n

$null = [Windows.ApplicationModel.DataTransfer.Clipboard, Windows.ApplicationModel.DataTransfer, ContentType=WindowsRuntime]\r\n$op = [Windows.ApplicationModel.DataTransfer.Clipboard]::GetHistoryItemsAsync()\r\n\r\n$result = Await<\/a> ($op) `\r\n    ([Windows.ApplicationModel.DataTransfer.ClipboardHistoryItemsResult])\r\n\r\n$textops = $result.Items.Content.GetTextAsync()\r\nfor ($i = 0; $i -lt $textops.Count; $i++){ Await($textops[$i]) ([String]) }\r\n<\/pre>\n
It’s basically the same thing we’ve been doing, just written in PowerShell. Note that I’m not a PowerShell expert, so some of the things I’m doing may be suboptimal.<\/p>\n
First, we load the Clipboard class into memory, specifying that it is a Windows Runtime class.<\/p>\n
Next, we call Get\u00adHistory\u00adItems\u00adAsync<\/code> and Await<\/code> it to get the history items result.<\/p>\n
We take the Items<\/code> from the result, get their Content<\/code>, and ask each Content<\/code> for its text.<\/p>\n
The text query is another asynchronous operation, so we iterate through the operations and Await<\/code> each one, sending the results back into the pipeline.<\/p>\n
I didn’t add the code to check ahead of time whether the content contained text. I just let the exception flow out of the Get\u00adText\u00adAsync<\/code> call. Fixing this is left as an exercise.<\/p>\n","protected":false},"excerpt":{"rendered":"
