如何從shell32.dll中獲取圖標？

Question

我想要樹圖標用於本地應用程序。有誰知道如何將圖像提取爲.icon文件？我喜歡16x16和32x32，或者我只是做一個屏幕截圖。

Answer 1

在Visual Studio中，選擇「文件打開...」，然後選擇「文件...」。然後選擇Shell32.dll。應打開文件夾樹，並在「圖標」文件夾中找到圖標。

要保存圖標，您可以右鍵單擊文件夾樹中的圖標並選擇「導出」。

Answer 2

另一種選擇是使用工具，如ResourceHacker。它處理方式不僅僅是圖標。乾杯!

Answer 3

Resources Extract是另一種從遞歸查找很多DLL中的圖標的工具，非常方便的IMO。

Answer 4

只需用IrfanView打開DLL並將結果保存爲.gif或.jpg。

我知道這個問題很舊，但它是第二次谷歌命中「提取圖標從DLL」，我想避免在我的工作站上安裝任何東西，我記得我使用IrfanView。

Answer 5

如果您在Linux上，可以使用gExtractWinIcons從Windows DLL中提取圖標。 它在Ubuntu和Debian中的gextractwinicons包中可用。

此博客文章有screenshot and brief explanation。

Answer 6

您可以下載免費軟件Resource Hacker，然後按照下面的說明：你想從發現圖標

1. 打開任何一個dll文件。
2. 瀏覽文件夾以查找特定圖標。
3. 從菜單欄中選擇'操作'，然後'保存'。
4. 爲.ico文件選擇目的地。

Answer 7

我需要從shell32.dll中提取圖標＃238，不想下載Visual Studio或Resourcehacker，所以我發現一對夫婦PowerShell腳本從的Technet（感謝約翰·建富和＃https://social.technet.microsoft.com/Forums/windowsserver/en-US/16444c7a-ad61-44a7-8c6f-b8d619381a27/using-icons-in-powershell-scripts?forum=winserverpowershell）做了類似的事情，並創建了一個新的腳本（以下）以滿足我的需求。

我輸入的參數爲（來源DLL的路徑，目標圖標文件名和DLL文件中的圖標索引）：

C：\ WINDOWS \ SYSTEM32 \ shell32.dll中

C：\ TEMP \ Restart.ico

我發現我需要的是通過試驗和錯誤通過臨時創建一個新的快捷方式＃238圖標指數（在桌面上單擊鼠標右鍵，選擇新建 - >快捷方式和鍵入calc並按Enter兩次）。然後右鍵單擊新的快捷方式並選擇屬性，然後在快捷方式選項卡中單擊「更改圖標」按鈕。粘貼到路徑C：\ Windows \ System32 \ shell32.dll中，然後單擊確定。找到你想使用的圖標並找出它的索引。注意：索引＃2在＃1之下，而不在右邊。圖標索引＃5在我的Windows 7 x64機器上位於第二列的頂部。

如果任何人有一個更好的方法，同樣的作品，但獲得更高質量的圖標，那麼我會很有興趣聽到它。謝謝，肖恩。

.SYNOPSIS 
    Exports an ico and bmp file from a given source to a given destination 
.Description 
    You need to set the Source and Destination locations. First version of a script, I found other examples but all I wanted to do as grab and ico file from an exe but found getting a bmp useful. Others might find useful 
    No error checking I'm afraid so make sure your source and destination locations exist! 
.EXAMPLE 
    .\Icon_Exporter.ps1

$icon.save($stream) 
$stream.close()

這是以上解決方案的更新版本。 我添加了一個被隱藏在鏈接中的缺少的程序集。 新手不會理解這一點。 這是示例將運行沒有修改。

.SYNOPSIS

.Description 
    You need to set the Source and Destination locations. First version of a script, I found other examples 
    but all I wanted to do as grab and ico file from an exe but found getting a bmp useful. Others might find useful 
.EXAMPLE 
    This will run but will nag you for input 
    .\Icon_Exporter.ps1 
.EXAMPLE 
    this will default to shell32.dll automatically for -SourceEXEFilePath 
    .\Icon_Exporter.ps1 -TargetIconFilePath 'C:\temp\Myicon.ico' -IconIndexNo 238 
.EXAMPLE 
    This will give you a green tree icon (press F5 for windows to refresh Windows explorer) 
    .\Icon_Exporter.ps1 -SourceEXEFilePath 'C:/Windows/system32/shell32.dll' -TargetIconFilePath 'C:\temp\Myicon.ico' -IconIndexNo 41

Answer 9

如果有人正在尋找一種簡單的方法，只要使用7zip的解壓shell32.dll中並查找文件夾的.src/ICON/
