I found a lot of nice icons from Microsoft Office 2007. Do you any idea for extract & save all icons as PNG files by using VBA?

Partial ImageMSO http://rabu4g.bay.livefilestore.com/y1p2SF1q63YjDjPNmK4nYMW2644r9AO2aAsE__vBYznTeXD0b4SJUU0O07fxPD0r7aO_83gCJ-8OfcOQsFKG0fQMRnTEneBU1TI/Capture.PNG

The following code is code which is used to get image from ImageMSO. 

Application.CommandBars.GetImageMso([name], [width], [height])

I can display all as PictureBox control and save excel file as web page. However, every icons is very low quality.

Moreover, I try to create C# Excel Add-in project for exporting as Bitmap object by using the following code. But I found that it can't export as semi-transparent PNG.

stdole.IPictureDisp p = Application.CommandBars.GetImageMso(fileName, size, size);
Bitmap b = Bitmap.FromHbitmap((IntPtr)p.Handle, (IntPtr)p.hPal);

PS. I want to save all icons as PNG format because I need to use semi-transparent feature of it. It allow me to use all icons on most background color more than white background.

我在 Excel 开发中经常使用 ImageMso。偶然发现这篇文章后，我更进一步，将一个包放在一起，以直观地搜索、提取和保存 Microsoft Excel 中的图标作为文件或复制并粘贴（具有 alpha 通道透明度）到另一个应用程序。我还从各种来源编制了一份包含 8,899 个不同 ImageMso 名称的列表。我希望其他人可以发现这很有用。

我已经完成了一个 C# Utility 类，用于将 Office2007 画廊图标提取到 .png 文件，同时正确地保持它们的透明度。主要代码取自 Andrew Whitechapel 撰写的一篇精彩文章 ( http://blogs.msdn.com/b/andreww/archive/2007/10/10/preserving-the-alpha-channel-when-converting-images。 .aspx）。我已将其与 Office 2007 示例图标表集成，以防您要将所有这些图标提取到目标文件夹。

步骤是：

1) 在http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=11675下载 Office Gallery 电子表格

2) 使用 Office2007IconsGallery.xlsm 示例电子表格的位置以及您想要提取图标的目标文件夹调用 OfficeIcons.ExtractAllIcons()。

所有的 PNG 文件都可以在这里找到。这些都是 PNG 格式的。好编程！（这里也提供了一个不错的 ZIP 存档） ZIP 存档包含所有 17 个 Excel 图标。

当您使用 GetImageMso 方法时，您最终会得到对象的 IPicture 接口。IPicture 界面访问适合以原始格式保存到文件的图标 - .ICO、.WMF 或 .BMP 不支持 PNG 格式。以下链接解释了为什么这不能直接实现：

http://msdn.microsoft.com/en-us/library/aa434604.aspx（msoGetImageMso 方法 ） http://msdn.microsoft.com/en-us/library/ms680761%28VS.85%29.aspx（IPicture接口） http://msdn.microsoft.com/en-us/library/ms694504%28VS.85%29.aspx （另存为文件方法）

但是，使用更复杂的方法将产生您想要的结果：

我已经尝试过 Ismail 的回答，效果很好。然而，我花了一段时间才弄清楚如何让它工作。我可以分享一点知识：

该解决方案需要来自 codeplex: link的 ExcelDna 。

当我使用时，Net 4.0我没有.zip支持，所以我首先将.xslm文件解压缩到一个平面目录结构，然后我将代码更改为直接从文件中读取。然后在 Excel 中，我将 ExcelDna 扩展方法称为

=ExtractIcons("Office2207IconsGallery";"folder_where_to_store_icons")

实用程序类的 using 语句（对我而言）：

using System.Xml.Linq;

using System.IO;

using System.Drawing;

using System.Runtime.InteropServices;

using System.Drawing.Imaging;

using Application = Microsoft.Office.Interop.Excel.Application;

using ExcelDna.Integration;

using stdole;

希望这会有所帮助....谢谢伊斯梅尔！
