Hi,

是否可以使用ThumbnailCacheId检索指定jpeg的缩略图?

Is there a way to use a ThumbnailCacheId to retrieve a thumbnail for a specified jpeg?

我正在使用Windows Search SQL检索一组jpeg图像的图像信息，并且我需要一种快速的方法来为每个图像检索相应的缩略图.我找到了一个名为ThumbnailCacheId的WS列，该列返回一个唯一的数字，我假设该数字可用于从Thumbs.db中检索缩略图.

I’m using Windows Search SQL to retrieve picture information for a set of jpeg images, and I need a fast way to retrieve the corresponding thumbnails for each image. I have found a WS column called ThumbnailCacheId which returns a unique number and I’m assuming the number can be used to retrieve the thumbnail from Thumbs.db.

如何使用数字检索相应的缩略图?

How can I use the number to retrieve the corresponding thumbnail?

谢谢

Jason

推荐答案

Hello Jason，

如果您的目标是Windows XP，那么本文( Pete Davis附带的C#源代码可能会帮助您.他的ThumbDBLib可以帮助您读取Windows XP缩略图缓存文件并提取项目图像.参见 http://www.petedavis.net/MySite/DynPageView.aspx?pageid=31 (这是第三方网站，不受Microsoft拥有或控制，我们为您提供方便的链接.使用此链接，后果自负.)

如果您的目标是Windows Vista或更高版本，则有一个不同的缩略图故事，您可能想看看 IThumbnailCache接口.

Hello Jason,

If you are targeting Windows XP, then this article (C# source code included) by Pete Davis may help you out. His ThumbDBLib can help you read the Windows XP thumbnail cache file and extract the item images. See http://www.petedavis.net/MySite/DynPageView.aspx?pageid=31 (This is a third party website which is not owned nor controlled by Microsoft, we provide the link for your convenience. Use it at your own risk.)

If you are targeting Windows Vista or later, which has a different thumbnail story, you may want to take a look at the IThumbnailCache Interface.
