Can someone please just show me what to and help me understand why that example code might be resulting in no image? (Also, I would be far more extremely grateful for explanations and code samples than I would be for links movie thumbnailer (mtn) - saves thumbnails (screenshots) of movie or video files to jpeg files. Stack overflow have mentioned using IShellImageItemFactory, but again, there are no examples anywhere on how to implement this and actually use it in my code. I figured maybe that part of the code just doesn't work in Windows 7, but I don't know what else to try. I got the farthest when I tried doing something like the following (see the code towards the end of the article.Code Listing 1).īut the image I end up extracting is null, even if I can go to Windows explorer and see that the file has a perfectly good thumbnail. Adobe Systems has lowered a barrier to using its Digital Negative (DNG) format, releasing an early version of software that makes it possible to see image thumbnails in 64-bit Windows. In the Advanced Settings list, put a checkmark beside Always show icons, never. (You can also launch these options in File Explorer by clicking on View > Options in the menu bar.) In the File Explorer Options window, click on the View tab. They're part of the code archive that no longer exists. Open the Start menu and type File Explorer Options. (For example, I see IThumbnailProvider being thrown around alot on various forums, but there is absolutely no example anywhere that I've found on how to actually use it to get a thumbnail.) And whenever microsoft pages link to supposed examples, The other problem is that there are no examples anywhere of how to implement the interfaces that will supposedly allow me to get My first problem is that I'm unclear what methods work for Windows 7, since apparently the thumbnail cache works differently. All I want to do is obtain the preview thumbnails for things like images and avi files - basically the kind you'd see in Windows explorer if you set the view to show medium/large/extra large icons for the files, so I can drawn them in my I am working on an app in Windows 7 (using visualĬ++, mfc). I've been looking everywhere for an answer to what I feel should be a very simple question, but I can't find any code examples or MSDN articles or library pages that have gotten me anywhere.
