wia - 相当于 WIA DeviceDlg 的 WPD

Question

我正在为当前使用 Windows Image Acquisition (WIA) 的应用程序添加 Windows 可移植设备 (WPD) 支持。 WIA 通过 IWiaItem::DeviceDlg 提供了一个方便的图片选择对话框。

我找不到 WPD 等效项。有没有，如果没有，允许用户选择项目的首选技术是什么？我不必自己编写对话，对吗？

[T]here is no dedicated dialog for picture selection (outside of WIA). Instead, you should use the regular file open dialog which supports WPD device navigation. There will be some magic that needs to be done to start the dialog at the correct folder within the device. You might have to write code to find the folder(s) with pictures.

The magic path to pass to the File Open dialog is: ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\<device instance id>

The device instance id can be derived from the PnP Device Path via SetupApi calls (SetupDi*).

Further, the above path can include additional path elements to identify a specific folder on the device. These are different for every device model, but would look something like: ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\\Store0\Pictures
