问题描述
我正在尝试建立一个使用TWAIN的C#应用程序代码项目示例
I'm trying to set up a C# application which uses TWAIN example from code project
除了我需要将Form强制转换为IMessageFilter并且调用IMessageFilter.PreFilterMessage()捕获TWAIN回调.
另外，我还需要通过调用
This works fine except that I need to cast Form to IMessageFilter and call IMessageFilter.PreFilterMessage() to catch TWAIN callbacks.
Also I need to start this filtering by calling
Application.AddMessageFilter();
是否可以在WPF窗口中执行相同的操作? (添加消息过滤器并捕获TWAIN回调).
Is there a way to do same thing in WPF Window? (To add message filter and catch TWAIN callbacks).
另一个完全高级的问题:有人知道替代的C#TWAIN库\包装器吗?
Another totally high level question:Does anybody know about alternative C# TWAIN libraries\wrappers?
谢谢.
推荐答案
您可以通过ComponentDispatcher.ThreadFilterMessage事件进行尝试.
据我了解，它在 WPF中具有相同的作用在 WinForms 中作为Application.AddMessageFilter().
You could try it with the ComponentDispatcher.ThreadFilterMessage event.
As far as I understand, it serves the same purpose in WPF as Application.AddMessageFilter() in WinForms.
