get image from scanner
提问by Ovi
How do you get a image from the scanner using .NET (C#) on Vista? Preferably to have the possibility to set the DPI.
如何在 Vista 上使用 .NET (C#) 从扫描仪获取图像？最好有可能设置 DPI。
There are a few controls on the market that do this, but they don't seem to work very well.
市场上有一些控件可以执行此操作，但它们似乎效果不佳。

You can P/Invoke into twain_32.dll, like with the CodeProject sample at http://www.codeproject.com/KB/dotnet/twaindotnet.aspx.
您可以 P/Invoke 进入 twain_32.dll，就像http://www.codeproject.com/KB/dotnet/twaindotnet.aspx上的 CodeProject 示例一样。
There's also Window Image Aquisition automation in wiaaut.dll, for which you get an automatically-generated wrapper as in the Coding4Fun sample at http://blogs.msdn.com/coding4fun/archive/2006/10/31/912546.aspx
wiaaut.dll 中还有 Window Image Aquisition 自动化，为此您可以获得一个自动生成的包装器，如http://blogs.msdn.com/coding4fun/archive/2006/10/31/912546.aspx 上的 Coding4Fun 示例
