带有 ASP.NET 网站的 Secugen 指纹扫描仪

Question

我一直致力于将 Secugen 指纹读取器和 API 实现到一个 ASP.NET 网站中，用于无家可归者收容所，这让我发疯了。我正在使用适用于 Windows API 的 FDx SDK Pro，并且我有自定义 COM 组件（通过 OCX 文件）将 activeX 控件导入我的工具箱。但是，这些控件只能在我创建 Windows 应用程序然后创建 Windows 窗体时使用。我需要在 Web 表单中包含这些控件。如果我尝试将它们放在网络表单中，activeX 工具将显示为灰色，并且不允许我这样做。 .htm 有一个例子，它完全符合我的要求，所以我知道这是可能的，但我就是不知道依赖项是什么。我只是不熟悉 .NET 和程序集库。这是 API 附带的自述文件，其中包含它拥有的不同文件。我不确定是否必须先创建一个 Windows 窗体，然后将其作为对象放入我的网站。我试图将“SecuGen.FdxSdkPro.Windows.dll”文件放入我的 bin 文件夹中，但是当我运行它时，当我运行它时出现以下错误。任何输入都将不胜感激，如果上传 .htm 示例或提供代码有什么用处，请告诉我。

Answer 1

确保您的应用程序是在 32 位平台目标中构建的

Answer 2

我不小心有两个帐户。首先是肯定的，您必须确保将 SDK 安装在正确的位服务器上。我最终采用了 active-x 控件并将它们嵌入到 Web 表单中。然后当指纹被捕获并将其转换为通过ajax发送到服务器的字符串。

然后我遇到了一个问题，即 SDK 没有正确解密字符串以进行比较的功能。我联系了 Secugen，他们非常乐意将我的请求提交给工程师，然后工程师向我提供了另一个包含缺失功能的 .dll 文件。有一天，我可能会在 GitHub 上发布一些源代码。当我这样做时，我会用链接更新这个！

Answer 3

如果您在 Windows 应用程序中遇到此问题，尤其是在生产环境中，请检查是否安装了 microsoft c++ redistributable。必须安装 2015 才能正常工作。
