Windows安全自定义登录验证自定义、安全、Windows
我创建的XAML / C＃应用程序，我想它弹出一个登录提示。
我想知道，如果它可能使用CredUIPromptForWindowsCredentials。
显示Windows安全对话框 获取输入的用户名和放大器;密码 执行自定义验证 如果验证更迭 - >继续应用 否则，如果验证失败 - >无效的用户名或密码的-inform用户我已经看了 Windows安全登录表单？和的http://www.pinvoke.net/default.aspx/credui/creduipromptforwindowscredentials.html?diff=y但他们没有说明如何处理验证。
我会很喜欢的一个小例子，在那里，如果用户输入的用户名=博和密码=123，然后更迭否则显示错误信息，并允许用户再试一次。
应用程序将被多台计算机上安装。
或者，这是根本不可能的？
更新
在这个问题的答案Show在C＃中使用Windows身份验证对话框Vista / 7的
我已经修改了code到正常工作。
请不，该验证部分仅用于概念验证。

解决方案
您会发现一个完全实现WPF和使用CredUIPromptForWindowsCredentials在的 Ookii对话框的。
I'm creating an Xaml/C# application and I would like it to popup with a Login Prompt.
I would like to know if its possible to use CredUIPromptForWindowsCredentials.
Show Windows Security Dialog Get the entered username & password Perform Custom validation If validation succes -> continue app else if validation failed -> -inform user of invalid username or passwordI have already looked at Windows Security login form? and http://www.pinvoke.net/default.aspx/credui/creduipromptforwindowscredentials.html?diff=y but they don't explain how to handle the validation.
I would really like a small example, where if the user enters username = "Bo" and password = "123" then succes else display error message and allow the user to try again.
The App is going to be installed on multiple computers.
Or is this simply not possible?
Update
Inspired by the answer in this question Show Authentication dialog in C# for windows Vista/7
I have modified the code to work as expected.
Please not, that the validation part is only for proof of concept.

解决方案
You'll find a complete implementation for WPF and WinForms using CredUIPromptForWindowsCredentials at Ookii dialogs.
