Windows凭据对话框克隆

• 下载source code - 48.7 KB

介绍 Windows证书对话框可以显示使用CredUIPromptForCredentials Win32 API调用。该方法提供的凭证对话提出了几个问题: 使用非托管代码。保存凭证存储在Windows凭证存储(不一定是坏的)。困难的实现为用户使用搜索功能的对话框。 我需要一个对话框,用户很熟悉,但也提供了相同的功能没有上述限制。这个对话框模仿Windows对话框的功能有一些额外的特性。 完全包含在托管代码。开发人员可以凭证保存在自己的商店,很容易管理。开发人员可以很容易地实现一个“搜索用户”函数将返回一个用户名称对话框。 使用的代码 对话框中被实现为一个组件,可以直接添加一个表单。当补充道,一些属性和事件暴露控制对话框的功能。 属性和事件 ApplicationNameStringGets或设置应用程序的名称。CustomBitmapImageGets或设置自定义位图(320 x57)。DescriptionStringGets或设置描述。EnableSearchForUserBooleanIndicates搜索用户按钮是否启用。RememberCheckboxCheckedBooleanIndicates显示记得复选框是否选中。ShowRememberCheckboxBooleanIndicates是否记住密码复选框显示。 还有各种事件,可用于提供我需要的额外特性。 QuerySearchForUserOccurs当用户单击搜索用户按钮。返回用户名中选择事件参数。QueryPreviouslyUsedUsernamesOccurs当对话框显示你可以供应之前使用登录名称的列表。返回之前用户名用于事件的参数列表。QueryInitialCredentialsOccurs当对话框显示之前你可以供应使用凭证。返回用户名和密码用于事件参数。SaveCredentialsOccurs当用户单击OK按钮,SavePassword复选框选中的凭证可以保存。 例子 下降后LoginDialog形式和设置相关属性,显示对话框如下: 隐藏,收缩,复制Code
