我有一个使用C#在VS2010中编写的Windows窗体应用程序,并在app.config文件中获得以下错误:

Message 4   Could not find schema information for the attribute 'name'

背景:我的老板尝试使用公共和私有部分向我输出ASC密钥,但每当我收到文件时,私有部分永远不会加载,它不会解密任何文件.

我们尝试使用以下方法导出ASC密钥:

• Windows应用程序Kleopatra 2.1(包含在gpg4win中)

• Windows应用程序GNU隐私助手(包含在gpg4win中)

          Error: "Decryption failed. Secret Key Not available." 
  

  Run Code Online (Sandbox Code Playgroud)

如何正确导出秘密或私有asc密钥来解密gpg文件？

我正在创建一个基于旧项目的项目,因为它具有我需要使用的许多功能.我想重命名所有目录和解决方案名称以获得新项目的名称.在Documents\Visual Studio 2008\Projects下,我能够更改初始目录和解决方案文件名,但不能更改包含bin,obj和properties文件夹的子目录的名称.当我更改该子目录的名称时,打开解决方案时将不会打开任何文件.

如何在VS2008中更改项目的文件夹名称,以便它将所有文件作为解决方案的一部分加载并仍然有效？

是否存在可以根据文本框宽度显示路径的智能文本框控件(WinForms).例如,如果路径很短,它将显示整个路径(C:\ myfile.txt),但如果路径很长,它将显示开始和结束(C:\ SomeFolder ...\foo\MyFile.txt ).显示的字符长度应由文本框使用其宽度(动态)计算.欢迎任何商业或开源建议.非常感谢你.

使用VB.NET,如何使用Active Directory将sid转换为组名？

例如:我需要获得"group_test"而不是"S-1-5-32-544"

我正在使用的代码是:

Public ReadOnly Property Groups As IdentityReferenceCollection
    Get

        Dim irc As IdentityReferenceCollection
        Dim ir As IdentityReference
        irc = WindowsIdentity.GetCurrent().Groups
        Dim strGroupName As String

        For Each ir In irc
            Dim mktGroup As IdentityReference = ir.Translate(GetType(NTAccount))
            MsgBox(mktGroup.Value)
            Debug.WriteLine(mktGroup.Value)
            strGroupName = mktGroup.Value.ToString

        Next

        Return irc

    End Get
End Property

或类似的东西？

        currentUser = WindowsIdentity.GetCurrent()

        For Each refGroup As IdentityReference In currentUser.Groups

            Dim acc As NTAccount = TryCast(refGroup.Translate(GetType(NTAccount)), NTAccount)
            If AdminGroupName = acc.Value Then
                ret = "999"
            End If
            If UsersGroupName = …

背景:在部署在本地计算机上无错误编译的应用程序后,我收到内部服务器500 24 50错误.部署应用程序的服务器具有大量安全性并且运行IIS 7.5,因此我需要为每个目录指定读写访问权限.此应用程序使用Windows身份验证和Web服务通过代理填充下拉框.我认为连接到Web服务可能存在问题,或者文件的读/写安全性问题,或者活动目录身份验证存在问题.

由于某种原因,Internet Explorer刚刚显示无法加载网页错误.

Google Chrome中出错:

不幸的是,我在网上找到的自定义角色和成员提供商背后的表单身份验证代码的所有示例都是用VB.NET代码编写的,我需要一个C#代码.请帮忙!!!!

我需要一个代码隐藏,它将执行以下操作:

• 登录按钮单击后验证用户
• if user active_flag = 0(false)OR password!= @ password,显示错误:"Access Denied"
• 如果用户admin_flag = 1&active flag = 1(true),则重定向到admin_pages\zipsearch.aspx
• 如果用户admin_flag = 0(false)&active_flag = 1(true),则重定向到pages\zipsearch.aspx

Default.aspx代码:

    <asp:Login ID="LoginUser" runat="server" EnableViewState="false" RenderOuterTable="false">
    <LayoutTemplate>
        <span class="failureNotification">
            <asp:Literal ID="FailureText" runat="server"></asp:Literal>
        </span>
        <asp:ValidationSummary ID="LoginUserValidationSummary" runat="server" CssClass="failureNotification"

        <div class="accountInfo">
