每次在运行 Windows 7 或 Windows Server 2008 R2 的系统上安装我的 Windows 服务(用 C# 开发,Visual Studio 2010)时,都会记录系统错误 7030。该服务未配置为交互式。我创建的自定义安装程序子类将帐户类型设置为 NetworkService:
private System.ServiceProcess.ServiceProcessInstaller _serviceProcessInstaller;
private System.ServiceProcess.ServiceInstaller _serviceInstaller;
public ProjectInstaller()
{
InitializeComponent();
}
private void InitializeComponent()
{
_serviceProcessInstaller = new System.ServiceProcess.ServiceProcessInstaller();
_serviceInstaller = new System.ServiceProcess.ServiceInstaller();
_serviceProcessInstaller.Account = System.ServiceProcess.ServiceAccount.NetworkService;
_serviceProcessInstaller.Password = null;
_serviceProcessInstaller.Username = null;
_serviceInstaller.ServiceName = Resources.ServiceName;
_serviceInstaller.Description = Resources.ServiceDescription;
_serviceInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic;
Installers.AddRange(new Installer[]
{
_serviceProcessInstaller,
_serviceInstaller
});
}
我也尝试将帐户类型设置为 LocalSystem,但在这种情况下也会记录错误 7030。
在同一个安装程序子类中,我还尝试根据如何在代码中配置我的 Windows 服务以访问桌面?:
/// <summary>
/// Override OnCommitted() to overwrite the value of Interactive to be false.
/// </summary>
/// <remarks>
/// See https://stackoverflow.com/questions/1945529/how-can-i-configure-my-windows-service-in-the-code-to-access-the-desktop
/// </remarks>
/// <param name="savedState"></param>
protected override void OnCommitted(System.Collections.IDictionary savedState)
{
const string pathToKey = @"SYSTEM\CurrentControlSet\services\MyService.exe";
const string type = "Type";
using (var registryKey = Registry.LocalMachine.OpenSubKey(pathToKey, true))
{
if (registryKey != null && registryKey.GetValue(type) != null)
{
registryKey.SetValue(type, (((int)registryKey.GetValue(type) & ~0x100)));
}
}
base.OnCommitted(savedState);
}
这两次修复尝试都没有奏效。我还在 SO 上查看了以下内容:“允许服务与桌面交互”的替代方案?以及如何在 Windows 服务安装程序中设置“与桌面交互”。
