方法一：

在ProjectInstaller.cs重寫 install() ,Uninstall()方法

public override void Install(IDictionary stateServer)
??{
???Microsoft.Win32.RegistryKey system,
????//HKEY_LOCAL_MACHINE\Services\CurrentControlSet
????currentControlSet,
????//...\Services
????services,
????//...\<Service Name>
????service,
????//...\Parameters - this is where you can put service-specific configuration
????config;

???try
???{
????//Let the project installer do its job
????base.Install(stateServer);

????//Open the HKEY_LOCAL_MACHINE\SYSTEM key
????system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System");
????//Open CurrentControlSet
????currentControlSet = system.OpenSubKey("CurrentControlSet");
????//Go to the services key
????services = currentControlSet.OpenSubKey("Services");
????//Open the key for your service, and allow writing
????service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true);
????//Add your service's description as a REG_SZ value named "Description"
????service.SetValue("Description","PI實時數據采集：能源--每天8點或20點取一次數據；汽車衡--每天1點取一次數據；設備狀態--每分鐘取一次數據。");
????//(Optional) Add some custom information your service will use...
????//允許服務與桌面交互
????service.SetValue("Type",0x00000110);
????config = service.CreateSubKey("Parameters");
???}
???catch(Exception e)
???{
????Console.WriteLine("An exception was thrown during service installation:\n" + e.ToString());
???}
??}

??public override void Uninstall(IDictionary stateServer)
??{
???Microsoft.Win32.RegistryKey system,
????currentControlSet,
????services,
????service;

???try
???{
????//Drill down to the service key and open it with write permission
????system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System");
????currentControlSet = system.OpenSubKey("CurrentControlSet");
????services = currentControlSet.OpenSubKey("Services");
????service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true);
????//Delete any keys you created during installation (or that your service created)
????service.DeleteSubKeyTree("Parameters");
????//...
???}
???catch(Exception e)
???{
????Console.WriteLine("Exception encountered while uninstalling service:\n" + e.ToString());
???}
???finally
???{
????//Let the project installer do its job
????base.Uninstall(stateServer);
???}
??}

方法二：
此方法經測試，發現無效，勾是選上了，但程序啟動后還是沒有界面出現，好像需要電腦重啟才生效

我們寫一個服務，有時候要讓服務啟動某個應用程序，就要修改服務的屬性，勾選允許服務與桌面交互，

可以用修改注冊表實現，我們必須在安裝后操作，所以請重寫Installer的OnAfterInstall。

?

protected override void OnAfterInstall(System.Collections.IDictionary savedState) {
RegistryKey rk = Registry.LocalMachine;
string key = @"SYSTEM\CurrentControlSet\Services\" + this.sInstaller.ServiceName;
RegistryKey sub = rk.OpenSubKey(key, true);
int value = (int)sub.GetValue("Type");
if (value < 256) {
sub.SetValue("Type", value | 256);
}
base.OnAfterInstall(savedState);
}
onstart的時候修改注冊表???
?? [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\你的服務名]???
?? "Type"=dword:00000010???
?? key??? value＋256???
?? 比如現在00000010是16＋256＝272???
?? 16進制就是00000110?
方法三：
使用System.ServiceProcess.ServiceController
??????????? ConnectionOptions coOptions = new ConnectionOptions();
??????????? coOptions.Impersonation = ImpersonationLevel.Impersonate;
??????????? ManagementScope mgmtScope = new System.Management.ManagementScope(@"root\CIMV2", coOptions);
??????????? mgmtScope.Connect();
??????????? ManagementObject wmiService;
??????????? wmiService = new ManagementObject("Win32_Service.Name='" + ServiceController.ServiceName + "'");
??????????? ManagementBaseObject InParam = wmiService.GetMethodParameters("Change");
??????????? InParam["DesktopInteract"] = true;
??????????? ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null);
??????????? ServiceController.Start();

描述：在自己寫的一個系統服務程序，需要經常用到“允許與桌面進行交互”的設置，網上很多使用修改注冊表的形式實現，我測試過，修改注冊表后，選中的勾是選上了，

但不能彈出應用程序；據說重啟電腦后可以，但我不想重啟，實際應用也不允許重啟，故沒有測試重啟是否可行的情況。如圖：

?

?

例如：

當我需要運行服務程序的時候，彈出我的應用程序，則要在Windows服務“允許服務與桌面交互”中打勾，

當我不想彈出應用程序界面的時候，則去掉其中的勾選。

實現方式：

1.在服務程序安裝時編程實現，ProjectInstaller.cs

using?System;
using?System.Collections;
using?System.Collections.Generic;
using?System.ComponentModel;
using?System.Configuration.Install;
//using?System.Linq;
using?Microsoft.Win32;?//對注冊表操作一定要引用這個命名空間
namespace?MonitorService
{
????[RunInstaller(true)]
????public?partial?class?ProjectInstaller?:?Installer
????{
????????public?ProjectInstaller()
????????{
????????????InitializeComponent();????????????
????????????//this.Context.Parameters["ServerCode"].ToString();?//?讀取安裝時輸入的服務器編號???????????
????????}
????????private?void?ProjectInstaller_AfterInstall(object?sender,?InstallEventArgs?e)
????????{
????????????//設置允許服務與桌面交互
????????????SetServiceTable("MonitorService");????????????
????????}
????????///?<summary>
????????///?設置允許服務與桌面交互?,修改了注冊表，要重啟系統才能生效
????????///?</summary>
????????///?<param?name="ServiceName">服務程序名稱</param>
????????private?void?SetServiceTable(string?ServiceName)
????????{
????????????RegistryKey?rk?=?Registry.LocalMachine;
????????????string?key?=?@"SYSTEM\CurrentControlSet\Services\"?+?ServiceName;
????????????RegistryKey?sub?=?rk.OpenSubKey(key,?true);
????????????int?value?=?(int)sub.GetValue("Type");
????????????sub.SetValue("Type",?value?|?256);
????????}
????}
}

2.注冊表修改

onstart的時候修改注冊表???
???[HKEY_LOCAL_MACHINE"SYSTEM"CurrentControlSet"Services"你的服務名]???
???"Type"=dword:00000010???
???key????value＋256???
???比如現在00000010是16＋256＝272???
???16精制就是00000110
?

3.SC程序修改， 允許與桌面進行交互

?在dos命令提示符下輸入：
sc config MonitorService type= interact type= own

?回車即可。

可以用批處理的方式實現，把下面代碼保存為 myservice.bat 即可：

?rem 配置服務程序為允許與桌面進行交互方式
@echo "準備停止服務程序..."
sc stop MyService
@echo "設置允許與桌面進行交互方式允許"
sc config MyService type= interact type= own
@echo "正在重新啟動服務..."
sc start MyService
@echo "啟動服務成功！"

取消“允許與桌面進行交互”

DOS命令提示符下運行下面語句即可：

?sc config MyService type= own

經測試：1，2 可以選中“允許與桌面進行交互”，但啟動服務的時候，不能彈出應用程序的界面。

?????????? 3 可以完美實現所有要求。

至此，我遇到的問題也完美的得到解決。

用VS2003部署，讓服務程序安裝完后立即啟動服務并且選中“允許服務與桌面交互”及添加服務描述的方法

?

private?void?serviceInstaller1_AfterInstall(object?sender,?System.Configuration.Install.InstallEventArgs?e)???

}???
}???
//----------------------------?結束?----------------------------???

四、這一服務程序運行時沒有圖形界面？

不錯，剛才直接運行mfc1.exe時我們看到了圖形界面，但在服務列表中用右鍵菜單中的“啟動”時卻看不到任何界面。這該怎么辦？

我們還需要在使用CreateService函數時(Install()中)，加上一個參數，這樣才能允許程序與桌面交互，也就是可以顯示界面。這個參數是SERVICE_INTERACTIVE_PROCESS。

填加后的CreateService：

　　SC_HANDLE hService = ::CreateService(
　　　　 hSCM, m_szServiceName, m_szServiceName,
　　　　 SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS,
　　　　 SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
　　　　 szFilePath, NULL, NULL, _T("RPCSS"), NULL, NULL);

　　
再次編譯mfc1，卸載服務后，安裝服務。我們可以看到，通過服務列表啟動mfc1，原有的對話框出現了。

如需將服務設為自動啟動，則將 SERVICE_DEMAND_START 改為 SERVICE_AUTO_START。
