Starting and stopping a local windows service from web app.

Hi,

I created a asp.net web app as a config tool for a local service. I need to start/restart or stop this service from the web app. i build the next code and the web app is running in asp debug envirment of VS2010. But when i push the start button i get Cannot open ZRGSService service on computer '.'.

try

{

ServiceController[] scServices;

scServices =ServiceController.GetServices();

foreach (ServiceController scTemp in scServices)

{

if (scTemp.ServiceName == "ZRGSService")

{

Cell1.Text = (sc.Status.ToString());

Cell2.Text = (sc.CanPauseAndContinue.ToString());

Cell3.Text = (sc.CanShutdown.ToString());

Cell4.Text = (sc.CanStop.ToString());

Cell5.Text = (System.Security.Principal.WindowsIdentity.GetCurrent().Name);

and

protected void startbutton_Click(object sender, EventArgs e)

{

if (sc.Status == ServiceControllerStatus.Stopped)

{

sc.Start();

while (sc.Status == ServiceControllerStatus.Stopped)

{

Thread.Sleep(1000);

sc.Refresh();

}

System.InvalidOperationException was unhandled by user code Message=Cannot open ZRGSService service on computer '.'. Source=System.ServiceProcess StackTrace: at System.ServiceProcess.ServiceController.GetServiceHandle(Int32 desiredAccess) at System.ServiceProcess.ServiceController.Start(String[] args) at System.ServiceProcess.ServiceController.Start() at ZRGSWebConfig.Reboot.startbutton_Click(Object sender, EventArgs e) in C:\Users\W7x64\Documents\Visual Studio 2010\Projects\ZRGSWebConfig\ZRGSWebConfig\Customer pages\Reboot.aspx.cs:line 108 at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) InnerException: System.ComponentModel.Win32Exception Message=Toegang geweigerd ErrorCode=-2147467259 NativeErrorCode=5 InnerException:

My servicecontroller reads all the correct status info from the service.

Sorry Guys,

Re: Starting and stopping a local windows service from web app.

I think it's UAC problem:

Your application requires elevated user rights. That is why the "run as administrator" works outside of the IDE.

Some sites suggest disabling UAC. As this is not a possibility in my environment, I decided to request elevated user right via code. Wikipedia provided the help I needed. The "Requesting elevation" section provides the solution.

The solution in short:

Edit your application manifest file to reflect your requirement.

1.1. Right click your project
1.2. Click "Properties"
1.3. Select "Application" tab - default page
1.4. Click "View UAC Settings" - This button opens the application manifest file (app.manifest)
1.5. Look for the "UAC Manifest Options" section
1.6. Remove or comment the current entry - {requestedExecutionLevel level="asInvoker" uiAccess="false"}
1.7. Change to {requestedExecutionLevel level="requireAdministrator" uiAccess="false"}. MS provides your 3 options as part of the section comment.
