How to be allowed to start/stop windows service via ASP.NET page

Hi,

I have a website with a Page that can start or stop a Windows Service. I get the error:
Cannot open Service Control Manager on computer 'NZDB-TST'. This operation might require other privileges.

My code:

private void RunAlongServices(String ServiceName)
{

    // Nog wel machinenaan aanpassen!!!
    ServiceController ctrl = new ServiceController(ServiceName, "NZDB-TST");

    if (ctrl.Status.Equals(ServiceControllerStatus.Stopped))
    {
        ctrl.Start();
    }
    else
    {
        ctrl.Stop();
    }
}

How to solve this issue, so the Windows service(s) can be started or stopped via de website?

It appears you need to effect a change in privileges some way. What do you think the odds are that Microsoft has documented Privilege issues associated to using ServiceController? I guess those are pretty good odds. I also guess a simple Google search using the keyword MSDN along with other key words in your original post would turn up that documentation.

Of course I am just guessing. Good luck.

asp.net runs under IUser_machine_name account. Do you think it has permission to run services?

Why do you want to start/stop service from asp.net anyway? Can't you solve it using other ways?

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Hello Yusuf,

the reason I want this done via a website is to givethe real administrator of the website I am creating the possibility to control the services from the website.
If it can be done indirectly with a command via the website it is allright too. So, do you know any better options?

So are you targeting website administrators? what does web admin has to do with windows services?

why? again I fail to see why web admin needs to interact with windows services.

Windows services are meant to be running in the background on the server. Why do your application need to start/stop services. If there is a service your web app needs to interact, then make sure it is running. If needed you can change its properties from Services windows.

If this is a windows service you wrote for the web application, then let it run automatically all the time. Alternatively, move the code to your code behind or write an assembly.

If the target audience is Server Administrators then they need to remote login and perform what ever they want.

We use a method for this functionality

static public String GetClientIP(Page page)
    {
        //Find the users own IP
        String strIpAddress = String.Empty;
        try
        {
            strIpAddress = page.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (strIpAddress == null)
                strIpAddress = page.Request.ServerVariables["REMOTE_ADDR"];
            if (strIpAddress == null)
                strIpAddress = page.Request.UserHostAddress;
        }
        catch 
        {
            strIpAddress = "IP address not found";
        }
        return strIpAddress;
    }

DataTable have method Select() and try to use that method to filter your data with every 10 rows.
In your Next button filter data with next 10 rows based on last row of current result,in Previos button filter data with 10 previous rows based on current data result.

Or you can use Paging property of GridView

yes when ever selected value of dropdown is changed the event selected index changed is called if ispost back property of dropdown list is set to true.

or you can check it on client side also without postback.

Here is an example of how it can be done. On the main page i have a label that reads the value of the dropdownlist and once the dropdownlist updates it re-populates the label.

the main page

<asp:label id="Label1" runat="server" xmlns:asp="#unknown"></asp:label><br />
    <asp:dropdownlist id="DropDownList1" autopostback="true" runat="server" xmlns:asp="#unknown">
    <asp:listitem value="Update1">Update1</asp:listitem>
    <asp:listitem value="Update2">Update2</asp:listitem></asp:dropdownlist>

and the code behind

protected void Page_Load(object sender, EventArgs e)
     {
         Label1.Text = DropDownList1.SelectedValue;

     }

This is a quick example just to point you in the right direction. Hope it helps.

Page take long time to load due to heavy files(mainly .axd files).I am using few server side controls(textBox,dropdownlist,button and updatePanel).
I want to minimize the size of .axd files which contribute most to the total size(including .css,.js,images).I have set the scriptMode to "release".
<scriptmanager id="scriptManager" runat="server" scriptmode="release">
But didn't gain much.
I also have set the debug="true" in web.config file.
<compilation debug="true">

If you want to send mail using Web Service then who will going to initiate the Web service call on time interval ?

You can thing about Windows Service which will call your service to send mail on time interval. You have to scheduled it / Or use TimerCallBack in winservice to Call web service method on specific time.

If web service is only for send mail then you can do it directly from Windows service also.

Let me know if any issue.
