I have a port monitor dll, that I instaling by call AddMonitor function of the spooler. But when I want uninstal this monitor, the DeleteMonitor function return errorcode 3008 - "The specified print monitor is currently in use". How I can free my monitor dll?

private class MONITOR_INFO_2
{

public string pName;

mi2.pEnvironment = null;
mi2.pDLLName = dllName;
try
{
bool bRet = AddMonitor(null, 2, mi2);
if (!bRet)
throw new Win32Exception(Marshal.GetLastWin32Error());
}
catch (Exception e)
{
if (!DeleteMonitor(null, null, monitorName))
{
throw new Win32Exception(Marshal.GetLastWin32Error());
}
bRet = AddMonitor(null, 2, mi2);
if (!bRet)
throw new Win32Exception(Marshal.GetLastWin32Error());
}
}
You will not be able to Delete a Port Monitor via the DeleteMonitor call if there is one or more printer objects currently using a port of that type.
This leaves you with several options:
Swap the port of all affected printers to another port. (Best to use something like LPT1: since its always there).
Delete all printers using the port.
Stop the spooler service and remove the appropriate entries from registry (HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors) then restart the spooler. This will leave the affected printers there but they will be unusable.

My understanding is that IModel instances are reasonably cheap to create and that's what I started with. I was creating a separate IModel for each class that was ever using it: each Application Service class gets its own IModel, as does every Controller. It was working fine, but having 30+ channels open was a bit worrisome.
I thought about serializing access to a shared IModel:
lock(publisherLock)
publisherModel.BasicPublish(...);
but now there's a point of contention for no good reason.
So, what will be the correct way of publishing messages into a RabbitMQ exchange from an ASP.NET MVC application?
What you must not do is allow a channel to be used by more than one thread, so keeping channels open over several requests is a bad idea.
IModel instances are cheap to create, but not free, so there are a couple of approaches you can take:
The safest thing to do is simply to create a channel each time you want to publish and close it again straight away. Something like this:
using(var model = connection.CreateModel())
{
var properties = model.CreateBasicProperties();
model.BasicPublish(exchange, routingKey, properties, msg);
}
You can keep the connection open for the lifetime of the application, but be sure to detect if you loose the connection and have code to reconnect.
The downside with this approach is that you have the overhead of creating a channel for each publish.
The alternative is to hold a channel open on a dedicated publishing thread and marshal all your publish calls onto that thread using a BlockingCollection or similar. This will be more efficient, but more complex to implement.
Here is something which you can use,
BrokerHelper.Publish("Aplan chaplam, chaliye aai mein :P");
and below is the defination for the BrokerHelper class.
public static class BrokerHelper
{
public static string Username = "guest";
public static string Password = "guest";
public static string VirtualHost = "/";
// "localhost" if rabbitMq is installed on the same server,
// else enter the ip address of the server where it is installed.

var encodedMessage = Encoding.ASCII.GetBytes(message);
Channel.BasicPublish(ExchangeName, RoutingKey, null, encodedMessage);

final String name = lpBuffer.getString(0);
System.out.println("value of 'lpBuffer'：" + name);
Assert.assertEquals(THIS_PC_NAME, name);
}
}
The offical instructions says use byte[]、char[]、Memory or NIO Buffer for mapping char pointer in c native function.But I tried all of above, and String、WString、StringArrays、class extends PointType etc, all of them are no use.
Out parameter 'lpnSize' can return the corret buffer size，but 'lpBuffer' return 'x>'(i think it's random memory) or nothing no matter I mapping any java type.If i wrote someting to the 'lpBuffer' memory first, it would read the same things after calling native function.
How can I solve the problem?
You need to use Pointer.getString(0, true) to extract the unicode string returned by GetComputerNameW.
EDIT
You'll also need to call GetComputerNameW again with the length parameter initialized before the function will fill in the result. Either pass back the same IntByReference to a second call, or initialize the IntByReference to the size of your Memory buffer to have the buffer written to in the first call.
I have to write a standalone Java app that monitors CQ5, deployed inside Weblogic (especially memory usage).
I was able to connect to the Domain Runtime Server in weblogic, using the class below (as found in the docs).

Can any of you give me some insight? This is a pure JMX / Java question, unrelated to CQ.

I'm trying to print XPS documents from a windows service on the .net framework. Since Microsoft does not support printing by using System.Drawing.Printing nor by using System.Printing (WPF), I'm using the native XPSPrint API.
This is suggested to me by Aspose in http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/howto-print-a-document-on-a-server-via-the-xpsprint-api.html.
When I try to print an XPS document from a windows service, the result contains strange characters instead of the text I want.
I tried with different printers (including virtual printers like for instance PDFCreator), different users and user-privileges for the service, different xps generators (aspose, word 2007, word 2010), different platforms (windows 7, windows 2008 R2) but all have the same result.
Does anybody knows how to solve this? Any help would be appreciated!
For those who want to try it, I shared some files via:

I talked with microsoft about this issue and we discovered the problem is related to incorrect font substitution in the printer-spooler. When the printer is set to not spool the documents, they are printed correctly, also from a windows service. Otherwise, all fonts, except arial (and maybe some others), are substituted by another font. In the sample I provided, calibri is substituted by wingdings.
So, they acknowledge this to be a bug but at the moment they will not resolve it. It will depend on how many people will suffer from this bug in order for them to decide whether are not they are willing to fix it...
I want to write a console or Click Once WinForms app that will programmatically stop and/or start a windows service on a remote box.
Both boxes are running .NET 3.5 - what .NET API's are available to accomplish this?
in C#:
var sc = new System.ServiceProcess.ServiceController("MyService", "MyRemoteMachine");
sc.Start();
sc.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Running);
sc.Stop();
sc.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped);
You can also do this from a command console using the sc command:
sc <server> start [service name]
sc <server> stop [service name]
Use
sc <server> query | find "SERVICE_NAME"
to get a list of service names.
The option <server> has the form \\ServerName
Example
sc \\MyServer stop schedule will stop the Scheduler service.
ServiceController.
You need to have permission to administer the services on the remote box.
As Mehrdad says, you can also use WMI. Both methods work for start and stop, but WMI requires more coding and will give you more access to other resources
If you don't want to code it yourself, PsService by Microsoft/Sysinternals is a command line tool that does what you want.
You can use System.Management APIs (WMI) to control services remotely. WMI is the generic API to do administrative tasks.
For this problem, however, I suggest you to use the easier to use System.ServiceProcess.ServiceController class.
if you need to get the name of the Service:
run this from the command line:
sc query
You will see for example, that SQL Server's service name is 'MSSQL$SQLEXPRESS'.
So to stop the SQL Server service in C#:
ServiceController controller = new ServiceController();
controller.MachineName = "Machine1";
controller.ServiceName = "MSSQL$SQLEXPRESS";
if(controller.Status == ServiceControllerStatus.Running)
controller.Stop();
controller.WaitForStatus(ServiceControllerStatus.Stopped);
galets code snippet above is a great start. However, keep in mind it assumes that the service has already started, or, more importantly, that
sc.Status == System.ServiceProcess.ServiceControllerStatus.Running
Also, it may important to, at some point during code execution, call
sc.Refresh();
because the properties values (such as ServiceControllerStatus) may not reflect the actual properties of the service.
For instance, you may call
sc.Start();
and wait indefinitely when this command executes
sc.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Running)
Here is a version of this code that I coded with those considerations in mind.
//Restart Content Service on DEV.
String svcName = "TheServiceName";
String machineName = "TheMachineName";
var sc = new System.ServiceProcess.ServiceController(svcName, machineName);
Console.WriteLine("Stopping Service '{0}' on machine '{1}", svcName, machineName);
sc.Stop();
sc.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped);
//sc.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Running);
do
{
try
{
sc.Refresh();
if (sc.Status == System.ServiceProcess.ServiceControllerStatus.Running)
{
Console.WriteLine("Code has detected that servive start is pending, waiting 5 seconds to see if status changes..");
System.Threading.Thread.Sleep(5000);
}
else
{
Console.WriteLine("waiting 5 seconds and retrying start..");
System.Threading.Thread.Sleep(5000);
Console.WriteLine("Attempt Starting Service '{0}' on machine '{1}", svcName, machineName);
sc.Start();
}
}
catch(Exception ex)
{
//If it is already running, then abort do while
if (ex.InnerException.Message == "An instance of the service is already running")
{
Console.WriteLine(ex.InnerException.Message);
continue;
}
Console.WriteLine(ex.InnerException.ToString());
}
} while (sc.Status != System.ServiceProcess.ServiceControllerStatus.Running);
I have done like below:
Note:
If you didn't start your service if you are trying to stop it will throw exception.
If you configure these things in your web.config ,configuration related exception will not come. No need to do anything in IIS.
In Web.Config under <configuration>
<appSettings>
<add key="ServiceName" value="YourServiceName" />
<add key="MachineName" value="YourMachineName" />
</appSettings>
<system.web>
<authentication mode="Windows"/>
<identity impersonate="true" userName="YourUserName" password="YourPassword"/>
</system.web>
In My Service Class:
private void RestartService()
{
string serviceName = System.Configuration.ConfigurationSettings.AppSettings["ServiceName"];
string machineName = System.Configuration.ConfigurationSettings.AppSettings["MachineName"];
try
{
var service = new ServiceController(serviceName, machineName);
if (service.Status != ServiceControllerStatus.Stopped)
{
service.Stop();
service.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped);
}
service.Start();
service.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Running);
}
catch (Exception)
{
}
}
Hope this Helps.

You can start a service like this
using System.ServiceProcess;
serviceName = "the name of the service"
machineName = "the name of the remote/local host"
var service = new ServiceController(serviceName, machineName);
try
{
service.SetStartMode(ServiceStartModeEx.DelayedAutomatic);
service.Start();
}
finally
{
service.Close();
}
You can stop a service like this
var service = new ServiceController(serviceName, machineName);
try
{
if (service.CanStop)
{
service.SetStartMode(ServiceStartModeEx.Disabled);
service.Stop();
}
}
finally
{
service.Close();
}
To grant a user rights to start and stop a service on a remote pc you have to set some service rights, you can google what subinacl.exe is and where to download it.
C:\Program Files (x86)\Windows Resource Kits\Tools>subinacl.exe /service SERVICENAME /grant=MACHINENAME\USERNAME=F
