  • How to remotely control a Windows Service with ServiceController?

    - by Amokrane
    Hi, I'm trying to control Windows Services that are installed in a remote computer. I'm using the ServiceController class. I have this: ServiceController svc = new ServiceController("MyWindowsService", "COMPUTER_NAME"); With this, I can get the status of the Windows Service like this: string status = svc.Status.ToString(); But I can't control the Windows Service (by doing svc.Start(); or svc.Stop();). I get the following exception: Cannot open Servicexxx service on computer 'COMPUTER_NAME' That's normal, I suppose there is something to do with access permissions. But how? I've looked into Google but didn't find what I was looking for. However I often read something related to impersonation, but I don't know what that means. NB: The local and remote computers are both running Win XP Pro. Thanks.

  • Python encoding for pipe.communicate

    - by Brian M. Hunt
    I'm calling pipe.communicate from Python's subprocess module from Python 2.6. I get the following error from this code: from subprocess import Popen pipe = Popen(cwd) pipe.communicate( data ) For an arbitrary cwd, and where data that contains unicode (specifically 0xE9): Exec. exception: 'ascii' codec can't encode character u'\xe9' in position 507: ordinal not in range(128) Traceback (most recent call last): ... stdout, stderr = pipe.communicate( data ) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 671, in communicate return self._communicate(input) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1177, in _communicate bytes_written = os.write(self.stdin.fileno(), chunk) This is happening, I presume, because pipe.communicate() is expecting ASCII encoded string, but data is unicode. Is this the problem I'm encountering, and i sthere a way to pass unicode to pipe.communicate()? Thank you for reading! Brian

  • fd.seek() IOError: [Errno 22] Invalid argument

    - by Julian Kessel
    My Python Interpreter (v2.6.5) raises the above error in the following codepart: fd = open("some_filename", "r") fd.seek(-2, os.SEEK_END) #same happens if you exchange the second arg. w/ 2 data=fd.read(2); last call is fd.seek() Traceback (most recent call last): File "bot.py", line 250, in <module> fd.seek(iterator, os.SEEK_END); IOError: [Errno 22] Invalid argument The strange thing with this is that the exception occurs just when executing my entire code, not if only the specific part with the file opening. At the runtime of this part of code, the opened file definitely exists, disk is not full, the variable "iterator" contains a correct value like in the first codeblock. What could be my mistake? Thanks in advance

  • Android: Enable selection in webkit

    - by tacone
    Hello, I'am looking for a way to have a webview content selectable in the very same way as the stock browser does. user long presses the text the whole word is selected two pins appear at the word's boundary allowing the user to stretch/shrink the selection. I should note that Dolphin HD shows exactly the same text select functionality as the default browser (same icons, animation, etc), so it really should be possible. But I can't figure out how. Until now, all i found was this function, which kind of work, but doesn't allow the user to expand/shrink the selection. public void selectAndCopyText() { try { KeyEvent shiftPressEvent = new KeyEvent(0,0,KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0); shiftPressEvent.dispatch(mWebView); } catch (Exception e) { throw new AssertionError(e); } }

  • Custom Validation on jquery validate plugin, need to count element in a multiple select

    - by 0plus1
    I have a multiple select, and I need to force the user to choose maximum two options, nothing more. I'm trying this: jQuery.validator.addMethod("morethantwo", function(value, element) { var foo = []; $(element+' :selected').each(function(i, selected){ foo[i] = $(selected).text(); alert(foo[i]); }); return true; },"Max two options." ); The problem is that I get a: uncaught exception: Syntax error, unrecognized expression: [object HTMLSelectElement] error. While if I do this: $(element).each(function(i, selected){ foo[i] = $(selected).text(); alert(foo[i]); }); It works but I get all the options in the select. Why is that? Is this the correct road to walk? Are there better ways to do this kind of check? Thank you very much!

  • IDbTransaction Rollback Timeout

    - by Ben
    I am dealing with an interesting situation where I perform many database updates in a single transaction. If these updates fail for any reason, the transaction is rolled-back. IDbTransaction transaction try { transaction = connection.BeginTransaction(); // do lots of updates (where at least one fails) transaction.Commit(); } catch { transaction.Rollback(); // results in a timeout exception } finally { connection.Dispose(); } I believe the above code is generally considered the standard template for performing database updates within a transaction. The issue I am facing is that whilst transaction.Rollback() is being issued to SQL Server, it is also timing out on the client. Is there anyway of distinguishing between a timeout to issue the rollback command and a timeout on that command executing to completion? Thanks in advance, Ben

    - by pmcgrath
    Has anyone managed to use this module with success, i'm running 32bit Windows 7, where i have opened an administrator shell using run as administrator, i have imported the WebAdministration module and then attempted to use the commands with some issues, have provided two examples here Websites I created a web site with the following command new-website -name testsite -port 80 -hostheader testsite -physicalpath c:\temp Then i attempted to get the sites details using the command get-website -name testsite but it always returns all sites, seems to ignore the -name parameter.

  • Strange behaviour with Microsoft.WindowsCE.Forms

    - by Mohammadreza
    I have a Windows Mobile application in which I want to check the device orientation. Therefore I wrote the following property in one of my forms: internal static Microsoft.WindowsCE.Forms.ScreenOrientation DeviceOriginalOrientation { get; private set; } The strange thing is that after that whenever I open a UserControl, the designer shows this warning even if that UserControl doesn't use the property: Could not load file or assembly 'Microsoft.WindowsCE.Forms, Version=3.5.0.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Commenting the above property will dismiss the warning and shows the user control again. The application is built successfully and runs without any problems in both cases. Does anybody know why this happens and how can I fix it?

  • sOperator as and generic classes

    - by abatishchev
    I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

  • Writing out BMP files with DataBuffer.TYPE_FLOAT or DataBuffer.TYPE_DOUBLE in java

    - by Basil Dsouza
    Hi Guys, I had a problem working with the image classes in java. I am creating a buffered image with DataBuffer.TYPE_DOUBLE. This all works fine in memory (I think). But the problem starts when I try to write it using ImageIO.write. Initially I was getting no exception at all and instead was only getting an empty output file for my troubles.. After a bit of poking around in the code, i found out that the bmp writer doesnt support writing type_double type of files. From: BMPImageWriterSpi.canEncodeImage: if (dataType < DataBuffer.TYPE_BYTE || dataType > DataBuffer.TYPE_INT) return false; So my question is, does anyone have a way of writing out those kind of images to disk? any documentation or tutorial, or link would be helpful. Thanks, Basil Dsouza

    Consider the following code: while(true) { someFunction(); Thread.sleep(1000); } What I want is that, someFunction() be called once every 10 seconds. But this is not the case. It is being called every second. I tried Thread.wait(1000), but even that doesnt help. I removed of the while part, just kept the body, and at the end wrote : Thread.start(); But it throwed an exception. Is there any other solution to this?

  • AnkhSVN, mysisgit and Pageant

    - by Chalkey
    I have recently installed msysgit on my machine (its running Windows 7) to use Git for some projects. A lot of my projects are under SVN, in which I use AnkhSVN in Visual Studio 2008 to commit etc. Since I have installed msysgit everytime I try to commit, update etc inside Visual Studio, the program C:\msysgit\bin\ssh.exe loads up, asks for my password, then Ankh throws an exception. I currently use Pageant to save my login credentials for SVN - I have TortoiseSVN installed, which is still working fine... Has anybody got any suggestions to get Anhk working again - without uninstalling msysgit? Thanks

  • synchronized block in JSP tag class

    - by Sudhakar
    Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())

  • Casting to generic type in Java doesn't raise ClassCastException?

    - by Kip
    I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

  • Workflow 4.0 code activities calling other activites (persist, delay etc)

    - by Lygpt
    I have a bunch of Workflow foundation 4.0 RC code activities that consume web services and talk to databases that I want to add some error handling in. I would really like to be able to attempt to call my web service / db, catch any faults such as a communication failure and then retry the same operation in 1 hours time (after I have logged the exception). Is there a way of doing something like this? protected override void Execute(CodeActivityContext context) { Persist(); // I would like to invoke the persist activity like this if (!AttemptServiceCall()) { // I would like to invoke a delay activity like this Delay(new TimeSpan(0, 30, 0)); // wait 30 mins before trying again Execute(context); // call this activity again } } private bool AttemptServiceCall() { bool serviceCallSuccessful = true; try { myService.InvokeSomeMethod(); } catch (CommunicationException ex) { myEventLogger.Log(ex); serviceCallSuccessful = false; } return serviceCallSuccessful; }
