  • C# Process.Start() on an executable on a remote system - security warning?

    - by BrettRobi
    I've created a Windows Service that accepts commands from remote machines via WCF. One of those commands is to run a specified executable (let's ignore the security implications of such functionality). In my Service I am using Process.Start() to run the executable. All works well if the executable is local to the machine, but if it is on a remote file share it is failing with no error (or more accurately just hanging). I suspect the problem is that it is triggering the standard Windows 'Unverified Publisher' warning that one would see if they double click an exe on a remote system. Is there any way I can bypass this from my service so that I can truly run any executable? As I said I understand the security implications of allowing it to run any executable, but this is really what I need. I would have thought this warning was only a user mode concept, but it really does seem to be getting in the way of my Service. Ideas?

  • Standalone GUI client for TFS 2010 Source Control

    - by Seth Reno
    I'm looking for a TFS 2010 GUI client that I can use outside of an IDE. I'm only looking to use the source control features in this case. I'm not talking about work items or build management. Ideally it would be a complete client that can be used on a machine where Visual Studio is not installed. Options I know about and why I'm not satisfied with them: TFS Power Tools - Windows Shell Extension Must have a working copy to use... see chicken or the egg Missing features: view history, branch / merge, revert SvnBridge TFS 2010 not yet supported Are there others that I don't know about?

  • Detach an entity from a JPA persistence context (JPA 2.0 / Hibernate / EJB 3 / J2EE 6)

    - by Julien
    Hi, I wrote a stateless EJB method allowing to get an entity in "read-only" mode. The way to do this is to get the entity with the EntityManager then detach it (using the JPA 2.0 EntityManager). My code is the following: @PersistenceContext private EntityManager entityManager; public T getEntity(int entityId, Class<T> specificClass, boolean readOnly) throws Exception{ try{ T entity = (T)entityManager.find(specificClass, entityId); if (readOnly){ entityManager.detach(entity); } return entity; }catch (Exception e){ logger.error("", e); throw e; } } Getting the entity works fine, but the call to the detach method returns the following error: GRAVE: javax.ejb.EJBException at ... Caused by: java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerImpl.detach(Ljava/lang/Object;)V at com.sun.enterprise.container.common.impl.EntityManagerWrapper.detach(EntityManagerWrapper.java:973) at com.mycomp.dal.MyEJB.getEntity(MyEJB.java:37) I can't get more information and don't understand what the problem is... Could somebody help ?

  • iPad: SplitView does not rotate

    - by raj.tiwari
    I have the following setup: A subclass of UISplitViewController that creates the master and detail view controllers in the constructor. Master and Detail view controllers that both override shouldAutorotateToInterfaceOrientation to return `YES'. Detail view controller implements the UISplitViewControllerDelegate protocol and deals with the popover. I am observing two weird issues that might be interrelated: When the split view comes up (in portrait mode - default on simulator), the Master view is visible. It should not be. When I rotate the simulator, the view does not "right" itself. My UISplitViewController subclass does not override shouldAutorotateToInterfaceOrientation. However, both master and details view controllers do and return YES. Any ideas what I might be doing wrong? Is this a simulator bug? Thanks. -Raj

  • WPF ShowDialog returns immediately

    - by dthrasher
    Sometimes when I call ShowDialog on an OpenFileDialog Window in WPF, the dialog closes immediately with a return value of false. I'm calling ShowDialog in response to a button click event. I can reproduce this problem using the sample code for OpenFileDialog on MSDN: // Configure open file dialog box Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog(); dlg.FileName = "Document"; // Default file name dlg.DefaultExt = ".txt"; // Default file extension dlg.Filter = "Text documents (.txt)|*.txt"; // Filter files by extension // Show open file dialog box Nullable<bool> result = dlg.ShowDialog(); // Process open file dialog box results if (result == true) { // Open document string filename = dlg.FileName; } The problem occurs intermittently when I run my solution in Debug mode from Visual Studio 2008 SP1. It's quite annoying. Is this a known issue? Are there workarounds?

  • Telerik RadGrid doesn't display on first Page_Load but does on postback

    - by Mark
    I have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler. My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time. How do I get it to display the grid the first time the page loads?

  • VSDBCMD returns "An unexpected failure occurred: Object reference not set to an instance of an objec

    - by Matt Wrock
    I have been succesfully using the command line database deployment tool VSDBCMD on my dev and test environments but the tool fails in our integration environmrnt. I am using the VS 2010 version of the tool. The servers have all of the prerequisites including: .net 4.0 sql server compact edition 3.5 sp1 (as well as the full edition of 2008) sql server 2008 server management objects sql server 2008 native client sql server system clr types msxml 6 all of the dependent DLLs included in: C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\desktop*.dll C:\Program Files\Microsoft SQL Server Compact Edition\v3.5*.dll C:\Program Files (x86)\Microsoft Visual Studio 10.0\VSTSDB\Deploy**. The only reference to this error that I have been able to find has to do with a bug in the VS 2008 edition when the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0 key is missing. In my case the 10.0 version of the key exists. Has anyone else encountered this?

  • Debugging unmanaged code while debugging managed code

    - by sc_ray
    Hi, The .NET 3.5 application I am working on consists of bunch of different solutions. Some of these solutions consist of managed code(C#) and others have unmanaged code(C++). Methods written in C# communicate with the ones written in C++. I am trying to trace the dependencies between these various functions and I thought setting breakpoints on the solution consisting my C++ functions. One of the C# solutions have the startup project. I run this solution in debug mode with the expectation that the breakpoints in my unmanaged code will be hit but nothing really happens. Can somebody guide me through the process of debugging mixed applications such as these using the Visual Studio IDE? Thanks

  • CruiseControl [.Net] vs TeamCity for continuous integration?

    - by zappan
    i would like to ask you which automated build environment you consider better, based on practical experience. i'm planning to do some .Net and some Java development, so i would like to have a tool that supports both these platforms. i've been reading around and found out about CruiseControl.NET, used on stackoverflow development, and TeamCity with its support for build agents on different OS-platforms and based on different programming languages. so, if you have some practical experience on both of those, which one you prefer and why. currently, i'm mostly interested in the ease of use and management of the tool, much less in the fact that CC is open source, and TC is a subject to licensing at some point when you have much projects to run (because, i need it for a small amount of projects). also, if there is some other tool that meets the above-mentioned and you believe it's worth a recommendation - feel free to include it in the discussion.

  • ExtJS RowEditor on Grid

    - by Ian Warner
    Hi When my users edits the Grid via RowEditor combo entries and checkboxes are annoying 1 Apple 2 Orange 3 Pear For instance with the combo above the user will select Orange then update - the Grid now instead of saying orange will display the number 2 - I would like it to show orange when a successful edit has been made. code for my combo editor : { allowBlank : false, displayField : 'team', editable : false, emptyText : 'Select Team', forceSelection : true, lazyRender : true, mode : 'remote', name : 'team', store : storeTeam, triggerAction : 'all', valueField : 'id', xtype : 'combo' } I think I read that you could send the complete row back to insert or I should listen to the update of the grid and then change the field but I need some guidance on what is best Cheers

  • Determine UIInterfaceOrientation on iPad

    - by JustinXXVII
    I don't need to specify the orientation in this case, I just need to detect it, but I'm having trouble. I have conditional code that should only work in portrait, and if the device is in landscape I need to do something else. Since the deviceOrientation is not necessarily the same as the interfaceOrientation, I can't come up with a way to test for portrait mode. Most tutorials I find on Google are ways to force landscape or do some sort of rotation. The only thing I want to do is just determine what the orientation is. Here is my code, which is not working: -(void)viewDidLoad { [super viewDidLoad]; //currentOrientation is declared as UIInterfaceOrientation currentOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation]; NSLog(@"%@",currentOrientation); // == NULL } I need to determine the value of the interfaceOrientation and program conditionally. Thanks for your help!

  • tcpdump on dd-wrt router

    - by Senica Gonzalez
    I'm trying to capture packets from two devices on my network. I have tcpdump installed on my dd-wrt router and working correctly. However, the only packets I capture are broadcast packets when using a tcpdump statement that states only those two devices ./tcpdump -w /tmp/capture.pcap dst 192.168.3.105 or src 192.168.3.105 or dst 192.168.3.136 or src 192.168.3.136 I'm capturing on intefface br0. Is that correct? Both devices are plugged in directly to the ports 1 and 2 with ip addresses 192.168.3.105 and 192.168.3.136 respectively. Do I need to set br0 in promiscuous mode? A little stuck. Thanks.

    Hi, I want to an autocomplete dropdown control in the ultrawebgrid cell in edit mode, so user can type the data and value is filled in automatically if exists, invalid data should not be permitted. is this possible? I don't want to use webcombo, it is too heavy and I don't need a multi-column dropdown. I want a simple dropdownlist, but the ability for the user to type just like Google suggest, but all the values cached on the client, no roundtrip to server on each key stroke. the control should be like the following one http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx thanks, RK

  • Change/check minimum iPhone OS for Universal apps?

    - by Moshe
    The dropdown in XCode shows a base SDK of 3.2, but my iPod Touch (2nd generation), running OS 3.1.3, will run the app just fine in debug mode. (Command + Return/Enter) What is the actual base SDK of my iPhone/iPod touch version of the app and how can I change this? Changing it by right clicking on the project name in the "Groups and Files" pane and changing "Base SDK" under the "Build", doesn't do much. Edit: While writing this question, I found that scrolling down in "Build" and changing "iPhone OS Deployment Target" seems to be what I'm looking for, I'm posting this anyway. Perhaps someone has more insight into this...

  • Zend_Form : Adding fields in sub-forms on user's click

    - by anu iyer
    I'm having a zend form - comprised of a number of zend - sub forms, where the user is creating a new question (its a content management system). In one of the subforms, the user can click on a button to add more textfields, like this: [----------] [----------] [click to add more] which should give [----------] [----------] [----------] [click to add more] I'm trying to set a flag in the sub form in question - or set a count on how many times the button has been clicked, to add that many total fields to the subform - but its simply not working. I tried using a static count variable - but the value doesnt get incremented at all. Any thoughts on how to do this in a Zend-subform within a zend form? I'll definitely update if I hit a solution. Thanks!

    - by Fábio Antunes
    Hello everybody. I'm doing a small web app, which uses CKeditor for user input, and CKfinder for file management (images/flash).

  • iPad SplitView changes main navigation bar color

    - by JustinXXVII
    Weird problem: After rotating my app to portrait, picking the toolbar item and exposing the uipopovercontroller, if I rotate back to landscape, the UINavigationController on the right side (objectAtIndex:0 of the SplitView) changes the color of the navigation bar. I am not sure why. I have it set in Interface Builder to be barStyle = UIBarStyleBlackOpaque; It turns silver after it returns to landscape mode. This only happens if I rotate it to portrait, create the popover, and select something in the navigation controller, which pushes another tableViewController. Even setting the properties in the viewDidLoad method does nothing. Anyone have an idea?

  • AutoCompleteExtender - authentication failure (forms authentication)

    - by Paddy
    I'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily. If I change my service definition to include a demand for the caller to be authenticated, like so: <OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _ Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?

  • VBA ActiveX controls grow in size over Remote Desktop Connection

    - by Alistair Knock
    We have an Excel workbook with a number of ActiveX controls, running in Excel 2003 on Windows XP. When connecting using Remote Desktop, the ActiveX controls change font, sometimes font size, and sometimes orientation (in the case of a spinner control). This happens on first connection and also as the workbook is used - some of the controls then enlarge in size, often overlapping other controls and part of the workbook. I read somewhere this may be caused by improper connection management (not closing them) leading to increasing memory usage; are there other reasons why the display is so different over Remote Desktop and are there workarounds? (the properties of each control usually remain the same, so force-resizing them doesn't always have an effect)

  • Rails Resque workers fail with PGError: server closed the connection unexpectedly

    - by gc
    I have site running rails application and resque workers running in production mode, on Ubuntu 9.10, Rails 2.3.4, ruby-ee 2010.01, PostgreSQL 8.4.2 Workers constantly raised errors: PGError: server closed the connection unexpectedly. My best guess is that master resque process establishes connection to db (e.g. authlogic does that when use User.acts_as_authentic), while loading rails app classes, and that connection becomes corrupted in fork()ed process (on exit?), so next forked children get kind of broken global ActiveRecord::Base.connection I could reproduce very similar behaviour with this sample code imitating fork/processing in resque worker. (AFAIK, users of libpq recommended to recreate connections in forked process anyway, otherwise it's not safe ) But, the odd thing is that when I use pgbouncer or pgpool-II instead of direct pgsql connection, such errors do not appear. So, the question is where and how should I dig to find out why it is broken for plain connection and is working with connection pools? Or reasonable workaround?
