• WPF abnormal CPU usage for animation

  - by 0xDEAD BEEF

  HI! I am developing WPF application and client reports extreamly high CPU usage (90%) (whereas i am unable to repeat that behavior). I have traced bootleneck down to these lines. It is simple glowing animation for small single led control (blinking led). What could be reason for this simple annimation taking up SO huge CPU resources? <Trigger Property="State"> <Trigger.Value> <local:BlinkingLedStatus>Blinking</local:BlinkingLedStatus> </Trigger.Value> <Trigger.EnterActions> <BeginStoryboard Name="beginStoryBoard"> <Storyboard> <DoubleAnimation Storyboard.TargetName="glow" Storyboard.TargetProperty="Opacity" AutoReverse="True" From="0.0" To="1.0" Duration="0:0:0.5" RepeatBehavior="Forever"/> </Storyboard> </BeginStoryboard> </Trigger.EnterActions> <Trigger.ExitActions> <StopStoryboard BeginStoryboardName="beginStoryBoard"/> </Trigger.ExitActions> </Trigger>

• SignalR - Handling disconnected users

  - by guilhermeGeek

  Hy, I'm using the signalR library on a project to handle an notification and chat modules. I've a table on an database to keep a track of online users. The HUB for chat is inheriting IDisconnect where i disconnect the user. After disconnecting the user, i warm the users about that event. At this point, i check if the disconnect user is the client. If it's, then i call an method on HUB to reconnect the user (just update the table). I do this because with the current implementation, once the user closes a tab on the browser it calls the Disconnect task but he could have another tab opened. I've not tested (with larger requests) this module yet, but on my development server it could take a few seconds between the IDisconnect event, and the request from the user to connect again. I'm concerned with my implementation to handle disconnected users from the chat but i can't see another way to improve this. If possible, could someone give me a advice on this, or this is the only solution that i've?

• Spaced repetition (SRS) for learning

  - by Fredrik Johansson

  A client has asked me to add a simple spaced repeition algorithm (SRS) for an onlinebased learning site. But before throwing my self into it, I'd like to discuss it with the community. Basically the site asks the user a bunch of questions (by automatically selecting say 10 out of 100 total questions from a database), and the user gives either a correct or incorrect answer. The users result are then stored in a database, for instance: userid questionid correctlyanswered dateanswered 1 123 0 (no) 2010-01-01 10:00 1 124 1 (yes) 2010-01-01 11:00 1 125 1 (yes) 2010-01-01 12:00 Now, to maximize a users ability to learn all answers, I should be able to apply an SRS algorithm so that a user, next time he takes the quiz, receives questions incorrectly answered more often; than questions answered correctly. Also, questions that are previously answered incorrectly, but recently often answered correctly should occur less often. Have anyone implemented something like this before? Any tips or suggestions? Theese are the best links I've found: http://en.wikipedia.org/wiki/Spaced_repetition http://www.mnemosyne-proj.org/principles.php http://www.supermemo.com/english/ol/sm2.htm

• What's the best way to read a UDT from a database with Java?

  - by Lukas Eder

  I thought I knew everything about UDTs and JDBC until someone on SO pointed out some details of the Javadoc of java.sql.SQLInput and java.sql.SQLData JavaDoc to me. The essence of that hint was (from SQLInput): An input stream that contains a stream of values representing an instance of an SQL structured type or an SQL distinct type. This interface, used only for custom mapping, is used by the driver behind the scenes, and a programmer never directly invokes SQLInput methods. This is quite the opposite of what I am used to do (which is also used and stable in productive systems, when used with the Oracle JDBC driver): Implement SQLData and provide this implementation in a custom mapping to ResultSet.getObject(int index, Map mapping) The JDBC driver will then call-back on my custom type using the SQLData.readSQL(SQLInput stream, String typeName) method. I implement this method and read each field from the SQLInput stream. In the end, getObject() will return a correctly initialised instance of my SQLData implementation holding all data from the UDT. To me, this seems like the perfect way to implement such a custom mapping. Good reasons for going this way: I can use the standard API, instead of using vendor-specific classes such as oracle.sql.STRUCT, etc. I can generate source code from my UDTs, with appropriate getters/setters and other properties My questions: What do you think about my approach, implementing SQLData? Is it viable, even if the Javadoc states otherwise? What other ways of reading UDT's in Java do you know of? E.g. what does Spring do? what does Hibernate do? What does JPA do? What do you do? Addendum: UDT support and integration with stored procedures is one of the major features of jOOQ. jOOQ aims at hiding the more complex "JDBC facts" from client code, without hiding the underlying database architecture. If you have similar questions like the above, jOOQ might provide an answer to you.

• Error in creating trigger using PHP script.. Please help!!!! Geeks

  - by Parth

  I've been successful in creating a simple trigger with a PHP script. The problem comes when I have to use "DELIMITER" in my trigger creating because I have nested if/then statements. For example, the following DOES work: $sql = 'CREATE TRIGGER `database`.`detail` BEFORE INSERT on `database`.`vibez_detail` FOR EACH ROW set @a=new.realtime_value'; $junk = mysqli_query($link, $sql); However, if I need to use "DELIMITER" I get errors galore. Here's what works if I go to the MySQL client at the server: DELIMITER $$; DROP TRIGGER `database`.`detail`$$ CREATE TRIGGER `database`.`detail` BEFORE INSERT on `database`.`vibez_detail` FOR EACH ROW BEGIN set new.data_rate = 69; insert into alarm_trips_parent values (null, new.data_rate, 6969, now()); set @tripped_time = now(); set @tripped:=true; end if; end if; END$$ DELIMITER ;$$ How can I construct the PHP code to get this to work? Seems the mysqli_query($link, $sql) chokes as soon as I put "DELIMITER" in the $sql variable. I get the following error when I attempt to do so: Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER //; CREATE TRIGGER `database`.`detail` BEFORE INS' at line 1 Even The concept for using mysqli_multi_query(); didn't worked for me.... :(

  I wrote a little code like this to start an ftp server embedded in my application. It's based on apache ftpserver I found that anonymous user could not login. Client keeps get 530. Do I have add a configure file for ftp? I can not find any API to create a User to add to UserManger. private void start_ftp() throws FtpException { FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); // set the port of the listener factory.setPort(DEF_FTP_PORT); // replace the default listener serverFactory.addListener("default", factory.createListener()); Ftplet fl = new MyFtplet(); Map<String, Ftplet> map_ftplest = new LinkedHashMap<String, Ftplet>(); map_ftplest.put("default", fl); serverFactory.setFtplets(map_ftplest); UserManagerFactory u_factory = new PropertiesUserManagerFactory(); UserManager u_manager = u_factory.createUserManager(); //u_manager.

• Can't start the portable version of NetBeans 6.9.1 IDE

  - by Coder

  I downloaded the portable version of netbeans netbeans-6.9.1-201007282301-ml.zip from the netbeans site and changed the config file in etc/netbeans.conf as indicated on the netbeans site. The file contents are below. # ${HOME} will be replaced by JVM user.home system property #netbeans_default_userdir="${HOME}/.netbeans/6.9" netbeans_default_userdir=".netbeans/6.9" # Options used by NetBeans launcher by default, can be overridden by explicit # command line switches: netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true" # Note that a default -Xmx is selected for you automatically. # You can find this value in var/log/messages.log file in your userdir. # The automatically selected value can be overridden by specifying -J-Xmx here # or on the command line. # If you specify the heap size (-Xmx) explicitely, you may also want to enable # Concurrent Mark & Sweep garbage collector. In such case add the following # options to the netbeans_default_options: # -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled # (see http://wiki.netbeans.org/wiki/view/FaqGCPauses) # Default location of JDK, can be overridden by using --jdkhome <dir>: #netbeans_jdkhome="/path/to/jdk" netbeans_jdkhome="C:\Program Files\Java\jdk1.6.0_24\" # Additional module clusters, using ${path.separator} (';' on Windows or ':' on Unix): #netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/cluster2" # If you have some problems with detect of proxy settings, you may want to enable # detect the proxy settings provided by JDK5 or higher. # In such case add -J-Djava.net.useSystemProxies=true to the netbeans_default_options. But it refuses to start when i try to run it. If i change the JDK path to something incorrect it complains that it can't find the jdk so i think the jdk path is correct. It also creates a .netbeans directory when i try to start it. I don't see any errors and it just doesn't do anything else observable. Does anybody know how to set up this version of netbeans? Thanks.

• Community License Agreement for Commercial (SaaS) software?

  - by indomitablehef

  I've got a commercial SaaS application, an online collaboration/lean project mgmt tool. I want to offer a "Community Edition", with specific limitations on how the software can be used, for free. For example free for groups using it to manage open source projects free to K-12 teachers to use in the classroom free for authors collaborating on Lean/Kanban/AgileSoftwareDevelopment books and research papers. free for community conference organizers, user group organizers, etc. The license would grant use of the software with limitations. The software itself can enforce limitations on the number of users/projects. I'm looking for a license agreement / EULA that I can use to specify what uses the software can be used for (see above). It would restrict the users from using it in different ways, such as for commercial use, managing consulting projects, client work, etc. I've been combing the web for good examples of such agreements, and so far coming up short. Any ideas? To be clear, this would not be an open source license of any kind. It would cover the use of commercial software, for specific "community" uses, as we define them.

• Azure SDK causes Node.js service bus call to run slow

  - by PazoozaTest Pazman

  I am using this piece of code to call the service bus queue from my node.js server running locally using web matrix, I have also upload to windows azure "web sites" and it still performs slowly. var sb1 = azure.createServiceBusService(config.serviceBusNamespace, config.serviceBusAccessKey); sbMessage = { "Entity": { "SerialNumbersToCreate": '0', "SerialNumberSize": config.usageRates[3], "BlobName": 'snvideos' + channel.ChannelTableName, "TableName": 'snvideos' + channel.ChannelTableName } }; sb1.getQueue('serialnumbers', function(error, queue){ if (error === null){ sb1.sendQueueMessage('serialnumbers', JSON.stringify(sbMessage), function(error) { if (!error) res.send(req.query.callback + '({data: ' + JSON.stringify({ success: true, video: newVideo }) + '});'); else res.send(req.query.callback + '({data: ' + JSON.stringify({ success: false }) + '});'); }); } else res.send(req.query.callback + '({data: ' + JSON.stringify({ success: false }) + '});'); }); It can be up to 5 seconds before the server responds back to the client with the return result. When I comment out the sb1.getQueue('serialnumbers', function(error, queue){ and just have it return without sending a queue message it performs in less than 1 second. Why is that? Is my approach to using the azure sdk service bus correct? Any help would be appreciated.

• IComparable not included when serializing in WCF

  - by djerry

  Hey guys, I have a list i'm filling at server side. It's a list of "User", which implements IComparable. Now when WCF is serializing the data, i guess it's not including the CompareTo method. This is my Object class : [DataContract] public class User : IComparable { private string e164, cn, h323; private int id; private DateTime lastActive; [DataMember] public DateTime LastActive { get { return lastActive; } set { laatstActief = value; } } [DataMember] public int Id { get { return id; } set { id = value; } } [DataMember] public string H323 { get { return h323; } set { h323 = value; } } [DataMember] public string Cn { get { return cn; } set { cn = value; } } [DataMember] public string E164 { get { return e164; } set { e164 = value; } } public User() { } public User(string e164, string cn, string h323, DateTime lastActive) { this.E164 = e164; this.Cn = cn; this.H323 = h323; this.LastActive= lastActive; } [DataMember] public string ToStringExtra { get { if (h323 != "/" && h323 != "") return h323 + " (" + e164 + ")"; return e164; } set { ;} } public override string ToString() { if (Cn.Equals("Trunk Line") || Cn.Equals("")) if (h323.Equals("")) return E164; else return h323; return Cn; } public int CompareTo(object obj) { User user = (User)obj; return user.LastActive.CompareTo(this.LastActive); } } Is it possible to get the CompareTo method to reach the client? Putting [DataMember] isn't the solution as i tried it ( i know...). Thanks in advance.

• Publishing artifacts with sources on archiva

  - by Palimondo

  At work I'm dipping my toes in managing project dependencies with maven. We use Apache Archiva (1.2.1) as a local repository and proxy. I'm adding artifact for open source project, that is not published on any public repository. I've learned that to publish the sources I should use the Classifier field on Upload artifact page. The sources are then listed alongside the jar and pom when I browse the repository. But when I update my maven dependencies I get only the jar and pom from the repository. I noticed that sources are also missing when the archiva proxies for me the downloads from other public repositories. I didn't find any configuration options in Archiva's admin pages to serve the sources... What am I missing? Update: I was missing the fact that artifact sources have to be downloaded manually. I.e. the maven client has to request them, which is controlled by command line option -DdownloadSources=true. Maven Integration for Eclipse has a preference setting to always download them as described in Resolving artifact sources. Archiva then serves the sources for local artifacts or proxies the request to remote repositories and caches the sources for future requests.

• Windows Screensaver Multi Monitor Problem

  - by Bryan

  I have a simple screensaver that I've written, which has been deployed to all of our company's client PCs. As most of our PCs have dual monitors, I took care to ensure that the screensaver ran on both displays. This works fine, however on some systems, where the primary screen has been swapped (to the left monitor), the screensaver only works on the left (primary) screen. The offending code is below. Can anyone see anything I've done wrong, or a better way of handling this? For info, the context of "this", is the screensaver form itself. // Make form full screen and on top of all other forms int minY = 0; int maxY = 0; int maxX = 0; int minX = 0; foreach (Screen screen in Screen.AllScreens) { // Find the bounds of all screens attached to the system if (screen.Bounds.Left < minX) minX = screen.Bounds.Left; if (screen.Bounds.Width > maxX) maxX = screen.Bounds.Width; if (screen.Bounds.Bottom < minY) minY = screen.Bounds.Bottom; if (screen.Bounds.Height > maxY) maxY = screen.Bounds.Height; } // Set the location and size of the form, so that it // fills the bounds of all screens attached to the system Location = new Point(minX, minY); Height = maxY - minY; Width = maxX - minX; Cursor.Hide(); TopMost = true;

• Best way to replace mass emails sent from Entourage with a proper mailing list solution?

  - by aaandre

  I am helping a Los Angeles choreographer to transition away from sending her announcements via Entourage. Here's the situation: She has multiple conact groups, and sends classes and performance announcements several times a month, to different groups. She manages the contact groups manually. The group size is between 1500 and 2500 people. Recently verizon blocked her outgoing port 25, presumably for spam activity. Again, her contacts are interested in the content. She is aware of mailchimp, constantcontact etc. but would like to be able to send the email via her email software and not have to create a newsletter for every single mailing. Also, she's very short on $$. So, what would be the best way to set up a system allowing her to send announcements from Entourage, with attached images, to her lists, without having Entourage send every single email? I am thinking of setting up a set of mailing lists, each corresponding to one of her groups. I have never set up a mailing list before and am wondering if it's possible to have a list accept emails from only one person (Admin) and distribute them to the group? Recipients should be able to unsubscribe easily, and by default reply to her but not the list. She should be the only one able to use the list for distribution, and should be able to send messages (with attachments) directly from her email client without modification. Is this possible? Where can I find step-by-step instructions? What are best practices to avoid her domain being blacklisted? What's the easiest way to convert her contact groups to mailing list subscribers? I am helping her for free, so the simpler the better :) Thank you! UPDATE: She has a standard linux hosting account allowing her to run php etc. And, ideally, the emails would come from her personally or at least from her domain name.

• unable to implement HTTP Tunneling correctly in order to enable Java rmi calls over internet(and und

  in my previous question :-How to Setup RMI Server under(NAT/ISP) Now,i m able to start my RMI server by Installing apache Tomcat 6.0 server. i have also installed servlet programs into apache Tomcat server in order to enable HTTP tunneling. my servlet codes:- (1) [SimplifiedServletHandler.java][2] (2) [ServletForwardCommand.java][3] these servlets resides inside :- C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\examples\WEB-INF\classes\ one more thing that i hv added to my CalcultorClient.java program:- try { RMISocketFactory. setSocketFactory(new sun.rmi.transport.proxy .RMIHttpToCGISocketFactory( )); }catch (IOException ignored) { System.out.println("Error :- ignored.getMessage()"); } But,when i try to make client connect with server(under ISP/NAT) i get the following Exception :- RemoteException java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: java.io.IOException: HTTP request failed i don't know the correct reason behind this Exception.. but,i think that i haven't installed or invoke my servlet programs properly on server side. so,can anybody tell me the correct reason behind this error/Exception????? and if u think that it is servlet problem then tell me the correct procedure to run my serlvet program inside tomcat server.

• How to catch HttpRequestValidationException in production

  - by bruno

  Hello all, I have this piece of code to handle the HttpRequestValidationException in my global.asax.cs file. protected void Application_Error(object sender, EventArgs e) { var context = HttpContext.Current; var exception = context.Server.GetLastError(); if (exception is HttpRequestValidationException) { Response.Clear(); Response.StatusCode = 200; Response.Write(@"<html><head></head><body>hello</body></html>"); Response.End(); return; } } If I debug my webapplication, it works perfect. But when i put it on our production-server, the server ignores it and generate the "a potentially dangerous request.form value was detected from the client" - error page. I don't know what happens exactly... If anybody knows what the problem is, or what i do wrong..? Also I don't want to set the validaterequest on false in the web.config. The server uses IIS7.5, And I'm using asp.net 3.5. Thanks, Bruno

• Test Views in ASP.NET MVC2 (ala RSpec)

  - by Dmitriy Nagirnyak

  Hi, I am really missing heavily the ability to test Views independently of controllers. The way RSpec does it. What I want to do is to perform assertions on the rendered view (where no controller is involved!). In order to do so I should provide required Model, ViewData and maybe some details from HttpContextBase (when will we get rid of HttpContext!). So far I have not found anything that allows doing it. Also it might heavily depend on the ViewEngine being used. List of things that views might contain are: Partial views (may be nested deeply). Master pages (or similar in other view engines). Html helpers generating links and other elements. Generally almost anything in a range of common sense :) . Also please note that I am not talking about client-side testing and thus Selenium is just not related to it at all. It is just plain .NET testing. So are there any options to actually do the testing of views? Thanks, Dmitriy.

• Unable to change the system zone setting on Windows Server 2008 R2.

  - by Ganesh

  Hi All, I have an MFC application that tries to change the system zone setting on the Windows Server 2008 R2. I am using the SetTimeZoneInformation() API which fails with the error code 1314 .i.e. “A required privilege is not held by the client.”.

I have administrator privileges and when I run the application it still fails to change the system zone setting. Thanks in Advance, Ganesh

• Request for the permission of type 'System.Web.AspNetHostingPermission' when compiling web site

  - by ahsteele

  I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines I would change the machine's .NET Security Configuration to trust the local intranet. I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

• What is the best software design to use in this scenario

  - by domdefelice

  I need to generate HTML snippets using jQuery. The creation of those snippets depends on some data. The data is stored server-side, in session (where PHP is used). At the moment I achieved this - retrieving the data from the server via AJAX in form of JSON - and building the snippets via specific javascript functions that read those data The problem is that the complexity of the data is getting bigger and hence the serialization into JSON is getting even more difficult since I can't do it automatically. I can't do it automatically because some information are sensible so I generate a "stripped" version to send to the client. I know it is difficult to understand without any code to read, but I am hoping this is a common scenario and would be glad for any tip, suggestion or even design-pattern you can give me. Should I store both a complete and a stripped data on the server and then use some library to automatically generate the JSON from the stripped data? But this also means I have to get the two data synchronized. Or maybe I could move the logic server-side, this way avoiding sending the data. But this means sending javascript code (since I rely on jQuery). Maybe not a good idea. Feel free to ask me more details if this is not clear. Thank you for any help

• Can't get data with spaces into the database from Ajax POST request

  - by J Jones

  I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?

• Can a large transaction log cause cpu hikes to occur

  - by Simon Rigby

  Hello all, I have a client with a very large database on Sql Server 2005. The total space allocated to the db is 15Gb with roughly 5Gb to the db and 10 Gb to the transaction log. Just recently a web application that is connecting to that db is timing out. I have traced the actions on the web page and examined the queries that execute whilst these web operation are performed. There is nothing untoward in the execution plan. The query itself used multiple joins but completes very quickly. However, the db server's CPU hikes to 100% for a few seconds. The issue occurs when several simultaneous users are working on the system (when I say multiple .. read about 5). Under this timeouts start to occur. I suppose my question is, can a large transaction log cause issues with CPU performance? There is about 12Gb of free space on the disk currently. The configuration is a little out of my hands but the db and log are both on the same physical disk. I appreciate that the log file is massive and needs attending to, but I'm just looking for a heads up as to whether this may cause CPU spikes (ie trying to find the correlation). The timeouts are a recent thing and this app has been responsive for a few years (ie its a recent manifestation). Many Thanks,

• HTTP POST prarameters order / REST urls

  - by pq

  Let's say that I'm uploading a large file via a POST HTTP request. Let's also say that I have another parameter (other than the file) that names the resource which the file is updating. The resource cannot be not part of the URL the way you can do it with REST (e.g. foo.com/bar/123). Let's say this is due to a combination of technical and political reasons. The server needs to ignore the file if the resource name is invalid or, say, the IP address and/or the logged in user are not authorized to update the resource. Looks like, if this POST came from an HTML form that contains the resource name first and file field second, for most (all?) browsers, this order is preserved in the POST request. But it would be naive to fully rely on that, no? In other words the order of HTTP parameters is insignificant and a client is free to construct the POST in any order. Isn't that true? Which means that, at least in theory, the server may end up storing the whole large file before it can deny the request. It seems to me that this is a clear case where RESTful urls have an advantage, since you don't have to look at the POST content to perform certain authorization/error checking on the request. Do you agree? What are your thoughts, experiences?

• Android: Determine when app is being finalized

  - by Matt

  Hi all, I posted a question yesterday about determining when an app is being finalized vs destroyed for screen orientation change. Thanks to the answers I received I was able to resolve my problem with the screen orientation change. However, I am still running into a roadblock. This app I am working on logs into a website with an HttpClient. As long as the app remains in memory the HttpClient will retain the cookies from logging in. However, once it is killed, it would need to log in again. My question: How can I determine when the app is being killed from memory so I can set a boolean to false telling the app it has been removed from memory so the next time it starts it will read this and determine is must log in again? Or is it possible to serialize an HttpClient and put that in the savedInstanceState bundle? May extract the cookies from the client and put those in the savedInstanceState bundle? Is there something I'm completely missing here maybe? Any help or a point in the right direction is greatly appreciated because this one has me stumped. Thank you!

• How to detect if an application has UI elements in it from C# in Windows 7?

  - by Santhosh

  I have a c# application in Windows 7 that runs in Session 0. This application is basically a framework for software patches installation that will install patches in the background (in session 0). So this app will download patches from the server and start installing them on the client machines. The way it installs the patches is by calling CreateProcess("Patch.exe"). Now mostly, Patch.exe will be a non-ui silent installation and henceforth, installing the patch from session 0 goes through successfully. However, sometimes this Patch.exe happens to have some UI elements in it such as prompting the user for some details (like installation location, etc..) and let us say that these UI elements cannot be avoided. So is it possible for my installation framework (that runs in Session 0 written in C#), to know that the process Patch.exe which was created by my framework has any UI elements in it? The reason I ask is, if I determine that the application has any UI elements in it, then I do not want to continue with the installation (a crude way of doing this would be to kill the installer process Patch.exe, but that is a different story and not of concern here).
