  • Where does PGP keep its license file within OS X?

    - by romant
    I was using a trial from PGP. Now have a license supplied by the company I work for. Upon trying to overwrite/upgrade - PGP is reporting that its using the 'old', namely trial license. Which has long expired. How can I completely rid my machine of PGP - and thus be able to install a fresh copy? Where does this pesky license file reside? OS: 10.6.2 PGP: 10

  • OutOfMemoryException with Image.Clone - Only on Windows 2003

    - by Jeff Rapp
    So here's my issue. I have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this: Dim bte() As Byte = System.Convert.FromBase64String(imgStr) Dim ms As New IO.MemoryStream(bte) Dim bmp As New System.Drawing.Bitmap(ms) Dim monoImage As Drawing.Bitmap = New Drawing.Bitmap(1200, 1800, Drawing.Imaging.PixelFormat.Format1bppIndexed) Dim rect As New Drawing.Rectangle(0, 0, 1200, 1800) monoImage = bmp.Clone(rect, Drawing.Imaging.PixelFormat.Format1bppIndexed) And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line. Any ideas as to what's happening, or perhaps a better solution to converting the image to B&W?

  • dropdowllist selected item from javascript to servlet

    - by kawtousse
    Hi, I am writing to ask if anybody knows, is it possible to get the value from a JavaScript variable and use this value in a Java Servlet? I have read up on this but all i have found is getting the JavaScript value through a form submit. What I need is: I have a html select combo box. I need to extract the selected value from this and use this value to query a database. Is this possible. Thanks in advance.

  • How do I turn an array of bytes back into a file and open it automatically with C#?

    - by Ace Grace
    Hi, I am writing some code to add file attachments into an application I am building. I have add & Remove working but I don't know where to start to implement open. I have an array of bytes (from a table field) and I don't know how to make it automatically open e.g. If I have an array of bytes which is a PDF, how do I get my app to automatically open Acrobat or whatever the currently assigned application for the extension is using C#?

  • Does the VB6 IDE run on Windows 7 64-bit

    - by jasonk
    We're approaching a point of replacing several of our developer PCs and would like to move up to 64-Bit to maximize the hardware/life of the PCs but we also need to support several legacy VB6 applications. That said, does the VB6 IDE run on Windows 7 64-bit? Microsoft says it's not supported, but that doesn't necessarily mean it doesn't work. Does it work? Are there any pitfalls/workarounds needed to get it running?

  • Working with Hibernate Queries

    - by jschoen
    I am new to hibernate queries, and trying to get a grasp on how everything works. I am using Hibernate 3 with Netbeans 6.5. I have a basic project set up and have been playing around with how to do everything. I started with essentially a search query. Where the user can enter values into one or more fields. The table would be Person with the columns first_name, middle_name, last_name for the sake of the example. The first way I found was to have a method that took firstName, middleName, and lastName as parameters: Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction tx = session.beginTransaction(); String query = "from Person where (first_name = :firstName or :firstName is null) "+ "and (middle_name = :middleName or :middleName is null) " "and (last_name = :lastname or :lastName is null)"; Query q = session.createQuery(query); q.setString("firstName", firstName); q.setString("middleName", middleName); q.setString("lastName", lastName); List<Person> results = (List<Person>) q.list(); This did not sit well with me, since it seemed like I should not have to write that much, and well, that I was doing it wrong. So I kept digging and found another way: Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction tx = session.beginTransaction(); Criteria crit = session.createCriteria(Person.class); if (firstName != null) { crit.add(Expression.ge("firstName", firstName); } if (middleName != null) { crit.add(Expression.ge("middleName", middleName); } if (lastName != null) { crit.add(Expression.ge("lastName", lastName); } List<Person> results = (List<Person>) crit.list(); So what I am trying to figure out is which way is the preferred way for this type of query? Criteria or Query? Why? I am guessing that Criteria is the preferred way and you should only use Query when you need to write it by hand for performance type reasons. Am I close?

  • Javascript "Member not found" error in IE8

    - by Steven
    I'm trying to debug the following block of Javascript code to see what the issue is. I'm getting an error that says "Member not found" on the line constructor = function() { in the extend:function() method. I'm not very good with Javascript, and I didn't write this, so I'm kind of lost on what the issue is. The error only occurs in IE8, it works fine in IE7 and Firefox. var Class = { create: function() { return function() { if(this.destroy) Class.registerForDestruction(this); if(this.initialize) this.initialize.apply(this, arguments); } }, extend: function(baseClassName) { constructor = function() { var i; this[baseClassName] = {} for(i in window[baseClassName].prototype) { if(!this[i]) this[i] = window[baseClassName].prototype[i]; if(typeof window[baseClassName].prototype[i] == 'function') { this[baseClassName][i] = window[baseClassName].prototype[i].bind(this); } } if(window[baseClassName].getInheritedStuff) { window[baseClassName].getInheritedStuff.apply(this); } if(this.destroy) Class.registerForDestruction(this); if(this.initialize) this.initialize.apply(this, arguments); } constructor.getInheritedStuff = function() { this[baseClassName] = {} for(i in window[baseClassName].prototype) { if(!this[i]) this[i] = window[baseClassName].prototype[i]; if(typeof window[baseClassName].prototype[i] == 'function') { this[baseClassName][i] = window[baseClassName].prototype[i].bind(this); } } if(window[baseClassName].getInheritedStuff) { window[baseClassName].getInheritedStuff.apply(this); } } return constructor; }, objectsToDestroy : [], registerForDestruction: function(obj) { if(!Class.addedDestructionLoader) { Event.observe(window, 'unload', Class.destroyAllObjects); Class.addedDestructionLoader = true; } Class.objectsToDestroy.push(obj); }, destroyAllObjects: function() { var i,item; for(i=0;item=Class.objectsToDestroy[i];i++) { if(item.destroy) item.destroy(); } Class.objectsToDestroy = null; } }

  • Question about spring manning-in-action

    - by Gandalf StormCrow
    I saw people asking about best book for learning spring, and I came across manning.spring in action was recommended most of the time so I decided to give it a go. The thing is the author offers some pretty reasonable explanations, puzzle by puzzle it gets in your head, than you just need to code it and you're done, you get it(this is how I work don't know about the others). When it comes to the code its very disapointing, I went trought the Knight example like 2 or 3 times by now and I see its incorrect in the book, I mean its hard already for people eager to learn and why not a note somewhere in the book like pseudo-code or something. The knight example in the first chapter is missing two classes QuestFailedException and HolyGrail I mean other people must have noticed this, why is everyone recommending this book without saying at least it has some errors(like many others do), was anyone actually been able to compile and this first chapter example?

  • LEFT OUTER JOIN with a WHERE clause

    - by Wesley
    I have two tables. indRailType contains a list of the names paired with an ID value that I use in other tables to indicate the rail type. WO_BreakerRail contains a date column and a rail code colume that corresponds to the same code in indRailType and some other data. There's a row in WO_BreakerRail for any activity on each rail type, for every date. So I could have 3 rows dated for 3/19/2010, each row indicates a different rail code, and what happened. When I use the following LEFT OUTER JOIN, I get a table with all the types of rail, with nulls in the rows where nothing happened on the 19th. Now, this is only working because I only have one date represented in my WO_BreakerRail table right now, the 19th. When I add more rows with different dates, things will go haywire. This is my SQL statement, which right now gives me exactly the results I want: SELECT WO_BreakerRail.ID, indRailType.RailType, WO_BreakerRail.CreatedPieces, WO_BreakerRail.OutsideSource, WO_BreakerRail.Charged, WO_BreakerRail.Rejected, WO_BreakerRail.RejectedToCrop FROM indRailType LEFT OUTER JOIN WO_BreakerRail ON indRailType.RailCode = WO_BreakerRail.RailCode Now, when I add in a WHERE WO_BreakerRail.Date = @Date clause I lose all the rows in the JOIN which nothing happened. I don't want that. From reading up, it sounds like a FULL OUTER JOIN is what I want, but SQL Server Compact Edition doesn't support FULL OUTER JOINs. Is there a way around this, or am I looking for something else entirely?

  • One big call vs. multiple smaller TSQL calls

    - by BrokeMyLegBiking
    I have a ADO.NET/TSQL performance question. We have two options in our application: 1) One big database call with multiple result sets, then in code step through each result set and populate my objects. This results in one round trip to the database. 2) Multiple small database calls. There is much more code reuse with Option 2 which is an advantage of that option. But I would like to get some input on what the performance cost is. Are two small round trips twice as slow as one big round trip to the database, or is it just a small, say 10% performance loss? We are using C# 3.5 and Sql Server 2008 with stored procedures and ADO.NET.

  • List.Sort in C#: comparer being called with null object

    - by cbp
    I am getting strange behaviour using the built-in C# List.Sort function with a custom comparer. For some reason it sometimes calls the comparer class's Compare method with a null object as one of the parameters. But if I check the list with the debugger there are no null objects in the collection. My comparer class looks like this: public class DelegateToComparer<T> : IComparer<T> { private readonly Func<T,T,int> _comparer; public int Compare(T x, T y) { return _comparer(x, y); } public DelegateToComparer(Func<T, T, int> comparer) { _comparer = comparer; } } This allows a delegate to be passed to the List.Sort method, like this: mylist.Sort(new DelegateToComparer<MyClass>( (x, y) => { return x.SomeProp.CompareTo(y.SomeProp); }); So the above delegate will throw a null reference exception for the x parameter, even though no elements of mylist are null. UPDATE: Yes I am absolutely sure that it is parameter x throwing the null reference exception! UPDATE: Instead of using the framework's List.Sort method, I tried a custom sort method (i.e. new BubbleSort().Sort(mylist)) and the problem went away. As I suspected, the List.Sort method passes null to the comparer for some reason.

  • castle monorail unit test rendertext

    - by MikeWyatt
    I'm doing some maintenance on an older web application written in Monorail v1.0.3. I want to unit test an action that uses RenderText(). How do I extract the content in my test? Reading from controller.Response.OutputStream doesn't work, since the response stream is either not setup properly in PrepareController(), or is closed in RenderText(). Example Action public DeleteFoo( int id ) { var success= false; var foo = Service.Get<Foo>( id ); if( foo != null && CurrentUser.IsInRole( "CanDeleteFoo" ) ) { Service.Delete<Foo>( id ); success = true; } CancelView(); RenderText( "{ success: " + success + " }" ); } Example Test (using Moq) [Test] public void DeleteFoo() { var controller = new MyController (); PrepareController ( controller ); var foo = new Foo { Id = 123 }; var mockService = new Mock < Service > (); mockService.Setup ( s => s.Get<Foo> ( foo.Id ) ).Returns ( foo ); controller.Service = mockService.Object; controller.DeleteTicket ( ticket.Id ); mockService.Verify ( s => s.Delete<Foo> ( foo.Id ) ); Assert.AreEqual ( "{success:true}", GetResponse ( Response ) ); } // response.OutputStream.Seek throws an "System.ObjectDisposedException: Cannot access a closed Stream." exception private static string GetResponse( IResponse response ) { response.OutputStream.Seek ( 0, SeekOrigin.Begin ); var buffer = new byte[response.OutputStream.Length]; response.OutputStream.Read ( buffer, 0, buffer.Length ); return Encoding.ASCII.GetString ( buffer ); }

  • On a Hudson master node, what are the .tmp files created in the workspace-files folder?

    - by Patrick Johnmeyer
    Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

I have a list of words, let's say: photo, free, search, image, css3, css, tutorials, webdesign, tutorial, google, china, censorship, politics, internet and I have a list of contexts: Programming World news Technology Web Design I need to try and match words with the appropriate context/contexts if possible. Maybe discovering word relationships in some way. Any ideas? Help would be much appreciated!

  • Proggraming a VPN, Authontication stage - RFC not clear enough

    - by John
    I have a custom build of a unix OS. My task: Adding an IPSec to the OS. I am working on Phase I, done sending the first 2 packets. what I am trying to do now is making the Identefication Payload. I've been reading RFC 2409 (Apendix B) which discuss the keying materials (SKEYID, SKEYID_d, SKEYID_a, SKEYID_e and the IV making). Now, I use SHA1 for authontication and thus I use HMAC-SHA1 & my encryption algorithem is AES 256bit. The real problem is that the RFC is not clear enough of what should I do regarding the PRF. It says: "Use of negotiated PRFs may require the PRF output to be expanded due to the PRF feedback mechanism employed by this document." I use SHA1, does it mean I do not negotiate a PRF? In my opinion, AES is the only algorithm that needs expention (a fixed length of 256bit), so, do i need to expand only the SKEYID_e? If you happen to know a clearer, though relible, source then the RFC please post a link. Thanks in advance!
