  • How do I fix my "Stream closed" error in spring-ws?

    - by mcherm
    I have working code using the spring-ws library to respond to soap requests. I moved this code to a different project (I'm merging projects) and now it is failing. I would like to figure out the reason for the failure. The symptom I get is this: when the HTTP request arrives, spring begins handling the call. Then I get the following exception: org.springframework.ws.soap.saaj.SaajSoapEnvelopeException: Could not access envelope: java.io.IOException: Stream closed; nested exception is javax.xml.soap.SOAPException: java.io.IOException: Stream closed at org.springframework.ws.soap.saaj.SaajSoapMessage.getEnvelope(SaajSoapMessage.java:109) <<more lines that don't matter>> Caused by: java.io.IOException: Stream closed at java.io.PushbackInputStream.ensureOpen(PushbackInputStream.java:57) at java.io.PushbackInputStream.read(PushbackInputStream.java:116) at org.apache.xerces.impl.XMLEntityManager$RewindableInputStream.read(Unknown Source) at org.apache.xerces.impl.XMLEntityManager.setupCurrentEntity(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.determineDocVersion(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl.parse(Unknown Source) at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227) at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696) ... 30 more Examining it in a debugger, it appears that spring successfully handles HTTP headers, but then when it begins to process the contents of the SOAP message itself, it chokes when reading the very first character of the body. Some googling for the error message suggests that the problem is that a PushbackInputStream which is apparently used for reading from the socket is read twice or perhaps has close() called and then is read afterward. It is happening inside of spring-ws, not my code, and since it worked fine before I moved the code to a new project it must have something to do with versions of spring, or something it uses like axis or xerces. But I can't find any differences in versions of these! Has anyone encountered this error before? Or do you have any suggestions of approaches I could take in troubleshooting this?

  • DirectShow Filter I wrote dies after 10-24 seconds in Skype video call

    - by Robert Oschler
    I've written a DirectShow push filter for use with Skype using Delphi Pro 6 and the DSPACK DirectShow library. In preview mode, when you test a video input device in the Skype client Video Settings window, my filter works flawlessly. I can leave it up and running for many minutes without an error. However when I start a video call after 10 to 24 seconds, never longer, the video feed freezes. The call continues fine with the call duration counter clicking away the seconds, but the video feed is dead, stuck on whatever frame the freeze happened (although after a long while it turns black which I believe means Skype has given up on the filter). I tried attaching to the process from my debugger with a breakpoint literally set on every method call and none of them are hit once the freeze takes place. It's as if the thread that makes the DirectShow FillBuffer() call to my filter on behalf of Skype is dead or has been shutdown. I can't trace my filter in the debugger because during a Skype call I get weird int 1 and int 3 debugger hard interrupt calls when a Skype video call is in progress. This behavior happens even with my standard web cam input device selected and my DirectShow filter completely unregistered as a ActiveX server. I suspect it might be some "anti-debugging" code since it doesn't happen in video input preview mode. Either way, that is why I had to attach to the process after the fact to see if my FillBuffer() called was still being called and instead discovered that appears to be dead. Note, my plain vanilla USB web cam's DirectShow filter does not exhibit the freezing behavior and works fine for many minutes. There's something about my filter that Skype doesn't like. I've tried Sleep() statements of varying intervals, no Sleep statements, doing virtually nothing in the FillBuffer() call. Nothing helps. If anyone has any ideas on what might be the culprit here, I'd like to know. Thanks, Robert

  • What's the best way to develop a debugging window for an ajax ASP.Net MVC application

    - by KallDrexx
    While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

  • Word VBA - Find text between delimiters and convert to lower case

    - by jJack
    I would like to find text which is between the < and characters, and then turn any found text into "normal" case, where first letter of word is capitalized. Here is what I have thus far: Function findTextBetweenCarots() As String Dim strText As String With Selection .Find.Text = "<" ' what about <[^0-9]+> ? .Find.Forward = True .Find.Wrap = wdFindContinue End With Selection.Find.Execute ' Application.Selection. ' how do I get the text between the other ">"? findCarotSymb = Application.Selection.Text End Function Or, is there a better way of doing this? I also approached the problem using the VBScript Regex 5.5 library, which worked on simple documents, but not on certain documents with complex tables. For example, trying to just bold the text (for simplicity): Sub BoldUpperCaseWords() Dim regEx, Match, Matches Dim rngRange As Range Set regEx = New RegExp regEx.Pattern = "<[^0-9]+>" regEx.IgnoreCase = False regEx.Global = True Set Matches = regEx.Execute(ActiveDocument.Range.Text) For Each Match In Matches ActiveDocument.Range(Match.FirstIndex, Match.FirstIndex + Len(Match.Value)).Bold = True Next End Sub would not work in a document with tables. In fact, it would not even bold the correct text (the text between the <. This leads me to believe I have a broader issue here that I am missing. Here is what a sample doc looks like. Notice the wrong text is bold:

    We began to notice that with Java 7 (particularly with update 4), that all our users began to see this with our Webstart app: [14:42:58,422] AWT-EventQueue-0(DEBUG) java.lang.SecurityException: class "CLASSNAME" does not match trust level of other classes in the same package [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.CPCallbackHandler$ChildElement.checkResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath$JarLoader.checkResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath$JarLoader.getResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath.getResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader$1.run(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader$1.run(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.security.AccessController.doPrivileged(Native Method) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader.findClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.jnlp.JNLPClassLoader.findClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.lang.ClassLoader.loadClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.lang.ClassLoader.loadClass(Unknown Source)...More Where CLASSNAME = pretty much every class at random points from several jars in the app execution, breaking several behavior. If our users were to use Java 6, they have no problems! Just 7 (update 4). We sign ALL our jars, both the main application jar and it's library jars. i.e Users launching our webstart app see the blue shield instead of yellow or red. This is obviously an issue as users are more frequently now upgrading to Java 7. I have tried to force our app to use Java 6 on the user machine either by using a previous installation(works), or installing a new one....with the j2se version="1.6" tag around resources but this causes it's own problems that would probably be best to make into it's own thread (the auto-jre-installation part). Did Oracle break Webstart security with Java 7u4? How do I solve this securityexception issue?

  • pass objective c object and primitive type into a void *

    - by user674669
    I want to pass 2 variables: UIImage * img int i into another method that only takes a (void *) I tried making a C struct containing both img and i struct MyStruct { UIImage *img; int i; } but xcode gives me an error saying "ARC forbids Objective-C objects in structs or unions" The next thing I tried is to write an objective-c class MyStruct2 containing img and i, alloc-initing an instance of it and typecasting it as (__bridge void*) before passing it to the method. Seems little involved for my use case. Seems like there should be a better way. What's the simplest way to achieve this? Thank you. Edit based on comments: I have to use void * as it is required by the UIView API. I created a selector as mentioned by UIVIew API + (void)setAnimationDidStopSelector:(SEL)selector Please see documentation for setAnimationDidStopSelector at http://developer.apple.com/library/ios/#documentation/uikit/reference/UIView_Class/UIView/UIView.html . It says ... The selector should be of the form: - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context I want to pass both img and i into the (void *)context argument.

  • Node.js/ v8: How to make my own snapshot to accelerate startup

    - by Anand
    I have a node.js (v0.6.12) application that starts by evaluating a Javascript file, startup.js. It takes a long time to evaluate startup.js, and I'd like to 'bake it in' to a custom build of Node if possible. The v8 source directory distributed with Node, node/deps/v8/src, contains a SconScript that can almost be used to do this. On line 302, we have LIBRARY_FILES = ''' runtime.js v8natives.js array.js string.js uri.js math.js messages.js apinatives.js date.js regexp.js json.js liveedit-debugger.js mirror-debugger.js debug-debugger.js '''.split() Those javascript files are present in the same directory. Something in the build process apparently evaluates them, takes a snapshot of state, and saves it as a byte string in node/out/Release/obj/release/snapshot.cc (on Mac OS). Some customization of the startup snapshot is possible by altering the SconScript. For example, I can change the definition of the builtin Date.toString by altering date.js. I can even add new global variables by adding startup.js to the list of library files, with contents global.test = 1. However, I can't put just any javascript code in startup.js. If it contains Date.toString = 1;, an error results even though the code is valid at the node repl: Build failed: -> task failed (err #2): {task: libv8.a SConstruct -> libv8.a} make: *** [program] Error 1 And it obviously can't make use of code that depends on libraries Node adds to v8. global.underscore = require('underscore'); causes the same error. I'd ideally like a tool, customSnapshot, where customSnapshot startup.js evaluates startup.js with node and then dumps a snapshot to a file, snapshot.cc, which I can put into the node source directory. I can then build node and tell it not to rebuild the snapshot.

  • C#JSON serialization

    - by Bridget the Midget
    I'm trying out the HighStock library for creating stock charts. To fill the chart with data, their example specifies this source. The first parameter is unixtime in milliseconds and the second parameter is the stock closing price. I don't know if this is valid json, but I would argue that the following would be a more appropriate way of writing json. [{"Closing":63.15000,"Date":1262559600000},{"Closing":64.75000,"Date":1262646000000}, ... I guess that I have no other option than to adapt to HighStocks syntax. I could solve this by looping and add correct syntax to a string, but that seems rudimentary. Would it be more wise to serialize C# objects to create my json, and if that's the case - how can I reach the syntax specified in the example? Lets just say this is my c# object: public class Quote { public double Date { get; set; } public decimal Closing { get; set; } } Am I making it unnecessary complex? Should I just format a json string?

  • yet another question about migrating to Java

    - by aloneguid
    Hi, There are plenty similar questions, but maybe responses to this one will save a developer's life :) I want to migrate to Java. The reasons are very clear: all the .NET vacancies are client and windows oriented (Silverlight developer, ASP.NET developer, WPF developer etc.) and none of them are any interest to me. I worked with .NET since it's beginning as our company decided to invest in .NET having C++ stack and all the natual problems, so I was just blindly following and actually enjoyed it as the products were mostly server oriented with mixed C++/C# code. Today I have beforementioned problem - can't find an inspiring job. I'd rather kill myself than start working on a Silverlight or WPF project. Searching Java vacancies shows promising results, however they all require a huge java-related technology stack and experience. The question is is there any chance to find a job quickly and without dramatic salary drop (I know that Java guys are usually better paid, so there must be a kind of a credit) and if not, how must time and effort does it take to migrate (my .NET knowledge mostly includes server-oriented technologies like NHibernate, WCF, threading, sockets, ASP.NET web services, Enterprise Library, NInject etc etc etc, and (still) some C++ leftovers). Thanks!

  • Proper use of the IDisposable interface

    - by cwick
    I know from reading the MSDN documentation that the "primary" use of the IDisposable interface is to clean up unmanaged resources http://msdn.microsoft.com/en-us/library/system.idisposable.aspx. To me, "unmanaged" means things like database connections, sockets, window handles, etc. But, I've seen code where the Dispose method is implemented to free managed resources, which seems redundant to me, since the garbage collector should take care of that for you. For example: public class MyCollection : IDisposable { private List<String> _theList = new List<String>(); private Dictionary<String, Point> _theDict = new Dictionary<String, Point>(); // Die, you gravy sucking pig dog! public void Dispose() { _theList.clear(); _theDict.clear(); _theList = null; _theDict = null; } My question is, does this make the garbage collector free memory used by MyCollection any faster than it normally would? edit: So far people have posted some good examples of using IDisposable to clean up unmanaged resources such as database connections and bitmaps. But suppose that _theList in the above code contained a million strings, and you wanted to free that memory now, rather than waiting for the garbage collector. Would the above code accomplish that?

  • Linked list recursive reverse

    - by Phoenix
    I was looking at the code below from stanford library: void recursiveReverse(struct node** head_ref) { struct node* first; struct node* rest; /* empty list */ if (*head_ref == NULL) return; /* suppose first = {1, 2, 3}, rest = {2, 3} */ first = *head_ref; rest = first->next; /* List has only one node */ if (rest == NULL) return; /* put the first element on the end of the list */ recursiveReverse(&rest); first->next->next = first; /* tricky step -- see the diagram */ first->next = NULL; /* fix the head pointer */ *head_ref = rest; } What I don't understand is in the last recursive step for e.g if list is 1-2-3-4 Now for the last recursive step first will be 1 and rest will be 2. So if you set *head_ref = rest .. that makes the head of the list 2 ?? Can someone please explain how after reversing the head of the list becomes 4 ??

  • Why would some $_POST variables go missing for a form with PHP?

    - by Chad Johnson
    Sometimes, multiple times a day in fact, users of my web application are submitting a certain form which has about a dozen form fields, half of which are hidden fields, and half of the $_POST data is simply not present in the processing script. Note that the fields that are not present are at the very bottom of the form. I know this because this raises a fatal error, and an email is dispatched to me which includes the post data. And of course, neither I nor any of the developers on my team can reproduce the problem. Flash is involved in the process, as I'm using a library called Uploadify to display a progress meter. Here is the flow...does anyone have ANY ideas at all why some of the post data would be getting wiped out? User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. This happens on multiple browsers (Firefox 3.5, 3.6, Safari, Internet Explorer 7, 8) and multiple platforms (Mac OS 10.5, 10.6 and Windows XP, 7).

  • How to elegantly handle ReturnUrl when using UrlRewrite in ASP.NET 2.0 WebForms

    - by Brian Kim
    I have a folder with multiple .aspx pages that I want to restrict access to. I have added web.config to that folder with <deny users="?"/>. The problem is that ReturnUrl is auto-generated with physical path to the .aspx file while I'm using UrlRewrite. Is there a way to manipulate ReturnUrl without doing manual authentication check and redirection? Is there a way to set ReturnUrl from code-behind or from web.config? EDIT: The application is using ASP.NET 2.0 WebForms. I cannot use 3.5 routing. EDIT 2: It seems like 401 status code is never captured. It returns 302 for protected page and redirects to login page with ReturnUrl. It does not return 401 for protected page. Hmm... Interesting... Ref: http://msdn.microsoft.com/en-us/library/aa480476.aspx This makes things harder... I might have to write reverse rewrite mapping rules to regex match ReturnUrl and replace it if it doesn't return 401... If it does return 401 I can either set RawUrl to Response.RedirectLocation or replace ReturnUrl with RawUrl. Anyone else have any other ideas?

  • how to: dynamically load google ajax api into chrome extension content script

    - by Hoff
    Hi there, I'm trying to make use of google's ajax apis in a chorme extension's "content script". On a regular html page, I would just do this: <script src="http://www.google.com/jsapi"></script> <script> google.load("language", "1"); </script> But since I'm trying to load the tranlation library dynamically from js code, I've tried: script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.type = "text/javascript"; document.getElementsByTagName("head")[0].appendChild(script); google.load('language','1') but the last line throws the following error: Uncaught TypeError: Object # has no method 'load' Funny enough, when i enter the same "google.load('language','1')" in chrome's js console, it works as intended... I've also tried with jquery's .getScript() but the same problem persists... Does anybody have any clue what might be the problem and how it could be solved? Many thanks in advance! Martin

  • Blocking on DBCP connection pool (open and close connnection). Is database connection pooling in OpenEJB pluggable?

    - by topchef
    We use OpenEJB on Tomcat (used to run on JBoss, Weblogic, etc.). While running load tests we experience significant performance problems with handling JMS messages (queues). Problem was localized to blocking on database connection pool getting or releasing connection to the pool. Blocking prevented concurrent MDB instances (threads) from running hence performance suffered 10-fold and worse. The same code used to run on application servers (with their respective connection pool implementations) with no blocking at all. Example of thread blocked: Name: JMS Resource Adapter-worker-23 State: BLOCKED on org.apache.commons.pool.impl.GenericObjectPool@1ea6b4a owned by: JMS Resource Adapter-worker-19 Total blocked: 18,426 Total waited: 0 Stack trace: org.apache.commons.pool.impl.GenericObjectPool.returnObject(GenericObjectPool.java:916) org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:91) - locked org.apache.commons.dbcp.PoolableConnection@1bcba8 org.apache.commons.dbcp.managed.ManagedConnection.close(ManagedConnection.java:147) com.xxxxx.persistence.DbHelper.closeConnection(DbHelper.java:290) .... Couple of questions. I am almost certain that some transactional attributes and properties contribute to this blocking, but MDBs are defined as non-transactional (we use both annotations and ejb-jar.xml). Some EJBs do use container-managed transactions though (and we can observe blocking there as well). Are there any DBCP configurations that may fix blocking? Is DBCP connection pool implementation replaceable in OpenEJB? How easy (difficult) to replace it with another library? Just in case this is how we define data source in OpenEJB (openejb.xml): <Resource id="MyDataSource" type="DataSource"> JdbcDriver oracle.jdbc.driver.OracleDriver JdbcUrl ${oracle.jdbc} UserName ${oracle.user} Password ${oracle.password} JtaManaged true InitialSize 5 MaxActive 30 ValidationQuery SELECT 1 FROM DUAL TestOnBorrow true </Resource>

  • How to open child forms positioned within MDI parent in VB.NET?

    - by user961627
    How do we arrange child forms in a parent MDI window? I'm able to call and display a child form from a menu on the parent, but the child pops up outside the parent - I want it to actually be inside the parent. I've checked in C# and VB.Net solutions but they all say pretty much the same, i.e. try to access LayoutMDI, such as here: http://msdn.microsoft.com/en-us/library/x9fhk181.aspx The problem is, where do I access this? When I'm in the code of my MDI parent, Me.LayoutMdi is not recognized. In which part of the application do I put the Me.LayoutMDI code? Edit The Me.LayoutMDI code worked in the parent after all. I'd been trying for a while but don't know where I was going wrong. However, the child continues to pop up out of the parent. Here's an image of how that happens. The broader form in the back is the parent, and the one with the gridview and two buttons is the new child that popped up. I want it to pop up "Docked" within the parent.

  • Web Automation Tool

    - by Aaron
    I've realized I need a full-fledged browser automation tool for testing user interactions with our JavaScript widget library. I was using qunit, starting with unit testing and then I unwisely started incorporating more and more functional tests. That was a bad idea: trying to simulate a lot of user actions with JavaScript. The timing issues have gotten out of control and have made the suite too brittle. Now I spend more time fixing the tests, then I do developing. Is it possible to find a browser automation tool that works in: Windows XP: IE6,7,8, FF3 OSX: Safari, FF3 ? I've looked into SeleniumIDE and RC, but there seems to be some IE8 problems. I've also seen some things about Google's WebDriver, which confusingly seems to work with Selenium. Our organziation has licenses for IBM's Rational Functional Tester, but I don' think that will work on the MAC. The idea is to try to run tests on all the browsers our organization supports. Doable? Are my requirements unrealistic? Any recommendations as far as software to try? Thanks!

  • Linux: How to find all serial devices (ttyS, ttyUSB and others)?

    - by Thomas Tempelmann
    What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though?

  • PHP (A few questions) OO, refactoring, eclipse

    - by jax
    I am using PHP in eclipse. It works ok, I can connect to my remote site, there is colour coding of code elements and some code hints. I realise this may be too long to answer all questions, if you have a good answer for one part, answering just that is ok. Firstly General Coding I have found that it is easy to loose track of included files and their variables. For example if there was a database $cursor it is difficult to remember or even know that it was declared in the included file (this becomes much worse the more files you include). How are people dealing with this? How are people documenting their code - in particular the required GET and POST data? Secondly OO Development: Should I be going full OO in my development. Currently I have a functions library which I can include and have separated each "task" into a separate file. It is a bit nasty but it works. If I go OO how do I structure the directories in PHP, java uses packages - what about php? How should I name my files, should I use all lower case with _ for spaces "hello_world.php"? Should I name classes with Uppercase like Java "HelloWorld.php"? Is there a different naming convention for Classes and regular function files? Thirdly Refactoring I must say this is a real pain. If I change the name of a variable in one place I have to go through whole document and each file that included this file and change the name their too. Of course, errors everywhere is what results. How are people dealing with this problem? In Java if you change the name in one place it changes everywhere. Are there any plugins to improve php refactoring? I am using the official PHP version of Eclipse from their website. thanks

  • Unregistering COM dll with a C# Setup Project

    - by lb
    Hi All. I've been stuck on this one for a while. I'll try explain in the simplest terms and at the best of my knowledge. I will honour any help. I've got a C# project which uses a VB6 compiled ActiveX DLL that I'm constantly updating. I compile the setup project, send it to the client and they run the setup. When building the updated setup project, I would increase the 'Version' of the setup project so it wouldn't bother with 'Another version is already installed'. What started happening after a few updates I began to notice the DLL would not be updated to the new version in the installer. The client computer had the original DLL both installed and registered. First symptom: method not found exceptions from the client C# code. This is not a shared DLL and only this application needs it. I've noticed that when uninstalling the application (through the usual procedure) the DLL is also not removed from the application folder although I would set this file's property 'Permanent' to false. The registration entries in the registry are mantained also. I do update in VS6.0 the version of the DLL (usually increase the build number) before building it. Then in VS2008, I remove it from the References, and add it again from the 'Browse tab', without re-registering it on my dev machine and adding it from the COM tab. I've thought of these options. Custom step in Setup project to regsvr32.exe /u 'hardcoded path of my dll' at uninstall (ugly) Somehow find out how the 'Isolate' property can work for me without registering Find out how to execute setup project 'Conditions' that would actually check the version of the library and to update the file accordingly at every install) Any help would be incredibly welcome.

  • Linking error while using Qt static built libraries

    - by Kamran Amini
    I hope this is not a duplicate. Recently I'm developing a native C++ application using Qt 4.8.3 and VS2008. Since clients run the application on their naked machines, they need to install VC++ 2008 Redistribution package. So I decided to make it statically linked. I changed my project settings (C/C++ Code Generation Runtime Library) to /MTd. Also I compiled Qt again, this time using following commands for a static building; originally found on this blog Static Qt with static CRT (VS 2008) 1- replaced -MD with -MT in lines QMAKE_CFLAGS_RELEASE and QMAKE_CFLAGS_DEBUG in %QDIR%\mkspecs\win32-msvc2008\qmake.conf 2- nmake confclean 3- configure -static -platform win32-msvc2008 -no-webkit 4- nmake sub-src I compiled Qt successfully. But when I tried again to compile my application, it gave me some strange errors. 1>Linking... 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: bool __thiscall QBasicAtomicInt::deref(void)" (?deref@QBasicAtomicInt@@QAE_NXZ) already defined in QtCored4.lib(QtCored4.dll) 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: bool __thiscall QBasicAtomicInt::operator!=(int)const " (??9QBasicAtomicInt@@QBE_NH@Z) already defined in QtCored4.lib(QtCored4.dll) 1>qtmaind.lib(qtmain_win.obj) : error LNK2005: "public: __thiscall QString::~QString(void)" (??1QString@@QAE@XZ) already defined in QtCored4.lib(QtCored4.dll) I changed some lib files but with each change, situation got worse; for example I tried to use QtCored.lib instead of QtCored4.lib because it is newly created after compilation. I think I've missed something in building static Qt libs. Thanks.

  • Unit Testing Error - The unit test adapter failed to connect to the data source or to read the data

    - by michael.lukatchik
    I'm using VSTS 2K8 and I've set up a Unit Test Project. In it, I have a test class with a method that does a simple assertion. I'm using an Excel 2007 spreadsheet as my data source. My test method looks like this: [DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\MyTestData.xlsx;defaultdir=C:\\TestData;driverid=1046;maxbuffersize=2048;pagetimeout=5", "Sheet1", DataAccessMethod.Sequential)] [DeploymentItem("MyTestData.xlsx")] [TestMethod()] public void State_Value_Is_Set() { string expected = "MD"; string actual = TestContext.DataRow["State"] as string; Assert.AreEqual(expected, actual); } As indicated in the method decoration attributes, my Excel spreadsheet is on my local C:/ Drive. In it, the sheet where all of my data is located is named "Sheet1". I've copied the Excel spreadsheet into my project and I've set its Build Action = "Content" and I've set its Copy to Output Directory = "Copy if Newer". When trying to run this simple unit test, I receive the following error: The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library.

I've verified that the sheet name is spelled correctly (i.e. Sheet1) and I've verified that my data sources are set correctly. Web searches haven't turned up much at all. And I'm totally stumped. All help or input is appreciated!!!!
