Launching Intent.ACTION_VIEW intent not working on saved image file

- by Savvas Dalkitsis

First of all let me say that this questions is slightly connected to another question by me. Actually it was created because of that. I have the following code to write a bitmap downloaded from the net to a file in the sd card: // Get image from url URL u = new URL(url); HttpGet httpRequest = new HttpGet(u.toURI()); HttpClient httpclient = new DefaultHttpClient(); HttpResponse response = (HttpResponse) httpclient.execute(httpRequest); HttpEntity entity = response.getEntity(); BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); InputStream instream = bufHttpEntity.getContent(); Bitmap bmImg = BitmapFactory.decodeStream(instream); instream.close(); // Write image to a file in sd card File posterFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Android/data/com.myapp/files/image.jpg"); posterFile.createNewFile(); BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(posterFile)); Bitmap mutable = Bitmap.createScaledBitmap(bmImg,bmImg.getWidth(),bmImg.getHeight(),true); mutable.compress(Bitmap.CompressFormat.JPEG, 100, out); out.flush(); out.close(); // Launch default viewer for the file Intent intent = new Intent(); intent.setAction(android.content.Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse(posterFile.getAbsolutePath()),"image/*"); ((Activity) getContext()).startActivity(intent); A few notes. I am creating the "mutable" bitmap after seeing someone using it and it seems to work better than without it. And i am using the parse method on the Uri class and not the fromFile because in my code i am calling these in different places and when i am creating the intent i have a string path instead of a file. Now for my problem. The file gets created. The intent launches a dialog asking me to select a viewer. I have 3 viewers installed. The Astro image viewer, the default media gallery (i have a milstone on 2.1 but on the milestone the 2.1 update did not include the 3d gallery so it's the old one) and the 3d gallery from the nexus one (i found the apk in the wild). Now when i launch the 3 viewers the following happen: Astro image viewer: The activity launches but i see nothing but a black screen. Media Gallery: i get an exception dialog shown "The application Media Gallery (process com.motorola.gallery) has stopped unexpectedly. Please try again" with a force close option. 3D gallery: Everything works as it should. When i try to simply open the file using the Astro file manager (browse to it and simply click) i get the same option dialog but this time things are different: Astro image viewer: Everything works as it should. Media Gallery: Everything works as it should. 3D gallery: The activity launches but i see nothing but a black screen. As you can see everything is a complete mess. I have no idea why this happens but it happens like this every single time. It's not a random bug. Am i missing something when i am creating the intent? Or when i am creating the image file? Any ideas?

LDAP query on linux against AD returns groups with no members

- by SethG

I am using LDAP+kerberos to authenticate against Active Directory on Windows 2003 R2. My krb5.conf and ldap.conf appear to be correct (according to pretty much every sample I found on the 'net). I can login to the host with both password and ssh keys. When I run getent passwd, all my ldap user accounts are listed with all the important attributes. When I run getent group, all the ldap groups and their gid's are listed, but no group members. If I run ldapsearch and filter on any group, the members are all listed with the "member" attribute. So the data is there for the taking, it's just not being parsed properly. It would appear that I simply am using an incorrect mapping in ldap.conf, but I can't see it. I've tried several variations and all give the same result. Here is my current ldap.conf: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy hard nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=User pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad Here's the kicker: this config works 100% fine on a different linux box with a different distro. It does not work on the distro I am planning on switching to. I have installed from source the versions of pam_ldap and nss_ldap on the new box to match the old box, which fixed another problem I was having with this setup. Other relevant info is the original AD box was Windows 2003. It's mirror died a horrible hardware death so I'm trying to add two more 2003-R2 servers to the mirror tree and ultimately drop the old 2003 box. The new R2 boxes appear to have joined the DC forest properly. What do I need to do to get groups working? I've exhausted all the resources I could find and need a different angle. Any input is appreciated. Status update, 7/31/09 I have managed to tweak my config file to get full info from the AD and performance is nice and snappy. I replaced the back-rev'd copies of pam_ldap and nss_ldap with the current ones for the distro I'm using, so it's back to a standard out-of-the-box install. Here's my current config: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy soft nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_connect_policy oneshot referrals no nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=CN=Person,CN=Schema,CN=Configuration,DC=w2k,DC=cis,DC=ksu,DC=edu pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad ssl off tls_checkpeer no sasl_secprops maxssf=0 The remaining problem now is when you run the groups command, not all subscribed groups are listed. Some are (one or two), but not all. Group memberships are still honored, such as file and printer access. getent group foo still shows that the user is a member of group foo. So it appears to be a presentation bug, and does not interfere with normal operation. It also appears that some (I have not determined exactly how many) group searches do not resolve correctly, even though the group is listed. eg, when you run "getent group bar", nothing is returned, but if you run "getent group|grep bar" or "getent group|grep <bar_gid>" you can see that it indeed listed and your group name and gid are correct. This still seems like an LDAP search or mapping error, but I can't figure out what it is. I'm a heckuva lot closer than earlier in the week, but I'd really like to get this last detail ironed out.

Replace JBoss error page with Axis2 fault XML response

- by Dario

I'm developing a webservice with Axis2 1.4.1 on JBoss 4.2.3/Tomcat 5.5.27 and Java 1.5.0 (15-b04). It works flawlessly but when an exception happens I get a JBoss error 500 HTML page instead of an Axis2 XML/SOAP fault. This behavoir is vexing, because it difficults to handle errors in the webservice client or in SoapUI while developing. Can I change this to get the SOAP fault? Maybe it's just an Axis2 or JBoss parameter, but I didn't find any clue about. EDIT: Here goes the new stacktrace: [ERROR] WSDoAllReceiver: security processing failed org.apache.axis2.AxisFault: WSDoAllReceiver: security processing failed at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:214) at org.apache.rampart.handler.WSDoAllReceiver.processMessage(WSDoAllReceiver.java:86) at org.apache.rampart.handler.WSDoAllHandler.invoke(WSDoAllHandler.java:72) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:163) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.ws.security.WSSecurityException: The security token could not be authenticated or authorized at org.apache.ws.security.processor.UsernameTokenProcessor.handleUsernameToken(UsernameTokenProcessor.java:155) at org.apache.ws.security.processor.UsernameTokenProcessor.handleToken(UsernameTokenProcessor.java:53) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:311) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:228) at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:211) ... 23 more [ERROR] Servlet.service() para servlet AxisServlet lanzó excepción java.lang.NullPointerException at org.apache.rampart.RampartMessageData.<init>(RampartMessageData.java:308) at org.apache.rampart.MessageBuilder.build(MessageBuilder.java:61) at org.apache.rampart.handler.RampartSender.invoke(RampartSender.java:64) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.sendFault(AxisEngine.java:520) at org.apache.axis2.transport.http.AxisServlet.handleFault(AxisServlet.java:416) at org.apache.axis2.transport.http.AxisServlet.processAxisFault(AxisServlet.java:379) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:167) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) EDIT 2: After giving the bounty I found that I was wrong about 1.2.9-SNAPSHOT version of Axiom. I built it again, made sure the jars where correctly copied to lib directory and it worked! Finally, it was an Axiom bug, as said in the links provided by Vineet. Thanks!

Why might login failures cause SQL 2005 to dump and ditch?

- by Byron Sommardahl

Our SQL 2005 server began timing out and finally stopped responding on Oct 26th. The application logs showed a ton of 17883 events leading up to a reboot. After the reboot everything was fine but we were still scratching our heads. Fast forward 6 days... it happened again. Then again 2 days later. The last night. Today it has happened three times to far. The timeline is fairly predictable when it happens: Trans log backups. Login failure for "user2". Minidump Another minidump for the scheduler Repeated 17883 events. Server fails little by little until it won't accept any requests. Reboot is all that gets us going again (a band-aid) Interesting, though, is that the server box itself doesn't seem to have any problems. CPU usage is normal. Network connectivity is fine. We can remote in and look at logs. Management studio does eventually bog down, though. Today, for the first time, we tried stopping services instead of a reboot. All services stopped on their own except for the SQL Server service. We finally did an "end task" on that one and were able to bring everything back up. It worked fine for about 30 minutes until we started seeing timeouts and 17883's again. This time, probably because we didn't reboot all the way, we saw a bunch of 844 events mixed in with the 17883's. Our entire tech team here is scratching heads... some ideas we're kicking around: MS Cumulative Update hit around the same time as when we first had a problem. Since then, we've rolled it back. Maybe it didn't rollback all the way. The situation looks and feels like an unhandled "stack overflow" (no relation) in that it starts small and compounds over time. Problem with this is that there isn't significant CPU usage. At any rate, we're not ruling SQL 2005 bug out at all. Maybe we added one too many import processes and have reached our limit on this box. (hard to believe). Looking at SQLDUMP0151.log at the time of one of the crashes. There are some "login failures" and then there are two stack dumps. 1st a normal stack dump, 2nd for a scheduler dump.

Can't get heroku work with rails 3.x postgresql

Netbeans platform projects - problems with wrapped jar files that have dependencies

- by I82Much

For starters, this question is not so much about programming in the NetBeans IDE as developing a NetBeans project (e.g. using the NetBeans Platform framework). I am attempting to use the BeanUtils library to introspect my domain models and provide the properties to display in a property sheet. Sample code: public class MyNode extends AbstractNode implements PropertyChangeListener { private static final PropertyUtilsBean bean = new PropertyUtilsBean(); // snip protected Sheet createSheet() { Sheet sheet = Sheet.createDefault(); Sheet.Set set = Sheet.createPropertiesSet(); APIObject obj = getLookup().lookup (APIObject.class); PropertyDescriptor[] descriptors = bean.getPropertyDescriptors(obj); for (PropertyDescriptor d : descriptors) { Method readMethod = d.getReadMethod(); Method writeMethod = d.getWriteMethod(); Class valueType = d.getClass(); Property p = new PropertySupport.Reflection(obj, valueType, readMethod, writeMethod); set.put(p); } sheet.put(set); return sheet; } I have created a wrapper module around commons-beanutils-1.8.3.jar, and added a dependency on the module in my module containing the above code. Everything compiles fine. When I attempt to run the program and open the property sheet view (i.e.. the above code actually gets run), I get the following error: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:259) Caused: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory starting from ModuleCL@64e48e45[org.apache.commons.beanutils] with possible defining loaders [ModuleCL@75da931b[org.netbeans.libs.commons_logging]] and declared parents [] at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:261) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:399) Caused: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.commons.beanutils.PropertyUtilsBean.<init>(PropertyUtilsBean.java:132) at org.myorg.myeditor.MyNode.<clinit>(MyNode.java:35) at org.myorg.myeditor.MyEditor.<init>(MyEditor.java:33) at org.myorg.myeditor.OpenEditorAction.actionPerformed(OpenEditorAction.java:13) at org.openide.awt.AlwaysEnabledAction$1.run(AlwaysEnabledAction.java:139) at org.netbeans.modules.openide.util.ActionsBridge.implPerformAction(ActionsBridge.java:83) at org.netbeans.modules.openide.util.ActionsBridge.doPerformAction(ActionsBridge.java:67) at org.openide.awt.AlwaysEnabledAction.actionPerformed(AlwaysEnabledAction.java:142) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2351) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.AbstractButton.doClick(AbstractButton.java:389) at com.apple.laf.ScreenMenuItem.actionPerformed(ScreenMenuItem.java:95) at java.awt.MenuItem.processActionEvent(MenuItem.java:627) at java.awt.MenuItem.processEvent(MenuItem.java:586) at java.awt.MenuComponent.dispatchEventImpl(MenuComponent.java:317) at java.awt.MenuComponent.dispatchEvent(MenuComponent.java:305) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:638) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:296) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:196) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:188) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) I understand that beanutils is using the commons-logging component. I have tried adding the commons-logging component in two different ways (creating a wrapper library around the commons-logging library, and putting a dependency on the Commons Logging Integration library). Neither solves the problem. I noticed that the same problem occurs with other wrapped libraries; if they themselves have external dependencies, the ClassNotFoundExceptions propagate like mad, even if I've wrapped the jars of the libraries they require and added them as dependencies to the original wrapped library module. Pictorially: I'm at my wits end here. I noticed similar problems while googling: Is there a known bug on NB Module dependency Same issue I'm facing but when wrapping a different jar NetBeans stance on this - none of the 3 apply to me. None conclusively help me. Thank you, Nick

I'm having problems getting a Silverlight DataGrid to stretch to accommodate all the items in it's dataSource. I've got a Grid that contains two DataGrids.

How to get httrack to work with SSL on mac os x? (libssl.so not found)

- by cwd

I'm trying to use httrack website copier but the program is running and reporting "no-ssl" (ie: it does not have the capability to copy secure sites). From looking over this thread, it seems that the problem is either when I make & configure the program, or when I run the program, it is not finding the lib-ssl / open-ssl that I have installed. I think it is looking for /var/root/lib/libssl.so.1.0 The user on that forum states that he created a symlink which allowed httrack to find the ssl library in the non-default location. Perhaps that's what I need to do - but where do I create the link from and to? I'm not seeing that I have any libssl.so files installed on my system. Do I need the development package? If so, how do I install that? I used macports to install the current version of openssl that I have. I'm running OS X 10.6. Reserch I have run this command to try and debug: dtruss httrack 2&1 | grep ssl and that outputs this: stat64("libssl.so.1.0\0", 0x7FFF5FBFEE30, 0x7FFF5FBFF470) = -1 Err#2

Python bindings for a vala library

- by celil

I am trying to create python bindings to a vala library using the following IBM tutorial as a reference. My initial directory has the following two files: test.vala using GLib; namespace Test { public class Test : Object { public int sum(int x, int y) { return x + y; } } } test.override %% headers #include <Python.h> #include "pygobject.h" #include "test.h" %% modulename test %% import gobject.GObject as PyGObject_Type %% ignore-glob *_get_type %% and try to build the python module source test_wrap.c using the following code build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c However, the last command fails with an error $ ./build.sh Traceback (most recent call last): File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1720, in <module> sys.exit(main(sys.argv)) File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1672, in main o = override.Overrides(arg) File "/usr/share/pygobject/2.0/codegen/override.py", line 52, in __init__ self.handle_file(filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 84, in handle_file self.__parse_override(buf, startline, filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 96, in __parse_override command = words[0] IndexError: list index out of range Is this a bug in pygobject, or is something wrong with my setup? What is the best way to call code written in vala from python? EDIT: Removing the extra line fixed the current problem, but now as I proceed to build the python module, I am facing another problem. Adding the following C file to the existing two in the directory: test_module.c #include <Python.h> void test_register_classes (PyObject *d); extern PyMethodDef test_functions[]; DL_EXPORT(void) inittest(void) { PyObject *m, *d; init_pygobject(); m = Py_InitModule("test", test_functions); d = PyModule_GetDict(m); test_register_classes(d); if (PyErr_Occurred ()) { Py_FatalError ("can't initialise module test"); } } and building with the following script build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c CFLAGS="`pkg-config --cflags pygobject-2.0` -I/usr/include/python2.6/ -I."

Xcode/iPhone Development 6 months in - Annoyances

- by clearbrian

Hi I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to. Is there any way to prevent multiple windows opening all the time in XCode? a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor? b) Anyway to get debugger to appear in main editor. I have a big screen iMac and it's still window hell on Macs. When you come from Alt-Tab the Mac is a nightmare. 2) Anyway to get a toolbar item on the main editor to: a) Open Console (I know CMD-thingy-R) b) Open Break points (you have to open Debugger first then breakpoints) I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far. I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode). Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help. Can you automate Xcode like you can with Windows/ActiveX/VBA 3) Limit lookups using CMD + double click. If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView) Anyway to get it to limit to the current class or at least order so current class is first. 4) Find doesn't seem to loop backwards if result all above cursor position I'm in a class and I hit CMD + F for find. Find box appears. I enter some text hit return. It says I have x matches but only back arrow is highlight in Find But when I hit < it does nothing. I need to scroll to the top and redo the search. If the text is both forwards and backwards then both < are highlighted and it works. is this a bug or a 'feature' Missing Eclipse features I have been looking at the User Script menu but was wondering how powerful they are? 5) any scripts around to generate source from members such as description: @property @synthesize if I add a new member, run a script will generate @property/@syntesize and release in dealloc 7) any good sites for scripts? SCM Im having problems with SCM and Folders on HD under project Classes directory. You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON I create a Group for the Library in Xcode under Classes group. Classes JSON I drag the files from the folder into xcode into the JSON Group. I add them to the SCM and icon changes from ? to A but if I try and commit them it say folder /JSON is not under SCM. Can you drag a folder into Xcode so that it AND its files get included in SCM? Anyway to stop Xcode Help from being on top all the time. I keep feeling like punching it and telling it to get out of the way! :) I dont mind it open just not in the way once I've finished. Yes I know I can Ctrl-W Sites: the main site I use to learn Obj-C are : stackoverflow.com Google code Search - tonnes of full apps on here http://www.iphonedevsdk.com/forum/iphone-sdk-development/ Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) ) Safari - 100s of IT book though prob too many to keep up :) any others? Any site that gives simple examples for Obj-C/ UIKit The docs just show the methods but actual examples (Google code search has helped a lot here)

Java 7 update 6 installation fails on Windows 7 when Chrome is default browser

- by ali1234

I am configuring a brand new Lenovo U410 system with Windows 7 Home Premium for a user. I received the system direct from the shop. As part of the configuration I installed Java using the online installer. This worked correctly. Later, due to a mistake I made, I needed to restore the system to factory default. The factory default FORMATS C:\ and puts back (supposedly) the exact factory configuration. However, after doing this, I was no longer able to install Java successfully using the same method I used before. Now, whenever I attempt to use the online Java installer, the following happens. First of all, a window always appears "Welcome to Java", "Downloading Java Installer...". After short time this window disappears and then one of three things happens: The very first time I do this after doing a factory reset, I get a Windows error report, which contains this information: Application Name: JavaSetup7u5.exe Application Version: 7.0.50.6 Application Timestamp: 4feacd84 Fault Module Name: JavaIC.dll Fault Module Version: 9.9.9.9 Fault Module Timestamp: 4f2343d6 Exception Offset: 000052cb Exception Code: c0000417 Exception Data: 00000000 OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 1033 Additional Information 1: 773c Additional Information 2: 773cd78cf06816f8246f359fa270f3bb Additional Information 3: f51a Additional Information 4: f51aaea7d22f36fa9e3a626b5a5cd1c3 2. Subsequent runs produce either this error message: "Error: Java(TM) installer - Downloaded file C:\Users\\AppData\Local\Temp\fx-runtime.exe is corrupt." or Nothing happens at all. I Believe this is a red herring. Running the installer again causes a different error because the files were downloaded and the installer crashed before it could clean up. This isn't the actual problem, as when this happens the installer deletes the downloaded files, and then when you run it for the third time, it downloads everything again and does the javaic.dll crash. I suspect the downloader is appending to the existing files or something, causing the corruption. I have tried all of the above as Administrator and as a normal user. I have tried reseting the system to factory defaults several times. I have tried downloading with Chrome and Internet Explorer 9. I have tried uninstalling all anti-virus software and disabling the windows firewall entirely. The only thing which makes a difference is running the installer in Windows XP compatibility mode, which allows the installation to complete. I know I can workaround this error by using the offline installer so please don't post that as an answer. I am looking for an explanation of the root cause. Additionally, if I use the offline installer, the updater does not work. The updater also does not work if I install in XP mode. The updater fails because it works by just downloading the newest online setup and running it. Also remember that the installers are digitally signed. The signitures verify correctly so there is no way in hell that this is caused by corrupted downloads. Some theories I have: The Java setup files on java.com actually changed in between the first successful install and my later attempts. Seems unlikely as none of the version numbers have changed. However, I have seen a couple of reports of this error which showed up in the past 24 hours. This looks like the most likely explanation right now: http://www.oracle.com/us/corporate/press/1735645 - Oracle released 7 update 6 two days ago. Careful inspection of the installers reveal that they are in fact attempting to download .6, not .5 as the download page claims. Not actually correct. Only the update tool tries to install 7u6. The online installer still tries 7u5. However, 7u6 being released two days ago is too much of a coincidence to ignore. Update: The 7u6 online installer is available from Oracle technetwork. It crashes in exactly the same way. The factory reset software uses GMT-8 and I am on GMT-1. As a result, after factory reset, any software which cares to check would think that the system was restored 7 hours in the future, due to Window's awful policy of storing local time in the system clock. This could be confusing a certificate check or similar. Update: I discovered that this does cause Windows Update to fail. The workaround, setting the clock back before starting factory reset, does not enable Java to install correctly. The factory reset image isn't really the same as what is installed in the main partition when you buy the system. Naughty Lenovo. The installer appears to crash while installing or displaying something to do with the Ask.com toolbar. That seems to be what javaic.dll does. Microsoft Tuesday was the 14th. Some update in that could be causing this. However, I'm factory reseting the machine every time, so unless the patches get slipstreamed into the recovery image, or there is some mechanism by which they get silently installed even if updates are disabled, then I don't see how this can be the cause. Major breakthrough: The default browser on Lenovo systems is Google Chrome. I noticed that the JavaIC.dll "sponsor check" actually does a check on your default browser in order to decide which sponsor ad to display. Normally that would get you the Ask toolbar on IE9. But that toolbar doesn't work on Chrome, and so the installer tries to display a different ad. The different ad is what causes the crash. Changing the default browser to IE9 allows the installer to run correctly. So this looks like a genuine bug in the sponsor ad code in the installer, caused by a combination of Google Chrome default browser and not being in the US. (Installer also checks your location using IP geolocation service and displays different ads based on that.)

IE attachEvent on object tag causes memory corruption

- by larswa

I've an ActiveX Control within an embedded IE8 HTML page that has the following event MessageReceived([in] BSTR srcWindowId, [in] BSTR json). On Windows the event is registered with OCX.attachEvent("MessageReceived", onMessageReceivedFunc). Following code fires the event in the HTML page. HRESULT Fire_MessageReceived(BSTR id, BSTR json) { CComVariant varResult; T* pT = static_cast<T*>(this); int nConnectionIndex; CComVariant* pvars = new CComVariant[2]; int nConnections = m_vec.GetSize(); for (nConnectionIndex = 0; nConnectionIndex < nConnections; nConnectionIndex++) { pT->Lock(); CComPtr<IUnknown> sp = m_vec.GetAt(nConnectionIndex); pT->Unlock(); IDispatch* pDispatch = reinterpret_cast<IDispatch*>(sp.p); if (pDispatch != NULL) { VariantClear(&varResult); pvars[1] = id; pvars[0] = json; DISPPARAMS disp = { pvars, NULL, 2, 0 }; pDispatch->Invoke(0x1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, &disp, &varResult, NULL, NULL); } } delete[] pvars; // -> Memory Corruption here! return varResult.scode; } After I enabled gflags.exe with application verifier, the following strange behaviour occur: After Invoke() that is executing the JavaScript callback, the BSTR from pvars[1] is copied to pvars[0] for some unknown reason!? The delete[] of pvars causes a double free of the same string then which ends in a heap corruption. Does anybody has an idea whats going on here? Is this a IE bug or is there a trick within the OCX Implementation that I'm missing? If I use the tag like: <script for="OCX" event="MessageReceived(id, json)" language="JavaScript" type="text/javascript"> window.onMessageReceivedFunc(windowId, json); </script> ... the strange copy operation does not occur. The following code also seem to be ok due to the fact that the caller of Fire_MessageReceived() is responsible for freeing the BSTRs. HRESULT Fire_MessageReceived(BSTR srcWindowId, BSTR json) { CComVariant varResult; T* pT = static_cast<T*>(this); int nConnectionIndex; VARIANT pvars[2]; int nConnections = m_vec.GetSize(); for (nConnectionIndex = 0; nConnectionIndex < nConnections; nConnectionIndex++) { pT->Lock(); CComPtr<IUnknown> sp = m_vec.GetAt(nConnectionIndex); pT->Unlock(); IDispatch* pDispatch = reinterpret_cast<IDispatch*>(sp.p); if (pDispatch != NULL) { VariantClear(&varResult); pvars[1].vt = VT_BSTR; pvars[1].bstrVal = srcWindowId; pvars[0].vt = VT_BSTR; pvars[0].bstrVal = json; DISPPARAMS disp = { pvars, NULL, 2, 0 }; pDispatch->Invoke(0x1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, &disp, &varResult, NULL, NULL); } } delete[] pvars; return varResult.scode; } Thanks!

Event receiver on Content Type not triggered on WikiPageLibrary

- by Ciprian Grosu

Hello all, I created a new content type for a wiki page library. I added this content type to library by code (the interface did not allow this). Next, I added an event receiver to this content type (on ItemAdded and ItemAdding). My problem is that no event is trrigered. If I add this events directly to the wiki page library all works fine. Is there a limitation/bug/trick ? I looked at the content type attached to the library with SharePoint Manager and in his schema the part for event receiver is missing...I know that there should be something like: <XmlDocuments> <XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/events"> <spe:Receivers xmlns:spe="http://schemas.microsoft.com/sharepoint/events"> <Receiver> <Name> </Name> <Type>1</Type> <SequenceNumber>10000</SequenceNumber> <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly> <Class>RssFeedWP.ItemEventReceiver</Class> <Data> </Data> <Filter> </Filter> </Receiver> <Receiver> <Name> </Name> <Type>10001</Type> <SequenceNumber>10000</SequenceNumber> <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly> <Class>RssFeedWP.ItemEventReceiver</Class> <Data> </Data> <Filter> </Filter> </Receiver> </spe:Receivers> </XmlDocument> If I look with SPM to the content type added to site I see this part into schema. Here is my code: public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb web = (SPWeb)properties.Feature.Parent) { // create RssWiki content type SPContentType rssFeedContentType = new SPContentType(web.AvailableContentTypes["Wiki Page"], web.ContentTypes, "RssFeed Wiki Page"); // add rssfeed url field to the new content type AddFieldToContentType(web, rssFeedContentType, "RssFeed Url", SPFieldType.Note); // add use xslt check box field to the new content type AddFieldToContentType(web, rssFeedContentType, "Use Xslt", SPFieldType.Boolean); // add xslt url field to the new content type AddFieldToContentType(web, rssFeedContentType, "Xslt Url", SPFieldType.Note); web.ContentTypes.Add(rssFeedContentType); rssFeedContentType.Update(); web.Update(); AddContentTypeToList(web, rssFeedContentType); AddEventReceiversToCT(rssFeedContentType); //AddEventReceiverToList(web); } } private void AddFieldToContentType(SPWeb web, SPContentType ct, string fieldName, SPFieldType fieldType) { SPField rssUrlField = null; try { rssUrlField = web.Fields.GetField(fieldName); } catch (Exception ex) { if (rssUrlField == null) { web.Fields.Add(fieldName, fieldType, false); } } SPFieldLink rssUrlFieldLink = new SPFieldLink(web.Fields[fieldName]); ct.FieldLinks.Add(rssUrlFieldLink); } private static void AddContentTypeToList(SPWeb web, SPContentType ct) { SPList wikiList = web.Lists[listName]; wikiList.ContentTypesEnabled = true; wikiList.ContentTypes.Add(ct); wikiList.Update(); } private static void AddEventReceiversToCT(SPContentType ct) { //add event receivers string assemblyName = System.Reflection.Assembly.GetExecutingAssembly().FullName; string ctReceiverName = "RssFeedWP.ItemEventReceiver"; ct.EventReceivers.Add(SPEventReceiverType.ItemAdding, assemblyName, ctReceiverName); ct.EventReceivers.Add(SPEventReceiverType.ItemAdded, assemblyName, ctReceiverName); ct.Update(); } Thx !

Inherited varibles are not reading correctly when using bitwise comparisons

- by Shawn B

Hey, I have a few classes set up for a game, with XMapObject as the base, and XEntity, XEnviron, and XItem inheriting it. MapObjects have a number of flags, one of them being MAPOBJECT_SOLID. My problem is, that XEntity is the only class that correctly detects MAPOBJECT_SOLID. Both Items are Environs are always considered solid by the game, regardless of the flag's state. What is important, is that Environs and Item should almost never be solid. Here are the relevent code samples: XMapObject: class XMapObject : public XObject { public: Uint8 MapObjectType,Location[2],MapObjectFlags; XMapObject *NextMapObject,*PrevMapObject; XMapObject(); void CreateMapObject(Uint8 MapObjectType); void SpawnMapObject(Uint8 MapObjectLocation[2]); void RemoveMapObject(); void DeleteMapObject(); void MapObjectSetLocation(Uint8 Y,Uint8 X); void MapObjectMapLink(); void MapObjectMapUnlink(); }; XEntity: class XEntity : public XMapObject { public: Uint8 Health,EntityFlags; float Speed,Time; XEntity *NextEntity,*PrevEntity; XItem *IventoryList; XEntity(); void CreateEntity(Uint8 EntityType,Uint8 EntityLocation[2]); void DeleteEntity(); void EntityLink(); void EntityUnlink(); Uint8 MoveEntity(Uint8 YOffset,Uint8 XOffset); }; XEnviron: class XEnviron : public XMapObject { public: Uint8 Effect,TimeOut; void CreateEnviron(Uint8 Type,Uint8 Y,Uint8 X,Uint8 TimeOut); }; XItem: class XItem : public XMapObject { public: void CreateItem(Uint8 Type,Uint8 Y,Uint8 X); }; And lastly, the entity move code. Only entities are capable of moving themselves. Uint8 XEntity::MoveEntity(Uint8 YOffset,Uint8 XOffset) { Uint8 NewY = Location[0] + YOffset, NewX = Location[1] + XOffset; if((NewY >= 0 && NewY < MAPY) && (NewX >= 0 && NewX < MAPX)) { XTile *Tile = GetTile(NewY,NewX); if(Tile->MapList != NULL) { XMapObject *MapObject = Tile->MapList; while(MapObject != NULL) { if(MapObject->MapObjectFlags & MAPOBJECT_SOLID) { printf("solid\n"); return 0; } MapObject = MapObject->NextMapObject; } } if(Tile->Flags & TILE_SOLID && EntityFlags & ENTITY_CLIPPING) { return 0; } this->MapObjectSetLocation(NewY,NewX); return 1; } return 0; } What is wierd, is that the bitwise operator always returns true when the MapObject is an Environ or an Item, but it works correctly for Entities. For debug I am using the printf "Solid", and also a printf containing the value of the flag for both Environs and Items. Any help is greatly appreciated, as this is a major bug for the small game I am working on.

SVN: Release branch headaches, how to merge in website revisions as and when cleared to go live?

- by Pete Duncanson

I need a sanity check here if we can, any ideas on correcting/changing the following are very welcome! We've been getting ourselves in knots of late with our SVN and are trying to correct it by putting a Trunk/Release system in place. We have a large website that we develop on and we store it all in SVN. Heres what we had in mind: We have trunk and a release branch All work gets checked into Trunk. When a feature is deemed ready for the next release it is merged into a Release branch. We only have one release branch and just tag "Latest" when we do a push to live We hope to be able to get all the files changed from Latest to Head to give us a zip that we can upload (any ideas on an easy way to do this via scripting?) So we set all this up and where very happy with ourselves. Except its not working and heres why. We work on lots a different features/fixes/problems at once and they don't all get nicely checked in feature complete (but always working at least). Then sometimes you have to wait for Clients to sign off. As a result you end up with revisions which are "ready for live" being scattered with ones which are "still being worked on" in trunk. That means that the completed revisions are not getting merged in sequentially but out of order. I thought SVN could handle this, clever little thing it is, but apparently not. Heres an example: Pete changes some CSS to make a new button look pretty (Revision 1) Dave add some CSS to the bottom of the same CSS file as Pete's for a new feature (Revision 2) Dave's mod gets the nod so he merges it into Release and commits it with a log message mentioning revision number and bug tracking id. Pete adds more buttons to finish this mod, no CSS changes here though (Revision 3) Pete then merges his mods (Revision 1 and 3) into the Head of Release (which has Daves merge in it) but this over-writes Daves CSS additions which now dissapear completely. This leads to the site being broken and the Release branch being pretty much useless. So we tried some other ideas like reverting Release back to "Latest" and then just merging in all the Revisions 1,2 and 3 in order. This worked fine until we had Revision 4 which was not ready for live and Revision 5 which was. Suddenly we are getting ourselves in knots again with exactly the same problem! Ok so take three. Revert to Latest, merge in Revision 5, then do any update back to Head. Tree conflicts galore! So thats a no no. I cracked in the end and built it all up manaually but its not something I want to do regular, ideally I want to script our deployment but can't while Release is in such a mess. HELP! What the heck are we doing wrong? I can't seem to find any solutions to this problem of wanting different none sequential Revisions in Release. If its not possible thats fine but how the heck are we meant to get stuff live easily. We can't branch for every single change, the site takes 30 minutes+ to check out it would take too long. Side note, we are using TortoiseSVN so can we keep command line examples to a minimum in any answers? Latest version of TSVN and SVN Version 1.6 so we have the funky merge tracking etc. EDIT: An excellent blog post which deals with the dev/release cycle (although using GIT but still relivant) thought everyone would like to read it if they found this question interesting. (http://nvie.com/git-model) EDIT 2: I wrote a blog post on how to show which branch you are working on in your website which others have asked me about (http://www.offroadcode.com/2010/5/14/which-svn-branch-are-you-working-on.aspx). Hope that helps. In the meantime we are looking at Kiln and hoping to make the switch next month (gulp!)

TableViewCell autorelease error

- by iAm

OK, for two days now i have been trying to solve an error i have inside the cellForRowAtIndex method, let start by saying that i have tracked down the bug to this method, the error is [CFDictionary image] or [Not a Type image] message sent to deallocated instance. I know about the debug flags, NSZombie, MallocStack, and others, they helped me narrow it down to this method and why, but I do not know how to solve besides a redesign of the app UI. SO what am i trying to do, well for this block of code, displays a purchase detail, which contains items, the items are in there own section, now when in edit mode, there appears a cell at the bottom of the items section with a label of "Add new Item", and this button will present a modal view of the add item controller, item is added and the view returns to the purchase detail screen, with the just added item in the section just above the "add new Item" cell, the problem happens when i scroll the item section off screen and back into view the app crashes with EXC_BAD_ACCESS, or even if i don't scroll and instead hit the back button on the navBar, still the same error. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case PURCHASE_SECTION: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch (indexPath.row) { case CATEGORY_ROW: cell.textLabel.text = @"Category:"; cell.detailTextLabel.text = [self.purchase.category valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case TYPE_ROW: cell.textLabel.text = @"Type:"; cell.detailTextLabel.text = [self.purchase.type valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case VENDOR_ROW: cell.textLabel.text = @"Payment:"; cell.detailTextLabel.text = [self.purchase.vendor valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case NOTES_ROW: cell.textLabel.text = @"Notes"; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; default: break; } break; } case ITEMS_SECTION: { NSUInteger itemsCount = [items count]; if (indexPath.row < itemsCount) { static NSString *itemsCellID = @"ItemsCell"; cell = [tableView dequeueReusableCellWithIdentifier:itemsCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:itemsCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } singleItem = [self.items objectAtIndex:indexPath.row]; cell.textLabel.text = singleItem.name; cell.detailTextLabel.text = [singleItem.amount formattedDataDisplay]; cell.imageView.image = [singleItem.image image]; } else { static NSString *AddItemCellID = @"AddItemCell"; cell = [tableView dequeueReusableCellWithIdentifier:AddItemCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddItemCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } cell.textLabel.text = @"Add Item"; } break; } case LOCATION_SECTION: { static NSString *localID = @"LocationCell"; cell = [tableView dequeueReusableCellWithIdentifier:localID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:localID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } cell.textLabel.text = @"Purchase Location"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; } default: break; } return cell; } the singleItem is of Modal Type PurchaseItem for core data now that i know what is causing the error, how do i solve it, I have tried everything that i know and some of what i dont know but still, no progress, please any suggestions as to how to solve this without redesign is my goal, perhaps there is an error i am doing that I cannot see, but if it's the nature of autorelease, than i will redesign.

Trouble recovering MySQL InnoDB database after server crash

- by Andy Shinn

I had a server crash due to a broken iSCSI link (the filesystem went into read-only mode). After repairing the link and rebooting the machine (CentOS 5 / MySQL 5.1), the MySQL server would not start and gave the following error: 100603 19:11:46 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql InnoDB: The log sequence number in ibdata files does not match InnoDB: the log sequence number in the ib_logfiles! 100603 19:11:46 InnoDB: Database was not shut down normally!

web grid server pagination trigger multiple controller call when changing page

- by Thomas Scattolin

When I server-filter on "au" my web grid and change page, multiple call to the controller are done : the first with 0 filtering, the second with "a" filtering, the third with "au" filtering. My table load huge data so the first call is longer than others. I see the grid displaying firstly the third call result, then the second, and finally the first call (this order correspond to the response time of my controller due to filter parameter) Why are all that controller call made ? Can't just my controller be called once with my total filter "au" ? What should I do ? Here is my grid : $("#" + gridId).kendoGrid({ selectable: "row", pageable: true, filterable:true, scrollable : true, //scrollable: { // virtual: true //false // Bug : Génère un affichage multiple... //}, navigatable: true, groupable: true, sortable: { mode: "multiple", // enables multi-column sorting allowUnsort: true }, dataSource: { type: "json", serverPaging: true, serverSorting: true, serverFiltering: true, serverGrouping:false, // Ne fonctionne pas... pageSize: '@ViewBag.Pagination', transport: { read: { url: Procvalue + "/LOV", type: "POST", dataType: "json", contentType: "application/json; charset=utf-8" }, parameterMap: function (options, type) { // Mise à jour du format d'envoi des paramètres // pour qu'ils puissent être correctement interprétés côté serveur. // Construction du paramètre sort : if (options.sort != null) { var sort = options.sort; var sort2 = ""; for (i = 0; i < sort.length; i++) { sort2 = sort2 + sort[i].field + '-' + sort[i].dir + '~'; } options.sort = sort2; } if (options.group != null) { var group = options.group; var group2 = ""; for (i = 0; i < group.length; i++) { group2 = group2 + group[i].field + '-' + group[i].dir + '~'; } options.group = group2; } if (options.filter != null) { var filter = options.filter.filters; var filter2 = ""; for (i = 0; i < filter.length; i++) { // Vérification si type colonne == string. // Parcours des colonnes pour trouver celle qui a le même nom de champ. var type = ""; for (j = 0 ; j < colonnes.length ; j++) { if (colonnes[j].champ == filter[i].field) { type = colonnes[j].type; break; } } if (filter2.length == 0) { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; } else { // Sans '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } else { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; }else{ filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } } options.filter = filter2; } var json = JSON.stringify(options); return json; } }, schema: { data: function (data) { return eval(data.data.Data); }, total: function (data) { return eval(data.data.Total); } }, filter: { logic: "or", filters:filtre(valeur) } }, columns: getColonnes(colonnes) }); Here is my controller : [HttpPost] public ActionResult LOV([DataSourceRequest] DataSourceRequest request) { return Json(CProduitsManager.GetProduits().ToDataSourceResult(request)); }

Trouble connecting to vsftpd on ubuntu server

- by littleK

I have installed Ubuntu Server 10.10 and I am using it to host a domain that I have. I am trying to set up FTP for the server, but I am running into some problems. I have successfully installed vsFTPd and I have opened up ports 20, 21 on my firewall. In my vsFTPd configuration, I have enabled SSL. Every time I try to connect to my server via FTP, I receive a "Connection Refused" error. I have had a little more success with SSL disabled, however the connection process will time out after the LIST command (but it does accept my authentication). Here is my vsFTPd configuration, the SSL stuff is at the bottom: # Example config file /etc/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. # # READ THIS: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's # capabilities. # # # Run standalone? vsftpd can run either from an inetd or as a standalone # daemon started from an initscript. listen=YES # # Run standalone with IPv6? # Like the listen parameter, except vsftpd will listen on an IPv6 socket # instead of an IPv4 one. This parameter and the listen parameter are mutually # exclusive. #listen_ipv6=YES # # Allow anonymous FTP?

How to make MVC 4 Razor Html.Raw work for assignment in HTML within script tags

- by Yarune

For a project I'm using jqote for templating in JavaScript and HTML generated by MVC 4 with Razor. Please have a look at the following code in HTML and Razor: <script id="testTemplate" type="text/html"> <p>Some html</p> @{string id = "<%=this.Id%>";}  @if(true) { @Html.Raw(@"<select id="""+id+@"""></select>") }  @if(true) { <select id="@Html.Raw(id)"></select> }  @Html.Raw(@"<select id="""+id+@"""></select>")  <select id="@Html.Raw(id)"></select>  <select id="<%=this.Id%>"></select> </script> The output is this: <script id="testTemplate" type="text/html">  <select id="<%=this.Id%>"></select>   <select id="<%=this.Id%>"></select>   <select id="<%=this.Id%>"></select>   <select id="<%=this.Id%>"></select>   <select id="<%=this.Id%>"></select>  </script> Now, the problem is with the second select under . One would expect the Html.Raw to kick in here but somehow it doesn't. Or Razor wants to HtmlEncode what's in there. The question is: Does anyone have an idea why? Is this a bug or by design? Without the script tags it works. But we need the script tags cause we need to template in JavaScript. Hardcoded it works, but we need to use a variable because this will not always be a template. Without the @if it works, but it's there, we need it. Workarounds These lines give similar good outputs: @if(true) { <select id= "@Html.Raw(id)"></select> } @if(true) { <select id ="@Html.Raw(id)"></select> } @if(true) { <select id @Html.Raw("=")"@Html.Raw(id)"></select> } We're planning to do this: <script id="testTemplate" type="text/html"> @{string id = @"id=""<%=this.Id%>""";} @if(true) { <select @Html.Raw(id)></select> } </script> ...to keep as to markup intact as much as possible.

Process spawned by exec-maven-plugin blocks the maven process

- by Arnab Biswas

I am trying to execute the following scenario using maven : pre-integration-phase : Start a java based application using a main class (using exec-maven-plugin) integration-phase : Run the integration test cases (using maven-failsafe-plugin) post-integration-phase: Stop the application gracefully (using exec-maven-plugin) Here is pom.xml snip: <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.2.1</version> <executions> <execution> <id>launch-myApp</id> <phase>pre-integration-test</phase> <goals> <goal>exec</goal> </goals> </execution> </executions> <configuration> <executable>java</executable> <arguments> <argument>-DMY_APP_HOME=/usr/home/target/local</argument> <argument>-Djava.library.path=/usr/home/other/lib</argument> <argument>-classpath</argument> <classpath/> <argument>com.foo.MyApp</argument> </arguments> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-failsafe-plugin</artifactId> <version>2.12</version> <executions> <execution> <goals> <goal>integration-test</goal> <goal>verify</goal> </goals> </execution> </executions> <configuration> <forkMode>always</forkMode> </configuration> </plugin> </plugins> If I execute mvn post-integration-test, my application is getting started as a child process of the maven process, but the application process is blocking the maven process from executing the integration tests which comes in the next phase. Later I found that there is a bug (or missing functionality?) in maven exec plugin, because of which the application process blocks the maven process. To address this issue, I have encapsulated the invocation of MyApp.java in a shell script and then appended “/dev/null 2&1 &” to spawn a separate background process. Here is the snip (this is just a snip and not the actual one) from runTest.sh: java - DMY_APP_HOME =$2 com.foo.MyApp > /dev/null 2>&1 & Although this solves my issue, is there any other way to do it? Am I missing any argument for exec-maven-plugin?

Fluent NHibernate - subclasses with shared reference

- by ollie

Edit: changed class names. I'm using Fluent NHibernate (v 1.0.0.614) automapping on the following set of classes (where Entity is the base class provided in the S#arp Architecture framework): public class Car : Entity { public virtual int ModelYear { get; set; } public virtual Company Manufacturer { get; set; } } public class Sedan : Car { public virtual bool WonSedanOfYear { get; set; } } public class Company : Entity { public virtual IList<Sedan> Sedans { get; set; } } This results in the following Configuration (as written to hbm.xml): <class name="Company" table="Companies"> <id name="Id" type="System.Int32" unsaved-value="0"> <column name="`ID`" /> <generator class="identity" /> </id> <bag cascade="all" inverse="true" name="Sedans" mutable="true"> <key> <column name="`CompanyID`" /> </key> <one-to-many class="Sedan" /> </bag> </class> <class name="Car" table="Cars"> <id name="Id" type="System.Int32" unsaved-value="0"> <column name="`ID`" /> <generator class="identity" /> </id> <property name="ModelYear" type="System.Int32"> <column name="`ModelYear`" /> </property> <many-to-one cascade="save-update" class="Company" name="Manufacturer"> <column name="`CompanyID`" /> </many-to-one> <joined-subclass name="Sedan"> <key> <column name="`CarID`" /> </key> <property name="WonSedanOfYear" type="System.Boolean"> <column name="`WonSedanOfYear`" /> </property> </joined-subclass> </class> So far so good! But now comes the ugly part. The generated database tables: Table: Companies Columns: ID (PK, int, not null) Table: Cars Columns: ID (PK, int, not null) ModelYear (int, null) CompanyID (FK, int, null) Table: Sedan Columns: CarID (PK, FK, int, not null) WonSedanOfYear (bit, null) CompanyID (FK, int, null) Instead of one FK for Company, I get two! How can I ensure I only get one FK for Company? Override the automapping? Put a convention in place? Or is this a bug? Your thoughts are appreciated.

Is SQL Server DRI (ON DELETE CASCADE) slow?

- by Aaronaught

I've been analyzing a recurring "bug report" (perf issue) in one of our systems related to a particularly slow delete operation. Long story short: It seems that the CASCADE DELETE keys were largely responsible, and I'd like to know (a) if this makes sense, and (b) why it's the case. We have a schema of, let's say, widgets, those being at the root of a large graph of related tables and related-to-related tables and so on. To be perfectly clear, deleting from this table is actively discouraged; it is the "nuclear option" and users are under no illusions to the contrary. Nevertheless, it sometimes just has to be done. The schema looks something like this: Widgets | +--- Anvils (1:1) | | | +--- AnvilTestData (1:N) | +--- WidgetHistory (1:N) | +--- WidgetHistoryDetails (1:N) Nothing too scary, really. A Widget can be different types, an Anvil is a special type, so that relationship is 1:1 (or more accurately 1:0..1). Then there's a large amount of data - perhaps thousands of rows of AnvilTestData per Anvil collected over time, dealing with hardness, corrosion, exact weight, hammer compatibility, usability issues, and impact tests with cartoon heads. Then every Widget has a long, boring history of various types of transactions - production, inventory moves, sales, defect investigations, RMAs, repairs, customer complaints, etc. There might be 10-20k details for a single widget, or none at all, depending on its age. So, unsurprisingly, there's a CASCADE DELETE relationship at every level here. If a Widget needs to be deleted, it means something's gone terribly wrong and we need to erase any records of that widget ever existing, including its history, test data, etc. Again, nuclear option. Relations are all indexed, statistics are up to date. Normal queries are fast. The system tends to hum along pretty smoothly for everything except deletes. Getting to the point here, finally, for various reasons we only allow deleting one widget at a time, so a delete statement would look like this: DELETE FROM Widgets WHERE WidgetID = @WidgetID Pretty simple, innocuous looking delete... that takes over 2 minutes to run, for a widget with no data! After slogging through execution plans I was finally able to pick out the AnvilTestData and WidgetHistoryDetails deletes as the sub-operations with the highest cost. So I experimented with turning off the CASCADE (but keeping the actual FK, just setting it to NO ACTION) and rewriting the script as something very much like the following: DECLARE @AnvilID int SELECT @AnvilID = AnvilID FROM Anvils WHERE WidgetID = @WidgetID DELETE FROM AnvilTestData WHERE AnvilID = @AnvilID DELETE FROM WidgetHistory WHERE HistoryID IN ( SELECT HistoryID FROM WidgetHistory WHERE WidgetID = @WidgetID) DELETE FROM Widgets WHERE WidgetID = @WidgetID Both of these "optimizations" resulted in significant speedups, each one shaving nearly a full minute off the execution time, so that the original 2-minute deletion now takes about 5-10 seconds - at least for new widgets, without much history or test data. Just to be absolutely clear, there is still a CASCADE from WidgetHistory to WidgetHistoryDetails, where the fanout is highest, I only removed the one originating from Widgets. Further "flattening" of the cascade relationships resulted in progressively less dramatic but still noticeable speedups, to the point where deleting a new widget was almost instantaneous once all of the cascade deletes to larger tables were removed and replaced with explicit deletes. I'm using DBCC DROPCLEANBUFFERS and DBCC FREEPROCCACHE before each test. I've disabled all triggers that might be causing further slowdowns (although those would show up in the execution plan anyway). And I'm testing against older widgets, too, and noticing a significant speedup there as well; deletes that used to take 5 minutes now take 20-40 seconds. Now I'm an ardent supporter of the "SELECT ain't broken" philosophy, but there just doesn't seem to be any logical explanation for this behaviour other than crushing, mind-boggling inefficiency of the CASCADE DELETE relationships. So, my questions are: Is this a known issue with DRI in SQL Server? (I couldn't seem to find any references to this sort of thing on Google or here in SO; I suspect the answer is no.) If not, is there another explanation for the behaviour I'm seeing? If it is a known issue, why is it an issue, and are there better workarounds I could be using?

How do I send an email with embedded images AND regular attachments in JavaMail?

- by Chris

Hi, I'd like to know how to build an SMTP multipart message in the correct order so that it will render correctly on the iPhone mail client (rendering correctly in GMail). I'm using Javamail to build up an email containing the following parts: A body part with content type "text/html; UTF-8" An embedded image attachment. A file attachment I am sending the mail via GMail SMTP (via SSL) and the mail is sent and rendered correctly using a GMail account, however, the mail does not render correctly on the iPhone mail client. On the iPhone mail client, the image is rendered before the "Before Image" text when it should be rendered afterwards. After the "Before Image" text there is an icon with a question mark (I assume it means it couldn't find the referenced CID). I'm not sure if this is a limitation of the iPhone mail client or a bug in my mail sending code (I strongly assume the latter). I think that perhaps the headers on my parts might by incorrect or perhaps I am providing the multiparts in the wrong order. I include the text of the received mail as output by gmail (which renders the file correc Message-ID: <[email protected]> Subject: =?UTF-8?Q?Test_from_=E3=82=AF=E3=83=AA=E3=82=B9?= MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_0_20870565.1274154021755" ------=_Part_0_20870565.1274154021755 Content-Type: application/octet-stream Content-Transfer-Encoding: base64 Content-ID: <20100518124021763_368238_0> iVBORw0K ----- TRIMMED FOR CONCISENESS 6p1VVy4alAAAAABJRU5ErkJggg== ------=_Part_0_20870565.1274154021755 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit <html><head><title>Employees Favourite Foods</title> <style> body { font: normal 8pt arial; } th { font: bold 8pt arial; white-space: nowrap; } td { font: normal 8pt arial; white-space: nowrap; } </style></head><body> Before Image<br><img src="cid:20100518124021763_368238_0"> After Image<br><table border="0"> <tr> <th colspan="4">Employees Favourite Foods</th> </tr> <tr> <th align="left">Name</th><th align="left">Age</th><th align="left">Tel.No</th><th align="left">Fav.Food</th> </tr> <tr style="background-color:#e0e0e0"> <td>Chris</td><td>34</td><td>555-123-4567</td><td>Pancakes</td> </tr> </table></body></html> ------=_Part_0_20870565.1274154021755 Content-Type: text/plain; charset=us-ascii; name=textfile.txt Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=textfile.txt This is a textfile with numbers counting from one to ten beneath this line: one two three four five six seven eight nine ten(no trailing carriage return) ------=_Part_0_20870565.1274154021755-- Even if you can't assist me with this, I would appreciate it if any members of the forum could forward me a (non-personal) mail that includes inline images (not external hyperlinked images though). I just need to find a working sample then I can move past this. Thanks, Chris.

Chaining CSS classes in IE6 - Trying to find a jQuery solution?

- by Mike Baxter

Right, perhaps I ask the impossible? I consider myself fairly new to Javscript and jQuery, but that being said, I have written some fairly complex code recently so I am definitely getting there... however I am now possed with a rather interesting issue at my current freelance contract. The previous web coder has taken a Grid-960 approach to the HTML and as a result has used chained classes to style many of the elements. The example below is typical of what can be found in the code: <div class='blocks four-col-1 orange highlight'>Some content</div> And in the css there will be different declarations for: (not actual css... but close enough) .blocks {margin-right:10px;} .orange {background-image:url(someimage.jpg);} .highlight {font-weight:bold;} .four-col-1 {width:300px;} and to make matters worse... this is in the CSS: .blocks.orange.highlight {background-colour:#dd00ff;} Anyone not familiar with this particular bug can read more on it here: http://www.ryanbrill.com/archives/multiple-classes-in-ie/ it is very real and very annoying. Without wanting to go into the merrits of not chaining classes (I told them this, but it is no longer feasible to change their approach... 100 hand coded pages into a 150 page website, no CMS... sigh) and without the luxury of being able to change the way these blocks are styled... can anyone advise me on the complexity and benefits between any of my below proposed approaches or possible other options that would adequately solve this problem. Potential Solution 1 Using conditional comments I am considering loading a jquery script only for IE6 that: Reads the class of all divs in a certain section of the page and pushes to an array creates empty boxes off screen with only one of the classes applied at a time Reads the applied CSS values for each box Re-applies these styles to the individual box, somehow bearing in mind the order in which they are called and overwriting conflicting instructions as required Potential Solution 2 read the class of all divs in a certain section of the page and push to an array Scan the document for links to style sheets Ajax grab the stylesheets and traverse looking for matching names to those in class array Apply styles as needed Potential Solution 3 Create an IE6 only stylesheet containing the exact style to be applied as a unique name (ie: class='blocks orange highlight' becomes class='blocks-orange-highlight') Traverse the document in IE6 and convert all spaces in class declarations to hyphens and reapply classes based on new style name Summary: Solution 1 allows the people at this company to apply any styles in the future and the script will adjust as needed. However it does not allow for the chained style to be added, only the individual style... it is also processor intensive and time consuming, but also the most likely to be converted into a plugin that could be used the world over Solution 2 is a potential nightmare to code. But again will allow for an endless number of updates without breaking Solution 3 will require someone at the companty to hardcode the new styles every time they make a change, and if they don't, IE6 will break. Ironically the site, whilst needing to conform to IE6 in a limited manner, does not need to run wihtout javascript (they've made the call... have JS or go away), so consider all jQuery and JS solutions to be 'game on'. Did I mention how much i hate IE6? Anyway... any thoughts or comments would be appreciated. I will continue to develop my own solution and if I discover one that can be turned into a jQuery plugin I will post it here in the comments. Regards, Mike.
