  • How do I render the scrollable regions of a canvas with IViewObject::Draw?

    - by nirvdrum
    Hi, I've been trying to render the entire canvas in an IWebBrowser2 control to a bitmap. IViewObject::Draw seems to be the most promising approach, but I can't get it to render anything that would requires a scroll to show. While I could automate the scrolling and stitch the images together, this would look weird with any fixed position elements. Is this even doable? Additionally, I've tried to set the controller's size to one that would allow the entire contents to display without needing to scroll, but Windows caps the max size to the current screen resolution, so that only gets me partially there. Any help would be much appreciated. I'm currently doing this in the context of Win7 and IE8, but I don't think that should matter much.

  • Jquery Validate Issue

    - by Thomas
    I'm using the Jquery validate plugin to validate a multi-step form like this one: http://jquery.bassistance.de/validate/demo/multipart/ Unfortunately, I can't seem to get it to work at all and there is a total lack of documentation to guide me through implemnetation. I think the accordian part of script is firing correctly because the bottom half of the form is being hidden and a 'next' button has been successfuly inserted. However, the form never validates or delivers an error message and it is impossible to move on to the next step. Check it out here: http://www.loftist.com/?page_id=78

  • What is an "incompletely constructed object"?

    - by Joonas Pulakka
    Goetz's Java Concurrency in Practice, page 41, mentions how this reference can escape during construction. A "don't do this" example: public class ThisEscape { public ThisEscape(EventSource source) { source.registerListener( new EventListener() { public void onEvent(Event e) { doSomething(e); } }); } } Here this is "escaping" via the fact that doSomething(e) refers to the enclosing ThisEscape instance. The book states: Publishing an object from within its constructor can publish an incompletely constructed object. This is true even if the publication is the last statement in the constructor. If the this reference escapes during construction, the object is considered not properly constructed. I don't quite get this. If the publication is the last statement in the constructor, hasn't all the constructing work been done before that? How come is this not valid by then? Apparently there's some voodoo going on after that, but what?

  • Ivy failed to resolve dependency : What to check, what to do ?

    - by fardon57
    Hi everyone, I'm using Ivy to resolve dependency in my very small project. It's the first time I'm doing that and it's more to learn as my project is very small. I had a problem 5 minutes ago, when trying to download log4j. My configuration is very basic, I have an ant task : <target name="resolve" description="--> retrieve dependencies with ivy"> <ivy:retrieve/> </target> and my Ivy.xml file is like this : <dependency org="javax.servlet" name="servlet-api" rev="2.5" /> <dependency org="log4j" name="log4j" rev="1.2.15" /> </dependencies> The problem is seems to happen when ivy tries to download jms 1.1 (I suppose it's needed for log4j) as I can see in the console : : ::::::::::::::::::::::::::::::::::::::::::::: [ivy:retrieve] :: FAILED DOWNLOADS :: [ivy:retrieve] :: ^ see resolution messages for details ^ :: [ivy:retrieve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:retrieve] :: javax.jms#jms;1.1!jms.jar [ivy:retrieve] :: com.sun.jdmk#jmxtools;1.2.1!jmxtools.jar [ivy:retrieve] :: com.sun.jmx#jmxri;1.2.1!jmxri.jar [ivy:retrieve] :::::::::::::::::::::::::::::::::::::::::::::: Is there anything I can do ? Thanks a lot guys. F

  • iPhone SDK: Transparent tableviewcell isn't transparent?

    - by Harkonian
    I have a UITableViewController that has a background image. I am setting the image for the tableview like this: [self.view setBackgroundColor: [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: @"background1.jpg"]]]]; The problem is, each of my custom tableview cells get the same background image--it's repeated in each cell. As a test, I tried making everything in my cell transparent with an alpha of 0.0, but even then although I can't see any of the labels in each cell, I still see the background image repeated in each cell: cell.backgroundColor = [UIColor clearColor]; cell.contentView.backgroundColor = [UIColor clearColor]; cell.contentView.alpha = 0.0; cell.alpha = 0.0; Any suggestions on how to get my table's background image to stop repeating in each cell would be appreciated!

  • Classic ASP to WCF using the Service Moniker

    - by Jab
    I am trying to consume a WCF logging service from classic ASP without deploy a Com wrapper. I found a method of doing so here. Here is the vb script, simplified. Dim addr addr = "service:mexAddress=""net.pipe://localhost/Services/Logging/LoggingManager/Mex""," _ & "address=""net.pipe://localhost/Services/Logging/LoggingManager/classic/""," _ & "contract=""ILoggingManagerClassic"", contractNamespace=""http://Services.Logging.Classic/""," _ & "binding=""NetNamedPipeBinding_ILoggingManagerClassic"", bindingNamespace=""http://Services.Logging.Classic/""" set objErrorLogger = GetObject(addr) Dim strError : strError = objErrorLogger.LogError("blahblah") This works on Server 2008, but fails with this error on Server 2003. Failed to do mex retrieval:Metadata contains a reference that cannot be resolved: net.pipe://localhost/Services/Logging/LoggingManager/Mex.. Only when running through ASP does it fail, a sample VBS file on the same machine using the same code works fine. I think it may be permission related, but don't know where to begin. Anyone have any ideas? EDIT - let me clarify that the WCF host is a windows service running as NETWORK SERVICE. If this belongs on server fault, a moderator can move it. I have an account there as well.

  • What is the best way to set up a PHP development environment on a Mac?

    - by Edward Tanguay
    When I do PHP, I use XAMPP to set up a development environment on Windows, then upload to Linux servers, works very well. I'm now passing on a PHP project to a person who has a Mac so he needs a local PHP dev environment. I noticed XAMPP has a version for Mac which I will recommend. But knowing that Mac is always a bit different, has anyone used any other easy PHP environment setup tool for the Mac, or I could even imagine that Mac solves this issue more elegantly by e.g. having a web server ready to go upon first boot etc. What is the best way to set up a PHP development environment on a Mac?

  • External Reference to Richfaces modal

    - by John
    Hi, I need to get a <rich:modalPanel id="mod1" .../> component to load an external page on "show" action, defined as: <a4j:commandButton value="link" id="l1" reRender="mod1" oncomplete="Richfaces.showModalPanel('mod1')"> <f:setPropertyActionListener target="#{mybean.someParam}" value="#{myOtherbean.someOtherparam}" /> </a4j:commandButton> . My first try was with <rich:modalPanel id="mod1"> <ui:include src="#{mybean.generateURL()"/> </rich:modalPanel> but it just throws me a 404 page not found error, typing the generated URL directly into the address bar works perfectly fine. Does anyone know what's causing the problem , or what's the correct way to do this? The system is running on seam/richfaces. Thanks!

  • Rsyslog mail module not working

    - by Henry-Nicolas Tourneur
    Hi *, I would like to email snort alerts from my Debian Lenny fw. Syslog is sending log messages from the firewalls to a central rsyslog. On my central rsyslog, I got something like : $ModLoad ommail $ActionMailSMTPServer server.company.local $ActionMailFrom [email protected] $ActionMailTo [email protected] $ActionExecOnlyOnceEveryInterval 1 $template mailSubject,"[SNORT] Alert from %hostname%" $template mailBody,"Snort message\r\nmsg='%msg%'" $ActionMailSubject mailSubject if $msg regexp 'snort[[0-9]]: [[0-9]:[0-9]:[0-9]].*' then ommail:;mailBody But I doesn't get any mails, I even can trigger snort with something like ping -s 1400, it logs things like following but still no mail ! 2010-01-08T09:25:58+00:00 Hostname snort[4429]: [1:499:4] ICMP Large ICMP Packet [Classification: Potentially Bad Traffic] [Priority: 2]: {ICMP} ip_dest - ip_src Any idea ?

  • How do I prevent windows opening on one of my desktops?

    - by frankster
    I have 2 monitors and a tv screen connected to my computer. The tv is angled so I can watch it in bed but is facing away from my desk (and usually switched off). Sometimes applications open on the monitor and I have to fiddle around with the "Move" menu option to bring them back to one of the screens I can see. I don't want to disable the tv as I will just have to reenable it when I want to watch something on it, so how can I prevent applications opening on the tv?

  • Using DNFS for test purposes

    - by rene.kundersma
    Because of other priorities such as bringing the first v2 Database Machine in Netherlands into production I did spend less time on my blog that planned. I do however like to tell some things about DNFS, the build-in NFS client we have in Oracle RDBMS since 11.1. What DNFS is and how to set it up can all be found here . As you see this documentation is actually the "Clusterware Installation Guide". I think that is weird, I would expect this to be part of the Admin Guide, especially the "Tablespace" chapter. I do however want to show what I did not find in the documentation that quickly (and solved after talking to my famous colleague "the prutser"): First, a quick setup: 1. The standard ODM library needs to be replaced with the NFS ODM library: [oracle@ocm01 ~]$ cp $ORACLE_HOME/lib/libodm11.so $ORACLE_HOME/lib/libodm11.so_stub [oracle@ocm01 ~]$ ln -s $ORACLE_HOME/lib/libnfsodm11.so $ORACLE_HOME/lib/libodm11.so After changing to this library you will notice the following in your alert.log: Oracle instance running with ODM: Oracle Direct NFS ODM Library Version 2.0 2. The intention is to mount the datafiles over normal NAS (like NetApp). But, in case you want to test yourself and use an exported NFS filesystem, it should look like the following: [oracle@ocm01 ~]$ cat /etc/exports /u01/scratch/nfs *(rw,sync,insecure) Please note the "insecure" option in the export, since you will not be able to use DNFS without it if you export a filesystem from a host. Without the "insecure" option the NFS server considers the port used by the database "insecure" and the database is unable to acquire the mount: Direct NFS: NFS3ERR 1 Not owner. path ocm01.nl.oracle.com mntport 930 nfsport 2049 3. Before configuring the new Oracle stanza for NFS we still need to configure a regular kernel NFS mount: [root@ocm01 ~]# cat /etc/fstab | grep nfs ocm01.nl.oracle.com:/u01/scratch/nfs /incoming nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 4. Then a so called Oracle-'nfstab' needs to be created that specifies what the available exports to use: [oracle@ocm01 ~]$ cat /etc/oranfstab server:ocm01.nl.oracle.com path:192.168.1.40 export:/u01/scratch/nfs mount:/incoming 5. Creating a tablespace with a datafile on the NFS location: SQL create tablespace rk datafile '/incoming/rk.dbf' size 10M; Tablespace created. Be sure to know that it may happen that you do not specify the insecure option (like I did). In that case you will still see output from the query v$dnfs_servers: SQL select * from v$dnfs_servers; ID SVRNAME DIRNAME MNTPORT NFSPORT WTMAX RTMAX -- -------------------- ----------------- --------- ---------- ------ ------ 1 ocm01.nl.oracle.com /u01/scratch/nfs 684 2049 32768 32768 But, querying v$dnfsfiles and v$dnfs_channels will now return any result, and indeed, you will see the following message in the alert-log when you create a file : Direct NFS: NFS3ERR 1 Not owner. path ocm01.nl.oracle.com mntport 930 nfsport 2049 After correcting the export: SQL select * from v$dnfs_files; FILENAME FILESIZE PNUM SVR_ID --------------- -------- ------ ------ /incoming/rk.dbf 10493952 20 1 Rene Kundersma Oracle Technology Services, The Netherlands

    I've added a WCF Service Library to a Silverlight project. But when I try calling a method on the service I get a CommunicationException complaining about accessing a service in a cross-domain way. I've tried adding both a crossdomain.xml and clientaccesspolicyfile.xml to the service library project, but it doesn't help. Any idea what I'm doing wrong?
