Soluzzjoni għall-problema: “FileNotFoundException” Bil Riċevitur Karatteristika Tiegħi.

I was working on a feature last week that would add some event receivers to a specific list instance. (I blogged ftit dwar dak riċevitur lista hawn).

Bl-użu kmand tal-linja, I tista 'tinstalla l-karatteristika bl-ebda żball (imma ara hawn taħt għal-iżball moħbija). When I tried to deploy the feature on the site, MOSS complained of a "FileNotFoundException" żball. This blog entry describes how I solved it.

This is the error that MOSS showed me in the web browser:

Feature ‘b2cb42e3-4f0a-4380-aaba-1ef9cd526f20’ could not be installed because the loading of event receiver assembly "xyzzyFeatureReceiver_0" failed: System.IO.FileNotFoundException: Could not load file or assembly ‘xyzzyFeatureReceiver_0’ or one of its dependencies. The system cannot find the file specified.

I know how to deliberately cause that error: don’t install the assembly in the GAC. Iżda, it was in the GAC. I normally install assemblies into the GAC by dragging them into the c:\windows\assembly folder using windows explorer. I’ve never felt 100% comfortable doing that because I always thought that gacutil existed for a reason … so I tried that. It made no difference.

I searched the Internets and found this post: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2243677&SiteID=1

The poster happened to be using the same root bit of code (from the Inside WSS book from this list) so that was a hopeful sign. Madankollu, the suggestion of decorating the assembly with an [assembly: ] directive didn’t make sense to me. I tried it anyway and I was right. It made no difference.

Then I noticed that my class definition was not public. I made it public and that made no difference.

Li jmiss, I went to the trouble of enabling the "assembly bind failure log" (following the helpful and accurate instructions provided) and this is where things started to get interesting. That log shows me that the runtime is searching everywhere on that server for my assembly. It even appears to be searching for it in my medicine cabinet. Iżda … it won’t search for it in the GAC.

I put on my winter jacket and go searching the Internets again and find that someone has had this problem too. The lengthy discussion in that posting peters off into nothing and I can’t find a solution.

I move my assembly into one of the places the log claims it’s searching and I make a little more progress. I’m rewarded with a new error in the browser when I try to activate the feature:

Failed to create feature receiver object from assembly "xyzzyFeatureReceiver_0", type "Conchango.xyzzyFeatureReceiver" for feature b2cb42e3-4f0a-4380-aaba-1ef9cd526f20: System.ArgumentNullException: Valur ma jistax ikun null.

Time for one last trip to the Internets!

This time I find out, predictably enough, that MOSS issues this error because the assembly is not in GAC.

I want to get something positive out of this and try to feel a little proud that I’ve created the Fugitive of MSIL assemblies, but it’s not working. I’m just plain annoyed. I find myself muttering "chicken or the egg" under my breath.

I finally decide to punt. I create an entirely new project and copy/paste the code from the incredible-cloaked-from-the-GAC-assembly non-working project over to this new project. (I look for a build flag called something like "hide from assembly binding if installed in the GAC" but can’t find one).

I install the feature and activate it and … it works! Allura, after all that, I had to basically ‘reboot’ my project. This is another reason why I hate computers.

I did learn something useful from this. I had been installing features using the stsadm command line all day long and been using the "-force" option out of habit. Għal xi raġuni, I did not use the -force option when I installed the new project. Din id-darba, I did actually, truly forget to copy this new project’s assembly into the GAC. Bħala riżultat, I received that "FielNotFoundException" żball. Din id-darba, I got it from stsadm, not when I tried to activate the feature via the web browser. Allura, -force actually plays two roles. It allows you to re-install an existing feature. It also allows you to install a buggy feature that cannot work at runtime by suppressing the error. It probably says as much in the help somewhere but I never noticed it.

Event ID 1023: “Windows ma tista 'tagħbija MSSCNTRS extensible DLL counter”

UPDATE (04/08/08): I seem to have solved this problem. From the command line, I ran "c:\twieqi system32 lodctr / R" kif kull dħul jitkellem dwar problemi InstallShield u li jidher li solvuti għalija.

I ndunat li dan l-aħħar, my desktop/server fan never turns off. I know it used to turn off. I took a moment to check it out noticed that the a VMware process was running a consistent 20% utilization on one of the CPU’s. I checked the event log and saw these errors in the application log happening dozens of times per minute:

Windows ma tista 'tagħbija extensible UGatherer DLL counter, l-ewwel DWORD fit-taqsima tad-data huwa l-kodiċi żball Windows.

Windows ma tista 'tagħbija extensible UGTHRSVC DLL counter, l-ewwel DWORD fit-taqsima tad-data huwa l-kodiċi żball Windows.

Windows ma tista 'tagħbija MSSCNTRS extensible DLL counter, l-ewwel DWORD fit-taqsima tad-data huwa l-kodiċi żball Windows.

Jekk I drill fid-dettalji ta 'wieħed minn dawk il-messaġġi, I nikseb dan:

Sors: Perflib

Tip: Error

Kategorija: Xejn

Event ID 1023

I did some research and there was some indication it could be a permission problem in terms of access to the DLLs in question. I played around with that stuff but could not affect things in a positive way so I gave up on that.

VMware kienet nagging me dwar jwettqu aġġornament għal żmien pjuttost twil, so I jotted-verżjoni kelli installat (apparently "1.0.1 build 29996") and did the update. This upgraded me to v1.04. Sfortunatament, hija ma tiffissa l-kwistjoni.

I can stop the insane number of messages going to my application log if I shut down a service named "VMware Authorization Service". This prevents me from using the VMware software, hekk … not such a great option.

Is-sistema operattiva ospitanti hija Windows XP 64 bit.

I ma naħsibx li dan dejjem ġara, imma jien ma recall kwalunkwe każ partikolari li setgħet wasslet għal dan.

Dan huwa għaliex ddejjaqni kompjuters.

Quick & Easy: Semmi File Uploaded Jużaw Object Model SharePoint permezz ta 'Receiver Event

UPDATE: This works but there are significant limitations which are described in the comments. This may still be useful in some cirumstances.

UPDATE 2: Fil-proġett kurrenti tiegħi, users always upload documents. Bħala riżultat, I don’t run into a problem where MS Word is running and thinks that the file was renamed on it. I did run into a problem, "the file was modified by someone else" and solved this via a simple semaphore type flag. Users need to change a meta data field from its default value to something else. The itemupdated() riċevitur jistenna għal valur validu hemm qabel fil-fatt twettaq il semmi mill-ġdid u minn dakinhar, I have not had any problems. Your mileage may vary.

I have a client requirement to change the name of files uploaded to a specific document library to conform with a particular naming convention. The API does not provide a "rename()" metodu. Minflok, nużaw "MoveTo(…)". Here is a minimal bit of code to accomplish this:

 pubbliku override null ItemAdded(SPItemEventProperties proprjetajiet)
        {
            SPFile f = properties.ListItem.File;

            f.MoveTo(properties.ListItem.ParentList.RootFolder.Url + "/xyzzy.doc");
            f.Update();

        }

The only tricky bit is the "properties.ListItem.ParentList.RootFolder.Url". The MoveTo() method requires a URL. That mashed up string points me to the root folder of my current document library. This allows me to avoid any hard coding in my event receiver.

Din hija verżjoni aktar utli li ma l-istess ħaġa, but assigns the name of the file to "Title":

 pubbliku override null ItemAdded(SPItemEventProperties proprjetajiet)
        {
            DisableEventFiring();

            // Jassenja l-titolu ta 'din il-partita għall-isem tal-fajl innifsu.
 // NOTA: Din il-ħidma għandha sseħħ qabel we jimmodifika l-file nnifsu.
 // Sejħat aġġornament() fuq il-SPFile jidher li tinvalida l-proprjetajiet
 // xi sens.  Updates to "Title" naqset sakemm dik il-bidla (u l-aġġornament() sejħa)
 // tmexxew quddiem il-bidla għall-isem ta 'fajl.
            properties.ListItem["Title"] = Properties.ListItem.File.Name;

            properties.ListItem.Update();

            SPFile f = properties.ListItem.File;

            // Niżżel l-estensjoni tal-fajl.  Għandna bżonn li aktar tard.
 string spfileExt = ġdid File Info(f.Name).Estensjoni;

            // Semmi mill-ġdid l-fajl lill ID-oġġett lista u jużaw l-estensjoni fajl biex iżommu
 // li intatta parti minnu.
            f.MoveTo(properties.ListItem.ParentList.RootFolder.Url +
                "/" + properties.ListItem["ID"] + spfileExt);

            // Jimpenjaw il-moviment.
            f.Update();

            EnableEventFiring();
        }

Azzjoni Custom URL mhux se display għall-karatteristika ġdida

I’m still in the habit of crafting my feature XML files by hand since it’s all quite new to me. I don’t want to rely on a front-end tool that does stuff I don’t understand (huwa qal kif hu kiteb blog dħul użu ta 'għodda hu ma jifhimx).

Illum, I was trying to add a custom action to the site settings but it just wouldn’t show up. I could install the feature and see it in the site features, iżda meta I attivat (mingħajr żball) hija sempliċement mhux se juru fuq il-menu drop-down.

I finally realized that I misspelled "SharePoint" fil-attribut Location tal- <CustomAction> node. This is the bad elements.xml file:

<?xml Verżjoni="1.0" encoding="UTF-8" ?>
<Elementi xmlns="http://schemas.microsoft.com / Sharepoint /">
  <CustomAction
 Id="SiteActionsToolbar"
 GroupId="SiteActions"
 Post="Microsoft.Sharepoint.StandardMenu"
 Sekwenza="100"
 Titolu="Hello!"
 Deskrizzjoni="Azzjoni menu Custom miżjud permezz ta 'karatteristika."
 ImageUrl="_layouts / stampi / menuprofile.gif">

    <UrlAction Url="http://www.xyzzy.com"/>

  </CustomAction>
</Elementi>

Tajba:

<?xml Verżjoni="1.0" encoding="UTF-8" ?>
<Elementi xmlns="http://schemas.microsoft.com / Sharepoint /">
  <CustomAction
 Id="SiteActionsToolBar"
 GroupId="SiteActions"
 Post="Microsoft.SharePoint.StandardMenu"

 Deskrizzjoni="Azzjoni menu Custom miżjud permezz ta 'karatteristika."
    >
    <UrlAction Url="http://www.xyzzy.com"/>
  </CustomAction>
</Elementi>

That one took me a good two hours to figure out 🙂

I jieħdu solace fil-fatt li xi jum fil-futur, I ser tkun tista 'tgħid mal-kundanna, "back in the day, I kellhom jimxu tliet mili up għoljiet fil-borra (barefoot!) in order to deploy a custom feature to MOSS. You kids, inti ma tkunx taf kif faċli ikollok! Get off my lawn!"

Ma tistax tistenna.

Blog Stats

I thought some people might be interested in my blog’s statistics. You can use mine as a benchmark to compare your own.

I’m running my blog on windows live spaces. They collect stats for me and I don’t know any way to control that. It’s good as far as it goes, but it’s fairly limited in that I can’t do much actual analysis with it. I’d love, per eżempju, to be able to generate a listing of my most frequently hit posts but I can’t do that without a prohibitive manual process. If someone knows better, jekk jogħġbok għidli.

Status spazji Live tell me: hits totali għall-jum, total hits for the week and total hits since day zero. It also tells me what people did to get to my blog (e.g. google, MSDN link forum, eċċ).

F'xi metodi, a "hit" huwa ovvju. Jekk qed taqra dan sentenza dritt issa, inti stajt kważi ċertament reġistrat bħala hit waħda.

RSS is a little confusing. On one hand, I see individual RSS hits all day long. Iżda, I also see RSS "sweeps". A sweep is when I see 20 jew 30 RSS hits all within a one or two second window. I assume these are automated things like google checking in on my site, maybe other people’s browsers … mhux ċert. They are definitely some kind of automated process. I cannot tell, madankollu, how many of my total hits are automated and how many have an actual human on the other side. I would guess at least 100 hits kuljum huma awtomatizzati.

Fuq in-numri!

I kiteb l-ewwel dħul blog tiegħi fuq Lulju 27, 2007.

Ktibtu madwar 60 blog entries minn dakinhar, aktar minn 50 li direttament relatati ma SharePoint.

I bdew li jżommu rekord ta 'hits tiegħi spreadsheet fuq bażi ta' kuljum fl-aħħar ta 'Settembru.

Ħadd filgħodu Funny: “Yeah, yeah, yeah. Blah, blah, blah.”

Madwar sitt snin ilu, my four-year-old son and I were upstairs watching a Discovery channel "shark attacks" speċjali (possibilment dan wieħed). He was very young at the point and I was always worried what he might see on a show like this and how he might take it. I didn’t want him to develop, per eżempju, kwalunkwe special fears of the water or blab something inappropriate to his friends and possibly cause his baby friend network to come crashing down.

Discovery handles these kinds of subjects very well. It’s not about creating a fear of something, but rather to show how unusual it is for sharks to attack humans.

Allura, we’re watching it and there is this one particularly scary attack involving a small girl. As Discovery is building the drama of the attack, my son (who has always been extremely jumpy anyway), is getting very excited. I make some noises about how unusual it is for sharks to attack people, and how bad the poor girl must feel. I’m trying to explain that people recover from these events and become stronger for it. Madankollu, I had misinterpreted his excitement. He was not worried about the girl at all. Minflok, while clapping his hands, he tells me, "The sharks love it! It’s terrific. It’s wonderful. Its a DREAM COME TRUE!"

I thought this was hilarious, but also very disturbing. On the one hand, I was glad — even a little proud — that he could have strong empathic feelings, cross-species though they may be. As humans, we need to develop our "empathic muscles" so speak or you’ll end up like this guy 🙂 On the other hand, he was feeling cross-species empathy toward a species who was exhibiting behavior inimical to his own. I was really struggling with this when the narrator used the word "paradigm". My son picked up on that and asked me what that meant.

That’s not such an easy word to describe to a four year old, but I gave it a try. When I think of the word "paradigm", Thomas Kuhn is never far from my thoughts. Naqra The Structure of Scientific Revolutions back at Lafayette and for better or for worse, the word "paradigm" is pregnant with extra meaning for me. (Sort of like the word "contact" after hearing a Movie Phone voice tell me where I could see that movie [I thought the book was better]; I always say to myself, "CONTACT!" whenever I see or hear someone say "contact").

Xorta waħda, I’m trying to explain to him a Kuhnian definition, that it’s "a historical movement of thought" and that it’s a "way of thinking with a number of built-in assumptions that are hard to escape for people living at that time." Of course, you can’t talk like to a four-year old, so I’m trying to successively define it to smaller pieces and feeling rather proud of myself as I do so. (I just knew that someone outside of college would care that I had read Kuhn!).

I’m just warming to the task when he interrupts me. Waving his hand in my general direction and never taking his eyes off another brutal shark attack, he just says, "Yeah, yeah, yeah. Blah, blah, blah.".

So much for that 🙂

At that point, I decided to run away, rhetorically speaking, sit back, and enjoy watching sharks attack humans with my son.

Jaqilbu View View Ibbażat fuq User ID f'forma InfoPath

Kellna żviluppat formola InfoPath bl-opinjonijiet multipli biex tappoġġja kiri ġdida / on-boarding process. When the company hires a new person, IT dipartiment u gruppi oħra jeħtieġu li jieħdu azzjoni (stabbilit payroll, jippermettu aċċess għall-applikazzjonijiet xierqa, jillokalizza desk, eċċ). We use on form but a different view of the form for each of those functions.

Fuq din il-kumpanija, maġġoranza tal-persuni involuti fil-proċess tan-negozju IT-sofistikati, hekk meta jaċċessaw il-formola, their default view is a "menu" view with buttons that direct them to their specific function. Madankollu, we needed to simplify things for the new hire’s direct manager. This person should not see any of the IT related stuff. Fil-fatt, hi għandha tara wieħed biss minħabba l-forma u lanqas l-għażla li tara l-opinjonijiet l-oħra.

Fil-każ tagħna, dak il-kont manager dirett huwa direttament marbut ma l-forma korteżija ta ' kuntatt selettur (which I am always wanting to call a "people picker" għal xi raġuni).

Il-passi huma li ġejjin:

1. Fil-modalità disinn, mur Tools -> Formola Għażliet -> Open u Save.

2. Select "rules".

3. Create a new rule whose action is "switch to view" u li l-kondizzjoni tiggwida l-Username() funzjoni.

Username() returns the "simple" user name without the domain. If I log into SharePoint with credentials "domain\pagalvin", Username() returns "pagalvin".

The contact selector provides three bits of information for a contact. The "AccountID" portion is most useful for this scenario. The only thing that makes this even a little bit of challenge is that the contact selector (fl-ambjent tiegħi xorta) jirritorna l-dominju u user ID, as in "domain\pagalvin". This prevents us from doing a straight-forward equality condition since AccountID ("domain\pagalvin") qatt se ugwali username() ("pagalvin").

We can get around this using the "contains" operatur: AccountID fih Username().

Aħna tista 'tieħu aktar u pre-pend domain hard-kodifikati quddiem il-username() jiffunzjonaw biex tikseb l-ugwaljanza tagħna kontroll u jeliminaw ir-riskju ta 'pożittiv falz fuq l-operatur fih.

We would have REALLY like to automatically switch view for other users based on their AD security group membership. Per eżempju, when a member of the "IT Analytics" grupp aċċessi l-forma, automatically switch to the IT Analytics view. We didn’t have time to implement it, but my first thought is to create a web service that would have a method like "IsMemberOfActiveDirectorySecurityGroup", tgħaddiha l-Username() and return back true or false. Does anyone have any other, aktar idea għaqlija? Is there any SharePoint function we can leverage from InfoPath to make that determination?

</aħħar>

Aċċidentalment Żieda Kodiċi li Formola InfoPath; Deliberatament tneħħih

Meta taħdem bl-buttuni fuq formola, we often add rules. You access the rules editor from the properties of the button.

Meta tikklikkja madwar malajr, it’s easy to accidentally click on "Edit Form Code" instead of "Rules …".

L-ewwel darba I ma 'dan, I canceled out of the code editor. Madankollu, meta I ppruvaw li tippubblika l-forma filwaqt li ftit aktar tard, it required that I publish as an "Administrator-approved form template (avvanzat)". I didn’t actually do any programming and I absolutely didn’t want to go through an unnecessary approval process. I was in a bit of panic at the time due to time constraints. To get past it, I simply restored a previous backup and continued. I had recently seen some blog posts about people going into the form’s XML to tweak things and I was afraid I would have to do something similar.

Illum, I did it again. Din id-darba, I kellhom ftit aktar ħin fuq l-idejn tiegħi u sabet li inti tista 'faċilment teqred dan.

Mur:

Tools -> Formola Għażliet -> Programmazzjoni: "Remove Code"

Hija ma jiksbu ħafna eħfef minn dak.
