راه حلی برای مشکل: “FileNotFoundException” با استفاده از گیرنده بلند من.

I was working on a feature last week that would add some event receivers to a specific list instance. (من یک کمی در مورد آن گیرنده لیست بلاگ).

با استفاده از خط فرمان, من می توانم با قابلیت نصب بدون خطا (اما زیر را برای خطا مخفی). When I tried to deploy the feature on the site, MOSS complained of a "FileNotFoundException" خطا. 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’ و یا یکی از وابستگیهای آن بسته نیز. The system cannot find the file specified.

I know how to deliberately cause that error: don’t install the assembly in the GAC. اما, 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. اما, 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.

بعد, 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. اما … 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: ارزش نمی تواند تهی.

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! پس, 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. For some reason, I did not use the -force option when I installed the new project. این بار, I did actually, truly forget to copy this new project’s assembly into the GAC. به عنوان یک نتیجه, I received that "FielNotFoundException" خطا. این بار, I got it from stsadm, not when I tried to activate the feature via the web browser. پس, -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.

"A Freudian slip? What’s that?"

"Well, when we finished eating, the waitress came by and asked how we liked our meals. I meant say, ‘I loved the chicken breast’ but instead I said ‘I loved your breasts’. I was so embarrassed."

"Ah," his co-worker replied. "I had the same thing happen to me this weekend with my wife. We were eating breakfast I meant to ask her to pass the butter, but instead I screamed at her, ‘You ruined my life!'"

ID رویداد 1023: “ویندوز می تواند MSSCNTRS DLL ضد توسعه را بار نیست”

تکمیلی (04/08/08): I seem to have solved this problem. From the command line, I ran "c:\WINDOWS SYSTEM32 lodctr / R" در صحبت کردن در مورد مشکلات InstallShield یا ورود و که به نظر می رسد که آن را برای من حل شده.

من متوجه شدم که به تازگی, 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 cannot load extensible counter DLL UGatherer, the first DWORD in data section is the Windows error code.

Windows cannot load extensible counter DLL UGTHRSVC, the first DWORD in data section is the Windows error code.

ویندوز می تواند MSSCNTRS DLL ضد توسعه را بار نیست, the first DWORD in data section is the Windows error code.

If I drill into the details of one of those messages, من این را دریافت کنید:

منبع: Perflib

نوع: خطا

دسته: هیچ یک

ID رویداد 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 had been nagging me about performing an update for quite some time, so I jotted down the version I had installed (apparently "1.0.1 build 29996") and did the update. This upgraded me to v1.04. متاسفانه, it did not fix the issue.

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, پس … not such a great option.

The host operating system is Windows XP 64 ذره.

I don’t think this has always happened, but I don’t recall any particular event that might have led to it.

This is why I hate computers.

سریع & ساده: تغییر نام فایل آپلود شده با استفاده از شیرپوینت مدل شیء از طریق یک گیرنده رویداد

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

تکمیلی 2: در پروژه کنونی من, users always upload documents. به عنوان یک نتیجه, 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() گیرنده به نظر می رسد برای یک مقدار معتبر وجود دارد در واقع قبل از انجام تغییر نام دهید و پس از آن, 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()" روش. در عوض, استفاده می کنیم "MoveTo(…)". Here is a minimal bit of code to accomplish this:

 عمومی نادیده گرفتن از درجه اعتبار ساقط ItemAdded(SPItemEventProperties خواص)
        {
            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.

این یک نسخه مفید تر است که می کند همان چیزی است, but assigns the name of the file to "Title":

 عمومی نادیده گرفتن از درجه اعتبار ساقط ItemAdded(SPItemEventProperties خواص)
        {
            DisableEventFiring();

            // اختصاص عنوان این آیتم به نام خود فایل.
 // توجه: این وظیفه باید قبل از فایل خود را تغییر.
 // تلفن به روز رسانی() در SPFile به نظر می رسد به ابطال خواص در
 // از بعضی جهات.  Updates to "Title" تا که تغییر شکست خورده (و به روز رسانی() صدا)
 // در مقابل تغییر را به نام فایل منتقل شدند.
            properties.ListItem["Title"] = properties.ListItem.File.Name،;

            properties.ListItem.Update();

            SPFile F = properties.ListItem.File;

            // دریافت پسوند فایل.  ما نیاز داریم که بعد از.
 رشته spfileExt = جدید FileInfo(f.Name).گسترش;

            // تغییر نام فایل به ID قلم دوم از اقلام لیست و استفاده از پسوند فایل را به نگه داشتن
 // که بخشی از آن دست نخورده.
            f.MoveTo(properties.ListItem.ParentList.RootFolder.Url +
                "/" + properties.ListItem["ID"] + spfileExt);

            // مرتکب حرکت.
            f.Update();

            EnableEventFiring();
        }

URL اقدام سفارشی نیست برای ویژگی های جدید نمایش داده خواهد شد

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 (او گفت: او به عنوان نوشت: یک وبلاگ با استفاده از یک ابزار را درک نمی کنند).

امروز, 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, اما زمانی که من آن را به فعال (بدون خطا) آن را به سادگی می دهد تا در منوی کشویی.

I finally realized that I misspelled "SharePoint" در صفت محل <CustomAction> گره. This is the bad elements.xml file:

<?XML نسخه="1.0" پشتیبانی می کند="UTF-8" ?>

اون یکی دو ساعت طول کشید تا بفهمم 🙂

من آرامش را در این واقعیت است که برخی از روز در آینده, من قادر به گفتن با اعتقاد راسخ, "back in the day, من تا به حال به راه رفتن سه مایل تا تپه ای در برف (پابرهنه!) in order to deploy a custom feature to MOSS. You kids, شما نمی دانید که چه آسان شما آن را دارند! Get off my lawn!"

نمی توانید صبر کنید.

آمار وبلاگ

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, مثلا, 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, لطفا به من بگویید.

وضعیت فضاهای زنده به من بگویید: کل بازدید روز, 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. گوگل, MSDN لینک انجمن, غیره).

در برخی از راه, a "hit" آشکار است. اگر شما در حال خواندن این جمله در حال حاضر, تو تقریبا قطعا به عنوان یک ضربه واحد ثبت نام.

RSS is a little confusing. On one hand, I see individual RSS hits all day long. اما, I also see RSS "sweeps". A sweep is when I see 20 یا 30 RSS hits all within a one or two second window. I assume these are automated things like google checking in on my site, مرورگرهای مردم شاید دیگر … مطمئن نیست. They are definitely some kind of automated process. I cannot tell, اما, 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 بازدید کننده در هر روز خودکار.

در به اعداد!

من وبلاگ من برای اولین بار در ژوئیه 27 نوشت, 2007.

من تقریبا نوشته شده است 60 نوشته های وبلاگ از آن زمان به بعد, بیش از 50 که از آن به طور مستقیم به شیرپوینت.

یکشنبه صبح با مزه: “آره, آره, آره. اه, اه, اه.”

حدود شش سال پیش, my four-year-old son and I were upstairs watching a Discovery channel "shark attacks" ویژه (احتمالا این یکی). 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, مثلا, any 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.

پس, 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. اما, I had misinterpreted his excitement. He was not worried about the girl at all. در عوض, 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 🙂 از طرفی, 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. I read 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").

به هر حال, 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." البته, 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, آره, آره. اه, اه, blah.".

خیلی برای آن 🙂

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

تغییر نمایش بر اساس شناسه کاربر در فرم InfoPath

ما یک فرم InfoPath ایجاد شده بود با نمایش های مختلف برای حمایت از یک استخدام جدید / on-boarding process. When the company hires a new person, بخش فناوری اطلاعات و گروه های دیگر نیاز به اقدام (تنظیم حقوق و دستمزد, دسترسی به برنامه های کاربردی مناسب را فعال کنید, قرار دادن یک میز, غیره). We use on form but a different view of the form for each of those functions.

At this company, most of the people involved in the business process are IT-savvy, so when they access the form, their default view is a "menu" view with buttons that direct them to their specific function. اما, we needed to simplify things for the new hire’s direct manager. This person should not see any of the IT related stuff. در واقع, she should see just one view of the form and not even have an option to see the other views.

In our case, that direct manager’s account is directly tied to the form courtesy of a contact selector (which I am always wanting to call a "people picker" for some reason).

The steps are as follows:

1. In design mode, go to Tools -> گزینه های فرم -> Open and Save.

2. Select "rules".

3. Create a new rule whose action is "switch to view" and whose condition leverages the userName() تابع.

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 (in my environment anyway) returns the domain and user ID, as in "domain\pagalvin". This prevents us from doing a straight-forward equality condition since AccountID ("domain\pagalvin") will never equal userName() ("pagalvin").

We can get around this using the "contains" operator: AccountID contains userName().

We can take it further and pre-pend a hard-coded domain in front of the userName() function to get our equality check and eliminate the risk of a false positive on the contains operator.

We would have REALLY like to automatically switch view for other users based on their AD security group membership. مثلا, when a member of the "IT Analytics" group accesses the form, 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", pass it the userName() and return back true or false. Does anyone have any other, more clever idea? Is there any SharePoint function we can leverage from InfoPath to make that determination?

به طور تصادفی با اضافه کردن کد به فرم InfoPath; عمدا از بین بردن آن

در هنگام کار با دکمه های فرم, we often add rules. You access the rules editor from the properties of the button.

وقتی که با کلیک در اطراف سرعت, it’s easy to accidentally click on "Edit Form Code" instead of "Rules …".

اولین بار من این را, I canceled out of the code editor. اما, زمانی که من سعی کردم به انتشار فرم در حالی که کمی بعد, it required that I publish as an "Administrator-approved form template (پیشرفته)". 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.

امروز, I did it again. این بار, من زمان کمی بیشتر در دست من بود و متوجه شد که شما به راحتی می توانید این کار را لغو.

رفتن به:

ابزار -> گزینه های فرم -> برنامه نویسی: "Remove Code"

این کار بسیار ساده تر از آن.
