I receive a handful of messages from individuals via the built-in "send a message" function Microsoft provides with live spaces (which also hosts my blog) every month.
About one third of the time, those users have secured their live spaces account such that I cannot reply. This is some kind of anti-spam feature I assume.

როდესაც ვმუშაობთ ღონისძიება მიმღები და სხვა კოდი, რომელიც ეხება ამ SharePoint სია ნივთები მეშვეობით ობიექტის მოდელი, მე ხშირად უშვებენ შეცდომებს, რომ წარმოქმნის ეს შეცდომა at runtime:
შეცდომა და გაშვებული ღონისძიება მიმღები Conchango.xyzzyEventReceiver in xyzzy, მობილური = 1.0.0.0, კულტურის = ნეიტრალური, PublicKeyToken = 0dc50a750396c3ac. Additional information is below. : Value does not fall within the expected range.
I think this is a fairly generic error that is potentially caused many different ways. თუმცა, one simple explanation is that I’m referencing a field incorrectly. If the name of the field is "Due Date", I must reference it like this in an event receiver:
properties.ListItem["Due Date"]
When I misspell or use the wrong case when referencing the field, SharePoint generates the above mentioned runtime error. მაგალითად, this is wrong:
properties.ListItem["due Date"]

ჩვენ შეგვიძლია, უნდა და არ შევქმნათ მრავალი ხედვა SharePoint სიები (დოკუმენტის ბიბლიოთეკების, საბაჟო სიები, და ა.შ.). SharePoint always lists available views in alphabetical order. We cannot change this using out of the box functionality. If it can be done via customization (და მე არ ვარ დარწმუნებული, რომ ეს შეიძლება), it’s far to technical for your typical end user.
If you want to control the order in which SharePoint lists available views, simply prepend a number or letter to the view name, , როგორც in:
1 – By Material Type
2 – All Documents
3 – Due Date-ან-
A – By Material Type
B – All Documents
C – Due Date
I have also created views whose purpose is strictly to feed a KPI. I have been following this naming convention:
Z_KPI_[აღწერა]
That causes my "KPI" views to appear at the bottom of the list.

As a parent, somewhere along the line I discovered the "When I was a little boy" trick.
My son, probably four or five at the time, was playing a balloon and like most little boys that play with balloons, he popped it. He was very upset. The world had come to an end. I said to him, "when I was little boy, I had a balloon and it popped and eventually, I got a new balloon." It seemed to help him cope with his loss and led to a fun talk about what it was like when I was a little boy.
That worked well as a consolation technique and I used it a several times over the next period of time. I did get into trouble once when his Monster Rancher 3 creature died. I talked about how my dog, Prince, had died in a car accident. ამჯერად, his response was, "Now I feel bad about two things!" I shied away from using the "when I was a little boy" technique for consolation after that.
Before the dead dog incident, თუმცა, I had also started to use the technique to convince him to do chores. "When I was a little boy, I had to go out and get the newspaper", "clean my room", "get Mommy her coffee cup", და ა.შ..
This too was pretty successful for a while, but he started to increasingly rebel against the tyranny of my childhood. One event, კერძოდ, marked the end. I told him to bring the garbage cans from curb back to the garage. He argued and I responded, "When I was a little boy, I had to take the garbage back to the garage." He responded, "Oh yeah! Well when you were a little boy, that was STUPID!".

განახლების (02/29/08): ეს ახალი codeplex პროექტის ჩანს, რომ უზრუნველყოს მეთოდი უზრუნველყოფის ინდივიდუალური სვეტები: http://www.codeplex.com/SPListDisplaySetting. If you have any experience working with it, გთხოვთ დატოვოთ კომენტარი.
ფორუმი პლაკატები ხშირად ვთხოვთ კითხვა მსგავსი: "I have a manager view and and a staff view of a list. How do I secure the manager view so that staff can not use it?"
ისინი ასევე ხშირად ვთხოვთ დაკავშირებული კითხვა: "I want to secure a specific metadata column so that only managers may edit that column while others may not even see it."
These answers apply to both WSS 3.0 და MOSS:
There are several techniques one can follow to meet these kinds of security requirements. Here’s what I can think of:
არა იმ პარამეტრების მართლაც რომ დიდი, მაგრამ არსებობს სულ ცოტა გზა დაიცვას, თუ თქვენ უნდა, მაშინაც კი, თუ ეს რთული.
შენიშვნა: თუ თქვენ დაცემას რომელიმე ამ ბილიკები, don’t forget about "Actions -> Open with Windows Explorer". You want to be sure that you test with that feature to make sure that it doesn’t work as a "back door" და დაამარცხებს თქვენი უსაფრთხოების სქემა.
თუ თქვენ გაქვთ სხვა იდეები ან გამოცდილებას უზრუნველყოფის სვეტები და შეხედულების, გთხოვთ მომაწოდეთ ან დატოვონ კომენტარი და მე განაახლოს ეს განთავსებას, როგორც შესაბამისი.

თუ თქვენ ხელით კოდირება ADF ფაილი და აკეთებს უამრავ კოდი / იმპორტი / ტესტი ციკლის, use the version number to make your life easier.
მე სიძულვილის ვაღიაროთ ეს, მაგრამ სანამ ამ კვირაში, I was always deleting the ADF and re-importing it. This would break my business data columns and make me re-wire them. All unnecessary.
File this under "it’s obvious once you see it".
მაგალითი:
<LobSystem
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.microsoft.com/office/2006/03/BusinessDataCatalog BDCMetadata.xsd" გაცნობის="WebService" მობილური="1.2.0.0" სახელი="xyzzyDocumentReview" xmlns="http://schemas.microsoft.com/office/2006/03/BusinessDataCatalog">
Change that version and re-import and the existing business data column uses the updated version automatically with no additional configuration required.

In my on-going attempts at providing a more useful lookup column using BDC, I hit a wall with the BDC picker. If you haven’t see it, the BDC picker is similar to a people picker except that it works with columns of type "business data".
You access the picker by clicking on the open book icon of a business data column as shown:
The above image shows a business data column called "Master Document Id". That column is connected, via BDC, to a web service. The web service returns two columns of information: Document ID and Title. The business purpose here is to provide a "this document is based on" ფუნქცია. Users select a "master" document and when they save, an event receiver copies meta data fields from the referenced master.
სტანდარტულად, the BDC picker looks like this when I search for a document whose ID = "38":
That’s helpful, but not good enough. People don’t think in terms of IDs, they think in terms of titles and/or other meta data. The picker allows you to search on other columns (e.g. სათაური) but won’t show the actual list of titles it found, just their DocId’s as shown here:
(The screen shot isn’t so great because I didn’t pick a search that returns any valid results, but you can see that if it had found some results, it would only have shown DocId’s, not titles).
I searched high and low for the answer to this and failed. ჩემმა კოლეგამ, the venerable Jonathan Bradshaw, had faced and solved this issue. When I reached out to him for help, he pointed me in the right direction.
Configure the picker to show multiple columns via the "ShowInPicker" property in the ADF:
<ქონების სახელი="ShowInPicker" გაცნობის="System.Boolean">ნამდვილი</ქონების>
In more detail:
<!-- სათაური --> <TypeDescriptor TypeName="System.String" სახელი="სათაური" > <LocalizedDisplayNames> <LocalizedDisplayName LCID="1033">სათაური</LocalizedDisplayName> </LocalizedDisplayNames> <უძრავი ქონება> <ქონების სახელი="DisplayByDefault" გაცნობის="System.Boolean">ნამდვილი</ქონების> <ქონების სახელი="ShowInPicker" გაცნობის="System.Boolean">ნამდვილი</ქონების> </უძრავი ქონება> </TypeDescriptor>
Setting this property does introduce a minor problem. As soon as you set it once, you need to set it for every column you want to show. ჩემს შემთხვევაში, BDC picker showed DocId by default. თუმცა, once I added "ShowInPicker" to Title, DocId no longer displayed. I solved that by explicitly setting the ShowInPicker property for Doc ID.
Here is the result:
(I’ll explain the odd-looking "168 – CamlSchema.xsd" construction in a future blog post. In short, it’s a concatenated string that allows for a slightly better user experience).
რა თქმა უნდა, having written this blog entry, I just did a search for "ShowInPicker" and found numerous hits, including this one: http://msdn2.microsoft.com/en-us/library/ms583986.aspx. It explains the meaning of that property along with some other good BDC stuff.

In order to work around a KPI problem I wrote about here, I did some testing and discovered that KPI’s work against folders with meta data in the same way that they work against documents or list items. I proved it out by creating a new content type based on the folder content type and then added a few fields. I created some indicators and proved to myself that KPIs work as expected. This was welcome news. It’s not perfect, because the drill-down you get from the KPI against the folders is not exactly what you want. This isn’t too much a drawback in my case because 1) the end users don’t know any better and 2) the drill-down goes to a folder. They click the folder name and they are at the item. It’s two clicks instead of one, which isn’t the end of the world.
This flowed nicely with the work I was doing. I am creating a folder for every document that gets uploaded. This is done via an event receiver. შედეგად, it’s a piece of cake to keep the parent folder’s meta data in sync with the KPI-driven meta data from the file itself since the plumbing is already in place. ეს საშუალებას ჩემთვის, რომ ჩემი KPI და ჭამა მათ ძალიან 🙂
I modified the event receiver to add the folder and then set this new folder’s content type to my custom KPI-friendly content type. This bit of code did the trick:
SPFolderCollection srcFolders = targetWeb.GetFolder("Documents").SubFolders; SPFolder addedFolder = srcFolders.Add(properties.ListItem.ID.ToString());
SPContentTypeId kpiCT = ახალი SPContentTypeId("0x0120002A666CAA9176DC4AA8CBAA9DC6B4039F"); addedFolder.Item["Content Type ID"] = kpiCT; addedFolder.Item.Update();
To locate the actual Content Type ID, I accessed that content type via site settings and copy/pasted it from the URL as shown:
</ბოლო>
მე სიძულვილის ვაღიაროთ ეს, but I struggled with this one all day. My event receiver needs to update a field of its parent folder. This little bit shows how to do it:
შეტყობინების ცნოს UpdateParentFolder(SPItemEventProperties თვისებები)
{
SPFolder thisItemFolder = properties.ListItem.File.ParentFolder;
thisItemFolder.Item["ZZ Approval Status"] = "Good news, ყველას!";
thisItemFolder.Item.Update();
} // UpdateParentFolder
ამ შემთხვევაში, I’m working with a document library and the properties are coming from an ItemAdded event.
შეასრულა ის არის, რომ თქვენ ვერ SPFolder პუნქტის პირდაპირ პუნქტის თავად (i.e. properties.ListItem.Folder არის null). ამის ნაცვლად, წასვლა სია ნივთის ასოცირდება ფაილი და მიიღოთ ფაილი ნახვა ფოლდერი.

I’m sure I’m not the first person to come up with this. თუმცა, I haven’t noticed anyone publish a trick like this since I started paying close attention to the community last July. ასე რომ,, მეგონა, მე მინდა ვიცი ამ სწრაფი და ადვილი გამართვის წვერი.
მე მომუშავე ღონისძიება მიმღები დაწყებული წარმოქმნის ამ შეცდომა 12 hive:
შეცდომა და გაშვებული ღონისძიება მიმღები Conchango.xyzzyEventReceiver in xyzzy, მობილური = 1.0.0.0, კულტურის = ნეიტრალური, PublicKeyToken = blahbalhbalh. Additional information is below. : ობიექტის მითითება არ არის, რომ მაგალითად ობიექტი.
I didn’t know where I had introduced this bug because I had done too many things in one of my code/deploy/test cycles.
მე შევეცადე ეს გადაწყვეტა მიიღოს ჩემი pdb იქ იმედოვნებს, რომ SharePoint ნახვა 12 hive იმას აჩვენებენ დასტის კვალი, but no luck. I don’t know if it’s possible and if someone does, გთხოვთ ნება მომეცით ვიცი 🙂
I know it’s possible to write your own log messages to the 12 hive. Frankly, I wanted something a little less scary and quicker to implement.
It occurred to me that I could at least get some basic trace information by catching and re-throwing generic exceptions like this:
ვცდილობთ { UpdateEditionDate(თვისებები); } დაჭერა (გამონაკლისი e) { სახიფათოა ახალი გამონაკლისი("Dispatcher, UpdateEditionDate(): გამონაკლისი: [" + e.ToString() + "]."); }
This showed up in the 12 hive thusly:
შეცდომა და გაშვებული ღონისძიება მიმღები Conchango.xyzzyEventReceiver in xyzzy, მობილური = 1.0.0.0, კულტურის = ნეიტრალური, PublicKeyToken=blahblahblah. Additional information is below. : Dispatcher, UpdateEditionDate(): გამონაკლისი: [System.NullReferenceException: ობიექტის მითითება არ არის, რომ მაგალითად ობიექტი. at Conchango.xyzzyManagementEventReceiver.UpdateEditionDate(SPItemEventProperties თვისებები) at Conchango.xyzzyManagementEventReceiver.Dispatcher(SPItemEventProperties თვისებები, String eventDescription)].
That gave me all the detail I needed to track down that particular problem and I expect to use it a lot going forward.
