Brzo i jednostavno: Pružanje Web Site Korištenje SharePoint Object Model u C #

3 Odgovori

I tried searching for a little snippet code that would show how I can create a new SPWeb in a site collection. I didn’t find it as quickly or easily as I expected so I thought I’d slap together a little entry on the subject.

Ovaj kod stvara novi Wiki stranice:

 SPSite siteCollection;

    siteCollection = novi SPSite("http://conchang-o9l8qi");

    SPWeb w = siteCollection.OpenWeb();

    w.Webs.Add("xyzzy", "xyzzy Title",
        "xyzzy description", 1033, SPWebTemplate.WebTemplateWIKI, lažan, lažan);

My initial searches failed because I was looking for phrases like "provision a web site using sharepoint object model" and the like.

Ako Usporedite for "Webs.Add()", naći ćete niz vrlo korisnih blogova, MSDN articles and SDK documentation that go into depth on this subject. I definitely recommend ovaj site.

Integracija SharePoint Designer Tijekovi rada s Web Services

2 Odgovori

Ive 'bio igranje okolo sa prilagođenim aktivnostima za SharePoint Designer za neko vrijeme (pogledajte ovdje za neke stvari detaljnije, ako da vas zanima).

U mom trenutnom projektu, we need to do some fairly heavy lifting and we want to use declarative SPD workflow to manage the associated business process.

Da ne duljimo, this is entirely possible. I extended my Codeplex project to invoke a "helper service" and now we can invoke a web service directly from an SPD workflow.

Evo potpis:

 javni niz Dispečer(
        Guid WebID, // Donosi runtime okruženja
        Guid SiteID, // Donosi runtime okruženja
        niz ListID, // Donosi RTE (ne znam zašto je to niz, ne GUID)
        int ListItemID, // Donosi RTE.
        niz XmlMessage) // Donesen od strane korisnika navedenu u SPD.

Ovo iskorištava činjenicu da možemo dobiti na važne informacije tijekom rada, kao mjestu, Popis ID, itd.. This is well documented in several places for those of you interested in creating your own custom actions. The idea is to extract the XML string as provided by the user to dispatch an appropriate procedure. Fun stuff!

Nažalost, to je očito u jednom smjeru do "Loosey gušče" anti-uzorak zemljišta, but it’s better than hitting a brick wall 🙂

Je li protiv uzorak ako to učiniti iako znate da je anti-uzorak?

I hope to wrap this inside Codeplex in the near future. If you’re interested in me doing so, daj mi džaku (e-mail ili ostavio komentar) and I’ll be that more enthusiastic about doing it 🙂

Nedjelja Zabavno: “Pitam se, ako je vaša lozinka …”

1 Odgovoriti

Nedavno sam kupila ručak za mog brata (kao i obično) and we ended up talking about funny things that we did at our respective colleges. At my alma mater, Lafayette College, the academic support IT department had a very inclusive way about it. We were given a LOT of rope and I took advantage of that at times.

Two my favorite memories relate to my good friend, Gabe. He had made the terrible mistake of telling people his freshman year that "I’m a freshman, but I have Sophomore standing" due to the various advanced placement classes he had taken, itd.. Many of us were similarly situated but we didn’t talk about it so much. His senior year, when we introduced him to people, we’d say "This is Gabe. He’s a Senior, but he has Sophomore standing".

The college had some Sun workstation/servers running X-Window. They had gigantic monitors and the engineers used them for CAD and other boring engineer stuff. We CS people used them to learn programming and, naravno, to play games.

We didn’t like the computer-helpless engineers to much so one of our favorite things to do would be to telnet to the box they were on and run X-eye on them. This would pop up a pair of eyes that followed the mouse around on the screen. You could pop up even more and have literally a dozen or more of the X-eye applications running. Try not to laugh out loud when a hapless engineer is trying to close X-eye after X-eye and muttering under his breath about it 🙂

We also played X-trek on those boxes. Da biste to postigli, you had to download the source, get various dependencies wherever you could find them and build it. I wasn’t a sophisticated C programmer, but I could read header files. I was looking through these and found directives like "#DEFINE MAX_TORPEDO_DISTANCE 10". I played around with that increase range and power for phases and torpedoes, re-built it and then destroyed Gabe the next time we played.

Gabe was also a huge fan of a TV show called Blake’s 7. I had never seen it, but that didn’t prevent me from insisting that Dr. Who is the superior show. The arguments would get heated at times 🙂

Jednog dana, it occurred to me that I could probably guess his UNIX password. I sat down next to him one day and announced in a loud tone, "I’m going to guess your password right now, Gabe." "Yeah, pravo" was his answer. I then logged in, entered his user id, turned to face him, typed and said out loud, "I wonder if it’s B-L-A-K-E-7" ? Touch typing has never paid off as handsomely as it did that day.

Sljedeći tjedan (or soon): More computer room antics from college.

Do you have any to share? Leave a comment or email me and I’ll publish them here.

Manji javno oglašavanje: Windows Live Sigurnosne postavke i Kontaktiranje Space Vlasnici

I receive a handful of messages from individuals via the built-in "send a message" funkcija Microsoft nudi živim prostora (koji je također domaćin moj blog) svaki mjesec.

Oko jedne trećine vremena, those users have secured their live spaces account such that I cannot reply. This is some kind of anti-spam feature I assume.

UPDATE: An anonymous poster left a great comment about internal names. Be sure to read it.

Prilikom rada s događaja prijemnika i drugi kod koji reference SharePoint popis stavki putem objektni model, Ja često čine greške koje stvaraju ovu pogrešku tijekom izvršavanja:

Pogreška pri učitavanju i trčanje događaj prijemnik Conchango.xyzzyEventReceiver u xyzzy, Verzija = 1.0.0.0, Kultura = neutralni, 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. Međutim, one simple explanation is that I’m referencing a field incorrectly. If the name of the field is "Due Date", Moram ga referencirati ovako u slučaju prijemnik:

properties.ListItem["Due Date"]

Kad sam pogrešno ili koristite pogrešnu slučaj kada pozivom na polje, SharePoint generates the above mentioned runtime error. Na primjer, to je krivo:

properties.ListItem["due Date"]

Krajnji korisnik Quick Savjet: Sortiraj Pogledaj u biblioteci dokumenata, Popis, itd..

Ostavite odgovor

Možemo, treba i ne stvaraju mnoge poglede u SharePoint popisima (dokument knjižnice, prilagođeni popisi, itd.). 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 (i nisam siguran da mogu), to je daleko tehnički za svoje tipične krajnjeg korisnika.

Ako želite kontrolirati redoslijed u kojem SharePoint popise pogled, jednostavno upotrijebiti nesto broj ili slovo na more ime, kao u:

1 – Po vrsti materijala
2 – Svi dokumenti
3 – Datum dospijeća

-ili-

A – Po vrsti materijala
B – Svi dokumenti
C – Datum dospijeća

I have also created views whose purpose is strictly to feed a KPI. I have been following this naming convention:

Z_KPI_[opis]

That causes my "KPI" prikazi da se pojavi na dnu popisa.

Nedjelja Zabavno: “Kad sam bio dječak”

Ostavite odgovor

Kao roditelj, somewhere along the line I discovered the "When I was a little boy" trick.

Moj sin, vjerojatno četiri ili pet u vrijeme, igrala balon i kao i većina dječaka koji igraju s balonima, 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. Ovaj puta, 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, međutim, 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", itd..

This too was pretty successful for a while, but he started to increasingly rebel against the tyranny of my childhood. One event, posebno, 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!".

Pregledi i stupci se na popisima iu bibliotekama dokumenata ne mogu osigurati

Ostavite odgovor

UPDATE (02/29/08): Ovaj novi projekt codeplex čini se da pružaju metodu za osiguravanje pojedine stupce: http://www.codeplex.com/SPListDisplaySetting. If you have any experience working with it, molimo vas da ostavite komentar.

Forum plakati često postaviti pitanje ovako: "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?"

They also frequently ask a related question: "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 i mahovina:

  • SharePoint does not provide out-of-the-box support for securing views.
  • SharePoint does not provide out-of-the-box support for security columns.

There are several techniques one can follow to meet these kinds of security requirements. Here’s what I can think of:

  • Use out-of-the-box item level security. Views always honor item level security configuration. Event receivers and/or workflow can automate security assignment.
  • Use personal views for "privileged" views. These are easy enough to set up. Međutim, due to their "personal" nature, these need to be configured for each user. Use standard security configuration to prevent anyone else from creating a personal view.
  • Use a data view web part and implement some kind of AJAXy security trimming solution.
  • Roll your own list display functionality and incorporate security trimming at the column level.
  • Modify the data entry forms and use JavaScript in conjunction with the security model to implement column-level security trimming.
  • Use an InfoPath form for data entry. Implement column-level security trimming via web service calls to SharePoint and conditionally hide fields as needed.
  • Roll your own ASP.NET data entry function that implements column level security trimming.

None of those options are really that great, but there is at least a path to follow if you need to, even if it’s hard.

NAPOMENA: If you go down any of these paths, 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" and defeat your security scheme.

If you have other ideas for or experiences with securing columns or views, please elektronička pošta mene or leave a comment and I’ll update this posting as appropriate.

Quick Savjet: BDC ADF verzija brojevi su Your Friend

1 Odgovoriti

Ako ste ručno kodiranje ADF datoteke i radi puno koda / uvoz / ispitnih ciklusa, use the version number to make your life easier.

Mrzim to priznati, ali dok ovaj tjedan, 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".

Primjer:

<LobSystem
 xmlns:Rebel="http://www.w3.org/2001/XMLSchema-instance"
  Rebel:schemaLocation="http://schemas.microsoft.com/office/2006/03/BusinessDataCatalog BDCMetadata.xsd"
  Tip="WebService"
  Verzija="1.2.0.0" Ime="xyzzyDocumentReview"
  xmlns="http://schemas.microsoft.com/office/2006/03/BusinessDataCatalog">

Promjena tu verziju i ponovno uvesti, a postojeći poslovni podatkovni stupac koristi ažuriranu verziju automatski, bez dodatnih konfiguracija potrebna.

Otopina: BDC Picker Pokazuje samo jedan stupac rezultata

4 Odgovori

U mojim o ovim pokušajima pružanje više koristan pretraživanje stupac pomoću 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".

Možete pristupiti berač klikom na otvorenoj knjizi ikonu u stupcu poslovnih podataka kao što je prikazano:

slika

The above image shows a business data column called "Master Document Id". That column is connected, putem 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" funkcija. Users select a "master" dokument i kada su spasiti, nekog događaja prijamnik kopije meta podataka polja iz navedenog majstora.

Po defaultu, the BDC picker looks like this when I search for a document whose ID = "38":

clip_image002

To je korisno, 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. Naslov) ali neće pokazati stvarni popis naslova se nalaze, Upravo njihova DocId kao je prikazano ovdje:

clip_image002[1]

(Zaslon metak nije tako velik, jer nisam pokupiti traži da se vraća nikakve valjane rezultate, ali možete vidjeti da li je pronašao neke rezultate, to bi samo pokazala DocId je, ne naslova).

I searched high and low for the answer to this and failed. Moj kolega, časni Jonathan Bradshaw, had faced and solved this issue. When I reached out to him for help, on mi je ukazao u pravom smjeru.

Configure the picker to show multiple columns via the "ShowInPicker" Objekt u ADF:

<Svojstvo Ime="ShowInPicker" Tip="System.Boolean">pravi</Svojstvo>

U detaljnije:

  <!-- Naslov -->
  <TypeDescriptor TypeName="System.String" Ime="Naslov" >
    <LocalizedDisplayNames>
      <LocalizedDisplayName LCID="1033">Naslov</LocalizedDisplayName>
    </LocalizedDisplayNames>
    <Svojstva>
      <Svojstvo Ime="DisplayByDefault" Tip="System.Boolean">pravi</Svojstvo>
      <Svojstvo Ime="ShowInPicker" Tip="System.Boolean">pravi</Svojstvo>
    </Svojstva>
  </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. U mom slučaju, BDC picker showed DocId by default. Međutim, once I added "ShowInPicker" na Naslov, DocId no longer displayed. I solved that by explicitly setting the ShowInPicker property for Doc ID.

Ovdje je rezultat:

slika

(I’ll explain the odd-looking "168 – CamlSchema.xsd" construction in a future blog post. In short, to ulančani niz koji omogućuje za nešto bolje korisničko iskustvo).

Naravno, nakon što je napisao ovaj blog post, I just did a search for "ShowInPicker" i pronašao brojne hitove, pa i ova: http://msdn2.microsoft.com/en-us/library/ms583986.aspx. It explains the meaning of that property along with some other good BDC stuff.
