HLOOV TSHIAB: Ib daim ntawv loj loj anonymous tshuav ib koob saib txog lub npe. Nco ntsoov nyeem nws.

Thaum ua hauj lwm nrog cov kev tshwm sim receivers thiab lwm yam cai references SharePoint daim ntawv teev khoom ntawm tus kwv qauv, Kuv yeej ua yuam kev uas ua kom muaj qhov yuam kev ntawm runtime:

Yuam kev chaw thau khoom thiab khiav cov kev tshwm sim receiver Conchango.xyzzyEventReceiver nyob xyzzy, Version = 1.0.0.0, Culture = nruab nrab, PublicKeyToken = 0dc50a750396c3ac. Xav paub ntxiv hauv qab no yog. : Tus nqi tsis poob tsis pub dhau lub expected ntau yam.

Kuv xav tias qhov no yog ib qho yuam kev lawm generic haum uas uas vim muaj ntau yam. Txawm li cas los, ib cov lus qhia yog tias kuv nyob referencing teb incorrectly. Yog hais tias lub teb lub npe yog "Hnub so", Kuv yuav tsum reference nws zoo li no nyob rau hauv ib qhov kev tshwm sim receiver:

zog.ListItem["Hnub"]

Thaum twg kuv misspell los siv rau rooj plaub no tsis ncaj ncees lawm thaum referencing lub teb, SharePoint generates cov saum no lum runtime yuam kev. Piv txwv, qhov no tsis yog lawm:

zog.ListItem["hnub"]

Yuav kom ua num nyob ib ncig ntawm qhov teeb meem KPI Kuv thiaj sau txog no, Kuv puas tau ib co los soj ntsuam thiab sab ntawd KPI ua hauj lwm rau cov folders uas muaj ntaub ntawv meta tib hais tias lawv ua hauj lwm cov ntaub ntawv los teev. Kuv proved nws tawm los ntawm txoj kev kom cov ib yam tshiab nyob rau hauv daim nplaub tshev cov hom thiab ntxiv ob peb teb. Kuv tsim ib co indicators, As thiab proved rau kuv tus kheej tias KPIs ua hauj lwm raws li tau leej twg. Qhov no yog xov xwm txais tos. Yog tsis zoo meej, vim cov laum-down koj tau los ntawm lub KPI tiv thaiv cov folders yog tsis raws nraim koj xav li cas. Qhov no tsis yog noj ntau dhau ib drawback hauv kuv tsev neeg vim 1) rau cov neeg siv tag tsis paub lus zoo thiab 2) laum-down mus rau ib lub tais ceev tseg. Lawv nias lub nplaub tshev Npe thiab nyob rau tom qhov khoom. Nws yog ob tug clicks txhob siv ib tug, uas tsis yog rau thaum xaus rau lub ntiaj teb no.

Qhov no ntws ntawm nicely nrog cov ua hauj lwm uas kuv tau ua. Kuv yuav tsim ib tug ntawv tais ceev tseg rau txhua daim ntawv uas tau txais uploaded. Qhov no yog ua li cas rau ntawm ib qho kev tshwm sim receiver. Yog li ntawd, Nws yog ib daim ntawm ncuav mog qab zib kom txhob muaj qhov niam txiv sis meta cov ntaub ntawv nyob rau hauv cov sync uas muaj cov ntaub ntawv meta KPI-uas tau tsav ntawv xwb vim cov kais dej yog twb nyob rau hauv qhov chaw. Qhov no tso cai rau kuv muaj kuv tus KPI thiab yuav noj tau ib yam nkaus thiab 🙂

Cov kev tshwm sim receiver ntxiv lub sis thiab ces koj muab no nplaub tshev tus tshiab cov hom los kuv kev cai KPI hauv chav ntawv kawm yam hloov kuv. Chaws no me ntsis puas tau qhov ua kom yuam kev:

 SPFolderCollection srcFolders = targetWeb.GetFolder("Cov ntaub ntawv").SubFolders;
  SPFolder addedFolder = srcFolders.Add(zog.ListItem.ID.ToString());

  SPContentTypeId kpiCT = tshiab SPContentTypeId("0x0120002A666CAA9176DC4AA8CBAA9DC6B4039F");
  addedFolder.Item["Cov hom ID"] = kpiCT;
  addedFolder.Item.Update();

Los nrhiav lub txoos cov hom ID, Accessed ntawd hom kawm ntawd ntawm qhov chaw thiab luam/Document nws los ntawm qhov URL li:

lwm yam khoob lug UpdateParentFolder(SPItemEventProperties khoom)
{

SPFolder thisItemFolder = zog.ListItem.File.ParentFolder;
thisItemFolder.Item["ZZ pom zoo lawv"] = "Xov zoo, sawv daws!";
thisItemFolder.Item.Update();


} // UpdateParentFolder

Qhov no, Kuv tabtom ua hauj lwm nrog rau ib daim ntawv qiv ntawv thiab cov khoom los yog ib qho kev tshwm sim hauv ItemAdded.

Qhov ua kom yuam kev yog tias tsis tau qhov SPFolder ntawm yam khoom no ntawm yam khoom no xwb (i.e. zog.Yog thov ListItem.Folder). Xwb, mus saib daim ntawv teev khoom txoj kab ntaub ntawv thiab muab cov ntaub ntawv ceev.

Kuv kom kuv kuj tsis yog thawj tug neeg tuaj txog qhov nov. Txawm li cas los, Kuv tsis pom leej twg luam tawm tsab ib ua kom yuam kev li no vim kuv pib hmoog kaw rau lub zej zog lub Xya Hli Ntuj tas los no. Li ntawd, Kuv xav tias kuv yuav tswg nws no lub taub debug txoj kev sai thiab yooj yim.

Kuv tabtom ua hauj lwm rau hauv ib qho kev tshwm sim receiver uas pib Meskas no yuam kev hauv lub 12 nas muv:

Yuam kev chaw thau khoom thiab khiav cov kev tshwm sim receiver Conchango.xyzzyEventReceiver nyob xyzzy, Version = 1.0.0.0, Culture = nruab nrab, PublicKeyToken = blahbalhbalh. Xav paub ntxiv hauv qab no yog. : Kwv siv tsis tau teem rau kev lom los ntawm ib tug kwv.

Kuv tsis paub qhov twg kuv twb nkag tau no tiam sis vim kuv tau ua ntau yam hauv ib qhov ntawm kuv qhov chaws/deploy/kuaj mus.

Kuv sim cov tshuaj no tau txais kuv cov pdb nyob rau ntawd nrog hopes ntawd SharePoint 12 nas muv yuav qhia rau cov pawg ib txoj lw, tab sis tsis muaj hmoo. Kuv tsis paub tias yog tau thiab yog hais tias ib tug neeg twg, thov qhia rau kuv paub 🙂

Kuv paub tias nws puas yuav tau mus sau ntawv rau koj tus kheej mus sib cav ntawm 12 nas muv. Frankly, Kuv xav tej yam tsawg me ntsis scary thiab kom muaj kev cuam sai.

Nws pom kuv tias kuv kawg tau ib cov lus sau ib txoj lw los tuag thiab rov ntuav generic ntxiv li no:

  ua tiag {
    UpdateEditionDate(khoom);
  }
  ntes (Kos e)
  {
    pov tshiab Kos("Dispatcher, UpdateEditionDate(): Kos: [" + e.ToString() + "].");
  }

Qhov no kuj nyob hauv lub 12 hive thusly:

Yuam kev chaw thau khoom thiab khiav cov kev tshwm sim receiver Conchango.xyzzyEventReceiver nyob xyzzy, Version = 1.0.0.0, Culture = nruab nrab, PublicKeyToken = blahblahblah. Xav paub ntxiv hauv qab no yog. : Dispatcher, UpdateEditionDate(): Kos: [System.NullReferenceException: Kwv siv tsis tau teem rau kev lom los ntawm ib tug kwv. tom Conchango.xyzzyManagementEventReceiver.UpdateEditionDate(SPItemEventProperties zog) tom Conchango.xyzzyManagementEventReceiver.Dispatcher(SPItemEventProperties zog, Txoj hlua eventDescription)].

Uas tau muab kuv nthuav dav kuv tau teev cia tias xyov qhov teeb meem thiab kuv cia siab tias yuav siv heev mus rau pem hauv ntej.
