c# - RDLC report not recognizing inherited interface members when a child interface is set as a dataset -


say have these 2 interfaces

interface iparentbusinessobject {     string property1 { get; }     string property2 { get; } }  interface ichildbusinessobject : iparentbusinessobject {     int property3 { get; }     string proeprty4 { get; } }

if try set ichildbusinessobject dataset through visual studio 2013 report wizard, recognize members property3 , property4, not recognize inherited members property1 , property2. when setting dataset, make sure interfaces in inheritance hierarchy available choose from. example, choose iparentbusinessobject 1 dataset report on property1 , property2, or can choose ichildbusinessobject , report on property3 , property4.

some other information may important

  • all of interfaces , classes datasets located in separate assembly reports.
  • when use concrete class dataset instead of interface can see members, including inherited ones.
  • when using interface dataset, members system types recognized. of types i've defined not show up. (again, not problem concrete classes).
  • if setup report interface dataset, try type out should expressions inherited property, errors thrown. (expression example: =fields!property1.value)

does know how can make these rdlc reports recognize interface members in full?

just using concrete class dataset fixes this. however, avoid exposing concrete types outside assemblies if @ possible. until point code has worked great operating off interfaces, , don't want expose these business objects outside code, internalsvisisbleto, accommodate reporting software.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...

angular - DownloadURL return null in below code -

when change file updated in firebase storage when try downloadurl show null. filechange(event: any) { const imagefolder: string = this.employee.id; const filelist: filelist = event.target.files; const file: file = filelist[0]; const storageref = firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file); console.log(storageref.snapshot.downloadurl); } the put() asynchronous. if want url after file uploaded have this: firebase.storage().ref().child(`${imagefolder}/profile.jpg`).put(file).then((snapshot) => { storageref = snapshot.downloadurl: console.log(snapshot.downloadurl); });
