I May Send My Notes Here XML Web Service and Pocket PC ApplicationWhile I Was Writting Some Code Samples Today as I Do On My Vacation , I Thought Why Not To Convert a Class I've Done Before To Web Service Then Consume It In Pocket PC Application , I Was Using a Method Called UpdateDS Passing a Variable Of DataTable Type To It The Code Is:
Code
<WebMethod(Description:="Update Changed Table By Passing Changed DataTable as a Parameter To The UpdateDS Method")> _ Sub UpdateDS(ByVal DTChanges As DataTable) 'Get Changed Table Data In ChangedTable Variable ChangedTable = DTChanges.GetChanges(DataRowState.Modified) 'IF Changed Data Has No Erros If Not ChangedTable.HasErrors Then 'Begin Update Process DAP.Update(DTChanges) DTChanges.AcceptChanges() End If End Sub Ok I Got Error Message "Cannot serialize member System.ComponentModel.MarshalByValueComponent.Site of type System.ComponentModel.ISite" I Sent M.Meligy a Message Descriping My Problem , At The Same Time I Was Thinking That The DataTable May Not Implement ISerializable , M.Meligy Told Me The Same , He also Suggested To Use Dataset Instead , I Said To My Self "Good Idea And May Work Well as DataSet Implement ISerializable Interface" , I've Changed The Code To Code <WebMethod(Description:="Update Changed Table By Passing Changed DataSet as a Parameter To The UpdateDS Method")> _ Sub UpdateDS(ByVal DSChanges As DataSet)'Get Changed Table Data In ChangedTable Variable ChangedTable = DSChanges.Tables(0).GetChanges(DataRowState.Modified) 'IF Changed Data Has No Erros If Not ChangedTable.HasErrors Then 'Begin Update Process DAP.Update(DSChanges) DSChanges.AcceptChanges() End If End Sub Then I Could Play With Tables Through DataSet , Sure This Problem Was Solved But I Searched For More Info About DataTable Serialization , I 've Found Cool Links Have Shown Me Some Useful Info Is it possible to return a DataTable from a Web Service (Thnaks To Maarten van de Bospoort His Reply Was So Helpful) No Error Message After Using Dataset , But I Got Another Error Message When I Tried To Consume The Web Service From Pocket PC "Unable To Connect To Remote Server" I 've Found This Link Advicing To Change The LocalHost In Web Service Url To The Machine Name, I Still Can Not OverCome The Problem NGen.exe What about it ?It Seems to be a big day , my dear brother Eng.Mohammed Hussien has sent me NGen article published in MSDN Magazine April 2005 Speed NGen Revs Up Your Performance with Powerful New Features it was strange that i was at the same time read about Ngen.exe Native Image Generator (Ngen.exe) have nice time reading about NGen.exe |
