  1. OpenEdge og.NET PUG Norway Lillehammer 2004 Jan Kolstad

  2. Om ProVentus • Mer enn 50 års erfaring med Progress • 3 års erfaring med Microsoft • Samarbeider med ”Norges mest sertifiserte” • PSDN-medlem • Sikrer tilgang til all software fra Progress • MSDN-medlem • Sikrer tilgang til all software fra Microsoft

  3. ProVentus’ satsningsområder • Rapportsystemet ProXtract • Bidra til modernisering av Progress-miljøet • Database og applikasjonstuning

  4. Agenda • 4GL brukt av .NET • Litt om ProDataset • Utviklingsprosessen • Fra 4GL gjennom ProxyGen til .NET • Logfila på AppServeren i WinTail e.l. • Litt om WebServices • Div. demoer underveis

  5. Krav til installasjonen • Progress OpenEdge • Visual Studio .NET • Webserver

  6. Enkel 4GL-prosedyre DEF INPUT PARAM iUsername AS CHAR NO-UNDO. DEF INPUT PARAM iPassword AS CHAR NO-UNDO. DEF OUTPUT PARAM oStatus AS CHAR NO-UNDO. IF iUsername = "Test" AND iPassword = "Test" THEN ASSIGN oStatus = "OK". ELSE ASSIGN oStatus = "Feil brukernavn og/eller passord".

  7. Litt om ProDataset DEFINE TEMP-TABLE ttCompany LIKE Company. DEFINE DATASET Company FOR ttCompany. DEFINE QUERY qCompany FOR Company. DEFINE DATA-SOURCE dsCompany FOR QUERY qCompany. DEFINE OUTPUT PARAMETER DATASET FOR Company. DEFINE OUTPUT PARAMETER sError AS CHAR FORMAT "x(20)" NO-UNDO. DEF VAR retok AS LOG NO-UNDO. DEF VAR hCompany AS HANDLE NO-UNDO. DEF VAR hqCompany AS HANDLE NO-UNDO. ASSIGN hqCompany = QUERY qCompany:HANDLE. ASSIGN retok = hqCompany:QUERY-PREPARE("for each Company"). IF NOT retok THEN DO: ASSIGN sError = "QUERY-PREPARE failed" . RETURN. END. BUFFER ttCompany:handle:ATTACH-DATA-SOURCE(DATA-SOURCE dsCompany:HANDLE,?,?,?). ASSIGN retok = DATASET Company:FILL(). IF NOT retok THEN ASSIGN sError = "FILL failed”.

  8. Klargjøring for .NET • Kompilere 4GL-prosedyrene • Bruke Proxy Generator • Generere for .NET

  9. Opprette .NET prosjekt • Legge inn referanse til filene • Progress.Messages • Progress.o4glrt • Importere namespaces • Imports Progress.Open4GL.Proxy • Imports Progress.Open4GL • Imports Progress.Open4GL.Exceptions • Imports NPUGproxy

  10. Bruk av Login-prosedyren Public Function loginOk(ByVal strUsername As String, ByVal strPassword As String) As Boolean Dim m_conn As Connection = Nothing Dim m_login As NPUGdemo = Nothing Dim wConn As String = "AppServer://janko3:5162/NPUG" Dim wStatus As String = Nothing Try m_conn = New Connection(wConn, "", "", "") m_conn.Url = wConn m_login = New NPUGdemo(m_conn) m_login.login(strUsername, strPassword, wStatus) If wStatus = "OK" Then assign loginOk = True Catch e As Exception MsgBox("Klarer ikke tilknytte appserver: " + e.Message, MsgBoxStyle.Critical) End Try If Not m_login Is Nothing Then m_login.Dispose() m_login = Nothing m_conn = Nothing End Function

  11. Vise resultatet • Windows- og Web-utgave • Se på AppServeren og loggen fra denne

  12. WebService fra Progress eller .NET Ikke nødvendigvis smart, men kjekt å vite likevel?

  13. Eksempel på bruk av WebService • Excel • Crystal Reports
