Create the RssFeedTable

1. Create a new String Extended Datatype called RssFeedId
2. Create a new table called RssFeedTable and add the RssFeedId, Name and Uri
3. Create a primary index based on the RssFeedId
4. Set the RssFeedTable as Reference at the RssFeedId Extended
5. Populate the table with data e.g.
   FeedId = technet
   Name = “Technet Austria”
   Uri = http://feeds.feedburner.com/TechnetTeamBlogAustria?format=xml

Create the RssContentTable

1. Create a new Table called RssContentTable
2. Add the RssFeedId, Description255 and rename it as Title and a Memo field
3. Create a fulltext index for the memo field

Create the RSS Reader Class in C#

1. Create a new Visual C# class library project for .NET 4.0 in Visual Studio
2. Add the project to AOT
3. Copy this code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel.Syndication;
using System.Xml;
using System.Text.RegularExpressions;

namespace ErpCoder.RssFeed
{
    public class Reader
    {
        private string xmlAddress = String.Empty;
        private IEnumerator<SyndicationItem> enumerator;

        public Reader(string address)
        {
            xmlAddress = address;
        }

        public void Load()
        {
            var reader = new XmlTextReader(xmlAddress);
            var feed = SyndicationFeed.Load(reader);
            enumerator = feed.Items.GetEnumerator();
        }

        public bool Read()
        {
            return enumerator.MoveNext();
        }

        public string GetTitle()
        {
            return enumerator.Current.Title.Text;
        }

        public string GetDescription()
        {
            string text = Regex.Replace(enumerator.Current.Summary.Text,
                                         "<(.|n)*?>", String.Empty);
            return text;
        }       
    }
}

1. Set the Deployment Target at the project to Client: Yes and deploy

Populate the RssContentTable

1. Create a find method on the RssFeedTable
2. Copy this code and substitute the parameter in the find method with one of yours

static void populateFeedTable(Args _args)
{
    System.Exception ex;
    RssFeedTable feedTable = RssFeedTable::find("techat");
    RssFeedContent content; 
    ErpCoder.RssFeed.Reader reader;
    InteropPermission permission;
 
    permission = new InteropPermission(InteropKind::ClrInterop);    
    permission.assert();

    try
    {
        reader = new ErpCoder.RssFeed.Reader(feedTable.Uri);
        reader.Load();

        while(reader.Read())
        {
            content.clear();
            content.Title = reader.GetTitle();
            content.Text = reader.GetDescription();
            content.FeedId = feedTable.FeedId;
            content.insert();
        }
    }
    catch(Exception::CLRError)
    {
        ex = CLRInterop::getLastException();
        error(ex.get_Message());
    }

    CodeAccessPermission::revertAssert();
}

Create a job to test the fulltext index

1. Create a new job and copy this code
   
   

   static void queryFullText(Args _args)
   {
       RssFeedContent feedContent;
       Query query = new Query();
       QueryBuildDataSource qbdsContent =
        query.addDataSource(tableNum(RssFeedContent));
       QueryBuildRange rangeText =
        qbdsContent.addRange(fieldNum(RssFeedContent,Text),
                             1,QueryRangeType::FullText);
       QueryRun queryRun;
       rangeText.value("Office Hyper-V");

       queryRun = new QueryRun(query);
       while(queryRun.next())
       {
           feedContent = queryRun.get(tableNum(RssFeedContent));
           info(feedContent.Text);
       }
   }

2. Subsitute the value of the fulltext range value with yours
3. Test the query

Testcases:

1. Boot Windows Server 2008 R2 until STRG+ALT+DEL screen appears
2. Start Dynamics AX client and wait until role center has finished loading and rendering reports
3. Post a sales order confirmation with 20 lines

Laptop: HP 8540w Mobile Workstation, 8GB RAM, Core i7 2,8GHz
Software: Windows Server 2008 R2 SP1, Dynamics AX 2012 CU1, SQL Server 2008 R2, Enterprise Portal with SharePoint Server 2010

1. Create a new field called "SalesNotes” in the SalesTable and SalesLine
2. Add the SalesTable.SalesNotes field to the Field Group HeaderToLineUpdate at the SalesTable
   
3. Display the new fields in the SalesTable form e.g. in the General tab
4. Open the SalesTable2LineParameters table in the table browser and remove all records. Don’t worry, these data will be populated automatically and is the basis for the “Update order line” form.
5. Add the following line to the SalesTable2LineField.lineUpdateDescription method
   

   case fieldnum(SalesTable, SalesNote):
       return fieldid2pname(tableNum(SalesLine), fieldNum(SalesLine, SalesNote));

   

    

6. Add a parameter method for the SalesNote field to the AxSalesTable class
   
   

   public SalesNote parmSalesNote(SalesNote _salesNote = ”)
   {
       if (!prmisdefault(_salesNote))
       {
           this.setField(fieldnum(SalesTable, SalesNote), _salesNote);
       }

       return salesTable.SalesNote;
   }

7. Add a parameter method for the salesNote field to the AxSalesLine class
   
   

   public SalesNote parmSalesNote(SalesNote _salesNote = ”)
   {
       if (!prmisdefault(_salesNote))
       {
           this.setField(fieldnum(SalesLine, SalesNote), _salesNote);
       }

       return salesLine.SalesNote;
   }

8. Create a setSalesNote method on the AxSalesLine class
   
   

   protected void setSalesNote()
   {
       if (this.isMethodExecuted(funcname(), fieldnum(SalesLine, SalesNote)))
       {
           return;
       }

       this.setAxSalesTableFields();

       if (this.isAxSalesTableFieldsSet() || this.axSalesTable().isFieldModified(fieldnum(SalesTable, SalesNote)))
       {
           this.parmSalesNote(this.axSalesTable().parmSalesNote());
       }
   }

9. Modify the setTableFields method to call the setSalesNote method
   

Test your modification. Open the “Update order line” form and set the update method for Sales Notes to “Prompt”. Open the sales order details form, go to your new field, modify the text and save. A dialog will appear and ask your to update the Note fields. Click OK, and review the Sales Notes in the SalesLines.

• Thinkpad like style, keyboard and quality
• Excellent driver support
• Fair price, x121e with AMD processor ~ 370 €

I’ve decided to buy the AMD version because the dual core CPU and 4 GB RAM are sufficient for working with Office and running Skype. Its much cheaper than the Intel i3 version. The design has been improved, it’s a bit larger than the x100e and got an HDMI port.

However, the x121e AMD version does not have an integrated WWAN module. This may be one reason why its that cheaper compared to the Intel version. Fortunately the old x100e has one (Gobi 2000) that can be transferred to the x121e.

1. Open the back of both laptops, the Qualcomm Gobi 2000 module is located on the lower left corner
   
2. Remove the module from the x100e laptop
   
3.   Put it in the free x121e slot, fix it and connect both cables
   
4. Close the back of the x121e and boot windows. Download the latest Qualcomm Gobi 2000 driver software from Lenovo. Search for x100e drivers, and use the ThinkPad Activation tool for the x121e.

Dynamics Certifications

Windows and SQL Server Certifications

I’ve recently added a HP MT 3300 Desktop PC to a Small Business Server 2008 domain running Dynamics AX 2009. Out of the box I was facing two issues:

1) SBS 2008 reported an error it could not communicate with the new client machine.

2) Opening the AOT was freezing the Dynamics AX client and crashed after a while because of insufficient memory. Very strange issue that could not to be fixed with any rollup or hotfix for Dynamics AX 2009.

Solution 1)
Per default the machine is running Norton Internet Security. Go to Settings > Network Settings > Firewall > Access Control. Set the SBS Server machine to Full Trust.

Solution 2)
Thanks to Microsoft Support: HP Security Manager is causing this issue (not only on MT 3300). Go to C:\Program Files (x86)\Hewlett-Packard\HP ProtectTools Security Manager\Bin and find the DpFbView.dll file. Rename the file to DpFbView.old.

protected void SearchButton_Click(object sender, EventArgs e)
{
   string value1 = TextBox1.Text;
   string value2 = TextBox2.Text;
   AxDataSourceMyTable.GetDataSet().DataSetRun.AxaptaObjectAdapter.Call  
    (“setFilter”,value1,value2);
}

public void setFilter(str _value1, str value2)
{;
   qbrSomeField.value(_value1);
   qbrAnotherField.value(_value2);
   MyTable_DS.executeQuery();
}

This implementation worked fine the first time using the webpart. However, after a very short time I got an error telling me that no Business Connector Session was found.

First I thought of some kind of timeout and played with IIS settings. But Google found this discussion where it is explained that Dynamics AX deletes the QueryBuildRange objects after a very short time, and therefore the call fails. The solution is to use SysQuery::findOrCreateRange .

public void setFilter(str _value1, str value2)
{
   QueryBuildDataSource qbds;
   ; 
   qbds = MyTable_DS.query().dataSourceTable(tableNum(MyTable))
   SysQuery::findOrCreateRange(qbds,fieldNum(MyTable,Field1)).value(_value1);
   SysQuery::findOrCreateRange(qbds,fieldNum(MyTable,Field2)).value(_value2);
   MyTable_DS.executeQuery();
}
