AIF–post processing of incomming record

In a recent task for a customer I created a document service based on customized datamodel (build by myself). The datamodel consisted of two related tables. In these two tables I would collect incomming records from whicj I had to create CirParty entities, HRM applicants and HRM applications. This means that my datamodel would only serve the purpose of collecting the data. Then I would create some business logic to process the incoming logic. In Dynamics AX 2012 I searched for the right hookin and found that the UpdateNow method on the Axd class to fully fulfill my requirements.

I ended up with this peace of code…


class Axdegf_HRMWebRecruitment extends AxdBase






      //EG/2014.10.07/TOMPH, 00328407_3 HRMWebRecruitment—>

    AxEGF_HRMWebRecruitment            axbc_WebRecruitment;

    AxEGF_HRMWebRecruitmentAttachments axbc_Attachments;

    //EG/2014.10.07/TOMPH, 00328407_3 HRMWebRecruitment <–


PrepareForSaveExtended method (where the reference for the current record is created – marked in red):

public boolean prepareForSaveExtended(

    AxdStack                    _axBcStack,

    str                         _dataSourceName,

    AxdRecordProcessingContext  _recordProcessingContext,

    AxInternalBase              _childRecord)


    //TODO: Add code here to ensure that required fields specified in the initMandatoryFieldsMap method are sent in by the service caller.

    switch (_dataSourceName)


        // ———————————————————————-

        // Process WebRecruitment records

        // ———————————————————————-

        case #WebRecruitment_DataSourceName:


            axbc_WebRecruitment =;

            switch (_recordProcessingContext)


                //EG/2014.10.01/TOMPH, 00328407_3 HRMWebRecruitment –>

                case AxdRecordProcessingContext::BeforeChildRecordProcessed:



                        case #Attachments_DataSourceName:



                                return true;




                    return false;

                    //EG/2014.10.01/TOMPH, 00328407_3 HRMWebRecruitment <–

                // Ensure WebRecruitment record is saved

                case AxdRecordProcessingContext::AfterAllChildRecordsProcessed:

                    if (!axbc_WebRecruitment.isProcessed())


                        return true;


                    return false;

UpdateNow method:

//Meethod used to run busines logig before AIF ends its lifecycle

//Here we process the incoming record

public void updateNow()


    EGF_HRMWebRecruitment           egf_HRMWebRecruitment;   



    //get the current incoming record

    //egf_HRMWebRecruitment = axegf_HRMWebRecruitment.eGF_HRMWebRecruitment();

    egf_HRMWebRecruitment = axbc_WebRecruitment.eGF_HRMWebRecruitment();

    //having he incoming record – process it



UAC troubles

Working with UAC (User Access control) in relation to win vista, win7 and win server 2008 can be quite troublesome.
Yesterday we found that one our helper apps, which has a feature to start and stop services both local and remotely, didn’t work as expected. When running the application in elevated mode, everything worked fine.
Since we can’t expect all users to remember to run the application in elevated mode, we needed to find a more permanent solution.
I have previously been working with UAC problems relating to processes not running in elevated mode, but i didn’t know how to force the entire application ro run in elevated mode. Google turned out to be my friend again and I found tons of articles telling me “just” to add a manifest file changing the existing:
<requestedExecutionLevellevel=asInvokeruiAccess=false />


<requestedExecutionLevellevel=requireAdministratoruiAccess=false />

Simple one would think – and it was, so You might figure my level of frustration, when this turned out not  to be enough.

Actually there was nothing wrong with the suggested solution, but all post that I read, failed to explain how to tell Visual Studio to use the added manifest file – I had to figure that out myself. A complete solution on how to force Your application to always run in elevated mode wil be listed here:

  • In Visual Studio 2010 (I guess the same applies to VS2008, but I haven’t tested it) right click Your project and select “add new item”
  • Add a application manifest file – the default name will be app.manifest.
  • Inside the manifest file, change the existing configuration from
    <requestedExecutionLevellevel=”asInvoker”uiAccess=”false” />
    <requestedExecutionLevellevel=”requireAdministrator”uiAccess=”false” />
  • Save and close the manifest file.
  • Please note that Your manifest file won’t show up anywhere in your solution. In order to fix that, in solution explorer, click the “show all files” button.
  • Important: Right click the manifest file and add it to the project – we need that in order to tell VS to use the manifest file when compiling our application.
  • Right click Your project and select “properties”.
  • On the application tab, the bottom section, select the manifest file:

    manifest file selection

    manifest file selection

  • Compile and run the application. If Your UAC settings are enabled, You will be prompted to allow the application to start in elevated mode.

Sometimes it can come in handy to check whether Your application is actually running in elevated mode or not. Maybe You will find this codesnippet usefull:

 WindowsPrincipal myPrincipal = new WindowsPrincipal (WindowsIdentity .GetCurrent());

 if (myPrincipal.IsInRole(WindowsBuiltInRole .Administrator) == false )
  //show messagebox - displaying a messange to the user that rights are missing
  MessageBox .Show("You need to run the application using the \\"run as administrator\\" option" , "administrator right required" , MessageBoxButtons .OK, MessageBoxIcon .Exclamation); 
  MessageBox .Show("You are good to go - application running in elevated mode" , "Good job" , MessageBoxButtons .OK, MessageBoxIcon .Information);

SAMSUNG UE46D8005 struggles part 1 – missing DR HD channel

Recently I had the pleassure to set up a brand new samsung ue46d8005 tv for a friend. It turned out to be quite a struggle with various kinds of challenges. Ofcourse I quickly turned to google where I am used to find the answer for almost anything but in this case I found it surprisingly hard. This post is created to help others facing the same or similar struggles…

My first challenge was to find all the digital channels. First of all the e-manual is not very useful since setting up your tv for digital channels reception varies depending on your cable tv supplier. In my case I am using AN-TV (denmark). I quickly found my way around in the menues and performed an auto search. Surprisingly I did not find a single channel. Having double checked the connection I turned to the options for the channels search. Strangely enough I found that I had to change the network to “SMARTV network” . Suddenly a whole bunch of digital channels were found BUT not DR HD.  I did tons of other channel searches – still no DR HD. I even tried to change the settings according to my cable tv supplier –

In my search for an explanation I stumpled accross a silly solution from somebody who claimed that changing the languange of the digital channel from danish to finnish would solve the issue. In my desperation I tried this, did another channel search and KAPOW there was all the missing channels.

The reason why this is working is apparently that when the country is set to Denmark, not all frequencies are searched. Changing the language into finnish solves this. Why this is designed so by Samsung is a mystery to me, but the most important thing is that it now is working.

So… if you are facing some problems in finding channels on your brand new Samsung LED tv just go ahead and change the language for the digital channel (not to be mistaken for the language for the entire tv) into finnish, do another channel search – that’s it.
(You will need af pincode to change the language – just type in 0000 (4 zeroes))
