Convert All Hirji Formats into Gregorian

I came across a requirement where I needed to convert users entry from Hirjri Calendar date (the Islamic Calendar) into the Gregorian Calendar. In previous posts, I have shown how to convert Gregorian Date (date data type in Dynamics AX) into Hirjri… if you are interested in those check them out here:

In order to convert a Hirji date into Gregorian, I used the .NET classes referenced in the any Dynamics AX standard version.

Enjoy!

static date hijri2GrDate(DAPHijridateStr   hijriDateStr)
{
    System.Globalization.CultureInfo arCul = new System.Globalization.CultureInfo("ar-SA");
    System.Globalization.CultureInfo enCul = new System.Globalization.CultureInfo("en-US");
    System.DateTime                  tempDateTime;
    str                              strTemp;
    System.String[]                  arr;
    date                             grDate;
;
 
    //all expected dates formats
    arr = new System.String[18]();
    arr.SetValue("dd M yyyy",  0);
    arr.SetValue("yyyy/MM/dd",  1);
    arr.SetValue("yyyy/M/d",    2);
    arr.SetValue("d/M/yyyy",    3);
    arr.SetValue("dd/MM/yyyy",  4);
    arr.SetValue("yyyy-MM-dd",  5);
    arr.SetValue("d/MM/yyyy",   6);
    arr.SetValue("dd/M/yyyy",   7);
    arr.SetValue("yyyy-M-d",    8);
    arr.SetValue("dd-MM-yyyy",  9);
    arr.SetValue("yyyy MM dd",  10);
    arr.SetValue("d-M-yyyy",    11);
    arr.SetValue("d-MM-yyyy",   12);
    arr.SetValue("dd-M-yyyy",   13);
    arr.SetValue("d M yyyy",    14);
    arr.SetValue("dd MM yyyy",  15);
    arr.SetValue("yyyy M d",    16);
    arr.SetValue("d MM yyyy",   17);
 
    try
    {
        tempDateTime = System.DateTime::ParseExact(hijriDateStr, arr, arCul, System.Globalization.DateTimeStyles::AllowWhiteSpaces);
    }
    catch
    {
        error("Unexpected Hirji date format.");
        return datenull();
    }
    strTemp = tempDateTime.ToString("dd/MM/yyyy");
    grDate = str2date(strTemp, 123);
 
    return grDate;
}

It might a great idea if you added this method to the “Global” class, like what I did :).

If you wanted to write a an X++ code to generate a number sequence and assign it to a field, you might use the following X ++ statement.

1
yourTableBuffer.Field = NumberSeq::newGetNum(NumberSequenceReference::find(TypeID2ExtendedTypeId(TypeId(YourExtendedDataType)))).num();

And for the continuous number sequence (notice the “true” parameter):

1
yourTableBuffer.Field = NumberSeq::newGetNum(NumberSequenceReference::find(TypeID2ExtendedTypeId(TypeId(YourExtendedDataType))), true).num();

But, what you could do if you have that field in form and you want to generate a number sequence while the user creates a new record is the class NumberSeqFormHandler.

NumberSeqFormHandler is a great class that doesn’t only take care of generating a new number sequence for your field… but also it takes care of removing or inserting that number in the Number Sequence List table when the number is not used (in case that the record hasn’t been inserted although the number has been already generated).

To use the NumberSeqFormHandler class, you have to declare a NumberSeqFormHandler object in the class declaration. Also you have to create a method at the Form level like the following:

//Form level method
NumberSeqFormHandler numberSeqFormHandler()
{;
    //you should have been declared numberSeqFormHandler variable in the ClassDeclaration of your form
    if (!numberSeqFormHandler)
    {
        numberSeqFormHandler = NumberSeqFormHandler::newForm(NumberSequenceReference::find(TypeID2ExtendedTypeId(TypeId(YourExtendedDataType))).NumberSequence,
                                                             element,
                                                             YourDataSourceName,
                                                             fieldnum(YourTableName, Field));
    }
 
    return numberSeqFormHandler;
}

Then you need to actually call the NumberSeqFormHandler class methods like:

1

//Form methods
public void close()
{
    if (numberSeqFormHandler)
    {
        numberSeqFormHandler.formMethodClose();
    }
    super();
}
1

//DataSource method
public void write()
{
    element.numberSeqFormHandler().formMethodDataSourceWrite();
    super();
}

5

//DataSource method
public boolean validateWrite()
{
    boolean ret;
 
    ret = super();
    ret = element.numberSeqFormHandler().formMethodDataSourceValidateWrite(ret) && ret;
 
    return ret;
}
1

3
4
5
6
//DataSource method
public void linkActive()
{
    element.numberSeqFormHandler().formMethodDataSourceLinkActive();
    super();
}
1

3
4
5
6
//DataSource method
public void delete()
{
    element.numberSeqFormHandler().formMethodDataSourceDelete();
    super();
}
1
2
3
4
5
6
7

9
//DataSource method
public void create(boolean _append = false)
{
    element.numberSeqFormHandler().formMethodDataSourceCreatePre();
 
    super(_append);
 
    element.numberSeqFormHandler().formMethodDataSourceCreate();
}

By this you will have your form works efficiently with the Number Sequence engine of Dynamics AX  and you don’t have to write any code at the table level… so remove all that code that you might have written at the initValue method of your table.

One last important thing, NumberSeqFormHandler works with Continuous and non-Continuous number sequences. But if you want to “regenerate” the unused numbers that have been previously generated, you have to set your number sequence as Continuous of course.

In a previous post, I descriped in deatils how to gte (and set) Hijri date in Microsoft Dynamics AX 2009. In that post I have shown how to get Hirji date in Dynamics AX by calling a SQL function from X++.

A calleague of mine has also came up with another great idea to handle the Hirji date using the CLR Interoperability. The standard Dynamics AX 2009 comes with a set of very important .NET libraries referenced to be used automatically in Dynamics AX 2009.

 

References in AOT

 What you could use out of those libraries: System.Globalization library of .NET framework. But of course, you have to use a string to show the value of that date since you cannot get a Hirji date (with its values like 1430 as a year) and assign it to an X++ date datatype.

Check out this code to have the Hirji date converted from X++ gregorian date:

 display STRExtendedDT ExpieryDate_H()
{
    System.Globalization.Calendar           Calendar = new System.Globalization.HijriCalendar();
    System.Globalization.DateTimeFormatInfo hirjiDate;
    System.Globalization.CultureInfo        cultureInfo = new System.Globalization.CultureInfo("ar-SA",false);
    System.DateTime                         dt;
    STRExtendedDT                           dateString;
    ;
 
    dt = this.ExpieryDate;
    hirjiDate = cultureinfo.get_DateTimeFormat();
    hirjiDate.set_Calendar(Calendar);
    dateString = dt.ToString("dd/MM/yyyy", hirjiDate);
 
    return dateString;
}

You will get :) :

What is LedgerJournalFormTrans Class?

If you ever tried to modify the LedgerJournalTransDaily form (the Ledger Jourlan Lines form) you would notice a forest of X++ codes executed on every click, initializations, closing, fields modifications… etc. Of course this makes sense because this form is basically the backbone of financial transaction of this Dynamics AX, which in turn the backbone of all modules of Dynamics AX.

One of the common classes executed in this form is LedgerJournalFormTrans class. Basically this class controls the controls of any form where LedgerJournalTrans table is a datasource for that form. It simply controls the visibility, edibility and validity of most of the controls on that form based on the “status” of the current Ledger Journal Trans and Ledger Journal Table. Whenever a user fills data, reads data, and clicks buttons and menu buttons.. a call for a method in that class is executed to control the new write/read/event.

Actually LedgerJournalFormTrans is an important class of a series of extended classes. Those classes are like the following:

  • JournalForm --> JournalFormTrans --> LedgerJournalFormTrans --> LedgerJournalFormTrans_Payment
  • JournalForm --> JournalFormTable --> LedgerJournalFormTable 

I believe from the name you could tell what all of those classes are all about.

Dynamics AX 6.0 – X++ Editor

I have read a very interesting article talking about the new editor of X++ that will be shipped as part of the new version of Dynamics AX, 6.0.

The new editor looks more “fashionable” than the current one. You could specify font styles, colors, sizes… etc. Also types of words that you write in the editor are now more colorful. Integers, operators, and others are now recognized in different colors.

Mainly, these are the features of the new Dynamics AX editor:

  • Support for multiple fonts and styles (comments are in a different font in italic)
  • Differentiated coloring of strings and numbers
  • Operators coloring
  • Change tacking margin

Here are some pics for it
