If the following error occurs when displaying a report on the screen, you must set up a default printer in Windows.

OpenPrinter_1: rc:0 LastError:3012(0xbc4) No printer were found.

Sometimes you have to use special characters in the XML header of a method to document the code well. To get sure, that this header is still well-formed and is not identified as best practice deviation, you can use a CDATA section.

/// <version>
///  1.0
/// </version>
/// <summary>
/// <![CDATA[ Replaces following special characters: &, % ]]>
/// </summary>
private void someMethod()
{
    //...do something...
}

Without this CDATA section AX would spend the following BP-Deviation:

XML documentation is not well-formed.

To list all (shared-) pojects that carry a specific text in the name, you can use the following code.

static void searchProjectName(Args _args)
{
    ProjectNode projectNode;

    #AOTExport

    projectNode    = infolog.projectRootNode();
    projectNode    = projectNode.AOTfindChild(#expProjectShared);
    projectNode    = projectNode.AOTfirstChild();

    while(projectNode)
    {
        setPrefix(projectNode.name());

        if(strScan(projectNode.name(), "BR_", 0, 60))
        {
            info(projectNode.name());
        }

        projectNode    = projectNode.AOTnextSibling();
    }
}

To open the query-windows when opening a form, you can use the following code for example:

public void run()
{
    super();
    if(dataSourceName_ds.queryRun().prompt())
    {
        dataSourceName_ds.research();
    }
}

Using the CommaTextIo class you can import CSV files into Dynamics AX. The job shows a simple example of using this class.

static void importCSVFile(Args _args)
{
    Filename fileName = @"c:	empcsvimport.csv";
    CommaTextIo commaTextIo = new CommaTextIo(fileName, "r");
    container lineCon;

    commaTextIo.inFieldDelimiter(';');
    commaTextIo.inRecordDelimiter(' ');
    while (commaTextIo.status() == IO_Status::OK)
    {
        lineCon = commaTextIo.read();

        info(strFmt("%1 %2 %3", conPeek(lineCon, 1), conPeek(lineCon, 2), conPeek(lineCon, 3)));
    }
}

In principle, this would also work with the TextIo class (or AsciiIo), but it must be noted that these classes can provide unexpected results when, for eample the inFieldDelimiter - in my example a semicolon - occurs within a text.

The following sample file would otherwise be processed, as expected from the developer. The third column in the third row would be interpreted as two columns by the read()-method.

100;450,00;Customername1
101;1200,00;Customername2
102;50,28;"Customername 3; Second customername"

A simple example of how to create a purchase order line through code using AX<Table>-Class.

static void createPurchLine(Args _args)
{
    axPurchLine axPurchLine;
    purchLine purchLine;
   
    axPurchLine = AxPurchLine::newPurchLine(purchLine);
    axPurchLine.validateInput(true);
    axPurchLine.continueOnError(false);
   
    axpurchLine.parmPurchId("P00001");
    axpurchLine.parmItemId("1000");
    axPurchLine.parmPurchQty(10);
    axPurchLine.parmPurchPrice(24.50);
    axPurchLine.save();
}

If you need a so called AX-class can use the class AxGenerateAxBCClass.

Simply call this class in the AOT by right clicking and follow the wizard or use following job:

static void generateAXTableClass(Args _args)
{
    AxGenerateAxBCClass axGenerateAxBCClass;
    
    axGenerateAxBCClass = new AxGenerateAxBCClass();
    axGenerateAxBCClass.parmTableId(tableNum(MyNewTable));
    axGenerateAxBCClass.run();
}

A that way generated class must be modified sometimes, but using the wizard is much faster than creating the class manually.

If the table changes, for example when adding new fields, you simply call that AxGenerateAxBCClass again and the AX

-class will be extended accordingly.

How to use such AX

-classes, i've described here.
