AX - Scan a document

There are a few ways to scan a document in AX.
Best way is to use Windows Image Acquisition (WIA). This comes standard from Windows Vista and up. Previous version you had to download "Windows Image Acquisition Automation Library v2.0" from Microsoft.

Without getting into too much detail. Here is the code:
static void scanDocument(Args _args)
{
    COM               commonDialog;
    COM               imageFile;
    str               wiaFormatJPEG     = "{B96B3CAE-0728-11D3-9D7B-0000F81EF32E}";
    str               wiaFormatBMP      = "{B96B3CAB-0728-11D3-9D7B-0000F81EF32E}";
    str               wiaFormatPNG      = "{B96B3CAF-0728-11D3-9D7B-0000F81EF32E}";
    str               wiaFormatGIF      = "{B96B3CB0-0728-11D3-9D7B-0000F81EF32E}";
    str               wiaFormatTIFF     = "{B96B3CB1-0728-11D3-9D7B-0000F81EF32E}";
    InteropPermission perm;
    ;

    // Set code access permission to help protect the use of the
    // COM object.
    perm = new InteropPermission(InteropKind::ComInterop);
    if (perm == null)
    {
        return;
    }
    // Permission scope starts here.
    perm.assert();

    commonDialog = new COM("WIA.CommonDialog");

    if (commonDialog != null)
    {
        imageFile = commonDialog.ShowAcquireImage(
                1,
                1,
                65536,
                wiaFormatJPEG,
                false,
                true,
                false);

        if (WinAPI::fileExists("C:\\Temp\\c\\AXtestb.jpg"))
        {
            info('file exist');
        }
        else
        {
            imageFile.SaveFile("C:\\Temp\\c\\AXtestb.jpg");
        }
    }

    // Close code access permission scope.
    CodeAccessPermission::revertAssert();
}

Ideas:

  • What you could do is integrate this into the document handling classes in AX and make this available as a feature on the document handling form. ie. Scan and attach a document
  • You could use the same for Web Cams and a few other devices

AX - How to use Map and MapEnumerator

Similar to Set class, Map class allows you to associate one value (the key) with another value. Both the key and value can be any valid X++ type, including objects. The types of the key and the value are specified in the declaration of the map. The way in which maps are implemented means that access to the values is very fast. Below is a sample code that sets and retrieves values from a map. static void checkItemNameAliasDuplicate(Args _args) { inventTable inventTable; Map map; MapEnumerator mapEnumerator; NameAlias nameAlias; int counter = 0; ; map = new Map(Types::String, Types::Integer); //store into map while select inventTable { nameAlias = inventTable.NameAlias; if (!map.exists(nameAlias)) { map.insert(nameAlias, 1); } else { map.insert(nameAlias, map.lookup(nameAlias) + 1); } } //retrieve fro

AX - How to use Set and SetEnumerator

The Set class is used for the storage and retrieval of data from a collection in which the values of the elements contained are unique and serve as the key values according to which the data is automatically ordered. You can create a set of primitive data types or complex data types such as a Class, Record or Container. Below is sample of a set of records. static void _Set(Args _args) {     CustTable       custTable;     Set             set = new Set(Types::Record);     SetEnumerator   setEnumerator;     ;     while select custTable     {         if (custTable && !set.in(custTable))         {             set.add(custTable);         }     }     if (!set.empty())     {         setEnumerator = set.getEnumerator();         setEnumerator.reset();         while (setEnumerator.moveNext())         {             custTable = setEnumerator.current();             info(strfmt("Customer: %1",custTable.AccountNum));         }     } } Common mistake when creating a set of recIds

Approve Workflow via email using template placeholders #Dyn365FO

Dynamics 365 for Finance and Operations has placeholders which can be inserted into the instructions. Normally you would want this to show up in the email that is sent. One of the most useful ones is the URL link to the exact record that you are approving. In the workflow configurations use the placeholder and build up your message. Towards the end it has workflow specific ones. The URL token is %Workflow.Link to web% . For the technical people the token is replaced in this class WorkflowDocumentField. This is what I inserted into my email template. <BODY> subject: %subject% <BR> message: %message% <BR> company: %company% <BR> for: %for% <BR> </BODY> Should look like this. The final result looks like this. If you debug these are the place holders that are put together.
