Commands for Working with Attachments

To obtain a file attached to the selected record or detail line through the web services API, you specify the Value command in the array of Command objects as follows:

• In the FieldName property, you specify the name of the file that should be obtained.
• In the LinkedCommand property, you specify the needed Attachment service command.

  To work with a file attached to a form, you use the Attachment service command of the object that corresponds to the Summary object. For example, to obtain a file attached to a stock item record on the Stock Items (IN202500) form, you use the Attachment service command of the IN202500StockItemSummary object.

  To work with the file attached to a detail line of a master-detail form, you use the Attachment service command of the object that corresponds to the Details object. For example, to obtain the file attached to a warehouse detail line of a stock item on the Stock Items form, you use the Attachment service command of the IN202500WarehouseDetails object.

The following code shows how to retrieve the file attached to a stock item record on the Stock Items form.

//stockItemsSchema is an IN202500Content object
var commands = new Command[]
{
  new Value 
  {
    Value = "AAMACHINE1", 
    LinkedCommand = stockItemSchema.StockItemSummary.InventoryID 
  },
  new Value 
  {
    FieldName = "T2MCRO.jpg", 
    LinkedCommand = 
     stockItemSchema.StockItemSummary.ServiceCommands.Attachment 
  }  
};
//context is a Screen object
var stockItemAttachment = 
 context.IN202500Export(commands, null, 1, false, true);
