For reference, I replied to the same question in the thread SetAttribute of xmlelement is not including complete string name during XML export.

Gopal, you've attached tags for both "Microsoft Dynamics AX (current version)" (= Dynamics 365 for Finance and Operations) and AX 2012. Which one are you actually talking about?

Hi Martin,

Actually i'm trying to create a table through X++ code, to generate a XML file in D365 format which create a table in D365 VS IDE. As part of it i'm facing issues to create an attribute for a fields in format

<AxTableField i:type="AxTableFieldString" xmlns="">

When i looked into the standard table XML it looks like below.

based on your suggestion on previous reply link (https://community.dynamics.com/ax/f/33/t/251536). It doesn't seems to work in my case.

I have used XMLElement.SetAttribute2() as fallows here i have pasted my logic.

Input:
nodeTableFields = nodeAXTable.appendChild(xmlDoc.createElement('Fields'));
xmlElementAxTableField = nodeTableFields.appendChild(xmlDoc.createElement('AxTableField'));
xmlElementAxTableField.setAttribute2('type','AxTableFieldString','');

Output:
<Fields>
<AxTableField d3p1:type="" xmlns:d3p1="AxTableFieldString" />
</Fields>

Kindly suggest for the resolution :-).

Having your ERP system (a web application) generating source code for Visual Studio sounds like a strange idea to me.

Wouldn't the right approach be creating a Visual Studio add-in and using the existing API to create a table instead of generating the file all by yourself? I see that IMetaModelService (in Microsoft.Dynamics.AX.MetaData.dll) has a method called CreateTable().

HI Martin,

Thank you for the reply.

As you mentioned in the previous reply to use some .dll, could you please be more specific, which .dll I need to pick.

Please refer below screenshot, I cannot find IMetaModelService class in dll.

Have explored in D365 to find such .dll's which would have similar characteristics like TreeNode classes(AX 2012). I could manage to find the only accessing/reading of D365 "Application explorer ", But no luck to create objects in D365 VS IDE. As a sample test, I was trying to create a sample table.

Able to create sample demo “Table” in VS for D365 through X++ code by generating XML file, And, we also have checked the file for Metadata, which gets created along with "full build of application" and it is available in the right local folder

Note: 1. Able to create a proper table structure with Method along with code inside, Fields group and index.

2. still have the bad luck to create Fields and relations on the table because of attribute : i:type = "xyz" xmlns = "" on-field tag node.

Please refer https://community.dynamics.com/ax/f/33/t/288007 from my post regarding creating the object in D365.

It's under Service sub-namespace, if I remember it correctly.

Here is a crude example of creating a class:

using Microsoft.Dynamics.AX.Metadata.MetaModel; using Microsoft.Dynamics.Framework.Tools.AddIns.Common; using Microsoft.Dynamics.Framework.Tools.Extensibility; using Microsoft.Dynamics.Framework.Tools.MetaModel.Core; using Microsoft.Dynamics.Framework.Tools.ProjectSystem; using System; using System.Collections.Generic; using System.ComponentModel.Composition; using System.Linq; using System.Text; using System.Threading.Tasks; namespace XppDevs.AddinsDemo { /// <summary> /// Demonstrates how to add a new class to the the active project. /// </summary> // This add-in is available from Dynamics AX > Addins menu. [Export(typeof(IMainMenu))] public class AddClassMenuAddIn : MainMenuBase { private const string addinName = "AddClassDemoAXAddIn"; // Caption is shown to users in the Addins menu. public override string Caption => AddinResources.AddClassAddInCaption; public override string Name => addinName; #region Callbacks /// <summary> /// Called when user clicks on the add-in menu /// </summary> /// <param name="e">The context of the VS tools and metadata</param> public override void OnClick(AddinEventArgs e) { try { // Find project to work with VSProjectNode project = LocalUtils.GetActiveProject(); // An alternative way is calling ProjectHelper.GetProjectDetails(), but it's not consistent // with how projectService.AddElementToActiveProject() determines the active project. // ProjectHelper return the startup project, which doens't have to be the active project. if (project == null) { throw new InvalidOperationException("No project selected."); } // Create a new class AxClass axClass = new AxClass() { Name = "MyNewClass", IsAbstract = true // Set a property for demonstration }; // Find metamodel service needed below // Find current model //ModelInfo model = metaModelService.GetModel(ProjectHelper.GetProjectDetails().Model); ModelInfo model = project.GetProjectsModelInfo(); // Prepare information needed for saving ModelSaveInfo saveInfo = new ModelSaveInfo { Id = model.Id, Layer = model.Layer }; // Create class in the right model var metaModelProviders = ServiceLocator.GetService(typeof(IMetaModelProviders)) as IMetaModelProviders; var metaModelService = metaModelProviders.CurrentMetaModelService; metaModelService.CreateClass(axClass, saveInfo); // Add the class to the active project var projectService = ServiceLocator.GetService(typeof(IDynamicsProjectService)) as IDynamicsProjectService; projectService.AddElementToActiveProject(axClass); } catch (Exception ex) { CoreUtility.HandleExceptionWithErrorMessage(ex); } } #endregion } }

This is from the time when AX 7 was released for the first time and I played a bit with these APIs. It's likely that others have built something more sophisticated in recent years.

I have resolved the creating I:Type Attribute by using below line of code.

"xmlAttributeAxTableField = xmlDoc.createAttribute3('i','type','www.w3.org/.../XMLSchema-instance&;);"
