The Microsoft Dynamics AX client includes a COM interface that you can use to open a form. As a result, you can use COM to open a form from another application or from a script file. In addition, you can create a desktop shortcut that uses the script to open the form. For more information about COM and the Microsoft Dynamics AX client, see Using COM to Open a Form from an Application.

Using a .NET Application to Open a Form

The following steps show how to use COM to open a form from an application built by using the Microsoft .NET Framework. You can use the Dynamics AX COM object to open a form in the Microsoft Dynamics AX workspace. Beginning with Microsoft Dynamics AX 2012 R2, you can also specify the partition for the workspace. For more information about partitions, see How to: Specify the Partition for the Form.

To add a reference to the Dynamics AX Client Type Library

In the Solution Explorer of Visual Studio, expand your project. Right-click on the project name and then click References.
Click Add Reference. The Add Reference window appears.
Click the COM tab, scroll down the list of components, click Dynamics AX Client 1.0 Type Library, and then click OK.
AxClientLib is added to the list of references for your project. AxClientLib is the namespace for the .NET interop assembly. In a .NET application, you use the interop assembly to interact with the Dynamics AX COM object.

To use the DynamicsAxApplication interface

Add the AxClientLib namespace to your project.

The following code example shows how to import the namespace to a C# application.

    using AxClientLib;

Create an instance of the DynamicsAxApplication interface.

The following code example creates an instance of the DynamicsAxApplication interface.

    AxClientLib.DynamicsAxApplication axComClient = new AxClientLib.DynamicsAxApplication();

Use the OpenMenuItem method of the DynamicsAxApplication interface to open the form. To specify the form, you supply a company name, the name of a menu item, and the type of the menu item.

The following code example shows how to use OpenMenuItem. Notice how the method parameters specify a company name, a menu item, and that the menu item is a Display type. AxMenuType is an enumeration found in the AxClientLib namespace.

    axComClient.OpenMenuItem("CEU", "CustTableListPage", AxClientLib.AxMenuType.DisplayMenu);

Using a Shortcut to Open a Form

You can also use COM in a script file that can open a specified form. This enables you to create a desktop shortcut that opens a frequently used form. The following steps show how to create a script file and how to create a desktop shortcut that opens a form.

To use the DynamicsAx.Application interface

Use a text editor to create a file for your script. Specify the name and type of your script file.

For example, create a file that is named OpenAxMenuItem.vbs.
Create an instance of the DynamicsAx.Application interface.

The following code example uses CreateObject to create the DynamicsAx.Application interface.

       Set objDynamicsAx = CreateObject("DynamicsAx.Application")

To open a form, use the OpenMenuItem method of the DynamicsAx.Application interface. The method requires that you specify a company, a menu item, and the type of the menu item.

The following code example uses VBScript to open a form. Notice how the script enables you to specify the company, menu item, and menu item type with the command line arguments. Also notice how the command line values are used with the OpenMenuItem method.


        '--------------------------------------------------
        '
        'Opens the Dynamics Ax Menu Item that was specified.
        '
        'Usage:
        '    openAxMenu -c <companycode> {-d "<displaymenu>" | -a "<actionmenu>" | -o "<outputmenu>"}
        '    openAxMenu [-help|-?]
        '
        '--------------------------------------------------
        
        Option Explicit
        
        Dim objDynamicsAx, oArgs, ArgNum
        Dim companyName, displayMenuName, actionMenuName, outputMenuName
        
        Set oArgs = WScript.Arguments
        ArgNum = 0
        companyName=""
        displayMenuName=""
        actionMenuName=""
        outputMenuName=""
        
        While ArgNum < oArgs.Count
            Select Case LCase(oArgs(ArgNum))
                Case "-c":
                    ArgNum = ArgNum + 1
                    companyName = oArgs(ArgNum)
                Case "-d":
                    ArgNum = ArgNum + 1
                    displayMenuName = oArgs(ArgNum)
                Case "-a":
                    ArgNum = ArgNum + 1
                    actionMenuName = oArgs(ArgNum)
                Case "-o":
                    ArgNum = ArgNum + 1
                    outputMenuName = oArgs(ArgNum)
                Case "-help","-?":
                    Call DisplayUsage
                Case Else:
                    Call DisplayUsage
            End Select
            ArgNum = ArgNum + 1
        Wend
        
        If oArgs.Count = 0 Then
            Call DisplayUsage
        ElseIf (displayMenuName="" And actionMenuName="" And outputMenuName="") Then
            WScript.Echo "ERROR: You must specify the menu item to launch"
            Call DisplayUsage
        Else
           Set objDynamicsAx = CreateObject("DynamicsAx.Application")
            If displayMenuName <> "" Then
                 objDynamicsAx.OpenMenuItem companyName, displayMenuName, 1
            ElseIf actionMenuName <> "" Then
                 objDynamicsAx.OpenMenuItem companyName, actionMenuName, 3
            ElseIf outputMenuName <> "" Then
                objDynamicsAx.OpenMenuItem companyName, outputMenuName, 2
            End If
        End If
        
        'Display the usage for this script
        'Usage:
        '    openAxMenu -c <companycode> {-d "<displaymenu>" | -a "<actionmenu>" | -o "<outputmenu>"}
        '    openAxMenu [-help|-?]
        Sub DisplayUsage
            WScript.Echo "Usage:"
            WScript.Echo "  openAxMenu.vbs [-c <companyCode>] {-d " & _
               Chr(34) & "<displayMenuItemName>" & Chr(34) & " | -a " & _
               Chr(34) & "<actionMenuItemName>" & Chr(34) & " | -o " & _
               Chr(34) & "<outputMenuItemName>" & Chr(34) & "}"
            WScript.Echo "  openAxMenu [-help|-?]"
            WScript.Echo ""
            WSCript.Quit
        End Sub

Save the file.

To create a desktop shortcut that runs the script

Right-click the desktop where you want to add the shortcut. Click New and then click Shortcut. The Create Shortcut window appears.
In the Type the location of the item box, type the name of the script file that you created. Include the path of the folder where you put the script file. Add the command line parameters. Click Next.

The following example uses a script file to open the Customers form. The shortcut uses the script from the previous procedure that was saved to a file that is named OpenAxMenu.vbs. Notice how command line arguments are used to specify the company, the menu item, and the menu item type. In the example, –d specifies that the menu item is a Display menu item.
```
C:\Users\LocalUser\Desktop\OpenAxMenu.vbs –c CEU –d "CustTable"
```
In the Type a name for this shortcut box, type the name for the shortcut. Click Finish.

For example, type View Customer to specify the form that opens when you double-click the shortcut.
To open the form, double-click the shortcut.
