Altova XMLSpy 2024 Enterprise Edition

The C# programming language can be used to access the Application API functionality. You could use Visual Studio 2012/2013/2015/2017/2019/2022 to create the C# code, saving it in a Visual Studio project. Create the project as follows:

 

1.In Microsoft Visual Studio, add a new project using File | New | Project.

2.Add a reference to the XMLSpy Type Library by clicking Project | Add Reference. The Add Reference dialog appears. Browse for the XMLSpy Type Library component, which is located in the XMLSpy application folder, and add it.

3.Enter the code you want.

4.Compile the code and run it.

 

Example C# project

Your XMLSpy package contains an example C# project, which is located in the API\C# subfolder of the Examples folder :

 

 

Windows 7, Windows 8, Windows 10, Windows 11

C:\Users\<username>\Documents\
Altova\XMLSpy\2024\Examples

 

You can compile and run the project from within Visual Studio 2012/2013/2015/2017/2019/2022. The code listing below shows how basic application functionality can be used. This code is similar to the example C# project in the API Examples folder of your application package, but might differ slightly.

 

Platform configuration

If  you have a 64-bit operating system and are using a 32-bit installation of XMLSpy, you must add the x86 platform in the solution's Configuration Manager and build the sample using this configuration. A new x86 platform (for the active solution in Visual Studio) can be created in the New Solution Platform dialog (Build | Configuration Manager | Active solution platform | <New…>).

 

What the code listing below does

The example code listing below creates a simple user interface (screenshot below) with buttons that invoke basic XMLSpy operations:

 

CSInterfaceForm

 

Start XMLSpy: Starts XMLSpy, which is registered as an automation server, or activates the application if it is already running.

Open OrgChart.pxf: Locates one of the example documents installed with XMLSpy and opens it. If this document is already open it becomes the active document.

OnDocumentOpened Event On/Off: Shows how to listen to XMLSpy events. When turned on, a message box will pop up after a document has been opened.

Open ExpReport.xml: Opens another example document.

Toggle View Mode: Changes the view of all open documents between Text View and Authentic View. The code shows how to iterate through open documents.

Validate: Validates the active document and shows the result in a message box. The code shows how to handle errors and COM output parameters.

Shut down XMLSpy: Stops XMLSpy.

 

You can modify the code (of the code listing below or of the example C# project in the API Examples folder) in any way you like and run it.

 

Compiling and running the example

In the API Examples folder, double-click the file AutomateXMLSpy_VS2008.sln or the file AutomateXMLSpy_VS2010.sln (to open in Visual Studio 2012/2013/2015/2017/2019/2022). Alternatively the file can be opened from within Visual Studio (with File | Open | Project/Solution). To compile and run the example, select Debug | Start Debugging or Debug | Start Without Debugging.

 

Code listing of the example

Given below is the C# code listing of the basic functionality of the form (Form1.cs) created in the AutomateXMLSpy example. Note that the code listed below might differ slightly from the code in the API Examples form.The listing below is commented for ease of understanding. Parts of the code are also presented separately in the sub-sections of this section, according to the Application API functionality they access.

 

The code essentially consists of a series of handlers for the buttons in the user interface shown in the screenshot above.

{

   public partial class Form1 : Form

   {

       public Form1()
