ActiveX

This article demonstrates how to add, access, remove, and configure ActiveX controls in a presentation using Aspose.Slides for .NET.

The checks verify stored controls and properties. Opening or executing ActiveX controls requires a compatible Windows host and its security permissions.

Download and run

Download the complete project, extract it, and open Example.sln or run:

dotnet restore Example.sln
dotnet run --project Example.csproj -- --mode evaluation

The download includes every case below, its fixture helpers and inputs. Program.cs runs all cases; use --action block-001 to run one independently. Outputs and an action report are written to the printed output directory. No previous example or working-directory setup is required. Evaluation adds a watermark and can truncate read-back text; the short fixtures still have explicit structural checks. For full text and no watermark, use --mode licensed --license PATH with your own valid license. See the setup guide for supported SDKs and native prerequisites.

Each printed CaseNN.cs file is compiled verbatim. The download checks each case in CaseVerification.cs before saving and after reopening the result.

Add an ActiveX Control

Insert a new ActiveX control and optionally set its properties.

using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case01()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        // Add a new ActiveX control.
        var control = slide.Controls.AddControl(ControlType.WindowsMediaPlayer, 50, 50, 100, 50);

        // Optionally set some properties.
        control.Properties["Value"] = "Text";

        presentation.Save("add_activex.pptm", SaveFormat.Pptm);

        VerifyCase01(presentation);
    }
}

Access an ActiveX Control

Read information from the first ActiveX control on the slide.

using System;
using System.Linq;
using Aspose.Slides;

internal static partial class Program
{
    static void Case02()
    {
        using var presentation = new Presentation(Seed("control"));
        var slide = presentation.Slides[0];

        // Access the first ActiveX control.
        var control = slide.Controls.FirstOrDefault();
        if (control != null)
        {
            Console.WriteLine($"Control Name: {control.Name}");
            Console.WriteLine($"Value: {control.Properties["Value"]}");
        }

        VerifyCase02(presentation);
    }
}

Remove an ActiveX Control

Delete an existing ActiveX control from the slide.

using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case03()
    {
        using var presentation = new Presentation(Seed("control"));
        var slide = presentation.Slides[0];

        if (slide.Controls.Count > 0)
        {
            // Remove the first ActiveX control.
            slide.Controls.RemoveAt(0);
        }

        presentation.Save("removed_activex.pptm", SaveFormat.Pptm);

        VerifyCase03(presentation);
    }
}

Set ActiveX Properties

Add a control and configure several ActiveX properties.

using Aspose.Slides;
using Aspose.Slides.Export;

internal static partial class Program
{
    static void Case04()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        // Add a Windows Media Player control and configure its properties.
        var control = slide.Controls.AddControl(ControlType.WindowsMediaPlayer, 50, 50, 150, 50);
        control.Properties["Caption"] = "Run";
        control.Properties["Enabled"] = "true";

        presentation.Save("set_activex_props.pptm", SaveFormat.Pptm);

        VerifyCase04(presentation);
    }
}
