请教老师，下面一段vb代码用在fox该怎么做？先引用Corel.Interop.VGCore.dll？然后代码该怎么改呢，代码放在哪里呢？

Imports Corel.Interop.VGCore

Module Module1

  Sub CreateTextInCorelDRAW(text As String, fontName As String, fontSize As Single)

    Dim pia_type As Type = Type.GetTypeFromProgID("CorelDRAW.Application.17")

    Dim app As Application = Activator.CreateInstance(pia_type)

    app.Visible = True

    Dim doc As Document = app.ActiveDocument

    If doc Is Nothing Then doc = app.CreateDocument()

    Dim shape As Shape = doc.ActiveLayer.CreateArtisticText(

      0.0, 0.0, text, cdrTextLanguage.cdrLanguageMixed,

      cdrTextCharSet.cdrCharSetMixed, fontName, fontSize,

      cdrTriState.cdrUndefined, cdrTriState.cdrUndefined,

      cdrFontLine.cdrMixedFontLine, cdrAlignment.cdrLeftAlignment)

  End Sub

  Sub Main()

    Try

      CreateTextInCorelDRAW("Hello, world", "Arial", 24.0F)

    Catch ex As Exception

      Console.WriteLine("Error occurred: {0}", ex.Message)

    End Try

  End Sub

End Module

下面是一段同样效果的C#代码，也是不清楚该怎么用在fox

using System.Text;

using System.Threading.Tasks;

using Corel.Interop.VGCore;

namespace TextCreatorCS

{

  class Program

  {

    static void CreateTextInCorelDRAW(string text, string fontName,

                                      float fontSize)

    {

      Type pia_type = Type.GetTypeFromProgID("CorelDRAW.Application.17");

      Application app = Activator.CreateInstance(pia_type) as Application;

      app.Visible = true;

      Document doc = app.ActiveDocument;

      if (doc == null)

        doc = app.CreateDocument();

      Shape shape = doc.ActiveLayer.CreateArtisticText(

        0.0, 0.0, text, cdrTextLanguage.cdrLanguageMixed,

        cdrTextCharSet.cdrCharSetMixed, fontName, fontSize,

        cdrTriState.cdrUndefined, cdrTriState.cdrUndefined,

        cdrFontLine.cdrMixedFontLine, cdrAlignment.cdrLeftAlignment);

    }

    static void Main(string[] args)

    {

      try

      {

        CreateTextInCorelDRAW("Hello, world", "Arial", 24.0f);

      }

      catch (Exception ex)

      {

        Console.WriteLine("Error occurred: {0}", ex.Message);

      }

    }

  }

}

全局代码

Public Sub CreateTextInCorelDRAW(text As String, fontName As String, fontSize As Single)

Dim pia_type As Type = Type.GetTypeFromProgID("CorelDRAW.Application.17")

Dim app As object = Activator.CreateInstance(pia_type)

app.Visible = True

Dim doc As object = app.ActiveDocument

If doc Is Nothing Then doc = app.CreateDocument()

Dim shape As object = doc.ActiveLayer.CreateArtisticText( _
0.0, 0.0, text, Corel.Interop.VGCore.cdrTextLanguage.cdrLanguageMixed, _
Corel.Interop.VGCore.cdrTextCharSet.cdrCharSetMixed, fontName, fontSize, _
Corel.Interop.VGCore.cdrTriState.cdrUndefined, Corel.Interop.VGCore.cdrTriState.cdrUndefined, _
Corel.Interop.VGCore.cdrFontLine.cdrMixedFontLine, Corel.Interop.VGCore.cdrAlignment.cdrLeftAlignment)

End Sub
