Imports Leadtools.WinForms 
Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.Drawing 
 
Private Sub viewer_AnimationModeChanged(ByVal sender As Object, ByVal e As EventArgs) 
    Dim viewer As RasterPictureBox = CType(IIf(TypeOf sender Is RasterPictureBox, sender, Nothing), RasterPictureBox) 
    Dim s As String = String.Format("AnimationModeChanged Event: {0}", viewer.AnimationMode.ToString()) 
    MessageBox.Show(s) 
End Sub 
Public Sub RasterPictureBox_AnimationModeChanged(ByVal viewer As RasterPictureBox) 
    AddHandler viewer.AnimationModeChanged, AddressOf viewer_AnimationModeChanged 
 
    Select Case viewer.AnimationMode 
        Case RasterPictureBoxAnimationMode.Infinite 
            viewer.AnimationMode = RasterPictureBoxAnimationMode.UseImageGlobalLoop 
 
        Case RasterPictureBoxAnimationMode.UseImageGlobalLoop 
            viewer.AnimationMode = RasterPictureBoxAnimationMode.Infinite 
    End Select 
 
    viewer.PlayAnimation() 
    RemoveHandler viewer.AnimationModeChanged, AddressOf viewer_AnimationModeChanged 
End Sub

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
private void viewer_AnimationModeChanged(object sender, EventArgs e) 
{ 
   RasterPictureBox viewer = sender as RasterPictureBox; 
   string s = string.Format("AnimationModeChanged Event: {0}", viewer.AnimationMode.ToString()); 
   MessageBox.Show(s); 
} 
public void RasterPictureBox_AnimationModeChanged(RasterPictureBox viewer) 
{ 
   viewer.AnimationModeChanged += new EventHandler(viewer_AnimationModeChanged); 
 
   switch (viewer.AnimationMode) 
   { 
      case RasterPictureBoxAnimationMode.Infinite: 
         viewer.AnimationMode = RasterPictureBoxAnimationMode.UseImageGlobalLoop; 
         break; 
 
      case RasterPictureBoxAnimationMode.UseImageGlobalLoop: 
         viewer.AnimationMode = RasterPictureBoxAnimationMode.Infinite; 
         break; 
   } 
 
   viewer.PlayAnimation(); 
   viewer.AnimationModeChanged-= new EventHandler(viewer_AnimationModeChanged); 
}
