Visual BasicCopy Code
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
C#Copy Code
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); 
}
