Hi Terry,

 

I tried both on my aspx file and also the "SelectFile.aspx" inside CuteEditor.

 

<script type="text/javascript">
        function CuteEditor_AjaxUploader_OnError(msg)
        {
         alert(msg);
         uploader=this;
         uploader.setresumeoption("Cancel");
         return false;
        }
        
        function CuteWebUI_AjaxUploader_OnError(msg)
        {
         alert(msg);
         uploader=this;
         uploader.setresumeoption("Cancel");
         return false;
        }
