    Distinct File Uploads

    Reply Quote
    Is there a way to prevent the upload queue from having multiple entries of the same file?
     
    how would one do this?

    this code works great for canceling a selection which contains a file that is already queued up but it cancels the entire selection including files which have not yet been queued up. is there a way from preventing the queue up of only files that are present and allow the queue up of new files within the same selection?
     
    for example:
    if i have files 1,2,3, and 5 on the queue and then select files 1,2,3,4,and 5. i would like only file 4 to be queued up.
     
     
    can this be done with your control?

    Hi,
     
    Currently the AjaxUploader do not provide javascript API to process each files yet.
     
    We will provide that feature in the future, but maybe a long days later.

    Hi,
     
    Now you can cancel the item of the Select event.
     
    Please download the last version and try :
     
        function CuteWebUI_AjaxUploader_OnSelect(files)
        {
      var sames=[];
      var items=uploader.getitems();
      for(var i=0;i<files.length;i++)
      {
       var file=files[i];
       var exists=false;
       for(var j=0;j<items.length;j++)
       {
        var item=items[j];
        if(item.FileName==file.FileName)
        {
         exists=true;
        }
       }
       if(exists)
       {
        sames.push(file.FileName);
        file.Cancel();
       }
      }
      if(sames.length>0)
      {
       alert("These file(s) are already in the queue : \r\n\t"+sames.join('\r\n\t'));
      }
        }
     
    Regards,
    Terry

    this codes seems to work "kind of". I have two <CuteWebUI:UploadAttachments> controls on the same page for one of the controls the CuteWebUI_AjaxUploader_OnSelect  function is triggered but for the other the one that actually does multiple files uploads it does not.
    Also "uploader" in the provided code I assume refers to the <CuteWebUI:UploadAttachments> control correct?

    Hi,
     
    last version means 200909XX ( you can check the file property dialog)
     
    Can you post some code to explain your case ?
     
    CuteWebUI_AjaxUploader_OnSelect should trigger to all uploader controls.

    I realised why it wasnt triggering and it had somethign to do with my calling of  "uploader.getitems();" this broke. I dont think I have the latest version of the dll. Where can I get the latest version when I go to downloads it says the latest versions is from a year ago

    also I noticed "uploader.getitems();" was not in the AJAX uploader developer guide "class reference" you have available. when will the new class reference with the updates info be available?

    is the "CuteWebUI.AjaxUploader.dll " files provided in the download different in any way? like is the one included in the "advancedCS20" folder different from the one in the "Framework 2.0-Csharp" folder? also how can I find out the version of the dll file?

    Hi,
     
    They are the same file .
     
    When you want to check the file version , you can open the file property dialog , and check the title of the detail tab.
