    How to validate a file being uploaded across a SQL db?

    Reply Quote

    So I am trying to validate the file being uploaded to a database to check if the name exists or not prior to the upload. Is there a way to do that using the uploader?

     

    Any help would be appreciated.

    Hi mskhan,

     

    You can get the upload file name at server side and client side both.

     

    at server side in event FileUploaded.

     

    1. protected void Uploader1_FileUploaded(object sender, UploaderEventArgs args) 
    2. { 
    3.     //get upload file name by args.FileName 
    4.     //if exists delete it by args.Delete(); 
    5. } 
     

    At client side in API CuteWebUI_AjaxUploader_OnSelect(files)

     

    1. <script> 
    2.     function CuteWebUI_AjaxUploader_OnSelect(files) { 
    3.         for (var i = 0; i < files.length; i++) { 
    4.             var name = files[i].FileName; 
    5.             if (file exist) { 
    6.                 files[i].Cancel(); 
    7.             } 
    8.         } 
    9.     } 
    10. </script> 
     

    Regards,

    Ken,

     

    Thanks for getting back to me. I am trying something similar but its not working. I am trying to query into a Recordset and possibly find the file selected by the user within the recordset and if it doesn't exist then alert the user of it.

     

     

     

    1. <script>  
    2. function CuteWebUI_AjaxUploader_OnSelect(files) {  
    3.   
    4.                  <%  
    5.                 Set AdoCon=Server.CreateObject("ADODB.Connection")  
    6.                 Set AdoRec=Server.CreateObject("ADODB.Recordset")  
    7.                 AdoCon.ConnectionString="Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Password=*******;Initial Catalog=AFDDB_DEVY;Data Source=MOMENTUMTEST"  
    8.                 AdoCon.Open  
    9.                 AdoRec.Open "Select Custid from APPLICATION",AdoCon  
    10.                 str=AdoRec.GetString()  
    11.                   %>  
    12.   
    13.   
    14.                 for (var i = 0; i < files.length; i++) {   
    15.                 var name = files[i].FileName;   
    16.                 if (str=name) {   
    17.                     alert(name);  
    18.                     'files[i].Cancel();   
    19.                     }   
    20.                 }    
    21.                   
    22.                   
    23.                   <%  
    24.                 AdoRec.close  
    25.                 AdoCon.close  
    26.                 set AdoRec = Nothing  
    27.                 set AdoCon = Nothing  
    28.                     %>          
    29.                    
    30. </script>  
     I am just having it show me an alert but its not working. If I do a Response.Write(str) Then it does show me the query response from the database fine.

     

    Do you know the issue here?

     

    Thanks,

    Khan

    Hi Ken,

     

    Thanks for that.

     

    However, it still does not show me the alert. Am I doing this wrong? Can this not be done in that function?

     

    Do you know of a better way?

     

    Thanks,

    Please try the example page below.

    Hi Ken,

     

    Hope you had a great Christmas. Thanks your reply.

     

    However, this still does not solve the issue at hand.

     

    1. <%    
    2.                Set AdoCon=Server.CreateObject("ADODB.Connection")    
    3.                Set AdoRec=Server.CreateObject("ADODB.Recordset")    
    4.                AdoCon.ConnectionString="Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Password=*******;Initial Catalog=AFDDB_DEVY;Data Source=MOMENTUMTEST"    
    5.                AdoCon.Open    
    6.                AdoRec.Open "Select Custid from APPLICATION",AdoCon    
    7.                str=AdoRec.GetString()    
    8.                  %>    
    9.    
    10.    
    11.                for (var i = 0; i < files.length; i++) {     
    12.                var name = files[i].FileName;     
    13.                if (str==name) {     
    14.                    alert(files[i].FileName);    
    15.                    'files[i].Cancel();     
    16.                    }     
    17.                }      
    18.                    
    19.                    
    20.                  <%    
    21.                AdoRec.close    
    22.                AdoCon.close    
    23.                set AdoRec = Nothing    
    24.                set AdoCon = Nothing    
    25.                    %>     
     

     

    I still am unable to validate across the database with the above code.

    For some reason str variable does not want to work against the name variable.

     

    Thanks,

    Khan

    Also, can you tell me if this would work to grab the filename without the extension?

     

    1. for (var i = 0; i < files.length; i++) {  
    2.       var name = files[i].FileName;  
    3.       var extension = System.IO.Path.GetfileNameWithoutExtension(file[i].FileName);  
    4.          var extensionless = name.substring(0, name.Length - extension.Length);  
    5.          alert(extensionless);  
    6.                               
    7.      }  
     Hasn't worked me.

    Hi maddybucks,

     

    Can you explain your question in detail? binding for what? for the uploader property? or the store location?
