How to check the size of a file

@noamwayOct 14.2005

Hello all,

I let the users to upload files and not only images.
I want before the file upload to check the size of the file.

I now how to do that with images but not with files.

Does any one have an idea?

Thanks

@konithomimoOct 14.2005 — #It isn't really possible. The best thing to do is to set a file limit or to upload the file to a temp folder and then have a server side script that checks the size, and if it is to big then delete it and alert the user.

[CODE]<HTML>
 <Head>
 <Script type="text/javascript">
 
  function getStats(fName){
 
   var fullName = fName;
   var shortName = fullName.match(/[^/\]+$/);
   document.Form1.dispSize.value = fileSize(fullName);
   document.Form1.dispName.value = shortName;
  }
 
 </Script>
 <Script type="text/vbscript"> 
 
  Function fileSize(fileSpec)
 
   Set fso = CreateObject("Scripting.FileSystemObject")
   Set contentFile = fso.GetFile(fileSpec)
   isSize = contentFile.Size
   fileSize = isSize
   Set contentFile = Nothing
   Set fso = Nothing
 
  End Function
 
 </Script>
 </Head>
 <Body>
 <Form name='Form1'>
 Choose a file: <input type='file' onchange="getStats(this.value)"><br>
 File Name: <input name='dispName' size='20'><br>
 File Size: <input name='dispSize' size='10' readonly><br>
 <input type='reset'><br>
 <input type='submit' value="Submit">
 </Form>
 </body>
 </html>[/CODE]

You may be another idea?

I don't want the user upload a 10MB file and then tell him it's not ok.

@MjhLkwdOct 14.2005 — #I wrote "IE only" at the top of my response.

The code is what it is.

JavaScript alone isn't capable of returning the size of a file/document.

You could place a text "notice" in your page, informing users beforehand that ActiveX will check the size of the file.

You know, sometimes half of a solution is better than nothing.
