Hello!

I was wondering if anyone was able to validate the size on an image file in pixels? For example, validate that an image is 150x150? I've done a brief javascript for it, but it is very temperamental.

Any ideas?

Thanks!

I left them on my own, I prefer yellow than blue ...

But It's still a pleasure to read Codestore day after day !

Sorry to hear that Sylvain. Did they get rid of you for sharing secrets? It should cheer you up to know how many people your little secret has helped.

Glad to see you are still reading ;o)

Nice job, Jake!

Thought you should have at least one unreserved pat on the back. :o)

As for the user having to wait for a failure report, if the form clearly states the file size limit, as Jakes example shows, then shame on them for not looking at their file size before clicking Upload.

Like an old collegue once told me, "Don't try to idiot proof your applications... the idiots won't appreciate it."

Sean, if you could do in JavaScript, trust me, I would have talked about it.

The reason you can't is that it would require giving the browser access to the OS and that's a big no-no.

Jake -

The problem I see: if this is handled by the server, the user is going to have to wait a long time for the file to upload, and then get a "sorry! can't do this" message. Wouldn't it be better to try to get the browser to figure this out using Javascript?

Not that I practice what I'm preaching here... I use the dreaded validation field method that you are improving on. Look forward to the reasons why this is bad.

Thanks Jorge. This would be nice if you could gaurantee the access to install and run ActiveX objects or run .hta files. Not everybody can and it would probably be restricted to intranets...

You can but as I'm writing at the moment in the article, you wouldn't want to. The LotusScript method is much better.

Jake,

You can also just put a hidden editable text field on the form and add the following to the Input Validation:

@If(@Attachments=1;@If(@AttachmentLengths>20000;@Failure("Web Page>Image Size ValidationImage is too large

The image that you have selected is greater than 20K in size

Image size:"+@Text(@Round((@AttachmentLengths/1000)))+"K

Click here to try again ");@Success);@Success)
