File Upload

[Craig Dahlinger]

Is there a way to use the <Input Type="file> control to just browse for file
names and not actually upload the file. I only want to provide a utillity
for the end user to browser for the file path, which is on a network share.
I do not want the file uploaded. I cannot seem to stop the control from
uploading the file, even when I remove the runat="server" tag.

Any ideas are welcome...

Thanks

The article below has a list of 4 or 5 requirements that must be met in
order to upload a file. It would stand to reason that if you make sure
those requirements are not met that no upload would take place.

There's also a paragraph about security which explains that, outside of the
local machine zone, you can only get the name of the file, but not the
path.

Dear Craig,

Already, the input type="file" just shows the file path. Only if you write the logic for uploading it to the server, the user may be able to do the same.

if you just provide input type=file, it will just show the path which can be browsed.

So just provide the same and dont write the logic for uploading to the server.

Hope it helps.

couldn't figure it out

This was bothering me, since I wasn't sure you could use clearAttributes() properly on a file input. Sadly, after experimenting for a while, the only thing I could find that cleared the value was by storing the outerHTML in a variable on page load, and then restoring that variable to the control before submit.

var inputCachedHTML;
function BeforeFormSubmit() {
document.getElementById('txtXMLOutput').value +=
document.getElementById('myFileInput').value;
document.getElementById('myFileInput').outerHTML = inputCachedHTML;
return true;
}

In the body tag, use:
onload="inputCachedHTML = document.getElementById('myFileInput').outerHTML;"

I hope that's useful to someone.
