If you use Java servlet or JSP, Apache's Commons FileUpload package (open source) will be very useful to you.

(A little clarification below.)You can either use the readonly attribute or the disabled attribute:<input type="text" readonly="readonly" ...<input type="text" disabled="disabled" ...The difference is that the disabled attribute will gray out the text field while the readonly attribute will not. On Firefox, the text in a disabled text field cannot be selected and copied to the clipboard.You can also use JavaScript to set the readonly or disabled attribute:var field = document.getElementById('fieldId');field.readOnly = true;var field = document.getElementById('fieldId');field.disabled = true;
