Save the page to enter a file

Hello


I have a task where a user should be able to save the nput on a page in a file.
The page contains a form and a tabular presentation.
The user must also have the ability to download the recorded files and save the corresponding data in the database.
This is necessary for the possible inadequacies in internet connection and it is used in laptops.
I wonder what would be the easiest way to do it.
I thought that maybe it could be done so that the entire page is copied into the HTML and stored in a file. Then on download the corresponding input values of the objects are copied to the page and the page is then submitted. But how to copy the values of a BLOB?
And I guess that there is a better way to do it?

Any advice or comments would be really useful, because I have to get this loan soon.

Hmmm... If your users want to start to edit the report in the apex itself, but to continue the same change even after the network connection is lost?
I thought asking them to download excel first, edit (excel), and then upload it later.
If this is the case, regardless of what you do at the top entered values will remain in the user's browser. Of course, you can use a tabular form based on a collection and use ajax automatic backup of data from time to time, but even that won't be very effective.

Save the HTML code would probably be the only way (if they do not want to download excel). As I mentioned earlier, download this HTML file on an XML column and extract values from there. You can also combine approaches, by having a Javascript on the page dumps all the data in a text box in a separate comma structure which users can save a csv file, open in excel change I have and then transfer it too.

Whatever the method used, you have a slight problem (that you've neglected). Once the connection is lost, request of the form in a table Pagination no longer work, users can run only on a single page (the one that is responsible), is the same with downloading the report to Excel again who needs a request to the server (so the javascript method that I mentioned would have this problem again). Save the report together in an HTML page (by using a value large paging) or modifying an excel would probably be the only way then.

    Hello.

    I think this is a related issue of Windows, because it is the Manager to save the windows file that we are talking about here (right?). You should contact Microsoft for help with this one, I think. You expect to be able to delete entries simply by touching delete on your keyboard when they are concentrated (that is how it goes for the removal of the form entries specific autocomplete in Firefox), but I have not tried.

    When you save a page like this, 1 file and 1 file of the same name (as specified above) are saved in the specified location, keeping the two of them. In order to display the saved page, simply open the file (Firefox logo).

    IF you delete the folder, you can not view the saved page.

    Check and tell if its working.

  • PHP pages: output error check available and continues to save the page

    Hello

    I noticed that the error output check (green or red) in the Dreamweaver footer bar (on the left of "glimpses of the unit", "browser preview" and icons 'size of windows') is not available in the pages with the .php extension, .html to.

    In addition, Dreamweaver ask me to save the page whenever I change something.

    For example, if I use 'commands-> format source' in a .php page, Dremweaver ask me each time to save it to complete this command.

    Is this a normal behavior?

    I use the latest version, CC 2015 (7714 build), OS X Yosemite.

    No, this isn't a bug, it's how DW. DW needs to have the file saved to be able to produce live view, and Yes, it sucks that the characteristics of the Live view mode are lost when in Design mode.

    Live view is still in its infancy since Adobe has begun to put the elements in Live view mode. If all goes well, they will see a way to overcome the ongoing pop-up from happening.

    Regarding the PHP support, this has always been a minimum feature. If you want a good PHP editor, then there are a lot of options such as

    If you want a picture of façade one VI, you can use the method to obtain images of Panel (or the Tool of Capture of Code, which offers a range of screws for this).

    If you want a picture of the entire screen, you can simulate a button on the print screen, using the method of Clipboard.Get Image Application class to get a picture of the contents of the Clipboard. If you are looking for "screenshot" you should probably find a few examples already.

    All browsers do this caching.  This is to eliminate the need to keep the same things over and over again and so the download speed things up.  There are all kinds of ways to control this by clicking on the gear and then Internet options.

  • Why the Pages go through each file before opening one I clicked on that?

    When I click on a file I want in the Pages, the program passes through each file that I created before he gets to the one I want.  Is it possible to go directly to the file you want?

    Open the Pages with the SHIFT key is pressed, so it is not reopen previously open documents or close all your open documents before leaving the Pages.

  • Can I merge the pages in a single file, then when I download it gets all pages

    I would like to be able to merge 5 pages of a file into one for that when I download on a website it gets all pages.

    It seems to me you need to create a PDF file that contains all 5 pages of information, but on what paging has been disabled (if editing software includes this feature).  You can do that with Adobe Reader (it won't create or edit documents).

    Maybe free PDF Editor will do the trick: http://www.freedownloadscenter.com/Business/MS_Office_Add-ins/Free_PDF_Editor.html.

    It is possible that the ability to edit PDF files exists in the current version of OpenOffie (www.openoffice.org). He calls it hybrid PDF and I don't know what that means.

    Here's another free PDF Editor (and a free trial of another person) to: http://www.primopdf.com/index.aspx.

    I hope this helps.  Still, I don't understand how the site takes the PDF file and opens it in fact and extracts only the first page.  If it is completely copied, how is the program Web site knows there are several pages and accept only the first?  In any case, I guess they have a way to do it or you wouldn't post this question.  I would like to know if I'm still missing the point.  I don't see why you can't use Notepad, because that could ruin your layout - but maybe one of the programs above can help you.

    Good luck!
