I'm having trouble working on FileReference download(URL) function. I needed to automatically download the files in a particular space on my harddisk but the SAVE AS dialog always displays. can I make it automatically download in a certain place on my disk?
I'm going to assume "automatically download" means "save" here. Nope, If you use FileReference (or File in AIR), there's no way to automatically save without showing the Save As dialog box.
If you don't need to access the file outside of the app, then take a look at the SharedObject class: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/SharedObject.html. By default you can create SharedObjects of up to 100KB without needing the client's permission (see the description of getLocal()), which should be fine for more simple text or xml info - you can compress it using ByteArray if you want to save space. Any more than that and a small dialog will open asking permission. Once you've given permission however, it won't ask again.

I'm implementing a WebDAV file server using the ITHit WebDave engine, i have the following problem
When i list the files and open one of them i get the ReadAsync method called, i provide the content and the file is opened correctly
However any changes i make to the file can't be saved, i get an error saying
A device attached to the system is not working
I looked at the file system samples and implemented support based on the FileSystemStorage.AspNetCore sample,
From what can understand the WriteAsync method is used when creating new files, should i expect for WriteAsync to also be called for file edits that need to be changed?
Am i wrong in the assumption that DavFile.WriteAsync will be called with a stream for the updated content?
If WriteAsync is not the right location to save updates to a file, could you provide some guidance on the process of saving changes to existing files?
Edited to add:
Now i can see that after i dismiss the first error about the device not working i get the standard save dialog box, if i click save it asks me if i want to overwrite the existing file, after accepting to overwrite then WriteAsync is called and i can update the file contents
I'm not quite sure why it would first tell me there's an error and then still allow me to write the file but only as replacement to the original file
Thanks for your help
Fixed, i found that there were issues with the ILockAsync implementation, reviewing the FileSystemStorage sample helped fix the issue with locking files before writing or updating properties
I've got an 'interactive PDF' that I need to be able to edit and save in an iOS app and I'm looking at how to achieve it. It's got text boxes and radio buttons which I can interact with in the UIDocumentInteractionController preview (or QLPreviewController) but there doesn't seem to be a way to save those changes to the file that was loaded and if I share the live and edited file to my mac via AirDrop it doesn't send the changes, rather it seems just the original file.
I don't really know anything about interactive PDFs so not sure how added text would normally be saved. I've found that the 'Files' app (added in iOS 11) actually saves the edits you make, so that's basically what I want to be able to do.
At the end of the day I just need a way to be able to interact with a PDF in my app and save the changes. Do I maybe need to use a custom PDF viewer rather than trying to piggy back off the standard iOS file previewer functionality?
Looks like this library solves my problem: https://github.com/derekblair/ILPDFKit
It lets you edit a PDF, access and set individual fields and save out as a static PDF.
I am using ZebraDesigner to create labels and save them as .zpl, files, then manually editing the zpl code to customize it further, and then save it in the printer's directory in onboard flash memory.
I see the .zpl files, listed with their sizes, in the flash directory, but the files are blank when opened, or sometimes contain text belonging to another file. If I try to paste new code into the file in flash, I'm unable to save it; meaning, I click save, and the web pages merely changes the file extension from ".zpl" to "---", then if I save again, then I get an error the script could not be saved.
I've been unable to get sufficient information nor resolution by contacting Zebra or looking at the product documentation. Advice would be appreciated.
I need to individualize documents within an iOS-App. I could provide the origin-documents as DOCX, PDF, PPT etc. The output-format has to be PDF.
My minimun requirement is to fill some text-fields. Nice to have would be to replace an image, too.
I´m quite used to generate PDFs programmatically using UIGraphicsBeginPDFContextToFile etc. But in my current case I don´t want to create the whole document programmatically, I just want to replace some content.
Any hints / tipps?
Thank you in advance.
DOCX is a zip - format file so you can process the contents programmatically and the reconstruct the zip file. PPT is a binary format though newer versions of PowerPoint might also construct zip-oriented versions that you can programmatically process. You mentioned though that you need don't want to programmatically process these documents - which I would probably also do only as a last resort.
For your DOCX origin/source documents (or doc,odt,rtf but not ppt/pdf) you could use Docmosis cloud services if your app can have the external dependency. You would upload your DOCX origin documents with placeholders for text-fields or images as a one-off/occasional task. Your iOS app then calls Docmosis sending instructions and data to create the output PDF and either stream it back to the app or email/store it or both.
The upside is it takes all the load and coding away from the iOS application (there is an SDK). The downside is it is an external depdendency. Please note I work for the company the created Docmosis.
Hope that helps.
Why not just load a page in a webView modal that points to a URL of a page you create? The main parts of the page would be static, and then the fields you need to customize would be populated via Javascript or PHP.
For example, we have a contact form in our app that gives you an option to view the details of your completed form after you submit. When the user clicks on the button to view the Contact Confirmation, it loads example.com/confirmation.php in a modal view within the iOS App.
On the confirmation.php page (on the web), I use PHP to pull in $_GET variables from the URL parameters which then populates the page with my static content, and their customized information that they entered into the form.
I am looking to be able to open a pdf file (done) and then be able to use the touch screen to sign the pdf and then save it with the modification. From what i have read this is no easy task, and i have no idea where to begin. Any of you know any tutorials or frameworks that will help me with this ?
Also if possible being able to modify fields of a pdf file, on the desktop the pdf can have fields you can click on then type in to fill out the form, without the need to ever print. If this is possible as well that would be perfect.
Thanks.
Maybe libHaru (http://libharu.org/wiki/Main_Page) does what you want, it's worth a try.
Does your starting point have to be a PDF? steipete's suggestion of using a system to create the PDF would work if your app workflow could create the PDF (sans signature) and display it, the user "signs" it in your app, and you create the PDF again this time with the signature embedded. It depends on whether this flow is an option for your app. Often it seems easier if you treat PDF as a final document and produce the PDF in it's final form each time (final meaning that you're not going to try modifying it).
