I am using HTML to PDF Converter in my Outsystems application, but when I open the downloaded PDF its size is zero bytes and I am not able to open the PDF too. It throws 'No registered application for this extension.'
Any hints ?
Have a look at that component's official discussion topic here
http://www.outsystems.com/NetworkForums/ViewTopic.aspx?TopicId=7393&Topic=[[]Html-to-PDF-Converter]-Discussion
Halfway through the (rather lenghty) topic a few people reported the same problem. It can be due to a multitude of problems from the page having runtime content (e.g. Flash) to write access restrictions for the creation of temp files.

It's quite possible you are missing some dlls. Remember to upload all the dlls in the zip file which you can install from here: http://wkhtmltopdf.org/downloads.html

I am implementing an application which its main idea is reading books using it.
the pdf files are on my server and I want the user to read the book without saving it on their device.
I thought about streaming the pdf file or embedding it. but it has some difficulties.
So, what is the best solution for this issue?
I am using Django-Rest-framework and Flutter
i think you have to use list of this packages for reading pdf files into flutter.

I need to download an archived google group.
Following link is one of the messages of that group for example.
https://groups.google.com/forum/#!topic/sci.aeronautics/ViFtpXfVm7M
The problem is, what i see in the browser does not appear in the downloaded webpage.
With my very limited knowledge, It seems to me like the reason behind it is this content is dynamically created by java-script. Or else, these downloaded files are with so called 'mbox' extension which is encrypted ?
What I've tried so far
First trys
Simple download
wget https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
With mirror
wget --mirror https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
Assuming its encrypted
With cookies.
wget --load-cookies=cookies.txt https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
Got thunderbird to setup my gmail and opening. did not open correctly
Assuming the content was javascript generated
Downloaded using phantomJS
https://askubuntu.com/questions/411540/how-to-get-wget-to-download-exact-same-web-page-html-as-browser
Downloaded using phantomJS with a different script
https://gist.github.com/giocomai/247d54e097b5083e2451
Used scripts available from Github
https://github.com/henryk/gggd
https://github.com/icy/google-group-crawler
But none did not work so far.
Can anyone please shed some light on how to download this page with its message as a readable html or txt file ?
Cheers

You could use https://groups.google.com/forum/feed/sci.aeronautics/msgs/atom.xml?num=100 to get some of the posts - but it only gets roughly half the posts in this case.
And it has all the messages from all topics together.
View it in Firefox or Classic Opera to see directly in a more human-readable form.
But since you say you already got a file in standard mbox format, what exactly is wrong with it - did you attempt to import it into a locally installed email or newsclient ? (like Thunderbird)
We are writing some program to display documents on iOS. I think that there are a lot of confusion on the web about what type of documents which iOS UIWebView could display. Generally people refer to Technical Q&A QA1630 Using UIWebView to display select document types to see that all the MS office 07+ files (such as docx, xlsx, pptx) could not be displayed, however actually that is not what we see from testing. Actually we are able to display docx/xlsx/pptx document at UIWebView either loading from a remote URL, local file or in memory (loadData, here the baseURL can not be nil on simulator, see this link). Of course We are testing on latest version of iOS on iPhone simulator, it might be that the support was not at older iOS. At this point, We don't know that yet. If you know, please let me know.
However right now, We have one issue to display document at UIWebView by using custom URL for security reason. I did the custom URL by following the code here: protecting iOS resource. We could display xls, doc, ppt, pdf file, but not docx/xlsx/pptx, We got some error like this:
EXCEPTION SFUZipEndOfCentralDirectoryError: Could not find the end of central directory record
We tried to debug and could not figure what's to do here. Do you see similar error here? Could anyone shed some lights on this? Thanks very much.
It looks like the document you're trying to open might be corrupt. docx, xlsx, and pptx files are actually zip files containing a bunch of XML documents and other data. Check if you are able to uncompress the file on your computer by renaming it to .zip and then unzipping.
I'm working on a mobile site for the iphone. I've added a cache manifest and loaded it with a list of resources needed for offline capability. The manifest file has the correct content type. You can view the manifest file in the header of this page:
http://www.rvddps.com/apps/sixshot/booking.html
I had a bunch of links to pages but due to my user level i'm only allowed to post one link. You can see the manifest file there and the source code of the page i'm trying to cache.
I've set the correct MIME type on the server, but the cache only seems to work occasionally.. not all the time. I've tried following apples' official caching guidelines as well.
Can anyone point out where i'm going wrong?
Thanks
Daniel
I looked at the manifest file and found 'Â' characters in some of the blank lines. What text editor are you using? Make sure you use the proper encoding and line ending types.
I suppose office files(prior MS office 2007) cannot be accessed using open xml sdk2.0 or if they cannot be programmatically accessed using the open xml format.
so is there any way to work or these older version files or can i view the xml content of these files.
or is it that open xml sdk isnt designed for that purpose
See the answer to a similar question I asked when I just started learning this SDK.
No but the open source project POI provides an API to most of the old formats. Warning POI is a bit (not a lot) buggy, does not fully implement the specs, and support is catch as catch can (ie it's open source).
You can use Office File converters to convert to open xml formats and start processing it.
See here:

I'm using this for my application. This works for me.
Hope this helps.
