I am working as a Software developer for Mobile Applications. I am developing an application in which i want to retrieve the contents of the .doc files that arrive on the Blackberry mobile as an Email Attachment Part. Whenever i am retrieving the contents of the .txt files, the code written for the mobile is retrieving the accurate contents but in case of .doc files, it is displaying a lot of junk material in the header and footer of the actual contents.
So, my problem is that how can i get rid of this additional junk material as i want to retrieve only the actual contents of the .doc files. Please reply
Thanks
You can get the specifications of the doc-Format from Microsoft. Though, I don't know if they're complete or even useful. Another guess would be to have a look at Projects which have implemented it, like OpenOffice.org.

I checked previous questions here on SO but I think I want my functionality to work a little different. I understand that .tif files are not natively supported in Internet Explorer and that an extension, such as AlternaTIFF, are available to remedy this. However, I would like the dialog to show up where the user can either save/open the file on the client side. I know that MS Windows Picture and Fax Viewer can open them, no problems.
The files are located on our servers and this will be an intranet site. Currently, I have a link to the files populate in the view but again, I'd like that option for the user to Save/Open the file.
I'm using MVC, which I'm a little unfamiliar with, and can't seem to figure this one out. Thank you.
You can do an action that returns a tiff by changing the headers so when someone clicks the link the file will get downloaded or using FileResult.
Example with FileResult (i find it easier): http://www.dotnetcurry.com/ShowArticle.aspx?ID=807
For saving them is just like uploading any file with MVC. This post can be useful http://haacked.com/archive/2010/07/16/uploading-files-with-aspnetmvc.aspx
My advice is that you convert them to .jpg or .png when uploaded using GDI+.
//You first upload the tiff to the server like the post above explains
//And then open and convert it to .JPEG
Bitmap bm = Bitmap.FromFile("mypic.tiff");
bm.Save("mypic.jpg",ImageFormat.JPEG);
And if you already have the urls of all the tiffs, you can always do a console app to convert all of them. Even if you need to use tiffs its a good idea to have .jpg versions to show on the web. You can even resize them to create previews and save some bandwith too! :-)
Are there any good SDKs available on iOS that will not only display a PDF, but will show it as it is downloading from a web source? It is perfectly fine to use a paid for library as long as it is commercial-friendly.
To clarify, the SDK must be able to show partial files as they are downloading, whether I provide the stream or otherwise. I would like to avoid CGPDFScannerRef due to how low level it is -- I have tried FastPdfKit as well but it will only show the whole PDF after it has been fully downloaded. Any ideas?
PDF is a structured format that consists of different types of data blocks such as TOC, text, fonts, colors, annotations and information about these blocks is saved at the end of the file. So this makes it impossible for CGPDFDocumentRef to open the pdf without all the data available.
However you can get around this limitation by linearizing the PDF file so that the metadata information will be put at the beginning of the file. I'm not sure but I think you can then use CGDataProviderCreateSequential in combination with CGPDFDocumentRef to parse a partially downloaded PDF file.
I am a newbie in iPhone development. I am planning to do a PDF application for iPhone. The functionality is:
User will type their input in a text field (which is going to be the content of the PDF file).
I have to modify the PDF file through code while saving (paragraphs, tables, bullets etc).
User can save it in their own name.
User can send the PDF file as attachment of MFMailComposer.
So I have searched and got many links. However I didn't find any leading details to create and modify a PDF file in iPhone/iPad.
Can anyone please provide me a good reference to do this. Are there any alternatives to do this?
I've used this reference: https://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_pdf/dq_pdf.html
It contains theoretical explanations and source code examples

If you were doing a Phonegap app I'd say got for jsPDF, which would enable you to create (basic) PDF files in Javascript. I don't do Obj-C, but a quick look on SO provides good links.
I understand the basic of Document Interaction Programming and UIDocumentInteractionController and I've got it working in my app. However I'm having trouble with specific details of using custom file types. I can't find this addressed in the Apple docs anywhere.
My app uses it's own file types with unique extensions. The files themselves are just plists (xml), but I want the device to treat the files as only openable in my app. Originally I implemented the Document Interaction stuff to treat them as XML while I got it working, but now I want it to treat them as binary files that it needs to hand off to my app.
At the moment, if you have one of my files in an email attachment, iOS first shows the QuickLook (which just spews all the text content of the xml out) before you can choose to Open In. Similarly if one of my files is opened with Safari, Safari just shows the XML and doesn't give you the option to show it in my app at all.
So how do I get iOS to not treat my files as XML? I've changed the "Conforms to UTI" value and "public.mime-type" value in the info.plist, but it seems to have no effect.
Any tips greatly appreciated.
As far as i understand the UIT concept of Apple you cannot just change the file extension to change a potential UIT of the file. If the file contains XML-Data, other apps as well as internal apps might recognize your content and show it internally as XML.
Try to store your Plists with NSPropertyListSerialization NSPropertyListBinaryFormat_v1_0 (then you readble XML)
When you did that without success, why not trying this:
use zlib to compress the XML plists afterwards to a zipped file.
make a "unique" file extensions (<file>.myappname)
this should "hide" other apps and quick view.
Tell me if one of the ways did work for you.
Is it possible to search "words" in pdf files with delphi?
I have code with which I can search in many others files like (exe, dll, txt) but it doesn't work with pdf files.
It depends on the structure of the specific PDF.
If the pdf is made of images (scanned pages) then you have to OCR each image and build a full text index inside the PDF. (To see if its image based, open it with notepad and look for obj tags full of random chars). There are a few utilities and apps that do this kind of work for you, CVision PDF Compressor is one that I have used before.
If the pdf is a standard PDF, then you should be able to open it like any other text file and search for the words.
Here is page that will detail some of the structure of a PDF. This a SO post for the same.
The components/libraries mentioned in the answer to this question should do what you need.
I'm just working on a project that does this. The method I use is to convert the PDF file to plain text (with pdftotext.exe) and create an index on the resulting text. We do the same with word and other office files, works pretty good!
Searching directly into pdf files from Delphi (without external app) is more difficult I think. If you find anything, please update here as I would also be very interested in that!
One option I have used is to use Microsoft's ifilter technology, this is used by windows desktop search and many other products such as sharepoint and SQL server full-text search.
It supports almost any office/office-like file format, even dwg, msg, pdf, and files in zip/rar archives.
The easiest way to use it is to run FiltDump.exe on any files you have, and index the text output.
To know about the filters installed on your PC, you can use ifilter explorer.
Wikipedia has some links on its ifilters page.
Quick PDF Library's GetPageText function can give you the words from a PDF as well as the page number and the co-ordinates of those words - sometimes useful for highlighting.
PDF is not just a binary representation. Think of it as a tree of objects, where an object node has some metadata and some content information. Some of these objects have string data, some don't. Some of these are even encrypted, and some are compressed. So, there's very little chance your string finder will work on any arbitrary PDF.
