I am working on a image processing project. I am not familiar with html. Here is what I think.
My C++ application is able to read an image and write the image to file after processing. The procedural is that user can click mouse in a fixed region of my web, and the position data could be passed as parameter to my application, and then my C++ application will use the position data to process the image and output image to file, finally my web display the image.
So is that possible to implement this?
I'm afraid it's not possible only with HTML.
It should be possible with any server-side scripts written in PHP (for example). Anyway, you can make you program to watch folder uploaded and processed images save into another folder. You will need PHP or something like this though.

I implemented a PDF Viewing widget in C++ using Qt, loosely based on https://doc.qt.io/qt-5/qtpdf-pdfviewer-example.html, using the pdfwidgets module. (For this question, we can assume that I copied the code in that link 1:1).
This works well so far.
But now the thing is, the PDF I want to display happens to be an animated PDF. Opened in a regular viewer like Acrobat, it will show a short sequence. That sequence is located on a single page, the frames are not different slides.
In the documentation of the QPdfDocument and the QPdfPageNavigation classes, I can't find any functionality that deals with animated pages. It would suffice if I had any way to set the current animation phase.
Is this possible at all? If so, how?
It's not implemented at the moment. On Windows, you could use an ActiveQt widget to embed Acrobat Reader inside your application, if present. Otherwise you'd need to find a PDF rendering library - most likely a commercial one - that has such support.
I have an application that relies on many images. I have no problem loading the images on to the window. I would like to make my application have the images integrated into it where there are no actual image files in the folder. Also, I would like to know how to do this, because if I sell the application I don't want the user to be able to go to the directory my .exe is located in an get the image file (I am aware that they can print screen it). So, how can I integrate the image into my application. I am using the WinAPI with C++.
I have searched this multiple times and have not found anything on this. I have found one question on another forum, but it was asked a long time ago and was not answered. I did find one other place that had this, but It did not specifically work with my question.
You can bind images (as well as pretty much any pieces of data) as resources to your binary.
As part of my application, my client has requested that I include an automated e-mailing system. As part of this system, I generate HTML code and use automation to send it via. Outlook.
However, they also require a PDF copy of the HTML document to be sent as an attachment. My initial attempts involved using libHaru, which proved difficult to use efficiently, as I was required to create the PDF document from scratch, which required computation of the position of each of the lines in a table, and positioning of all the text, etc.
I was wondering if there would be a way to programmatically convert HTML code (or an HTML file if need be) into a PDF document either by using Win32/MFC itself or an external library.
Thanks in advance!
EDIT: Just to clarify, I am looking for solutions which minimize external dependencies.
You should evaluate this utility wkhtmltopdf:
http://code.google.com/p/wkhtmltopdf/
You can call it from the command line without the need to run a setup.
I use it generating my output documents as html then cal a ShellExecute(...) to convert it to PDF. It's great!
Inside uses webkit + qt. So compability with modern HTML is OK.
Hope it helps.
I'd take a look at PDF Creator, which can be used as a COM object (that acts pretty much like a printer). I haven't used it to print HTML, so I'm not sure, but my guess is that you'll probably end up having to instantiate a web browser control to render the HTML, and then feed it from there to the PDF control.
Some possible answers are in this thread:
C++ Library to Convert HTML to PDF?
Not sure if they will satisfy your particular requirements, but these might at least get you started.
Edit:
Some other possible options here.
Not MFC but you can try QtWebKit. It can render and export HTML to PDF, PNG, JPEG
I am looking for a django app that can help smooth the process of uploading big size documents by using HTTP Post.
Documents ranging anything from 150mb to 500mb.
I wrote a small library that handles PDF uploads and parses it to my scribd library and through that embed it onto my site.
Currently my model is quite simple, it takes a FileField, preferably PDF and just and uploads the PDF File, through that makes use of the scribd library and send it directly to scribd for encoding.
The problem is, somewhere along the actual upload process, it times out, no errors in the log, I have adjusted my django apps size for files, Apache's size for files, and I am a bit lost at the moment not knowing where to go from here.
Although I want to eliminate the manual work, so ideally I'd still like to use it through my site.
Any help or pointers would be appreciated.
Probably a bit too late, but, have you tried django-bft
I need an animation in my program. My designer draws animation in Flash and provides me with *.fla file. All I need is to grab 30-40 PNGs from this file and store them within my internal storage.
Is it possible grab resources from *.fla with C++ ? Probably, some Adobe OLE objects can help?
Please, advice.
Thanks in advance.
If I asked an artist to make me an icon I wouldn't expect to need to write code to convert a .3DS model into a usable icon format.
You can save yourself a lot of time and hassle by having your designer use File->Export and give you PNGs of the layers and frames instead of a .FLA file if that's the format you require for your implementation.
If that's not possible for some reason then you can probably find a flash decompiler that has a command line option which you could launch from your program to extract assets as part of your loading sequence but that is generally frowned upon because this is not the intended use of the proprietary format for .swf/.fla anymore than you should design applications to extract source code from a binary executable.
Assuming
You are using CS5
The assets used internally in the FLA are already PNG's as you want them to be.
Then simply get the FLA saved as a XFL file, and you will be able to grab them from the library folder ( but then why not just get them to mail you the pngs ? )
So if for some reason you can only get access to the fla and not the designer, then you can do it programatically by renaming the fla to .zip, extracting.. and you have the XFL format.
