I am developing a QR code application. But I am interested that no one can scan my QR code except my application? Is it possible or not?

First sorry for my english, I'm a french guy so I don't speak it perfectly don't be to fierce with me ;)
Presently I'm working on a smartphone application developed with cordova, in this application we got the notion of order and I need to create a way for the user to download a PDF with his order details.
For the project, we are using an ASP API, so I think the best way to do it it's to ask to the API to do it for me but still that after some research I havn't find any clue to generate a PDF sendable to my application on the API. Or perhaps that I've miss understood some stuff, but I'm a little bit stuck currently ^^'
Have a good day!
If understood your question right, the easiest approach is to generate PDF file using server side coding and store it in server. You can then access the PDF file from server and store it in device using cordova file transfer and cordova file plugins.
I have created a program in Visual Studio 2013 using Visual Basic. This program allows the user to enter in certain criteria via controls then they click on a button and the program searches an excel document with several spreadsheets and returns the appropriate information to the user. The program runs perfectly as it was intended (thought a little slower than I would like). I have now been charged with making this program a web application.
I have done enough research and have settled on using ASP.NET and visual basic (If there are other suggestions I would welcome them). I have re-created the GUI in ASP.NET as best as I could and I'm now left with the extensive coding part. My first question is by turning this program into a web app can I still use Excel? How would that work on the server side instead of everything being on the client side. Is there a completely different route I should be thinking about to accomplish what I need.
My original program revolved around opening an Excel File, searching the various spreadsheets and returning data that fit the user's chosen criteria, how should I go about this with a web app written in ASP.NET and Visual Basic.
Thank you for any assistance anyone can provide.
hi i am new to video streaming. Is it possible to trace the timestamp of a particular advertisement fragment in live video streaming? Is there any tool to achieve it? If yes, how to integrate that tool with dot net application?
Can anyone suggest me anything to achieve it ASAP?
Detectors (analysis components) can be written in C++
You could detect commercials via few tools, but doesn't look simple.

To integrate it with .NET app, it depends on how the tool exposes its features, if you are lucky to get an API, wonderful. If its a console app, you could integrate it easily with C#.
I need a simple,small and efficient program for the following thing to do.
A small interface to choose a file from my PC.
Press encrypt/De-crypt button to do select whichever you need.
If encrypt is pressed, generate a random key and encrypt with some algorithm based on that key.
If decrypt is pressed decrypt the file using some algorithm.
I am planning to do it in visual C++. Can anyone please suggest a small program in VC++ to do this? or please tell me the library name where I can get all the functions to do the above.
If you think that there is some better language or framework available to do instead of VC++, please suggest. Thanks. I would very much grateful to you for this help.
Visually C++ can call clr code when compiled with these options. Once you have done that, you can use this api or the far more secure version that Microsoft published here. I'd use the second because then you get authenticated encryption for free. Otherwise you need to hmac the data and check it on the other end, which is a pain. In either case, make sure you use a random IV each time ( by default when you instantiate aes in .net , it creates a random IV so just use that). Prepend it to the message and retrieve it when you decrypt
I am wondering if there is any codes sample for ASP.NET with Voice recording.
Ok, Basically, i want to create a web page that allow user to click a record button and record his voice thru his/her microphone and then convert it into mp3 file, then i want to click PLAY button to play what was recorded.
I have searched google alot and cannot find any codes that code do just that.
I have seen site that can do just that and it is using FLASH with RoR (i think).
Is there any way to record voice using ASP.NET?
I dont care if it need to combine with FLASH with ASP.NET, as long as it is possible.
Thanks.
EDIT:
Stephen M. Redd,
Appreciate your input. Yes, i know there is no simple way to accomplish what i am asking for. I also have researched and google alot on this question. Yes,I have come to know the best way to do this is through using FLASH with either FMS or RED5 (open source).
So i am trying to figure out how to write a simple FLASH (.swf) that i can record voice and then save into mp3 format to RED5 server.
Do you know or can you provide any directions to what i am asking above?
1) Tutorial on Microphone class in FLASH (i am reading some basic implementation from a book called "FLASH Actionscript in a classroom", which doesnt tell me how to record voice but ONLY how to use microphone object in FLASH)
2) Tutorial on how to setup and use RED5 (FMS is NOT an option due to its cost)
3) how to integrate 1) and 2) with asp.net and javascript (if there is any flashvars that the FLASH microphon .swf i can access so that ASP.NET can be used with javascript)
Thanks.
EDIT 2:
I cant consider to accept an answer BECAUSE none of them has provided a good answer.
Take a look on my question and read the comments i got, and you will see that my question was NOT being provided a good answer.
My question is to find a web-based Audio/Voice recorder so that the users can record their voice on the site.
To better convey what i exactly asked for, take a look at www.snapvine.com or www.pubclip.com . Both of them provide a way for users to record their voice right on the webpage.
So, i am looking for a FLASH component (.swf) similar to what they offer to integrate with my site.
EDIT 3:
This voice/microphone recording thing seem to be a challenging project for most developers.
I guess this means i am all alone.
I think this is something that would have to be done with Flash.
This guy appears to have some examples of doing voice recording in Flash, with code samples:

There is no simple way to do this kind of thing. Standard web technologies based on HTTP and HTML just don't have the features. HTTP doesn't work well with moving audio data, and HTML and Javascript are not able to talk directly to the hosting OS or hardware resources like the microphone.
There are 3rd party browser plug-ins and applets that you may be able to use via a web application to do this kind of thing.
Most people use Flash and the Flash Media Server to do audio input via the web.
There are also some Java applets that have similar capabilities such as the ListenUp SDK (I have not used this, so it isn't an endorsement).
There is a lot of discussion on this topic related to Microsoft Silverlight, but as I understand it voice and camera inputs from the client side are not supported as of Silverlight 2, though it may get put into Silverlight 3. There is a good bit of information about how to use the necessary Flash bits within a Silverlight application though. For more info on that, check out this post.
ASP.net is a Server-Side Technology, but voice recording is done Client side. So regardless if you use ASP.net, PHP, Ruby on Rails or Cobol, you can't do it directly.
What you need is a Client-Side Application that works together with the Server Side to accomplish this. I do not know if Silverlight can do Microphone recording, but Flash can. This is apparently quite easy using the Flash Media Interactive Server, but normally you should be able to do this without, i.e. just by having a Flash Application doing the recording and then Uploading it to the server.
Hi Sam in Silverlight 4 it is possible to record voice from microphone and webcams.
Just follow the blog.
