As Richard said, we need a lot more information than this if you want us to help you. If you're getting wrong results, then you're doing it wrong. At the very least, we need to know what you did, otherwise there's no telling what is your problem.
Regarding the primes, you shouldn't be needing them once the private and public keys are generated. Encryption and decryption only need those keys, not the primes they are generated from. As a matter of fact, breaking the code requires finding these primes, so knowing them at the time of de- or encryption would entirely miss the point!
See RSA Algorithm (Wiki) for details.

Hello!
I'm working on an application similar to MS Word, but on a much smaller scale.
My problem is that I do not know how to open a file just like Word does.
Word does something like this: if you are already in Word and you opened a file already and then you open another one from the file menu, than a new application appears with this file opened, just like the first file. But this application does not open a new WINWORD.EXE app. No matter how many files you open there's still just one WINWORD.EXE.
So, I want to do exactly like this in my application, but I don't know how!
If Word does not open a new app with the opening of a new file, this means that somehow the new interface opened with the file is linked with the initial dlls or with the files that have been loaded in memory.
I don't have a clue how to do that.
I'm working in C++, Visual Studio 2005, MFC.
Anybody has any idea?
Thanks!

If you're using MFC, you can find an option in the project wizard called Multiple top-level documents under Application type.
If not, what you need to do is to create a new UI thread each time a new file is opened.

Sometimes, I add some resource(png, string, bmp) to use. But because of some reasons, these resources may get redundant. The project is so large, many people join the development. So, there are lots of redundant resources.
Now, we need to translate the language in resource into other languages. So, we have to delete all redundant resource to increase the efficency.
Besides, have to remove all unnecessary png, bmp and other resources to make the final setup.exe smaller.
Resource Symbol Editor of Visual Studio is hard to use, I can delete an item one time. I need to find another tool.
I'm wondering if there are some existing tools to help me to that. Anybody can help me?

None that I am aware of. This would not be easy to do as any such tool would need to analyse every file in the project to see if there were any references to the resources before deleting them.

Being a messy coder I run into this all the time.
I believe there were apps called “code beautifier” which did that or something similar, but I may be wrong.
I hope nobody will make a suggestion that “memory is cheap, don't worry about it”.

Code beautifiers, merely tidy up your source code. I don't believe they can tell you which of your files may no longer be needed. Why not just move all the resources away, try to build the project, and you will get a list of missing files.

Redundant or unreferenced? Unless VS messed up and assigned two separate resources the same ID, I'm not sure how code could know if a resource was redundant.

I am wondering if anyone could help me figure out a way to reliably play a sound using 'PlaySound' function and not interrupting other threads in an application.
I am currently playing a wav file loaded into a resource at a given point in time based on the events that happen in other threads in a real-time application. But whenever it plays, it is interrupting my other threads for a brief moment. Is there any other better way to do this?
Here is my command
PlaySound(MAKEINTRESOURCE(IDW_WAVE),AfxGetInstanceHandle(),SND_RESOURCE | SND_ASYNC);
The duration of the sound is less than a second.
thanks

The SND_ASYNC flag plays the sound without interrupting other threads.
How do you measure that the other threads are interrupted?
In which thread is the PlaySound function being called.
Some info about how the threads are arranged in the application would help for better diagnosis.

I am using SND_ASYNC mainly to achieve that. But it still interrupts other threads. I am playing it in a separate thread that runs parallel to other threads and runs upon receiving an event or else waits indefinitely for the event to occur.
I can tell that playing a sound effects other threads by looking at the frame that I grab continuously from a framegrabber, where I miss a part of the frame whenever I play the sound.
All my threads run parallel and all the threads wait for a certain event to occur. I start all the threads when I run the application, but keep them waiting for certain events to occur. While couple of threads run most of the time, some threads only run when they receive certain event.
thanks

Do you have a multi-core processor?

The standard MFC windows provide full scrolling capability. Your code just needs to set the window and view sizes to enable scrolling. Take a look at the CFormView class[^].

What do you mean by "develop window application project in asp.net"? The two are mutually exclusive.

There is no "best" choice, there are merely different solutions. The best one is the one that most closely offers a solution to your requirements: Win32, MFC, Windows Forms, WPF etc., it is up to you to decide which one to go with. However, you seem confused about the difference between desktop apps and web apps, so you should decide first which of those is necessary for you.

When lock the CriticalSection, the same thread can enter this CCriticalSection more than once at the same time.
How to avoid this problem?
