Thanks for the clarification.
But I couldn't figure out how this works -
MessageBox::Show("Contents", L"Title");
The character set I'm using for the project is Unicode.
You will notice that one parameter is with the 'L' prefix and the other is without it.
So I'm guessing that the unicode version of Show is used and the 'L' prefix is optional.

I have been away.
From what little I have seen you appear to be using VC++ 2005, which I do not have. Therefore I can not test if this would even compile on that version of the compiler.
The example you provided should generate errors, no matter what character set you are using. You can not mix Unicode and Multi-byte strings in a single function call, the function takes one or the other type, but not both.
The only way this could work is if the compiler converted one of the strings, which it should not be doing, or the library provided functions that take mixed string argument types, which I have never seen before. In both these cases, MS would be doing something it should not be doing.
Sorry I could not be of more help, all I know for sure is that the ‘L’ prefix is not optional and must be used to tell the compiler to convert the string to Unicode.
Good Luck!

Look for /stack option.
This question is not related to CLI, should have asked in VC++[^] forum.

write a program that reads in the average monthly rainfall for each month of the year and then reads in the actual monthly rainfall for each of the previous 12 months. the program then prints out a nicely formatted table showing the rainfall for each of the previous 12 months as well as how much above or below average the rainfall was for each month. the average monthly rainfall is given for the months january, february and so forth, in order. to obtain the actual rainfall for the previous 12 months, the program first asks what the current month is and then asks for the rainfall figures for the previous 12 months. the output should correctly label months

Come on !
Try some thing yourself, if needed help, then ask for it. Don't ask to write assignment for you.

Your homework is in C++/CLI ? Either way, we're not going to do it for you, but it seems likely that you've posted it in the wrong spot.
We are here to help, we are not here to do your work for you. Try to do your homework, find the right forum, and ask specific questions if you get stuck. Refer first to your textbooks, the fact is, your teacher will have given you everything you need to complete this assignment ( and if they have any idea, they will be watching these forums ).

Can anyone give me a link to sources on the web or hints on how to write a program the will add and option to program window that minimize it to system tray? I want to do something simular to http://www.actualtools.com/windowmenu/ but only I only want to add a button to all application windows that will allow me to minimize it to system tray. For instance, if I startup Outlook it will automatically have this "minimize to system tray" added button it. If I run any application it will automatically have this "minimize to system tray" button added to it.
Thanks,

Does that mean you're using VC2005, and if so, is it the express edition ( as that would mean you can't use MFC ).
Did any of the answers you got, help ?

Yes, I think that I can figure out from the information that I received.

I need to get a Log file, this code get four message{applcation,mueventlog, security, system} i would get a list of apllication log, thank you
array<eventlog^>^remoteEventLogs;
remoteEventLogs = EventLog::GetEventLogs( );
System::Collections::IEnumerator^ myEnum = remoteEventLogs->GetEnumerator();
while ( myEnum->MoveNext() )
{EventLog^ log = safe_cast<eventlog^>(myEnum->Current);
MessageBox::Show(log->Log);

Hi all,
I am thinking to create an application of Cryptography and steganography. Its quite interesting topic but i am not much familiar with the logic behind it. Is there any one who knows much about it and could guide me any good book for this or any code which could be of my help.
Thanks

Hi,
Regarding cryptography, it is a very big topic.
Regarding steganography, the concept is pretty simple to explain. But implementation can take that to any level from simple to complex.
The concept behind steganography is, we hide the data within another multimedia content, which doesnt show off the variation with this hidden message.
To make it clear, consider hiding a simple test message "Hello World" inside a 24-Bit Bitmap Image.
A bitmap image contains, 3 portions(file header, bitmap header and the actual 24bit bitmap content). The 3rd part, the bitmap content, contains 3 bytes for each pixel in a image. Let us say we have a picture of size 5 X 5. This will have 25 pixels and hence 75(25 X 3) bytes.
The change in the Bit 1(Least Significant Bit), wont create much variation to the bitmap image. So we take this as the slot to hide our data. We split our data to hide into bits and store each bit in the LSB of the Bitmap data.
I have implemented a simple version of hiding the data using this concept. And also the data retrieval part in C++. It was a very interesting stuff to implement.
Thanks.

Thanks for giving the info..
I want to create application supporting Jpeg and.mp3 as my project. Well could you guide me the right path to follow so that i could achieve that in 5 months time.
I am not a really good programmer at the moment but i am working hard for that. I cant do anything simpler than this. like not bitmaps or .wav . I have heard its bit easy as its losless where as .jpeg and .mp3 are not.
Is there any particular bok for Stego and Crypto with C++ from where i can gain information.
Thanks a lot.

As far as i know, it is not possible to use JPEG for steganography. The reason is JPEG is a compressed form of a Bitmap and when we change the data present in JPEG, the reverse conversion(i.e JPEG to Bitmap) will be affected very much. That is the reason, we choose bitmap to hide the data.
Further, i am not much aware of the audio multimedia types. But i can refer to that and get back on that.
Well i could guide u on ur implementation of this module.
Thanks.

I think its possible with .jpg as i could find many articles after googling it.
But i have to prepare my grounding before i start anything.
Your help would be greatly appreciated. I was just wondering if there are any books for stego n crypto with C++ so that i could understand what exactly is going at the background.
And how complicated do you think it would be. I dont want that after 2-3 months i feel that i picked up a wrong topic. Do you think Stego is more difficult or creating a game engine.
But first i think i would go for bitmap and .wav, after achieving that i can step further. So what would you suggest, from where should i start my work on it.
Thanks a lot...

Please do not back out from this project. This is an excellent project. An excellent idea too. You have done a great job in choosing this.
About steganography books, i havent used any specific books just googled and got some info and applied the same. With steganography, there is nothing much to learn, we are going to hide the data, in some multimedia data. Just we need to learn the format of multimedia contents(image, audio). That i guess is easy to get from google.
And steganography is very easy to implement too. It took hardly 4 hours for me to implement that as a simple c code. Might be to put that in a GUI application it will take hardly 10 hours to implement.
So to start with you can read the Format of different multimedia types (Bitmap, WAV, etc). Then it is just a matter of finding least significant data portion in this multimedia contents, which can be used to hide our data.
So all the best in your effort. Please feel free to mail, if u need futher info.
Thanks.

Thanks for encouraging me.
I think ill start up with this project. I am just revising C++ as i left C++ few months back. So within 10-12days i should get onto proper work for it.
Please provide me with your email id or mail me at anantnigam@hotmail.com so that i could be in your contact throughout this project and would take your guidance...
Thanks a lot
