sorry, i didn't see where you mentioned plugging anything into the sound card... i thought you were doing it by ear.

Google ( with "open source guitar tuner" ) returned one hit on sourceforge.
I assume that for a software solution to work you will need a good microphone and a good soundcard to convert to a good useable frequence.

If you have a good enough ear to tune a piano then all you need to do is tune an octave somewhere in the middle (and a guitar tuner could help with that) and then tune the other octaves from that. If your ear isn't good enough to do that then your results would be pretty poor anyway, even if you can get the frequencies correct. There's a lot more to piano tuning than just getting a string to sound the right frequency.

Is it possible to Pass a 2dimension array to a function without specifying number of elements..
Thanks in advance

Of course: you can pass the address of that array. The question is what can do the function with an array of unknown sizes?

if it is a C matrix, then no, the function has no other way to know the number of elements but by getting it as a parameter. wonder what can happen if the function read/writes outside the actual bounds of the array ?
but you can construct a matrix class, or a std::vector<std::vector<type>>

The easiest way is to pass a vector of vectors, it will know it's size.

Anythings possible.
I suggest 2 ways:
First, how about putting the size in the first element? Cheating I know.
Second, put a terminator value in the last element which is used, similar to the \0 terminator in a string in C. But then you have to know some value which will never be used in the array. For example, if the 2-D array is 16-bit signed integers representing ground altitude in feet, use 32767 since Everset is ?? 29000 feet.

Hi,
I want to seperate some flash player functionalities as a seperate dll,so I want to make loadmovie function in that,
void Loadmovie(const char* url,bool IsMBCS)
url->Path of the movie
IsMBCS->to check coding(multibyte or unicode)
it in turn calls many functions,
Now i have to write c++ function to load a movie specified in the load movie function,what can i do???

A CFormView is a CView which lives within the realm of a CFrameWnd, not a tab control.

Hi all,
I am making one win32 client-server application using VC++.NET 2003. I am using NetworkStream->Write() function to send data. Now I am new in C++ programming and I want to send some BYTE values using this function but I don’t know how can I make array of all BYTEs I have. I know I can make array of BYTE from string using Encoding::ASCII->GetBytes() function but I have raw BYTE data like 0x09, 0x31, 0x21 etc..
Thanks in advance,
Priyank

For instance
BYTE myByteArray[]={0x09, 0x31, 0x21};
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Thanks,
It works for
BYTE myByteArray[]={{0x09}, {0x31}, {0x21}};
but I want to use the same variable for many time. How can I enter new values after sometime?

No idea. But I wouldn't take it too seriously. The votes that other people gives you does not affect your status and IMHO is only used to reflect people's feelings about the topic.
Nice, if you get top votes, but no skin off your back if you don't.

Yeah, I should try to ignore it though it irritates a bit. It just says playful kids are around! Funny

I would guess it was because you didn't bother to look at the documentation before making your reply that questioned the relevance of a correct statement.

Anyone can vote as they please; they are free to vote you down for no other reason then that it amuses them to do so. I don't see what Chris can (or will be willing) to do about it; he's not about to turn the CodeProject into a dictatorship!

I'm using the win32 API, so I would like to be able to use the SendMessage Function to change the text in these two controls.
eg:
SendMessage(GetDlgItem(hDlg,IDC_TIMESLIDER),UDM_GETPOS,0,0);
*this code is for getting the position from a slider*
Anyone know where I can find the flag for changing text, or for that matter some decent documentation on this?

Hi,
WSAStartup
Have you linked the following lib file to your project:
Library Use -> Ws2_32.lib : Link WSAStartup[^]
_beginthread
Have you included the following header file to your project:
#include <process.h> /* _beginthread, _endthread */
Link _beginthread[^]
