If you remove them, do the linker errors persist?

looks like you're missing the implementation for the F2X, BigInt and Point classes (and maybe others). do you have the files where those classes live ?

if these classes are part of an external library, make sure the appropriate .lib files are listed in your Imports.

If I remove these two functions i.e
use_NIST_B_163 ();
EC_Domain_Parameters dp = NIST_B_163;
I dont get any link errors.
another thing is that the library Im using doent have any .lib file
u can find the library here
"http://dragongate-technologies.com/products.html#borZoi"
plz help me.

You're right there's no .lib file in the zip download. You have to include the source files in your project. From the manual: There's "Microsoft Visual C++: Add the ”borZoi.dsp” project file to your project’s workspace and add the header file directory to your project’s include files path." In my VC++6.0 this is done by "Project->Insert project into workspace..." Did you do this? You will include the source files (.cpp) in your project, and you should be able to see the classes in the class pane of VS. Remember to add the header file directory as well.
I guess that the reason why you only see the linker errors after adding your to lines of code is that this is the only point in your app where you call use_NIST_B_163(), and hence this line makes the linker look for all the symbols that use_NIST_B_163() depends on.

You can just click the email button on my reply. I'll gladly look your project over, but I only have VC++6.0, so if you use VC.NET I can't help you.

ok, this is what it looks like to me:
This is a solution that you need to load with Visual Studio and compile/link. When you do that it produces a static link library (the .lib file) which you then include to your imports.

For example, i want to get the virtual-key code value of the char ':'.
How can i get the value?
I love you not for whom you are, but who i am when I'm by your side

Handle WM_CHAR message , It nChar argument contain the value for each key.
BTW Virtual keycode for ':' is undefined and it is equal to 3A(HEX) or 58(DEC)

Hello,
I don't think that there is an easy way to do it, but you can always use a map:
<list> Create a separate module create a private map that on initialization maps all virtual key codes to their ASCII (or UNICODE) counterparts.
Create a routine that returns the key code for the character passed to it.
Example:
#include <map>
static std::map<TCHAR, UINT> g_KeyCodeMap;
static bool g_bInitialized = false;
static void InitializeKeyCodeMap()
{
g_KeyCodeMap.insert(std::make_pair(_T(SomeChar), VK_SomeChar));
g_bInitialized = true;
}
int CharacterToVKCode(TCHAR Char)
{
if( !g_bInitialized )
InitializeKeyCodeMap();
std::map<UINT, TCHAR>::const_iterator ci = g_KeyCodeMap.find(Char);
if( ci == g_KeyCodeMap.end() )
return -1;
return c_i.second;
}
If I remember correctly, the VK_CODES in ASCII builds is the ASCII code of the character. So the VK code for ':' is static_cast<int>(':');. I could be wrong about this though.

I had a line of code:
void CProtocolSimulatorDlg::OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
It have error tell me that 'OnBtnsend' : overloaded member function 'void (bool,char [],char [],char [])' not found in 'CProtocolSimulatorDlg'
I do not how to solve it, can somebody help me...........

I suspect this means that this function is not defined in your header file. Why are you passing char arrays around ?

I think I do wrongly already. If I got a code below:
void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
{
int _PortNo;
if(condition1)
{
_PortNo=atoi(PortNo);
SOCKET CliSocket;
SOCKADDR_IN ServAddr; // used to specify a local or remote endpoint address to which to connect a socket.
WSADATA wsaData; // Create a WSADATA object called wsaData
WORD wError; // error flag
WORD wVersionRequested; //[in] Highest version of Windows Sockets SPI support that the caller can use.
int nBytesSent, nError;
wVersionRequested=MAKEWORD(1,1); // makes a request for the version of Winsock on the system
wError=WSAStartup(wVersionRequested, &wsaData);
if(wError !=0)
{
AfxMessageBox("Windows Socket Error");
condition1=FALSE;
}
else if(LOBYTE(wsaData.wVersion)!=LOBYTE(wVersionRequested)||HIBYTE(wsaData.wVersion)!=HIBYTE(wVersionRequested))
{
AfxMessageBox("Socket Version Not Correct");
WSACleanup(); // reset
condition1=FALSE;
}
else
{
CliSocket=socket(AF_INET, SOCK_STREAM,0);
if(CliSocket==INVALID_SOCKET)
{
WSACleanup();
AfxMessageBox("Cannot Initialize Windows Socket");
condition1=FALSE;
}
else
{
ServAddr.sin_family=AF_INET;
ServAddr.sin_port=htons(_PortNo);// takes a 16-bit number in host byte order and returns a 16-bit number in network byte order
ServAddr.sin_addr.s_addr=inet_addr(IPAddr);
nError=connect(CliSocket,(LPSOCKADDR)&ServAddr,sizeof(ServAddr)); // gives the amount of storage
if(nError==SOCKET_ERROR)
{
closesocket(CliSocket);
WSACleanup();
AfxMessageBox("Cannot Connect to Display Server");
return;
}
nBytesSent=send(CliSocket, Data, lstrlen/*returns the length in bytes */(Data),0);
if (nBytesSent==SOCKET_ERROR)
{
closesocket(CliSocket);
WSACleanup();
AfxMessageBox("Send Error");
return;
}
else
{
closesocket(CliSocket);
WSACleanup();
}
}
}
}
}
Where should I write it if I design a dialog that have edit box to type message and a button to send the message?

In your header file:
void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]);
in your .cpp file
void MyDialog::void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
{
//etc
}

Why don't you just take a number here ? Taking a char [] is a pretty ugly solution, even a char * is better IMO, but a std::string is the best non int solution, IMO.

You mean I write the code in the header file? Or in eg:ProtocolSimulatorDlg.h or ProtocolSimulator.h? And the .cpp file also same as what I want to ask....
|
|
|
|
|
You've never added a method before ? You add the declaration in the .h ( that is, just the method signature, no code ), and the full code in the .cpp file.

the declaration of the
void CProtocolSimulatorDlg::OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]) is missing in .h file
|
|
|
|
|
It seems that this declaration got deleted accidentally.
Just declare it in the header:
void OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]);
this is this.
