Hi
I will link an object of C module with a simple Win32 console application,
but became link errors. For example i have written a "void SomeFunc()" function in C module and declare it in testMain.cpp(Win32 API cpp module)as:
extern void SomeFunct(void);.
When i link this object, the result is:
1- SomeObject.obj : error LNK2005: _SomeFunc already defined in SomeObject.obj
2- testMain.obj : error LNK2001: unresolved external symbol "void __cdecl SomeFunc(void)" (?SomeFunc@@YAXXZ)
3- Debug/testMain.exe : fatal error LNK1120: 1 unresolved externals
Therefore, i try to declare it as:
extern "C" void SomeFunc(void);
When i link this object, the result is:
1- SomeObject.obj : error LNK2005: _SomeFunc already defined in SomeObject.obj
2- Debug/testMain.exe : fatal error LNK1169: one or more multiply defined symbols found
I don't know why? I will be thankful, when everybody can help me.
Best regards, Alireza

You seem to be including SomeObject.obj twice, most likely from diferent locations.

Hi,
maybe you could read forward and then turn your buffer...

Hi,
the most easiest way to do this is:
#include <string>
#include <algorithm>
using namespace std;
string buffer = "hello world";
reverse(buffer.begin(), buffer.end());

Hello All
Is there any command in SDK / MFC on passing the file name can execute with appropriate application.
For Example command ("a.wav") should open "a.wav" file in Real Player or what user has installed / configured to open the *.WAV files.
I can use, WinExec but it needs the executable path to be passed. User can install any type of player and configure different type of file format to open in different players.
One Clue is in the Command Prompt if we type the file name it automatically finds the application to be used and opens the file. If the file extension is not mapped with any applicaiton it automatically open the "Open With" dialog box.
So I there is any command which executes the string passed as in command line it will do.
Is There any command?
Thanks for your time
Ravi

Try it:
ShellExecute(NULL,"open","a.wav",NULL,"C:\\MyFolder",SW_SHOWNORMAL);
or
ShellExecute(NULL,"open","C:\\MyFolder\\a.wav",NULL,NULL,SW_SHOWNORMAL);

It is working fine... Thank you all...

My dialog have a button and I had edit the code like below:
typedef struct
{
SOCKET Skt;
SOCKADDR_IN AddrFrom;
int nAddrFromLen;
LPVOID ParamPointer;
}SOCKETDATA;
SOCKET ServerSkt;
void CTCPTestDlg::OnBtnstart(LPVOID lParam)
{
// TODO: Add your control notification handler code here
char szMessage[300];
wsprintf(szMessage, "(ListenThread) - Starting TCP/IP Initialisations.");
// WriteSysLog(szMessage);
ServerSkt = socket ( AF_INET, SOCK_STREAM, 0 );
if ( ServerSkt == INVALID_SOCKET )
{
//wsprintf(szMessage, "(ListenThread) - socket() Error. Unable to Create Server Socket.");
//WriteSysLog(szMessage);
printf("Error!");
}
else
{
SktAddr.sin_family=AF_INET;
SktAddr.sin_port=htons(ReadPortNo("[TCP.FLDATA.SRV.COMMUNICATION]"));
SktAddr.sin_addr.s_addr=htonl(INADDR_ANY);
if ( bind ( ServerSkt, ( LPSOCKADDR ) &SktAddr, sizeof ( SktAddr ) ) == SOCKET_ERROR )
{
//wsprintf(szMessage, "(ListenThread) - bind() Error. Server Socket Binding Failure.");
//WriteSysLog(szMessage);
printf("Error!");
}
else
{
wsprintf(szMessage, "(ListenThread) - TCP/IP Socket Binding Completed Successfully.");
WriteSysLog(szMessage);
if ( listen ( ServerSkt, SOMAXCONN ) == SOCKET_ERROR )
{
//wsprintf(szMessage, "(ListenThread) - listen() Error. Server Socket Unable to Listen for Connections.");
//WriteSysLog(szMessage);
printf("Error!");
}
else
{
wsprintf(szMessage, "(ListenThread) - TCP/IP Listening Stage Completed Successfully.");
WriteSysLog(szMessage);
hThread=AfxBeginThread (AcceptThread,lParam,THREAD_PRIORITY_NORMAL);
if ( hThread == NULL )
{
//wsprintf(szMessage, "(ListenThread) - AfxBeginThread() Error. Unable to Create AcceptThread() Thread.");
//WriteSysLog(szMessage);
printf("Error!");
}
else
{
wsprintf(szMessage, "(ListenThread) - AcceptThread() Thread Spinoff Completed Successfully.");
WriteSysLog(szMessage);
return 0;
}
}
}
}
return 0;
}
After I compile, it have 9 errors occur as below:
error C2146: syntax error : missing ';' before identifier 'Skt'
error C2501: 'SOCKET' : missing storage-class or type specifiers
error C2501: 'Skt' : missing storage-class or type specifiers

error C2501: 'SOCKET' : missing storage-class or type specifiers
fatal error C1004: unexpected end of file found
Error executing cl.exe.
I don't know how to solve it. Can somebody tell me

as it's already been said, you are missing a header file to include...
you must have a #include <> before using those types (they are declared somewhere ; C++ need those declarations before their use).
