Hello all I am making a client server application in which client will call system calls and send the information to server. I want to store that information into database e.g Access using ADO( in VC++). Plz guide me what should i do? Do i have to do serialization of data? e.g From client i have to send the the computer name and user name to server. how will i do this ? how will i serialize data? how will i use ADO? I am newbie plz be aptient with me and also tell me examples as well Thanks a lot

I am building a client server user tracking system that will get the username and computer name from the client kernel and send it to server via winsock. I have got the different pieces of the puzzle but now i want to combine them all. So help me out 1) i have the perfect running code of the system call GetComputerName( ). which uses windows.h #include #include int WINAPI WinMain(HINSTANCE h,HINSTANCE p,LPSTR c,int n) { TCHAR szName[256]; // pointer to system information string TCHAR szBuffer[512]; // buffer for expanded string unsigned long iTextLength; TCHAR szSystemInfo[5]; iTextLength = sizeof(szName)/sizeof(TCHAR); // number of characters, not bytes GetComputerName(szName, &iTextLength); iTextLength = sprintf(szBuffer, "Computer name: %s", szName); MessageBox(0, szBuffer, "Computer Name", 0); GetUserName(szName,&iTextLength);//Get User Name iTextLength = sprintf(szBuffer, "User name: %s", szName); MessageBox(0, szBuffer, "User Name", 0); return 0; } 2) I also have the perfect running code of client which uses MFC and sends the status of the client-- that is sends the string from the client which is received at the server. #include "stdafx.h" #include "client.h" #include windows.h #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // The one and only application object UINT sendStatus(); CWinApp theApp; using namespace std; int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) { int nRetCode = 0; sendStatus(); return nRetCode; } UINT sendStatus() { SOCKET client; WSADATA wsaData; //data structure sockaddr_in serveraddr; //sockaddr_in int wsaret=WSAStartup(0x101,&wsaData); //Initialize wsaret variable if(wsaret!=0) { cout<<"Fail to initialize:"; return 0; } struct hostent *hp; unsigned int addr; struct sockaddr_in server; CString servername="localhost"; SOCKET conn; conn=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); if(conn==INVALID_SOCKET) return 0; if(inet_addr(servername)==INADDR_NONE) { hp=gethostbyname(servername); } else { addr=inet_addr(servername); hp=gethostbyaddr((char*)&addr,sizeof(addr),AF_INET); } if(hp==NULL) { cout<<"Fail to get peer address:"; closesocket(conn); return 0; } server.sin_addr.s_addr=*((unsigned long*)hp->h_addr); serve

DOes anyone of you know about the C++ bulider and its Client server Suit. I have got C++ builder 1997 edition but there is no serversocket and clientsocket item in the internet component tool kit. Plz help me out from where to download them ? or from where to activate them?

Hello i am using windows XP as administrator. The problem is that the exploerer does not save the pages offline. That is you can view them offline.

Is there any way the exploer behave as in windows 98 and 2000 where u can see previous webpages by going to histroy . Is there some problem with installation? Plz help me out

I am making a client server application which for network monitoring in wwhich client will run as NT service. Now i am really in a fix should i do the project in MFC or C++ builder? In case of MFC What are the MFC 's classes and objects which encapsulates "GetUserName()","GetComputerName()","EnumProcess()" and "SetDiCreateDeviceList()" for device lists. Do u thinks C++ Builder's RAD environment will help in making the project faster? How different and difficult is it form Visual C++? Thanks

1)I converted the MFC TCP server into non mfc TCP server using winsock.h. It complies and runs but it does not performs efficiently as the server thread is not created properly in the non mfc statment of _beginthread and CreateThread Plz modify the code so that it runs smoothly thanks 2) what i have to do to make UDP server? 3) how can i change it into mutithreaded server( that accpets connections from many threads?) #include process.h #include windows.h #include iostream.h #include conio.h #include winsock2.h /* _beginthread, _endthread */ #include stddef.h #include stdlib.h unsigned int ServerThread(LPVOID pParam); int main(int argc, char* argv[]) { HANDLE hThread; unsigned long iID; cout<<"!!hello world!!\n"; LPVOID var=0; //unsigned int block=0; //block=ServerThread(var); //Call to the function // _beginthreadex( ServerThread, 0, NULL ); hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE )ServerThread,NULL,0,&iID); //_beginthread(ServerThread, 0, NULL ); // hThread = (HANDLE)_beginthreadex( NULL, 0, &ServerThread, NULL, 0, // &iID ); cout<<"\n\nyahoo"; // while(getch()!=27); // getch(); return 0; } unsigned int ServerThread(LPVOID pParam) { cout<<"Hello from thread"; SOCKET server; //Socket is unsigned int WSADATA wsaData; sockaddr_in local; // Structure variable int wsaret=WSAStartup(0x101,&wsaData); //Initialization if(wsaret!=0) { return 0; }

Hello, i am trying to build i client server application using winsock library but i thinkit will be easy by not using MFC. Please give me tutorial about how to make a simple client and simple server. At the client end i will be using GETCOmPuterNAme() and Username apis and i want to transmit them to server. Please help me out in this regard.

i included the windows.h,setupapi.h,stdio.h i want the computer to enumerate the hardware devices like mouse,key board, NIC etc.... thanks

Do you know of any such api or function which enlists applications? eg, Internet explorer,Word,Power point etc. Also do you know of any api which enlists the the hardware devices like mouse,keyboard,NIC etc Please tell about these apis and their header files Thanks a lot

it uses windows.h and stdio.h headers
