i dont know. i want to this project but i dont know much about it. i come to know that socket programming will be used for this project. actually i am totally new to windows programming but i have to summit this project soon or i will in big trouble. i am trying my best to learn it but time is less, work is more. i will learn windows programming in detail after this project because then i will have more time.

It's not really an advanced topic as much as it is a specialized topic. See here for an idea.

thanks for the link. i have tried to write some code but it is not working. can u find the mistake i am making ? i want to find the status of the service "W3SVC", and when it is running, the program should print "Found" ---- #ifndef UNICODE #define UNICODE #endif #include <stdio.h> #include <assert.h> #include <windows.h> #include <lm.h> #include <tchar.h> #include <wchar.h> int wmain(int argc, wchar_t * argv[]) { LPSERVER_INFO_101 pBuf = NULL; LPSERVER_INFO_101 pTmpBuf; DWORD dwLevel = 101; DWORD dwPrefMaxLen = MAX_PREFERRED_LENGTH; DWORD dwEntriesRead = 0; DWORD dwTotalEntries = 0; DWORD dwTotalCount = 0; DWORD dwServerType = SV_TYPE_SERVER; // all servers DWORD dwResumeHandle = 0; NET_API_STATUS nStatus; LPTSTR pszServerName = NULL; LPTSTR pszDomainName = NULL; DWORD i; if (argc > 2) { fwprintf(stderr, L"Usage: %s [DomainName]\n", argv[0]); exit(1); } // The request is not for the primary domain. // if (argc == 2) pszDomainName = argv[1]; // // Call the NetServerEnum function to retrieve information // for all servers, specifying information level 101. // nStatus = NetServerEnum((LPCWSTR) pszServerName, dwLevel, (LPBYTE *) & pBuf, dwPrefMaxLen, &dwEntriesRead, &dwTotalEntries, dwServerType, (LPCWSTR) pszDomainName, &dwResumeHandle); // // If the call succeeds, // if ((nStatus == NERR_Success) || (nStatus == ERROR_MORE_DATA)) { if ((pTmpBuf = pBuf) != NULL) { // // Loop through the entries and // print the data for all server types. // for (i = 0; i < dwEntriesRead; i++) { assert(pTmpBuf != NULL); if (pTmpBuf == NULL) { fprintf(stderr, "An access violation has occurred\n"); break; } printf("\tPlatform: %d\n", pTmpBuf->sv101_platform_id); wprintf(L"\tName: %s\n", pTmpBuf->sv101_name); printf("\tVersion: %d.%d\n", pTmpBuf->sv101_version_major, pTmpBu

Should be:

if (QueryServiceStatus(hService, &ss) != FALSE)
{
if (ss.dwCurrentState == SERVICE_RUNNING || ss.dwCurrentState == SERVICE_START_PENDING)
printf("Found");
}

thanks, it is working now. i will bother u soon if i stuck in something. one more thing i want to ask. currently i have only one computer so no network. will this program work on a network of computers too ? i cant check myself. suppose i run it on a client, will it give the info of server or all the computers in the network (clients + servers) ? also, if i have the ip address of the server then how to use it in this program ? thanks again :thumbsup: rahul update : when i make a try to make a array of processes like this -------

wchar_t selPro[] = { _T("W3SVC"), _T("Iisadmin")};

SC_HANDLE hService = OpenService(hSCM, selPro[j], SERVICE_QUERY_STATUS);

where j is for "for" lool (0,1). when i compile this code, compiling completes without any error and when i try to run it, it crashes. if i pass without array, it works fine. please guide me

That's what NetServerEnum() is for.

First, did you try it? Second, did you check MSDN to see how OpenSCManager() handles its first argument?

Convert the IP address to the host name using gethostbyaddr().

Meaning what? A "crash" is fairly meaningless.

So where's the problem?

when i remove the following statements from the program, program run without any error.

NetApiBufferFree(ppTmpBuf);
NetApiBufferFree(pTmpBuf);

what may be the problem with this ?

It appears you are freeing the same memory three times.

yes, that may be the reason for the program crash. is there a way to access from a client if it have minimum access ? i mean that the client can access only a few folder in the other pc. also when i try this program on xp OS system, it gives the error --- NetQueryDisplayInformation gave error ERROR_ACCESS_DENIED. Due to this error, it does not display the status of service even of the system it is running on. it is a client pc. though i can ping the ip of other computers in the network. is there any remedy for this ?
