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.

Should be:

{
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 
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.

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 ?

The random word generator you have used for this and your previous posts is working perfectly.

Hello,
I have an ActiveX control that provides such method:
void GetCurrentImage(long theFormat, VARIANT * theBuffer, long * theBufferSize)；
I want to get a byte image buffer from this function. That is, I am trying to do this:
long image_size;
VARIANT FrameBuf[1024*1024];
char ByteBuf[1024*1024];
pCtrl->GetCurrentImage(0, FrameBuf, &image_size);
I did some googling. But partly because VARIANT is a common word that confused Google, I can hardly find any useful solution to this. Can anyone give me some advice? Thank you very much.
Jason

Creating an array of Variant is wrong.
Try this
VARIANT FrameBuf;
BYTE ByteBuf[1024 * 1024];
FrameBuf.vt = VT_BYREF|VT_UI1;
FrameBuf.pbVal = ByteBuf;
pCtrl->GetCurrentImage(0, FrameBuf, ℑ_size);

_Superman_,
Thank you for your kindly reply. I guess you were meaning this, right?
pCtrl->GetCurrentImage(0, &FrameBuf, &size);
since GetCurrentImage() takes a VARIANT* argument.
But after I executed your example code(with GetCurrentImage line replaced with the above one) and checked the ByteBuf, I found its content is unchanged. Did I still miss anything here?
Thanks,
Jason

Please check the return value of GetCurrentImage to see if it has succeeded.

Unfortuenately, the function is an asyncrous function and returns immediatly, so return value is not useful. I have waited quite some time in the main thread and the check result is the same: the image size is returned correctly, but the buffer is unchanged...
