Working with Rexec

hi,
I'm working with Rexec in visual C++. I don't know any C++ so the going is slow. My task was to change the service, edit security so only certain ip's could remote execute. I succeded but, it only works in the debug mode used when -d is passed instead of -i and then allowing it to interact with the desktop. So when running as a Service it no longer does anything. I open a file and read data from it for the security addition and i'm wondering if that is the reason it doesn't work. can services do file manipulation? Any help is much appreciated, advice also welcomed because i'm a newb.

here is the code i added, it shouldn't have an affect anywhere else:
CAsyncSocket SrvSock;
SrvSock.Create(9987);
SrvSock.Listen();
CAsyncSocket CliSock;
// struct sockaddr addr;
struct sockaddr_in from;

//putting all hosts.txt values in an array for faster more effecient check

int count = 0;
int i = 0;
string ip;
string ipArray[MAX_IP];
ifstream openFile("hosts.txt");
while(openFile.peek() != EOF)
{
openFile >> ip;
openFile.ignore(255, '\n');
ipArray[count] = ip;
count++;
}
printf("array initialized with %d values\n", count);
openFile.close();

int nSize = sizeof(SOCKADDR);
// Loop to maintain the search while the application is running.
while (!m_pStop->Lock(0))
{
// Check to see if a connection is being attempted.
if(SrvSock.Accept(CliSock, (struct sockaddr*)&from, &nSize))
{

printf("Remote Address %s \n", inet_ntoa(from.sin_addr));//andrew: to print ip

SOCKET hSock = CliSock.m_hSocket;
CliSock.Detach();

while(ip != "")
{
ip = ipArray[i];

if(inet_ntoa(from.sin_addr) == ip) //.compare(ip) == 0)
{
printf("MATCH Verified\nACCESS GRANTED!\n\n");
//Let a seperate thread handle the individual connections:
AfxBeginThread(ProcConnectionFunc, (LPVOID)hSock);
i = 0;
break;
}
if(ipArray[i+1] == "")
{
printf("Verification Failed\nACCESS DENIED!\n");
ip = "";
i = 0;
}
i++;
}
ip = " ";

// openFile.close();
}
Sleep(1);
}
// Clean up...
SrvSock.Close();
}

I would try reposting this in the c++ forum, this isnt really the correct place for those types of questions.

I was wondering if anyone knew, is there something preventing a person from getting MCAD, and then taking the additional test(s)necessary to get MCSD?

In other words, can I take the tests required to get MCAD and then apply those tests towards getting MCSD?

Still coaxing software out of the can after all these years...

Actually that is what you do. I have my MCAD now and I am one exam from getting my MCSD (.Net).

Hey Steve,

I passed exam 70-316 a couple of weeks ago, and im preparing to take exam 70-315. There seems to be alot of shared knowledge between the two exams. Are there alot of html based exam questions for 70-315? Just curious,

Thanks,
Ryan

There is alot of shared knowledge, you are right. But you have to think about things from the web forms point of view not the windows forms. So there are some differences too. There should be quite abit of database info there, but that is on 316 too. Maybe abit more on 315. Of course there are questions on configuring the web application (web.config). Also know your debugging.

Of course all of this is info that you can find in the MS page on the exam, but I am just re-affirming what is there.

Thanks Steve, The reason I am curious is because of the ability to do many different functions in code-behind files vs. just editing the html of an asmx. I'm not a huge html guy, but I do often use code behind files with asp.net apps, so I was hoping there would be very little html.

Thanks again!

As I remember there should not be too much direct html on it.

Thats a relief because i'm taking the same exam in 2 weeks. However i don't get to do any web development at work, it's all windows based stuff, the only things i know about web dev is through reading the books for the exams and doing transcenders.

But the one that will really cause me trouble is the XML web services one, not looking forward to that at all! Frown | :-(

Anyone got any advice on specific areas that pop up in the XML web services exam?

Definately for any of the exams, have the environment installed and play with it. Do things that are not in the books. For web services, make a little calculator service and then write an app to use it or a word statistic service that takes a string and returns you teh word count, letter count, count for a given letter, the number of caps, the number of puncuation, etc. But you really should have some hands on experience with the things for the test. Learning for the books is good, but you have to use it to get the understanding of someone the things.

Of course for any of the exams, you have to know how to install and configure things. If you think about it, someone that has that certification should know how to deploy their app (win or web).

Debugging is also a big thing. On a windows app you can use message boxes and writing out to console windows and to debug files, but think about what you need to do from a web server perspective if the server is in a different state/country.

Database access (like for SQL Server) is also important, not only for the exams but for using it in real life too. Places that look at your cert will want to know that you can use their multi-cluster SQL Server with little effort.

Also http://transcender.com/ has free sample exams that are pretty good. I would download them and test your skills. Of course the free version is only 1 practice exam and the full cost one is something like 5, but practice is practice.
