This is some linux/gcc -c code.
I have no idea how this is working and I can't test it. And, btw. I won't do your homework!
You need to ask specific questions, preferably in another thread, and with a meanigful headline. This way, all people who (unlike me) know about your subject feel invited to help you.
I hope I could help you at least a little.
Who is 'General Failure'? And why is he reading my harddisk?!?

void svc_crash(int) = 9 ;
void clnt_crash(void) = 10;
} = 1;
} = 0x30090949;
The first procedure is used to login as a user
The second is to connect to a server.
The third procedure is to view list of available messages.
The fourth procedure is for posting messages.
The fifth procedure is for deleting messages read or unread.
The sixth procedure is for reading messages.
The seventh procedure is to start the server.
The eighth procedure is to handle the expiration of messages.
The ninth procedure is to handle crashing server.
The tenth procedure is to handle crashing client.
4. Running the program
To start the server application, enter: mserver
To start a client application, enter: mrn [hostname]

Get a copy of the directshow SDK. I think that it is now part of the main DirectX SDK. Have a look at the AMCap sample application, should get you started.

Hi,
I'm having problems with the CMenu class and was hoping someone would be able to help. The problem is that the CMenu class is modal and therefore stops the rest of my application from running whenever a menu is opened. This is a problem because every program cycle I look at a comm port and read in whatever is in the port. If someone leaves the menu open the buffer fills up and I have to resynchronise with the external hardware. Is there a way to make the CMenu class act in a non-modal way or is there a way to handle the comm port (without using threads preferably)?
I'm using Visual Studio 6.0 and am using the MSComm ActiveX control to communicate with the comm port.
Thanks in advance,
Phil

The problem here is not the CMenu class. You have a classic problem of trying to do too much in the UI thread. You should be spawning a worker thread to deal with the communication port sending/receiving. This other thread can post events to the UI thread as they occur in the form of message, which will be processed in the UI thread even if a menu is open.
I do beleive that the serial port example(s) here at CP take this approach.

I was worried you'd say that... I think you're right. I've used the UI thread in the past for processing comms but never with the CMenu class as well. Never mind, rework here I come.
Thanks for the help.

You didn't say for what protocol, but if you are talking about HTTP, try looking at HKEY_CLASSES_ROOT\http\shell\open\command.

hi ,
does anyone has any idea about the conversion of .bmp/.jpg to .pcx format.
Any idea about any classes will also do
Thank you.

When the trial period of my app has expired (jtodaysdate - jinstalldate) plus some other things I better not mention here. Should I?
Write to the executable a bunch of 01010101010101
or set a GUID mutex atom to a instance of the os?

The best way to implement a trial period schema is to use some method that modifies the application executable itself. This way, a peep who'd want to hack your trial protection would need to have solid understanding of assembly and reverse-engineering.
Of course, the securest method would be a combination of executable modification, registry keys and INI/DLL-files.

OK Great,
I have lost faith in folks ability to be honest.
I posted my static ip on codeproject by accident in a response and have gotton 82 hack attempts so far, none got through.
Anyway I thank you and understand the reference to dll and ini and have implemented them.
I guess I will write 0's 1's to the executable also.
If I set the GUID of the mutex to the guid of the os and only allowed 1 instance that would be cool, also!
Great answer thank you!

Neither,
I would think you want to show nice dialog: "Trial period expired", visit <company> website to purchase licenses and get free upgrades.
Writing over executable with "0101" is childish and not productive. On the day X user could have clicked on your executable by mistake and closed app. Next thing he/she knows application exits w/o warning... Is it broken? Messed up?
Would writing over executable stop even novice hacker? I doubt that. All it takes to nop area "call WriteFile[A]"...

Yes sure and I can go around a dlgbox in half a minute, so can you I guess, but I think I will stick with an original plan.
Look at the cracks available on the web for what you are advocating.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hi,
i need to export some classes in DLL created in VC++, which is fine. I understand how to use exported functions in VC++ dll from VB, but how is it (if) possible to use exported classes from VB?
I could not find any articles in MSDN / web regarding this. I would greatly appreaciate if somebody can direct me, where to get more information on this.
many thanks
Aby Philip

The question arises: are you willing to export an object of the class from the DLL, or the definition of the class ?
If it is the first one, then may I suggest that you create a global object inside the DLL's code, and export a function from the DLL which returns the address of this object. This, however, requires that you have the definition of the class available at the loading application in order to use it. I do not know for sure how well you can use C++ header files in a VB project, or if there is a conversion available.

hi friends,
i have a c++ program like this :
#include "iostream.h"
int main()
{
cout << "John" << endl;
return 1;
}
The program will print "John" on screen.
Now my problem is that i want to print "Hello John Bye" on the screen without changing anything inside main function.
CAN SOMEBODY PROVIDE ME THE ANSWER.

#include "stdafx.h"
using std::cout;
using std::endl;
class CTest
{
public:
CTest()
{
cout << "Hello John bye" << endl;
exit(0);
}
};
int main(int argc, char* argv[])
{
cout << "John" << endl;
return 0;
}
CTest test;
