There are code samples around, via free graphing libraries. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum )

tnx a lot :)

They are generally passed as a string array to your program's entry point, although it wouldn't surprise me to find they are also a property of the Application object. Christian Graus - C++ MVP 'Why don't we jump on a fad that hasn't already been widely discredited ?' - Dilbert

U can do with many methods. 1st... U can read file with filestream and read as byte or readline and search string with "InStr" function. or looping. 2nd the best idea is "regular expression".

It looks like you've found and are using an old VB6 definition of the structures, not compatibile with VB.NET. A 32-bit integer is called Integer in VB.NET, not Long. That was the old VB6 name for it. Long under VB.NET is a 64-bit integer. If you don't get this correct, you can imbalence the call stack. The function declaration should be this: Declare Function Auto GetTcpTable Lib "IPhlpAPI.dll" ( _ ByVal pTcpTable As MIB_TCPTABLE, _ ByVal pdwSize As Integer, _ ByVal bOrder As Boolean) As Integer Dave Kreskowiak Microsoft MVP - Visual Basic

I don't know of any examples. Probably because they all involve writing a packet driver that sits in the network stack. This packet driver should expose an interface to pass the traffic to an external application and then get a response back to tell it wether or not to continue passing the traffic up the stack or to discard it.

You'll need to write, or find, a packet driver that will allow your code to see all the traffic comming acrossed the machine wire. There is a problem with this though. A switch will not let you see all the traffic on the subnet your machine is connected to. You will only see the traffic directed at your sniffing machine. Sniffing a network is best left up to the switch itself (if available), where it forwards all the selected traffic to a specific machine on the network. Dave Kreskowiak Microsoft MVP - Visual Basic

No, there isn't. You code STOPS executing, immediately. You don't have any way of detecting this if your no longer running. Dave Kreskowiak Microsoft MVP - Visual Basic
