I add the .dll and .lib to the linker options and #include the cooresponding .h file to the project. I can't get the program to recongnize the function in the .dll and .lib correctly. It seems that .NET does not like the way the functions in the .h file are declared, or something? Is there something new in VC.NET that I need to know with regards to using .lib and .dll? Help!

Best Regards, Irshad general question about network traffic detection SireNexus17-Jun-04 23:27 SireNexus 17-Jun-04 23:27  Hello, i want to develop a tool for winXP that dynamically limits Intenet (IP) bandwith on a LAN host (LAN connected to Internet via router). the tool should run on all LAN clients and send information about the current IP traffic on the client to the other clients. with this information it should limit the bandwith to a predefined value, if the other clients need full bandwith, too. for example: if three clients need full bandwith all get limited to 1/3 of the full bandwith available. if just one client need full bandwith it should get all. thats the theory. to manage this, i need to detect the current ip traffic on a client. searching the web brought me to MS IpHlpApi.lib but it only detects IP datagram amounts, not the real size if an ip-packet. next solution is ip-packet sniffing, but this need as far as i now, developing a kernel mode driver. i know about pcap library for packet sniffing task but it doesnt allow packet manipulation. i dont need packet manipulation for my task, but ive got another project in mind that does, so i want to go the straight (maybe hard) way. i thought about using MS Visual C++ with MFC and DDK so my question: what would you suggest for solving my problem? best regards Robert Re: general question about network traffic detection Trollslayer18-Jun-04 1:34 Trollslayer 18-Jun-04 1:34  This sounds like any firewall code would do that.

I need to check if a specified directory exists. If not, I must create it (a complete path is specified). How is the best way to do that ?

Thanks, that worked . Re: Check for existing directory James R. Twine18-Jun-04 11:47 James R. Twine 18-Jun-04 11:47     Why not just call CreateDirectory(...) and be done with it?  If the directory does not exist, it will be created and if it does exist, you will get back an ERROR_EXISTS error code.  Either way, you get want you want and will likely be faster than doing you own check(s) first.    But the Shell LWAPI function PathFileExists(...) was designed for checking for the existance of files/directories...    Peace! -=- James Tip for SUV winter driving survival: "Professional Driver on Closed Course" does not mean "your Dumb Ass on a Public Road"!

Shaw 17-Jun-04 22:06  What I am looking for is a state machine diagram showing how to decipher a regular expression. I've searched the www and have half a dozen pieces of source code that process regular expressions, plus I've read more articles on NFA's and DFA's than I care to think about. None of them give me what I am looking for. I am working on developing my own diagram, but it is far more complicated than it appears on the surface. I've written DFA's to handle kown cases (keywords,numbers,etc..), but what I want is to allow the user to enter in a regular express that my code can use to generate a (specific) DFA in memory.
