Then you need to sort the array (descending oder, i.e. highest to lowest), then take the second element.
|
|
|
|
|
or loop through the array after sorting to check if the value arr[n] is different from arr[o] and take that value.
It depends if you can guarantee uniqueness of items

Hi Guys,
has anyone ever done anything like interact between two programs?
I have one program that authenticates people based on their biometric data written in MFC (one EXE).
Now i'm writing another program for medical records. (Another EXE).
How do i know when the biometric authenticating program has finished authenticating, and its result, i.e: true or false.
I need to run the first program, then based on its results, run the second. Any help please. I'm stuck!
Help!

What external interfaces does it provide?

Do you mean that the authentication program does the authentication, exits with some sort of return code which your second program can then use to determine if it can continue or not? If so then that really sucks! There is no real security in that scenario, the first program could potentially be swapped out easily by something malicious.

Colin,
the program exits with no exit code. After identifying, it exits normally. All i'm saying is, before its exit, how do i know if it identified the person as already registered, or not.
i was thinking i could write a value, like 0 or 1, to a file then use a timer from the second program to check the value written. Is that logical and safe?

please can u give a scenario on how u did this.
Big thanx.

File systems are too easily compromised. Also this method is increadibly inefficient.
Creamboy wrote: please can u give a scenario on how u did this.
There are tons of scenarios. WCF (Windows Communication Foundation) is the way to go these days as it encompasses so many ways of communication in a consistent way.
The first thing you really need to do, based on your replies, is to buy a book on security and read it. This is one area where writing code based on a little information can get you in to real trouble. You need to really understand how your system hangs together. Without that knowledge you'll end up blowing great big security holes in your system.

i've used remoting to do this before.
You have to watch out for "man in the middle" type attacks as Colin said.
I would guess you want some kind of 2 way authentication to ensure that the authorisation component isn't compromised
|
|

|

Russell, please could you explain how you achieved this with remoting. Although, i have an idea of remoting i've never used it. What about the writing to files method? Is that okay?

Hello everyone,
I can not find answer from MSDN. My question is, when Console.ReadKey is called on a thread,
1. the thread will be still in running status (like we call Sleep), which will consume CPU time?
2. or the thread will be in wait status like we call WaitOne, and keyboard press will signal the event?
thanks in advance,
George

ReadKey will block till it gets a key press. IT should not use any CPU while in this state. I am not sure what you mean by the rest of the question.

Thanks leppie,
Question answered. Cool!!

Hi everybody,
in my project i receive via sockets an array of bytes.
I send the data from a C++ application to my C# instance.
The Byte-Array is decoded via ASCIIEncoding.ASCII.GetString()
For all standard-chars it work fine, but special characters like ä,ö,ü
aren't translated correctly.
I did a test with a loop, which creates me a byte-array from 0 to 500
then i decode it with ASCIIEncoding.ASCII.GetString() into a string.
I can't find the ä,ü,ö characters into the created string.
if i write string s = "äöü"; the characters are also recognized and are
working correctly.
How i can translate my byte-array that i get the correct characters?
Big thanks for any help

Use Encoding.Default or a UTF8 or Unicode one.
|
|
|
|
|
I've tested different encodings, UTF8, Unicode, ... nothing worked for me
then a simple Encoding.Default, like you told me works perfect
Big thanks to you !

Run away!!!
Seriously, what source control are you on now? Why do you think that VSS is a better solution?
You might want to look at other solutions such as SourceGear's Vault. Eric Sink has some excellent tutorials on using that.

hi,
m asking about vss couse i have never heared about athour solution,
i have noticed that vss is bad!!!

Hello,
I think this is the first time i post a question on the codeproject, so hope it goes well
So, the question is:
How can i lock a file while it is being written so that other processes cannot move/delete or access it.
I have a file that is being written into by an application on a remote machine and a windows service on the local machine that connects to the remote machine and downloads that file.
The problem is that i want to download the file only after the write process has stopped completely.
How can this be done?
And a related question: How can this be done if i try to download the file from a ftp server.
Both remote and local machine are under XP and the applications are written in c#.
Thank you
