There are several methods you could use - WCF, sockets, HTTP...
What are your requirements? What kind of data?.45 ACP - because shooting twice is just silly

Thanks for your reply.
I need to send at least 2 and up to 7 separate strings. In essence, the user will be sending some authentication data to the server which will consists of an authentication code and some other identifying information (e.g. a MAC Address, user ID, etc...).
This will enable me to uniquely identify the user in the database on the server. Then, once the server has certified that the user is unique or doesn't exist, then it will send back an authorization which will either be, I suppose, true or false, etc...
Thanks again.

If the server is a web server, you could use a web service to do that.
If the user has an account on the server, he could just use the built-in .Net authentication stuff.
If the server does not meet any of those criteria, I'd use sockets..45 ACP - because shooting twice is just silly

Hi,
Can someone point me in the right direction on how to search through all files over multiple drives to look for duplicates?
Thanks in advance!
|

Hi,
1.
there must be lots of utilities around that do this, some even for free.
2.
if I were to develop one, I would enumerate all files and calculate a checksum for each; then investigate files with matching checksums only.
Warning: different partitions/devices can use different file systems, resulting in slightly different dates (e.g. FAT is accurate up to 2 seconds only), and maybe even slightly different sizes.
[ADDED]Also Daylight Saving Time conventions may be different on different machines on a network.[/ADDED]
Anyway, this would take a while, as all data has to be read from the disk(s) to do it properly. One can not simply rely on file names!

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. All Toronto weekends should be extremely wet until we get it automated in regular forums, not just QA.

Hi,
I know there are a few tools around that can do it. I'm just in it for the experience.
What do you mean with calculating a checksum?
|
|
|
|
|
something like a longitudinal checksum, summarizing all the data into a short number, so you can store it in memory and compare. Equal files are bound to have equal checksums, and equal checksums probably (but not absolutely) indicate identical file contents.
Google or other search engines should be your friend; you might read this[^] and more.

Comparing file contents is slow, so you only want to do it when you have to. You can go through the drives and build a hash table of files and their sizes. Different sizes mean no duplicates.
For the files that have the same size, the next step is to look at contents (I'm assuming you also want to detect duplicate contents stored under different names, or with different times.) You could store check sums with the files, as Luc suggested, but check sums could be wrong for similar files. They can be used for avoiding comparing file contents: If the check sums are different, the files are different. But if they're the same, you have to look at the contents for confirmation.

| i have a digital persona reader on my laptop and i wanted to test for finger print reading integration in my custom application. how can i do this? Wamuti: Any man can be an island, but islands to need water around them!

You might need to contact the hardware manufacturer for some documentation. There are samples available on the internet if you do a search, but they may not work with your fingerprint reader drivers.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...

i intend to use the speech library but the poblem is i didn't manage to include this library in my project (using SpeechLib didn't work)
|

Please post your code.
We don't know what library you are using, what error message you are getting (assuming it's not just responding at all).Antoine de Saint-Exupery: Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

what i want to do is to create a voicespeech that will "say" a message that i have already written.. so what i'm doing is that i'm including "using SpeechLib;" and then when i want to choose "SpVoice" method it won't show up .. so i couldn't use it.. that's the problem

OK, lets try the obvious stuff first:
1. Have you added the Assembly to the project (as per the first picture on the answer here http://social.msdn.microsoft.com/Forums/en/vbpowerpacks/thread/87c15a18-dd30-4ebd-9775-3777c3225168[^]
2. Sometimes [often] the intellisense on Visual Studio goes wrong. Have you tried restarting.
If you've tried 1 & 2 you'll need to post some code so we can see what might have happened.Antoine de Saint-Exupery: Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

Hello guys ..... I have developed my own POS System using C# which supports POS Printer and Normal printers ... But this days in our country the Government came with a new POS Printer which is called BNC Printer. I think what makes this printer different from others is that it has a network connection with the government which sends every transaction to their Database. But my POS System is not unable to print using this printer. Even the Printer doesn't have a driver ... So any body who has an idea on how to work on this Printer, Please help me??? ... Other wise my System will be out of use a little bit latter ... Please help me .. Thank you.

There are some software companies whose POS System works on this new printer!!! ... So there must be some dll file or a code which helps to print !!! any clue??
|
|
|
|

sure, just look at how they do it. Maybe the printer works with an existing driver. Maybe there is a driver you don't know about. And maybe there is sufficient documentation and some company did create a driver, so you can go and negotiate with them.
Whatever it is, enforcing the use of a specific printer and not providing a solution to the driver situation makes no sense.

Since this is a business , no body is not willing to give what they got!!! It is like find the dll file from some where else then write a code by your self..... @ least if we got any file,documentation or dll file .. I will probalby do the rest of work my self ... But do u think that I cant get any documentation online??

How could I possibly know, you did not even mention the manufacturer nor exact model?
