C# server = a server written in C#
it uses a combination of TCPListener,network stream and binaryreader and writer to talk to client. Any ideas if these exsist in java?

Hi folks,

I've got a C# client which can currently communicate with a C# server.

I am considering re-writing the server in Java (to make it work better on Linux).

Currently, the C# setup...

Hi Folks,

I'm using this code I found online to decompress a large file. It works fine when I try it with a small file i.e. a 5MB mp3 (1.7MB compressed) but when I try and use it with a 250MB file...

Thanks you very much! :) Works great

Just wondering though, do you reckon the above code is "more efficient" than creating another temp Iterator to go through all the items (Similar to what we did...

I've got this so far:

The table structure may change in time (As different types of database may be used). The Remote.AddProduct method handles updating the table. Is it possible to use this? I'm trying to think of a way...

Hi There,

Thanks for your reply. It's very close to what I want. What I am actually doing is adding to a database and the problem I think with the above code is that it woudn't be able to do...

OK, i have managed to find a way around my problem above however I've had to change my XML structure which I don't really like.

Here is the new XML layout:

Hi folks,

I'm trying to write an XMLHandler for my epos app. The XML file (which is received by a network stream) will include multiple "operations" which may include updating the product database...

OK folks, got this sorted.

It was actually another class (My listener class) in my epos app causing it to take up 100% of CPU time. All I needed to do was add a Thread.Sleep(100) to a infinate...

Ok so the suitation gets weirder. I have found out that during the time when my epos app is trying to connect to the server (hense also the time when to touchscreen won't work), the mouse CAN move if...

Hi folks,

I have an app that will connect to a server.

My connect method looks a bit like this:

private void connect(IPEndPoint ipEnd)
{
try

hmm ok, as it turns out, i don't think its the serial port writing causing this. I forgot to mention that after the printing method is called, a few other methods are called to stores stuff to a...

Hi folks,

In my c# epos app, i have a method which does two things:

It calls a method to update the Form with the change to be given to the customer.

It then calls a method to print the...

by the way, i think I'm using completly wrong terms when I say "binary file". I think what I'm suppoed to say it "file with ESC/POS codes that outputs a bitmap"

this looks like it could do the job for me:

Hi guys,

No, this printer doesn't have on-board memory. Its the TM-T88ii (One mark below the version which does have memory).

Hi folks,

I'm sorry if this is the wrong section. I am making an application in VS2008 C# which accesses a 112MB .dbf file using OLEDB which has been taken from an old system.
Please see here...

Thanks for your fantastic help. Hopefully i'll get this solved soon :)

Also, slightly dissapointing news is that when I moved this software to a less powerful machine (As typical as it will be used), times are way up again :(

Cheers!

How do I make the database indexed? Actually, I do have an "index file" for this database (Im moving all this stuff from an old system). How do I make use of it in my program? Thanks

Thanks for your help! Using your logic, I managed to make my ole connection always open!

There does seem to be an improvement. Time is down to about 1.5 - 2.0 seconds! We're making progress.

Oh, i forgot to mention. You asked for the rest of my Return class. You have a very good point. The database seems to be VERY responsive when no match is found (indicating that search is fast..)

Thanks for your help.

As a side (but highly relavant note), I change my orignal code from odbc to ole(which uses the microsoft visual foxpro driver) and there is a huge improvement. Times for each...
