hello.im not experienced in computer .but i tried this method nd found it very funny.....i used a program in the window called hyper terminal ..you can reach to it through start up then programs then accessories then communication then hyperterminal .....throuh this program you can connect two compuers only by phone......you will adjust the sender computer to {call} and the reciever computer to {wait for call} these option is present inside the program.....
in the sender computer you will choose the phone number of the receiving computer ...and vice versa {in the sender cmputer{client} you will type the phone number of the recieving computer {server} } excuse me .is this what you want...or im not understanding what is in your mind .....with best wishes for you

This is existing in Access management system.( SAP EP environment )
The basic requirement is, with SAP EP environment we are integrating 8 different application. But for all this Application we have a one more system called Access management system (like Basis in Sap). This will validate the user access and BP(Business Partner ) data for users who logon to a different respective application. For all this applications Company data (Master Data) has to provide from CRM and the changes took place for Company data in CRM will be updated in to Virtual Directories .For this service we need to establish Delta mode connection between SAP CRM and Virtual Directories.
Which is existing in Access management system .
   Do we have any standard connectors from SAP CRM to connect and who we can achieve this .
Please let us know..Certainly there will be a reward points

Establish connection between existing IAS6.5 and newly installed S1WS6.1

How do i maintain a network connection between 2 computers

From time to time I can share my network connection between my iMac and my MacBook Air but frequently the connection is lost. How do I reconnect once the connection is lost?
Is the only choice to restart each computer?
Is it necessary that both computers remain active (not go into sleep mode)?
Any help?

If you are really sure that you want to map a network drive using Labview then the easiest way to achieve it is probably to use the System Exec.vi.
Use the NET USE command
e.g.
NET USE K: \\server\sharename password /USER:mydomain\username
Command syntax
"NET USE
[devicename | *] [\\computername\sharename[\volume] [password | *]]
        [/USER:[domainname\]username]
        [/USER:[dotted domain name\]username]
        [/USER:[username@dotted domain name]
        [/SMARTCARD]
        [/SAVECRED]
        [[/DELETE] | [/PERSISTENT:{YES | NO}]]
NET USE {devicename | *} [password | *] /HOME
NET USE [/PERSISTENT:{YES | NO}]"
Using this command you can then map a network drive using a username and password of your choice to map a drive as you require.
Note also that the user profile used to access the share can be an alternate to the local account (I am thinking domain / cross domain usage here) which is also very handy as you can use, for example, an increased security level for your LabVIEW accessing account!
There is a Microsoft knowledgebase article on the subject here:-
http://support.microsoft.com/?kbid=308582
The information also pertains to previous operating systems i.e. NT4, 2000 and XP.

Java code to make connection to web server??

Hi,
we are looking at simple java code to connect to IIS Server and retrive a ZIPed file.
this zip file contains photos. all individual photos are stored in zip file under doc root of IIS server..
any sample code will be great

Here is some code on how to open an URL and read from it.
url = new URL("http://IIS_server/doc/Yourfile.zip");
URLConnection conn = url.openConnection();
conn.setDoInput(true);
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sbResponse = new StringBuffer();
int intChar = 0;
while ((intChar = in.read()) !=-1) {
// got one byte as int from the server do something here to pass the byte from one stream to another (filestream)
// there is a way to save to the local HD with an applet but you have to sign it and adjust some security policys
in.close();

Establishing connection between BW and R/3 for BW extractions

hello all,
have learned SAP BW recently. have got BW 3.0 & R/3 installed on two different laptops. want to know how to establish a connection between them both for BW extractions.
thanks

Are the laptops connected by way of any network ?
Use the source system creation wizard for creating the source system.
Also what versions are you on ? R/3 and BW
Otherwise you can create the individual RFC connections through SM59.

How can I establish connection between DirectSoft Programming software and LookOut

Hi,
        I am working with a DL06 PLC. I am trying to a develop a LookOut Direct HMI for this tainer. I would like to know if there is any option in LookOut where it allows me to run small parts of PLC code along with HMI so that i can toggle discrete output. To be more speicifc i have X0 - 16 input bits and C0 - 16 status bits. I have to develop a logic in PLC programming so that the status bits toggels Y0 - 16 outputs on the tainer. So can you please let me know if there is any way of establishing communication between LookOut HMI and DirectSoft 32 PLC programming software.
Thanks
regards
Koneru

Kone,
Have you tried mathematics.
I use something like:
ADec2Bcd      = sum(mod(000,16),mod(trunc(000/16),16)*10,mod(trunc(trunc(000/16)
                /16),16)*100,mod(trunc(trunc(trunc(000/16)/16)/16),16)*1000);
Simply replace the 000 with the value to be converted, can be a numerical object.

MIDI over direct USB connection between two computers?

I'm trying to find out if it's possible to send MIDI between two computers using a direct USB to USB connection (no MIDI interface). I have not seen this done before, I don't think, but I don't know why it shouldn't be possible.
Thanks for any tips on making this work. I want to connect several computers together to control sound and video for a theatre production, to be triggered from a single MIDI source.

Hi,
I don't think there's something for midi over USB; however, there is an experimental tool for midi over Ethernet. It's called iMidi, and it's written foor PPC, and there's no native Intel version. I tried it with my PPC eMac and Intel iMac, but it took a lot of processing power
See http://openmuse.org/transport/mip_oview.html for more info.
You could also use a midi thru box and 2 midi interfaces to trigger 2 Macs with 1 midi source.
Hope this helps!
Kind regards,
Jaap

Establish connection between labview and Lantronix XPort Pro

Hi:
I am pretty new in this field. I just got into grad program, and I have been asked to establish a TCP/IP connection between Lantronix XPort Pro and labview 8.5. The goal is to get data from the server (Lantronix XPort Pro) and put them into labview and modify them, then I need to send modified data back into server.
The server has registered into local network wirelessly, it has IP 192.168.5.117 in port 26.
I would really appreciate your help and comments.
cheers!
Kian.

Which field are you "new" to? Programming in general? Programming in LabVIEW? TCP/IP?
Have you taken a look at the TCP/IP examples that ship with LabVIEW? There are simple Data Client/Data Server examples that show transfer of data over TCP/IP. You will likely need to do something very similar. Does the XPort Pro have a TCP/IP listener running? Do you have a communication protocol defined?
Also, if you are new the LabVIEW, have you gone through any of the tutorials? To learn more about LabVIEW it is recommended that you go through the introduction material, tutorial(s), and other material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

How to establish connection between two different IP Range

Hi All,
Currently in my office there are two different ip range that we are using one for the Wi-FI(192.168.1.X) & 2nd for local machine & servers 192.168.2.x series ip.
In current situation if any Wi-Fi user(Laptop User) wants to communicate with local machine or server then he has to switch from Wi-Fi to Lan.
So is there any way to provide communication between Wi-Fi & local network.
if this happen then there will be no need to switch from Wi-Fi to Lan, Wi-Fi user who has ip range 192.168.1.x is easily communicate with local machine & server(192.168.2.x).
Shailendra Vishwakarma

Thanx for the reply..
In my office i am using Microsoft Thread management Gateway(Software Firewall).
Can i set Security like as below,
Users can connect Wi-fi Network but they would not able to access internet but they should be able to access for local network & for the internet they should go via Microsoft Thread management Gateway.
Thanks,
