Executing a simple assembly program using legion

How do I execute a simple assembly program using Legion simulator and view the registers?

I tracked down the problem and it is a race condition between the many processes being started up. A smaller delay should also solve the problem. Or, maybe do something else before the first 'load'. The 'load' command tries to launch systembuild and causes the race condition.

java.security.AccessControlException: access denied (java.io.FilePermission
<<ALL FILES>> execute)This message tells you that the applet does not have permission to access/execute files. Access may be granted by either signing the applet, which allows the user to grant (or not grant) the access when running the applet, or by adding the necessary permission file to the user's computer.

Client Server program using Applets for client

Creating a client server program using Applets for the clients.
Having problems distrubting the message from client to client
using ObjectOutputStreams/ObjectInputSteams.
I can connect each client to simple server and respond with by writting
the i/o stream of each client but unable to communicate from client to client. If any one out there has in tips of creating a class of objectOutputStreams that holds a array of ObjectOutputStreams and then broadcasts the message to every client, it would be much appreciated
Thanks.

Cheers poop for your reply
I never explained the problem properly. What it is I am trying to set up a Client Server program using Applets as the clients GUI. The problem is broadcasting the message to multiply client connnection(s).
Below is code, each client can connect and send message to the server. The problems is broadcasting the message to every client connection. The every client can input a message but only the last connected client can receive the message?????? Thanks in advance..

[Standalone Program] simple I/O using hyperterminal

any thought?

When I try to open an embedded PDF file I get an error "The program used to create this object is AcroExch.exe.

When I try to open an embedded PDF file (Word doc) I get an error "The program used to create this object is AcroExch.exe. That program is either not installed on your computer, or is corrupt..." I've tried about everything from unchecking
protected mode at startup to removing & reinstalling Adobe. Nothing seems to fix this issue. Any other ideas?
This is happening on Adobe reader 9, 10 & 11 with MS Word 2010 & 2013. I've uninstalled, cleaned & reinstalled Reader 9, 10 & 11, as well as Acrobat 10 Pro & 11 Standard. Removed "Protected mode at startup, and changed
the default program for viewing from reader to Acrobat. This will not go away. It is affecting production at our company.

" Help > Troubleshooting Information > Profile Directory: Open Containing Folder" . i can't find open containing folder in profile directory. it does give me the option to open the places.sqlite file using graphic converter. when i try that, graphic converter gives me a window saying that it can't be opened because it is corrupted or is not a file type supported by graphic converter.
i appreciate your help with a workaround to get the old bookmarks. that works. however, the problem has morphed from that concern to why adobe reader [the default app.] won't open firefox .sqlite files. is the problem in adobe reader or firefox? also, how can i tell if the places.sqlite file is corrupt?
i'm getting in over my head here and do appreciate your help.

"Assertion failed" error when executing a simple UCI program

I am using a simple UCI program (tt1.c) with Xmath version 7.0.1 on Sloaris 2.8 that performs the followings:
- Start Xmath701
- Sleep 10 Seconds
- Load a sysbuild model
- Stop Xmath
I am calling the uci executable using the following command:
> /usr/local/apps/matrixx-7.0.1/bin/xmath -call tt1 &
In this way everything works fine and the following printouts from the program are produced.
--------- uci printout ----------
## Starting Xmath 701
## sleep 10 seconds
## load "case_h_cs_ds.xmd";
## Stopping Xmath 701
All the processes (tt1, XMATH, xmath_mon, and sysbld) terminate correctly.
The problem occurs if the 10 second wait after starting xmath is omitted:
- Start Xmath701
- Load a sysbuild model
- Stop Xmath
This results to the following printouts:
--------- uci printout ----------
## Starting Xmath 701
## load "case_h_cs_ds.xmd";
Assertion failed: file "/vob1/xm/ipc/ipc.cxx", line 420 errno 0.
Note that the last line is not produced by the uci program and the tt1 did not
finish (the printout before stopping xmath "## Stopping Xmath 701" was
not produced).
A call to the unix "ps -ef" utility shows that none of the related process has been terminated:

The questions are as follows:
1- What is "Assertion failed: file "/vob1/xm/ipc/ipc.cxx", line 420 errno 0" and why is that produced?
2- Should the UCI program waits for end of sysbld initialization before issuing commands?
3- If the answer to the above question is yes, is there a way to check the termination of sysbld initialization?
Thanks in advance for you help.

I tracked down the problem and it is a race condition between the many processes being started up. A smaller delay should also solve the problem. Or, maybe do something else before the first 'load'. The 'load' command tries to launch systembuild and causes the race condition.

Please help us to fix this bug in proxy response.

Hello Ravinder,
Can you please post the complete stack trace, it seems to be some fields are getting truncated i,e data sent from the program to the proxy object might be violating some length restrictions.
Please check your message interface field lengths and what is being passed to the proxy.

Ravi.

My DAQ program uses Traditional NI-DAQ in Visual C++ 6.0. I get error-10609 at SCAN_Start when run

My data acquisition program uses Traditional NI-DAQ in Visual C++ 6.0. When I run the program, I get error -10609 at the SCAN_Start that states
A transfer is already in progress for the specified resource, or the operation is not allowed because the device is in the process of performing transfers, possibly with different resources.
Why do I receive this error?

Hi,
TThe error -10609 can result from several situations in which the device's resources are already in use.
A Measurement & Automation (MAX) test panel is already open.
If you open a test panel window for your device and attempt to run your application, you can get this error. If this is the case, close the MAX test panel.
An AI Clear function was not used at the end of the previous acquisition.
If you do not call the AI Clear function after performing your acquisition, the resources remain open. Be sure to call this function, inputting your taskID, at the end of the acquisition.
Multiple programs are accessing the device.
If you have multiple VIs accessing the device, or perhaps a LabVIEW VI and another application, the resource will be taken and you will receive the error. You can only run one application accessing the specific resource (for example, analog input on channel 0) at a time
I hope this helps...and have a Great Day!

Problem with simple label program

I'm getting a problem to a most basic program. I'm using the Java2 Fast And Easy Web Start book. This simple label program gives me an error when I compile. This is the program
//Label Program
//Danon Knox
//Another basic program
import java.awt.*;
import java.applet.*;
public class Label extends Applet{
public void init(){
   Label firstlabel = new Label();
   Label secondlabel = new Label("This is the second label");
//put the labels on the applet
add(firstlabel);
add(secondlabel);
}// end init
}// end appleterror when I compile is as follows:
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
C:\>cd java
C:\java>javac Label.java
Label.java:12: cannot resolve symbol
symbol : constructor Label (java.lang.String)
location: class Label
Label secondlabel = new Label("This is the second label");
^
1 error
C:\java>
Can anyone help me?

public class Label extends Applet{The name of your class is "Label". This choice of name hides the class named "Label" in java.awt.
Label firstlabel = new Label();This creation of a Label is successful because the class has a default, no-argument constructor.
Label secondlabel = new Label("This is the second label");And this one fails because there is no constructor for Label that takes a String argument.
You probably want firstlabel and secondlabel to be java.awt.Label objects and not instances of your own Label class. Try this:
public class Label extends java.applet.Applet{
    public void init(){
     java.awt.Label firstlabel = new java.awt.Label();
     java.awt.Label secondlabel =
         new java.awt.Label("This is the second label");
     add(firstlabel);
     add(secondlabel);
}As a general remark, I advise programmers to stay away from
import a.b.*;statements which import entire packages into your program namespace.
When starting out, I believe it is better to write out the fully qualified names ot the classes and methods you are working with. This helps you learn the class hierarchy, and makes your code clearer.
Others will disagree, but that's my opinion...
