What is the problem with this simple script

This shouls work to open safari:
tell application "Safari"
activate
end tell
But I get error:
error "Safari got an error: Connection is invalid." number -609
So what is wrong? Other apps work such as:
tell application "Adobe Bridge CS6"
activate
end tell

Ah the Devils in the details.
With the quit like that there is the potential for error. When I add the quit I see either Safari not opening or else I get the connection error also.
There are ways around this either put in a delay between the quit and the activate or else superficially check to see if Safari has quit.
so
tell application "Safari" to quit
repeat while application "Safari" is running
end repeat
tell application "Safari"
activate
end tell
or
tell application "Safari" to quit
delay 5 -- increase or decrease as needed
tell application "Safari"
activate
end tell

What's the problem with this Ajax code?

The B.cfm:
<cfimport taglib="/tags" prefix="Tag">
<Tag:_ImportprocessingTime>

do some long loop......

</Tag:_ImportprocessingTime>
the ajax code to execute the b.cfm:
function Importxls(url,buttonid,msgid,dbffilename)
createXMLHttpRequest();
var url=url+"?importdbffilename="+dbffilename+"&ti="+new
Date().getTime();
xmlHttp.open("GET",url,true);
xmlHttp.onreadystatechange= function()
if (xmlHttp.readyState < 4)
document.getElementById(msgid).innerHTML= "importing......";
document.getElementById(buttonid).disabled=true;
else if (xmlHttp.readyState == 4)
if(xmlHttp.status == 200)
document.getElementById(msgid).innerHTML=xmlHttp.responseText;
document.getElementById(buttonid).disabled=false;
else if (xmlHttp.status == 404)
document.getElementById(msgid).innerHTML="URL error";
document.getElementById(buttonid).disabled=false;
else
document.getElementById(msgid).innerHTML="error，xmlHttp
state："+xmlHttp.status+"。";
document.getElementById(buttonid).disabled=false;
xmlHttp.send(null);
when I execute the b.cfm ，the spended time only about
5 seconds and show the result right now.
but when I execute the b.cfm through the ajax
code，after about 60 seconds,it shows the result,why?and how
to let it show the result after the b.cfm executed?
Thanks a lot.

Vector, what is the problem with this code?

Vector, what is the problem with this code?
63 private java.util.Vector data=new Vector();
64 Vector aaaaa=new Vector();
65   data.addElement(aaaaa);
74 aaaaa.addElement(new String("Mary"));on compiling this code, the error is
TableDemo.java:65: <identifier> expected
                data.addElement(aaaaa);
                               ^
TableDemo.java:74: <identifier> expected
                aaaaa.addElement(new String("Mary"));
                                ^
TableDemo.java:65: package data does not exist
                data.addElement(aaaaa);
                    ^
TableDemo.java:74: package aaaaa does not exist
                aaaaa.addElement(new String("Mary"));Friends i really got fed up with this code for more than half an hour.could anybody spot the problem?

I can see many:
1. i assume your code snip is inside a method. a local variable can not be declare private.
2. if you didn't import java.util.* on top then you need to prefix package on All occurance of Vector.
3. String in java are constant and has literal syntax. "Mary" is sufficient in most of the time, unless you purposly want to call new String("Mary") on purpose. Read java.lang.String javadoc.
Here is a sample that would compile...:
public class QuickMain {
     public static void main(String[] args) {
          java.util.Vector data=new java.util.Vector();
          java.util.Vector aaaaa=new java.util.Vector();
          data.addElement(aaaaa);
          aaaaa.addElement(new String("Mary"));
}

What is the problem with this Stored Procedure

Hi ,
What is the problem with this Stored Procedure ?Why is it giving errors ??
CREATE or replace PROCEDURE getEmpName
*(EMP_FIRST OUT VARCHAR2(255))*
BEGIN
SELECT ename INTO EMP_FIRST
FROM Emp
WHERE EMPNO = 7369;
END ;
*/*

You don't specify precision in procedure arguments.
(EMP_FIRST OUT VARCHAR2(255))should be
(EMP_FIRST OUT VARCHAR2)Since you asked what's wrong with it, I could add that it needs formatting and the inconsistent use of upper and lower case is not helping readability.

What is the problem with this code ? Race condition??

Guys,
The idea behind the attached code is quite simple.
I have a 2D parent array. First, I print a subset of this array into a table control (based on a sensor selection). Now, I want edit the numbers in the table. I need the changes to be reflected in the table and the parent 2D array. (In simple terms, this is like replacing the the edited array subset into the parent 2D array)
The problem is when I change(edit) any entry in the table, the entry changes back to its original value. The change doesnt seem to be reflecting on the parent 2D array and the table. .
Can anyone tell me where the problem is?
Thanks
Ravi

I agree with Chris, here's an idea (of whatI think your code does):
The case structure in your code was unnecessary, all the cases were the same so I removed them.
The sequence structure was unnecessary.

What is the problem with this Xcopy in PostBuild?

I am having the following post-build command in a Visual Studio project:
xcopy $(ProjectDir)Data $(OutDir)\
The Data is a directory in the project folder which I want to have copied to bin/debug or bin/release after build completes successfully.
I am getting an error as below:
The command "xcopy E:\Lavanya Deepak\Projects\matrimonial\Data bin\Debug\" exited with code 4.

Why are you using Xcopy for something that Visual Studio can do already?
http://support.microsoft.com/kb/306234
http://msdn.microsoft.com/en-us/library/0c6xyb66%28v=vs.80%29.aspx
Besides, this is a issue with XCOPY, not with Visual C# or Visual Studio (wich this forum is about). Perhaps you better look into the documentation or ask in a admin Forum?
-1 for not an answer to the question.
This does not address the need for XCOPY. This is NOT an answer. How does this help transfer *.ascx files along with the compiled code behind into the respective directories of a local website for debugging. Umbraco requires this as an example.
Also, this could be an issue with Visual studio as the XCOPY works in VS 2012 and via the command prompt but NOT VS 2013 for me.

Custom tables create in Apps schema ( What are the problems with this?)wwww

Hello all,
I'm a dba in a new environment where a number of custom schemas are being created in the apps schema. I know this is not considered Oracle's best practice and I would like to make some recommendations for a change. Before doing so, I would like to know the problems that are associated with custom tables living in the apps schema. We are currently on 11.5.10.2 on AIX. Also, if someone can point me to any "Official" customization standard or Oracle documention where I can backup my case it would be greatly appreciated.
Thanks in advance,

What's the problem with this CC stuff?

Since CC is available I only have trouble with all this stuff. I'm on OSX ML and there seems to be no change to install anything of the new stuff. CC app desktop- failed to install. When I use AAM, the CC apps are available, but after downloading I get an installation failure (15). I've tried anything discussed in this community, but nothing worked. So why there are so many problems with CC? Since I pay over 60 Euros each month, I would like to use the promised applications. ADOBE, please supply a reliable solution for all operating systems without the need of erase data, rename folders or anything else. Thanks in advance.

What is the problem with this script. it is giving invalid table name error

declare
l_cnt number;
v_sql varchar2(1000);
table_name1 varchar2(1000);
begin
for i in ( select table_name from all_tables )
loop
table_name1 := i.table_name;
v_sql := 'select count(1) from :table' ;
execute immediate v_sql into l_cnt using table_name1;
dbms_output.put_line(l_cnt);
end loop;
end;

the problem is that you can't do that. it's illegal. use dynamic sql.

Can you figure out what was the problem in this simple 3 liner code?

Hello, below is a class to demonstrate a problem I see that I can't understand. I create an instance of the enclosing
class at class level, another instance in static main method. Class below fails at run time with stack overflow exception. It's all fine if one of those two instantiation steps is removed, What is wrong can anyone any ideas?
public class App
// create instance of this class
App app = new App();
public static void main( String[] args )
// create instance of this class again.
App app2 = new App();
System.out.println( "Hello World!" );
}

As soon as a new instance of 'App' is created, 'App app = new App();' is called, which calls 'App app = new App();' etc. Hence the stack overflow.
When you remove 'App app = new App();', obviously, the stack overflow does not occur. And when your remove 'App app2 = new App();' the 'App' class is never instantiated and therefore, the exception is also not thrown.

What is the problem with this code?

dear sirs...
i have a page that does not contain any binding, it contains the following event:
public void onCheck(DataActionContext ctx)
ViewObject V=ctx.getBindingContext.findDataControl("AppModuleDataControl").getApplicationModule.findViewObject("empview1");
V.setWhereClause("");
V.executeQuery();
V.first();
note that the above code works if the table emp is on the page, however, if the page is not bound to the page (it does not contains the table) the statement in the bold will fire an exception saying that there is no binding. i am sure the V is not set to null.
another problem appears, if i put the table and execute it within jdeveloper, it works correctly, however, if i run if i deploy the application into application server, the code never runs as if there is some kind of an error.
i hope that you can anser me about the following;
1- if the code above correct?
2- how can i view the log for the application?
3- System.out.println("test"); in jdeveloper works okay, in the application server, does it cause some kind of an error?
thanks for any help & best regards

If you don't close the ResultSet, different things happen based on which database you're running. You can keep read locks that you don't need. It wastes resources, and as different databases react differently to it, you might have weird bugs down the road that result from your practices of not properly closing ResultSets, PreparedStatements, and Connections. Put this in a loop like you've got here, and the effects may or may not get amplified.
I write a close() for a ResultSet just as soon as I open it, just to make sure I don't forget. In a situation like this one, I would write something like so:
for(int i = 0;i<someValue;i++)
try
//some code
rs = pstmt.executeQuery();
//some code that uses rs
catch(Exception e)
finally
if (rs != null)
rs.close();
if (pstmt != null)
pstmt.close();
}
