Can you tnsping to oracle database ? After installation if you chose different oracle home for developer then you have now two tnsnames.ora files. One in oracle database home and the other one in oracle developer home.
Read about TNS_ADMIN environment variable here..

How can i deal with this problem

For example, In my database, there are three records:
field : a b c
a.txt c:/a.txt adsfs
b.txt c:/b.txt asdfsf
c.txt c:/c.txt asfdsf
Now I open one file b.txt to check the database whether have the same filename,filepath, hash value.
the results display:
The file: b.txt has not been registered
The file: c://b.txt appears OK
The file: b.txt has not been registered
I want to do is to only shows the results of 'The file: c://b.txt appears OK'. I know the problem is the body of while(rs.next).
is there any best way to conform to my demand
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url="jdbc:odbc:MD5";
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM MD5";
ResultSet rs = statement.executeQuery(sql);
while (rs.next()) {
if (file.getName().equals(rs.getString("a")))
if (file.getPath().equals(rs.getString("b")))
if (m.equals(rs.getString("c")))
jTextArea2.append("The file: " + file.getPath() +"appears OK"+"\n");
else jTextArea2.append("The file: " + file.getPath() +"has been modified"+"\n");
else jTextArea2.append("The Path for the" + file.getName() +"has been modified"+"\n");
else jTextArea2.append("The file: " + file.getName() +"has not been registered"+"\n");
rs.close();
connection.close();
}

Why not add a WHERE clause to your statment to filter records having the name of the file in the first record. In this case you'd better use PreparedStatement and set the file name as statement parameter
Because now you loop through the entire table for a thing you can deal with at DB level.
And I agree with the others' remarks about those braces ;)

Have purchased a new computer but can not install elements 12 since it has been installed on old laptop. Is there a small fee to be able to do this. Never installed the video editing portion, can this be installed with no problem?

Have purchased a new computer but can not install elements 12 since it has been installed on an older laptop. This is a one time user program, is there a code that can be put in or a small fee to pay to be able to use the program again. Never installed the video editing and hoping this can be installed with no problem.

If the laptop is still connected Launch Elements in Expert Mode. Go to the help menu and sign-out. That will deactivate usage on the laptop.

How can I deal with long sql by the oo4o?

I am using VB and oo4o to develop a sql executor which is a extention of an old system.
For some reason, I have to use oo4o v8.1.7 to deal with Oracle Database 8i to 11g.
But when I send a very long sql(11KB) to it I got a error in the VB enviroment.
The Err.Description is "automention error. Started object is disconnected by the client.".
The Err.Number is "-2147417848 ".
The sql that I send it to the program is a simple select sql that like select a, b, c, substrb(d, 1, 2), substrb(e, 2, 3) .... from A_TBL where A=aa;
This sql is normally executed by the sqlplus but I got an error by the oo4o.
When I insert a '' between the 30Xth items, it got exectuted normally.
ex. select a, b, c, substrb(d, 1, 2), substrb(e, 1, 2) ..... substrb(303th, 3, 4), '', substrb(304th, 1, 2) ... from A_TBL where A = aa;
How can I deal with this problem? Thanks.

So how can use this function correctly?By learning what exceptions are, how they're used, and what you can do to deal with them. There's a tutorial here: http://java.sun.com/docs/books/tutorial/essential/exceptions/index.htmlAnd here's a quick overview:
The base class for all exceptions is Throwable. Java provides Exception and Error that extend Throwable. RuntimeException (and many others) extend Exception.
RuntimeException and its descendants, and Error and its descendants, are called unchecked exceptions. Everything else is a checked exception.
If your method, or any method it calls, can throw a checked exception, then your method must either catch that exception, or declare that your method throws that exception. This way, when I call your method, I know at compile time what can possibly go wrong and I can decide whether to handle it or just bubble it up to my caller. Catching a given exception also catches all that exception's descendants. Declaring that you throw a given exception means that you might throw that exception or any of its descendants.
Unchecked exceptions (RuntimeException, Error, and their descendants) are not subject to those restrictions. Any method can throw any unchecked exception at any time without declaring it. This is because unchecked exceptions are either the sign of a coding error (RuntimeException), which is totally preventable and should be fixed rather than handled by the code that encounters it, or a problem in the VM, which in general can not be predicted or handled.

According to a random website... the HTC Wildfire S uses a Qualcomm MSM7225 processor. This processor unfortunately does not support the full ARM version 7 instruction set, so Firefox cannot run on it.
