Execute delay only once the entire time

I need ideas on how to execute a delay only once after start (and that's it, no more calling the delay ever again after start) in a while loop without affecting other codes in that same loop...
Something like this http://forums.ni.com/t5/LabVIEW/put-a-delay-for-executing-case-structure/m-p/1095396/highlight/true#... but it is not working

Why? That makes no sense. You need to change the loop termination inside the subVI as I already mentioned.

Servlet executes only once, the first time???

Hello evrybody,
I'll try to be specific regarding the problem. I have an HTML file called Login.html. When I click on this file, a page opens allowing the user to enter his/her username and password. So, I compiled my servlet and I clicked on the Login.html file. I entered some existing username/password combination and the new page opened saying "Login Succesful!". I then close that page and go and click on Login.html again. This time I enter some username/password combination that is not existing in database and according to my servlet a new page is supposed to be opened with a message saying "The username and password you provided are not valid. Please register first!". But, what happenes is that a blank new page is opened with no message (also same thing would happen even if I provided the valid username/password combination). What could cause this? I tried to put rs.close() in the code (rs is reference to a ResultSet object) but it does not make any difference. Can anyone give me a clue about what might be causing this strange behavior? Thanks in advance,Jimmy.
The code for my servlet is provided below:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
import java.io.PrintWriter;
public class LoginServlet extends HttpServlet {
     String jdbcDriver="sun.jdbc.odbc.JdbcOdbcDriver";
     String dbURL="jdbc:odbc:Schedule";
     Connection dbConn=null;
     public void init() throws ServletException {
          try {
               Class.forName(jdbcDriver).newInstance();
               dbConn=DriverManager.getConnection(dbURL);
          catch (ClassNotFoundException e) {
               throw new UnavailableException("JDBC driver not found:"+jdbcDriver);
          catch (SQLException e) {
               throw new UnavailableException("Unavailable to connect to: "+dbURL);
          catch (Exception e) {

                         HttpServletResponse response) throws IOException {
          try {
                    PrintWriter out=response.getWriter();
                    Statement stmt=dbConn.createStatement();
                    String username=request.getParameter("username");
                    String password=request.getParameter("password");
                    String sql="select UserName,Password from Personal_Info where Personal_Info.Username='"+username+"' AND Personal_Info.Password='"+password+"'";
                    ResultSet rs=stmt.executeQuery(sql);
                    if (rs.next()) {
                         out.println("<HTML><HEAD>");
                         out.println("<TITLE>Meeting Scheduling Page</TITLE>");
                         out.println("</HEAD>");
                         out.println("<BODY>");
                         out.println("<H2>Login Succesfull!</H2>");
                         out.println("</BODY></HTML>");
                         out.close();
                         rs.close();
                    else {
                         out.println("<HTML><HEAD>");
                         out.println("<TITLE>Please Register First</TITLE>");
                         out.println("</HEAD>");
                         out.println("<BODY>");
                         out.println("<H2>The username and password that you provided are not valid!</H2>");
                         out.println("<H2>Please enter the valid username and password or register first.</H2>");
                         out.println("</BODY></HTML>");
                         out.close();
                         rs.close();
          catch(Exception e)     {
                    e.printStackTrace();
          finally {
                    try {
                         if (dbConn !=null) {
                         dbConn.close();
                    catch (SQLException ignored) {

I solved the problem by using destroy() method instead of finally block. Thanks,anyway,Jimmy.

Delay on playing an instrument (only at the first time)

Hello,
I'm new to Mainstage and have the following problem:
Always I open my concert, there is a small delay in all instruments in all patches. But ONLY at the first time, I play the instrument (hit the key). For the rest of the performance everything works fine ... How can I get rid of that??
My work-around right now is, to mute the Main Audio at the soundcheck and play every instrument/patch once ... :-(
Thanks for your support and greets from Germany
... Joonas

Thanks for your answers first of all !
At the end I found the solution looking at the Note:307167.1 on Metalink:
Discoverer Plus 10.1.2 Fails with ORA-1017 Error On First Login Attempt Then Works On Second Attempt
This note is very useful but into the solution the point 3 is not correct !
3. Modify the servername parameter to indicate the fully qualified servername.domain
Example:
An httpd.conf setting of: ServerName my_servername.mydomain.com should match a Discoverer Plus URL like http://my_servername.mydomain.com:7778/discoverer/plus
I had this problem both with Viewer and Plus...so instead to change the server name parameter (into the Apache/Apache/conf/httpd.conf file) with my complete URL (http://gnvdev.ote.gr:7779/discoverer/plus), I just write my right server name:
Example
After the installation of the Discoverer 1og server, into the httpd.conf file it was written automatyically: ServerName gnvdev
I just modified in ServerName gnvdev.ote.gr and both Viewer and Plus started to work perfectly at the first time.
I hope that this hint will be useful for you and others in the Discoverer forum !!!
Best Regards
Alex

I purchased holiday add-ons for the UtiliTap Week Calendar. I wanted basic holidays. Once added my calendar was flooded with listings for holidays, the majority obscure, repeatedly listed. The "hide calendar" would work only till the next time I opened it. These holidays were listed on the built-in iPhone calendar as well as the UtiliTap Week Calendar. I actually want to delete the two purchases because I tried deleting the UtiliTap Calendar (where I purchased the add-on holidays) and the holidays still showed up on my built in iPhone calendar.

My iPhone 4s has tured off and will not turn back on I have only had it a week it has been in the Otter box case the entire time. What do I do to get my phone back on??????

You can try to press the home button and power button and hold them for around 15-20 seconds. This will perform a soft reset similar to pulling the battery. If that doesn't help you may need to restore it.

It should be within a few days, but it might vary a bit by bank/provider :
I am in India, if the bank don't refunds , what to do?
Rajagopal.pngr :- It is only a holding charge, it is not a permanent charge. If it isn't refunded within a few days or so (and it quite possibly won't be over a weekend) then you can query the charge with Apple.

Can widget be made in a way that allows it to be running the entire time a particular ibook is open?

Functionality would require that a widget be running the entire time an ibook is open, not just while it was the particular page with the ibook.
If there is any way to have this sort of functionality, even if it isn't a widget I haven't been able to find any documentation about it.
Help would be appreciated.

Actually for the purposes of data tracking, trying to collect useful user data. Which would just need to collect user actions in the ibook.

Execute 4 jobs at the same time

Hello guys,
Is it possible with DBMS_SCHEDULER to execute 4 jobs at the same time. I'd like to use DBMS scheduler to refresh 4 different materialized view at the same time. After that, I'd like to start another job if they refreshed correctly.
So, can this be achieved?
Thanks for your help

It can be achieved using a chain job. Here is how you would do it:
Call DBMS_SCHEDULER.create_program to create 5 programs corresponding to the 4 MV jobs + the one extra job.
Call DBMS_SCHEDULER.create_chain to create a new disabled chain.
Call DBMS_SCHEDULER.define_chain_step to create 5 chain steps corresponding to the 5 programs you created earlier.
Call DBMS_SCHEDULER.define_chain_rule to create 3 chain rules:
-- Rule1:
condition => 'TRUE'
action => 'START step1, step2, step3, step4'
-- Rule2:
condition => 'step1 SUCCEEDED and step2 SUCCEEDED and step3 SUCCEEDED and step4 SUCCEEDED'
action => 'START step5'
-- Rule3:
condition => 'step5 SUCCEEDED'
action => 'END'
Call DBMS_SCHEDULER.enable to enable the chain.
Call DBMS_SCHEDULER.create_job to create the corresponding chain job of type chain.
Hope that helps.

Firefox's history only remembers the last time a certain web address is visited.

For example, I visited www.example.com on Monday, Tuesday and Wednesday. Of all the 3 times, Firefox only remembers the visit on Wednesday. Because when I visited www.example.com on Tuesday, the history is renewed, deleting record of Monday; when I visit www.example.com on Wednesday, record of Tuesday evaporated.
So, no matter how many times I visit a certain web address, Firefox only remembers the last time. Is there a way to tweak Firefox to make it faithfully record history?
I'm not a native English speaker. I hope my poor English clearly describe the question.
Thanks in advance for your answers.

Firefox updates the History, because the website content get updated day to day.
so Firefox remain the last visit.
If you don't like the history or cookies.

If i stream for 8 hours at work and keep my screen on the entire time will it shorten the life of the screen

if i stream for 8 hours at work and keep my screen on the entire time will it shorten the life of the screen

The screen itself would not wear out, however the LED backlights that make the screen glow do have a limited life span and over time they will become dimmer and shift color somewhat. This however would take years to accomplish. You'll be replacing your phone before you have anything to worry about.

Dear apple, can you please tell me how to put my 'x' key back onto the computer properly without giving me an answer which will make me want to buy a pc like 'we WILL only replace the entire keyboard'?

dear apple, can you please tell me how to put my 'x' key back onto the computer properly without giving me an answer which will make me want to buy a pc like 'we WILL only replace the entire keyboard'?

My profile does say level 1 (0 points) quite obviously pointing out i am a noob at this, although i did try to correct myself in the previous responce to **macbook.
I am confused why you think i havn't answerd michaels question though. 'I assure you the keyboard or the joining parts aren't broken and if it isn't broken i dont feel the need to replace it. '- that was me in the first responce explaining why im not buying a new one, answering the very question he asked.

Why does the circle at the curser point keep running the entire time my computer is on?

I am new to the touch-screen computer. I notice that the circle keeps running the entire time my computer is turned on as if there is more info about to come up. Is this suppose to happen? I have no idea if this is normal for this particular model. Thank you.

Immediately the size window opens.
Which window? Please post a screenshot.
Is the tablet’s driver up-to-date?
Because now I have changed back to Painting and the pen behaves normally without the circle and size window.
So the issue is resolved?

How to execute only once the *copy* about LRF1 tcode ?

Hi Experts !
I duplicated the LRF1 tcode by ZLRF1 tcode with the main program SAPLZLRFMON (please see below).
I have an issue with the execution about the ZRLF1 tcode, normally the LRF1 tcode can be execute only once under the same warehouse number, but my transaction ZLRF1 can be execute by more than one user at a time. I debug the execution about the ZLRF1 with a breakpoint set into LZLRFMONF01 include (include test connection) but the system excute the transaction without regard to the breakpoint set into LZLRFMONF01. Did I forget anything ?
thanks in advance for your help.

Yes - Standard SAP programs quite often check the program name and transaction code being executed. If you look at program SAPLLRFMON, you'll see that it uses both the program name and transaction code (LRF1) in a number of places. You have to go through your copy, looking for these places and add the logic for your trasnaction code an program names.

Execute several workitems at the same time

Hi everybody, we are implementing the Release Payment Funcionality, but due to a big volume of workitems it's necessary to execute a lot of workitems at the same time.
I mean, we manage 3000 workitems per week and all of them follow a procedure in wich in some cases there is only one "Releaser", so he needs to release payments in a mass way.
Is it possible to do that??
Regards

If the Approval step is a User Decision, the Approver can first select all that he/she shall Approve or, all that he/she shall Reject, or whatever other options you configure.
Once selected, click on the "Execute" button found on the toolbar immediately above the list of workitems in the Business Workplace.
The Approver will then be presented with the User Decision for the first selected work item. Now, whatever choice he/she wants applied to this and all selected work items, they should click it.
Next, the Approver will be prompted with a question asking if they want the same choice applied to the selected work items that remain.
I don't suggest this method for all 3,000 at once, but in a pinch, for a few hundred at a time, it works pretty well.
Hope this is relevent...apologies if not.
