• Find and replace the string function replaces line breaks when I only replaced spaces?

  I need to replace all instances of a space or a series of spaces to a line with commas (or tabs) multi string so I can throw in a worksheet.

  I use the regular expression [\s]+ and it works, but it is also to replace the end of lines (\r\n) too.

  How can I replace the spaces but leave the end of the lines intact?

  Right-click on the search string and to take '-' code display. Enter the space character (\s) correctly - you \\s right now.

  Could please help what is wrong in the code, I followed all the steps as stated in the guide, but the table advance, the problem starts whenever I click on the button Add a new row for the creation of new line.

  I couldn't understand what was wrong with the code.

  Thanks in advance,

  Suman

  Suman,

  A few points:

  1. Why do you call handleCurrencyChangeEvent in the event to add a line? Simply set the useful, likely of the values in the line it himself.

  ex:-instead of calling the handleCurrenyChange method, simply add the below lines inside the createDetailRow()

  dtlrow.setAttribute ("ExchangeRateTypeRender", Boolean.FALSE);

  dtlrow.setAttribute ("ExchangeRateDateRender", Boolean.FALSE);

  dtlrow.setAttribute ("ExchangeRateRender", Boolean.FALSE);

  2. it looks like you have on the field of the currency and that fireAction handleCurrencyChangeEvent action method is called, right?

  Instead of using dtlVo.getCurrentRow, use the code below:

  public void handleCurrencyChangeEvent(String eventRowSourceParam)
    {
    OAViewObject pvo = (OAViewObject)findViewObject("xxCurrencyPVO1");
    OARow row = (OARow)pvo.first();
  
    OAViewObject dtlVO = (OAViewObject)findViewObject("xxEcreditCardDtlVO1");
  
    //OARow dtlRow = (OARow)dtlVO.getCurrentRow();
    OARow dtlRow = (OARow)this.findRowByRef(eventRowSourceParam);
  
    String  currency = (String)dtlRow.getAttribute("CurrencyCode");    // NULL POINTER EXCEPTION
  
    if ((currency == null) || ("AED".equals(currency)))
    {
    row.setAttribute("ExchangeRateTypeRender", Boolean.FALSE);
    row.setAttribute("ExchangeRateDateRender", Boolean.FALSE);
    row.setAttribute("ExchangeRateRender", Boolean.FALSE);
    }
    else
    {
    row.setAttribute("ExchangeRateTypeRender", Boolean.TRUE);
    row.setAttribute("ExchangeRateDateRender", Boolean.TRUE);
    row.setAttribute("ExchangeRateRender", Boolean.TRUE);
    }
    }
  

  In the controller:

  if((ADD_ROWS_EVENT.equals(event)) && "AdvTblRN".equals(pageContext.getParameter("source")) )
  {
    am.invokeMethod("createDetailRow",null);
    am.invokeMethod("initPVO");
  } //**End Add Row Button**
  else if ("currCodeChangeEvent".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
  {
    String eventRowSourceParam = pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE);
    Serializable[] params = {eventRowSourceParam};
      Class[] paramTypes    = {String.class};
    am.invokeMethod("handleCurrencyChangeEvent",params, paramTypes);
  }
  

  3. Why do you call initPVO when it is clicked on the Add line? Are you calling not just in the PR?

  You could call it once in the PR and let. When you call it PR, you may need to remove the handleCurrencyChangeEvent of this method call.

  See you soon

  Today, I updated for Sierra and updated to the latest version of the Pages. Now I find that I am more able to select a line of text. When I try to do, I find myself with an insertion point where I stopped by selecting, but nothing is selected. This is a bug in the new version of pages or get my wrong settings?

  You use a Wacom tablet by chance?

  Solution: Press the shift key, just before stop selection. And Yes, that sounds like trouble in the Sierra.

           TO_CHAR(TO_CHAR(evt_date_return, 'SSSSS') - TO_CHAR(evt_date_fail, 'SSSSS') seconds

• With an average of a spectral waveform and view / save

  Hello world!

  I am currently on a University project that consists on the use of Labview to obtain data and spectra of atmospheric plasmas using a spectrometer Ocean Optics HR4000.

  After not not using Labview for almost a year, I managed to get most of my knowledge back and I managed to display the spectral waveform, that I expect to get. However, as this is a fairly simple design I get a lot of noise and I would on average it for a graphic display more smooth.

  I looked into a lot of messages from the forum, but I couldn't really find what I was looking for.

  I also had a problem when you try to save the data and Spectra: I can't find anything in the directory of my VI.

  In the attachment you will find the current VI I'm trying.

  Thanks in advance for your answers!

  Jeremy

  I wrote an example for you below. This is an excerpt from VI, so you can drag the .png in your diagram and it becomes code. Pretend that everything in the green box is your Subvi spectrum acquisition.

  -Place the Subvi in a loop to run as many times as you like on average there

  -Out of the loop For is a table 2D with individual spectra on the lines

  -Transpose output, so individual spectra on the columns

  -Enter the table another loop to take the average rank by rank (with an average of different Spectra togeter).

  -Output is 1 d spectra average table

  

• With an average of lines in a multidimensional array

  I have a file (file1.dat) that is created using the 'write on the worksheet file vi', that writes the output of a photo detector. Experience a try N. Each test gives a table 1 d M number of data as a column. Once the experience complete, the file will contain N columns and rows of Mr. I'd like to find the average of each line in labview. The output (file 2.dat) should be a column of M elements, each element being the average of the N data contained in one line. Treatment in excel or origin is not possible. Generally, > 10000 and N > 100 M. Can help? For example:

  file 1.dat:

  A1 B1 C1

  File 2. dat must be:

  Follow these steps to try to solve your problems of boot.

   

   

  Restore point:

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   

  If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  Link above shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use:

  http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

  ISO Burner:http://www.snapfiles.com/get/active-isoburner.html

  It's a very good Vista startup repair disk.

  You can do a system restart tool, system, etc it restore.

  It is NOT a disc of resettlement.

  And the 32-bit is what normally comes on a computer, unless 64-bit.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  Data recovery:

  1. slave of your hard drive in another computer and read/save your data out there.

  2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

  3 Alternatively, use Knoppix Live CD to recover data:

  http://www.Knopper.NET/Knoppix/index-en.html

  Download/save the file Knoppix Live CD ISO above.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  http://isorecorder.alexfeinman.com/isorecorder.htm

  Download the Vista software from the link above.

  After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

  Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

  Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1^st in the boot order.

  Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

  When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

  Click on the icons of hard drive to open and to understand which drive is which.

  Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

  Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

  See you soon.

• Find and replace it with an invalid Code in Dreamweaver CC 2015

  I have a HTML file of 800 line with about 200 H3 tags not closed I want to remove. I try to use search / replace, but it doesn't seem to be able to find non closed tags.

  In the excerpt below, I want to remove or delete the H3 tag:

  …

  < /ul >

  < /li >

  < h3 class = "best_SubCategory_Title" id = "455474Title" >

  Best sedan

  < ul class = "ssMatchup_Entries" id = "Matchup455474Entries" >

  < /Li > < li > agreement

  Camry < li > < /li >

  Mazda 6 < /li > < li >

  Passat < li > < /li >

  < /ul >

  …

  I tried different ways, but Dreamweaver search / replace engine can't not find invalid or cavities not blocked tags?

  Here are a few things that I tried, and as you can see, Dreamweaver cannot find the H3 tag:

  

  

  If I close it manually one of the H3 tags, and then find and replace can find. I think I can use regular expressions to do this, but I need to understand this too, if that's the only way.

  What do you think? Any idea on how to get rid of 200 H3 tags not closed? Perhaps another application?

  Answered my own question, here is the solution:

  For some reason, Dreamweaver cannot find and replace invalid code, or at least it is not easy to do. My problem was that I had a H3 tag not closed and would not replace it. I had to first close the H3 tag, and then I could replace it.

  I did a find and replace the one sought a ">" followed by a lot of white space, like this:

  

  As my license to close the H3 tag, then I could easily find and replace all now closed H3 tags, like this:

  Hello

  because I have to show these values in the application.

  What is your problem then? If you simply issue a SELECT statement to application code or send the data back to REF CURSOR, it will be quite OK to have several lines. That's what the SELECT statements are for: to return sets of results with several lines.
  So, could not explain your problem more in detail please? If you get an error somewhere, provide the code causing the error and the error message (it is probably ORA-001422 exact extraction returns several lines somewhere in PL: / SQL, isn't it? then post here).

  In my opinion, the UNION is at the origin of the problem. Can I replace the UNION here? Please share your ideas on this.

  Us don't know not the answer to this question, because no one here knows your needs (what you need).

  I have this game were also up in a loop that says:
  
  < cfloop index = "help" list = "" #form.listofids # "delimiters =",">"
  
  Here is the code for just the insertion. I also have a code here
  Update another table. I got this to work, so I just try to get the insertion
  works fine for the moment. I can not use this where the query statement:
  Where ItemID = #id # because I'm trying to insert into the table of approval, not
  the items table. The table is just updated with some other info. in
  a few other input boxes.
  
  < cfloop index = "help" list = "" #form.listofids # "delimiters =",">"
  < cfif "form. "Help of # PNR_Approval_Initials #" NEQ "" > "".
  
  < cfquery Datasource = '#application. DataSource #">"
  Insert into accreditation (APV_ItemID,
  APV_ECID,
  Document_Type,
  Approval_Initials)
  
  Values (' #Evaluate ("form.) (' ItemID # help # ") #',
  ' #Evaluate ("form. ("ECID # help #") #',
  < cfif isDefined (form '. ') ("Help of # PNR_Doc_Type # ') and
  "form. "Help of # PNR_Doc_Type #" NEQ "" > "".
  ' #Evaluate ("form. ("Help of # PNR_Doc_Type # ') #',
  < cfelse >
  NULL,
  < / cfif >
  
  < cfif isDefined (form '. ') ("Help of # PNR_Approval_Initials # ') and
  "form. "Help of # PNR_Approval_Initials #" NEQ "" > "".
  ' #Evaluate ("form. (Aide de # PNR_Approval_Initials #») #
  < cfelse >
  Null value
  (< / cfif >)
  
  < / cfquery >
  
  < / cfif >
  < / cfloop >
  
  On the page display, just a table of dynamic info. Here are the 4
  things that I have on this page that needs to be inserted to the database.
  
  < input type = "hidden" name = "' ECID #ItemID #" value = "#ECID #" > "
  < input type = "hidden" name = "' ItemID #ItemID #" value = "#ItemID #" > "
  < input type = "hidden" name = "" PNR_Doc_Type #ItemID # ' value = "PNR Req" > "
  
  < td align = "center" >
  < cfif Approval_Initials is not "" > "".
  #Approval_Initials #.
  < cfelse >
  
  < select name = "PNR_Approval_Initials #ItemID #" >
  < option value = "" > select initials < / option >
  < cfloop query = "ShowInitials" >
  < Cfif Engineer_Initials EQ 1 >
  < option value = "#Initials #" > #Initials # < / option >
  < / cfif >
  < / cfloop >
  < / select >
  
  < / cfif >
  < table >
  
  Can someone help me please on just the insertion in the database so that it
  will insert on the lines that I chose the initials on and not others? Thank you.

  You almost managed, but I see that you have commented.

• Lexical in several lines and all parameter headers print in PLSQL

  HI team,
  
  I have some requirement in plsql can someone please help with solutions.
  
  1. print the headers on several lines in pl/sql block using the dbms_output
  I have some column FILE_name, creation_date and so on, I want to print multiple line headers
  
  ex:_
  
  Creating files
  Name Date
  -------------------------------------------------------
  xxd_top.txt June 10, 2009
  der_top.txt August 21, 2009
  
  2 using the lexical in plsql block in the cursor as parameter
  
  ex:*
  
  cursor c1 (p_parameter)
  is
  Select * from EMP
  where & p_parameter
  
  and I'm assigning the value of p_parameter in the begin block.
  When compiling I was getting error when compiling.
  
  Please give me some suggestions to solve these problems
  
  Thanks in advance
  Sriram

  If you want to only several lines of DBMS_OUTPUT then call DBMS_OUTPUT. Put_line several times. I'm guessing that you want this layout:

  File        Creation
  Name        Date
  ----------- ------------
  xxd_top.txt 10-Jun-2009
  der_top.txt 21-Aug-2009
  

  The simplest approach would be just something like

  DBMS_OUTPUT.PUT_LINE('File        Creation');
  DBMS_OUTPUT.PUT_LINE('Name        Date');
  DBMS_OUTPUT.PUT_LINE('----------- ------------');
  

  I tried with CHF solution and it worked.

  Post an example of what you have tried that does not work, maybe someone will see what is wrong with it.

• Why most of the tabs open empty with the label "New tab" and "topic: vacuum ' in the address line to the restart of Firefox since installing Firefox 28?"

  I have a system dual-bootable Windows Vista SP2 and Firefox updated to 28 on both systems. Since the update of the tabs more reopen empty with the label "New tab" and "topic: vacuum" in the address line of Firefox is restarted. The tabs that open correctly seem to be those who in fact, I was at the session of prefious. I can recover the missing tabs using the Session Manager to pick up a previous session, but of course it does not pick up the tabs open in future sessions. It seems that the tabs that I go to the session recovered are saved correctly, as indicated above, but which are not revisited in the context of the use of the session retrieved will drop the URL next time that I open Firefox it again.

  jdgale:

  I don't have the time to do it. However, 29 is just around the corner and we will put in the channel of exit 29, then hope that the issue is not you.

  P.S. I had originally chosen your last answer as the solution that you have migrated more to 29 but it seems that you have taken off. I'll be marking your last answer as the solution so that we can get out of the queue.
