Disable an element in the creation of new line

I have a table with a column that contains a button to print to open a print page to print the associated line. Now, when I press the new button to add a new row to the table I want to disable the button "print" which is in the same row (because there is no line to print yet) and allow him, after the user saves the new line. How I do that?

Yes, you can use the following Boolean expression:

#{pageFlowScope. [groupName] Table.newRow}

  • How to transfer the text value of the element with the character of new line between pages?

    Hello

    I use the Application Express 4.2.2.00.11 on the 11g XE database. In my application, I use the transfer of certain values deposited between pages on a lot of places in my application. But now I have a specific problem with a textarea element.

    I have the page with the textarea element and I transfer element value to another page using the link button. I use "Set these elements" "with these values" mechanism.

    Everything works fine until I try to add the new line character in the area of the text box to be transferred to another page. I get this error message when I try

    Contact your administrator for the application. The checksum calculated on the basis of the application, clear the cache, names of arguments and argument values (711P711_TEXTabc CRC [A55D4D4B325E23CB83EF28FB7671E8F0]) does not match the checksum passed to the procedure of show (23CC724ADDA630B6F3BDFD2FEE1498E0). Note: users receive a different error message.

    Transfer of value to another implementation of page when I 'abc cde' in the text box.

    Transfer of value to another page do not work when I 'abc [line break] cde' in the text box.

    Value of transfer with the new line character point works when I change "Arguments must have checksum" "Unrestricted" on the landing page. But I want to use the shared services provider and do not want to disable checksum calculation.

    It seems that there is a bug in the function of calculation of sum of internal control...

    You have some tips?

    This is one of the many reasons why it is inappropriate pass strings of characters between the pages through the URL. Instead of using a redirect button, change the button to send the page, then use the conditional calculations to set the values on the landing page and finally access the page using a conditional on submit: before Validation: (after calculation and before Validation and treatment) branch. When you press button terms of use on the calculations and the direction.

  • Prevent the creation of new user accounts in Vista

    Is there a way to prevent the creation of new user accounts in Windows Vista? What about restricting internet access to all new account that is created? Help! :)

    Hello

    If your contact is logged on as administrator, then he or she can create a new user account. If you don't want someone else to create a new user account, you can then create a standard account for them, in this way, they will not have the privilege to create a new user account.

    Create a user account

    If you don't want to give them access to the internet, then you can use the parental control.

    Set up Parental controls (Vista)

  • How to remove the character from new line at the beginning of the attachment?

    Hi all

    I tried to attach a .dat file that is generated to an external source and send it as an attachment by e-mail with UTL_SMTP, all things work, but the .dat file that is attached in email contains a new line that is Chr (10) on the start line and the content of the file is written to the second line from.

    I remember correctly, a single empty line serves as a separator between the header Mime and Mime body.

    Copy the following code...

    UTL_SMTP.write_data(c,
      '-------SECBOUND' || UTL_TCP.crlf ||
      'Content-Type: text/plain;' || UTL_TCP.crlf ||
      ' name="/inetpub/wwwroot/Novation_Merge/FS_Extract.dat"' ||
      UTL_TCP.crlf ||
      'Content-Transfer_Encoding: 8bit' || UTL_TCP.crlf ||
      'Content-Disposition: attachment;' ||UTL_TCP.crlf || ' filename="' || p_description ||
      TO_CHAR(SYSDATE, 'DD-MON-YYYY') || '.dat"' ||
      UTL_TCP.crlf || UTL_TCP.crlf ||UTL_TCP.crlf);  
    

    .. generates 2 blank lines after the Mime header.

    Delete the last CRLF and see if this fits the Bill.

  • ADF: how to insert the character of new line in the column of VO?

    Hello world

    IM using Jdev 11 G.
    I have a VO with 5 columns appear on the page of the ADF. (VO a total 8 columns)
    column 1 is the combination of 3 columns. I concatenated 3 columns and add the new line character after each column Chr (13).
    VO query works very well as a toad. the columnn displays each column value concatenated after a newline character, but the same query does not work in the ADF.
    The column that is the concatenation of the 3 columns and should display with the new line character does not display the new line character its just concatenation of the 3 values and display on the page.

    Wat could be the solution for this in the ADF?

    Thank you.

    Column does not have the property to escape. It is part of the output text.

    Something like

  • Export of string in csv format, keeping the commas and new lines

    Hello

    I export the string to the csv format and have been removeing of new lines with commas as so

    thing.toString ().replace(/\n/g,_'').replace (',', ");

    How can I make this iwthout lose line breaks and commas? I can't have in atm as mess up the csv file.

    JSON is more 'transfer' information that can be gathered in number, string, array, object, etc format later.

    Excel can import CSV, but it cannot interpret the complexity of the information. Typically what you would do is serialize complex information with JSON, receive on the other side (where it is perhaps) and then to deserialize. After you are deserializing it using the capabilities of JSONs to put your information into what is was (numbers, strings, arrays, and object) it is up to you how you restructure the data to the format of your choice.

    Your original intent of preserving CSV is the best for Excel or OpenOffice Calc. You don't mention your intention. JSON would package these \n's (CRLF) for you.

  • Problems with the creation of new samples

    Hello

    I seem to have huge problems with get newly created real, etc. in my palette of shades. To be as detailed as possible about this problem I will inlcude the two links that I tried to follow along.

    http://www.Suite101.com/content/creating-pattern-fills-in-Adobe-Illustrator-a74636 -a simple guide to create new patterns of filling to ensure that I do not have anything wrong.

    http://www.vectordiary.com/Illustrator/bling-bling-text-effect-tutorial/ -guide of what I'm trying to do

    I am relatively new to this program so I could be overlooking something, but I'm sure I was as complete as possible with it. Every time without fail I have my bounding box invisible sent to the back layer more remote with no border or background, then drag it to my Swatches palette, that nothing is happening. I can drag in the symbols but that's all, nothing happens. Maybe is something that these tutorials have missed? Or I have to (I'll try and make as much sense here as possible) cut and remove all the model outside of the rectangle enclosing invisible (which I sent to the farthest back layer) and group them before dragging them from the palette of nuance? I use Illustrator CS3 if that helps at all.

    Any help would be much appreciated, it's driving me crazy

    This be added to your new swatches so quickly that you don't notice yet it is at the bottom of your color chart (scroll down).

    Looks like your boss is tracks filled with a gradient, so if this is the case you will not any offending items. Do a test by drawing a shape(eg: star) and this dragging to the Swatches palette, if it creates a mosaic of model that you probably have a faulty element within your original selection (for example: linked picture)...

    I would like also in color chart context menu choose > select unused nuances and delete those, so your progress can be better monitored.

  • Best practices for the creation of new library system

    I want to create a photo library second, named Photo library - offline (for example) that is not synchronized with iCloud photo library.

    Am I right in thinking that once I've created the new library and set it as the photo library of the system, it will be synchronized with ICPL and import all photos of ICPL new library?

    Am also right in thinking that, once all the ICPL photos are synchronized with the new library, they will remain in the library named library Photos - Offline, even though I unchecked it as the SPL?

    Or I have to export all the photos of ICPL to the HD on my Mac, and then import them manually to the new photo library?

    Am I right in thinking that once I've created the new library and set it as the photo library of the system, it will be synchronized with ICPL and import all photos of ICPL new library?

    Yes.  The new empty library will start to download photos from iCloud library after enable you it as a Photo library system in Photos > Preferences > general and like iCloud photo in the photo library > preferences > iCloud.

    But wait, that all the photos of the old library were transferred to iCloud and the iCloud watch Preferences tab is no longer a progress bar.

    Am also right in thinking that, once all the ICPL photos are synchronized with the new library, they will remain in the library named library Photos - Offline, even though I unchecked it as the SPL?

    Yes, the switching between libraries will not remove photos from the library.

    A few comments, just in case where; If you want to sync a library with iCloud is not on your system drive, make sure, that the ths disk is formatted as Mac OS extended (journaled =, or it cannot be used as a photo library iCloud.)  Do not download thumbnails of faces to iCloud photo library.  If your second copy on the external hard drive will not be showing any thumbnails of faces that you have assigned.
