• How can I restart firefox with the same tabs and windows?

  How can I restart firefox with the same tabs and windows?

  It is not in the file menu or tools. I get nothing when searching for help. FF still knows how to do it, say to update extensions.

  I know that I can do by saving my session, coming out, reboot and restore the session but is there a single command to do this?

  Thank you. -David

  I have attached a screenshot showing how to select restore automatic session just above the setting of the Home Page where it says "When Firefox starts".

  With this set, you can restart Firefox manually out using the menu-

  • "3-bar" menu button > button "power".
  • (menu bar) File > Exit

  -and then restart Firefox.

  If you want a real reboot with a click of button, you can check something on the Add-ons site: https://addons.mozilla.org/firefox/

• How read datalog multiple files at the same time?

  Hello friends...

  can someone help me to show how read datalog multiple files at the same time?

  Here is the example of my case.

  I have 500 files in a folder. each file contains a waveform and its setting.

  and then I want to do a card spectral these files, because these files have been saved in the order.

  the point is to know how to read these 500 files at once? I made a program to read these files, but the program can read these files in one by one. So it is very uncomfortable to read 500 files one by one. can someone help me solve this problem? Thank you. I hope you can show me the program. Thank you again...

  Hi jojo,

  Well, in the range of functions daughter, you will find a function to list the contents of the folder. This allows to get the names of all the files datalog, and then use a loop FOR to read.

  No one is obliged to provide 500 names of files manually - that's why we use a programming language to let the computer do the stupid work

  Mr President

  If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

  My two fields are FLOW AND DR_NAME

  FLOW = ACCT_ID

  DR_NAME = ACCT_NAME

  I created with success of LOV for these fields.

  First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.

  How can I report these lov, it's that when I change my acct_id then acct_name also change

  I have these two tables

  CREATE TABLE "NOM"  (
    "ACCT_ID" VARCHAR2(7) NOT NULL ENABLE, 
    "ACCT_NAME" VARCHAR2(50) NOT NULL ENABLE, 
    "O_BAL" NUMBER(13,2),
    CONSTRAINT NOM_PK PRIMARY KEY ("ACCT_ID")ENABLE
     
     );
  CREATE TABLE "VOUCHERDET" (
    "V_ID" VARCHAR2(9) NOT NULL ENABLE,
    "LINEITEM" NUMBER ,
    "DEBIT" VARCHAR2(7) ,

  I have synced my LR my android mobile. Why the images in a different order from the catalogue on the PC and how can I get them in the same order?

  You can check the order of Lightroom Mobile synchronization.

  Click on the collection name and choose the last option to sort.

  It should be similar to this screenshot:

  

  Once you get to know Lightroom Mobile images sort order, you can set the same sort order on your desktop of Lightroom.

  Hi sindres79946597,

  Open Acrobat Reader DC, navigate to the Edit-> Preferences-> General-> uncheck "Open Documents in the new tab in the same window.

  Now, reboot your system, when you open multiple PDFs that all will open in a new window so that you can easily compare.

  select distinct gender, gender from your table
