Please help me, i have 2 projects in this file
same thing happen with me my project work file I saved but when I open it in morning it not opening their size become 0kb. showing error “Error loading notebook” following steps to recover that file that i did and i get that file.
step 1) open the file explorer/my computer.
step 2) from windows explorer "view tab" click on show hidden file.
step 3) goes to that folder where you stored that jupyter (.ipnb) file.
step 4) when show hidden file option enable then you see you jupyter file
but in hidden format you need to rename it by just remove " . "
dot from its name and rename it and save.
Ex.file name is ".LSTM model" then rename it by removing dot(.)
before file name and give name " LSTM model "
step 5) now this rename file is open from jupyter notebook.
(Note: actully jupyter file backup store in hidden format in windows if we enable show hidden file from window explorer we can rename and reuse file which is corrupted)
I need to repeatedly extract contents from a large number of text files with addresses given by URLs. Every time I run my R code and connect to a file it opens in Notepad++ which is my default text editor. The R code alone works perfectly well but in the text editor I have a "Reload" dialog window for each of 100+ files. How can I avoid this?
I use url.show function to extract the text and file function to connect and read the data.
url.show('https://www.playok.com/p/?g=gm136365880&txt', file='game.txt')
con = file("game.txt", open = "r")
### some code: extracting lines of text and processing...
close(con)
Probably these are not the proper functions for my particular task. What I need is just a connection to the file contents without opening the file anywhere (including my RStudio window and the text editor window).
If you don't need a local copy of the file, you can just pass the URL to open:
con <- file("https://www.playok.com/p/?g=gm136365880&txt", open = "r")
readLines(con)
close(con)
will print the content of the URL

I write VBA code in Microsoft Office PowerPoint for you. You can achieve to your goal with this code.
You must create a text file with name "Info.txt" in following order when you want to create a PowerPoint presentation (path of the text file must be in where you have placed my attached "InsertPicture-Office 2007.pptm" and "InsertPicture-Office 2010 & 2013.pptm" files):
Line 1. Distance of the image from Left of the slide
Line 2. Distance of the image from Top of the slide
Line 3. Image Width in the slide
Line 4. Image Height in the slide
Line 5. Full path and name (with extension [.pptx]) for saving PowerPoint presentation file
Line 6. Full path and name (with extension) of an image for inserting in the slide of the PowerPoint presentation
After save the text file, you only must run the "InsertPicture-Office 2007.pptm" or "InsertPicture-Office 2010 & 2013.pptm" file and everything will be done.
Remember that you must "Enable all macros" for Microsoft Office PowerPoint from following way:
Open Microsoft Office Powerpoint -> File -> Options -> Trust Center -> Trust Center Settings -> Macro Settings -> Enable all macros ...
4Shared -> InsertPicture-Office 2007.pptm, InsertPicture-Office 2010 & 2013.pptm and Info.txt files
SendSpace -> InsertPicture-Office 2007.pptm, InsertPicture-Office 2010 & 2013.pptm and Info.txt files
You can test it only with change "Info.txt" file in order of what I'm mentioned above, and opening one of the "InsertPicture-Office 2007.pptm" or "InsertPicture-Office 2010 & 2013.pptm" files according to installed version of the Microsoft Office PowerPoint in your system.
