I want to download a large number of .png files that have .htm file extensions. I've tried a some WinPcap-based utilities, but none of them pick up the files I need. The utilities I have tried are called York, EtherWatch and Pikachu2. I've also tried using a Firefox extension called Save Images - which was too buggy to be useful - and I've tried looking in the browser cache. This last approach works, but it has a problem...
...I need at least the last 30 characters of the file names to be maintained so that I know which image is which.
Does anyone know how I can get this done?
you can use downthemall to download all the images, and rename the file extension programmatically

I am currently working on a coding project and I am running into trouble with how i Should import the data set. We are supposed to have it read in a way so that our instructor can access our markdown file and be able to import the data and run the code without changing file paths. I know about using relative file paths to make it accessible to anyone, however I don't know how to get around the /users/owner part of the file path. Any help would be greatly appreciated and if you have any further questions feel free to ask.
I've tried changing the working directory to a certain folder that both I and my instructor have named the same thing, however, like I said above, when I use read.csv to import the data frame I am still forced to use the /users/owner filepath which obviously is specific to my computer.
I can understand your supervisor, I request the same from my students. My recommended solution is to put both data and R script (or the .Rmd file) in the same folder. Then one does not need to add a path in the read.csv (or similar) function.
If you use RStudio, move to the folder in the Files pane and then use the gear icon and select "Set as Working Directory".
Then send both files (.R or .Rmd) and the data to the supervisor, ideally as a zip file. The supervisor can then unpack it to an arbitrary folder and just double click to the .R/.Rmd file. The containing folder will then automatically become the working directory.
Other options are:
to use a subfolder for the data or
to put the data to a publicly readable internet location, e.g.
Github and read it directly from there.
The last option requires of course that the data have a free license.
I am using a quite unknown bookmark manager on Android. I picked this one after trying others because it was possible to import, export, classify by folders, the design was good and it was easy to search in my bookmarks.
After importing all my bookmarks from other browsers and also from files, I started classifying all of them into folders, subfolders, etc..
I spent many days to classify them all as I wanted.
After classifying them, I tried to export them.
The problem is that the only option offered is to export them in a .html file, containing all the bookmarks but without any folder.
The .html file contains all my bookmarks but in complete desorder, and doesnt mention the folders.
In the app there was also a "backup" function, so I tried and it creates a .db file.
I opened this .db file with some SQLiteViewer app and I found written inside, among other things I dont understand, a list of all my bookmarks with a number next to each one of them, and also a list of my folders with next to them the corresponding number.
When I open the .db file, I have a choice between
-SQlite master
-android metadata
-bookmarks
-folders
-sqlite sequence
If I click on "Bookmarks", all my bookmarks are in a kind of spreadsheet with lines and columns. Next to them in another columns, for example for each bookmark related with "Kitchen recipes" it's written the number 1.
And in the "Folders" folder, next to the folder called "Recipes" its also written 1.
So I'm happy because it seems that my classification is stored in this file.
But the fact is I dont know how to extract easily all that data, and create with it a "bookmark" file importable in other bookmark app or browser ( for example .csv or .xbel or .html but with folders)
I guess I need some "script" working like this:
if the first raw in "Folders" got the number 8 next to it
Then take all the bookmarks in the "bookmarks" folder that also got an 8 written next to it, and put it inside this folder.
I'm a complete noob in coding, I dont know what is SQlite, nor anything.
So i know that maybe I am asking for too much informations at the same time.
But if some kind person could put me in the way, by explaining me if
thats possible
what would be the easiest way
if some solution already exist
if someone like me can do it and what do I have to learn if I want some day to be able to do it
Thanks
Here's pictures so you understand easier:
Sqlite
Folders
Bookmarks
I've written an Extension that, among many other things, renames files based on the Types they contain.
This works fine for files in the directory-tree under the csproj-file -- I find the ProjectItem entry for the file and change its name.
For 'linked'-files (those not in the directory-tree) I can rename the file (via File.Move()) but haven't found a way to programatically modify the csproj-file (after the rename the csproj-file has to be modified manually).
If this is something that can be done I'd appreciate a pointer to the docs showing how to implement the functionality.
The easiest solution for me was to modify the csproj-file.
Open, read whole file, close.
Verify that file I want to rename (e.g. xxx.cs) only occurs in 1 directory
(if it occurs in multiple directories the change has to be done manually.)
Make change
Open, write whole file, close
For an SDK project the change is applied immediately.
For a non-SDK project the change is applied after responding to the prompt that the csproj-file has been modified.
I need your help over a problem I have. Actually, I have a page with a simple embed which displays a PDF file.
I got a request to add another PDF file to the same embed (or at least to do something which would look like it).
I searched some solutions and not finding a simple one, I'm thinking about using iTextSharp to merge both files (by getting their stream from their url), merging them into a new pdf file and display this resulting file into the embed.
But I'm just telling myself it's a bit too much for such a simple modification... And so I'm here asking you if someone would have a better idea ? From what I searched on stackoverflow and google it looks like I will have to take the merge solution but hey, we never know '^^
A simpler option would be to merge the two PDF files using either a free online tool or Adobe Combine Files option and then adding that newly combined PDF to your site. Unless I am missing something, there is no real reason or benefit to do this using code.
I am writing a web app, and not sure about how to upload multiple images. I want to make sure that either all images are uploaded successfully, or none of them.
One way is to upload them simultaneously in several thread. However, if one of the uploading process fails, it is difficult to cancel other process and remove uploaded images.
The solution I come up with is to combine the multiple files into a bigger file using some separator, and then server then separates it into original files.
Is my solution appropriate? Or are there any better solutions?
You will need some functional to check all files after all files have been uploaded. The simplest way - using standart form/multipart POST with all files in one request. But of course it is not so elegant. Another way - using one of popular and well tested plugin, for example - https://github.com/blueimp/jQuery-File-Upload
