So I was playing with INet and downloading files and made a simple video downloader, or it can even be used for any file really.
Just follow the reference section in INet_Settings.ini , and then run the script.
Main Script <snip>
INet_Settings.ini URL - The target URL of the video you're trying to grab Data - This is the starting string, and ending string reference to look for the download URL itself. Settings - Only setting here currently, is the delay in which to wait for the file to download ### Reference for Start and End points for various websites <snip>
Credits to : https://www.autoitscript.com/forum/profile/31965-progandy/ for the URL Encode and Decode.
I have a problem with getting first 10 characters with a big txt file, about 50k lines. I only want 10 characters of each line and save it into another file. I tried to use Stringleft every line and save it into another file but it was really slow to do it. I tried to save it into a variation like $var=$var&stringleft($file,10)&@CRLF. It's faster but still really slow.
Can anybody help me with this
Thank you so much
(Edited from original. Please note that I AM NOT AN AUTOIT EXPERT. I write code using Autoit frequently but I am no expert, especially when it comes to I/O. So any remarks that start with "Why did you..." can be answered by referring to the first sentence. This project was done in Autoit because of an interface I built to display the data.)
Attached is a program and ascii input file I wrote to read stock price data, convert it to binary and then read it back into the program in binary. The goal was to show increased performance for reading the files in binary and provide a demo on how to read/write binary for int32, int64, double and strings for anyone who might find it helpful. The results on my PC show the following:
Time to read ascii file only: 456.981951167202
Ascii read & process time: 6061.83075631701
Binary write file time: 14787.9184635239
Time just to read binary file: 42.418867292311
Binary read and process time: 4515.16129830537
A couple things to note:
1) The 32 MB ascii file took 10x longer to read than the 15 MB binary file. Not entirely sure why. Both were read into a buffer.
2) The Binary write takes a long time but I made no effort to optimize this because the plan was to write this file one time only so I don't mind if it takes longer to write this file. I care much more about how long it takes to read the file because I will be reading it many times.
3) There was a modest gain in converting the ascii file to binary in terms of file size and reading speed.
So big picture... not sure it's worth the effort to convert the files to binary even though most of the data is numerical data in the binary file. That was actually surprising as I expected there would be more of a difference. Any ideas on how to get the binary data to read at a faster rate would be great.
May I know how to copy the first 10 characters in excel and paste it in the file explorer textbox? How to do? I know that you show use the StringLeft() function but I am not sure how to do. Please help me. Thank you!
