Author Topic: Huge FTP Library for Windows (WinAPI) (Read 8109 times)

SpriggsySpriggs · « **on:** November 17, 2020, 06:50:05 pm »

Since this library is so huge it kind of deserves its own post (Literally used every FTP function available in Wininet except for FtpCommandA). Yes, I have been a little quieter on the forum recently but that's because I've been working behind the scenes trying to find my next big project. Well, I've found it. FTP using WinAPI. This took me several days of working night and day and staying up until 4, almost 5 AM. This library provides many possibilities. You can change FTP directory, create a directory, upload a file, download a file, delete a file, rename a file, and delete a directory. Also, a nice feature; you can generate a "CMD dir" style FTP listing that gives last modified date, file size, and file name (Now with extension filtering! Woot! Also, added a function that returns a file listing as a string using an extension filter). Uploads and downloads can be tracked with percentages. In the library, I've designed it so that the screen is cleared and the progress is printed as it does either of those commands. Obviously, one could comment those out if so desired. There is the option of uncommenting the FtpGetFile and FtpPutFile functions if you don't mind your program taking a pause to upload or download something large with no way of tracking the progress. It's up to you. Here are some screenshots showing a couple of FTP listings. Directories show as bright green.

And the code:

Enjoy! Let me know how you all like it and hit me with any questions you have... provided that you have actually read the post first before asking the question.
This should go without saying but in order to test this you will need access to an FTP server and use valid credentials.

Very interesting library Spriggsy, I'll dive into it deeper when back home from work.

And whoever is the owner of the FTP listed in your 1st screenshot seems to be a big K-Pop lover, just as I'am :)

@RhoSigma
Indeed :) (it's me)

SpriggsySpriggs · « **Reply #3 on:** November 18, 2020, 02:47:27 am »

Added the ability to filter the "dir" style directory listing by extension as well as a function that returns a directory listing as a line-feed delimited string that can also be filtered.

Screenshot showing the filtered list:

Nice! Im gonna dive into this when i get back home too. K-pop is so popular nowdays, many of my piano students ask to learn kpop tunes on piano.

Thanks for continuing the API work!

Question from NOVARSEG

SpriggsySpriggs · « **Reply #7 on:** November 19, 2020, 09:25:04 pm »

Another question from NOVARSEG:
https://www.qb64.org/forum/index.php?topic=3269.msg125485#msg125485

@NOVARSEG

InternetReadFile and InternetWriteFile are two entirely different functions. One is sending data to the FTP server and one is reading from the FTP server. Are you wanting to know about InternetReadFile or InternetWriteFile and what is it you are wanting to know? I want to help you but I have to know how.

NOVARSEG · « **Reply #8 on:** November 19, 2020, 10:41:58 pm »

In the line
****
PUT #1, , outputfile
****
how does PUT know how many bytes to write to the string?

the string was DIMed like
****
DIM outputfile AS STRING
****

PUT doesn't write to the string. It writes the string to the file. PUT is a file operation. It simply takes however many bytes the string is and writes it. It doesn't care how large or small it is.

NOVARSEG · « **Reply #10 on:** November 19, 2020, 10:51:39 pm »

whoops again did not see the

****
OPEN destfile FOR BINARY AS #1
****

sorry

what does this do?
****
outputfile = MID$(buffer, 1, dwRead)
****

why a mid$ and not a left$

I thought **** outputfile = LEFT$(buffer, dwRead) ****

in case dwread < LEN(buffer)

I simply am grabbing the number of bytes (dwRead) from outputfile because the string is actually much longer than the actual data. If I don't grab the string up until dwRead then the string contains junk data from elsewhere on the computer. Your graphics card info, a random word, etc. I prefer MID$ (I detest LEFT$ and RIGHT$) and use it often. I use it in many places in my WinAPI projects and so I keep using it for consistency. dwRead is the return from the FTP server. It will most likely always be less than LEN(buffer). The buffer is supposed to be larger than what I expect. Also, NOVARSEG, when you keep editing your posts when I am replying it makes it difficult to keep up with you (except now I realize you don't know that I'm replying when I am which is why it would be great if you join the Discord server hint hint).

NOVARSEG · « **Reply #12 on:** November 19, 2020, 11:19:47 pm »

That is interesting about LEFT$ and MID$

MID$(buffer, 1, dwRead)

and

LEFT$(buffer, dwRead)

should compile the same way.

sorry for the edits. email is worse though

SpriggsySpriggs · « **Reply #13 on:** November 19, 2020, 11:23:13 pm »

@NOVARSEG Well the Discord server is an instant messaging platform.

I know LEFT$ would give me the same results as MID$ but like I said I just prefer it, use it more often, and want to keep up consistency. I'm going to sleep soon so if you have any more questions then I probably won't answer them until tomorrow afternoon.

I would like to try your program. Looks pretty solid. A lot can be done with FTP library.
