FTP Download and scope...

Submitted by locke on Mon, 2015-09-14 09:07

Hi Guys, It's been a long time since i needed your help, but i'm stuck with a scope issue for my license script.

I'll Try to explain:
- I've got a mse file, with a few critical functions and a variable into.
- The script download the file into a specific folder,then i call "FileIn Thefile" and the next line is supposed to execute a function found into this file.
-If i launch max, and evaluate the script, the function is not found, but if i evaluate it a second time, the function is found and the script continue... A classic scope issue.

Here is the code:

--Download Usefull Function and execute from server
local targetfunction = ("RF_DecryptFunction.mse")
local tempfunction = (getdir #userscripts + "\RF_DecryptFunction.mse")
download targetfunction tempfunction
FileIn tempfunction
deletefile tempfunction
free targetfunction
free tempfunction

I've read about the difference between filein and include, but don't understand the main differences.

Once this part evaluated, i just want to use some functions i thought stocked into RAM (== Globals ? ) and free them right after.

Thanks.

Florent.

Hi, I know i don't have many replies regarding my issue with my download function.

In fact, i do this to protect the use of my scripts without my knowledge; I've had some bad experiences where once the script made, i'm gently pushed away from the company, and the client just use my work indefinitely. I need to protect my work for a future use, and i guessed that an internet check should be the easiest way.

Does anyone here knows a way to disable a script, or protect it from a non wanted use ?

Kind Regards,

Florent.

Finally Return

I corrected the script, i had to use Include instead of Filein, and it can smoothly read the functions into the mse File.

I had to use a literal expression so i use the C:/User/public folder.

But, i understand earlier that as you said, i'm having troubles for my download function;
I tried to understand the explanation from Jos Balcaen (http://josbalcaen.com/ftp-upload-maxscript/)

I just changed the UploadAsync for DownloadAsync... Maybe not a smart move. Here is my function: 

fn download externalfile localfile =
(
webClient = dotnetObject "System.Net.WebClient"
webClient.Credentials = dotnetObject "System.Net.NetworkCredential"\
"MYUSER" "MYPASSWORD"
theUri=dotnetObject "System.Uri" \
("http://ftp.[ADDRESS]"+ externalfile)
webClient.DownloadFile theUri localfile
)

Si into my script i have: 

--First Part
gc light:true delayed:true
--Download Useful functions and execute from server
local targetfunction = ("\\RF_DecryptFunction.mse")
local tempfunction = "C:\Users\Public\RF_DecryptFunction.mse"
download targetfunction tempfunction
--
 
--Second PArt
If doesFileExist "C:\Users\Public\RF_DecryptFunction.mse" do
(
try (Include "C:\Users\Public\RF_DecryptFunction.mse") catch (print "Damned")
)
--

If i just launch the full script, it crashed, the file is downloaded at the end of the script, not when i call it.

If i Launch the first, then the second, everything runs as i want to.

I don't understand much about the dot-net classes and functions. I may have a way to download the file, wait until it's done, and continue. But i don't know how to use the return from the dotnetobject...

Hi, thank you both for your

Hi,
thank you both for your replies.

I Just tried to copy the file into (getdir #userscripts + "\\RF_DecryptFunction.mse") to just execute the code without the downloading part. It Still Fails.

I tried to declare global vars into the Decryptfunction file:

global decryptmessage
global licencenbtodll
 
fn decryptmessage encryptedmessage refkey encryptionkey =
(
)
 
fn licencenbtodll = 
(
)
 
global refkey = #()

It Didn't work with FileIn.

I'll try to find some time to look the link Pixamoon posted.

Thanks,

Best Regards.

Florent.

.

To use the functions written in "RF_DecryptFunction.mse" you must knot the name of those functions. No matter if you use include or fileIn, if you don't know the name of the functions you can't use them.

`

hi,

first please use double "\\" in "\RF_DecryptFunction.mse" -> "\\RF_DecryptFunction.mse"

"\R" is a carriage return character

And your issue - I think it depends of download function. Maybe file is still locked after download and can not be started.

what you can do:
- download file to temp,
- wait till is downloaded,
- copy to correct location,
- delete temp file
- run by "filein" or "include"

to "include" script from custom location take a look here:
http://www.scriptspot.com/forums/3ds-max/general-scripting/include-funct...

also to run function by "filein" - I think function needs to be global eg:

global newFunction01
fn newFunction01 = 
(
   --...
)

than it will be visible by rest of your script

"include" should just include the function inside your code

Best,
Pixamoon
