Lua help. Download file from my url and save the file where my .exe trainer is located.
My .exe trainer located at D:\downloader
and i run my .exe trainer.
For example, i click "Download Now" button,
the file should download from my url and save the file in D:\downloader
Thank you so much!

You must reference the LuaSocket library and with that you can use this snippet to download a file from a specified URL.
| Code: |
-- retrieve the content of a URL
local http = require("socket.http")
local body, code = http.request("link_to_file.exe")
if not body then error(code) end
-- save the contents to a file, wb is used to set the flag for writing the file in binary mode
local myfile = assert(io.open('name_of_file.exe', 'wb'))
myfile:write(body)
myfile:close()
|
The LuaSocket library can be found here:
github.com/LuaSocket
Edit: Apologies. DB has pointed out the getInternet function in the celua.txt document. I wasn't aware of this function.

Thanks. But this confuses me a lot.
Is there any way without using luasocket?
my url link is only a table.CT file and saving it anywhere in my desktop is fine.
I hope there's a simple lua code.
sorry, my english sucks

You can use it like this:
| Code: |
local ic = getInternet('inet').getURL('url_to_cheat_table')
if ic ~= nil then
local myfile = assert(io.open('path_to_file.CT', 'w'))
myfile:write(ic)
myfile:close()
end

If you're still in this code, let me expand on the topic with some explanations.
-----------------------------------------------
The main code is here:
@Zanzer: https://forum.cheatengine.org/viewtopic.php?t=597759
-----------------------------------------------
1) Make sure the URL will download the current trainer.
2) Upload your updates to a site that will always use the same URL.
3) Define a path for the current Trainer.
| Code: | | local path = TrainerOrigin or getMainForm() |
4) If you are going to download the new version to a different location, identify it as well.
| Code: | local path1=[[D:\downloader]]
local name = path1 .. "\\" .. newName |
5) Create another url for version test and Trainer name.
| Code: | local versionNum = 0
local ExVersion = 01
local newName=""
UDF1.CEButton1.Caption="Download"
local path = TrainerOrigin or getMainForm() --Ex Trainer path..
local path1=[[D:\downloader]] --New Trainer path..
function loadUrl(link33)
local int=getInternet()
s=int.getURL(link33)
int.destroy()
return s
end
function VersionCheck()
local result = loadUrl("https://docs.google.com/document/d/1_Px-WKrnyw8MsqmwJnz2__eufO6cey653n77VZTDEok/export?format=txt")
local SL1 = createStringlist()
SL1.Text=result
for i=0, strings_getCount(SL1)-1 do
versionNum=SL1[1]--:sub(1,9)
newName=SL1[2]
versionNum=tonumber(versionNum)
ExVersion=tonumber(ExVersion)
end
SL1.destroy()
if versionNum==ExVersion then
UDF1.CEButton1.Enabled=false
else
showMessage("There is a new version.\nClick the 'Download' button to download!")
UDF1.CEButton1.Enabled=true
end
end
VersionCheck() --Open Trainer.. Execute func..
local name = path1 .. "\\" .. newName
function TrainerUpload()
if syntaxcheck then return end
local TABLE_VERSION = tonumber(ExVersion)
local table_url = "https://docs.google.com/uc?export=download&id=1d-lCWA1fAEpkPDTxvjGu4dxgNSRCj1E0"
local http = getInternet()
local version = tonumber(versionNum)
if version > TABLE_VERSION then
local answer = messageDialog("There is a newer version of this table.\nWould you like to download it now?", mtWarning, mbYes, mbNo)
if answer == mrYes then
messageDialog("Caution:\nThis update will permanently delete the old version.\nIf you do not want to delete the old version,\nget a copy before you approve!", mtInformation, mbOK)
local latest = http.getURL(table_url)
if latest ~= nil then
local file = io.open(name, "wb")
file:write(latest)
file:close()
local name = os.execute(name, "\\"..newName);
--local file = os.remove(ExName)
--closeCE()
loadTable(name)
else
messageDialog("Failed to load the new table!", mtError, mbOK)
end
end
else
messageDialog("You currently have the latest version!", mtInformation, mbOK)
end
--else
-- messageDialog("Failed to find latest version!", mtError, mbOK)
--end
http.destroy()
-- int.destroy()
assert(true)
end
UDF1.CEButton1.OnClick function()
TrainerUpload()
end |
Note: For ".exe" files, remote invocation may fail due to possible security errors in the installation and run procedures. My recommendation; Use the above code with ".CT" or ".Cetrainer".
