How to build a simple "CHECK FOR UPDATE"?

[jassing]

My spidey sense was tingling that you'd ask for code...

There are two methods that work -- one is the Globalpaths plugin -- however, I had some errors with it -- and why include another file in your project, when a few lines of code will do it -- drop this into your "Global functions"

function System.LaunchFolder()
  local cProgramFolder = _SourceFolder;
  if Table.Count(_CommandLineArgs) > 0 then
    local x;
    for x=Table.Count(_CommandLineArgs),1,-1 do
      -- The SFXSource is always at the end/last -so we look there 1st -- however, it's not specified in the docs
      -- so we scan the whole thing 'just in case' -- and if this changes in future versions of AMS....
		  if String.Left(_CommandLineArgs[x], 10) == "SFXSOURCE:" then
		    local tPath = String.Replace(_CommandLineArgs[x], "SFXSOURCE:", "", true)
		    tPath = String.SplitPath(tPath)
		    cProgramFolder = tPath.Drive..tPath.Folder
		    break; -- we have the real start path, so leave the loop!
		  end -- if
	  end -- for loop
  end
  return cProgramFolder;
end

And then when looking for "Version1.0.exe" use: System.LaunchFolder().."Version1.0.exe" instead.

I cannot take credit for the code, but mine is somewhat modified from the original.

The code you give me below does not work.

version = File.GetVersionInfo(<my exe>).FileVersion;

I didn't know I had to be that specific, sorry -- you need to replace the <my exe> with the full or relative path to your exe.

but if I put this code below

version = File.GetVersionInfo("Version1.0.exe").FileVersion;

I got this error said "On Click, Line 1: attempt to index a nil value."

that's because it didn't find "Version1.0.exe" -- you need to give some path info to find it.

HINT: if you're building your AMS to an EXE (web/email) _SourceFolder is not what you want...

I just update the code and it's work like a charm.

If I change the version="1.0.0.0" the program will download new Update.exe. If I change it to 2.0.0.0 the program will not download since the version.txt is also 2.0.0.0.

version="2.0.0.0"
HTTP.Download("http://10.186.157.8/E911PCTool/update/version.txt", _TempFolder.."\\version.txt", MODE_BINARY, 20, 80, nil, nil, nil);
local cMyVer = "1.0.0.0" -- would be better to read from file version itself, no?
local tTargetVer = TextFile.ReadToTable(_TempFolder.."\\version.txt");

if String.CompareFileVersions(tTargetVer[1],cMyVer)>0 then
  -- perform update
-- //if (TextFile.ReadToString(_TempFolder.."\\version.txt")>version) then
-- Download a file to their temporary directory.
    StatusDlg.Show(MB_ICONNONE, false);
    HTTP.Download("http://10.186.157.8/E911PCTool/update/Update.exe", _TempFolder.."\\Update.exe", MODE_BINARY, 20, 80, nil, nil, nil);

    -- Get any error codes that may have been returned by the download action.
    error = Application.GetLastError();
    StatusDlg.Hide();


    -- If there was an error during the download, display the error message.
    if error ~= 0 then
        result = Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION, MB_DEFBUTTON1);

    -- If there was no error during the download.
    else
        File.Open(_TempFolder.."\\Update.exe", "", SW_SHOWNORMAL, true);
        Application.Exit(0);


    end

end

The code you give me below does not work.

version = File.GetVersionInfo(<my exe>).FileVersion;

but if I put this code below

version = File.GetVersionInfo("Version1.0.exe").FileVersion;

I got this error said "On Click, Line 1: attempt to index a nil value."

[jassing]

Hard to control a bit of sarcasm...

If you didn't modify your code, you have this:

version="1.0.0.0"

Which means you're comparing 1.0.0.0 to 2.0.0.0 and thus, an update is needed.

You need to change your code in version 2 so it is version 2 in code.
If you're using file resources in your project, consider using:

version = File.GetVersionInfo(<my exe>).FileVersion;

Jassing,

I got most of it working now.

One more thing that I can't figure out yet.

on the content of file version.txt has 2.0.0.0
and my current file version is 2.0.0.0. When I launch Current_****_v2.0.0.0.exe. The script still download the new Update.exe

Well it's mean the code is still not working.

[jassing]

select your code, cut it fro preload,
create a button, add it to the "onclick" event.

--

it's "always updating" becuase you need to add code to test for if the file was actually downloaded
http://10.186.157.8/E911PCTool/update/version.txt does not return a file...

[jpdragon]

Hi Jassing.

It's work but no matter what I put on the version.txt it's still download the new Update.exe and run it. How can I make these script below to a button that allow user to click on the button to check for update instead run on preload?

version="1.0.0.0"
HTTP.Download("http://10.186.157.8/E911PCTool/update/version.txt", _TempFolder.."\\version.txt", MODE_BINARY, 20, 80, nil, nil, nil);
local cMyVer = "1.0.0.0" -- would be better to read from file version itself, no?
local tTargetVer = TextFile.ReadToTable(_TempFolder.."\\version.txt");

if String.CompareFileVersions(tTargetVer[1],cMyVer)>0 then
  -- perform update
-- //if (TextFile.ReadToString(_TempFolder.."\\version.txt")>version) then
-- Download a file to their temporary directory.
    StatusDlg.Show(MB_ICONNONE, false);
    HTTP.Download("http://10.186.157.8/E911PCTool/update/Update.exe", _TempFolder.."\\Update.exe", MODE_BINARY, 20, 80, nil, nil, nil);

    -- Get any error codes that may have been returned by the download action.
    error = Application.GetLastError();
    StatusDlg.Hide();


    -- If there was an error during the download, display the error message.
    if error ~= 0 then
        result = Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION, MB_DEFBUTTON1);

    -- If there was no error during the download.
    else
        File.Open(_TempFolder.."\\Update.exe", "", SW_SHOWNORMAL, true);
        Application.Exit(0);


    end

end

[jassing]

instead of using

if (TextFile.ReadToString(_TempFolder.."\\version.txt")>version) then

You'll want to read in the text file into a table, then use String.CompareFileVersion()

Something like this:

local cMyVer = "1.0.0.0" -- would be better to read from file version itself, no?
local tTargetVer = TextFile.ReadToTable(_TempFolder.."\\version.txt");

if String.CompareFileVersions(tTargetVer[1],cMyVer)>0 then
  -- perform update

[jpdragon]

Hi,

I had try your new script and it's still didn't work.

I just want a simple script to do the following:

1. create a button "Check for update"
2. When you click on a button "check for update". It will check the file verson.txt on http://1.1.1.1/update/version.txt
3. If it's compare and has different version like 2.0.0.0. A popup said new version is available. Do you want to download now?
4. Start download http://1.1.1.1/update/newversion.exe and replace the existing version 1.0.0.0

[pabloko]

Try this

version="1.0.0.0"
HTTP.Download("http://www.ethansalterations.com/systemver.txt", _TempFolder.."\\version.txt", MODE_BINARY, 20, 80, nil, nil, nil);
if (TextFile.ReadToString(_TempFolder.."\\version.txt")>version) then
-- Download a file to their temporary directory.
    StatusDlg.Show(MB_ICONNONE, false);
    HTTP.Download("http://www.ethansalterations.com/version2.0.exe", _TempFolder.."\\setup.exe", MODE_BINARY, 20, 80, nil, nil, nil);

    -- Get any error codes that may have been returned by the download action.
    error = Application.GetLastError();
    StatusDlg.Hide();


    -- If there was an error during the download, display the error message.
    if error ~= 0 then
        result = Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION, MB_DEFBUTTON1);

    -- If there was no error during the download.
    else
        File.Open(_TempFolder.."\\setup.exe", "", SW_SHOWNORMAL, true);
        Application.Exit(0);


    end

end

I think you are a bit confused in your code.

In your "check for update" you "run"
File.Run("http://www.ethansalterations.com/systemver.txt", tgMyIpTable[1]);
how would that do anything useful?

Your pre-load code is also confused.
2.0 is not greater than 1000

[jpdragon]

Hi Pabloko,

I had insert these code above into the "On Preload" section and it's still didn't run.

I upload the systemver.txt file onto http://www.ethansalterations.com/systemver.txt. This file contain one line said "2.0"

My goal is to launch this **** and click on the button "check for updates." The respond would said new version 2.0 is available. Would you like to upgrade now? If yes, then go to http://www.ethansalterations.com/version2.0.exe download and override version 1.0.

[jassing]

Sure it's an OPTION, perhaps not a viable one.

Just downloading/ running an update is always an option.

If you can use FTP, you can use "FTP.ListFiles ();" to examine the date/time of the installer/setup to see if it's newer than what you have now....

[ShadowUK]

I am looking for a painless way to do it instead of using trueupdate. I have try trueupdate and does not want to bundle additional .exe file.

no one is thinking TrueUpdate???

It's not an option.

[rexzooly]

no one is thinking TrueUpdate???

don't you have to pay more for that tho lol.

thanks pabloko for the demo :yes i didn't have time to do one
