need help getting file version

[Wyleyrabbit]

Hi Everyone!

I'm new here, and new to AutoIt. What an amazingly simple yet useful language AutoIt is. Kudos to the developers.

I'm writing a script to check the currently installed version of various programs. For my test case, I'm checking the current version of Firefox to see if it needs to be upgraded.

Unfortunately, FileGetVersion seems to return some unexpected results. For example, version "1.5" is the current version, but FileGetVersion returns it as "1.8.20051.11116"

$fileversion = FileGetVersion("C:\Program Files\Mozilla Firefox\firefox.exe")

By right-clicking the exe file and hitting "properties" then the "version" tab at the top, I see what's going on. The "File Version" may indeed is "1.8.20051.11116" so I guess it's the "Product Version" I'm really after, since that says "1.5".

After doing some googling, I figured out that one can probably do a DLL call to get the information I'm after. Unfortunately, I don't come from a windows programming background (most of my coding has been in Perl on *nix) and I therefore have zero experience talking to DLLs.

I managed to put the following code to work, which happily returns a "0". My suspicion is that the "0" simply means that the DLL call was successful, but I'm not sure of that either.

$file = @ProgramFilesDir & "\Mozilla Firefox\firefox.exe"

$dll = DllOpen("version.dll")

$result = DllCall($dll,"str","ProductVersion","str",$file)

DllClose($dll)

MsgBox(0,"version",$result)

Thanks for any help or suggestions.

Cheers.

umm i think there is a registry key saying your current firefox version... gimme a sec to find it

here we are

$ver = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla.org\Mozilla","CurrentVersion")

--did this help?

Hey. Thanks, but not quite.

That returns "1.8b4" on my machine (which has Firefox version 1.5).

Besides that, I'd like to be able to read the "Product Version" of other programs as well. Any further ideas?

Try this:

$ver = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox","CurrentVersion")
$status = 1
$x = 1
While $status <> 0 or $status2 <> 0
    $trimed = StringLeft($ver,$x)
    $status = StringIsFloat ( $trimed)
    $status2 = StringIsInt ( $trimed)
    $x = $x + 1
wend
msgbox(0,"The version number is:","The version number of firefox is: " & $trimed)

It could probably be done more efficiently than that, i just wrote that script up real fast. It seems to work though. I hope it helps.

Ok, that works brilliantly! Thanks.

Now the trick is going to be trying to figure out which programs I can just use the built-in "FileGetVersion()" command and which ones we can't.

So, is it even possible to do it the way I was initially trying to do it? By making a call to the version.dll file? Could be a very useful thing for me (and others) to know how to do. Anyone? Anyone? Bueller?
