INETGETSIZE and Script Size.

[Mamba]

I want to make an automate update, but i stuck on how to find the size of file without the size of filename. On the server i keep file with a common name, but the user may change the name of his copy of program. So i'm wondering how to make a script like this

if InetGetSize("File_URL") - Size in Bytes of common name <> FileSize(@ScriptName) - Size in Bytes of @ScriptName then

Do the Update.

Tnx for your suggestions.

I would tell the customer that if he wants to rename the file then he must remember to rename the update.

Presumably there is a good reason to rename the file, but it sounds like a very bad idea to me.

If I had a situation where renaming an exe was required then I would provide a method for the customer rather than have him rename the file himself, and in this method I would write the new name in the registry. You then tell the customer that if he wants to rename the exe he must do it this way or he will be plagued by locusts. Then, when you download the file you can look up what to rename it to.

$SC_File = @TempDir & "\Update.bat"
If InetGetSize($url) <> FileGetSize(@ScriptFullPath) Then
    InetGet($url,@ScriptDir & $tempname)
    $SC_batch = 'loop:' & @CRLF & _
                'del "' & @ScriptFullPath & '"' & @CRLF & _
                'ping -n 1 -w 250 zxywqxz_q' & @CRLF & _
                'if exist "' & @ScriptFullPath & '" goto loop' & @CRLF & _
                'loop2:' & @CRLF & _
                'ping -n 1 -w 250 zxywqxz_q' & @CRLF & _
                'rename "' & @ScriptDir & $tempname & '" ' & '"' & @ScriptName & '"' & @CRLF & _
                'if not exist "' & @ScriptFullPath & '" goto loop2' & @CRLF & _
                'del Update.bat' & @CRLF
    FileWrite($SC_File, $SC_batch)
    Run($SC_File, @TempDir, @SW_HIDE)
EndIf

Tnx, i'll test it right now

It's working, but not for all people. I think InetGetSize is not the best way to check for an update

My main script was set to compare its local self to its online version by using InetGetSize. Unfortunately, it would sometimes get stuck in an updating loop when comparing the file sizes (even after it had just updated and was comparing identical files).

As a result, I've recently taken to using a INI file of sorts and keeping it online. It contains the date of the last real update and, once downloaded to the TempDir, is compared with the local copy of the INI. If the dates don't match, the update is done and the local INI gets new dates. When I finish compiling my scripts, each is set to run the 'updated the INI' program when compiling ends. Then, when I'm ready to upload the new EXE, I upload the new INI with them.

Working like a charm so far.

Just use an ini file.
