Reading a file .db

16 posts in this topic

With Autoit 3.3.12.0 a script like the one attached was reading the file "sync_config.db" of google drive, located at %LOCALAPPDATA%\Google\Drive returning into var $sCloudFolder the value "C:\Users\Adams\Google Drive".
Now, with Autoit 3.3.14.1, the same script, reading the same file, return into var a long string of characters.
I made a text version of the file using copy and paste to observe the correct behavior.
I think that the cause is the new method of decoding, but I could not figure out how to solve.

#include-once
    #include <FileConstants.au3>
    #include <Constants.au3>

    ; if the Google Drive configuration file exists, it is read
    If FileExists("sync_config.db") Then
        ; open the Google Drive configuration file in reading
        $Handle_GoogleDrive_R = FileOpen("sync_config.db", $FO_READ)

        If $Handle_GoogleDrive_R = -1 Then ; Check if file opened for reading OK
            MsgBox(0, "Error", "An error occurred when reading the file " & "sync_config.db")
            Exit
        EndIf



        ; reading Google Drive configuration file
        $File_GoogleDrive = FileRead($Handle_GoogleDrive_R)

        ConsoleWrite("$File_GoogleDrive = " & $File_GoogleDrive & @CR)

        ; find folder path initial position
        $Start = 1
        $Find = "local_sync_root_pathvalue\\?\"
        $Result = StringInStr($File_GoogleDrive, $Find, 0, 1, $Start)

        ; find folder path final position
        $Start = $Result + 29
        $Find = ""
        $Result = StringInStr($File_GoogleDrive, $Find, 0, 1, $Start)
        $Len = $Result - $Start

        ; folder for Google Drive Service
        $sCloudFolder = StringMid($File_GoogleDrive, $Start, $Len)

        ConsoleWrite("$sCloudFolder = " & $sCloudFolder & @CR)

        ; close Google Drive configuration file
        FileClose($Handle_GoogleDrive_R)
    EndIf

You probably shouldn't post actual private data like this. Anyway, this file is an SQLite database, which you can open and query with a lot of external tools (try SQLite Expert freeware for example), the SQLite command-line tools (sqlite.exe) or even with your own AutoIt code (SQLite UDF is included in the standard distribution) **.

There is zero chance you can reliably extract anything from this king of file by simply using FileRead nor any other "flat" file function.

Thankyou Celtic88. Ok, your solution working but the approach is more different. And thankyou jchd but you say "There is zero chance" with autoit 3.3.14.1? Because with 3.3.12.0 I was able to read this file using FileRead. The question is: what is changed?

Eureka . I used $FO_UTF16_LE + $FO_ANSI in FileOpen and now the script works. I tried all different "mode" to open the file but had not thought to mix two.

#include-once
    #include <FileConstants.au3>
    #include <Constants.au3>

    ; if the Google Drive configuration file exists, it is read
    If FileExists("sync_config.db") Then
        ; open the Google Drive configuration file in reading
        $Handle_GoogleDrive_R = FileOpen("sync_config.db", $FO_UTF16_LE + $FO_ANSI)

        If $Handle_GoogleDrive_R = -1 Then ; Check if file opened for reading OK
            MsgBox(0, "Error", "An error occurred when reading the file " & "sync_config.db")
            Exit
        EndIf

        ; reading Google Drive configuration file
        $File_GoogleDrive = FileRead($Handle_GoogleDrive_R)

        ConsoleWrite("$File_GoogleDrive = " & $File_GoogleDrive & @CR)

        ; find folder path initial position
        $Start = 1
        $Find = "local_sync_root_pathvalue\\?\"
        $Result = StringInStr($File_GoogleDrive, $Find, 0, 1, $Start)

        ; find folder path final position
        $Start = $Result + 29
        $Find = ""
        $Result = StringInStr($File_GoogleDrive, $Find, 0, 1, $Start)
        $Len = $Result - $Start

        ; folder for Google Drive Service
        $sCloudFolder = StringMid($File_GoogleDrive, $Start, $Len)

        ConsoleWrite("$sCloudFolder = " & $sCloudFolder & @CR)

        ; close Google Drive configuration file

This is utterly ridiculous.

And please don't quote only part of my phrases: I said "There is zero chance you can reliably extract anything from this king of file by simply using FileRead nor any other "flat" file function."

Why do you say that? I read the file and extract the information I needed. And I'm sorry for the partial quote of your intervention but I wanted to take your sentence to ask if you mean that there were no possibilities with version 3.3.14.1.

Why? Because it's true!

You insist on reading an SQLite database as if it was a text file and this is definitely wrong. Use the right tool for that task and stop messing with unreliable ways. It has nothing to do with what AutoIt version you use, even with which language you use to read and "extract" data from the database. If you really need to check by yourself I provide you with a valid SQLite database containing the actual data your file contains (from the SQLite point of view) but from which you won't extract the correct information with your "flat file" read approach.

Of course, I agree that to read a sql file, my approach is not the most appropriate. But for what it takes to me and to read "my" file (and not others) the method worked. Thanks for the advice anyway: if I read another  SQLite database with more complex needs I will use the most appropriate method.

Correction, that should be "my approach is totally wrong". I agree with @jchd on this one.

Adams,

Your "method" will work as long as the sequence of updates in the database leaves the row you're after in the same place. And I bet my keyboard that you don't have control over how "your" DB will evolve since it isn't really yours: it's managed by Google, not you. Google may have to change things a lot over time and you'll be reading the very same free page in the DB while the actual correct data will reside elsewhere. Said otherwise, this is utterly unreliable and you don't have the faintest clue as to when it will silently fall apart.

@jchd,  

Not sure I've seen you this  persistent before.  Please watch your blood pressure and when he doesn't get it by now it surely is a lost case... But it is his case.  ;-)

I found it interesting to see how deep wrong ideas can grow their roots. As you say you and me don't care since we're not the ones who shall hit bricks at full speed.

@jchd, I respect your opinion. I follow many of the topics you post on for your insightful commentary.  I made a mental note of your response on this one.  Thought that its easy to find a quick and dirty fix that will turn into a disaster later.  I agree with advice by @Jos. :)

      What's the best way to receive file from a desktop app?
      app.exe will execute a cmd with "au3file.exe /path/of/the/file.xml" and the au3file.exe will get and delete that. Or else? THE MOST IMPORTANT PART OF THE QUESTION
      And best way to transfer file to a desktop app?
      au3file.exe do a $_POST request and the app.exe MUST HAVE a local HTTP server that can receive $_POST, but it looks heavy 'cause the app must have a server such XAMPP. au3file.exe execute a cmd with "app.exe /path/of/the/file.xml" and the app.exe will now get that file and delete. Or else?

      Good evening everyone
      I'm working on this little project for a week, and, what I'm trying to do could be useful for many users as well...
      I'm trying to do a "Report Generator", which reads the data that have to report from a text file (.txt) formatted with this pattern;
      Data1;Data2;Data3;Data4;Data5;;

      YES, there are 2 semi-colon at the end of the line.

      In detail, Data1 is a date/time stamp with this format: YYYY/MM/DD HH:MM:SS ;

      When the script starts, the user is prompted to choose 2 dates which I'll call as:
      Report_Date_Start; Report_Date_Start. So, the report, should cover all dates between Report_Date_Start AND Report_Date_End.

      And, already at this point, I don't know how to do the query... How can I say to the script:
      SELECT * FROM (.txt) WHERE Data1 BETWEEN Report_Date_Start AND Report_Date_End; ?

      I thought that I could do a _DateDiff, but if the difference between the two dates is months and not days, how can I do the trick?
      Should I make a Switch...Case with the _DateDiff() and see then calculate all the dates between Report_Date_Start AND Report_Date_End... But then, how can I compare the dates in the file with all the dates between Report_Date_Start AND Report_Date_End? I'm going crazy, I know...

      I've already made a "Export Tool", which exports the content of the .txt file in a .db, managed with SQLite... I mean, there I could easily do a query like I did above the thread, but, this "export", for 1080 rows, takes 28 seconds to be done. And, 1080 rows are daily rows that are added every day in the .txt file, so, in a week, the file could be easily 7000+ rows, which means that the "export" would take 3 minutes to be done... And we can go over and over...
      I'll post just for be "complete" what I've done about the export, so, maybe, someone could say how to improve it in terms of efficency...

      About the report in PDF, I'm talking with @taietel in order to know how to create a PDF.
      I hope someone will help me
      Sorry for the "long" list of questions...
      Thank you for everything you've done for me
      I have to say that this is the community of programming language that I've loved most!
      By the way, I'll be back tomorrow in the morning ( ~ 9:15 a.m. Italian time ), so, excuse me if I can't answer before that time.
      Hope you guys have a wonderful day/night.

      Thanks again

      We can get a list of file using the below code.
      Local $aFileList = _FileListToArray(@DesktopDir, "*") Is there any option to use the above one recursively to get sub folders and their contents also.??
      And also, is there any way to serialize the above array locally to some file and load it later when we want in another program on another machine so that we can compare its contents with a folder in different machine, which is not network connected also.?
