ADO.au3 UDF - BETA - Support Topic

Recommended Posts

I have another question about with this UDF. My goal is to make a application that will handle the content of a SQL db. I know for sure that more than 1 person would edit the content in some way. Do you read the content to an array with this UDF? What happens if 2 people for an exampel edit the content at the same time? The content will then be read in an array on each copy of the runned application.

you can do what you need but as far as I know you must to block the changes, by adding new column in which you will set the blocking state, and check it by each other user.

Maybe there are other way , but I'm not so burly brain to know all the tricks ;)

I think @Valnurat is asking about that situation:
user1: is reading content and start processing
user2: is reading the same content and start processing in another way, so he finish faster
user1: is finishing his processing

I think user @Valnurat is asking what to do if we want to stop User2 from reading content, until user1 is finish his processing.

I do not think in this case Transactional processing is changing antyhing, but as I said I do not know  all the tricks.

What you describe isn't possible in bare SQL. Transactions (either implicit or explicit) isolate users. To synchronize processes as in your example you need some IPC between applications (or threads or whatever else).

To answer post#1 you can block a second writer by using an IMMEDIATE or EXCLUSIVE transaction issued by the first writer. All other users will see the DB state before the transaction began. Only when first writer issues COMMIT all users will see the DB state after the transaction has taken place.

There is no such thing as two users updating the DB simultaneously, technically speaking. Some client/server engines use giant caches and sophisticated algorithms to make you believe two writes can occur simultaneously but at the DB level, that is plain impossible. Else the ACID properties of the DB would be jeopardized.

In your last example, if user1 intends to read-modify-write stuff, he needs to do:

-- DB is in state A for all users
[user1] BEGIN IMMEDIATE;
[user1] SELECT stuff
[user1] mix up stuff inside application
[user1] UPDATE old stuff
-- and/or
[user1] INSERT new stuff
[user1] COMMIT;
-- DB is now in state B for all users

Right after BEGIN IMMEDIATE is fully processed and until COMMIT isn't, all other users can only see the state A. At the moment when COMMIT is fully processed, the state of the DB is B for all users.

Engines differ in how the locking is implemented and how wide it is. For instance SQLite locks the entire DB, while other engines (mostly client/server types) can only lock a table, or even affected rows or even affected columns of affected rows.

The question is not if this UDF does this but: how this UDF does this ?
The answer is you should read all this documentation/articles which I posted few minutes ago, and find out how to use it with this UDF.

I can not answer precisely, as I do not have the oportunity to use this feature which you are asking, and I currently have a small amount of spare time (Unfortunately, still, but things are improving).

I worked on a few new UDF (TeamViewer, Chilkat, and some other) to my work, but I still have a lot of confusion and I need to do more to work than to the community (I hope to back and finish some projects and then get on with few new).

But you can always ask and I or someone else will try to answer as much as possible.

Yes, it is true.

Here is my goal. I have a small tool that should update the SQL DB automatic. That tool will run i non working hours.

What my tool will do, is that it should look for 3 columns. If 1 of them has changed then it should update the record. Do I read all content of the SQL DB to an array or do I do a "select...something from TableName" with some criteria?

I think the second option should be much better in this case.

Every time our users login to our system, a file is generated. In that file, username, model of the computer and the servicetag is added. The name of the file is the_name_of_the_computer.txt. If the username has change or the servicetag is empty in the SQL DB, I need to update the SQL DB record for that computer. How can I pick the records I need with my criteria and should it still be the second option? It could be 300 + files every day. I don't know if I aproach this task the correct way.

An update statement doesn't return any result, so the assignment to $oResultset is a no-op and can be removed.
Note that if no row with ComputerName = 'DKSOLT1453' exists, this isn't an SQL error as (1) the statement is valid and (2) it didn't have anything to do (but that is perfectly legal).

ADO would normally raise an error if something  turns bad, so use an object (COM) error function to trap those cases.

Ask the UDF author and/or refer to associated documentation. BTW the identifiers you mention look like event names. Traditionnally, transaction statements are processed with SQL Execute function, i.e. statements not intended to return a resultset.

      Good morning, I am trying to figure out if it is possible to check if these invoice lines exist or not. 
      Here are the table and column name: INVOICELINE.INVOICELINENUM (a required field if created)
      Here is a picture of what I am talking about. (Do not worry about security. the picture is from a demo test site so all information is fake)
       
      is there any way to check if these fields exist or not? (they do not exist unless the user clicks on "New Row")
      Example: line 11 does not exist right now. How would I go about to see if it did or not? 
      This is what I have so far:
      SELECT DISTINCT iv.invoicenum, iv.description FROM invoice AS iv JOIN invoiceline AS ivl ON iv.invoicenum = ivl.invoicenum AND iv.siteid = ivl.siteid /* = 'nothing' and yet somehow not null? */ WHERE iv.invoicenum NOT IN (SELECT invoicelinenum FROM invoiceline WHERE invoicelinenum IS NOT NULL) I get 0 results where I should get more than 0.

      Only early days at this point, but I have been pondering such a program for a while.
      As good as calibre is (thank you Kovid Goyal), which is a great and wonderful ebook suite of tools and a fair database, it does have its limitations. One of which, is how it deals with multiple libraries, another is the views you get. CalibBrowser will seek to address those.
      What CalibBrowser is not going to be, is an editor for existing calibre libraries. That will be left up to calibre, which is very much needed still, and covers many aspects I will never look at. Unlike calibre, which is quite a complex program, CalibBrowser also seeks to be simple. It is mainly a viewer, at this point, but will later be able to create its own libraries. However, it does not and will not export them to calibre, especially as calibre employs a far different method and structure to what CalibBrowser will employ.
      When CalibBrowser starts, it looks for calibre executables and the main Calibre Library. Whatever isn't found, you get prompted for with a browse option.
      A calibre library, is a set of ebook folders (Author\Ebooks) and a database file, always named metadata.db, and which causes an issue when it comes to multiple libraries, but makes life a bit easier when reconstructing any corrupted libraries. However, there are better ways to deal with that, as my program will show.
      The metadata.db file is an SQL database, so I am having a learning curve right now, as I have only ever dealt with an SQL database previously, codewise, when I created my INItoSQL program some time last year, as an exercise to prove a point.
      At the moment, things are pretty basic, and not everything works 100%. Here is a screenshot, to give an idea of it, but keep in mind, I intend to expand the current GUI for other stuff I will be adding.

      Older Screenshots
      Gawd, I just noticed the '3|7' in the Book Input field (original screenshot). I was using that during troubleshooting for the multiple images scrolling and forgot to disable it ... not that it impacts anything. When it comes to maths, I struggle a bit, especially when tired. Right scrolling was easy, with a continuous loop, was easy to implement. Left scrolling was significantly harder for my poor brain ... until I realized I needed to see them as Min and Max.
      As you can see the program is usable, and all the buttons, aside from the Program Information one, work. You can even load different calibre libraries, and even reload after making changes to one with calibre. The calibre program does not need to be running, even to view an ebook in the Calibre Reader. The combo selector for a library and the ADD button are only temporarily placed where they are, until I expand the GUI.
      My intention at this point, is to add another five thumbnail images, directly below existing. Currently they aren't clickable, but I may add that.
      Here is another screenshot, of what you see when you click the larger Cover image.

      If you want to have a play with the program as is, then you will need to also get the 'sqlite3.dll' file from some online source. When CalibBrowser starts successfully with the selected calibre library, it copies its metadata.db file to a sub-folder of the program called 'Backups'. It also creates a sub-folder in that, based on the library name, to house it. That copied file, is the one the program uses, though it does not even edit that, and file modification is checked every time the program starts with a particular library, or when you Reload or select a library. If the original source file has been modified, then the program copy is overwritten. The Reload Database button does nothing, if there is no change detected, and reports such.
      Place the required 'sqlite3.dll' file in the CalibBrowser root folder. Download includes source files (sqlite3.dll excepted).
      Also required of course, is an install of calibre, plus some ebooks in a created library - Calibre Library is the default when you first add ebooks to calibre. The Mobile Read Forums, is a great source for all things ebook, and calibre can be found there in the E-Book Software section.

      My apologies for the program being created in AutoIt v3.3.0.0. It is the first one I have done in a while, with an older AutoIt version. Basically my Win 7 Netbook, which has a current version of AutoIt, was busy and is always busy doing something, and not suitable for doing big projects for several reasons. My older but more powerful Win XP Laptop, has a better programming environment, better computer chair (most important for my knees etc), better external monitor (wider and newish), full size external keyboard & mouse, and a great suite of setup tools to assist me. I run several older versions of AutoIt already on my Laptop, but haven't yet determined what I need to adjust to add a current version of AutoIt to the mix. This also applies to my hugely beneficial Toolbar For Any program (one of those tools), which I constantly use with SciTE. At some point, when finished, I may update the program to the current AutoIt version ... especially as I believe I am now proficient enough to do so, having become quite familiar with it in the last year or so, making many programs with it.
      Enjoy!

      Hello guys! 

      I am having some difficulty in achieving a very simple task here. I have gone through the forums and tried some examples and UDFs but I can't seem to work it out. I would really appreciate if someone could help me out. 

      Problem:

      Currently, I am logging the required feedback from the script into a log file in a simple way ... get the info in the var >> write it in the file 

      But now I am in need to perform some analysis and need some of the values to go into an MSSQL table  in the attached format
      Also, I need to be able to use Integrated Security" or "Trusted_Connection set as true or use the logged in windows credentials to connect to the server/database




      any help will be much appreciated!!!  

      Thanks!

      I have created this function for a database, but I can not make it work. I always have two error messages: "not an error" ... and the file created, in the script directory, does not contain anything.
      Global $sDBName = "Hen.db" Func DatabaseTable() Local $sConnDB _SQLite_Startup() If @error Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", "SQLite.dll Can't be Loaded!") Exit -1 EndIf $sConnDB = _SQLite_Open($sDBName) If @error Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", "Can't Load Database!") Exit -1 EndIf If Not _SQLite_Exec($sDBName, 'CREATE TABLE Animal ("Name", "Age");') = $SQLITE_OK Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", _SQLite_ErrMsg()) If Not _SQLite_Exec($sDBName, 'INSERT INTO Animale VALUES ("Charlie","5");') = $SQLITE_OK Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", _SQLite_ErrMsg()) _SQLite_Close($sConnDB) _SQLite_Shutdown() EndFunc
