Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Could not open OLE Object 'adodb.connection'

    Hi Gang,

    seems I have strayed into the unknown/forgotten land again!!

    I've returned to something I was using 18 months ago, but it does not work anymore so I am at a loss as to where to start:

    Using SQLite3 ODBC I want to get records from an SQLite3 database and import them into an A5V8 table.

    dim Conn as ole::adodb.connection
    dim ConnString as c = "Provider=MSDASQL.1;Persist Security Info=False;Extended Properties=\"Driver={SQLite3 ODBC Driver};Database=c:\Program Files\Kinetic\BaseStation\basestation.sqb;StepAPI=0;SyncPragma=NORMAL;NoTXN=0;Timeout=2000;LongNames=0;NoCreat=0\""
    conn.open(ConnString)
    tbl = table.open("Get_SBS_Logging",FILE_RW_EXCLUSIVE)
    tbl.zap(.t.)
    tbl.close()
    tbl = table.open("Get_SBS_Logging")
    dim sqltext as c
    sqltext = "SELECT Registration, FirstCreated FROM Aircraft WHERE Interested = -1 AND UserString1 is null"
    delete rs
    rs = conn.Execute(sqlText)
    while .not. rs.eof()
    tbl.enter_begin(.t.)
    tbl.Reg = rs.fields.item("Registration").value
    tbl.FirstCreated = rs.fields.Item("FirstCreated").value
    tbl.enter_end(.t.)
    statusbar.Set_Text("Reg "+ut(tbl.Reg)+" Retrieved")
    rs.MoveNext()
    end while
    rs.close()
    conn.close()
    tbl.close()
    This used to run quite happily before, but I now get the message:


    Could not open OLE object 'adodb.connection'

    the only difference I can see is that I ran it on A5V7 before and now I am using A5V8. Is there a difference in the way the OLE::adodb works under V8?


    I also tried
    ?a5_connectionstring()
    in the Interactive window and got the same error message

    Hi Graham,

    I can't help you with the adodb problem. Probably it will be one of those very small misspelled characters in the connection string. ;)

    Maybe the next link can help you.

    There is a kind of LiteX Automation � automation wrapper around SQLite3 library. This wrapper is useful if you want to use SQLite3 databases in Visual Basic or any scripting languages such as JScript,VBScript and AutoIt3.

      Could not open OLE Object 'adodb.connection'

      I am getting a similar error after loading A5V7 and my application onto a new laptop.

      "OLE Automation Error. Source is ADODB.Connection. Provider cannot be found. It may not be properly installed."

      The error occurs on the dim statement before any attempts to use the connection object.

      dim conn as ole::adodb.connection

      I am running Windows XP with MDAC 2.8 SP1 ON WINDOWS XPSP3 and it appears to be a viable version after downloading and running the MDAC CompChecker.

      I also tried loading ODBC .NET, and this did not help either.

        Re: Could not open OLE Object 'adodb.connection'

        I have come across the same problem. However the difference for me has been between using A5v8 Pro and A5v8 Enterprise. My script which is similar in design to the one above works only in the Enterprise version. I have two machines that are identical in setup at my office. One has Enterprise and one has Pro. Only the Enterprise edition executes the script without error.

        Why is that? I hope that someone from Alpha can look into this or at least give an explanation. This is a rather frustrating issue. Are there any work-arounds that anyone has found for this?

        Graham, what did you find out?

        I know that this is a very old thread, but we have been slow to upgrade our apps and have just done so in the last year and just recently come across this problem.

        Any ideas or info would be greatly appreciated! Thanks!

          I thought that the Pro edition is for working with dbfs and the Enterprise edition is for working with a more expanded list of data sources.

          You haven't stated what your script does or what data source it is connecting to. I'm not surprised that a script might only work in Enterprise - depending on the features that the script is using.

            If you are attempting to use ADO / AlphaDAO then Alpha Enterprise must be used. This has been stated on the Alpha website and on the messageboard.
