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.

    Integrating a SQL procedure with Alpha5 V11

    I have a procedure in SQL and want to integrate this with Alpha5, how can I do that?

    exec dbo.CheckOutAddresses '<ApplianceName>',<num ips to reserve>,'<LabLocation>','BMC','<Your Alias>'

    So the ApplianceName. Num IPS to reserve, LabLocation and Your Alias are variables.

    How can I use these.


    Re: Integrating a SQL procedure with Alpha5 V11

    First thing you need to do is create an xbasic function using the create function prototype. After that you will need to do something like this.
    function YOURFUCTIONNAME as c (e as p)

    dim flagResult as l
    flagResult ="::Name::YOURCONNECTIONSTRING")
    if flagResult = .f. then
    ui_msg_box("Error","Could not connect to database. Error reported was: " + crlf() + cn.CallResult.text)
    end if

    'If you were firing this from a dialog you could use the e.dataSubmitted.yourcontrol name to pass in your parameters

    'Specify if you are using Portable SQL syntax, or not
    cn.PortableSQLEnabled = .f.
    dim sqlStatement as c
    sqlStatement = "exec dbo.CheckOutAddresses '"+ApplianceName(characters need double quotes as well as single numeric just needs double quotes as well as the plus signs+"',<num ips to reserve>,'<LabLocation>','BMC','<Your Alias>'"

    'Execute the Query
    flagResult = cn.Execute(sqlStatement)
    if flagResult = .f. then

    end if

    'Now, close the connection

    end function
    Now if you need to pass in variables using java script you need to pass them in to the ajax call back this is a little more complicated and I know how to do it but it would be much easier to show you in your application.


      Re: Integrating a SQL procedure with Alpha5 V11

      Thanks for that information, let me show you what I want it to do.

      I have an import from excel button, and before I run the excel import I need to count the total IP's that need to be reserved. Then I need to see if IP's are available in the range, and if not an error should come up stating that there are not enough IP's


        Re: Integrating a SQL procedure with Alpha5 V11

        just to add to the above, use arguments! (avoid sql injection, is easier to read, does not require string concatenation)

        dim args as SQL::Arguments
        sql="exec dbo.CheckOutAddresses :address"
        if conn.execute(sql,args) then
        'do something
         'handle error
        end if

          Re: Integrating a SQL procedure with Alpha5 V11

          'read import

          'gather ips into list

          'run ip list through function (1 by 1? or all at once? - depends how your function is coded)

          'if error then error out with not enough ips
