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.

  • SA Bank Account Number Validation

    Hi,

    I am currently working on South African Bank account number validation routines. Unfortunately do I only have access to limited validation rules set out by the banks.

    Are there any developers who have created such a routine,
    or where I can get additional information regarding the different rules per bank?


    Any help will be appreciated.
    Regards
    Walter

    Re: SA Bank Account Number Validation

    I have found a company that will sell a DLL file to incorporate into "ANY" software system to do the account number checking.

    Is it possible to incorporate any DLL file to work with ALpha ??

    Regards
    Walter

        Re: SA Bank Account Number Validation

        Hi,

        I have been trying to call the dll, but no luck:

        The dll to use is called: cdvdll.dll

        The following is one of the dll functions I may use:

        Code:
        (**************** CDV2 ******************
        RETURNS:
         CDV_OK                 = 0;
         CDV_INVALIDBRANCHCODE  = 1;
         CDV_FAIL               = 2;
         CDV_INVALIDACCOUNTTYPE = 3;
        *)
        function CDV2( TSMFilename : pchar;           // SORTED TSM900 data file (MUST BE SORTED!!!)
                       BranchCode  : pchar;           // 6 digit branch code to validate
                       AccountNo   : pchar;           // Account number to validate
                       AccountType : integer          // Account Type to validate (1=current,2=savings,3=transmission,4=bond,6=subscription share)
                     ): integer; export; stdcall;
        The VB Demo script is as follows:

        I have tried to declare this dll, but am getting an error:
        Cannot load / find external library.

        I used this statement to declare:
        Declare CDV2 cdvdll LLLII

        In which folder should the dll file be located?
        I have tried a5v9 and my app_path

        Please assist, as I have no idea on how to get this one going...

          Re: SA Bank Account Number Validation

          You may have better luck working with a HTTP_FETCH() command and using one of the services found here: http://www.quentinsagerconsulting.com/webservices.htm.

          See International Bank Accnt Val about half way down. I have not done this from a desktop application, but it works from the web (generally I mean, I have not used this particular services).

            Re: SA Bank Account Number Validation

            Hello Steve,

            Thanks for the reply.

            The client needs to process hundreds of bank accounts every day and the users do not always have internet access...so I do not think this option is going to work - but thank you for the pointer.

            Do you have any knowledge on calling these DLL 's and how to implement it?
            If I can manage to get Alpha to "SEE" the DLL, would it be a good start for me. At this point am I doing something wrong with the declare statement...so I have nothing to start out with -

            I have been working through previous posts on DLL's yesterday until past midnight, but this one got me good !!

            Have a good day
            Regards
            Walter

              Walter,

              Take a look at this site.

              You can put the dll in the c:\windows\system folder and reference it just by name.

                Hello Marcel,

                Thanks for the reply,

                I have added the cdvdll.dll file to the c:\windows\system folder

                I then declared the following:

                declare cdvdll cdv2 (I am having a problem assigning the argument types)

                This is what the documentation says about the cdv2 function:
                RETURNS:
                CDV_OK = 0;
                CDV_INVALIDBRANCHCODE = 1;
                CDV_FAIL = 2;
                CDV_INVALIDACCOUNTTYPE = 3;
                *)
                function CDV2( TSMFilename : pchar; // SORTED TSM900 data file (MUST BE SORTED!!!)
                BranchCode : pchar; // 6 digit branch code to validate
                AccountNo : pchar; // Account number to validate
                AccountType : integer // Account Type to validate (1=current,2=savings,3=transmission,4=bond,6=subscription share)
                ): integer; export; stdcall;
                What would the pchar equivalent be in xbasic?

                Regards

                  I have added the cdvdll.dll file to the c:\windows\system folder

                  I then declared the following:

                  declare cdvdll cdv2 (I am having a problem assigning the argument types)

                  This is what the documentation says about the cdv2 function:


                  What would the pchar equivalent be in xbasic?

                  Regards
                  Walter
                  Use the C type. It is easyer to look at the VB examples and translate these. I saw you need some necessary structures. Use for these the DECLARESTRUCT or TYPE.... END TYPE

                  Try

                  Code:
                  DECLARE cdvdll CDV2 LCCCL

                    Hello Marcel,

                    Thanks for the help...

                    I was testing with the following, and at least get something back !!

                    declare cdvdll CDV2 CCCLL

                    Dim vN_Result as N
                    vN_Result = CDV2("c:\commercial\leadpol\Accountval\tsm900.srt","012342","144452227",1) '(1=current, 2 =savings, 3=transmission,4=share)
                    'return: 0=ok,1=invalid branch,2=fail,3=invalid acount type
                    It keeps on returning the same integer value (1) , but at least it is a start [email protected]!

                    You mentioned I should use declarestruct .....ok

                    Also, every time I change something in my code, should I restart Alpha ? I think I saw that on your website earlier.

                    Regards
                    Walter

                      Especially when you change something in declarestructs, declare and type..end type constructions. Xbasic is an interpreter and rembers things....

                        This one is working good, thanks
                        DECLARE cdvdll CDV2 LCCCL

                              Hi,

                              Is Alpha storing this DLL file somewhere?

                              Reason for asking:
                              I removed the trial version file from my computer (cdvdll.dll), restarted my computer, then started the Alpha program, it still picks the file up from somewhere when I run the udf calling this dll file.

                              I had the file saved in windows\system folder but removed it from there.

                              Any idea if this file would be saved somewhere by ALpha?

                              Regards
                              Walter
