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.

Clean the registry

  • Clean the registry

    Occassionally, Alpha will tell you a file is open and/or in use by someone. Maybe when programming, when rebuilding indexes, when opening a file in exclusive mode, or when compacting the adb. And closing and reopening the ADB doesn't help. Nor does rebooting the computer. This is because Alpha often uses the registry for keeping track of open tables and files. And they don't get removed and/or updated properly - especially when there is a crash, or Alpha throws an error or programming code throws an error.

    I am including 3 functions for keeping Alpha clean. The first two were graciously done for me by Stan Mathews, which clean the registry; and the last was done many years ago by Cal Lochlin, which keeps temporary files clean.

    As with any code, use this at your own risk. I am currently using it for one client with a shadowed ADB, and another with T/S.

    function clean_tables as L()
    dim user_data.foo as C
    User_Data.foo = ""
    dim cont as C
    dim rslt_cont as C
    dim cont_ln as C

    Re: Clean the registry

    Thanks for the citation, Martin. We might indicate that the registry functions are currently known to be compatible with A5V8 through A5V10. They will not work with A5V5 due to the registry entries being different.
    There can be only one.

      Re: Clean the registry

      How /when are you calling these functions? In button scripts, menus, toolbars or from the IW? And does it matter!

        Re: Clean the registry

        Sorry about that - should have mentioned
        there are 2 ways to do it

        1. manually, from the controlpanel
        2. from a button, run a script that will first close all forms, including the form the script is run from - then call the functions - then reopen the form(checking to be sure it is not already open.)

                Re: Clean the registry

                Martin,

                I have been having many problems with Alpha and I thought these functions could not hurt. I was curious what they are doing.(My xbasic skills are limited) and how to implement this. Currently I created 3 separate functions and put them on buttons. There is an "on error" which is before the function definition so I was not sure where to place this. I would assume if running this in the autoexec, you would create 3 separate functions on the control panel and then just run the functions, correct? Thanks.

                    working as advertised
                    the registry will only very occassionally be an issue, but when it is it is a bear to trace - the first two functions take care of the Alpha registry

                        Martin,

                        I'm sure I'm missing something. I've tried to run your script from within my database and it doesn't appear to clear out the temp files.

                        Do I need to add the path to the temp files?

                        Thanks,

                            I work with Dave, so I can answer that...

                            It's putting them in the same directory as the .adb and most of the associated tables, which is \\fs1\q:\alf55\

                            We can (and do) delete them manually, but thought it would be handy to have it done this way.

                            A few of our Shadowed users push a button at night to kick off a bunch of linked Action Scripts, and we'd like to add this script to be run first.

                            Thanks!

                              Works fine here on the location you mentioned.

                              I do note that you called it a script and you tried to run it. Actually it is a function and you have to execute/call it like.

                              cleanit()

                              If you modify the function slightly

                              Code:
                              function cleanit as L()
                              cleanit = .F.
                              DIM path[10] as c
                              path[1] = a5.get_path() + chr(92)
                              path[2] = a5.get_private_path() + chr(92)
                              pcount = 2
                              IF a5.get_private_path() <> a5.get_exe_path()
                              path[3] = a5.get_exe_path() + chr(92)
                              pcount = 3
                              END IF
                              fcount = 0
                              FOR x = 1 to pcount
