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.

    Re: Problem with a set

    Mike, go for Al's offer. It will save your sanity.
    Question, and none of my business, but I have been there, why are you replicating in Alpha and not using the data in AM and building on Alpha's powerful features?

      Re: Problem with a set

      I apologize for starting a discussion, then seemingly abandoning it. Overtaken by events as they say. I was preparing to take Ted's advice, and take you up on your offer of help. To do so, I created versions of my three tables with no rows and tried to create the set again to see if the same problem occurred without data. It did, but before sending it off I fiddled around some more. The problem is indeed due to the space in the name of the "line item" table. If I remove the space, no problem. The strange thing is that the "buyer data" table name has a space, but gave no error. When I looked in the set build genie it showed that when buyer data was added to the set it had an alias of "buyer_data". I don't recall creating the alias and I added both buyer data and line item to the db in the same way. The problem is introduced because a number of the dbf file names in the Approach version have spaces and I tried to use them as is. As I've just mentioned, some seem to be handled OK, others not. Clearly the fix is to remove the spaces, which I will do. However, it does seem that A5 is handling file names/table names with spaces in a confused way. It would make sense for it to object to invalid names when it is parsing the names of things being incorporated into an application.

      Anyway, it's solved, and I appreciate everyone's feedback.

        Re: Problem with a set

        Regarding item 2 below - If my memo field is just called memo, and I try to display it's content in a form, "Approach bitmap" appears in the form. If I change the data type to bitmap, nothing appears in the form. I haven't had time investigate fully yet, but my suspicion is that when A5 seems a memo field, it's displaying what type of memo field it is (if it can). If it's a bitmap field, A5 tries to display the bitmap, but if it can't find the content it (sensibly) displays nothing. I'm wondering, when I add the .dbf and corresponding .dbt files to the db, does A5 automatically turn the dbt file into and fpt file, or do I need to do something explicit to make the conversion. I'll be looking for the answer to that question next, but if anyone has the information handy or can point me the right way, I'll be grateful.

        Welcome to Alpha. Approach is nice system and easy to use. Too bad it is deprecated.

        1. In the set definition you have the linking established between parent and child. So you either enter a new parent, or find an existing parent and the child is attached to the parent using the set definition.

        Are you building a form based on the set with the parent record and the child as a browse? Look at the AlphaSports sample as a template to design from.

        2. In the table definition is the image field defined as a memo field or a bitmap field? Bitmap will work with a memo field that is holding an jpg or png too.

        Not sure if this is an option, but some choose to store images outside of the dbf and refer to the location of the image file. That helps to keep the size of the dbf smaller. But that may not be an issue for you...

        Hope that helps.


          Re: Problem with a set

          Word of caution, do not create a memo file in a serious table. Create a second table for each memo field with a connection field and the memo. There is much written here about that.

              Not sure that a dbt will transfer to fpt.
              You would be better with all the data, to export it to Excel or CSV and reimport. That way, when you import, you will trap any errors.

                Michael, I've noticed this problem (mishandling object names with blank spaces) more often when the object name that has blank spaces includes the name of a built in function. In this case, Alpha has a LINE() function. See what I mean? However, I don't claim that this is always the case...

                  Re: Problem with a set


                  That solves the mystery! I changed the name of "line item.dbf" to "linx item.dbf" and everything worked. I think A5 should handle this better (i.e., disallow names it violate its rules), but the requirement that spaces be avoided is not unreasonable in itself. I inherited these names and have to maintain them as much as possible. I wish A5 would maintain the case of file names, table names. I'd use LineItem.dbf and avoid spaces and underlines both.

                  Thanks again,
