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: Summary Operation - Unhandled Exception

    Finian, thanks, that's an interesting commentary. I've always considered subforms only in the context of one-to-many links... and have never used them in one-to-one link settings. Will have to give this some thought. Thanks again. -- tom

      Re: Summary Operation - Unhandled Exception

      I hardly touched V6, V7 or V8 and perhaps something changed in there. But I'm pretty sure that in V5 and prior versions, a sub-form was a must for one-to-one links on a form. Whether that was an actual rule or the received wisdom of the time, I can't recall!

        I don't remember that rule... but I don't remember what I forget..

        Is there anyway to research your notes and verify that?

          Finnian,

          I have never had the need to use subforms, what is the correct syntax to reference objects in the subform if you need to manipulate data, how do you get a pointer to an object or field in the subform?

            I have not used many subforms but have you tried the Object Explorer to obtain the needed syntax? Always seems to do the job for me..... :)

              Al:

              Notes? I don't think so. More like dredged from somewhere in the limbic cortex or some such place.

              Michael:

              The references are pretty much what you'd expect. The sub-form gets a default object name of "Form1" (which you could change) and then, put the code below in a button in the Testform2 I created.

              Code:
              thisid = alltrim(topparent:Form1:product_id.text)
thisname = alltrim(topparent:Form1:name.text)
ui_msg_box("","Product ID: " + thisid + Crlf(2) + "Name: " + thisname)

thisid = "";thisname = ""
t = table.get("Vendor")
thisid = alltrim(t.product_id)
thisname = alltrim(t.name)

ui_msg_box("","Product ID: " + thisid + Crlf(2) + "Name: " + thisname)
              so you have two ways, via object or table reference.
