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.

    Duplicating a "Parent" record complete with "Children"

    Hi everyone,

    I'm a A5 newbie (but very experience DB programmer in other applications)..

    We purchased the products to help us switch some applications to a web based approach.. and so far it's been great!

    However I would appreciate some pointers towards solving what appears to be a simple query (but it's hurting my head!)

    A simplified illustration of the issue:

    We have 2 tables (Projects & Jobs) related to each other bya common "ProjectId".. I would like to place a button on a grid that will (with confirmation) copy an existing "Project" to a new "Project" complete with a duplicated set of "job" transactions. (I will also need to reset some of the attributes - i.e. job status = "Pending" - for all the new jobs as part of the process.)

    Anyone give me some hints/clues/sample code about where to start?

    I guess we need to add a "onClick" event to something on the form and then place some code that actually does the duplication of records - perhaps by using a temporary table?

    If this is pretty difficult to accomplish via the web interface then i would look at a function in the native interface - but web based would be so much better for us.

    Many thanks in advance!

    Here's a basic example. It's for an invoicing system, much like Alpha Sports. And while it's designed to be called from a button on a desktop form, it'll give you a start:


    Code:
    tHdr = table.get("invoice_hdr")
    Current_Record = tHdr.recno()
    HdrCopy = tHdr.record_data_get()
    tHdr.enter_begin()
    	tHdr.record_data_set(HdrCopy)
    tHdr.enter_end(.t.)
    Order_Key = tHdr.invoice_id
    tHdr.fetch_goto(Current_Record)
    
    tDet = table.get("invoice_items")
    tDet.fetch_first()
    tDet2 = table.open("invoice_items", file_rw_shared)
    while .not. tDet.fetch_eof()
    	tDet2.enter_begin()
    		tDet2.record_clone(tDet)
    	tDet2.enter_end(.t.)
    	tDet2.change_begin()
    		tDet2.Invoice_id = var->Order_key
    	tDet2.change_end(.t.)
    	tDet.fetch_next()
    end while

      Thanks Steve!

      Im sure that will help alot - anyone got any advice as to wether that kind of approach will work on a web form (I'm guessing not due to the disconnect nature of them)

      Hope im wrong!

        The basics of this will work on a web form, which is why I provided it. But you'll have to do a bit more upfront to identify the starting table and record.
