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.

  • Table fetch_first


    I have an weird case, my script does not read it from the first record when I selected the last record of the Browse or it start to read from slected browse line to last record.

    Does your Alpha five goes to 1st record of table when you selected the last record of the Browse?

    dim tEstHd as p
    tEstHd = table.get("estimate")
    dim tEstInd as p
    dim vEsthdId as c
    dim vProduct as c
    dim vLineQty as n
    tEstInd= table.get("estindirect")
    while .not. tEstInd.fetch_eof()
       vProduct = tEstInd.product_id
       vLineQty = tEstInd.quantity
       if vLineQty >0.01 then
          ui_msg_box("Result","The Current line is "+vProduct ,UI_INFORMATION_SYMBOL)  
          ui_msg_box("","No Current Qty "+vProduct,UI_STOP_SYMBOL) 
       end if
    end while
    I attached the zip files, open the Estimate then select last Record of browse then click "Product" button.

    John, I haven't had a chance to check your zip file, but this may be a case where you should be using <tbl>.get_cursor(). Check the help file topic

    tbl.get_cursor method

      I could not find the <tbl>.get_cursor() from my A5 Help. Did you mean <???>.get_cursor()?

        Re: Table fetch_first

        Hi John,
        I tried this in your xEst_Product script and got the message for No current quantity when line 4 was selected in the browse.

        dim shared recno as n
        recno = topparent:browse1.current_record()
        tEstInd= table.get("estindirect")


        Thanks for the files - now we can play, er, I mean help!

          John, I'm using the wiki help system. (Alphapedia). using the "search wiki page" text box I entered what I told you...


          If you're using the CHM help system I think you'll find it in the release notes under the catgory what's new... but I can't remember for which version.

          -- tom

            Re: Table fetch_first

            This looks like the equivalent of using a browse method, without having to find the record number first. Which would be good to use for changing just that one record. Can we assume the table pointer is following the same order of the browse even if they are not in record number order? The example uses a fetch_next(), so if the user sorts the records in the order he wants, he can then pick which records to change from the record he has placed the cursor?

            Looks like a great function for this. My idea would be more for making changes to all the records in the browse, though this function could do the same.

              Tom and Robin,

              Thank you.

              I thought I wrote bad scripts and my A5v9 was installed wrong.
