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.

  • User Message

    I have a set made up of "salesman" (parent) and "sales" (child). the form asks for a date range (works fine) and sorts the child records according to the range selected. There is a calc field "total sales" on the form. I want to display a user message "processing, please wait", when the user goes to the next record, or when he/she selects "find by key". After the "total sales" field has re-calculated, I want the message to go away. Ideas?

    RE: User Message

    John,

    Use a text box control instead of ui_msg_box() and have your script hide it when the form loads, show it when you want to, and then hide it again later on.

    If you have trouble synchronizing the sequence you may find that it will work better if you use three user defined functions:

    1) the first would show the text box
    2) the second would do the calc or summary computation
    3) the third would hide the text box

    By putting these routines in separate functions each will run to completion before the next begins.

      RE: User Message

      Tom,
      I am testing your suggestion. Very clever. I created 3 functions (see below) that set a message text, sleep for 1 second, and then clear the message text. The 3 functions are played in the form's On_Fetch event as:

      func_showmsg("Fetching...")
      func_sleep(1)
      func_hidemsg("")

      It works great! I do have 1 question. I had to hard code the form name (f_payroll) in the func_showmsg and func_hidemsg functions. I have tried a dozen different ways to use a global pointer which would make the functions generic. Any ideas on how I can do that?

      Thanks for your help.

      function func_showmsg as L(message as c)
      on error goto failure
      dim global g_msg as c
      f_payroll:g_msg.value = message
      f_payroll:g_msg.refresh()
      func_showmsg = .t.
      on error goto 0
      failure:
      func_showmsg = .f.
      on error goto 0
      exit function
      end function

      function func_sleep as L(seconds as N)
      on error goto failure
      sleep(seconds)
      func_sleep = .t.
      on error goto 0
      failure:
      func_sleep = .f.
      on error goto 0
      exit function
      end function

      function func_hidemsg as L(message as c)
      on error goto failure
      dim global g_msg as c
      f_payroll:g_msg.value = message
      f_payroll:g_msg.refresh()
      func_showmsg = .t.
      on error goto 0
      failure:
      func_showmsg = .f.
      on error goto 0
      exit function
      end function

        Gary,

        If I understand your question properly you would like to be able to use the same function on multiple forms and messages and pass the reference to the form from function to function.

        I solved a somewhat similar problem by putting the name of the form in a variable and passing that around creating pointers locally as necessary which would probably not be necessary in your case as you could write:

        eval(vFormname+":g_msg.value") = message

            Bill and Jim,
            You guys are the best. I tried both solutions and both worked like a charm (6 ways to skin a cat). THANKS. The next step is to perform some calculations on the form while displaying the "Fetching" message. Functions are unchartered territory for me, but the more I use them, the more I understand and like them.
