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.

  • Refreshing Fields on Calling Form

    Form1 has a button that opens Form2 without closing Form1. Form2 has a button that updates the current record displayed on Form1. Once Form2 closes the values of fields on Form1 need to be refreshed so they display the correct values. The only way I can get this done is to manually press the F5 key to refresh the form data. I could also created a button to do the same. What I would like to do is to put some code on the OnActivate Event of Form1 to refresh these fields. To this point everything I have tried has failed to refresh the fields on Form1.

    If there is a better strategy for this or a suggestion on the proper syntax for refreshing fields via the OnActivate Event I would be very thankful.

    Thank you for your help.

    Hi Rhett,

    Put the instruction to refresh display of Form1 in the Close event button on Form2.
    Here is the script, all built with AS, which does exactly what you asked.
    'Set 'Value' property of 'Editing' in Form 'Memo_Form' .
    parentform:Editing.value = .F.
    'Save record in current form.
    'Close current form or browse window.
    DIM mode as c
    mode = parentform.mode_get()
    'If the form is in Enter or Change mode, first save the changes before closing the form
    if mode = "ENTER" .or. mode = "CHANGE" then
       'Check to see if the record was successfully saved
       if parentform.mode_get()"VIEW" then
          ui_msg_box("Unable to save your changes","Please correct and save, or discard your changes", UI_STOP_SYMBOL)
       end if
    end if
    'Close the form
    'Open a Form or Browse layout, displaying all, or selected records in the layout.
    DIM Shared varP_Jobs_Form2 as P
    DIM layout_name as c 
    layout_name = "Jobs Form"
    DIM tempP as p
    'Get pointer to existing window. In case layout_name is qualified with a dictionary name, extract up to first @. In case formname has spaces, normalize it
    'Test if pointer is valid
    if is_object(tempP) then 
    	'Test if pointer refers to a form or browse
    	if tempP.class() = "form" .or. tempP.class() = "browse" then 
    		'If so, then activate the already open window
    		'Window is not already open, so open it
    		varP_Jobs_Form2 = :Form.view(layout_name)
    	end if
    	varP_Jobs_Form2 = :Form.view(layout_name)
    end if
    'Refresh data in Form 'Jobs Form' at parent level.
    DIM object_name as C
    object_name = ":"+"Jobs Form"
    DIM varP_Object as p
    'Get a pointer to the specified object
    varP_Object = obj(object_name)
    'Check if the specified object exists
    if .not. is_object(varP_Object) then 
    	ui_msg_box("Error","The object '"+object_name+"' does not exist.",ui_stop_symbol)
    	'Can only resynch data in View mode, so save record first to be sure that layout is in View mode.
    end if

      Re: Refreshing Fields on Calling Form

      Another way that I use quite often is to open the second form as a dialog using the OnPush event of a button on the first form. The OnPush script pauses when the second form is opened as a dialog and will resume when the second form is closed. Considering this, the refresh script can be placed on the first form's button OnPush event after the script that opens the second.
