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.

  • OnTabChange not firing

    Has anyone else seen this? An experiment showed that the OnTabChange doesn't fire when the tab is changed to the first tab. It fired whenever I changed to any other tab, but when tab 1 was reselected, it did not fire.

    RE: OnTabChange not firing

    Jerry,

    Ihave a form containing a tabbed subform with 5 tabs. I have just added a numeric variable tab_test to the form and placed this script on the ontabchange event.

    tab_test=Tabbed1.Tab_Get()
    sys_send_keys("{F5}")

    It reads all tabs. Are you sure that you have selected the correct event. I am always making this mistake.

      Michael,

      I have used this event previously without problem, which is way I was puzzled with what I saw. I just went back into the form and retested to check if the event fires. It does under almost all situations except one. If I change the color properties of the tabs when the focus is on tab 1, everything fires. But if the active tab is any other tab, like 2 or 3 and I change the tab color properties (selected or unselected color) of any tab, the OnTabChange event doesn't fire if tab1 is the next tab selected. If any other tab is selected right after the color change, then it does fire.

      As a test, this is what I did. I used a button script to prompt the user for a color value and then added the line to the end of the button script

      parentform:Tabbed1.tabs.sheet[2].unselectedcolor = color

      to change the unselected color of tab2. On the OnTabChange event, I had the following

      number = parentform:tabbed1.tab_get()
      trace.writeln("OnTabChange for tab "+alltrim(str(number)))

      I opened the form and the trace window. If I pushed the button with the focus an any tab but 1 and then selected tab1, no message in the trace window. Under any other scenario, the message appears.
