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.

    Ok in Change mode but not Enter

    Hi

    I don't understand why this paticular script works ok in Change mode but not Enter mode.

    f = parentform.this
    if F.restrict_enter=.F. .or. F.restrict_change=.f. then
    dis = "Y"
    else
    dis = "V"
    end if
    f:Cond10.refresh()

    I have set my form to mimic A4 in terms of change and enter i.e. not modeless. A field has this script attached to the ONARRIVE event. It will turn the conditional object on and off base on the two variables in Change mode but not enter mode.

    What am I missing. I know..something obvious, but what else is new.

    Thank you

    Robert

    Why not use mode_get() instead of "F.restrict_enter=.F. .or. F.restrict_change=.f."? In enter mode, parentform.mode_get() = ENTER. In change mode, parentform.mode_get() = CHANGE.

      Hi Jerry

      Either way the script fragment does not execute in Enter mode. The conditional object does not display properly. I don't know if the variable is not being set or whether the refresh is not executing or both. As I said the change mode is ok but enter is not.

      Do change and enter execute scripts differently.

        Robert,

        maybe you have a flaw in the internal logic of the script?

        the 'if' statement will fire in all cases until both restrict_change and restrict_enter are true... that's the only the time the 'else' statement will be run

        what are you expecting?

        what are the antecedent property values for restrict_change and restrict_enter, when the form is opened?

        under what circumstances do these properties get changed?

          Robert,
          I did a little experimenting and indeed a conditional object does not work correctly in enter mode. I created a very different code using mode_get() and it worked every time for change mode. In enter mode, the variable value changes and is correct, but the conditional does not work. Do you need a conditional object? If you are using it to show information, you can use a text field and change the text displayed.

          if dis = "Y"
          parentform:text1.text = "Change mode"
          elseif dis = "X"
          parentform:text1.text = "Enter mode"
          else
          parentform:text1.text = ""
          end
          parentform:text1.refresh()

          This seems to work reliably. If you are using the conditional to show or hide other fields, you can use the hide() and show() properties to display the fields you want.

          I normally don't use conditionals since earlier experience with them was frustrating. I have made them work based on the value of a field object, but I find other methods more suited to me.

            Thank you Tom & Jerry...love your cartoons:)

            I use a conditional object because there are three different items to be displayed depending on the variable value. I will have to rethink this.

            At least now know I had it right in terms of coding and its A5 throughing me a curve. Have you noticed that A5 isn't always consistent in handling events under certain conditions. This can be frustrating and time consuming when you think your the problem and its A5.

            Don't get me wrong I thing A5 is a great product.

            Thanks everyone for your responses. I encourage anyone to contribute to this board. You may feel that you are not knowlegable enough and your suggestions obvious...but something you say or suggest could start us thinking in a new direction about our problems.

              Doing the toons was fun, but the residuals aren't much.

              Actually if you only have three fields to hide or show you shouldn't have any problems. You can even overlay the fields and have some default to hidden on startup. (Makes form design interesting) I have a form with many more fields to hide and show that has a script on the OnFetch event. This has lead to "Maximum Stack Depth" errors when fetching quickly. A workaround was found by myself and others and listed in the readme documentation for the 4.03 update.

              Good luck on the redesign. One of the neat things about Alpha is that there are frequently a number of different ways to get the same result. But like any program, it isn't perfect. At least with the help of this forum, a solution can usually be found.

                  RE: Ok in Change mode but not Enter

                  Robert, I've had similar problems and when all else fails I do the following... If the variables are changing correctly, which they appear to be according to Jerry's post of 05-18-2001 08:20. The problem may be that the refresh just isn't working! Maybe it's a memory problem (it doesn't really matter)?

                  To fix this, you might try placing an invisible button on the conditional object (you may have to enlarge the conditional or make a very small button. Place the refresh code in the invisible button; in place of the refresh code at the end of the original script. Place a buttonX.push()where "X" refers to the invisible button object. Work-arounds-are-us.

                    The next to last sentence of my last post may be a little unclear, what I meant to suggest was that you need to place the buttonX.push() code at the end of the original script in place of the original refresh code. Also, you might try a less object specific refresh, if speed isn't a problem. I hope this helps.

                      Tom,
                      Unfortunately, in my test I tried a refresh() and that didn't work. Personally, I just don't care for the way conditionals work. But your test idea is one I use frequently. If I am unsure about how an event or code is working, I will put it on a temporary button. Then I can push it manually or with the push() command and see what is happening. I also use trace.writeln() frequently in scripts to sent information to the trace windows. I have found some interesting surprises about how expressions are evaluating or which event fires first.

                        Hi Tom

                        I need the event to fire when it enters a field.

                        The conditional object diplays a list of different HOTKEYS available to the user depending on the mode they are in and the active field.

                        Thanks for the tip though. It could be handy.
