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.

    mdi xdialog with html form bug?

    I am in the process of creating an MDI dialog with an HTML form on it, there seems to be a problem whereby as soon as I enable the MDI part the data disappears as in this video (this is a reverse. MDI is enabled to start with, then I CTRL-X the relevant parts for the MDI to work so the dialog is just a stretchable modeless dialog and the data appears) http://screencast.com/t/vabeMC73pR
    anyone any ideas?

    i would start with a trivial simple test case and see if that works as expected. then start incrementally adding complexity to see what broke it.

    if the trivial test case does not work, then send it to us.

      I thought it was a trivial simple test case, I just made an xdialog with an html form on it which had label and input tags on it which worked then added the mdi section and it did not work! take out the mdi section again and it works.

      I will sort out a copy and send it to you along with another bug I found over night which is totally unrelated.

        It is not a bug.
        You are dimming a whole bunch of variables up front that you then bind to the html controls on your form. You have dimmed these as shared variables.
        I can't see any reason why they would need to be shared variables.
        If you dim them as local variables it will work.

        The reason that it does not work if you dim them as shared variables is that the shared variables are dimmed before the mdi xdialog is instantiated. The 'shared' variables therefore belong to the calling session. However, the MDI window is created in its own session. So therefore, the MDI window does not see your shared variables. However, the MDI window ***does** see the local variables in the script. Which is why it works if all of the variables are dimmed as local, not shared, variables.

        The reason that it ***does*** work if you remove the {MDI} command is that the Xdialog is then created in the same session as the calling session, and so the shared variables are visible.

        Alternatively, you could have wrapped all of the code that you are executing up front to initialize the variables into a function (say initfunction()) and then you could have called this function from the 'init' event of your Xdialog. You could then either create these as shared variables, or local variables.

          Thanks Selwyn, now on to design some great HTML MDI dialogs.

          If only I had taken the time to read the help files first!
