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.

  • How to trap and correct error messages in a dialog control

    I created a simple dialog control based on the template of invoice header and invoice detail, invoice numbers should be unique, i tried entering same invoice number for the sample second data entry, when i click the submit button , for sure an error is detected, how do i prevent this kind of errors and enable the user to determine and correct the error?Thanks!

    Re: How to trap and correct error messages in a dialog control

    As this is an internal error there is nothing the user can do to correct it. What you have done in testing is the right thing to do. Unfortunately as this is a coding problem and you have shown us only the error message as result of the code, there is nothing to advise what you should correct. I suggest you look again at the video that demonstrates what you are trying to do.

      Re: How to trap and correct error messages in a dialog control

      Thank you Keith, i have done and followed it correctly, no code whatsoever and that is what alpha five is RAD little or no code is needed, I guess I have to explore a bit more of the dialog component to figure out how to validate a field so that it wont accept a duplicate invoice and immediately present an error msg to the user for the user to correct.by the way Keith, I posted how to calculate or add a number of days to a date because it was very very very hard to do in the dialog component's calculated expression, there is nothing wrong with numbers to add subtract divide and multiply, but when it comes to date adding it is questionably difficult, e.g. in the dialog component's calculated expression, Date() + 30 will yield an output of 04/21/2012 30.Sorry I have asked again to you here because it was really very very very hard because nobody replied yet till now on the post that i posted , 15 members viewed it but maybe they don't know also, hope you can help us, please be our savior in adding dates.Thank you!
