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.

        Work only in RTL with no problems at all since v8. The only drawback is the Vscroll and Hscroll of browses and embedded browses being LTR in behaviour. The question should be, when does this error occur? Can you describe the procedure which results in the error warning and what is the behaviour after closing dialog?

          Still trying to figure out error.
          I have 6 users on this payroll application.
          Running on IBM System x3400 Server.
          5 Runtime and 1 Development machines.
          Users are spread out over 1/2 mile across this power plant.
          All the runtimes are running fine. I only get this error on my Development machine.

          Any Ideas? memory on development computer?

            Forgive the silly question... Do you have a second Dev machine available to you (since A5 permits two activations)? Have you loaded your development environment on to a second Development PC? And does the problem also appear there? Heading toward, obviously, is the problem PC-dependent?

            And when you say you get this error on your Development machine, is the error produced when running from the Development installation? or the Runtime installation (on your PC)? or both? Thus, if RT runs fine on your machine, may suggest not hardware dependent - rather something unique about Dev.

            Are all machines (and installations, ie: your single machine perhaps loaded with each/both Dev & RT) patched to same level?

            And, although you may find something under MS for Heap stuff, I suspect this specific error is coming from A5 (file: Alpha5.errors), not Windows O/S. That file contains customized error messages, and I believe the developer is permitted to add to the file to implement his/her own unique error messages as well.

            And what is going on with the "t2" operations? I presume this is a reference to your own source code? Have you closely reviewed the sequence of operations leading up to that .enter_end() to ensure that all is proper - and not just simply that it works? Have you closely examined the results of each of the unique operations preceding the .enter_end()?

            I strongly suspect this is not memory related.
