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.

    Ajax limitations with ADO (to SQL server procs)

    Hi, I am evaluating Alpha five and note that it states that "If you use ADO, you will not be able to use Ajax features". Does this mean that Alpha Five is absolutely useless with all its cascading grids etc in anything but its own database ? I was seeking to keep SQL server and all its stored procs and was hoping that a disconnected recordset would be used to populate the Ajax controls. Do I stop and go no further ? Is it possible that the later edition with its use of .Net library won't have this limitation ?

    No--just ADO, not AlphaDAO/ODBC. It's fully functional with all ODBC connections--SQL, Oracle, etc, as well as the native dbf.

      Re: Ajax limitations with ADO (to SQL server procs)

      I should be a bit more specific here. In .Net we bind grids etc to a dataset, the dataset is fed by a stored procedure. When I develop a data driven site the user is often given a url with a guid attached, this session variable is analysed by the stored proc and results returned to a grid. It seems to me the 'Alpha' way would be to get some initialise event, call the proc and pass the results to a buffer table (or get the proc to do that) and bind the Alpha grid to the buffer table. This seems a bit clumsy. The beauty of using stored procs only the data required is ever returned, never is there a potential of filter destruction and internal analysis as cited in this example.

        Frankly, you're over my head here, so I'm sure others out there can respond better. What I do know is that the Alpha grids query the tables when the grid is opened, though they only return data for fields actually used in the grid and/or detail view; I know that some users use stored procedures but if I understand right that's usually on the back end of a user action, not the front end. And little has been published about what the .Net integration will actually be in v11, so I doubt you'll get much info on this...
