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.

  • Grid based on MySQL stored procedure example

    Hi,

    Does anyone have an example of a grid component based on a MySQL stored procedure, with a parameter?

    I've tried following the video and example zip file in the below thread, but I keep getting run-time error messages saying no valid result set. This is even though previewing the query in the genie, displays the results fine.

    Thanks

    I still had the stored proc in MySQL, but I didn't have the grid for some reason. So I grabbed the grid from that other post and ran it and there were no issues... all worked fine.

    You'd need to post your grid and your SP... there must be something else going on.

      I gave up on basing grids on stored procedures opting to base them on views.
      It means I don't need to mess around with the extra events to get the grids working properly.

        Re: Grid based on MySQL stored procedure example

        Thanks. I won't be able to post my stored procedure for anyone to look at, due to the complexity and sensitivity of our data. The main reason for wanting to use a grid is the preferred option of having a row expander to show a child grid. I also wanted to use a stored procedure for performance, as it can run faster due to it being parameterised.

        I was hoping to get hold of another working example, as yes the extra events may be what is causing the issues.

          I would suggest building the simple table used in the example and testing with that. If that works for you (as it does here) then your issue is elsewhere.

            Re: Grid based on MySQL stored procedure example

            I experimented with a stored procedure within a very large multi panel viewbox app, one of the panels was originally based on a view and could take about 16 seconds to load/update as the argument that filtered it changed, with a stored procedure this is now down to just over one second so I am now looking at using as many stored procedures as I can throughout this particular app.

            Of course within a viewbox you have the ability to create a 'row expander' type form to show the child records which, in my opinion, looks a lot better than a grid.
