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.

    rv._detailViewRecord subelement not found in CanDeleteRecord event result.Cancel =.t.

    I've spent a ton of time trying to figure out why I'm getting this error and am lost. I do have a lot to learn but I think I've tried to debug this pretty thoroughly (at least to the best of my knowledge!). I'm using Alpha Five/11.0 Build/3670-4156. I have a grid component with detail view that I built a year or so ago. I put some code in the CanDeleteRecord server-side event that was working well. It seemed like this problem cropped up after I put on a build (I think the one before this last one). It happens in Working Preview and Firefox, but not IE. I get this error when I try to delete a record: rv._detailViewRecord subelement not found. I ended up stripping everything out of CanDeleteRecord except for result.Cancel = .T. and it still returns the error! I have stripped everything out of my component (I have a backup) except one table, a few fields, and no extra code and I still get the error! If I create a new component based on the dbf table and put the result.Cancel = .T. in the CanDeleteRecord event, it doesn't give the error. I don't understand what Alpha Five does exactly with how it generates the code, but it seems to me like some code was generated in the past which is generated differently now. Is that true? I don't want to have to rebuild my component because there's a lot to it and I'm afraid I'll miss something. Any ideas?

    Re: rv._detailViewRecord subelement not found in CanDeleteRecord event result.Cancel

    After many more hours building, stripping, and rebuilding this component, I finally isolated the problem. It's the Pre-fetch Data for Detail View setting in Properties. This is what I found in the help files:

    Pre-fetch data for Detail View V7 If you choose this option, it will take a little longer for the page to display initially, but then the Detail View will display immediately (without a server round trip). Your browser will use JavaScript to populate the Detail View from the pre-fetched data.
    Note : This feature does not support link and image type controls in the Detail View.
    tmpl.DetailView.PopulateUsingJavaScript as L

    I do have link controls in the detail view to load email messages and that must be what caused the problem. I put this out here for others searching. I don't understand how to debug this kind of problem in a way that doesn't take 10-15 hours. If anyone has any insight I would appreciate it. The error message didn't help me all.
