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.

    Zero Length String Error When Submit to MS Access

    I have fields for which a value is NOT required. If a user enters something in one of those fields in Alpha, and THEN clears it out, I get an error, when submitting, that the field cannot have a zero length string. The error message is from MS Access which is what my back end database is. IF the user does NOT enter anything into an originally empty field when the record opens in Alpha, then that field submits fine with no error from MS Access. I am assuming that since the user entered something and then took it out, the field somehow now has a zero value string in it instead of being empty or null?????

    Has anyone had any experience with this problem? I need to take care of it because it means that the user ends up with no way of fixing the problem except by canceling edits, which could be annoying. I was attempting to create a button for 'Clear Field' that set the value to null or blank, but can't find the right code to accomplish this.

    Thanks for any suggestions on this.

    Just got all excited because I spotted the field property 'Treat Blank as Null' and I thought that would be the answer. Just tested it, though, and that didn't help...

      Carol,

      In the grid Update Settings, set Blank is Null to on.

      I was able to duplicate your error and this solves it.

        In trying again, turning on Blank is Null in the field Update settings did work. Thank you!
