I have a dbf that won't allow me to add or delete any fields. When I try to save after change, I get an 'out of memory' error. The dbf was originally created on XP/32 and has been brought over to Win7/64 PC. However, other similar databases do not have this problem. Anyone know what the problem might be?

Alpha Software strives to create an environment where all members of the community can feel safe to participate. In order to ensure the Alpha Software Forum is a place where all feel welcome, forum participants are expected to behave as follows:
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
Moderators may also rename posts and threads if they are too generic or do not property reflect the content.
Moderators may move threads if they have been posted in the incorrect forum.
Threads/Posts questioning specific moderator decisions or actions (such as "why was a user banned?") are not allowed and will be removed.
The owners of Alpha Software Corporation (Forum Owner) reserve the right to remove, edit, move, or close any thread for any reason; or ban any forum member without notice, reason, or explanation.
Community members are encouraged to click the "Report Post" icon in the lower left of a given post if they feel the post is in violation of the rules. This will alert the Moderators to take a look.

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.
- Be professional in your conduct
- Be kind to others
- Be constructive when giving feedback
- Be open to new ideas and suggestions
- Stay on topic
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
- Spam.
- Vulgar language.
- Quotes from private conversations without permission, including pricing and other sales related discussions.
- Personal attacks, insults, or subtle put-downs.
- Harassment, bullying, threatening, mocking, shaming, or deriding anyone.
- Sexist, racist, homophobic, transphobic, ableist, or otherwise discriminatory jokes and language.
- Sexually explicit or violent material, links, or language.
- Pirated, hacked, or copyright-infringing material.
- Encouraging of others to engage in the above behaviors.
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
- Remove the Post or Thread - the content is removed from the forum.
- Place the User in Moderation - all posts and new threads must be approved by a moderator before they are posted.
- Temporarily Ban the User - user is banned from forum for a period of time.
- Permanently Ban the User - user is permanently banned from the forum.
Moderators may also rename posts and threads if they are too generic or do not property reflect the content.
Moderators may move threads if they have been posted in the incorrect forum.

Re: out of memory error
I've seen that error when a function is called without the proper parameters passed to it.

Re: out of memory error
Originally posted by jas102 View PostYes, so far as I know, I brought over all support files. When trying to Pack, I get a 'cannot open table' error and then I can't do anything with the dbf until I close A5 and reopen it.
Check that table and see if it has the same problems.
Then delete the problem table and rename the duplicate table.Al Buchholz

Re: out of memory error
Originally posted by jas102 View PostTried this and the problem follows to the duplicated database. And, when I get the out of memory error, I lose the right click ability. Something is corrupt but I cannot identify. Any other thoughts? I noticed some of my memo fields items are showing on wrong items in the dbf. Could corrupt memo field cause this??
empty the table and see if the problem goes away.
Is the data needed in this table or are you starting over?
When is the last good backup of this table?Al Buchholz

Re: out of memory error
Originally posted by jas102 View PostI believe I found the problem - corrupt memo field. I was able to export the field data, delete the field, save the dbf, re-create the field, and seems OK right now. Will now attempt to import back the memo field data.
Imported from pointers that are pointing at the wrong data will retain the wrong data.
But you know and see your data better than anyone else.Al Buchholz

Originally posted by jas102 View PostYes, the exported memo data is a mess - attached to wrong records. I will have to recreate by hand rather than import it. Not that many. Thanks for your thoughts on all this, Al.
I've dealt with it with Foxpro databases for a long time.
It's not just an Alpha issue.
And don't tell anyone else, but SQL databases can get corrupted too. Just happens rarely and the recovery is usually easier. But not always.Al Buchholz
