Attempted to read or write protected memory while Appending to File Geodatabase

MeleKoneya — Thu, 07 Apr 2011 15:10:16 GMT

I am using ArcObjects to delete features and append features to a File Geodatabase. The last time this process ran, I got the following error message:

"Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

The Feature Class was corrupt after the processs.

I reran the process in ArcCatalog using ArcToolBox and on the the second attempt, I was able to successfully delete and append features.

Any ideas on what causes this error and more importantly, how to prevent it in the future?

Thanks,

Mele

Hi,

If you have a feature cursor, or selection set you might have the feature class hung up. Try the Marshal.ReleaseComObject(pCursor); to free up your feature class. This sometimes works for me.

Hey,

After reading some more forums, I think you should use the ComReleaser rather than the marshall.ReleaseCom();
