Why do I get 80020005 errors?
There are several variations of the 80020005 error. Here are a few of them:
This is typically an error coming from a custom COM object / component. One way around it is to re-write the object using ObjectContext, instead of onStartPage / onEndPage (which are deprecated as of the release of Windows 2000).
This can happen if you try to set a date column to a value that is not in proper date format, e.g. "UPDATE tableName SET dateColumn='31/31/2002'"... it can also happen when using a command object and named constants (e.g. adDate and adLongVarChar); I will always recommend using a straight EXEC statement against a connection object, rather than go through the hassle and rigorous code required by an ADODB.Command object.
This can happen if you try to response.write an array, or data coming out of a blob / ole / image column, or response.binarywrite non-binary data. To get around the blob scenario, you can upgrade to the latest MDAC (MDAC Download Page), which allows you to avoid the GetChunk / AppendChunk methods. See KB #258038 for (admittedly VB-based) samples of avoiding GetChunk and AppendChunk, and KB #276488 for sample code using ADODB.Stream to send binary data to the browser...
Another scenario is using a COM object to response.binarywrite large image data. For example, I've seen errors with ASPImage when a JPG file was over 575kb (though I don't know why an image that big would ever be on the web, much less in JPG format at all). One workaround would be to use a different object (maybe ADODB.Stream) to output the file; another would be to use smaller files.
Finally, see Article #2099 if neither of the above situations applies to you.
