Converting App Issue V3 to V4 |
Mon, Oct 26 2009 8:37 AM | Permanent Link |
"Al Vas" | Hi,
Just playing around and scoping a version change and after upgrading the database from V3 to V4 I receive an error on running the application as follows: EReadError with message 'Error reading TDBISAMFieldDef.Size: Invalid field size' As we have a lot of fields, any ideas which particualr field type might be causing this issue? Thanks Alex |

<< Just playing around and scoping a version change and after upgrading the database from V3 to V4 I receive an error on running the application as follows: EReadError with message 'Error reading TDBISAMFieldDef.Size: Invalid field size' >> Do you get the error when you open the table using the V4 DBSYS utility ? If not, then there's an issue with the field definitions (FieldDefs) for a TDBISAMTable or TDBISAMQuery component, most likely they are stored in the form or data module (StoreDefs=True) and they are not valid for DBISAM 4.x. -- Tim Young Elevate Software www.elevatesoft.com |
