EBcdException - BCDOverflow

Post by devartfan » Thu 30 Apr 2009 10:34


we have an urgent problem with the TFMTBCDField especially with the property precision.

In design-time, delphi saves the length of numeric fields in the dfm-file.

Database field length-changes at runtime cause the mentioned BCDOverflow.

Are there any suggestions to solve this problem? Is it really neccessary to save field-length in dfm-files?

The driver does not have influence on saving fields to DFM. Probably you can change the Length property of fields at runtime after creating the form to avoid the problem.
