Overflow while converting variant of type (LongWord) into type (Integer). |

Richard Harding | Tim,
Using EDB 2.02b8 with Delphi 2007. A customer sent this bug report. I have sent out a very small demonstration database that has been used by a number of potential customers. This one customer has this overflow error on start of program. The other customers of all OK with an identical DB. Any idea what could be creating this?

I just tried a Locate in the EDB Manager (Open Table..Search for Row) on an Integer column with the value 4294967295 and I got the proper error: ElevateDB Error #1011 An error occurred with the value 0 (The value is out of the range of permissible values for the Integer type) (the 0 value in the message is a mistake and will be corrected) Are you using Delphi 5, perhaps ? -- Tim Young Elevate Software www.elevatesoft.com |

Richard Harding | Tim,
The problem was caused by trying to store the HardwareID which is a DWORD (or LongInt) into an Integer field and this one person had a HardwareID which had the high order bit set. If the high order bit is set on the HardwareID, I make it a negative number and all is well. Richard Harding |

I'll still check it out, though, and see if I can replicate the overflow situation, which shouldn't happen. -- Tim Young Elevate Software www.elevatesoft.com |
