ODBC with VISUAL BASIC applications to access POSTGRESQL db on LINUX?? "Justin Long" <justinlong@mail.strategicnetwork.org>
I have been using BC++ Builder for a few weeks now to build an interface to a PostgreSQL database via the pgODBC Win32 driver, and there seems to be some incompatibility between the two. Particularly, BCB and programs created with it will frequently result in an access violation in KERNEL32.DLL. The BCB user community does not report such behavior with other ODBC drivers, but there was mention of something similar with an older "buggy" driver for MS-SQL or something along those lines. Example: 1. Open data source + table in BCB-built program 2. Open dialog containing a form and data controls for the data source 3. Immediately jump to last record in table 4. Witness program crash (access violation in kernel32.dll) [This happens after a pause of a few seconds, during which the program displays the "waiting for SQL" mouse pointer.] However, if between steps 2 and 3 you browse though the records in the table, then jumping to the end does not crash the program. Further, there are some tables for which the crash never happens, but I cannot find any pattern for determining whether or not a particular table will cause it. The problem also affects actions such as filling a combo box with the contents of a table. Again, for some tables, the combo box will fill just fine, and for others it will crash. Any ideas? Geoff
