Hi Brian,
thanks for your reply. To learn QT4 a little, I created a little and very
stupid test program which is supposed to open 2 sqlite3 databases. They were
created with libdbd-sqlite3-perl and I can work with the sqlite3 binary on
them.
When I run the QT test program, it throws out the error:
"unsupported file format Unable to fetch row". The database does connect ok,
but finds no tables, and the queries all fail.
Any help would be greatly appreciated. It might well be my fault.
Source code below, very crappy, debugging state.
Thanks in advance.
Martin
