Different behaviour in XP and in Vista...

[Sbleck]

Hello, Mr. Noetscher,

I´m back to KBasic after some time, because noted that now was possible to connect to databases (Oracle, specifically). Well, I downloaded the latest release 1.89 (and recommended it to other VB developer, too). Right after I installed it in one machine with Windows Vista, I could generate an executable (having my own license) without any problems and as expected. But when I tried to check if the KBasic IDE could run in Windows XP (Pro), the process of compilation hangs (only the projects folder are created, without any other files inside it...).

Is there any requirement for running in Windows XP ? I checked the documentation and couldn´t understand why that happened in XP and not in Vista. Any advice should be greatly appreciated, of course too...

Please let me know too how could I do to connect to Oracle (and SQL Server) databases, too...

Regards,
Sven

Downloaded latest version and this one is running fine.
No error's on native Windows XP and Windows XP / VirtualBox

Hi Sven,
there is a need for a Qt db driver to connecting to Oracle and sql server and as far as I know, there are available only for Qt license holders and not the LGPL version of Qt.

Hello, Bernd,

Thanks for your comments. Only recently I had chances to understand why:

"
The QtSql module provides a platform- and database-independent interface
for accessing SQL databases. This interface is supported by a set of classes
that use Qt’s model/view architecture to provide database integration with the
user interface.

A database connection is represented by a QSqlDatabase object. Qt uses drivers
to communicate with the various database APIs. The Qt Desktop Edition
includes the following drivers:

Code: Select all

Driver   Database
---------------------------------------------
QDB2     IBM DB2 version 7.1and later
QIBASE   Borland InterBase
QMYSQL   MySQL
QOCI     Oracle (Oracle Call Interface)
QODBC    ODBC (includes Microsoft SQL Server)
QPSQL    PostgreSQL versions 6.x and 7.x
QSQLITE  SQLite version 3 and later
QSQLITE2 SQLite version 2
QTDS     Sybase Adaptive Server


Due to license restrictions, not all of the drivers are provided with the Qt Open
Source Edition. When configuring Qt, we can choose between including the
SQL drivers inside Qt itself and building them as plugins. Qt is supplied with
the SQLite database, a public domain in-process database.

C++-GUI-Programming-with-Qt-4-1st-ed, pg 283.
http://www.qtrac.eu/C++-GUI-Programming ... 1st-ed.zip
"

And I know that even Oracle databases could be accessed by open source drivers (http://otl.sourceforge.net/), but couldn´t understand why it couldn´t be added to some tools, in the meanwhile...

But I should say that in XP the problems (hang during compile process) remain the same, during compilation. Wanted to understand why, of course...

Rgds,
Sven

Did have XP until last autumn 2009, and never experienced problems you told us. Unfortunetaly, I am running only Windows 7 by now. So no chances of fixing.
Does the problem occurs with every example?

@Ts and Bernd,
I'm willing to test it, still running XP.
So Sven can you tell which example(s) are giving you problems ?
