Building a C++ application using QIntValidator and QDoubleValidator using KDevelop. These validators work with KLineEdit widgets after fixing some errors in their usage.
There is a properties dialog with a large number of input fields as follows:
Here is the header definition for the data.

Work continues with SUSE 10.1 Linux both in configuring the system and in learning to use the KDevelop IDE for C++ programming.
Work continues with SUSE 10.1 Linux both in configuring the system and in learning to use the KDevelop IDE for C++ programming. There are several interesting items to mention:
After building an application in Debug configuration, switching to optimized has corrupted the project so that it will no longer build.
SUSE 10.1, KDevelop 3.3.3, KDE 3.5.1
Developed the program under the debug configuration and then tried to switch to default or optimized configuration. Tried many combinations to try to get it working again, but all BUILD options give errors ending with makedistclean.

Permissions problem kept php5 and mysql 5 from talking….
When setting up a test website using Apache 2, php5 and mysql5, the connection to the database failed with AccessDenied. If the password were removed, then the failure looked different. The resolution to the problem is to include localhost explicitly in the host list and set database privileges for localhost. The default is @% which is wildcard, but apparently wildcard does not include localhost.
For a complete description, screen shots and the whole story:

My first real linux program using KDevelop and QT works.
Using KDevelop 3.3.3 on SUSE 10.1 I’ve ported one of my WinMFC programs to Linux. The GUI is written with the QT3 tool kit and QTdesigner in KDevelop.
When the program is running the appropriate buttons are disabled and the program saves and restores the configuration [interval and Watch on Start] and the site list.
Update: You can find the modern version of the program here.
Here are some comments on the Linux apps that I’ve started using.
Linux is very culturally compatible with WinXP. Here are some comments in some random order: Click on pictures for a larger view.
Experiences after using Linux for a few days and having solved most of the problems.
This is from an email to a friend about the saga so far in installing and learning Linux.
A few snags with Linux along the way:

Here is some sound card info for my sound card that doesn’t work.
(RESOLVED. For reasons unknown, the sound card has begun to work. Selecting the mixer other than ALSA seems to have helped.)

Experiences installing SUSE Linux 10.1 for the first time.
While I’ve been a software engineer for years and have used *nix systems for some of those years, I’ve never installed or used Linux before. I started my foray into this subject by installing SUSE 10.1 on a DELL WS 410:
This system has been running Win XP Pro quite nicely. Performance has actually been quite good and this system is very usable under windows for document prep, C++ programming using Visual Studio 6 and web browsing.

I’ve taken some panoramas of the South Slough National Estuarine Research Reserve ( SSNERR ). The SSNERR is a tidal wetlands park and research station in Charleston, OR. The park is about 5000 acres.
The skunk cabbage is in full leaf, although by now the flowers are all gone. Don’t forget to click on the pictures for a full size image. The images are about 6000 pixels wide in full size. If rendered at highest quality, some of these pictures would be over 20,000 pixels wide.
More information on the SSNERR and the entire NERR system can be found here: SSNERR home page
enjoy.
