Multi-monitor programming pitfalls

By Dennis Gurock | August 23, 2005
If you are a .NET, Java or Delphi developer, please take a look at our advanced logging tool SmartInspect.

“I will highlight two problem areas where many programs, including popular ones, make wrong assumptions and therefore contain bugs on multi-monitor machines. In fact, we have been affected by one of these problems ourselves. A customer reported that the SmartInspect Console isn’t restored correctly when it’s closed on a non-primary monitor in maximized state. We tested it, could reproduce the annoyance and wondered why we never noticed it before, especially since we use two monitors, too.”

    Another thing that most programs get wrong is windows task bars. They assume that there will only be 1 and it will be at the bottom of the monitor. You should handle any number of task bars in any possition.

    That’s a good point Joe. We will have to test that with SmartInspect, too.

    I normally do not use multiple task bars so I never noticed any problems with most programs.

    Here is my multi-montior/multi-taskbar desktop.

    Thanks for the screen shot. When I add a second toolbar / taskbar to my Desktop under Windows XP, all programs - including IE, Explorer etc - ignore it and are in front of it when maximized. I tried logout/login but they still ignore it.

    I noticed that your Firefox is maximized and doesn’t hide the second taskbar under Windows 2000. Maybe it’s a bug in XP?

    Set the bar to be "Always on Top".

    My OS is XP Pro, not 2000.
