    You should start by reading tutorials and examples bundled with the documentation. Once you get a grip of things, you can use Qwt for your histogram or implement your own custom widget, your usecase seems very simple.

    I'm sure the tutorial didn't tell you to link with QAxServerd.lib. You must have done something wrong. Did you use qmake to manage your project?

    Hi wysota,

    I am found the problem already..

    I am using vs2005 to create the Qt project. Previously, During the project setting I have include the ActiveQt server library and ActiveQt container library. Then i got the error msg about missing LIB file.

    Just now I recreate a new project without include these 2 library then no more problem.

    So means i cannot use "qaxserver.lib" or the Qt version I used no need to include the "qaxserver.lib"

    I have find this link http://lists.trolltech.com/qt-intere...ad01572-0.html. After I read it still very confuse with it.

    Thank for you help in advanced

    It means you should use qmake to manage your project. The AxServer is only available in the commercial edition of Qt and it seems you are using the open source one.

    The editor you use has no influence on Qt. Qt with visual studio is exactly the same as Qt with vi.

    This has been discussed at http://labs.trolltech.com/forums/topic/516 - which refers to http://article.gmane.org/gmane.comp....match=activeqt as a defintive source of truth from Thiago Macieira at QtSoftware.

    The labs forum article shows some methods that can be used to compile ActiveQt libraries. I did it by changing one line in a the configure tool source code (and recompiling), and one line in qglobal.h (like in the labs forum). I leave it as an excercise for the reader to figure out what I changed in "configure" (I'm at work so I can't remember it in detail anyway). I haven't tried it yet, but it should work for the Oracle sql driver as well.

    I think the case here is that the library shouldn't be enabled at all, not that it didn't compile Although of course information about ActiveQt being BSD-licenced is a value in itself so thanks for that
