<p class=MsoNormal><span style='color:black'>Hi Michael,<br>
<br>
As far as I know, we only tested the data exchange interface with one single
.dcm file yet. I am also not aware of any restrictions regarding the QtSoap
array support (apart from a max dimension of 5).<br>
<br>
How are you updating the AvailableData structure? Could you send the SOAP
messages send by the client and received by the server (you might have to edit
/opt/git/CTK/Plugins/org.commontk.dah.core/ctkSoapLog.h to enable logging).<br>
<br>
Maybe Ivo and Benoit can also comment on this issue, they where mainly involved
in writing the data exchange interface.<br>
<br>
Thanks,<br>
Sascha<br>

framework from inside your own application and this is also the preferred way
(instead of modifying the existing CTK plug-ins directly). In the case of a
DICOM App, I can think of two different approaches, depending on your
requirements:</span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";

equivalent to org.commontk.dah.exampleapp, which contains all your app code

framework, but should also be easy to achieve. What the
org.commontk.dah.exampleapp plug-in actually does, is to register a class
containing the DICOM "application logic" as a service within the
plugin-framework. You could either create this class (similar as the
ctkExampleDicomAppLocig class) inside your current project (not in a separate
plug-in) and register an instance by using the plugin framework context, or
create a small plug-in containing this class and taking care of the
registration itself. Then start the plugin framework from inside your
executable, if you recognize the host and app url command line parameters
(otherwise, create a QMainWindow yourself).</span><span style='font-size:10.0pt;
