Hi, I guess you will have to wait for an answer from Giacomo Strangolino from Elettra, who is the hdb++ extractor gui expert. He might be on vacation now. At the ESRF, we are using jhdbviewer to visualize data stored in HDB++ and we don't have much experience with Qt GUIs so I'm afraid we can't help you on this one. Cheers, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

giacomos	Hello. Apart from the errors, does the application work? Are you able to fetch data from the database and display it? Giacomo.

# 8 years ago
TCS_GMRT	Hello Giacomo I am not able to start the application itself. While starting the applications itself by using $./qhdbextractor, the above errors come and it gets closed. Thanks and Regards TCS-GMRT TEAM Regards, TCS_GMRT Edited 8 years ago

giacomos	Hello, does it say something else before closing? Which version of QGraphicsPlot/TGraphicsPlot are you using? Did you check out the main trunk version? Giacomo

# 8 years ago
giacomos	Could you please throw away qgraphicsplot and rebuild it fetching it now from svn checkout svn://svn.code.sf.net/p/tango-cs/code/gui/qgraphicsplot qgraphicsplot and then do the same for TGraphicsPlot also: svn checkout svn://svn.code.sf.net/p/tango-cs/code/gui/tgraphicsplot tgraphicsplot and let me know.

TCS_GMRT	Hello Giacomo I have taken the code of qgraphicsplot from svn itself. I have not build the tgraphics plot. I have attached the image file of how the error comes. I am building with qmake-qt4. Regards, TCS_GMRT Edited 8 years ago Attachments:

giacomos	Ok, you need to edit a configuration file, as the dialog window says. Inside the main distribution folder, you should find two examples, dbconfig and db++config files. They are provided as examples to use for old hdb or new hdb++. Have a look, edit them putting the correct information about database host name and user and password and try again. Giacomo.

TCS_GMRT	Hello Giacomo The correct options have been provided in configuration files. Database host, database user name , db name, db password all are correct. Thanks and Regards TCS-GMRT TEAM Regards, TCS_GMRT
