    Please provide a small, complete, compilable and runnable sample program. We can have a look if and where it crashes ourselves then.

        I think that any file sharing hosting will be suitable. For example try http://rghost.net/

          look for a file hoster (e.g. gitorious.org, but you need a logon) or any other

            I have discovered a problem know that is a little confusing.

            When I try to append a Object or a struct thats not in the class where the vector is the program crashes but when I put a struct inside the class and append this to the vector it works fine

                Your code works without any crashes. I didn't do any changes though.

                    toho71 either you have to read more about C++ or you did horrible typo. Here it is:
                    @myClass::~myClass()
                    {
                    delete this;
                    }@

                        }@

                        and I got this text in my consol

                            it gonna be big with many files but maybe only the files in the spec region and it will not compile.
                            I'll try

                              You should provide only source files. Do not include object files (and autogenerated moc_, ui_, qrc_*) in the tarball.

                                      it works very well to append objects when I instantiates the object globalParam but later when I try to append some new objects later in the program it seems like the vector isn't there.

                                        Unfortunately I can spend some time on it right now, but the archive is no longer available. Do you mind uploading it again, please?

                                          I got it solved and it had a Nullpointer in another place so this worked fine but some dependent functions made some errors to this.
