窗户框架因滥用螺纹而挂起

我正在wxListCtrl中获取数据库表值((数据可能很大，所以我正在使用wxThread)子线程将行发送到Main线程，并且主线程将其填充到wxListCtrl中， 一切都很好，但是当我尝试关闭框架时，这给了我意外的结果.在关闭按钮上，我正在调用一个新框架，有时它打开，而有时没有，我的代码是:-

I am getting a database table value in wxListCtrl, (data can be large so I am using wxThread) Child thread send row to Main thread and main thread fill it in wxListCtrl, everything is going good but when I m trying to close the frame , it is giving me unexpected result. at the close button , I am invoking a new frame, sometime it opens and some time not, my code is:-

 if(thread_object_holder->IsAlive())
        {
            wxPuts(wxT("live"));
            thread_object_holder->Pause();
            wxMessageDialog *msg = new wxMessageDialog(this,wxT("You want to quit"), wxT("Quit Login Report") ,wxYES_NO | wxNO_DEFAULT | wxICON_QUESTION);
            if ( msg->ShowModal() == wxID_YES )
            {
                thread_object_holder->Delete();
                temp_back_frame *obj= new temp_back_frame();
                this->Destroy();
                obj->Show(true);
            }
            else
            {
                thread_object_holder->Resume();
            }
        }
        else
        {
            wxPuts(wxT("dead"));
            wxMessageDialog *msg = new wxMessageDialog(this,wxT("You want to quit"), wxT("Quit Login Report") ,wxYES_NO | wxNO_DEFAULT | wxICON_QUESTION);
            if ( msg->ShowModal() == wxID_YES )
            {
                thread_object_holder->Delete();
                temp_back_frame *obj= new temp_back_frame();
                this->Destroy();
                obj->Show(true);
            }

        } 

表中只有7行，在填充记录期间，如果我按一下按钮，那里一切都很好，但是一旦将7行放入ListCtrl {我认为现在线程将被破坏}，我就没有数据可放入listctrl，我们按下关闭按钮，然后有时打开新框架，有时挂起，我认为这种情况是负责的，但在这里我采取了适当的预防措施来处理这种情况，请告诉我，我哪里错了.

there are only 7 row in table, during the filling record if I press the button, everything is fine there but once 7 row placed in ListCtrl { I think now thread will be destroy } , me no data to put to listctrl, we press close button then sometime new frame open, some time frame hang, I THINK THREAD IS RESPONSIBLE FOR THIS BUT HERE I TAKE PROPER PRECAUTION TO HANDLE THE THREAD, please let me know, where I am wrong.
