Hi,

I am trying to read contents from Windows Address Book using the following code.

Qt Code: 
  1. #include  <list>
  2. using namespace std;
  3.  
  4. WABImporter::WABImporter(ContactDetails *cd,QWidget *parent) : QDialog(parent),contactDetails(cd)
  5. {
  6. 	setAttribute(Qt::WA_DeleteOnClose);
  7. 	setWindowTitle(tr("Windows Address Book"));
  8.  
  9. 	cWAB = new CWAB("");//This object has no Qt code and is used to read from windows address book
  10.  
  11. 	contactData = new ContactData(this);
  12.  
  13. 	splitter = new QSplitter(Qt::Horizontal,this);
  14.  
  15. 	listWidget = new QListWidget(this);
  16.  
  17. 	viewMode = new ViewMode(this);
  18. 	cardArea = new QScrollArea(this);
  19. 	cardArea->setMinimumWidth(300);
  20. 	cardArea->setWidget(viewMode);
  21. 	cardArea->setWidgetResizable(true);
  22. 	cardArea->setFrameStyle(QFrame::Box|QFrame::Plain);
  23.  
  24. 	splitter->addWidget(listWidget);
  25. 	splitter->addWidget(cardArea);
  26.  
  27. 	importCurrentButton = new QPushButton(tr("&Import current contact"),this);
  28. 	importAllButton = new QPushButton(tr("&Import &All"),this);
  29. 	cancelButton = new QPushButton(tr("&Cancel"),this);
  30.  
  31. 	connect(importCurrentButton,SIGNAL(pressed()),this,SLOT(importCurrent()));
  32. 	connect(importAllButton,SIGNAL(pressed()),this,SLOT(importAll()));
  33. 	connect(cancelButton,SIGNAL(pressed()),this,SLOT(close()));
  34.  
  35. 	QHBoxLayout *hLay1 = new QHBoxLayout;
  36. 	hLay1->addStretch(1);
  37. 	hLay1->addWidget(importCurrentButton);
  38. 	hLay1->addWidget(importAllButton);
  39. 	hLay1->addWidget(cancelButton);
  40.  
  41. 	QVBoxLayout *mainLayout = new QVBoxLayout(this);
  42. 	mainLayout->addWidget(splitter);
  43. 	mainLayout->addLayout(hLay1);
  44.  
  45. 	setLayout(mainLayout);
  46. 	setMinimumSize(640,480);
  47.  
  48. 	populateContactsList();
  49. }
  50.  
  51. WABImporter::~WABImporter()
  52. {
  53. 	cWAB->ClearWABLVContents();
  54. 	delete cWAB;//This crashes the application
  55. }
  56.  
  57. void WABImporter::populateContactsList()
  58. {
  59. 	list<string> contactsList;
  60. 	if(cWAB->LoadWABContents(contactsList)){
  61. 		list<string>::iterator listIterator;
  62. 		for(listIterator = contactsList.begin(); listIterator != contactsList.end(); ++listIterator){
  63. 			listWidget->addItem(QString::fromStdString(*listIterator));
  64. 		}
  65. 	}
  66. }

There is a menu option, clicking on which will open a dialog box and all the windows contacts are listed there. When I close this dialog the application crahes in

qeventdispatcher_win.cpp

Qt Code: 
  1. Q_CORE_EXPORT bool winPeekMessage(MSG* msg, HWND hWnd, UINT wMsgFilterMin,
  2.                      UINT wMsgFilterMax, UINT wRemoveMsg)
  3. {
  4.     QT_WA({ return PeekMessage(msg, hWnd, wMsgFilterMin, wMsgFilterMax, wRemoveMsg); } ,
  5.           { return PeekMessageA(msg, hWnd, wMsgFilterMin, wMsgFilterMax, wRemoveMsg); });//Crashes here
  6. }

Another very strange thing is that it crahses only when I put a break point in the destructor i.e. delete cWAB and try to debug from there.

Otherwise, when I close the dialog, nothing happens but crashes when I close the main application window.

The main application window crahes in qwidget.cpp

Qt Code: 
  1. void QWidgetPrivate::hide_helper()
  2. {
  3.     Q_Q(QWidget);
  4.     if ((q->windowType() == Qt::Popup))
  5.         qApp->d_func()->closePopup(q);
  6.  
  7.     // Move test modal here.  Otherwise, a modal dialog could get
  8.     // destroyed and we lose all access to its parent because we haven't
  9.     // left modality.  (Eg. modal Progress Dialog)
  10.     if (q->isModal())
  11.         QApplicationPrivate::leaveModal(q);
  12.  
  13. #if defined(Q_WS_WIN)
  14.     if (q->isWindow() && !(q->windowType() == Qt::Popup) && q->parentWidget()
  15.         && !q->parentWidget()->isHidden() && q->isActiveWindow())
  16.         q->parentWidget()->activateWindow();        // Activate parent
  17. #endif
  18.  
  19.     q->setAttribute(Qt::WA_Mapped, false);
  20.     hide_sys();//CRASHES HERE
  21.  
  22.     bool wasVisible = q->testAttribute(Qt::WA_WState_Visible);
  23.  
  24.     if (wasVisible) {
  25.         q->setAttribute(Qt::WA_WState_Visible, false);
  26.  
  27.     }
