ToolkitPro MFC version 12.0.0:
I built a simple MFC application, just run it and immediatly close. In my VS2008 IDE the output shows some memory leaks that are related to command bars structure. Here's the relevant output:

Codejock ToolkitPro Terminating!

The line I'm actually focused on is follows:

c:\programmi\codejock software\mfc\xtreme toolkitpro v12.0.0\source\commandbars\xtpcommandbar.cpp(198)

I included <XTToolkitPro.h> in stdafx.h, derived MainFrm class from CXTPMDIFrameWnd and in MainFrm.cpp file I modified

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

function by adding the code block I copied here:

if ( !InitCommandBars() ) return -1;

CXTPCommandBars  *commandBars_p  = GetCommandBars();  // Get Command Bars
CXTPCommandBar   *commandBar_p   = commandBars_p->Add("My Command Bar", xtpBarTop);  // Add Command Bar
CXTPControl      *control_p      = commandBar_p->GetControls()->Add(xtpControlSplitButtonPopup, 20000);  // Add new Split Button Popup to the command bar
CXTPControlPopup *controlPopup_p = static_cast<CXTPControlPopup *>(control_p);  // cast to CXTPControlPopup
CXTPPopupToolBar *popupToolBar_p = CXTPPopupToolBar::CreatePopupToolBar(commandBars_p);  // Create Popup ToolBar
popupToolBar_p->SetTearOffPopup("Popup ToolBar", 20002);  // Set PopupToolBar as Tear Of
controlPopup_p->SetCommandBar(popupToolBar_p);  // Link CXTPControlPopup to PopupToolBar

CXTPControl      *control2_p     = popupToolBar_p->GetControls()->Add(xtpControlButton, 20001);
control2_p->SetCaption("Control 2");  // Add Button to the PopupToolBar

I checked CXTPCommandBar destructor (xtpcommandbar.cpp lines 201 and following) and Command Bar titled "My Command Bar" is correctly deleted. But I can not find deletion of the CXTPPopupToolBar I created with
CXTPPopupToolBar::CreatePopupToolBar method.

I'm not sure if it's me not deleting correctly something or if something is missing in Codejock code.
Can somebody help me?

Hi,

yes, after you link popupToolBar_p to controlPopup_p you have decreate reference counts:

controlPopup_p->SetCommandBar(popupToolBar_p);

popupToolBar_p->InternalRelease();
