Taskpanel using in COM Component gvs erro

Hi,

I am using CXTPTaskPanel in my ActiveX COM Component which is also written in Visual C++. In debug build, Task panel is initialized properly, its very fine till now, but, i am getting wincore.cpp (line 986) [snap attached] debug assertion failure, when I hover on the task panel. What I do is simply popping up the dialog on some event and in that dialog, only one task panel is there. I initialize the task panel through following code.

void CPropGridDlg::InitTaskPanel()   
{
    // TODO: Add your control notification handler code here
   
    //CXTPPaintManager::SetTheme(xtpThemeOffice2003);
    XTThemeManager()->SetTheme(xtThemeOffice2003);
   
    CRect    rectClientArea;
    RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, CWnd::reposQuery, rectClientArea);
   
    CXTPClientRect rc(this);
    rc.top = rectClientArea.top + 5;
    rc.right = 150;
    rc.bottom = rc.bottom - 20;
   
    if (!m_wndTaskPanel.Create(WS_CHILD|WS_VISIBLE|WS_CLIPSIBLINGS| WS_CLIPCHILDREN, rc, this, IDD_PROPGRID_DIALOG))
    {
        MessageBox("Failed to create..");
    }
   
    //m_wndTaskPanel.SetTheme(xtpTaskPanelThemeNativeWinXPPlain) ;
    //m_wndTaskPanel.SetTheme(xtpTaskPanelThemeNativeWinXP);
    m_wndTaskPanel.SetTheme(xtpTaskPanelThemeShortcutBarOffice20 03);
    m_wndTaskPanel.SetOwner(this);
   
    CXTPTaskPanelGroup* pGroupLighting = m_wndTaskPanel.AddGroup(IDS_ABOUTBOX);
   
    pGroupLighting->AddLinkItem(IDS_ABOUTBOX, 0);
    pGroupLighting->AddLinkItem(IDS_ABOUTBOX, 1);
    pGroupLighting->AddLinkItem(IDS_ABOUTBOX, 2);
    m_wndTaskPanel.SetAnimation(xtpTaskPanelAnimationYes);
    m_wndTaskPanel.Reposition(TRUE);
}

The strange is, Task panel is initialized and shown properly but when I hover my mouse on any area of task panel, it gives this debug assertion error. please reply me at the earliest, what should I do to solve this..

I am using Visual Studio 6.0 (visual c++ 6.0)..

The debug assertion error I am getting is,

Following is the call stack.. If i put the same thing in my dialog based application its working. Just in activeX control its not working and in activeX too, its giving debug error while hovering the mouse over the task panel area, till that time its perfect.

 // TODO: Add your control notification handler code here
 XTThemeManager()->SetTheme(xtThemeOffice2003);
 
 CRect rectClientArea;
 RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, CWnd::reposQuery, rectClientArea);
 
 CXTPClientRect rc(this);
 rc.top = rectClientArea.top + 45;
 rc.right = 140;
 rc.bottom = rc.bottom - 40;
 
 if (!m_wndTaskPanel.Create(WS_CHILD|WS_VISIBLE|WS_CLIPSIBLINGS| WS_CLIPCHILDREN, rc, this, IDD_WC_PRINTPREVIEW_DLG))
 {
  MessageBox("Failed to create..");
 }
 
 m_wndTaskPanel.SetTheme(xtpTaskPanelThemeShortcutBarOf fice2003);
 m_wndTaskPanel.SetOwner(this);
 
 CXTPTaskPanelGroup* pGroup3DText = m_wndTaskPanel.AddGroup(IDS_WC_PP_GROUP_MARGINS);
 
 pGroup3DText->AddTextItem("Left");
 m_LeftMarginEdit.Initialize(this);
 m_LeftMarginEdit.SetParent(&m_wndTaskPanel);
 pGroup3DText->AddControlItem(m_LeftMarginEdit);

 pGroup3DText->AddTextItem("Right");
 m_RightMarginEdit.Initialize(this);
 //m_RightMarginEdit.SetParent(&m_wndTaskPanel);
 pGroup3DText->AddControlItem(m_RightMarginEdit);

 pGroup3DText->AddTextItem("Top");
 m_TopMarginEdit.Initialize(this);
 //m_TopMarginEdit.SetParent(&m_wndTaskPanel);
 pGroup3DText->AddControlItem(m_TopMarginEdit);

 pGroup3DText->AddTextItem("Bottom");
 m_BottomMarginEdit.Initialize(this);
 //m_BottomMarginEdit.SetParent(&m_wndTaskPanel);
 pGroup3DText->AddControlItem(m_BottomMarginEdit);

Can you tell me why it is happening ?

 

I think following information will be helpful to you..

Following are the lines debugger shown to me while breaking at assertion,

Now, providing you with call context..
