i realized what the problem was ...

on project properties there was a non standard option checked:

in c++ / code generation / struct member alignment - there was 1 byte (zp1) instead of Default..

i lost three days around that trivial thing, damn...

thank you guys anyway for your suggestions...

All seems ok... one thing can be problem.

try to replace

 m_PropertyGrid.Create( CRect(0,0,0,0), AfxGetMainWnd(), 0);

to

 m_PropertyGrid.Create( CRect(0,0,0,0), this, 0);

because AfxGetMainWnd() will return NULL in CMainFrame::OnCreate..

May be you can isolate the problem with new sample and attach it here?

Hi,

Using DCRT libraries and performing some memory checks

(     // Turn on the full heap checking
    _CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF       |
                      _CRTDBG_CHECK_ALWAYS_DF    |
                      _CRTDBG_DELAY_FREE_MEM_DF  |
                      _CRTDBG_LEAK_CHECK_DF       ) ;

, i realized that the problem comes when allocating a propertygriditem :

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{

  // gas tt
 ASSERT ( _CrtCheckMemory ( ) ) ;

 // ********************* Main Frame
 if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
 {
  TRACE("Failed to create FrameWindow\r\n");
  return -1;
 }
 m_PropertyGrid.Create( CRect(0,0,0,0), AfxGetMainWnd(), 0);
 CXTPPropertyGridItem* pFisse = m_PropertyGrid.AddCategory(_T("cat"));
  // gas tt
 ASSERT ( _CrtCheckMemory ( ) ) ;  <---- everything ok at this point

 CXTPPropertyGridItem* child = new CXTPPropertyGridItem(_T("key"),_T("val")); <-- _CrtCheckMemory ( ) complains here !!
 pFisse->AddChildItem(child);
 child->Remove();

Any idea about what causes this problem?

thanx in advance

Hello, roberto

Hmm... may be you can sent backtrace log to see?

Hi all,

i've experienced some problems with PropertyGrid, more precisely i get an exception from the debugger when trying to call Remove from a PropertygridItem object... i looked at the samples and the same code has no problem there... is there any precaution i should take before removing items in a propertygrid ? thanks
