What platform defines you have in stdafx.h ? Are you sure youdin't change it to Vista ?

#if _MSC_VER > 1200

// Modify the following defines if you have to target a platform prior to the ones specified below.
// Refer to MSDN for the latest info on corresponding values for different platforms.
#ifndef WINVER              // Allow use of features specific to Windows 95 and Windows NT 4 or later.
#define WINVER 0x0400       // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
#endif

#ifndef _WIN32_WINNT        // Allow use of features specific to Windows NT 4 or later.
#define _WIN32_WINNT 0x0400     // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
#endif

#ifndef _WIN32_WINDOWS      // Allow use of features specific to Windows 98 or later.

I'm upgrading code from v. 11.2.1 to 12.0.1, and I now get a crash error when creating a new property grid (same exact code):

 

int CAVPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CWnd::OnCreate(lpCreateStruct) == -1)
return -1;
// PROPERTY GRID
m_wndPropertyGrid = new CXTPPropertyGrid(); // <---crash
if (!m_wndPropertyGrid->Create( rc, this, IDC_PROPERTY_GRID) )
{
AfxMessageBox(_T("Error creating propertygrid."));
}
else
...

 

Crash ocurrs in CXTPPropertyGrid constructor at:
