You have to pass flAllocationType as MEM_COMMIT|MEM_RESERVE

TCHAR* pBuffer = NULL;
pBuffer = (TCHAR*)::VirtualAllocEx(m_hCplProcess, NULL, MAX_PATH, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);

LVFINDINFO* pInfo = NULL;
// Do VirtualAllocEx for pInfo  ...
pInfo->flags = LVFI_PARTIAL | LVFI_STRING; // <-- crash.

I also tried to VirtualAllocEx a LVFINDINFO object to replace the local one. It crashed too but at different line. Not at FindItem call but at the line

3. create local object of LVFINDINFO.
4. Set the flags and psz as the memory of the remote process
5. Allocate another memory in the remote process, who's size = sizeof( LVFINDINFO).

class A
{
    CDialog* m_pDlg;

public:
    A()
    {
        m_pDlg = new CDialog(IDD_MYDLG);
        m_pDlg->Create(IDD_MYDLG);
    }

    ~A()
    {
        delete m_pDlg;
    }

    void One()
    {
        // Can access m_pDlg here.
    }

    void Two()

        // Can access m_pDlg here.
