Seems to != is. You have a memory corruption bug elsewhere
Hy all,
i have a problem since VC.NET 2005 in an exististing CAxDialogImpl<...>
app.
While creation with any AX control (e.g. Microsoft Forms 2.0.TextBox) on
the dialog the app while throw an assertion in malloc.h , line 245
"Corrupted pointer passed to _freea"
called from AtlAxWindowProc2 from destructor of spName
Assertion is only thrown on static ATL linkage - not on linkage to
ATL80.DLL
But probramm seems to be running o.k. if assertion are ignored.
Has anybody an idea, how to solve this?
My settings in stdafx.h:
#define STRICT
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400
#endif
#define _ATL_APARTMENT_THREADED
#ifndef WINVER
#define WINVER 0x0400 // We ar backward compatible
#endif
#include <atlbase.h>
#include <atlapp.h>
extern CAppModule _Module;
#include <atlcom.h>
from atlhost.h (nLen is actually getting 0 in that call):
static LRESULT CALLBACK AtlAxWindowProc2(HWND hWnd, UINT uMsg, WPARAM
wParam, LPARAM lParam) {
switch(uMsg)
{
case WM_CREATE:
{
// create control from a PROGID in the title
// This is to make sure drag drop works
::OleInitialize(NULL);
CREATESTRUCT* lpCreate = (CREATESTRUCT*)lParam;
int nLen = ::GetWindowTextLength(hWnd);
CAutoStackPtr<TCHAR> spName((TCHAR *)_malloca ((nLen + 1) *
sizeof(TCHAR))); ....
}
