duilib使用中出现CPaintManagerUI地址发生改变的问题

[tauke_wang]

如题，最近在研究DUILIB，写了一个demo，但是在运行时出现RT中的问题，下面是部分代码

LRESULT CHelloDemoWnd::OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
	LONG styleValue = ::GetWindowLong(*this, GWL_STYLE);
	styleValue &= ~WS_CAPTION;
	::SetWindowLong(*this, GWL_STYLE, styleValue | WS_CLIPSIBLINGS | WS_CLIPCHILDREN);

	m_pmUI.Init(m_hWnd);
	CDialogBuilder builder;
	CControlUI* pRoot = builder.Create(_T("HelloDemo.xml"), (UINT)0, NULL, &m_pmUI);
	ASSERT(pRoot && "Failed to parse XML");
	m_pmUI.AttachDialog(pRoot);
	m_pmUI.AddNotifier(this);

	Init();

	return 0;
}

LRESULT CHelloDemoWnd::HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	BOOL bHandle = TRUE;
	LRESULT lRes = 0;
	switch (uMsg)
	{
	case WM_CREATE:
		{
			lRes = OnCreate(uMsg, wParam, lParam, bHandle);
		}
		break;
	case WM_DESTROY:
		{
			lRes = OnDestroy(uMsg, wParam, lParam, bHandle);
		}
		break;
	default:
		bHandle = FALSE;
		break;
	}
	if (bHandle)
	{
		return lRes;
	}
	if (m_pmUI.MessageHandler(uMsg, wParam, lParam, lRes))
	{
		return lRes;
	}
	return CWindowWnd::HandleMessage(uMsg, wParam, lParam);
}

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPSTR /*lpCmdLine*/, int nCmdShow)
{
	CPaintManagerUI::SetInstance(hInstance);
	CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("skin\\HelloDemo"));

	HRESULT Hr = ::CoInitialize(NULL);
	if(FAILED(Hr))
	{
		return 0;
	}

	CHelloDemoWnd* pWnd = new CHelloDemoWnd();
	if (pWnd == NULL)
	{
		return 0;
	}
	pWnd->Create(NULL, _T("HelloWnd"), UI_WNDSTYLE_FRAME, 0L, 0, 0, 0, 0);
	pWnd->CenterWindow();
	pWnd->ShowWindow();

	CPaintManagerUI::MessageLoop();

	::CoUninitialize();
	return 0;
}

class CHelloDemoWnd : public CWindowWnd, public INotifyUI
{
public:
	CHelloDemoWnd();
	~CHelloDemoWnd();

	LPCTSTR GetWindowClassName() const;
	UINT GetClassStyle() const { return CS_DBLCLKS; };
	void OnFinalMessage(HWND /*hWnd*/) { delete this; };

	LRESULT HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam);

	LRESULT OnDestroy(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
	LRESULT OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);

	void Notify(TNotifyUI& msg);
private:
	void Init();
private:
	CButtonUI*	m_pBtnClose;

	CPaintManagerUI	m_pmUI;
};

皮肤XML文件

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>

上面是实现中的主要部分代码，皮肤XML文件是用DuiDesigner做的，CPaintManagerUI中的窗口句柄就是设置的m_hWnd的地址，加载皮肤获取按钮指针都正常，在界面最后显示时出现CPaintManagerUI中的句柄地址改变了，导致异常，请问吧里的大神这是什么原因造成的如何解决？

谁莫名其妙改变，就在谁上面设置数据改变断点。 参考下面：

#include <time.h>
#include <stdlib.h>
#include <windows.h>
int main() {
    int a,b[11];//本来是b[10]，为判断哪句越界，故意声明为b[11]

    srand((unsigned int)time(NULL));//按两次F11，等黄色右箭头指向本行时，调试、新建断点、新建数据断点，地址：&b[10]，字节计数：4，确定。
    while (1) {//按F5，会停在下面某句，此时a的值为10，b[10]已经被修改为对应0..4之一。
        b[(a=rand()%11)]=0;
        Sleep(100);
        b[(a=rand()%11)]=1;
        Sleep(100);
        b[(a=rand()%11)]=2;
        Sleep(100);
        b[(a=rand()%11)]=3;
        Sleep(100);
        b[(a=rand()%11)]=4;
        Sleep(100);
    }
    return 0;
}

CPaintManagerUI中的地址成为了0Xfeeefeee 不知道哪里把地址给改了，但是m_hWnd的地址还是原来的

0Xfeeefeee 是已经free 了的内存, 你设置个数据断点一下就找到了...
