请问afxwin1.inl Line:24 是什么错误？

我用HOOK在记事本下弹出对话框时出现Assert错误
afxwin1.inl Line:24

错误信息：afxwin1.inl
line22
解决方法是在新建窗体前加上AFX_MANAGE_STATE(AfxGetStaticModuleState());

FDT_DLLEXPORT void DragPanel()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
AfxEnableControlContainer();
AfxOleInit( );
CDragPanel *pPanel=new CDragPanel;
// if(m_hWnd)
// {
//m_pCtrlSite->Create();
pPanel->Create(IDD_DRAGPANEL);
pPanel->ShowWindow(1);
// }
}

gdiplus::bitmap* cutimage(gdiplus::image* source,int x,int y,int width,int height) { gdiplus::rect zoomrect(0, 0, width,height); gdiplus::bitmap* pimagescale_ = new gdiplus::bitmap(zoomrect.width, zoomrect.height); gdiplus::rectf rf(x,y,width,height); gdiplus::texturebrush brush(source,rf); gdiplus::graphics graphicsscale(pimagescale_); graphicsscale.fillrectangle(&brush, zoomrect); return pimagescale_; }
