Duilib程序中出现pRoot为NULL,调用xml失败

在Duilib的项目中，有以下的代码：

int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow){    atexit(CheckOnExit);    ::CoInitialize(NULL);    CPaintManagerUI::SetInstance(hInstance);CDuiString str = CPaintManagerUI::GetInstancePath();    CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("skin"));    CDuiFrameWnd *pFrame = new CDuiFrameWnd(_T("XMP.xml"));    pFrame->Create(NULL, _T("迅雷看看播放器"), UI_WNDSTYLE_FRAME, WS_EX_WINDOWEDGE | WS_EX_ACCEPTFILES);    pFrame->ShowModal();    delete pFrame;    ::CoUninitialize();    return 0;}

出现了以下错误：

可以调试代码发现是因为xml文件没有加载成功,可以打断点发现str的值加上"skin"所在的目录没有xml文件，

xml文件具体在哪个文件夹可以根据具体情况进行调整，当把代码调整为如下代码是，可以正常运行：

int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow){    atexit(CheckOnExit);    ::CoInitialize(NULL);    CPaintManagerUI::SetInstance(hInstance);CDuiString str = CPaintManagerUI::GetInstancePath();    CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("..\\..\\_bin\\skin"));    CDuiFrameWnd *pFrame = new CDuiFrameWnd(_T("XMP.xml"));    pFrame->Create(NULL, _T("迅雷看看播放器"), UI_WNDSTYLE_FRAME, WS_EX_WINDOWEDGE | WS_EX_ACCEPTFILES);    pFrame->ShowModal();    delete pFrame;    ::CoUninitialize();    return 0;}
