duilib库可以用于商业项目吗？_course

想将duilib库用于商业项目，不知道行不行?是完全免费的吗？

VC++与duilib相关的问题，程序一直报错，我不知道是哪里有问题_course

上代码，调试到duiFrame.Create(NULL, _T("DUIWnd"), WS_VISIBLE | WS_POPUP, WS_EX_WINDOWEDGE);这一行还没有报错，然后再下一行就显示错误了。 报错显示Debug Assertion Failed #pragma once #include <UIlib.h> #include <string.h> using namespace DuiLib; #ifdef _DEBUG # ifdef _UNICODE # pragma comment(lib, "DuiLib_ud.lib") # else # pragma comment(lib, "DuiLib_d.lib") # endif #else # ifdef _UNICODE # pragma comment(lib, "DuiLib_u.lib") # else # pragma comment(lib, "DuiLib.lib") # endif #endif struct station{ char StationName[13]; char* pOption; char* pLabel; }; enum StopStationState { NotArrive,// 未到站 STOPED,// 已到站 WillArrive,// 将到站 }; class CDuiFrameWnd : public WindowImplBase { public: virtual LPCTSTR GetWindowClassName() const { return _T("DUIMainFrame"); } virtual CDuiString GetSkinFile() { return _T("Qtitle.xml"); } virtual CDuiString GetSkinFolder() { return _T(""); } //duilib窗口的初始化函数 void InitWindow() { // SendMessage(WM_SYSCOMMAND, SC_MAXIMIZE, 0); //窗口的最大化 //struct station cStation = {"佛主岭","Fontc1","surebtn"} ,cStation1,cStation2,cStation3,cStation4,cStation5,cStation6; struct station cStation[13] = {{"佛主岭","Fontc1","surebtn"},{"高新五路","Fontc2","surebtn"},{"高新四路","Fontc3","surebtn"},{"流芳园大街","Fontc4","surebtn"}, {"工程大学","Fontc5","surebtn"},{"光谷大道","Fontc6","surebtn"}}; //strcpy(cStation.StationName,"佛主岭"); CButtonUI* p_surebtn = static_cast<CButtonUI*>(m_pm.FindControl(_T("surebtn"))); //这里获取到的指针可能是空的，可以断点看看 CComboUI* pAccountCombo = static_cast<CComboUI*>(m_pm.FindControl(_T("StationMess"))); CEditUI* pAccountEdit = static_cast<CEditUI*>(m_pm.FindControl(_T("accountedit"))); //指针判断，如果指针为空，直接操作会崩溃?所以都需要判断下，程序健壮性 if(pAccountCombo && pAccountEdit)pAccountEdit->SetText(pAccountCombo->GetText()); pAccountEdit->SetFocus(); } void SetStation(char* station, bool bOpenDoor, StopStationState StationState, bool bShowStopStationPage) { //btnopenDoor.Selected(); //COptionUI* m_Opendoor = static_cast<COptionUI*>(m_pm.FindControl(_T("OpenDoor"))); //COptionUI* m_ShowPage = static_cast<COptionUI*>(m_pm.FindControl(_T("Gloa2"))); //m_Opendoor->Selected(bOpenDoor); //m_ShowPage->Selected(bShowStopStationPage); } void OnPrepare(){ CComboUI* pStationCombo = static_cast<CComboUI*>(m_pm.FindControl(_T("StationMess"))); } virtual void Notify(TNotifyUI& msg) { if(msg.sType == _T("click")) { if(msg.pSender->GetName() == _T("p_surebtn")) { COptionUI* pControl = static_cast<COptionUI*>(m_pm.FindControl(_T("StationChoice"))); } } else if(msg.sType == _T("itemselect")) { if(msg.pSender->GetName() == _T("StationMess")) { //代码有问题,m_pm未初始化？？？ CComboUI* pAccountCombo = static_cast<CComboUI*>(m_pm.FindControl(_T("StationMess"))); pAccountCombo->GetText(); } } } public: CPaintManagerUI m_pm; private: CButtonUI* p_surebtn; }; int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { CPaintManagerUI::SetInstance(hInstance); CDuiFrameWnd duiFrame; duiFrame.Create(NULL, _T("DUIWnd"), WS_VISIBLE | WS_POPUP, WS_EX_WINDOWEDGE); duiFrame.CenterWindow(); duiFrame.ShowModal(); return 0; }
