1) Com 如何设置动态字符串？

//char*pTest = "aaaa\0bbbb\0cccc\0dddd\0eeee\0\0";  用0 隔开所有的字符串。

        const int iLength = ;

        char szTemp[iLength] = {};

        //SafeMBSprintf(szTemp,iLength,"%s",pMainUserContainer->GetUser()->GetName().c_str());

        int iIndex = ;

        int iLefeTempBuffSize = iLength;

        char *pTemPointer = szTemp;

        auto iSize = vecOppentName.size();

        for (int i =  ; i < iSize; i++)

        {

            pTemPointer = szTemp + iIndex;

            auto iSize = vecOppentName[i].size();

            SafeMemcpy(pTemPointer,iLefeTempBuffSize,vecOppentName[i].c_str(),iSize);

            iIndex += iSize;

            szTemp[iIndex] = ;

            //This space is set to 0 for spilt

            iIndex ++;

            iLefeTempBuffSize = iLength - iIndex;

        }

        pTemPointer[iIndex++] = ;

        pTemPointer[iIndex] = 

ImGui::Combo(szPosition, &iShowGuardSelectIndex[j], szTemp);

字体

1) 设置默认字体

                ImGui::CreateContext();

                    ImGuiIO& io = ImGui::GetIO();

                    io.Fonts->AddFontDefault();

                    ImFont* font = io.Fonts->AddFontFromFileTTF("font\\FounderCN.ttf", 18.0f, NULL, io.Fonts->GetGlyphRangesChineseFull());

                    IM_ASSERT(font != NULL);

                    ImGui::GetIO().FontDefault = font;

                    ImGui_ImplDX11_Init(device,context);

                    ImGui_ImplWin32_Init(window->WndHandle());

                    ImGui_ImplDX11_CreateDeviceObjects()

2）输入中文必须采用utf8
