分割字符串

从strFont= L"星期日,星期一,星期二,星期三,星期四,星期五,星期六"中分割出"星期日"至"星期六".

tstring CWidget::SplitFont(tstring strFont, int iFontIndex)
{

     if (tstring::npos != strFont.find(L","))

    {

          for (int i = 0;i < iFontIndex;i++)

         { 

                 int iBeginPos = strFont.find(L",");

                if (iBeginPos != tstring::npos )

                {

                      strFont = strFont.substr(iBeginPos+1);

                }

         }

         if (tstring::npos != strFont.find(L","))

         {

                int iEndPos = strFont.find(L",");

                strFont = strFont.substr(0,iEndPos);

         }

     }

     return strFont;
