判断文件夹名是否是合法YYYYMM格式
1、使用VS2008创建一个带预编译头的控制台项目。
2、源文件内容：
#include "stdafx.h" #define LWW_CONSOLE #ifdef LWW_CONSOLE #define CosPrintf printf #else #define CosPrintf // #endif #include#include #include using namespace std;bool isValidYYYYMM(TCHAR * tcs,int nBeginYYYYMM,int nNowYYYYMM){ int nSize = _tcsclen(tcs); if(nSize != 6) return false; int nYYYYMM = _tstoi(tcs); if((nYYYYMM>=nBeginYYYYMM)&&(nYYYYMM<=nNowYYYYMM)) { return true; } else { return false; }}void getYYYYMM_months(tm * pNowTm,int nSaveMonth,int * pBeginYYYYMM,int *pNowYYYYMM){ int nSaveYear = nSaveMonth/12; int nBeginYear = (pNowTm->tm_year+1900) - nSaveYear; int nSaveMonth12 = nSaveMonth%12; int nBeginMonth = 0; int nNowMonth = pNowTm->tm_mon+1; if(nSaveMonth12 <= nNowMonth) { nBeginMonth = nNowMonth - nSaveMonth12 + 1; } else { nBeginYear--; nSaveMonth12 -= nNowMonth; nBeginMonth = 12 - nSaveMonth12 + 1; } *pBeginYYYYMM = nBeginYear * 100 + nBeginMonth; *pNowYYYYMM = (pNowTm->tm_year+1900) * 100 + nNowMonth; return;}bool getLocalTime(tm * pNowTm) { tm * pTm; time_t nowTime; nowTime = time(NULL); pTm = localtime(&nowTime); memcpy(pNowTm,pTm,sizeof(tm)); return true; } int main( void ) { char ch; int nSaveDay = 60; int nSaveMonth = nSaveDay/30; if(nSaveMonth<=0) nSaveMonth = 1; tm aNowTm; getLocalTime(&aNowTm); int nBeginYYYYMM = 0; int nNowYYYYMM = 0; getYYYYMM_months(&aNowTm,nSaveMonth,&nBeginYYYYMM,&nNowYYYYMM); TCHAR tcsFileName[MAX_PATH] = {0}; _tcscpy(tcsFileName,TEXT("201403")); if(isValidYYYYMM(tcsFileName,nBeginYYYYMM,nNowYYYYMM)) { CosPrintf("isValidYYYYMM\n"); } printf("程序结束\n"); cin>>ch; return 0; }
