参考组态手册在wincc5.1中导出短期归档的例子
我写了如下脚本作为导出短期归档的动作，但是系统运行中执行到TLGBackup这个函数时就会报错，希望各位大侠能帮我看看是什么原因。

void ActionForExportingArchive (LPTSTR lpszArchivNameReturn, LPTSTR lpszVariablenName , DWORD dwNumberOfRecords)

{



BOOL fRet;

int iTlgCon = 0;

CMN_ERROR Error;

char szProj[MAX_PATH];

char szFile[MAX_PATH];

LPTSTR lpszArchivName = "PDE#HD#ProcessValueArchive#test1";

char szFileName[MAX_PATH] = "";

LPTSTR lpszFileName;

TLG_IO_BACKUP_SELECT ibs;

DWORD dwSize;

time_t Time;

struct tm* TimeStruct;

int nPathLen,nFileLen;



time(&Time);

TimeStruct = localtime(&Time);



DMGetRuntimeProject( szProj, MAX_PATH, &Error);



nPathLen=strlen(szProj);

nFileLen=strlen((strrchr(szProj,'\\')+1));



strncat(szFile,szProj,nPathLen-nFileLen);

sprintf(szFileName,"%s%s",szFile,"ArchiveBackUp.CSV");

lpszFileName=&szFileName[0];



ibs.sysFrom.wYear = 2009;

ibs.sysFrom.wMonth = 1;

ibs.sysFrom.wDay = 1;

ibs.sysFrom.wHour = 0;

ibs.sysFrom.wMinute = 0;

ibs.sysFrom.wSecond = 0;



ibs.sysTo.wYear = (WORD)(TimeStruct->tm_year+2000);

ibs.sysTo.wMonth = (WORD)(TimeStruct->tm_mon+1);

ibs.sysTo.wDay = (WORD)(TimeStruct->tm_mday);

ibs.sysTo.wHour = (WORD)(TimeStruct->tm_hour);

ibs.sysTo.wMinute = (WORD)(TimeStruct->tm_min);

ibs.sysTo.wSecond = (WORD)(TimeStruct->tm_sec);



fRet = TLGConnect( NULL, &Error );

if (fRet==FALSE) printf("Error in TLGConect(...)\r\n");



fRet=TLGGetBackupSize (lpszArchivName,&dwSize,&ibs,TLG_BACKUP_EVACUATE,TLG_BAKFMT_CSV,&Error);

if (fRet==FALSE) printf("Error in TLGGetBackupSize(...) [%s]\r\n",Error.szErrorText);




fRet=TLGBackup (lpszArchivName,lpszFileName,&ibs,TLG_BACKUP_EXPORT,TLG_BAKFMT_CSV,&Error);

if (fRet==FALSE) printf("Error in TLGBackup(...) [%s]\r\n",Error.szErrorText);





TLGDisconnect( NULL );
