ODK with WinCC 7.0

LPTSTRlpszFileName,

PTLG_IO_BACKUP_SELECTlpibs,

DWORDdwJobFlags,

DWORDdwFormatFlags,

PCMN_ERRORlpError );

i create a booton when it is pressed the follow script will be executed:

#include "apdefap.h"
void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
{
SYSTEMTIME sysFrom, sysTo;

sysFrom.wYear=2009;
sysFrom.wMonth=4;
sysFrom.wDay=10;
sysFrom.wHour=0;
sysFrom.wMinute=0;
sysFrom.wSecond=0;
sysFrom.wMilliseconds=0;

sysTo.wYear=2009;
sysTo.wMonth=4;
sysTo.wDay=11;
sysTo.wHour=0;
sysTo.wMinute=0;
sysTo.wSecond=0;
sysTo.wMilliseconds=0;

testexport(sysFrom,sysTo);//Return-Type: long int

}

the function testexport is this global function:

#include "apdefap.h"

int testexport(SYSTEMTIME sysFrom, SYSTEMTIME sysTo)
{

#include"pdertcli.h"
#include"pde_glob.h"
#include"pdertdef.h"
#pragma code("pdertcli.lib")
#pragma code("pdertcli.dll")
#pragma code()

BOOL ret = FALSE;
CMN_ERROR error;
TCHAR szText[255];
HWND hwndParent = NULL;
TLG_IO_BACKUP_SELECT tlg_ibs;
DWORD flag = TLG_BAKFMT_CSV, flag_not_used = 0;
char * FileName = "C:\\test2archive.CSV";
FILE * LogFile;

memset(&error,0,sizeof(CMN_ERROR));
ret = TLGConnect(hwndParent, &error);

if(FALSE == ret)
{
sprintf(szText, "Error in TLGConnect: E1= 0x%08lx ; E2= 0x%08lx ; %s", error.dwError1, error.dwError2, error.szErrorText);
printf("%s\r\n",szText);
}
else
{
sprintf(szText, "TLGConnect");
printf("%s\r\n",szText);
}

printf("file name: %s\r\n",FileName);printf("adress of struct: %d\r\n",tlg_ibs);printf("flag not used: %d\r\n",flag_not_used);printf("flag: %d\r\n",flag);printf("error: %ld\r\n\r\n",error.dwError1);

printf("%04d.%02d.%02d %02d.%02d.%02d\r\n", sysFrom.wYear, sysFrom.wMonth,
sysFrom.wDay, sysFrom.wHour, sysFrom.wMinute,
sysFrom.wSecond);

tlg_ibs.sysFrom = sysFrom;
tlg_ibs.sysTo = sysTo;
tlg_ibs.lpszSqlString = NULL;

TLGExport("ENGPRG02\\ProcessValueArchive", FileName, &tlg_ibs ,flag_not_used, flag, &error);

printf("file name: %s\r\n",FileName);printf("adress of struct: %d\r\n",tlg_ibs);printf("flag not used: %d\r\n",flag_not_used);printf("flag: %d\r\n",flag);printf("error: %ld",error.dwError1);

//error handling
if(error.dwError1 == TLG_API_NO_CONNECTION )
{
printf(": A connection to an activated project has not been established\r\n\r\n");
}
if(error.dwError1 == TLG_API_NO_INTERFACE )
{
printf(": Access to subordinate COM interfaces failed\r\n\r\n");
}
if(error.dwError1 == TLG_API_INVALID_PARAM )
{
printf(": Invalid/incorrect parameter assignment\r\n\r\n");
}
if(error.dwError1 == TLG_API_ERR_SUPPLY )
{
printf(": An error has occurred\r\n\r\n");
}

return 0;
}


When the script is executed i get the next error:

error: 268435504

Dos anyone know Why it didn't work?
Dos anyone know what the error "268435504" means?

Thank for thinking
