Hi,

if you want to use c-script you are able to determine it in runtime through odk functions.

Please note, that in a new version of wincc it could be possible that the tablenames are changed!

Below you will find a c-script that reads out the version number of the wincc project and stores this in a internal tag called "VersionNumber".


[code]// Define our ODK variables
char ProjectName[128];
static char ProjectDSN[128];
CMN_ERRORA Error;
DM_PROJECT_INFO Info;
int i;

// Define our database variables
__object *con=NULL;
__object *rs=NULL;
char connstr[1024];
char VersionNo[1024];

memset(&Error, 0, sizeof(Error));
memset(ProjectName, 0, 128);

// Retrieve CS ProjectName
DMGetRuntimeProjectA(ProjectName, 128, &Error);
DMGetProjectInformationA(ProjectName, &Info, &Error);

// Retrieve CS DSN Name
sprintf(connstr, "DSN=%s", Info.szDSNName);
con = __object_create("ADODB.Connection");
rs = __object_create("ADODB.RecordSet");

// Open Database
con->Open(connstr);

// Check if Connection to DB is successfull.
if (con->State==0)
printf("DB Connection Failed\r\n");
else
{
//printf("Connection Successful\r\n");
rs->Open("SELECT * FROM MCPTPROJECT", con,1);
// Copy value of third column
strcpy(VersionNo, rs->Fields(2));
con->Close();
}

//Free our database objects
__object_delete(rs);
__object_delete(con);

// Set Tag Value from Database.
SetTagChar("VersionNumber",VersionNo);

return 0;
[/code]

Nice code snippet lkkezelf [8)]
