//------------------------------------------------------------------- // ECLFieldList::GetFieldCount // // Display number of fields on the screen. //------------------------------------------------------------------- void Sample40() { ECLPS *PS; // Pointer to PS object ECLFieldList *FieldList; // Pointer to field list object try { PS = new ECLPS('A'); // Create PS object for 'A' FieldList = PS->GetFieldList(); // Get pointer to field list FieldList->Refresh(); // Build the field list printf("There are %lu fields on the screen of connection %c.\n", FieldList->GetFieldCount(), PS->GetName()); delete PS; } catch (ECLErr Err) { printf("ECL Error: %s\n", Err.GetMsgText()); } } // end sample
