Example

The following example shows how to return a pointer to the field data indicated by the Plane parameter.

/-------------------------------------------------------------------
// ECLField::GetScreen
//
// Iterate over list of fields and print each fields text contents.
//-------------------------------------------------------------------
void Sample35() {
 
ECLPS        *PS;           // Pointer to PS object
ECLFieldList *FieldList;    // Pointer to field list object
ECLField     *Field;        // Pointer to field object
char         *Buff;         // Screen data buffer
ULONG        BuffLen;
 
try {
  PS = new ECLPS('A');                // Create PS object for 'A'
 
  BuffLen = PS->GetSize() + 1;        // Make big enough for entire screen
  Buff = new char[BuffLen];           // Allocate screen buffer
 
  FieldList = PS->GetFieldList();     // Get pointer to field list
  FieldList->Refresh();               // Build the field list
 
  for (Field = FieldList->GetFirstField();     // First field
    Field != NULL;                             // While more
    Field = FieldList->GetNextField(Field)) {  // Next field
 
      Field->GetScreen(Buff, BuffLen); // Get this fields text
      printf("%02lu,%02lu: %s\n",      // Print "row,col: text"
             Field->GetStartRow(),
             Field->GetStartCol(),
             Buff);
  }
  delete []Buff;
  delete PS;
}
catch (ECLErr Err) {
  printf("ECL Error: %s\n", Err.GetMsgText());
}
 
} // end sample
