The "List index out of bounds" exception occurs when loading corrupted data using the LoadFromStrings method

created 10 years ago

Hello,
I have a problem with TdxMemData on load CSV file with LoadFromStrings.
If the CSV file is not correctly formed, then I obtain an error “list index out of limit” because the number of values is different to number of fields.
My workaround: I change one line of the code of LoadFromStrings:

Delphi
procedure TdxCustomMemData.LoadFromStrings(AStrings: TStrings);  
...  
          else  
          begin  
            Append;  
            // old line : for J := 0 to AValues.Count - 1 do  
            for J := 0 to Min(AValues.Count, AFields.Count) - 1 do  
              if (AFields[J] <> nil) and (AValues[J] <> '') then  
                TField(AFields[J]).Text := AValues[J];  
            Post;  
          end;  
...

Do you want to apply this patch in the next release?

Thank you.
Best regards.

    Hello Laurent,

    This behavior is by design. As you can see in the "TdxCustomMemData.LoadFromStrings" help topic, "the string list must contain data in the format that is produced by the SaveToStrings method. "
    However, I understand your viewpoint and we will consider your comments. I need to mention though that if we still decide to implement this feature, this will be done in a new major version only.
