The "Invalid stream format" exception when the LoadFromStrings method loads data that includes one or more blanks in the last column

created 10 years ago (modified 10 years ago)

Hello,

I can't load data via MemData.LoadFromTextFile - is says "Invalid stream format". There is no problem in 14.1.6 (and older versions).

Since I don't see any info in breaking changes I'd like to know what's wrong.

    Thank you for your report. I have reproduced the described behavior and forwarded this ticket to our developers for research.

      The error occurs if the last column is empty. Then the procedure which is analysing line content does not add the last field data value, because S is already empty and while condition is not satisfied.
         while (S <> '') and (ADelimiterPos > 0) do
      After that the test
       if AFields.Count = AValues.Count then
      fails. As the data is already empty in the last column there is no reason to set it in the field.
      As a temporary solution the test line in procedure ParseString (dxmdaset.pas) can be changed to
       if AFields.Count >= AValues.Count then

          I will test Mediacom's solution. It appears to work.

            Hello,
            I installed 14.2.5 and I still get LoadFromTextFile : "Invalid stream format". (I use SaveToTextFile to save the file).
