Hello

I assumes that you are trying to read an excel file. Can you send me that file?

any files, and from your samples also:
"C:\Program Files\XLSReadWriteII30\Samples\Delphi\ReadPictures\PictureSample.xls"
or
"C:\Program Files\XLSReadWriteII30\Samples\Delphi\CGI\Format.xls"

On exception Delphi try to open CellStorage2.pas to debug, but file is naturally does not exists in demo package.

I download demo version 3.00.02a - everythings is OK!!!!

Last demo version 3.00.05a has same exception on read file.
Debugging shows, that line 97 in FormulaHandler2.pas (TFormulaHandler.Clear) there is call TList.Clear() which spoils memory used by function TCellStorage.Clear(), that leads to exception. In the version 3.00.02a and before this call wasn't exists. If execution of specified line is skipped then memory overwrite don't occured and file is loaded without any problems.
Debug screens before and after execution of line 97
before:

after
