HSSF AutoSize Question

 
In the code example below, (b)  my widths ( intWidth ) corresponds with the maximum character width.  But when I open the spread sheet and select a field that was formatted with a style below (a) the field is maxed out to 256.  My numeric fields, are just fine as  I use the
technic below (c).  Isn't there an attribute on the sheet that can be set to enable autosize to work for all columns to accomodate users wishing to manully resize a column without that column expanding to the width of their screen? Do I need to create a data format for all the text fields similar to what I did for the numeric fields?
 
Thanks,
Erick
 
 
(a) styNormal = HSSFWorkbook_createCellStyle(book); HSSFCellStyle_setAlignment(styNormal: ALIGN_LEFT);
 
 
(b)
  IfintRow = 0;
      HSSFSheet_SetColumnWidth( sheet : intCol : intWidth * 256 );
      HSSFSheet_autoSizeColumn(sheet : intWidth );   
 
 
(c)/ styNumeric0 = HSSFWorkbook_createCellStyle(book);/ DataFmt = HSSFWorkbook_createDataFormat(book);/ Str0 = new_String('#,##0');/ NumFmt = HSSFDataFormat_getFormat(DataFmt: Str0);/ HSSFCellStyle_setDataFormat(styNumeric0: NumFmt);/ HSSFCellStyle_setAlignment(styNumeric0: ALIGN_RIGHT);
 EndIf;I am attempting to format my colums so that that they will not only display the cells in a presentable way, but also so that if an attempt is made to manully autosize a column by a user that column will then size to the maxium width of the widest value.
