Description Robin Galloway-Lunn 2008-09-08 03:14:35 UTC
HSSFWorkbook.isSheetHidden(int sheetNum) incorrectly returns false for "very hidden" worksheets.

Sheets have 3 visibility states: Visible, Hidden and "Very Hidden".  Very hidden sheets will not even show up in the menu item Format/Sheet/Unhide.  To use this setting on a workbook for verify the bug:

1. open any workbook
2. press <Alt-F11> to enter the VBA editor
3. click on the sheet in the upper left hand "Project" pane.
4. click on the "Visible" property in the "Properties" pane.
5. set the property to "2 - xlSheetVeryHidden"
6. save the workbook and close excel.

Any chance you could upload a file with three sheets, one visible, one hidden and one very hidden? That'd make it easy for someone to compare the flags set on the different sheets, and figure out how much work would be needed to correctly flag these very hidden sheets.

svn now has support for checking if sheets are very hidden, and for setting them to be not hidden, hidden or very hidden.
