Excel Range.Find(XlSearchDirection.xlPrevious) bug

[David Thielen]

Hi;

If you use the excel file in http://www.windwardreports.com/temp/PrevBug.zip
and then run the following code - it will not find the previous tag but
instead jumps to the first tag in the spread sheet.

This only happens if starting on a cell that has "</wr:" in it. If starting
anywhere else, it works fine.

Any idea why?
Worksheet xxWs = (Worksheet)app.NativeWorkbook.ActiveSheet;
Range xxSelOn = (Range)xxWs.UsedRange.Cells[11, 1];
// get the row on A:N -> selOn:N
Range xxxSearchRange = xxWs.get_Range(xxWs.UsedRange.Cells[xxSelOn.Row,
1], xxSelOn);
// now get the block from A:1 -> "UsedColumns.Count:row-1"
Range xxxFullRows = xxWs.get_Range(xxWs.UsedRange.Cells[1, 1],
xxWs.UsedRange.Cells[xxSelOn.Row - 1, xxWs.UsedRange.Columns.Count]);
xxxSearchRange = app.NativeApplication.Union(xxxSearchRange,
xxxFullRows, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Range xxxStartAfter = (Range)xxWs.UsedRange.Cells[1, 1];
Range xxxRtn = xxxSearchRange.Find("<wr:", xxxStartAfter,
XlFindLookIn.xlValues, XlLookAt.xlPart, XlSearchOrder.xlByRows,
forward ? XlSearchDirection.xlNext : XlSearchDirection.xlPrevious,
false, false,
Type.Missing);

Hello Dave,

Based on my test, it seems to be an issue of Excel when *Find(xlPrevious)*
or *FindPrevious* is called on a *union* range. When the search reaches the
beginning of the specified range, it does not wrap around to the end of the
range as documented in
http://msdn2.microsoft.com/en-gb/library/microsoft.office.tools.excel.namedr
ange.findprevious(VS.80).aspx.

I am consulting the product team to see if it is an issue of our product. I
will get back to you as soon as possible. Thank you for your reporting.

Happy New Year!

Hello,

I am sorry, Dave. The product team has confirmed that it is an issue of
Excel when calling Find on a union of ranges where the united ranges do not
have the same number of columns / rows so that the union range is not
rectangular. The workaround is to call Find on each range separately.
Please have a try and if you encounter any problem, please do let me know.
I will do my best to help.

Happy New Year!

Does this bug exist for next also, or just previous? And any idea when they
will fix it?

Hello Dave,

According to the response of the product team, the issue may still exist in
the next version due to the backward compatibility. Sorry for the
inconveniences.
