Hello Dave,
1) Find out if the caret is in the text of a cell and if so, the
range selected in that text?
Do you mean to detect if the workbook is in "edit mode" by "if the caret is
in the text of a cell"? According to the response of Excel Product team in
the thread
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=158493&SiteID=1,
Excel does not expose a direct method to detect if it is in edit mode. But
here is a trick for your reference:
http://www.codeproject.com/useritems/Excel_Edit_Mode.asp
When it is in "Edit Mode", most functions of Excel are disabled and VBA
macros are not allowed to run. If your add-in tries to get selected text by
caret in edit mode, it will pop out errors. Therefore, it is suggested to
disable your add-in when users start to edit the cell text.
2) Find out if the caret has selected one or more cells and if so, what
cells?
To get the cells being selected, we could use Application.Selection which
will return a Excel.Range object. Because users may choose non-adjacent
cells, there could be several Areas in the range. (Range.Areas
http://msdn2.microsoft.com/en-us/library/aa213698(office.11).aspx). In each
Area, we could iterate its Cells and get their positions with Range.Left
and Range.Top properties.
3) How do I get/set the text/formula, cell formatting, border,
font, comment, etc for a cell?
Each cell is a Range object.
http://msdn2.microsoft.com/en-us/library/aa174290(office.11).aspx
To set/get the text of a Range, we could use Range.Value2
http://msdn2.microsoft.com/en-us/library/aa215938(office.11).aspx or
Range.Value
http://msdn2.microsoft.com/en-us/library/aa215937(office.11).aspx property.
To set/get the formula, we could set the Formula property:
http://msdn2.microsoft.com/en-us/library/aa160254(office.10).aspx
To set/get the cell formatting and border, we could use NumberFormat
(
http://msdn2.microsoft.com/en-us/library/aa224873(office.11).aspx),
ClearFormats method
(
http://msdn2.microsoft.com/en-us/library/aa223829(office.11).aspx),
Range.Borders property.
Please let me know if you have any other concerns, or need anything else.
Sincerely,
