How can I open an existing Excel file and communicate with it using ActiveX?

I would like an example where ActiveX is used to open an existing spreadsheet to perform read and write operations. I would like to manipulate the data in Excel and then retrieve such changes in MATLAB without having to resave the spreadsheet.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:
The following provides an example of opening an existing Excel file named example.xls and proceeding to write and read with it:
% Specify file name
file = 'D:\Applications\MATLAB701\work\example.xls'; % This must be full path name
% Open Excel Automation server
Excel = actxserver('Excel.Application');
Workbooks = Excel.Workbooks;
% Make Excel visible
Excel.Visible=1;
% Open Excel file
Workbook=Workbooks.Open(file);
% Specify sheet number, data, and range to write to
sheetnum=1;
data=rand(4); % use a cell array if you want both numeric and text data
range = 'F10:I13';
% Make the first sheet active
Sheets = Excel.ActiveWorkBook.Sheets;
sheet1 = get(Sheets, 'Item', sheetnum);
invoke(sheet1, 'Activate');
Activesheet = Excel.Activesheet;
% Put MATLAB data into Excel
ActivesheetRange = get(Activesheet,'Range',range);
set(ActivesheetRange, 'Value', data);
% Here you might manipulate the data in Excel
% Now read the data from the sheet; you could specify a new range here
Range = get(Activesheet,'Range',range);
out = Range.value;
% Save file
invoke(Workbook,'Save')
% Close Excel and clean up
invoke(Excel,'Quit');
delete(Excel);
clear Excel;
