Hi
I need some hints for the following problem.
We have some customer that has one Excel file composed of about 20
sheets and he wants to convert this file to a small C# application.
It's not that he does not want to use Excel at all, but there is data
that has to be entered inside the first sheet and from this data all
other sheets are calulated.
Now he wants us to write some app, where his customers are able to
enter the required data into text-fields and this data should be
passed to an excel file. Doing this excel would calculate all other
sheet-fields.
Now those calculated values must be grabed and passed to an other
excel file, which does NOT hold the formulas for the calculation but
also has some additional charts and graphics which relay on the
calculated values.
This new excel file should then be shown to the user.
I thought of holding the "master" file inside a database and just
opening the excel sheet via automation in memory (just don t call
Show) and pass the entered values to this file and then opening a new
file (from a template) passing the calculated values, deleting the
temporary "master" file and then showing the final one.
The sheets of the "master" file will be password protected (to have at
least a litte security).
What do you think of this approach? Would you recomend to do the
complete proceses different?
_thanks in advance
