I am trying to write a Python script file which analyses data in an
iterative manner. During each iteration, I wish to utilise the Solver
function in Excel to perform some constrained, non-linear fitting to
the data. I have a VBA macro which runs the Solver, and am using
self.xlapp = win32com.client.dynamic.Dispatch("Excel.Application")
..

self.xlapp.run(macro)

I've hit a bit of a brick wall here, and could use some advice. I have
an Access application whose output is a four-tab Excel spreadsheet
where three of the four tabs are the result of database queries.
A number of fields in the queries are designed to become formulae in
Excel after the export has taken place (and they need to be in Excel
rather than Access). I need to use the TransferSpreadsheet Method
rather than the OutputTo to enable...

Can I make an Excel file without having Excel in my PC ?

has anyone every used the solver add-in for Excel? it allows you to solve
linear and non-linear problems given certain conditions. I was wondering if
something like this exists already in .NET? In an application I would like
to solve a model with 500 variables. Excel-Solver can do this but I want to
do it all in code.
any thoughts are appreciated!

The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
