I tested your code but I have an error
row.Cells[0].Value
cell is not included!!!

OK, that's closer, but it's still not clear. What's the exact error message?

Error 1 'object' does not contain a definition for ' Cells ' and no extension method ' Cells ' accepting a first argument of type 'object' was found ( a using directive or is an assembly reference ? missing)

That doesn't sound right - the Rows[i] indexer is supposed to return a DataGridViewRow, not an object.
Try replacing:
var row = dataGridView1.Rows[i];
with:
DataGridViewRow row = dataGridView1.Rows[i];

Not work ! 
Error 1 Can not implicitly convert type 'object ' to ' System.Data.Odbc.OdbcParameter ' . An explicit conversion exists ( cast he is missing ? )

Once again, command.Parameters.Add(...) returns an OdbcParameter, not an object, so var p0 = command.Parameters.Add(...) should work.
If you were using an older version of .NET which didn't support var, you'd be getting a different error message.
Try specifying the types explicitly - for all of the lines:
var pN = command.Parameters.Add(...);
replace var with OdbcParameter:
OdbcParameter pN = command.Parameters.Add(...);

I notice you haven't posted the error message. 
The first and most obvious problem with that code is that you've replaced the parameter placeholders - ? in the query I posted - with what appears to be column names. That won't work.
The query needs to be:
using (var command = new OdbcCommand("insert into thisdet2 values(?,?,?,?,?,?,?,?,?)", connection))
You should preferably specify the column names explicitly. Assuming the names you used are the column names:
using (var command = new OdbcCommand("insert into thisdet2 (cat,geo,etb,nobl,vend,fam,art,des,tare) values(?,?,?,?,?,?,?,?,?)", connection))

And the error message is?

? is the parameter placeholder for the OdbcCommand and OleDbCommand classes.

Based on what I've seen so far, I would suggest "baby steps".
Start with one "row" and one "cell" / column.
Display the contents of that first cell before attempting to insert it into the database to see if you are actually getting what you're expecting.
Then try a database insert.
When that works, retrieve a few more cells; then a few more rows; etc.
I would also check your "for" loop ... it looks like you are retrieving one less row than there are actual rows (the "while" for a "zero-based" index is "index < count"; not "index < count - 1").
And since "cells" are also a collection, it may be possible to iterate over them in at least some of your code instead of referencing each one of them directly.

Hello once again!
I have been trying to get global hotkeys to work in order for my program to write out certain lines of text without having the form in focus, but I cannot figure out how to use the hook properly.
I'm trying to use this
Processing Global Mouse and Keyboard Hooks in C#[^]
For example, I want my program to send the code of a button when pressing Alt+T. How could I use the code for this?

You should post your question in the forum at the end of the article, and explain exactly what problems you are having.

Thanks, did not realize this.
Done and done.

By extracting the hook portion, and adapting it to send some keys to the active window on a predefined combination.

I tried using the example and adding the UserActivityHook to my project, however, I cannot use it in my form for some reason.
I get this typical error:
Error 1 The type or namespace name 'UserActivityHook' could not be found (are you missing a using directive or an assembly reference?)
I've searched for hours and cannot find what I forgot to do.
