Cobra and Excel - a code snippet using .NET Excel Wrapper

Postby ObtuseAngle » Mon Jun 06, 2011 10:58 pm

Greetings Cobra community!

Trying to move from Python and COM access to Excel to Cobra and .NET, after much tearing of hair I eventually gave up on trying to use the Primary Interop Assemblies directly and decided to make use of somebody else's hard work.

There are a few wrappers available, but for my needs .NET Excel Wrapper was fine:
http://excelwrapperdotnet.codeplex.com/
C# usage example and API docs given.

Hugely simplified Cobra snippet:
Code: Select all
use ExcelWrapper

class Program

    def main
        xl = ExcelWrapper.Wrapper()
        xl.open("c:\\temp\\somefile.xls", true)
        c = xl.getCellValue('B2')
        print c
        xl.close


The value of true makes Excel and the workbook visible (briefly, in this example).

Posted in the hope it will lighten somebody else's workload.

Regards, Obtuse.

Excellent. Sometime in the near future, one will be able to conveniently inject @help in their source code to get the API info in a Cobra-friendly fashion, as a pop-up HTML document, like so:

xl = @help ExcelWrapper.Wrapper()


Not quite there yet, but I've started the implementation.

Great!
That will be very (ahem) helpful - getting the API stuff correct is one of my biggest stumbling blocks in Cobra.
