You can try to compile your python app using IronPython (http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython) to .NET, this should be possible without or just minor changes. This way you can make use of all the .NET features from python.

Then you can decompile your IronPython assembly with an .NET decompiler like Lutz Roeders Reflector (http://www.red-gate.com/products/reflector) which can decompile whole Assemblies into Visual Studio projects. This way you can convert from ANY .NET Langauge into one of the supported languages of this program.

    }

Open in new window


to use it:
static void Main(string[] args)
        {
            STLUtils sTLUtils = new STLUtils();
            if (sTLUtils.IsValidated(args))
            {
                sTLUtils.CalculateVolume();
            }
        }

Hi sedgwick,

there is compilation error at

 return File.Exists(_filename);      <----- error at File


  public double CalculateVolume()
    {
        //read binary file
        _fileBytes = File.ReadAllBytes(_filename);     <----- error at File

How can I run the code in page_load or form load event by providing the STL file to calculate the volume?

I can't upload the sample file, here is the link.
