            //here is the problem
            double variabila = 0.00;
            variabila = StrToFloat(txtValue.Text);
            
            
            
       
        }
    }

This is a C++ forum, btw, not C#

bool didConvert = double.TryParse(txtValue.Text, NumberStyles.Any, CultureInfo.InvariantCulture, variabila);

but is at section Windows programming not at general c++!

Yep, but have you read the title of this website?

But anyway, use TryParse

    string text = "3.3";
    float number = 0;
    bool result = true;
    result = float.TryParse(text, out number);
    if(result....

What is not working is the implicitly convert type 'float' to 'string' i.e. txtValue.Text = variabila_doi;. You could use the ToString() method on the float. i.e. txtValue.Text = variabila_doi.ToString();

Thanks is working!
