Question: When rendering a form field It adds a class that messes up my styling.. All I want to do is remove the class when rendereing the field, but how can I do that? I know that you can set up classes for fields, but I need to remove a default class.

I render like this:

```
{{ form_widget(form.plainPassword }}

```

The only way I can do this now, is go to the vendor `bootstrap_3_horizontal_layout` file and remove the line:

```
{% block form_group_class -%}
    col-sm-10 ///remove this
{%- endblock form_group_class %}

```

However that is not the solution, because you cant manually edit vendor files.. What are my options? How to achieve what I need?

Answer: 
If you want to load an arbitrary code (rather vague expression but let's use it) then you can make a DLL. Then, at run time you can get LoadLibary to load it and GetProcAddress to get a function pointer to the functions exported by the DLL.

I think this is the closest thing you can do in C/C++ to what you describe.
I once did something similar. At first, you should write very simple function in C(++). For example:

```
int add(a, b) {
     return a + b;
}

```

Then compile it as object file (do not link). Then copy the executable code from object file and try to load that into memory.

If you are using executable, you have to parse information in it. Also, you will have to do linking.
